The objectives are for the natural resources that form the basis of our existence on this planet to be used sparingly and in a manner that takes the requirements of both nature and humanity into account. You too can help to protect the environment by operating your vehicle in an environmentally responsible manner. Fuel consumption and the rate of engine, transmission, brake and tire wear are affected by these factors: Roperating conditions of your vehicle Ryour personal driving style You can influence both factors. You should bear the following in mind: Operating conditions: Ravoid short trips as these increase fuel con- sumption. make sure that the tire pressures are correct. Rdo not carry any unnecessary weight. Rremove roof racks once you no longer need them. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Ralways have service work carried out at a qualified specialist workshop. Personal driving style: Ralways Rdo not depress the accelerator pedal when starting the engine. Rdo not warm up the engine when the vehicle is stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. frequent, sudden acceleration and braking. Ravoid Rchange gear in good time and use each gear only up to Ô of its maximum engine speed. off the engine in stationary traffic. Rkeep an eye on the vehicle's fuel consumption. Rswitch Environmental concerns and recommendations Wherever the operating instructions require you to dispose of materials, first try to regenerate or re-use them. Observe the relevant environmental rules and regulations when disposing of materials. In this way you will help to protect the environment.

Z 27 28 Introduction Data stored in the vehicle Data recording This vehicle is capable of recording diagnostic information relating to vehicle operation, malfunctions, and user settings. This may include information about the performance or status of various systems, including but not limited to, engine, throttle, steering or brake systems, that is stored and can be read out with suitable devices, particularly when the vehicle is serviced. The data obtained is used to properly diagnose and service your vehicle or to further optimize and develop vehicle functions. COMAND/mbrace If the vehicle is equipped with COMAND or mbrace, additional data about the vehicle’s operation, the use of the vehicle in certain situations, and the location of the vehicle may be compiled through COMAND or the mbrace system. For additional information please refer to the COMAND User Manual and/or the mbrace Terms and Conditions. Event data recorders This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record data that will assist in understanding how a vehicle’s systems performed in certain crash or near crash-like situations, such as during air bag deployment or when hitting a road obstacle. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: Rhow various systems in your vehicle are operating Rwhether or not the driver and passenger seat belts are fastened Rhow far (if at all) the driver is depressing the accelerator and/or brake pedal and fast the vehicle is traveling This data can help provide a better understanding of the circumstances in which crashes and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, can combine the EDR data with the type of personal identification data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehicle or the EDR is needed. In addition to the vehicle manufacturer, other parties that have the special equipment, such as law enforcement, can read the information by accessing the vehicle or the EDR. EDR data may be used in civil and criminal matters as a tool in accident reconstruction, accident claims, and vehicle safety. Since the Crash Data Retrieval CDR tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC ("MBUSA") expressly disclaims any and all liability arising from the extraction of this information by unauthorized Mercedes-Benz personnel. MBUSA will not share EDR data with others without the consent of the vehicle owners or, if the vehicle is leased, without the consent of the lessee. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local government; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law. Warning: The EDR is a component of the Restraint System Module. Tampering with, altering, modifying or removing the EDR component may result in a malfunction of the Restraint System Module and other systems. Rhow Introduction State laws or regulations regarding EDRs that conflict with federal regulation are pre-empted. This means that in the event of such conflict, the federal regulation governs. As of February 2013, 13 states have enacted laws relating to EDRs.

This also applies to safety-related systems and functions. i Read the information on qualified specialist workshops (Y page 26). Panic alarm Occupant safety Restraint system: introduction The restraint system reduces the risk of vehicle occupants coming into contact with parts of the vehicle's interior in the event of an accident. The restraint system can also reduce the forces to which vehicle occupants are subjected during an accident. The restraint system comprises: RSeat belt system bags RChild restraint system RChild seat securing systems The components of the restraint system work in conjunction with each other. They can only deploy their protective function if, at all times, all vehicle occupants: RAir Rhave To activate: press ! button : for at least one second. An alarm sounds and the exterior lighting flashes. X To deactivate: press ! button : again. or X Insert the SmartKey into the ignition lock. or, in vehicles with KEYLESS-GO start-function or KEYLESS‑GO X Press the Start/Stop button. The SmartKey must be in the vehicle. X fastened their seat belts correctly (Y page 45) Rhave adjusted their seat and head restraint properly (Y page 109). As the driver, you also have to make sure that the steering wheel is adjusted correctly. Observe the information relating to the correct driver's seat position (Y page 108). You also have to make sure that an air bag can inflate properly if deployed (Y page 48). An air bag supplements a correctly fastened seat belt and is an additional safety device providing increased protection for vehicle occupants in appropriate accident situations. For example, if, in the event of an accident, the protection offered by the seat belt is sufficient, the air bags are not deployed. When an accident occurs, only the air bags that increase protection in that particular accident situation are deployed. However, seat belts and air bags generally do not protect against objects penetrating the vehicle from the outside. Information on restraint system operation can be found under "Triggering of the Emergency Tensioning Device and air bags" (Y page 56). For more information about children traveling with you in the vehicle and on child restraint systems, see "Children in the vehicle" (Y page 59). Important safety notes G WARNING Modifications to the restraint system may cause it to no longer work as intended. The restraint system may then not perform its intended protective function and may fail in an accident or trigger unexpectedly, for example. This poses an increased risk of injury or even fatal injury. Never modify parts of the restraint system. Never tamper with the wiring, the electronic components or their software. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for further information contact our Customer Assistance Center at 1-800-FOR-MERCedes (1‑800‑367‑6372). Restraint system warning lamp The functions of the restraint system are checked after the ignition is switched on and at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time. The 6 restraint system warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started. The components of the restraint system are in operational readiness. A malfunction has occurred if the 6 restraint system warning lamp: Rdoes not light up after the ignition is switched on Rdoes not go out after a few seconds with the engine running Rlights up again while the engine is running G WARNING If restraint system is malfunctioning, restraint system components may be triggered unintentionally or might not be triggered at all in the event of an accident with a high rate of vehicle deceleration. This can affect the Emergency Tensioning Device or air bag, for example. This poses an increased risk of injury or even fatal injury. Have the restraint system checked and repaired in a qualified specialist workshop as soon as possible. PASSENGER AIR BAG indicator lamp PASSENGER AIR BAG ON indicator lamp : and PASSENGER AIR BAG OFF indicator lamp ; are part of the Occupant Classification System (OCS). The indicator lamps display the status of the front-passenger front air bag. RPASSENGER AIR BAG ON : lights up: the front-passenger front air bag is enabled. If, in the event of an accident, all deployment criteria are met, the front-passenger front air bag is deployed. RPASSENGER AIR BAG OFF ; lights up: the front-passenger front air bag is deactivated. They will then not be deployed in the event of an accident. Z 43 Safety Occupant safety 44 Occupant safety Safety Depending on the person in the frontpassenger seat, the front-passenger front air bag must either be disabled or enabled; see the following points. You must make sure of this both before and during a journey. RChildren in a child restraint system: whether the front-passenger front air bag is enabled or deactivated depends on the installed child restraint system, and the age and size of the child. Therefore, be sure to observe the notes on the "Occupant classification system (OCS)" (Y page 51) and on "Children in the vehicle" (Y page 59). There you will also find instructions on backwards- and forwards-facing child restraint systems on the front-passenger seat. RAll other persons: depending on the classification of the person in the frontpassenger seat, the front-passenger front air bag is enabled or deactivated (Y page 51). Be sure to observe the notes on "Seat belts“ (Y page 44) and "Air bags" (Y page 48). There you can also find information on the correct seat position. Seat belts Introduction A correctly fastened seat belt is the most effective means of restraining the movement of vehicle occupants in the event of an accident or overturn. This reduces the risk of vehicle occupants coming into contact with parts of the vehicle interior or being thrown from the vehicle. Furthermore, the seat belt helps to keep the vehicle occupants in the best position in relation to the air bag. The seat belt system consists of: RSeat belts REmergency Tensioning Devices for the front seat belts and the outer seat belts in the rear compartment RBelt force limiters for the front seat belts and the outer seat belts in the rear If the seat belt is pulled quickly or suddenly from the belt sash guide, the inertia reel locks. The belt strap cannot be pulled out further. Emergency Tensioning Devices tighten the seat belts in an accident, pulling them close against the occupant's body. They do not, however, pull vehicle occupants back towards the backrest. Emergency Tensioning Devices do not correct an incorrect seat position or incorrectly worn seat belts. When activated, the belt force limiters reduce the force exerted by the seat belt on the vehicle occupants. The belt force limiters for the front seats are synchronized with the front air bags, which absorb part of the deceleration force. This makes it possible to reduce the forces to which vehicle occupants are subjected during an accident. ! If the front-passenger seat is unoccupied, do not insert the belt tongue into the buckle of the front-passenger seat. This may otherwise lead to the triggering of the Emergency Tensioning Device in the event of an accident, which will then need to be replaced. Important safety notes The use of seat belts and child restraint systems is required by law in: Rall 50 states Rthe U.S. territories Rthe District of Columbia Rall Canadian provinces Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey. G WARNING If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for example, in an accident, dur- ing braking or when abruptly changing direction. This poses an increased risk of injury or even fatal injury. Make sure that all vehicle occupants are seated properly with a correctly fastened seat belt. G WARNING The seat belt does not offer the intended level of protection if you have not moved the backrest to an almost vertical position. When braking or in the event of an accident, you could slide underneath the seat belt and sustain abdomen or neck injuries, for example. This poses an increased risk of injury or even fatal injury. Adjust the seat properly before beginning your journey. Always ensure that the backrest is in an almost vertical position and that the shoulder section of your seat belt is routed across the center of your shoulder. G WARNING Persons under 5 ft (1.50 m) in height cannot fasten the seat belt correctly without an additional suitable restraint system. If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an incorrectly fastened seat belt can cause additional injury, for example, in an accident, during braking or an abrupt change of direction. This poses an increased risk of injury or even fatal injury. For this reason, always secure persons under 5 ft (1.50 m) in height in suitable restraint systems. If a child younger than 12 years and under 5 ft (1.50 m) in height is traveling in the vehicle: Ralways secure the child in a child restraint system suitable for this Mercedes-Benz vehicle. The child restraint system must be appropriate to the age, weight and size of the child Ralways observe the instructions and safety notes in the "Children in the vehicle" section of this Operator's Manual (Y page 59) in addition to the child restraint system manufacturer's installation instructions Rbe sure to observe the instructions and safety notes on the "Occupant classification system (OCS)" (Y page 51) G WARNING The seat belts may not perform their intended protective function if: Rthey are damaged, modified, extremely dirty, bleach or dyed Rthe seat belt buckle is damaged or extremely dirty Rthe Emergency Tensioning Devices, belt anchorages or inertia reels have been modified Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modified or damaged seat belts may tear or fail, e.g. in an accident. Modified Emergency Tensioning Devices could accidentally trigger or fail to deploy when necessary. This poses an increased risk of injury or even fatal injury. Never modify the seat belts, Emergency Tensioning Devices, belt anchorages or inertia reels. Make sure that the seat belts are undamaged, not worn out and clean. Following an accident, have the seat belts checked immediately at a qualified specialist workshop. Only use seat belts that have been approved for your vehicle by Mercedes-Benz. Any such modifications could invalidate the vehicle's general operating permit. Proper use of the seat belts Observe the safety notes on the seat belt (Y page 44). All vehicle occupants must be wearing the seat belt correctly before beginning the journey. Also make sure that all vehicle occupants are always wearing the seat belt correctly while the vehicle is in motion. Z 45 Safety Occupant safety 46 Occupant safety When fastening the seat belt, always make sure that: Safety Rthe seat belt tongue is only inserted to the belt buckle belonging to that seat. Rthe seat belt is tight across your body. Avoid wearing bulky clothing, e.g. a winter coat. Rthe seat belt is not twisted. Only then can the forces which occur be distributed over the area of the belt. Rthe shoulder section of the belt is always routed across the center of your shoulder. The shoulder section of the belt must not come into contact with your neck or be routed under your arm. Where possible, adjust the seat belt to the appropriate height. Rthe lap belt passes tightly and as low down as possible across your lap. The lap belt must always be routed across your hip joints and not across your abdomen. This applies particularly to pregnant women. If necessary, push the lap belt down to your hip joint and pull it tight using the shoulder section of the belt. Rthe seat belt is not routed across sharp, pointed or fragile objects. If you have such items located on or in your clothing, e.g. pens, keys or eyeglasses, store these in a suitable place. Ronly one person is using a seat belt at a time. Infants and children must never travel sitting on the lap of a vehicle occupant. In the event of an accident, they could be crushed between the vehicle occupant and seat belt. Robjects are never secured with a seat belt if the seat belt is also being used by one of the vehicle's occupants. Seat belts are only intended to secure and restrain vehicle occupants. Always observe the "Loading guidelines" for securing objects, luggage or loads (Y page 298). Fastening and adjusting the seat belts Please take note of the safety notes on seat belts (Y page 44) and the notes on their correct use (Y page 45). If the center rear seat belt is used, observe the information about the seat belt for the center rear seat (Y page 47). Adjust the seat (Y page 108). The seat backrest must be in an almost upright position. X Pull the seat belt smoothly out of belt outlet = and engage belt tongue ; in buckle :. The driver's and front-passenger's seat belts are automatically pulled taut as required, see “Belt adjustment” (Y page 47). X If necessary, pull upwards on the shoulder section of the seat belt to tighten the belt across your body. X Occupant safety 47 The shoulder section of the belt must always run over the center of the shoulder. Adjust the belt outlet if necessary. To raise: slide the belt outlet upwards. The belt outlet engages in various positions. X To lower: slide the belt outlet downward, pressing belt outlet release catch :. X Once the desired position has been reached, release belt outlet release catch : and ensure the belt outlet engages in place. All seat belts in the vehicle, except the driver's seat belt, are equipped with a special seat belt retractor to secure child restraint systems properly. Further information can be found under "Special seat belt retractor" (Y page 60). Safety X X Press release button :, hold belt tongue ; firmly and guide it back towards belt outlet =. Seat belt for the center rear seat Seat belt adjustment If the left-hand rear seat backrest is folded down and back up again, the rear center seat belt may lock. The seat belt can then not be pulled out. X To release the rear center seat belt: pull the seat belt out approximately 1 in (25 mm) at the belt outlet on the backrest and then release it again. The seat belt is retracted and released. The seat-belt adjustment is an integral part of the PRE-SAFE® convenience function. This function adjusts the driver's and frontpassenger seat belt to the upper body of the occupants. The belt strap is tightened slightly when: Releasing seat belts ! Make sure that the seat belt is fully rolled up. Otherwise, the seat belt or belt tongue will be trapped in the door or in the seat mechanism. This could damage the door, the door trim panel and the seat belt. Damaged seat belts can no longer fulfill their protective function and must be replaced. Visit a qualified specialist workshop. Rthe belt tongue is engaged in the buckle and Rthe ignition is switched on The seat-belt adjustment will apply a certain tightening force if any slack is detected between the vehicle occupant and the seat belt. Do not hold on to the seat belt tightly while it is adjusting. You can switch the seat-belt adjustment on and off using COMAND or Audio 20. Information on activating and deactivating the seatbelt adjustment function can be found in the Digital Operator's Manual or in the separate COMAND or Audio 20 operating instructions. Z 48 Occupant safety Safety Belt warning for the driver and front passenger The 7 seat belt warning lamp in the instrument cluster is a reminder that all occupants must fasten their seat belts. It may light up continuously or flash. In addition, there may be a warning tone. Regardless of whether the driver's and frontpassenger seat belts have already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the engine is started. If, after six seconds, the driver or front-passenger seat belt has not been fastened and the doors are closed, the 7 seat belt warning lamp lights up. As soon as the driver's and front-passenger seat belts are fastened or a front door is opened again, the 7 seat belt warning lamp goes out. If the driver's seat belt is not fastened after the engine is started, an additional warning tone will sound. This warning tone stops after six seconds or when the driver's seat belt is fastened. If the vehicle's speed exceeds 15 mph (25 km/h) once and the driver's and frontpassenger seat belts are not fastened, a warning tone sounds. A warning tone also sounds with increasing intensity for 60 seconds or until the driver or front passenger have fastened their seat belts. If the driver or front passenger unfasten their seat belts during the journey, the seat belt warning is activated again. i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belts" (Y page 284). Air bags Introduction The installation point of an air bag can be recognized by the AIR BAG symbol. An air bag complements the correctly fastened seat belt. It is no substitute for the seat belt. The air bag provides additional protection in applicable accident situations. Not all air bags are deployed in an accident. The different air bag systems function independently from one another (Y page 56). However, no system available today can completely eliminate injuries and fatalities. It is also not possible to rule out a risk of injury caused by an air bag due to the high speed at which the air bag must be deployed. Important safety notes G WARNING If you do not sit in the correct seat position, the air bag cannot protect as intended and could even cause additional injury when deployed. This poses an increased risk of injury or even fatal injury. To avoid hazardous situations, always make sure that all of the vehicle's occupants: Rhave fastened their seat belts correctly, including pregnant women Rare sitting correctly and maintain the greatest possible distance to the air bags Rfollow the following instructions Always make sure that there are no objects between the air bag and the vehicle's occupants. RAdjust the seats properly before beginning your journey. Always make sure that the seat is in an almost upright position. The center of the head restraint must support the head at about eye level. RMove the driver's and front-passenger seats as far back as possible. The driver's seat position must allow the vehicle to be driven safely. ROnly hold the steering wheel on the outside. This allows the air bag to be fully deployed. RAlways lean against the backrest while driving. Do not lean forwards or lean against the door or side window. You may other- wise be in the deployment area of the air bags. RAlways keep your feet in the footwell in front of the seat. Do not put your feet on the dashboard, for example. Your feet may otherwise be in the deployment area of the air bag. RFor this reason, always secure persons less than 5 ft (1.50 m) tall in suitable restraint systems. Up to this height, the seat belt cannot be worn correctly. If a child is traveling in your vehicle, also observe the following notes: RAlways secure children under 12 years of age and less than 5 ft (1.50 m) in height in suitable child restraint systems. RChild restraint systems should be installed on the rear seats. ROnly secure a child in a rearward-facing child restraint system to the frontpassenger seat when the front-passenger front air bag is disabled. If the PASSENGER AIR BAG OFF indicator lamp is permanently lit, the front-passenger front air bag is disabled (Y page 43). RAlways observe the instructions and safety notes on the "Occupant Classification System (OCS)" (Y page 51) and on "Children in the vehicle" (Y page 59) in addition to the child restraint system manufacturer's installation instructions. Objects in the vehicle interior may prevent the air bag from functioning correctly. Before starting your journey and to avoid risks resulting from the speed of the air bag as it deploys, make sure that: are no people, animals or objects between the vehicle occupants and an air bag. Rthere are no objects between the seat, door and B-pillar. Rno hard objects, e.g. coat hangers, hang on the grab handles or coat hooks. Rno accessories, such as cup holders, are attached to the vehicle within the deploy- ment area of an air bag, e.g. to doors, side windows, rear side trim or side walls. Rno heavy, sharp-edged or fragile objects are in the pockets of your clothing. Store such objects in a suitable place. G WARNING If you modify the air bag cover or affix objects such as stickers to it, the air bag can no longer function correctly. There is an increased risk of injury. Never modify an air bag cover or affix objects to it. G WARNING Sensors to control the air bags are located in the doors. Modifications or work not performed correctly to the doors or door paneling, as well as damaged doors, can lead to the function of the sensors being impaired. The air bags might therefore not function properly any more. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. There is an increased risk of injury. Never modify the doors or parts of the doors. Always have work on the doors or door paneling carried out at a qualified specialist workshop.

Side impact air bags G WARNING Unsuitable seat covers could restrict or even prevent the deployment of the air bags integrated into the seats. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, the function of the Occupant Classification System In the event of a side impact, the side impact air bag is deployed on the side on which the impact occurs. The side impact air bag on the frontpassenger side (front) deploys in the following situations: Rthe OCS system detects that the frontpassenger seat is occupied or Rthe belt tongue is engaged in the belt buckle of the front-passenger seat If the belt tongue is engaged in the belt buckle, the side impact air bag on the frontpassenger side deploys if an appropriate accident situation occurs. In this case, deployment is independent of whether the frontpassenger seat is occupied or not. Occupant safety Window curtain air bags 51 Prerequisites To be classified correctly, the front passenger must sit: the seat belt fastened correctly an almost upright position with their back against the seat backrest Rwith their feet resting on the floor, if possible If the front passenger does not observe these conditions, OCS may produce a false classification, e.g. because the front passenger: Window curtain air bags : are integrated into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar. When deployed, the window curtain air bag enhances the level of protection for the head. However, it does not protect the chest or arms. In the event of a side impact, the window curtain air bag is deployed on the side on which the impact occurs. If the system determines that they can offer additional protection to that provided by the seat belt, a window curtain air bag may be deployed in other accident situations (Y page 56).

X Press the Start/Stop button once or twice, or turn the SmartKey to position 1 or 2 in the ignition lock. The system carries out a self-diagnosis. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps must light up simultaneously for approximately six seconds. The indicator lamps display the status of the front-passenger front air bag. RPASSENGER AIR BAG ON : lights up: the front-passenger front air bag is enabled. If, in the event of an accident, all deployment criteria are met, the front-passenger front air bag is deployed. RPASSENGER AIR BAG OFF ; lights up: the front-passenger front air bag is deactivated. They will then not be deployed in the event of an accident. If the status of the front-passenger front air bag changes while the vehicle is in motion, an air bag display message appears in the instrument cluster (Y page 263). When the frontpassenger seat is occupied, always pay attention to the PASSENGER AIR BAG ON and PASSENGER AIR BAG OFF indicator lamps. Be aware of the status of the front-passenger If the PASSENGER AIR BAG OFF indicator lamp is lit, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident and cannot perform its intended protective function. A person in the frontpassenger seat could then, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always ensure that: Rthe classification of the person in the front- passenger seat is correct and the frontpassenger front air bag is enabled or disabled in accordance with the person in the front-passenger seat Rthe front-passenger seat has been moved back as far back as possible. Rthe person is seated correctly. Make sure, both before and during the journey, that the status of the front-passenger front air bag is correct. G WARNING If you secure a child in a rearward-facing child restraint system on the front-passenger seat and the PASSENGER AIR BAG ON indicator lamp is lit up, the front-passenger front air bag may deploy in an accident. The child could be struck by the air bag. This poses an increased risk of injury or even fatal injury. Make sure that the front-passenger front air bag has been disabled. The PASSENGER AIR BAG OFF indicator lamp must be lit. If the PASSENGER AIR BAG OFF indicator lamp remains off and/or the PASSENGER AIR BAG ON indicator lamp lights up, do not install a rearward-facing child restraint system on the front-passenger seat. You can find more information on OCS under "Problems with the Occupant Classification System" (Y page 55). G WARNING If you secure a child in a forward-facing child restraint system on the front-passenger seat and you position the front-passenger seat too close to the dashboard, in the event of an accident, the child could: Rcome into contact with the vehicle's interior if the PASSENGER AIR BAG OFF indicator lamp is lit, for example Rbe struck by the air bag if the PASSENGER AIR BAG ON is lit up This poses an increased risk of injury or even fatal injury. Always move the front-passenger seat as far back as possible and fully retract the seat cushion length. Always make sure that the shoulder belt strap is correctly routed from the vehicle belt sash guide to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards and downwards from the vehicle belt sash guide. If necessary, adjust the vehicle belt sash guide and the front-passenger seat accordingly. Always observe the child restraint system manufacturer's installation instructions. If OCS determines that: Rthe front-passenger seat is unoccupied, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the frontpassenger front air bag is deactivated. Rthe front-passenger seat is occupied by a child of up to 12 months old, in a standard child restraint system, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the front-passenger front air bag is deactivated. But in the case of a 12-month-old child, in a standard child restraint system, the PASSENGER AIR BAG ON can light up permanently after the system self-test. This indicates that the front-passenger front air bag is activated. The result of the classification is dependent on, among other factors, the child restraint system and the child's stature. It is recommended that you install the restraint system on a suitable rear seat. Rthe front-passenger seat is occupied by a person of smaller stature (e.g. a teenager or small adult), either the PASSENGER AIR BAG ON or PASSENGER AIR BAG OFF indicator lamp lights up and remains lit after the system self-test depending on the result of the classification. - if the PASSENGER AIR BAG ON indicator lamp lights up, move the front-passenger seat as far back as possible. Alternatively, a person of smaller stature can sit on a rear seat. - if the PASSENGER AIR BAG OFF indicator lamp is lit, a person of smaller stature should not use the front-passenger seat. Rthe front-passenger seat is occupied by an adult or a person of a stature corresponding to that of an adult, the PASSENGER AIR BAG ON indicator lamp lights up after the system self-test and remains lit. This indicates that the front-passenger front air bag is activated. If children are traveling in the vehicle, be sure to observe the notes on "Children in the vehicle" (Y page 59). When OCS is malfunctioning, the red 6 restraint system warning lamp in the instrument cluster and the PASSENGER AIR BAG OFF indicator lamp light up simultaneously. The front-passenger front air bag is deactivated in this case and does not deploy during an accident. Have the system checked by qualified technicians as soon as possible. Consult an authorized Mercedes-Benz Center. The front-passenger seat should only be repaired at an authorized Mercedes-Benz Center. If the front-passenger seat, the seat cover or the seat cushion is damaged, have the nec- Z 53 Safety Occupant safety Safety 54 Occupant safety essary repair work carried out at an authorized Mercedes-Benz Center. For safety reasons, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The Occupant Classification System (OCS) categorizes the occupant in the front-passenger seat. Depending on that result, the front-passenger front air bag is either enabled or deactivated. System self-test G DANGER If both the PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps do not light up during the system self-test, the system is malfunctioning. The frontpassenger front air bag might be triggered unintentionally or might not be triggered at all in the event of an accident with high deceleration. This poses an increased risk of injury or even fatal injury. In this case the front-passenger seat may not be used. Do not install a child restraint system on the front-passenger seat. Have the Occupant Classification System (OCS) checked and repaired immediately at a qualified specialist workshop. G DANGER If the PASSENGER AIR BAG OFF indicator lamp remains lit after the system self-test, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident. In this case, the front-passenger front air bag cannot perform its intended protective function, e.g. when a person is seated in the frontpassenger seat. That person could, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always ensure that: Rthe classification of the person in the front- passenger seat is correct and the frontpassenger front air bag is enabled or disabled in accordance with the person in the front-passenger seat Rthe person is seated properly with a correctly fastened seatbelt Rthe front-passenger seat has been moved back as far back as possible If the PASSENGER AIR BAG OFF indicator lamp remains lit when it should not, the frontpassenger seat may not be used. Do not install a child restraint system on the frontpassenger seat. Have the Occupant Classification System (OCS) checked and repaired immediately at a qualified specialist workshop. G WARNING Objects between the seat surface and the child restraint system could affect OCS operation. This could result in the front-passenger air bag not functioning as intended during an accident. This poses an increased risk of injury or even fatal injury. Do not place any objects between the seat surface and the child restraint system. The entire base of the child restraint system must always rest on the seat cushion of the frontpassenger seat. The backrest of the forwardsfacing child restraint system must, as far as possible, be resting on the backrest of the front-passenger seat.

Z Safety Problem 56 Occupant safety Deployment of Emergency Tensioning Devices and air bags Safety Important safety notes G WARNING The air bag parts are hot after an air bag has been deployed. There is a risk of injury. Do not touch the air bag parts. Have a deployed air bag replaced at a qualified specialist workshop as soon as possible. G WARNING A deployed air bag no longer offers any protection and cannot provide the intended protection in an accident. There is an increased risk of injury. Have the vehicle towed to a qualified specialist workshop in order to have a deployed air bag replaced. It is important for your safety and that of your passenger to have deployed air bags replaced and to have any malfunctioning air bags repaired. This will help to make sure the air bags continue to perform their protective function for the vehicle occupants in the event of a crash. G WARNING Pyrotechnic Emergency Tensioning Devices that have been deployed are no longer operational and are unable to perform their intended protective function. This poses an increased risk of injury or even fatal injury. Therefore, have pyrotechnic Emergency Tensioning Devices which have been triggered immediately replaced at a qualified specialist workshop. An electric motor is used by PRE-SAFE® to trigger the tightening of the seat belt in hazardous situations. This procedure is reversible. If Emergency Tensioning Devices or air bags are deployed, you will hear a bang, and a small amount of powder may also be released. The 6 restraint system warning lamp lights up. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard, but it may cause short-term breathing difficulties in people with asthma or other respiratory problems. To avoid this, you may wish to get out of the vehicle or open the windows as soon as it is safe to do so. Air bags and pyrotechnic Emergency Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and regard for the environment. National guidelines must be observed during disposal. In California, see www.dtsc.ca.gov/ HazardousWaste/Perchlorate/ index.cfm. Method of operation During the first stage of a collision, the restraint system control unit evaluates important physical data relating to vehicle deceleration or acceleration, such as: Rduration Rdirection Rintensity Based on the evaluation of this data, the restraint system control unit deploys the Emergency Tensioning Devices during a frontal or rear collision. An Emergency Tensioning Device can only be deployed, if: Rthe ignition is switched on Rthe components of the restraint system are operational; see "Restraint system warning lamp" (Y page 43) Rthe belt tongue is engaged in the buckle on the respective front-passenger seat The Emergency Tensioning Devices in the rear compartment are deployed independently of the lock status of the seat belts. If the restraint system control unit detects a more severe accident, further components of the restraint system are activated independently of each other in certain frontal collision situations: RFront air bags and driver's knee bag RWindow curtain air bag, if the system deter- mines that deployment can offer additional protection to that provided by the seat belt The front-passenger front air bag is activated or deactivated depending on the person on the front-passenger seat. The frontpassenger front air bag can only deploy in an accident if the PASSENGER AIR BAG ON indicator lamp is lit. Observe the information on the PASSENGER AIR BAG indicator lamps(Y page 43). Your vehicle has two-stage front air bags. During the first deployment stage, the front air bag is filled with propellant gas to reduce the risk of injuries. The front air bag is fully deployed with the maximum amount of propellant gas if a second deployment threshold is reached within a few milliseconds. The deployment threshold of the Emergency Tensioning Devices and the air bag are determined by evaluating the rate of vehicle deceleration or acceleration which occurs at various points in the vehicle. This process is preemptive in nature. Deployment should take place in good time at the start of the collision. The rate of vehicle deceleration or acceleration and the direction of the force are essentially determined by: Rthe distribution of forces during the collision Rthe collision angle Rthe deformation characteristics of the vehicle Rthe characteristics of the object with which the vehicle has collided Factors that can only be seen and measured after a collision has occurred do not play a decisive role in the deployment of an air bag, nor do they provide an indication of air bag deployment. The vehicle can be deformed considerably, without an air bag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of deceleration is not high. Conversely, air bags may be deployed even though the vehicle suffers only minor deformation. This is the case if, for example, very rigid vehicle parts such as longitudinal body members are hit, and sufficient deceleration occurs as a result. If the restraint system control unit detects a side impact or that the vehicle is rolling over, the relevant restraint system components are activated independently of one another depending on the apparent type of accident. If the system determines a need for additional protection for the vehicle occupants, the Emergency Tensioning Devices are deployed. RSide impact air bags on the side of impact, independently of the Emergency Tensioning Device and the use of the seat belt on the driver's seat and outer seats in the second row The side impact air bag on the frontpassenger side (front) deploys in the following situations: - the OCS system detects that the frontpassenger seat is occupied or - the belt tongue is engaged in the belt buckle of the front-passenger seat RWindow curtain air bag on the side of impact, independently of the use of the seat belt and independently of whether the front-passenger is occupied RWindow curtain air bags on the driver's and front-passenger side in certain situations when the vehicle rolls over, if the system determines that deployment can offer additional protection to that provided by the seat belt i Not all air bags are deployed in an accident.

PRE-SAFE® PLUS does not perform braking actions while the vehicle is in motion or when Parking Guidance is active. Function PRE-SAFE® PLUS intervenes in certain situations if the radar sensor system detects an imminent head-on or rear-end collision. PRE-SAFE® PLUS takes the following measures depending on the hazardous situation detected: Rif the radar sensor system detects that a head-on collision is imminent, the seat belts are pre-tensioned. Rif the radar sensor system detects that a rear-end collision is imminent: - the brake pressure is increased if the driver applies the brakes when the vehicle is stationary. - the seat belts are pre-tensioned. The PRE-SAFE® PLUS braking application is canceled: Rif the accelerator pedal is depressed when a gear is engaged Rif the risk of a collision passes or is no longer detected Rif DISTRONIC PLUS indicates an intention to pull away If the hazardous situation passes without resulting in an accident, the original settings are restored. Automatic measures after an accident Immediately after an accident, the following measures are implemented, depending on the type and severity of the impact: Rthe hazard warning lamps are activated emergency lighting is activated Rthe vehicle doors are unlocked Rthe front side windows are lowered Rvehicles with a memory function: the electrically adjustable steering wheel is raised Rthe engine is switched off Rvehicles with mbrace: automatic emergency call Rthe Children in the vehicle Important safety notes Accident statistics show that children secured in the rear seats are safer than children secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat. Children are generally better protected there. If a child younger than 12 years and under 5 ft (1.50 m) in height is traveling in the vehicle: Ralways secure the child in a child restraint system suitable for Mercedes-Benz vehicles.

LATCH-type (ISOFIX) securing rings : for two LATCH-type (ISOFIX) child restraint systems are installed on the left and right rear seats. Non-LATCH-type (ISOFIX) child seats may also be used and can be installed using the vehicle's seat belt system. Install child seats according to the manufacturer's instructions. Top Tether Introduction Top Tether provides an additional connection between the child restraint system secured with a LATCH-type (ISOFIX) child seat mount and the vehicle. This helps reduce the risk of injury even further. If the child restraint system is equipped with a Top Tether belt, this should always be used. Children in the vehicle 63 G WARNING If the rear seat backrests are not locked, they could fold forwards in the event of an accident, heavy braking or sudden changes of direction. As a result, child restraint systems cannot perform their intended protective function. Rear seat backrests that are not locked can also cause additional injuries, e.g. in the event of an accident. This poses an increased risk of injury or even fatal injury. Always lock rear seat backrests after installing a Top Tether belt. Observe the lock verification indicator. Adjust the rear seat backrests so that they are in an upright position. If the rear seat backrest is not engaged and locked, this will be shown in the multifunction display in the instrument cluster.

Driving safety systems Overview of driving safety systems In this section, you will find information about the following driving safety systems: RABS (Anti-lock Braking System) (Y page 66) RBAS (Brake Assist System) (Y page 67) RBAS PLUS with Cross-Traffic Assist (Brake Assist System PLUS with Cross-Traffic Assist) (Y page 67) RCOLLISION PREVENTION ASSIST PLUS (distance warning function and adaptive Brake Assist) (Y page 69) RESP® (Electronic Stability Program) (Y page 71) REBD (Electronic Brake force Distribution) (Y page 73) RADAPTIVE BRAKE (Y page 74) RPRE-SAFE® Brake (Y page 74) RSTEER CONTROL (Y page 76) Important safety notes If you fail to adapt your driving style or become distracted, the driving safety systems can neither reduce the risk of accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road, weather and traffic conditions and maintain a safe distance from the vehicle in front. Drive carefully. The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Please pay special attention to the notes on tires, recommended minimum tire tread depths, etc. (Y page 358). In wintry driving conditions, always use winter tires (M+S tires) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible. ABS (Anti-lock Braking System) General information ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. The ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running. Important safety notes i Observe the "Important safety notes" section (Y page 66). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop. When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 286) and display messages which may be shown in the instrument cluster (Y page 251). Driving safety systems Braking If ABS intervenes: continue to depress the brake pedal vigorously until the braking situation is over. X To make a full brake application: depress the brake pedal with full force. X If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving. BAS (Brake Assist System) General information BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. Important safety notes i Observe the "Important safety notes" section (Y page 66). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking. Braking X Keep the brake pedal firmly depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will function as usual once you release the brake pedal. BAS is deactivated. BAS PLUS (Brake Assist System PLUS) with Cross-Traffic Assist General information i Observe the "Important safety notes" section (Y page 66). BAS PLUS is only available on vehicles with the Driving Assistance package. For BAS PLUS to assist you when driving, the radar sensor system and the camera system must be operational. With the help of a sensor system and a camera system, BAS PLUS can detect obstacles: Rthat are in the path of your vehicle for an extended period of time Rthat cross the path of your vehicle In addition, pedestrians in the path of your vehicle can be detected. BAS PLUS detects pedestrians by using typical characteristics such as the body contours and posture of a person standing upright. If the radar sensor system or the camera system is malfunctioning, BAS PLUS functions are restricted or no longer available. The brake system is still available with complete brake boosting effect and BAS. i Observe the restrictions described in the "Important safety notes" section“ (Y page 67). BAS PLUS can help you to minimize the risk of a collision with a vehicle or a pedestrian and reduce the effects of such a collision. If BAS PLUS detects a danger of collision, you are assisted when braking. Important safety notes G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. Z Safety ABS works from a speed of about 5 mph (8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even when you only brake gently. 67 68 Driving safety systems In such cases, BAS PLUS may: Rintervene unnecessarily intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. Safety Rnot G WARNING BAS PLUS does not react: Rto small people, e.g. children animals Rto oncoming vehicles Rwhen cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto In the event of snowfall or heavy rain, the recognition can be impaired. Recognition by the radar sensor system is also impaired in the event of: Rthere is dirt on the sensors or anything else covering the sensors Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line Rvehicles quickly moving into the radar sensor system detection range Recognition by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is covered Rthere is glare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif: pedestrians move quickly, e.g. into the path of the vehicle - the camera system no longer recognizes a pedestrian as a person due to special clothing or other objects - a pedestrian is concealed by other objects - the typical outline of a person is not distinguishable from the background Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Following damage to the windshield, have the configuration and operation of the camera system checked at a qualified specialist workshop. - Function To avoid a collision, BAS PLUS calculates the brake force necessary if: Ryou approach an obstacle, and PLUS has detected a risk of collision When driving at a speed under 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. The increase in brake pressure will be carried out at the last possible moment. When driving at a speed above 20 mph (30 km/h): if you depress the brake pedal sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the traffic situation. BAS PLUS provides braking assistance in hazardous situations with vehicles in front within a speed range between 4 mph (7 km/h) and 155 mph (250 km/h). RBAS Driving safety systems Rstationary objects in the path of your vehicle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle Robjects crossing your path and that are recognized in the detection range of the sensors i If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. BAS PLUS is deactivated and the brakes function as usual again, if: Ryou release the brake pedal. is no longer a risk of collision. Rno obstacle is detected in front of your vehicle. Ryou depress the accelerator pedal. Ryou activate kickdown. Rthere COLLISION PREVENTION ASSIST PLUS General information COLLISION PREVENTION ASSIST PLUS consists of a distance warning function with an autonomous emergency braking function and adaptive Brake Assist. COLLISION PREVENTION ASSIST PLUS can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If COLLISION PREVENTION ASSIST PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. If you do not react to the visual and audible collision warning, autonomous braking can be initiated in critical situations. If you apply the brake yourself in a critical situation, the COLLISION PREVENTION ASSIST PLUS adaptive Brake Assist assists you. Important safety notes In particular, the detection of obstacles can be impaired if: Rthere is dirt on the sensors or anything else covering the sensors is snow or heavy rain Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line Rnew vehicles or after a service on the COLLISION PREVENTION ASSIST PLUS system Observe the notes in the section on breaking-in (Y page 156). Following damage to the front end of the vehicle, have the configuration and operation of the radar sensor checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Rthere Distance warning function Important safety notes i Observe the "Important safety notes" section for driving safety systems (Y page 66). G WARNING The distance warning function does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering Thus, the distance warning function cannot provide a warning in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto Z Safety At speeds of up to approximately 44 mph (70 km/h), BAS PLUS can react to: 69 70 Driving safety systems Safety G WARNING The distance warning function cannot always clearly identify objects and complex traffic situations. In such cases, the distance warning function may: Rgive an unnecessary warning give a warning There is a risk of an accident. Always pay careful attention to the traffic situation and do not rely solely on the distance warning function. Rnot Function X To activate/deactivate: activate or deactivate the distance warning function in the on-board computer (Y page 245). If the distance warning function is not activated, the æ symbol appears in the assistance graphics display. The distance warning function can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically. Starting at a speed of around 4 mph (7 km/h), the distance warning function warns you if you rapidly approach a vehicle in front. An intermittent warning tone will then sound, and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action, provided it is safe to do so. Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause the system to display a warning. With the help of the radar sensor system, the distance warning function can detect obsta- cles that are in the path of your vehicle for an extended period of time. Up to a speed of around 44 mph (70 km/h), the distance warning function can also react to stationary obstacles, such as stopped or parked vehicles. If you approach an obstacle and the distance warning function detects a risk of a collision, the system will initially alert you both visually and acoustically. Autonomous braking function If the driver does not react to the distance warning signal in a critical situation, COLLISION PREVENTION ASSIST PLUS can assist with the autonomous braking function. The autonomous braking function: Rgives the driver more time to react to critical driving situations Rcan help the driver to avoid an accident or Rreduces the effects of an accident Vehicles without DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: R5 - 65 mph (7 - 105 km/h) for moving objects R5 - 31 mph (7 - 50 km/h) for stationary objects Vehicles with DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: R5 - 124 mph (7 - 200 km/h) for moving objects R5 - 31 mph (7 - 50 km/h) for stationary objects If the autonomous braking function requires a particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. Adaptive Brake Assist i Observe the "Important safety notes" section (Y page 66). Adaptive Brake Assist provides braking assistance in hazardous situations at speeds above 4 mph (7 km/h). It uses radar sensor technology to assess the traffic situation. G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situations. In such cases, Adaptive Brake Assist can: Rintervene unnecessarily intervene There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Terminate the intervention in a non-critical driving situation. Rnot G WARNING Adaptive Brake Assist does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering As a result, the Adaptive Brake Assist may not intervene in all critical conditions. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause Brake Assist to intervene. If adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. With the help of adaptive Brake Assist, the distance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. If adaptive Brake Assist detects a risk of collision with the vehicle in front, it calculates the braking force necessary to avoid a collision. If you apply the brakes forcefully, adap- tive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: Ryou release the brake pedal. Rthere is no longer any danger of a collision. Rno obstacle is detected in front of your vehicle. Adaptive Brake Assist is then deactivated. If adaptive Brake Assist demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. Up to a speed of approximately 155 mph (250 km/h), adaptive Brake Assist is capable of reacting to moving objects that have already been detected as such at least once over the period of observation. Up to a speed of approximately 44 mph (70 km/h), adaptive Brake Assist reacts to stationary obstacles. ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes" section (Y page 66). ESP® monitors driving stability and traction, i.e. power transmission between the tires and the road surface. If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking. Z 71 Safety Driving safety systems 72 Driving safety systems ETS/4ETS (Electronic Traction System) i Observe the "Important safety notes" sec- Safety tion (Y page 66). ETS traction control is part of ESP®. On vehicles with 4MATIC, 4ETS is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. In addition, more drive torque is transferred to the wheel or wheels with traction. Traction control remains active, even if you deactivate ESP®. Important safety notes i Observe the "Important safety notes" section (Y page 66). G WARNING If ESP® is malfunctioning, ESP® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop. ! If you test the parking brake using a brake dynamometer, switch the ignition off. Application of the brakes by ESP® may otherwise destroy the brake system. When towing the vehicle with the rear axle raised, observe the notes on ESP® (Y page 353). ESP® is deactivated if the warning lamp å in the instrument cluster lights up and: Rthe vehicle is moving Rthe ECO start/stop function is activated If the ÷ warning lamp lights up continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 288) and display messages which may be shown in the instrument cluster (Y page 251). Only use wheels with the recommended tire sizes. Only then will ESP® function properly. Characteristics of ESP® General information If the ÷ ESP warning lamp goes out before beginning the journey, ESP® is automatically active. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. If ESP® intervenes: Do not deactivate ESP® under any circumstances. X Only depress the accelerator pedal as far as necessary when pulling away. X Adapt your driving style to suit the prevailing road and weather conditions. X ECO start/stop function The ECO start/stop function switches the engine off automatically when the vehicle stops moving. The engine starts automatically when the driver wants to pull away again. ESP® remains in its previously selected status. Example: if ESP® was deactivated before the engine was switched off, ESP® remains deactivated when the engine is switched on again. Deactivating/activating ESP® Important safety notes i Observe the "Important safety notes" section (Y page 66). You can select between the following states of ESP®: RESP® RESP® is activated. is deactivated. G WARNING If you deactivate ESP®, ESP® no longer stabilizes the vehicle. There is an increased risk of skidding and an accident. Driving safety systems It may be best to deactivate ESP® in the following situations: Rwhen using snow chains deep snow Ron sand or gravel Activate ESP® as soon as the situations described above no longer apply. ESP® will otherwise not be able to stabilize the vehicle if the vehicle starts to skid or a wheel starts to spin. RPRE-SAFE® Brake is no longer available, it is also not activated if you brake firmly and ESP® intervenes. RESP® still provides support when you brake firmly. Rin Crosswind Assist ! Avoid spinning the driven wheels for an General information Strong crosswinds can cause your vehicle to deviate from a straight course. The crosswind driving assistance function integrated into ESP® significantly reduces these effects. ESP® intervenes automatically according to the direction and intensity of the crosswinds affecting your vehicle. ESP intervenes with stabilizing braking to assist you in keeping the vehicle in the lane. Crosswind Assist is active at vehicle speeds above 50 mph (80 km/h) when driving straight ahead or cornering gently. extended period with ESP® deactivated. You could otherwise damage the drivetrain. Deactivating/activating ESP® You can deactivate or activate ESP® via the on-board computer. X To deactivate: (Y page 72). The å ESP® OFF warning lamp in the instrument cluster lights up. X To activate: (Y page 72). The å ESP® OFF warning lamp in the instrument cluster goes out. Characteristics when ESP® is deactivated If ESP® is deactivated and one or more wheels start to spin, the ÷ ESP® warning lamp in the instrument cluster does not flash. In such situations, ESP® will not stabilize the vehicle. If you deactivate ESP®: RESP® no longer improves driving stability. driven wheels can spin. The spinning of the wheels results in a cutting action for better traction on loose surfaces. Rtraction control is still activated. RPRE-SAFE® is no longer available, nor is it activated if you brake firmly and ESP® intervenes. Rthe Important safety notes Crosswind Assist does not work if ESP® is deactivated or disabled because of a malfunction. EBD (electronic brake force distribution) General information EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. Important safety notes i Observe the "Important safety notes" section (Y page 66). G WARNING If EBD is malfunctioning, the rear wheels can lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have Z Safety Only deactivate ESP® in the situations described in the following. 73 74 Driving safety systems Safety the brake system checked at a qualified specialist workshop. Observe information regarding indicator and warning lamps (Y page 286) as well as display messages (Y page 254). ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 196) and hill start assist (Y page 160). PRE-SAFE® Brake General information i Pay attention to the important safety notes in the "Driving safety systems" section (Y page 66). PRE‑SAFE® Brake is only available for vehicles with the Driving Assistance package. For PRE-SAFE® Brake to assist you when driving, the radar sensor system and the camera system must be switched on and be operational. With the help of the radar sensor system and the camera system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. In addition, pedestrians in the path of your vehicle can be detected. PRE-SAFE® Brake detects pedestrians using typical characteristics such as the body contours and posture of a person standing upright. Observe the restrictions described in the "Important safety notes" section“ (Y page 74). PRE-SAFE® Brake can help you to minimize the risk of a collision with a vehicle ahead or a pedestrian, and reduce the effects of such a collision. If PRE-SAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. Important safety notes G WARNING PRE-SAFE® Brake will initially brake your vehicle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you brake yourself. Even after subsequent full application of the brakes a collision cannot always be avoided, particularly when approaching at too high a speed. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action, provided it is safe to do so. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. In these cases, PRE-SAFE® Brake may: Rgive an unnecessary warning and then brake the vehicle Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. Terminate the intervention in a non-critical driving situation. In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. PRE-SAFE® Brake can also brake the vehicle automatically under the following conditions: Rthe driver and front-passenger have their seat belts fastened and Rthe vehicle speed is between approximately 4 mph (7 km/h) and 124 mph (200 km/h) Driving safety systems Rstationary objects in the path of your vehicle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle G WARNING PRE-SAFE® Brake does not react: Rto small people, e.g. children animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering Rto As a result, PRE-SAFE® Brake may neither give warnings nor intervene in all critical situations.

Exterior lighting General notes For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, operation of the headlamps varies due to legal requirements and self-imposed obligations. Driving abroad Symmetrical low-beam headlamps Switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road from the country where the vehicle is registered. This prevents glare to oncoming traffic. When using symmetrical lights, the edge of the road is not lit as widely and as far ahead as normal. Have the headlamps converted at a qualified specialist workshop as close to the border as possible before driving in these countries. Asymmetrical low beam Have the headlamps converted back to asymmetrical low-beam headlamps at a qualified specialist workshop as soon as possible after crossing the border again. 1 W Left-hand standing lamps 2 X Right-hand standing lamps 3 T Parking lamps, license plate and instrument cluster lighting 4 à Automatic headlamp mode, control- led by the light sensor 5 L Low-beam/high-beam headlamps B R Rear fog lamp If you hear a warning tone when you leave the vehicle, the lights may still be switched on.

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions. i Read the information on qualified special- Climate control ist workshops (Y page 26). Overview of climate control systems Important safety notes Observe the settings recommended on the following pages. The windows could otherwise fog up. To prevent the windows from fogging up: Rswitch Rswitch briefly off climate control only briefly on air-recirculation mode only Rswitch on the cooling with air dehumidification function Rswitch on the defrost windshield function briefly, if required Climate control regulates the temperature and air humidity in the vehicle interior. The interior filter cleans the air, thus improving the interior climate. The "Cooling with air dehumidification" function is only available when the engine is running. Optimum climate control is only achieved with the side windows and roof closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 149). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 98). This will speed up the cooling process and the desired interior temperature will be reached more quickly. i The integrated filter filters out most par- ticles of dust and soot and completely filters out pollen. It also reduces gaseous pollutants and odors. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Maintenance Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet. i It is possible that the blower may be activated automatically 60 minutes after the SmartKey has been removed depending on various factors, e.g. the outside temperature. The vehicle is then ventilated for 30 minutes to dry the climate control system. Overview of climate control systems 139 : To set the temperature, left (Y page 145) ; To set the air distribution (Y page 146) = To set the airflow (Y page 146) To switch off climate control (Y page 142) ?

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions. i Read the information on qualified specialist workshops (Y page 26). Notes on breaking-in a new vehicle Important safety notes The sensor system of some driving and driving safety systems adjusts automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in procedure. New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. RDo not manually shift to a lower gear to brake the vehicle. RTry to avoid depressing the accelerator pedal beyond the point of resistance (kickdown). After 1000 miles (1500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced. Always observe the respective speed limits. Driving Important safety notes G WARNING Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal. The operating and road safety of the vehicle is jeopardized. There is a risk of an accident. Make sure that all objects in the vehicle are stowed correctly, and that they cannot enter the driver's footwell. Install the floormats securely and as specified in order to ensure sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on top of one another. G WARNING The first 1000 miles (1500 km) The more you look after the engine when it is new, the more satisfied you will be with its performance in the future. RYou should therefore drive at varying vehicle and engine speeds for the first 1000 miles (1500 km). RAvoid heavy loads, e.g. driving at full throttle, during this period. RWhen changing gears manually, change up in good time, before the tachometer needle reaches Ô of the way to the red area of the tachometer. Unsuitable footwear can hinder correct usage of the pedals, e.g.: Rshoes with thick soles with high heels Rslippers There is a risk of an accident. Wear suitable footwear to ensure correct usage of the pedals. Rshoes G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake Driving G WARNING If the parking brake has not been fully released when driving, the parking brake can: Roverheat and cause a fire its hold function. There is a risk of fire and an accident. Release the parking brake fully before driving off. Rlose ! Warm up the engine quickly. Do not use the engine's full performance until it has reached operating temperature. Only shift the automatic transmission to the desired drive position when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. You could otherwise damage the drive train. SmartKey positions SmartKey i The SmartKey can be turned in the igni- tion lock even if it is not the correct SmartKey for the vehicle. The ignition is not switched on. The engine cannot be started. Vehicles with AIRPANEL: you can open the shutters in the radiator trim, by turning the key to position 2 in the ignition lock. After approximately 120 seconds the shutters open automatically. Further information on opening and cleaning the shutters (Y page 334). Start/Stop button General notes A check which periodically establishes a radio connection between the vehicle and the SmartKey determines whether a valid SmartKey is in the vehicle. This occurs, for example, when starting the engine. To start the vehicle without actively using the SmartKey: Rthe Start/Stop button must be inserted in the ignition lock. Rthe SmartKey must be in the vehicle. Rthe vehicle must not be locked with the SmartKey or KEYLESS-GO (Y page 81). Pressing the Start/Stop button several times in succession corresponds to the different SmartKey positions in the ignition lock. This is only the case if you are not depressing the brake pedal. If you depress the brake pedal and press the Start/Stop button, the engine starts immediately.

Driving and parking X Driving tips General driving tips Important safety notes G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving. G WARNING If you operate mobile communication equipment while driving, you will be distracted from traffic conditions. You could also lose control of the vehicle. There is a risk of an accident. Only operate this equipment when the vehicle is stationary. Observe the legal requirements for the country in which you are driving. Some jurisdictions prohibit the driver from using a mobile phone while driving a vehicle. If you make a call while driving, always use hands-free mode. Only operate the telephone when the traffic situation permits. If you are unsure, pull over to a safe location and stop before operating the telephone. Bear in mind that at a speed of only 30 mph (approximately 50 km/h), the vehicle covers a distance of 44 ft (approximately 14 m) per second. Drive sensibly – save fuel Observe the following tips to save fuel: The tires should always be inflated to the recommended tire pressure. X Remove unnecessary loads. X Remove roof racks when they are not needed. X Warm up the engine at low engine speeds. X Avoid frequent acceleration or braking. X Have all maintenance work carried out as indicated by the service intervals in the Maintenance Booklet or by the service interval display. X Fuel consumption also increases when driving in cold weather, in stop-start traffic and in hilly terrain. Drinking and driving G WARNING Drinking and driving and/or taking drugs and driving are very dangerous combinations. Even a small amount of alcohol or drugs can affect your reflexes, perceptions and judgment. The possibility of a serious or even fatal accident is greatly increased when you drink or take drugs and drive. Do not drink or take drugs and drive or allow anyone to drive who has been drinking or taking drugs. Emission control G WARNING Combustion engines emit poisonous exhaust gases such as carbon monoxide. Inhaling these exhaust gases leads to poisoning. There is a risk of fatal injury. Therefore never leave the engine running in enclosed spaces without sufficient ventilation. Certain engine systems are designed to keep the level of poisonous components in exhaust fumes within legal limits. These systems only work at peak efficiency if they are serviced exactly in accordance with the manufacturer's specifications. For this reason, all work on the engine must be carried out by qualified and authorized MercedesBenz technicians. The engine settings must not be changed under any circumstances. Furthermore, all specific service work must be carried out at regular intervals and in accordance with the Mercedes-Benz service requirements. Details can be found in the Maintenance Booklet. ECO display range ?. The 8 warning lamp in the instrument cluster also lights up (Y page 291). The ECO display consists of three sections, with an inner and outer area. The sections correspond to the following three categories: : Acceleration (evaluation of all acceleration processes): Rthe outer area fills up and the inner area lights up green: moderate acceleration, especially at higher speeds Rthe outer area empties and the inner area is gray: sporty acceleration ; The ECO display shows you how economical your driving style is. The ECO display assists you in achieving the most economical driving style for the selected settings and prevailing conditions. Your driving style can significantly influence the vehicle's consumption. Coasting (evaluation of all deceleration processes): Rthe outer area fills up and the inner area lights up green: anticipatory driving, keeping your distance and early release of the accelerator. The vehicle can coast without use of the brakes. Rthe outer area empties and the inner area is gray: frequent heavy braking = Constant (continuous evaluation over the entire journey): Rthe : ; = ? Acceleration Coasting Constant Additional range achieved Range ? is shown under Bonus fr. Start and represents the additional range achieved since the beginning of the journey as a result of an adapted driving style. If the fuel level has dropped into the reserve range, the Reserve Fuel message is shown in the multifunction display instead of outer area fills up and the inner area lights up green: constant speed and avoidance of unnecessary acceleration and deceleration Rthe outer area empties and the inner area is gray: fluctuations in speed The three inner areas display the current driving style and light up green as a result of a particularly economical driving style. Depending on the driving situation, up to two areas may light up simultaneously. Z 179 Driving and parking Driving tips Driving and parking 180 Driving tips At the beginning of the journey, the three outer areas are empty and fill up as a result of economical driving. A higher level indicates a more economical driving style. If the three outer areas are completely filled at the same time, the driver has adopted the most economical driving style for the selected settings and prevailing conditions. The ECO display border lights up. The ECO display does not indicate the actual fuel consumption. The additionally achieved range displayed under Bonus fr. Start does not indicate a fixed consumption reduction. In addition to driving style, the actual consumption is affected by other factors, such as: Rload Rtire pressure start Rchoice of route Relectrical consumers switched on These factors are not included in the ECO display. An economical driving style specially requires driving at moderate engine speeds. Achieving a higher value in the categories "Acceleration" and "Constant": Rcold Robserve the gearshift recommendations. Rdrive the vehicle in drive program E (vehicles with the AGILITY SELECT switch) On long journeys at a constant speed, e.g. on the highway, only the outer area for "constant" will change. The ECO display summarizes the driving style from the start of the journey to its completion. Therefore, there are more marked changes in the outer areas at the start of a journey. On longer journeys, there are fewer changes. For more marked changes, perform a manual rest (Y page 237). For further information on the ECO display, see (Y page 236). Braking Important safety notes G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. There is an increased danger of skidding and accidents. Do not shift down for additional engine braking on a slippery road surface. Downhill gradients ! On long and steep gradients, you must reduce the load on the brakes by shifting early to a lower gear. This allows you to take advantage of the engine braking effect and helps avoid overheating and excessive wear of the brakes. When you take advantage of the engine braking effect, a drive wheel may not turn for some time, e.g. on a slippery road surface. This could cause damage to the drive train. This type of damage is not covered by the Mercedes-Benz warranty. Heavy and light loads G WARNING If you rest your foot on the brake pedal while driving, the braking system can overheat. This increases the stopping distance and can even cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Never depress the brake pedal and the accelerator pedal at the same time. ! Depressing the brake pedal constantly results in excessive and premature wear to the brake pads. If the brakes have been subjected to a heavy load, do not stop the vehicle immediately. Drive on for a short while. This allows the airflow to cool the brakes more quickly. Wet roads If you have driven for a long time in heavy rain without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after the vehicle has been washed or driven through deep water. You have to depress the brake pedal more firmly. Maintain a greater distance from the vehicle in front. After driving on a wet road or having the vehicle washed, brake firmly while paying attention to the traffic conditions. This will warm up the brake discs, thereby drying them more quickly and protecting them against corrosion. Limited braking performance on salttreated roads If you drive on salted roads, a layer of salt residue may form on the brake discs and brake pads. This can result in a significantly longer braking distance. RIn order to prevent any salt build-up, apply the brakes occasionally while paying attention to the traffic conditions. RCarefully depress the brake pedal and the beginning and end of a journey. RMaintain a greater distance to the vehicle ahead. Servicing the brakes ! If the red brake warning lamp lights up in the instrument cluster and you hear a warning tone while the engine is running, the brake fluid level may be too low. Observe additional warning messages in the multifunction display. The brake fluid level may be too low due to brake pad wear or leaking brake lines. Have the brake system checked immediately. This work should be carried out at a qualified specialist workshop. ! A function or performance test should only be carried out on a 2-axle dynamom- eter. If you wish to operate the vehicle on such a dynamometer, please consult an authorized Mercedes-Benz Center in advance. You could otherwise damage the drive train or the brake system. ! The ESP® system operates automatically. The engine and the ignition must therefore be switched off (the SmartKey must be in position 0 or 1 in the ignition lock or the Start/Stop button must be in position 0 or 1) if the electric parking brake is tested on a brake dynamometer. Braking triggered automatically by ESP® may cause severe damage to the brake system. All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. Consult a qualified specialist workshop to arrange this. Have brake pads installed and brake fluid replaced at a qualified specialist workshop. If the brake system has only been subject to moderate loads, you should test the functionality of your brakes at regular intervals. Information on BAS (Brake Assist) (Y page 67) and BAS PLUS (Brake Assist PLUS) (Y page 67). For safety reasons, Mercedes-Benz recommends only installing the following brake disks and brake pads/linings: Rbrake disks that have been approved by Mercedes-Benz Rbrake pads/linings that have been approved by Mercedes-Benz or that are of an equivalent standard of quality Other brake disks or brake pads/linings can compromise the safety of your vehicle. Always replace all brake disks and brake pads/linings on an axle at the same time. Always install new brake pads/linings when replacing brake disks. The vehicle is equipped with lightweight brake disks to which the wheel assembly with rim and threaded connection is matched. Z 181 Driving and parking Driving tips Driving and parking 182 Driving tips The use of brake disks other than those approved by Mercedes-Benz can change the track width and is subject to approval, if applicable. Shock-type loads when handling the brake disks, such as when changing wheels, can lead to a reduction in comfort when driving with lightweight brake disks. Avoid shocktype loads on the lightweight brake disks, particularly on the brake plate. Mercedes-Benz recommends that you only use brake fluid that has been specially approved for your vehicle by Mercedes-Benz, or which corresponds to an equivalent quality standard. Brake fluid which has not been approved for Mercedes-Benz vehicles or which is not of an equivalent quality could affect your vehicle's operating safety. Driving on wet roads Hydroplaning If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if: Ryou drive at low speeds. tires have adequate tread depth. For this reason, in the event of heavy rain or in conditions in which hydroplaning may occur, you must drive in the following manner: Rthe Rlower your speed. ruts. Ravoid sudden steering movements. Rbrake carefully. Ravoid Driving on flooded roads ! Bear in mind that vehicles traveling in front or in the opposite direction create waves. This may cause the maximum permissible water depth to be exceeded. Failure to observe these notes may result in damage to the engine, electrical systems and transmission. If you have to drive on stretches of road on which water has collected, please bear in mind that: Rthe water level, in the case of still water, may not exceed a maximum point of the lower edge of the vehicle body Ryou should drive no faster than at a walking pace Winter driving G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. There is an increased danger of skidding and accidents. Do not shift down for additional engine braking on a slippery road surface. G DANGER If the exhaust pipe is blocked or adequate ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle becomes trapped in snow. There is a risk of fatal injury. If you leave the engine or the auxiliary heating running, make sure the exhaust pipe and area around the vehicle are clear of snow. To ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not facing into the wind. Have your vehicle winter-proofed at a qualified specialist workshop at the onset of winter. Drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking maneuvers. Do not use the cruise control or DISTRONIC PLUS. If the vehicle threatens to skid or cannot be stopped when moving at low speed: X Shift the transmission to position N. Driving systems Driving systems Mercedes-Benz Intelligent Drive Mercedes-Benz Intelligent Drive stands for innovative driver assistance and safety systems which enhance comfort and support the driver in critical situations. With these intelligent co-ordinated systems Mercedes-Benz has set a milestone on the path towards autonomous driving. Mercedes-Benz Intelligent Drive embraces all elements of active and passive safety in one well thought out system – for the safety of the vehicle occupants and that of other road users. Further information on driving safety systems (Y page 66). Cruise control General notes Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. Change into a lower gear in good time on long and steep downhill gradients. This is especially important if the vehicle is laden. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. Use cruise control only if road and traffic conditions make it appropriate to maintain a steady speed for a prolonged period. You can store any road speed above 20 mph (30 km/h). Important safety notes If you fail to adapt your driving style, cruise control can neither reduce the risk of an accident nor override the laws of physics. Cruise control cannot take into account the road, traffic and weather conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. Do not use cruise control: Rin road and traffic conditions which do not allow you to maintain a constant speed e.g. in heavy traffic or on winding roads Ron slippery road surfaces. Braking or accelerating could cause the drive wheels to lose traction and the vehicle could then skid Rwhen there is poor visibility, e.g. due to fog, heavy rain or snow If there is a change of drivers, advise the new driver of the speed stored. Z Driving and parking The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. Changes in the outside temperature are displayed after a short delay. Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges. The vehicle could skid if you fail to adapt your driving style. Always adapt your driving style and drive at a speed to suit the prevailing weather conditions. You should pay special attention to road conditions when temperatures are around freezing point. For more information on driving with snow chains, see (Y page 361). For more information on driving with summer tires, see (Y page 360).

DISTRONIC PLUS General notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. Vehicles are detected with the aid of the radar sensor system. DISTRONIC PLUS brakes automatically so that the set speed is not exceeded. Z Driving and parking Setting a speed Driving and parking 186 Driving systems Change into a lower gear in good time on long and steep downhill gradients. This is especially important if the vehicle is laden. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If DISTRONIC PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. DISTRONIC PLUS cannot prevent a collision without your intervention. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. Brake immediately in order to increase the distance to the vehicle in front or take evasive action provided it is safe to do so. DISTRONIC PLUS operates in range between 0 mph (0 km/h) and 120 mph (200 km/h). Do not use DISTRONIC PLUS while driving on roads with steep gradients. As DISTRONIC PLUS transmits radar waves, it can resemble the radar detectors of the responsible authorities.

Tips for driving with DISTRONIC PLUS General notes Pay particular attention in the following traffic situations: RCornering, going into and coming out of a bend RVehicles traveling on a different line ROther vehicles changing lanes RNarrow vehicles Driving systems RObstructions and stationary vehicles vehicles In such situations, brake if necessary. DISTRONIC PLUS is then deactivated. 193 Other vehicles changing lanes Cornering, going into and coming out of a bend DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. Narrow vehicles The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late. Vehicles traveling on a different line DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road, because of its narrow width. The distance to the vehicle in front will be too short. Obstructions and stationary vehicles DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short. DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the Z Driving and parking RCrossing 194 Driving systems detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Driving and parking Crossing vehicles DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot General notes DISTRONIC PLUS with Steering Assist and Stop&Go Pilot aids you in keeping the vehicle in the center of the driving lane by means of moderate steering interventions in a speed range from 0 - 125 mph (0 - 200 km/h). It monitors the area in front of your vehicle by means of camera system : at the top of the windshield. At speeds of more than 37 mph (60 km/h) Steering Assist focuses on clear lane markings (left and right). In a speed range from 0 - 37 mph (0 - 60 km/h) Stop&Go Pilot focuses on the vehicle in front, taking into account lane markings, e.g. when following vehicles in a traffic jam. If these conditions are not present, Steering Assist and Stop&Go Pilot cannot provide assistance. DISTRONIC PLUS must be active in order for the function to be available. Important safety notes If you fail to adapt your driving style, DISTRONIC PLUS with Steering Assist and Stop&Go Pilot can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot does not detect road and traffic conditions and does not detect all road users. If you are following a vehicle which is driving towards the edge of the road, your vehicle could come into contact with the curb or other road boundaries. In the case of deviations in road markings, beware of other road users, e.g. cyclists that are in the direct vicinity of your vehicle. Obstacles such as building site huts on the lane or projecting out into the lane are not detected. An inappropriate steering intervention, e.g. after intentionally driving over a lane marking, can be corrected at any time if you steer slightly in the opposite direction. DISTRONIC PLUS with Steering Assist and Stop&Go Pilot cannot continuously keep your vehicle in lane. In some cases, the steering intervention is not sufficient to bring the vehi- cle back to the lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray Rthere is glare, e.g. from oncoming traffic, the sun or reflections (e.g. when the road surface is wet) Rthe windshield is dirty, fogged up, damaged or covered, for instance by a sticker, in the vicinity of the camera Rthere are no, several or unclear lane markings for a lane, e.g. in areas with road construction work Rthe lane markings are worn away, dark or covered up, e.g. by dirt or snow Rthe distance to the vehicle in front is too small and the lane markings thus cannot be detected Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge Rthe road is narrow and winding Rthere are strong shadows cast on the road The system is switched to passive and no longer assists you by performing steering interventions if: Ryou actively change lane Ryou switch on the turn signal Rtake your hands off the steering wheel or do not steer for a prolonged period of time i After you have finished changing lanes, Pay attention also to the important safety notes for DISTRONIC PLUS (Y page 186). The steering interventions are carried out with a limited steering moment. The system requires the driver to keep his hands on the steering wheel and to steer himself. If you do not steer yourself or if take your hands off the steering wheel for a prolonged period of time, the system will first alert you with a visual warning. A steering wheel symbol appears in the multifunction display. If you have still not started to steer and have not taken hold of the steering wheel after five seconds at the latest, a warning tone also sounds to remind you to take control of the vehicle.

Allround level control ensures the best possible suspension and constant ground clearance, even with a laden vehicle. When you drive fast, the vehicle is lowered automatically to improve driving safety and to reduce fuel consumption. There is also the option to manually adjust the vehicle level. AIRMATIC consists of level setting, level control and the Adaptive Damping System ADS. The vehicle level can be set using the AGILITY SELECT switch (Y page 167) or the level button (Y page 198). The setting always corresponds to the last selected function. Important safety notes G WARNING When the vehicle is being lowered, people could become trapped if their limbs are between the vehicle body and the wheels or underneath the vehicle. There is a risk of injury. Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches when the vehicle is being lowered.

When driving at speeds below 50 mph (80 km/h) the vehicle is raised again. 4MATIC (permanent four-wheel drive) 4MATIC ensures that all four wheels are permanently driven. Together with ESP®, it improves the traction of your vehicle whenever a drive wheel spins due to insufficient grip. If you fail to adapt your driving style, 4MATIC can neither reduce the risk of accident nor override the laws of physics. 4MATIC cannot take account of road, weather and traffic conditions. 4MATIC is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. If a drive wheel spins due to insufficient grip: ROnly depress the accelerator pedal as far as necessary when pulling away. less when driving. RAccelerate ! Never tow the vehicle with one axle raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground. i In wintry driving conditions, the maximum effect of 4MATIC can only be achieved if you use winter tires (M+S tires), with snow chains if necessary. PARKTRONIC Important safety notes PARKTRONIC is an electronic parking aid with ultrasonic sensors. It monitors the area around your vehicle using six sensors in the front bumper and six sensors in the rear bumper. PARKTRONIC indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is only an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. When maneuvering, parking or pulling out of a parking space, make sure that there are no persons, animals or objects in the area in which you are maneuvering. ! When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects. The sensors may not detect snow and other objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic car wash, the compressed-air brakes on a truck or a pneumatic drill could cause PARKTRONIC to malfunction. PARKTRONIC may not function correctly on uneven terrain. PARKTRONIC is activated automatically when you: Rswitch on the ignition the transmission to position D, R or N PARKTRONIC is deactivated at speeds above 11 mph (18 km/h). It is reactivated at lower speeds.

Active Parking Assist General notes Active Parking Assist is an electronic parking aid with ultrasound. It measures the road on both sides of the vehicle. A parking symbol indicates a suitable parking space. Active steering intervention and brake application can assist you during parking and when exiting a parking space. You may also use PARKTRONIC (Y page 199). Important safety notes Active Parking Assist is merely an aid. It is not a replacement for your attention to your immediate surroundings. You are always responsible for safe maneuvering, parking and exiting a parking space. Make sure that no persons, animals or objects are in the maneuvering range. When PARKTRONIC is switched off, Active Parking Assist is also unavailable. G WARNING While parking or pulling out of a parking space, the vehicle swings out and can drive onto areas of the oncoming lane. This could result in a collision with another road user. There is a risk of an accident. Pay attention to other road users. Stop the vehicle if necessary or cancel the Active Parking Assist parking procedure. ! If unavoidable, you should drive over obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires. Active Parking Assist may possibly indicate parking spaces which are not suitable for parking, for example: Rwhere parking or stopping is prohibited Rin front of driveways or entrances and exits Ron unsuitable surfaces Driving systems ROn narrow roads, drive as close to the park- ing space as possible. spaces that are littered or overgrown might be identified or measured incorrectly. RParking spaces that are partially occupied by trailer drawbars might not be identified as such or be measured incorrectly. RSnowfall or heavy rain may lead to a parking space being measured inaccurately. RPay attention to the PARKTRONIC (Y page 200) warning messages during the parking procedure. RYou can intervene in the steering procedure to correct it at any time. Active Parking Assist will then be canceled. RWhen transporting a load which protrudes from your vehicle, you should not use Active Parking Assist. RNever use Active Parking Assist when snow chains are installed. RMake sure that the tire pressures are always correct. This has a direct influence on the parking characteristics of the vehicle. Use Active Parking Assist for parking spaces: RParking Rparallel or at right angles to the direction of travel are on straight roads, not bends Rthat are on the same level as the road, e.g. not on the pavement Rthat G WARNING If there are objects above the detection range: RActive Park Assist may steer too early vehicle may not stop in front of these objects.

Z Driving and parking Parking tips: 203 Driving and parking 204 Driving systems : Detected parking space on the left ; Parking symbol = Detected parking space on the right Active Parking Assist is switched on automatically when driving forwards. The system is operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the system independently locates and measures parking spaces on both sides of the vehicle. Active Parking Assist will only detect parking spaces: Rparallel or at right angles to the direction of travel are parallel to the direction of travel and at least 59 in (1.5 m) wide Rthat are parallel to the direction of travel and at least 39.5 in (1.0 m) longer than your vehicle Rthat are at right angles to the direction of travel and at least 39.5 in (1.0 m) wider than your vehicle Rthat er's side are displayed as soon as the turn signal on the driver's side is activated. When parking on the driver's side, this must remain switched on until you acknowledge the use of Active Parking Assist by pressing the a button on the multifunction steering wheel. The system automatically determines whether the parking space is parallel or at right angles to the direction of travel. A parking space is displayed while you are driving past it, and until you are approximately 50 ft (15 m) away from it. Parking G WARNING If you leave the vehicle when it is only being braked by Active Parking Assist it could roll away if: Rthere is a malfunction in the system or in the voltage supply. Rthe electrical system in the engine compartment, the battery or the fuses have been tampered with. Rthe battery is disconnected. Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant. There is a risk of an accident. Before leaving the vehicle, always secure it against rolling away. i When PARKTRONIC detects obstacles, Active Parking Assist brakes automatically during the parking process. You are responsible for braking in good time. i Note that Active Parking Assist cannot measure the length of a parking space if it is at right angles to the direction of travel. You will need to judge whether your vehicle will fit in the parking space. When driving at speeds below 19 mph (30 km/h), you will see the parking symbol as a status indicator in the instrument cluster. When a parking space has been detected, an arrow towards the right or the left also appears. By default, Active Parking Assist only displays parking spaces on the frontpassenger side.

Active Parking Assist no longer supports you with steering interventions and brake applications. When Active Parking Assist is finished, you must steer and brake again yourself. PARKTRONIC is still available. Parking tips: RThe way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. It may be the case that Active Parking Assist guides you too far into a parking space, or not far enough into it. In some cases, it may also lead you across or onto the curb. If necessary, you should cancel the parking procedure with Active Parking Assist. RYou can also select preselect transmission position D. The vehicle redirects and does not drive as far into the parking space. Should the transmission change take place too early, the parking procedure will be canceled. A sensible parking position can no longer be achieved from this position. Exiting a parking space In order that Active Parking Assist can support you when you exit the parking space: Rthe border of the parking space must be high enough at the front and the rear. A curb is too small, for example. Rthe border of the parking space must not be too wide, as the position of the vehicle must not exceed an angle of 45° to the starting Z 205 Driving and parking Driving systems Driving systems Driving and parking 206 position as it is maneuvering into the parking space.

It is active in the 37 mph (60 km/h) to 125 mph (200 km/h) range. If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests taking a break. ATTENTION ASSIST is reset when you continue your journey and starts assessing your tiredness again if: Ryou switch off the engine. take off your seat belt and open the driver's door, e.g. for a change of drivers or to take a break. Ryou Displaying the attention level Important safety notes ATTENTION ASSIST is only an aid to the driver. It might not always recognize fatigue or increasing inattentiveness in time or fail to recognize them at all. The system is not a substitute for a well-rested and attentive driver. The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Rif the length of the journey is less than approximately 30 minutes Rif the road condition is poor, e.g. if the surface is uneven or if there are potholes Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration Rif you are predominantly driving slower than 37 mph (60 km/h) or faster than 125 mph (200 km/h) Rif you are driving with the active Steer Assist of DISTRONIC PLUS Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed You can have current status information displayed in the assistance menu (Y page 244) of the on-board computer. X Select the Assistance display for Attention Assist using the on-board computer (Y page 243). The following information is displayed: Rlength of the journey since the last break. attention level determined by ATTENTION ASSIST (Attention Attention Level), Level displayed in a bar display in five levels from high to low. RIf ATTENTION ASSIST is unable to calculate the attention level and cannot output a warning, the System Suspended message appears. The bar display then changes the display, e.g. if you are driving at a speed below 37 mph (60 km/h) or above 124 mph (200 km/h). Rthe Driving systems X Activate ATTENTION ASSIST using the onboard computer (Y page 246). The system determines the attention level of the driver depending on the setting selected: Selection Standard Standard: the sensitivity with which the system determines the attention level is set to normal. Selection Sensitive Sensitive: the sensitivity is set higher. The attention level detected by Attention Assist is adapted accordingly and the driver is warned earlier. When ATTENTION ASSIST is deactivated, the é symbol appears in the multifunction display in the assistance graphic display. When ATTENTION ASSIST has been deactivated, it is automatically reactivated after the engine has been stopped. The sensitivity selected corresponds to the last selection activated (standard/sensitive). Warning in the multifunction display If fatigue or increasing lapses in concentration are detected, a warning appears in the multifunction display: ATTENTION ASSIST Take a Break!. Break! In addition to the message shown in the multifunction display, you will then hear a warning tone. X If necessary, take a break. X Confirm the message by pressing the a button on the steering wheel. On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break and ATTENTION ASSIST still detects increasing lapses in concentration, you will be warned again after 15 minutes at the earliest. This will only happen if ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration. If a warning is output in the multifunction display, a service station search is performed in COMAND. You can select a service station and navigation to this service station will then begin. This function can be activated and deactivated in COMAND. Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 217) and Lane Keeping Assist (Y page 219). Blind Spot Assist General notes Blind Spot Assist monitors the areas on either side of the vehicle that are not visible to the driver with two lateral, rear-facing radar sensors. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible warning. Blind Spot Assist supports you from a speed of approximately 20 mph (30 km/h). Important safety notes G WARNING Blind Spot Assist does not react to: Rvehicles overtaken too closely on the side, placing them in the blind spot area Rvehicles which approach with a large speed differential and overtake your vehicle As a result, Blind Spot Assist may not give warnings in such situations. There is a risk of an accident. Always observe the traffic conditions carefully, and maintain a safe lateral distance. Blind Spot Assist is only an aid. It may fail to detect some vehicles and is no substitute for attentive driving. Always ensure that there is sufficient distance to the side for other road users and obstacles.

Active Z 219 Driving and parking Driving systems Driving and parking 220 Driving systems Lane Keeping Assist detects lane markings on the road and can warn you before you leave your lane unintentionally. This function is available in the range between 40 mph and 120 mph (60 km/h and 200 km/h). A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds. Important safety notes G WARNING Lane Keeping Assist may not always clearly recognize lane markings. In this case, Lane Keeping Assist may: Rgive an unnecessary warning give a warning There is a risk of an accident. Always pay particular attention to the traffic situation and stay in lane, in particular if warned by Lane Keeping Assist. Rnot G WARNING The Lane Keeping Assist warning does not return the vehicle to the original lane. There is a risk of an accident. You should always steer, brake or accelerate yourself, in particular if warned by Lane Keeping Assist. If you fail to adapt your driving style, Lane Keeping Assist can neither reduce the risk of an accident nor override the laws of physics. Lane Keeping Assist cannot take into account the road, traffic and weather conditions. Lane Keeping Assist is merely an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. The Lane Keeping Assist does not keep the vehicle in the lane. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray Rthere is glare, e.g. from oncoming traffic, the sun or reflections (e.g. when the road surface is wet) Rthe windshield is dirty, fogged up, damaged or covered, for instance by a sticker, in the vicinity of the camera Rthere are no, several or unclear lane markings for a lane, e.g. in areas with road construction work Rthe lane markings are worn away, dark or covered up, e.g. by dirt or snow Rthe distance to the vehicle in front is too small and the lane markings thus cannot be detected Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge Rthe road is narrow and winding Rthere are strong shadows cast on the road Switching on Lane Keeping Assist X Press button ;.

Driving Assistance PLUS package General notes The Active Driving Assistance PLUS package consists of DISTRONIC PLUS (Y page 185), Active Blind Spot Assist (Y page 221) and Active Lane Keeping Assist (Y page 224). Active Blind Spot Assist General notes Active Blind Spot Assist uses a radar sensor system, pointed toward the rear of the vehicle, to monitor the area to the sides of the vehicle which the driver is unable to see. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible warning. If a risk of lateral collision is detected, corrective braking may help you avoid a collision. Active Blind Spot Assist evaluates the free space in the direction of travel and to the side before making a course-correcting brake application. For this, Active Blind Spot Assist uses radar sensors which are pointed in the direction of travel. Active Blind Spot Assist supports you from a speed of approximately 20 mph (30 km/h). Important safety notes Active Blind Spot Assist is only an aid and is not a substitute for attentive driving.

Warning display : Warning display Active Blind Spot Assist is not operational at speeds below approximately 20 mph (30 km/h). Vehicles in the monitoring range are then not indicated. If a vehicle is detected within the blind spot monitoring range at speeds above 20 mph (30 km/h), warning lamp : on the corresponding side lights up red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12 km/h). If you select the reverse gear, Active Blind Spot Assist is not operational. When Active Blind Spot Assist is activated, gray radar waves propagating backwards appear next to the vehicle in the assistance display in the multifunction display. Above a speed of 20 mph (30 km/h), the color of the radar waves in the assistance display changes to green ;. Active Blind Spot Assist is then ready for use. Visual and acoustic collision warning If you switch on the turn signals to change lanes and a vehicle is detected in the side monitoring range, you receive a visual and acoustic collision warning. You will then hear a double warning tone and red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Course-correcting brake application If Active Blind Spot Assist detects a risk of a lateral collision in the monitoring range, a course-correcting brake application is carried out. This is meant to assist you in avoiding a collision. G WARNING A course-correcting brake application cannot always prevent a collision. There is a risk of an accident. Always steer, brake or accelerate yourself, especially if Active Blind Spot Assist warns you or makes a course-correcting brake appliZ Driving and parking Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles at the inner edge of your lane. Due to the nature of the system: 223 224 Driving systems Driving and parking cation. Always maintain a safe distance at the sides. Switching on Active Blind Spot Assist X Make sure that Active Blind Spot Assist is activated in the on-board computer (Y page 246). X Turn the SmartKey to position 2 in the ignition lock. Warning lamps : in the exterior mirrors light up red for approximately 1.5 seconds. Gray radar waves propagating backwards appear next to the vehicle in the assistance display in the multifunction display. Active Lane Keeping Assist If a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and a dual warning tone sounds. In addition, display ; underlining the danger of a side collision appears in the multifunction display. In very rare cases, the system may make an inappropriate brake application. A coursecorrecting brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate. The course-correcting brake application is available in the speed range between 20 mph (30 km/h) and 120 mph (200 km/h). Either no braking application, or a coursecorrecting brake application adapted to the driving situation occurs if: Rthere are vehicles or obstacles, e.g. crash barriers, located on both sides of your vehicle. Ra vehicle approaches you too closely at the side. Ryou have adopted a sporty driving style with high cornering speeds. Ryou clearly brake or accelerate. Ra driving safety system intervenes, e.g. ESP® or PRE-SAFE® Brake. RESP® is switched off. Ra loss of tire pressure or a defective tire is detected. General notes Active Lane Keeping Assist monitors the area in front of your vehicle by means of camera system : at the top of the windshield. Various different areas to the front, rear and side of your vehicle are also monitored with the aid of the radar sensor system. Active Lane Keeping Assist detects lane markings on the road and can warn you before you leave your lane unintentionally. If you do not react to the warning, a lane-correcting application of the brakes can bring the vehicle back into the original lane. If you select km in the Display Unit Speed-/Odometer: function on the on-board computer (Y page 248), Active Lane Keeping Assist is activated starting at a speed of 60 km/h. If the miles display unit is selected, the assistance range begins at 40 mph. Driving systems G WARNING Active Lane Keeping Assist cannot always clearly detect lane markings. In such cases, Active Lane Keeping Assist can: Rgive an unnecessary warning and then make a course-correcting brake application to the vehicle Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and keep within the lane, especially if Active Lane Keeping Assist alerts you. Terminate the intervention in a non-critical driving situation. The system may be impaired or may not function if: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray Rthere is glare, e.g. from oncoming traffic, the sun or reflections (e.g. when the road surface is wet) Rthe windshield is dirty, fogged up, damaged or covered, for instance by a sticker, in the vicinity of the camera Rthe radar sensors in the front or rear bumpers or the radiator grill are dirty, e.g. obscured by snow Rthere are no, several or unclear lane markings for a lane, e.g. in areas with road construction work Rthe lane markings are worn away, dark or covered up, e.g. by dirt or snow Rthe distance to the vehicle in front is too small and the lane markings thus cannot be detected Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge Rthe road is narrow and winding Rthere are strong shadows cast on the road If no vehicle is detected in the adjacent lane and there are broken lane markings detected, no lane-correcting brake application is made. Warning vibration in the steering wheel A warning may be given if a front wheel passes over a lane marking. It will warn you by means of intermittent vibration in the steering wheel for up to 1.5 seconds. Lane-correcting brake application If you leave your lane, under certain circumstances the vehicle will brake briefly on one side. This is meant to assist you in bringing the vehicle back to the original lane. G WARNING A lane-correcting brake application cannot always bring the vehicle back into the original lane. There is a risk of an accident. Always steer, brake or accelerate yourself, especially if Active Lane Keeping Assist warns you or makes a lane-correcting brake application. Z Driving and parking Important safety notes If you fail to adapt your driving style, Active Lane Keeping Assist can neither reduce the risk of accident nor override the laws of physics. Active Lane Keeping Assist cannot take account of road and weather conditions. It may not recognize traffic situations. Active Lane Keeping Assist is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in your lane. Active Lane Keeping Assist cannot continuously keep your vehicle in its lane. 225 226 Driving systems Driving and parking Ryou have adopted a sporty driving style with If a lane-correcting brake application occurs, display : appears in the multifunction display.

MOExtended tires (tires with run-flat properties) General notes With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires. The affected tire must not show any clearly visible damage. You can recognize MOExtended tires by the MOExtended marking which appears on the sidewall of the tire. You will find this marking next to the tire size designation, the loadbearing capacity and the speed index (Y page 375). MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor. If the pressure loss warning message appears in the multifunction display: RObserve the instructions in the display messages (Y page 277). RCheck the tire for damage. RIf driving on, observe the following notes. The maximum driving distance is approximately 50 miles (80 km) when the vehicle is partially laden and approximately 18 miles (30 km) when the vehicle is fully laden. In addition to the vehicle load, the driving distance possible depends upon: RSpeed RRoad condition temperature The driving distance possible in run-flat mode may be reduced by extreme driving conditions/maneuvers, or it can be increased through a moderate style of driving. The maximum permissible distance which can be driven in run-flat mode is counted from the moment the tire pressure loss warning appears in the multifunction display. You must not exceed a maximum speed of 50 mph (80 km/h). ROutside Roadside Assistance Flat tire 341 342 Flat tire When replacing one or all tires, make sure that you use only tires: Roadside Assistance Rof the size specified for the vehicle and Rmarked "MOExtended" If a tire has gone flat and cannot be replaced with a MOExtended tire, a standard tire may be used as a temporary measure. Make sure that you use the proper size and type (summer or winter tire). Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit may be obtained from a qualified specialist workshop.

Adjust the tire pressure as necessary (Y page 361). The service life of tires depends, among other things, on the following factors: RDriving style pressure RDistance covered RTire Important safety notes on the tire tread G WARNING Insufficient tire tread will reduce tire traction. The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk of hydroplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tire pressure is too high or too low, tires may exhibit different levels of wear at different locations on the tire tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires. Minimum tire tread depth for: RSummer tires: â in (3 mm) tires: ã in (4 mm) For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached. RM+S Bar indicator : for tread wear is integrated into the tire tread. Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once a tread depth of Z Wheels and tires When parking your vehicle, make sure that the tires do not get deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged. 359 360 Winter operation approximately á in (1.6 mm) has been reached. If this is the case, the tire is so worn that it must be replaced. Selecting, mounting and replacing tires Wheels and tires ROnly mount tires and wheels of the same type and make. Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the "MOExtended tires (tires with run-flat characteristics" section (Y page 341). ROnly mount tires of the correct size onto the wheels. RBreak in new tires at moderate speeds for the first 60 miles (100 km). They only reach their full performance after this distance. RDo not drive with tires which have too little tread depth, as this significantly reduces the traction on wet roads (hydroplaning). RReplace the tires after six years at the latest, regardless of wear. MOExtended tires (tires with run-flat properties) With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires. MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor and on wheels specifically tested by Mercedes-Benz. Notes on driving with MOExtended tires with a flat tire (Y page 341). i Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit can be obtained from a qualified specialist workshop. Winter operation General notes Have your vehicle winter-proofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 381). Driving with summer tires At temperatures below 45 ‡ (+7 †), summer tires lose elasticity and therefore traction and braking power. Change the tires on your vehicle to M+S tires. Using summer tires at very cold temperatures could cause cracks to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage. G WARNING Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tires regularly for signs of damage and replace any damaged tires immediately. M+S tires G WARNING M+S tires with a tire tread depth of less than ã in (4 mm) are not suitable for use in winter and do not provide sufficient traction. There is a risk of an accident. M+S tires with a tread depth of less than ã in (4 mm) must be replaced immediately. At temperatures below 45 ‡ (+7 †), use winter tires or all-season tires. Both types of tire are identified by the M+S marking. Only winter tires bearing the i snowflake symbol in addition to the M+S marking pro- Check Check the tire pressures (Y page 365). Vehicles for Canada: restart the tire pressure loss warning system (Y page 369). X Restart the tire pressure monitor (Y page 367). X X Snow chains G WARNING If snow chains are installed to the front wheels, they may drag against the vehicle body or chassis components. This could cause damage to the vehicle or the tires. There is a risk of an accident. To avoid hazardous situations: Rnever install snow chains to the front wheels Ralways install snow chains in pairs to the rear wheels. ! Vehicles with steel wheels: if you mount snow chains on steel wheels, you may damage the hub caps. Remove the hub caps from the relevant wheels before mounting the snow chains. For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding standard of quality. If you intend to mount snow chains, please bear the following points in mind: RSnow chains may not be mounted on all wheel/tire combinations. Permissible wheel-tire combinations (Y page 386). ROnly use snow chains when driving on roads completely covered by snow. Remove the snow chains as soon as possible when you come to a road that is not snow-covered. RLocal regulations may restrict the use of snow chains. Observe the appropriate regulations if you wish to mount snow chains. RDo not exceed the maximum permissible speed of 30 mph (50 km/h). ROn vehicles with AIRMATIC, you must drive at raised vehicle level if snow chains have been installed (Y page 197). You may wish to deactivate ESP® when pulling away with snow chains installed (Y page 72). You can thereby allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). Check Tire pressure specifications Important safety notes G WARNING Underinflated or overinflated tires pose the following risks: Rthe tires may burst, especially as the load and vehicle speed increase. Rthe tires may wear excessively and/or unevenly, which may greatly impair tire traction. Rthe driving characteristics, as well as steering and braking, may be greatly impaired. There is a risk of an accident. Z Wheels and tires vide the best possible grip in wintry road conditions. Only these tires will allow driving safety systems such as ABS and ESP® to function optimally in winter. These tires have been developed specifically for driving in snow. Use M+S tires of the same make and tread on all wheels to maintain safe handling characteristics. Always observe the maximum permissible speed specified for the M+S tires you have mounted. When you have mounted the M+S tires: 361 362 Check Follow recommended tire inflation pressures and check the pressure of all the tires including the spare wheel: Rmonthly, at least the load changes Rbefore beginning a long journey Runder different operating conditions, e.g. off-road driving If necessary, correct the tire pressure. Wheels and tires Rif The specifications on the sample Tire and Loading Information placard and tire pressure tables are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressure specifications that are valid for your vehicle can be found on the Tire and Loading Information placard and tire pressure table on the vehicle. General notes The recommended tire pressures for the tires mounted at the factory can be found on the labels described here. Further information on tire pressures can be obtained at a qualified specialist workshop. cold tires. The recommended tire pressures are valid for the maximum permissible load and up to the maximum permissible vehicle speed. Tire pressure table The tire pressure table is on the inside of the fuel filler flap. Example: tire pressure table for all tires permitted for this vehicle by the factory The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. Tire and Loading Information placard Example: tire pressure table with tire dimensions : Recommended tire pressures The Tire and Loading Information placard is on the B-pillar on the driver's side (Y page 369). The Tire and Loading Information placard contains the recommended tire pressures for If a tire size precedes a tire pressure, the tire pressure information following is only valid for that tire size. The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of occupants and amounts of luggage. The actual number of seats may differ. Check Rif you want to drive with an increased load and/or Rif you want to drive at higher road speeds The tire pressures for increased loads and/or higher road speeds, shown in the tire pressure table, may have a negative effect on driving comfort. If the tire pressure is not set correctly, this can lead to an excessive build up of heat and a sudden loss of pressure. For more information, contact a qualified specialist workshop. Important notes on tire pressure G WARNING If the tire pressure drops repeatedly, the wheel, valve or tire may be damaged. Tire pressure that is too low may result in a tire blow-out. There is a risk of an accident. RCheck the tire for foreign objects. RCheck whether the wheel is losing air or the valve is leaking. If you are unable to rectify the damage, contact a qualified specialist workshop. G WARNING If you fit unsuitable accessories onto tire valves, the tire valves may be overloaded and malfunction, which can cause tire pressure loss. Due to their design, retrofitted tire pressure monitors keep the tire valve open. This can also result in tire pressure loss. There is a risk of an accident. Only screw the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle onto the tire valve. Use a suitable pressure gauge to check the tire pressure. The outer appearance of a tire does not permit any reliable conclusion about the tire pressure. On vehicles equipped with the electronic tire pressure monitor, the tire pressure can be checked in the on-board computer. The tire temperature and pressure increase when the vehicle is in motion. This is dependent on the driving speed and the load. Therefore, you should only correct tire pressures when the tires are cold. The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has not been driven further than 1 mile (1.6 km) The tire temperature changes depending on the outside temperature, the vehicle speed and the tire load. If the tire temperature changes by 18 ‡ (10 †), the tire pressure changes by approximately 10 kPa (0.1 bar/ 1.5 psi). Take this into account when checking the pressure of warm tires. Only correct the tire pressure if it is too low for the current operating conditions. If you check the tire pressure when the tires are warm, the resulting value will be higher than if the tires were cold. This is normal. Do not reduce the tire pressure to the value specified for cold tires. The tire pressure would otherwise be too low. Z Wheels and tires Some tire pressure tables show only the rim diameters instead of the full tire size, e.g. R18. Rim diameter is part of the tire size and can be found on the tire sidewall (Y page 375). If the tire pressures have been set to the lower values for lighter loads and/or lower road speeds, the pressures should be reset to the higher values: 363 364 Check Observe the recommended tire pressures for cold tires: Ron the Tire and Loading Information placard on the B-pillar on the driver's side Rin the tire pressure table on the inside of the fuel filler flap Rhave Rbe an adverse effect on ride comfort more susceptible to damage Maximum tire pressures Underinflated or overinflated tires Wheels and tires Underinflated tires G WARNING Tires with pressure that is too low can overheat and burst as a consequence.

Information on air pressure for the tires on your vehicle can be found: Ron the vehicle's Tire and Loading Information placard on the B-pillar Ron the tire pressure label on the fuel filler flap Rin the "Tire pressure" section Check 365 Checking tire pressures manually To determine and set the correct tire pressure, proceed as follows: Remove the valve cap of the tire that is to be checked. X Press the tire pressure gauge securely onto the valve. X Read the tire pressure and compare it with the recommended value on the Tire and Loading Information placard (Y page 361). X If the tire pressure is too low, increase it to the recommended value. X If the tire pressure is too high, release air by pressing down the metal pin in the valve. Use the tip of a pen, for example. Then, check the tire pressure again using the tire pressure gauge. X Screw the valve cap onto the valve. X Repeat these steps for the other tires. X General notes If a tire pressure monitor is installed, the vehicle's wheels have sensors that monitor the tire pressures in all four tires. The tire pressure monitor warns you if the pressure drops in one or more of the tires. The tire pressure monitor only functions if the correct sensors are installed on all wheels. Information on tire pressures is displayed in the multifunction display. After a few minutes of driving, the current tire pressure of each tire is shown in the Service menu of the multifunction display; see illustration (example). Important safety notes G WARNING Each tire, including the spare (if provided), should be checked at least once every two weeks when cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire and Loading Information placard on the driver's door B-pillar or the tire pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or, if available, the tire pressure label, you should determine the proper tire pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure telltale lights up, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire pressure, even if Z Wheels and tires Tire pressure monitor For information on the message display, refer to the "Checking the tire pressure electronically" section (Y page 367). Wheels and tires 366 Check underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the warning lamp will flash for approximately a minute and then remain continuously illuminated. This sequence will be repeated every time the vehicle is started as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate Tires and wheels allow the TPMS to continue to function properly. It is the driver's responsibility to set the tire pressure to that recommended for cold tires which is suitable for the operating situation (Y page 361). Note that the correct tire pressure for the current operating situation must first be taught-in to the tire pressure monitor. If there is a substantial loss of pressure, the warning threshold for the warning message is aligned to the reference values taught-in. Restart the tire pressure monitor after adjusting the pressure of the cold tires (Y page 367). The current pressures are saved as new reference values. As a result, a warning message will appear if the tire pressure drops significantly. The tire pressure monitor does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 361). The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers. The tire pressure monitor has a yellow warning lamp in the instrument cluster for indicating a pressure loss or malfunction. Whether the warning lamp flashes or lights up indicates whether a tire pressure is too low or the tire pressure monitor is malfunctioning: Rif the warning lamp is lit continuously, the tire pressure on one or more tires is significantly too low. The tire pressure monitor is not malfunctioning. Rif the warning lamp flashes for around a minute and then remains lit constantly, the tire pressure monitor is malfunctioning. In addition to the warning lamp, a message appears in the multifunction display. Further information can be found on (Y page 277). If the tire pressure monitor is malfunctioning, it may take more than ten minutes for the tire pressure warning lamp to inform you of the malfunction by flashing for approximately one minute and then remaining lit. When the malfunction has been rectified, the tire pressure warning lamp goes out after a few minutes of driving. The tire pressure values indicated by the onboard computer may differ from those measured at a gas station with a pressure gauge. The tire pressures shown by the on-board computer refer to those measured at sea level. At high altitudes, the tire pressure values indicated by a pressure gauge are higher than those shown by the on-board computer. In this case, do not reduce the tire pressures. The operation of the tire pressure monitor can be affected by interference from radio transmitting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle. Check Make sure that the SmartKey is in position 2 in the ignition lock (Y page 157).

RIf the Please Correct Tire Pressure message appears in the multifunction display, the tire pressure in at least one tire is too low and must be corrected at the next opportunity. RIf the Check Tires message appears in the multifunction display, the tire pressure in one or more tires has dropped significantly and the tires must be checked. RIf the Caution Tire Malfunction appears in the multifunction display, the tire pressure in one or more tires has dropped suddenly and the tires must be checked. Observe the instructions and safety notes in the display messages in the "Tires" section (Y page 277). If the wheel positions on the vehicle are rotated, the tire pressures may be displayed for the wrong positions for a short time. This is rectified after a few minutes of driving, and the tire pressures are displayed for the correct positions. Restarting the tire pressure monitor When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring. In most cases, the tire pressure monitor will automatically detect the new reference values after you have changed the tire pressure. However, you can also define reference values manually as described here. The tire pressure monitor then monitors the new tire pressure values.

X Step 1: Locate the statement "The combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s Tire and Loading Information placard. X Step 2: Determine the combined weight of the driver and passengers that will be riding in your vehicle. X Step 3: Subtract the combined weight of the driver and passengers from XXX kilograms or XXX lbs. X Step 4: The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs and there will be five 150-lb passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 - 750 (5 x 150) = 650 lbs). X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4.

Permissible Gross Vehicle Weight Rating (GVWR): the gross weight of the vehicle, all passengers, load and trailer load/noseweight (if applicable) must not exceed the permissible gross vehicle weight. Gross Axle Weight Rating (GAWR): the maximum permissible weight that can be carried by one axle (front or rear axle). To ensure that your vehicle does not exceed the maximum permissible values (gross vehicle weight and maximum gross axle weight rating), have your loaded vehicle (including driver, occupants, cargo, and full trailer load if applicable) weighed on a suitable vehicle weighbridge. Uniform Tire Quality Grading Standards Overview of Tire Quality Grading Standards Uniform Tire Quality Grading Standards are U.S. government specifications. Their purpose is to provide drivers with uniform reliable information on tire performance data. Tire manufacturers have to grade tires using three performance factors: : tread wear grade, ; traction grade and = temperature grade. These regulations do not apply to Canada. Nevertheless, all tires sold in North America are provided with the corresponding quality grading markings on the sidewall of the tire. Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum tire width. Z Wheels and tires Example 1 374 All about wheels and tires Example: RTreadwear grade: 200 grade: AA RTemperature grade: A All passenger car tires must conform to the statutory safety requirements in addition to these grades. RTraction i The actual values for tires are vehicle- specific and may deviate from the values in the illustration. Wheels and tires Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified U.S. government course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate conditions. Traction G WARNING The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. ! Avoid wheelspin. This can lead to damage to the drive train. The traction grades – from highest to lowest – are AA, A, B and C. Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces. You should pay special attention to road conditions when temperatures are around freezing point. Mercedes-Benz recommends a minimum tread depth of ã in (4 mm) on all four winter tires. Observe the legally required minimum tire tread depth (Y page 359). Winter tires can reduce the braking distance on snow-covered surfaces in comparison with summer tires. The braking distance is still much further than on surfaces that are not icy or covered with snow. Take appropriate care when driving. Further information on winter tires (M+S tires) (Y page 360). Temperature G WARNING The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possible tire failure. The temperature grades are A (the highest), B, and C. They represent the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. All about wheels and tires Overview : Uniform Tire Quality Grading Standard (Y page 379) ; DOT, Tire Identification Number (Y page 378) Maximum tire load (Y page 377) Maximum tire pressure (Y page 364) Manufacturer Tire material (Y page 378) Tire size designation, load-bearing capacity and speed rating (Y page 375) D Load index (Y page 377) E Tire name = ?

Tire size designation, load-bearing capacity and speed rating G WARNING Exceeding the stated tire load-bearing capacity and the approved maximum speed could lead to tire damage or the tire bursting. There is a risk of accident. Therefore, only use tire types and sizes approved for your vehicle model. Observe the tire load rating and speed rating required for your vehicle. : ; = ? A B Tire width Nominal aspect ratio in % Tire code Rim diameter Load bearing index Speed rating General: depending on the manufacturer's standards, the size imprinted in the tire wall may not contain any letters or may contain one letter that precedes the size description. If there is no letter preceding the size description (as shown above): these are passenger vehicle tires according to European manufacturing standards. If "P" precedes the size description: these are passenger vehicle tires according to U.S. manufacturing standards. If "LT" precedes the size description: these are light truck tires according to U.S. manufacturing standards. If "T" precedes the size description: these are compact emergency spare wheels at high tire pressure, to be used only temporarily in an emergency. Tire width: tire width : shows the nominal tire width in millimeters. Height-width ratio: aspect ratio ; is the size ratio between the tire height and tire width and is shown in percent. The aspect Z Wheels and tires Tire labeling 375 Wheels and tires 376 All about wheels and tires ratio is calculated by dividing the tire width by the tire height. Tire code: tire code = specifies the tire type. "R" represents radial tires; "D" represents diagonal tires; "B" represents diagonal radial tires. Optionally, tires with a maximum speed of over 149 mph (240 km/h) may have "ZR" in the size description, depending on the manufacturer (e.g. 245/40 ZR 18). Rim diameter: rim diameter ? is the diameter of the bead seat, not the diameter of the rim flange. The rim diameter is specified in inches (in). Load-bearing index: load-bearing index A is a numerical code that specifies the maximum load-bearing capacity of a tire. Do not overload the tires by exceeding the specified load limit. The maximum permissible load can be found on the vehicle's Tire and Loading Information placard on the B-pillar on the driver's side (Y page 369). Example: Load-bearing index 91 indicates a maximum load of 1,356 lb (615 kg) that the tires can bear. For further information on the maximum tire load in kilograms and lbs, see (Y page 377). For further information on the load bearing index, see "Load index" (Y page 377). Speed rating: speed rating B specifies the approved maximum speed of the tire. i Tire data is vehicle-specific and may deviate from the data in the example. Regardless of the speed rating, always observe the speed limits. Drive carefully and adapt your driving style to the traffic conditions. Summer tires Index Speed rating Q up to 100 mph (160 km/h) R up to 106 mph (170 km/h) Index Speed rating S up to 112 mph (180 km/h) T up to 118 mph (190 km/h) H up to 130 mph (210 km/h) V up to 149 mph (240 km/h) W up to 168 mph (270 km/h) Y up to 186 mph (300 km/h) ZR...Y up to 186 mph (300 km/h) ZR...(..Y) over 186 mph (300 km/h) ZR over 149 mph (240 km/h) ROptionally, tires with a maximum speed of over 149 mph (240 km/h) may have "ZR" in the size description, depending on the manufacturer (e.g. 245/40 ZR18). The service specification is made up of load-bearing index A and speed rating B. RIf the size description of your tire includes "ZR" and there are no service specifications, ask the tire manufacturer in order to find out the maximum speed. If a service specification is available, the maximum speed is limited according to the speed rating in the service specification. Example: 245/40 ZR18 97 Y. In this example, "97 Y" is the service specification. The letter "Y" represents the speed rating. The maximum speed of the tire is limited to 186 mph (300 km/h). RThe size description for all tires with maximum speeds of over 186 mph (300 km/h) must include "ZR", and the service specification must be given in parentheses. Example: 275/40 ZR 18 (99 Y). Speed rating "(Y)" indicates that the maximum speed of the tire is over 186 mph (300 km/h). Ask the tire manufacturer about the maximum speed. All about wheels and tires All-weather tires and winter tires Index Speed rating Q M+S1 up to 100 mph (160 km/h) T M+S1 up to 118 mph (190 km/h) H M+S1 up to 130 mph (210 km/h) V M+S1 up to 149 mph (240 km/h) 377 Load index the driving characteristics of winter tires. In addition to the M+S marking, winter tires also have the i snowflake symbol on the tire wall. Tires with this marking fulfill the requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) regarding the tire traction on snow. They have been especially developed for driving on snow. An electronic speed limiter prevents your vehicle from exceeding a speed of 130mph (210km/h). The speed rating of tires mounted at the factory may be higher than the maximum speed that the electronic speed limiter permits. Make sure that your tires have the required speed rating, e.g. when buying new tires. The required speed rating for your vehicle can be found in the "Tires" section (Y page 386). Further information about reading tire data can be obtained from any qualified specialist workshop. In addition to the load-bearing index, load index : may also be imprinted on the sidewall of the tire. You will find this after the letter that identifies the speed rating (Y page 375).

DOT, Tire Identification Number (TIN) US tire regulations stipulate that every tire manufacturer or retreader must imprint a TIN in or on the sidewall of each tire produced. Tire type code: tire type code ? can be used by the manufacturer as a code to describe specific characteristics of the tire. Date of manufacture: date of manufacture A provides information about the age of a tire. The first and second positions represent the week of manufacture, starting with "01" for the first calendar week. Positions three and four represent the year of manufacture. For example, a tire that is marked with "3208", was manufactured in week 32 in 2008. i Tire data is vehicle-specific and may deviate from the data in the example. Wheels and tires Tire characteristics The TIN is a unique identification number. The TIN enables the tire manufacturers or retreaders to inform purchasers of recalls and other safety-relevant matters. It makes it possible for the purchaser to easily identify the affected tires. The TIN is made up of manufacturer identification code ;, tire size =, tire type code ? and manufacturing date A. DOT (Department of Transportation): tire symbol : marks that the tire complies with the requirements of the U.S. Department of Transportation. Manufacturer identification code: manufacturer identification code ; provides details on the tire manufacturer. New tires have a code with two symbols. Retreaded tires have a code with four symbols. For further information about retreaded tires, see (Y page 358). Tire size: identifier = describes the tire size. This information describes the type of tire cord and the number of layers in sidewall : and under tire tread ;. i Tire data is vehicle-specific and may deviate from the data in the example. Definition of terms for tires and loading Tire ply composition and material used Describes the number of plies or the number of layers of rubber-coated fabric in the tire tread and sidewall. These are made of steel, nylon, polyester and other materials. Bar Metric unit for tire pressure. 14.5038 pounds per square inch (psi) and 100 kilopascals (kPa) are the equivalent of 1 bar. All about wheels and tires Normal occupant weight The number of occupants for which the vehicle is designed multiplied by 68 kilograms (150 lbs). Uniform Tire Quality Grading Standards A uniform standard to grade the quality of tires with regards to tread quality, tire traction and temperature characteristics. The quality grading assessment is made by the manufacturer following specifications from the U.S. government. The ratings are molded into the sidewall of the tire. Recommended tire pressures The recommended tire pressure applies to the tires mounted at the factory. The Tire and Loading Information placard contains the recommended tire pressures for cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed. The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. Increased vehicle weight due to optional equipment The combined weight of all standard and optional equipment available for the vehicle, regardless of whether it is actually installed on the vehicle or not. Rim This is the part of the wheel on which the tire is mounted. GAWR (Gross Axle Weight Rating) The GAWR is the maximum gross axle weight rating. The actual load on an axle must never exceed the gross axle weight rating. The gross axle weight rating can be found on the vehicle identification plate on the B-pillar on the driver's side. Speed rating The speed rating is part of the tire identification. It specifies the speed range for which the tire is approved. GVW (Gross Vehicle Weight) The gross vehicle weight includes the weight of the vehicle including fuel, tools, the spare wheel, accessories installed, occupants, luggage and the drawbar noseweight, if applicable. The gross vehicle weight must not exceed the gross vehicle weight rating GVWR as specified on the vehicle identification plate on the B-pillar on the driver's side. GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross weight of a fully loaded vehicle (the weight of the vehicle including all accessories, occupants, fuel, luggage and the drawbar noseweight, if applicable). The gross vehicle weight rating is specified on the vehicle identification plate on the B-pillar on the driver's side. Maximum loaded vehicle weight The maximum weight is the sum of: Rthe curb weight of the vehicle weight of the accessories Rthe load limit Rthe weight of the factory installed optional equipment Rthe Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa corresponds to 1 psi. Another unit for tire pressure is bar. 100 kilopascals (kPa) are the equivalent of 1 bar. Load index In addition to the load-bearing index, the load index may also be imprinted on the sidewall of the tire. This specifies the load-bearing capacity more precisely. Z Wheels and tires DOT (Department of Transportation) DOT-marked tires fulfill the requirements of the U S Department of Transportation. 379 380 All about wheels and tires Curb weight The weight of a vehicle with standard equipment including the maximum capacity of fuel, oil and coolant. It also includes the air-conditioning system and optional equipment if these are installed in the vehicle, but does not include passengers or luggage. Maximum load rating The maximum load rating is the maximum permissible weight in kilograms or lbs for which a tire is approved. Wheels and tires Maximum permissible tire pressure Maximum permissible tire pressure for one tire. Maximum load on one tire Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle by two. PSI (pounds per square inch) A standard unit of measure for tire pressure. Aspect ratio Relationship between tire height and tire width in percent. Tire pressure This is pressure inside the tire applying an outward force to each square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. Cold tire pressure The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has not been driven further than 1 mile (1.6 km) Tread The part of the tire that comes into contact with the road. Bead The tire bead ensures that the tire sits securely on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from the wheel rim. Sidewall The part of the tire between the tread and the bead. Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard parts and more than 5 lbs (2.3 kg). These optional extras, such as high-performance brakes, level control, a roof rack or a highperformance battery, are not included in the curb weight and the weight of the accessories. TIN (Tire Identification Number) This is a unique identifier which can be used by a tire manufacturer to identify tires, for example for a product recall, and thus identify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire type code and the manufacturing date. Load bearing index The load bearing index (also load index) is a code that contains the maximum load bearing capacity of a tire. Traction Traction is the result of friction between the tires and the road surface. Treadwear indicators Narrow bars (tread wear bars) that are distributed over the tire tread. If the tire tread is level with the bars, the wear limit of á in (1.6 mm) has been reached. Changing a wheel Total load limit Nominal load and luggage load plus 68 kg (150 lbs) multiplied by the number of seats in the vehicle. Changing a wheel Flat tire The "Breakdown assistance" section (Y page 341) contains information and notes on how to deal with a flat tire. Information on driving with MOExtended tires in the event of a flat tire can be found under "MOExtended tires (tires with run-flat characteristics" (Y page 341). Rotate the wheels before a clear wear pattern has formed on the tires. Front tires typically wear more on the shoulders and the rear tires in the center. If your vehicle's tire configuration allows, you can rotate the wheels according to the intervals in the tire manufacturer's warranty book in your vehicle documents. If no warranty book is available, the tires should be rotated every 3,000 to 6,000 miles (5,000 to 10,000 km), or earlier if tire wear requires. Ensure the direction of rotation is maintained. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rotated. Check the tire pressure and, if necessary, restart the tire pressure loss warning system (Y page 369) or the tire pressure monitor (Y page 367). Direction of rotation Rotating the wheels G WARNING Interchanging the front and rear wheels may severely impair the driving characteristics if the wheels or tires have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of accident. Rotate front and rear wheels only if the wheels and tires are of the same dimensions. ! On vehicles equipped with a tire pressure monitor, electronic components are located in the wheel. Tire-mounting tools should not be used near the valve. This could damage the electronic components. Only have tires changed at a qualified specialist workshop. Always observe the instructions and safety notes in the "Mounting a wheel" section (Y page 381). The wear patterns on the front and rear tires differ, depending on the operating conditions. Tires with a specified direction of rotation have additional benefits, e.g. if there is a risk of hydroplaning. You will only gain these benefits if the correct direction of rotation is maintained. An arrow on the sidewall of the tire indicates its correct direction of rotation. Storing wheels Store wheels that are not being used in a cool, dry and preferably dark place. Protect the tires from oil, grease, gasoline and diesel. Mounting a wheel Preparing the vehicle Stop the vehicle on solid, non-slippery and level ground. X Apply the electric parking brake manually.

Notes on the vehicle equipment – always equip the vehicle with: Rtires of the same size on a given axle (left/ right) Rthe same type of tires at a given time (summer tires, winter tires, MOExtended tires) Exception: it is permissible to install a different type or make in the event of a flat tire. Observe the "MOExtended tires (tires with run-flat characteristics" section (Y page 341). Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit may be obtained from a qualified specialist workshop. i Not all wheel and tire combinations are available at the factory for all countries. i On the following pages, you can find infor- mation on approved wheel rims and tire sizes for equipping your vehicle with winter tires. Winter tires are not available at the factory as standard equipment or optional extras. If you would like to equip your vehicle with approved winter tires, you may also, in certain circumstances, require rims of the appropriate size. The size of the approved winter tires may deviate from that of the standard tires. This is dependent on the model and the equipment installed at the factory.

Model Engine oil General notes ! Never use engine oil or an oil filter of a Technical data specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. You could otherwise cause engine damage or damage to the exhaust gas aftertreatment. Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment. When handling engine oil, observe the important safety notes on service products (Y page 397). The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center. Or visit the website http://bevo.mercedes-benz.com. The table shows which engine oils have been approved for your vehicle. Model Engin e model MB Approval C 300 C 300 4MATIC 274 229.3, 229.5, 229.51, 229.52 C 400 4MATIC 276 229.5 AMG vehicles 177 229.5 i MB approval is indicated on the oil containers. Capacity C 300 C 300 4MATIC 7.4 qt (7.0 l) C 400 4MATIC 6.9 qt (6.5 l) Additives ! Do not use any additives in the engine oil. This could damage the engine. Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Select an engine oil with an SAE classification (viscosity) suitable for the prevailing outside temperatures. The table shows you which SAE classifications are to be used. The lowtemperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification. Service products and filling capacities G WARNING The brake fluid constantly absorbs moisture from the air. This lowers the boiling point of the brake fluid. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied hard. This would impair braking efficiency. There is a risk of an accident. You should have the brake fluid renewed at the specified intervals. When handling brake fluid, observe the important safety notes on service products (Y page 397). The brake fluid change intervals can be found in the Maintenance Booklet. Only use brake fluid approved by MercedesBenz according to MB Approval 331.0.
