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 personal driving style You can influence both factors. You should bear the following in mind: Operating conditions: Ryour Ravoid short trips as these increase fuel consumption. Ralways 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: 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. Rswitch off the engine in stationary traffic. an eye on the vehicle's fuel consumption. Rkeep 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. Genuine Mercedes-Benz parts H Environmental note Daimler AG also supplies reconditioned major assemblies and parts which are of the same quality as new parts.

European Delivery Department 98 Vanderhoof Avenue Toronto, Ontario M4G 4C9 Operating safety Important safety notes G WARNING If you do not have the prescribed service/ maintenance work or any required repairs carried out, this can result in malfunctions or system failures. There is a risk of an accident. Always have the prescribed service/ maintenance work as well as any required repairs carried out at a qualified specialist workshop. 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 Modifications to electronic components, their software as well as wiring can impair their function and/or the function of other networked components. In particular, systems relevant to safety could also be affected. As a result, these may no longer function as intended and/or jeopardize the operating safety of the vehicle. There is an increased risk of an accident and injury. Never tamper with the wiring as well as electronic components or their software. You should have all work to electrical and electronic equipment carried out at a qualified specialist workshop. ! There is a risk of damage to the vehicle if: Rthe vehicle becomes stuck, e.g. on a high curb or an unpaved road drive too fast over an obstacle, e.g. a curb or a hole in the road Ra heavy object strikes the undercarriage or parts of the chassis. Ryou Introduction In situations like this, the body, the undercarriage, chassis parts, wheels or tires could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, no longer withstand the strain they are designed to. If the underbody paneling is damaged, combustible materials such as leaves, grass or twigs can gather between the underbody and the underbody paneling. If these materials come in contact with hot parts of the exhaust system for an extended period, they can catch fire. Have the vehicle checked and repaired immediately at a qualified specialist workshop. If on continuing your journey you notice that driving safety is impaired, pull over and stop the vehicle immediately, paying attention to road and traffic conditions. In such cases, visit a qualified specialist workshop.

This also applies to safetyrelated systems and functions. i Read the information on qualified specialist workshops: (Y page 25). Occupant safety Overview of occupant safety In this section, you will learn the most important facts about the restraint system components of the vehicle. The restraint system consists of: Rseat belts restraint systems RLATCH-type (ISOFIX) child seat anchors Additional protection is provided by: Rchild RSRS (Supplemental Restraint System) head restraints/NECK-PRO luxury head restraints Rair bag system components with: - PASSENGER AIR BAG OFF indicator lamp - front-passenger seat with Occupant Classification System (OCS) The different air bag systems work independently of each other. The protective functions of the system work in conjunction with each other. Not all air bags are always deployed in an accident. RNECK-PRO Panic alarm G WARNING To activate: press ! button : for approximately 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 X Press the KEYLESS-GO Start/Stop button. The KEYLESS-GO key must be in the vehicle. X Modifications to or work improperly conducted on restraint system components or their wiring, as well as tampering with interconnected electronic systems, can lead to the restraint systems no longer functioning as intended. Air bags or Emergency Tensioning Devices (ETDs), for example, could deploy inadvertently or fail to deploy in accidents although the deceleration threshold for air bag deployment is exceeded. Therefore, never modify the restraint systems. Do not tamper with electronic components or their software. i For information on infants and children traveling with you in the vehicle restraint systems for infants and children, see "Children in the vehicle" (Y page 59). Occupant safety Introduction SRS consists of: RThe 6 SRS warning lamp bags RAir bag control unit (with crash sensors) REmergency Tensioning Devices RBelt force limiters SRS reduces the risk of occupants coming into contact with the vehicle's interior in the event of an accident. It can also reduce the effect of the forces to which occupants are subjected during an accident. RAir SRS warning lamp G WARNING If SRS is malfunctioning, child 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. There is an increased risk of injury, possibly even fatal. Have SRS checked and repaired immediately at a qualified specialist workshop. SRS functions are checked regularly when you switch on the ignition and when the engine is running. Therefore, malfunctions can be detected in good time. The 6 SRS 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 SRS components are in operational readiness when the 6 SRS warning lamp goes out while the engine is running. There is a malfunction if: Rthe 6 SRS warning lamp does not light up when the ignition is switched on Rthe engine is running and the 6 SRS warning lamp does not go out after a few seconds Rthe engine is running and the 6 SRS warning lamp lights up again Safety guidelines for seat belts, Emergency Tensioning Devices (ETDs) and air bags G WARNING RDamaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Their anchoring points must also be checked. Only use seat belts installed or supplied by an authorized Mercedes-Benz Center. RAir bags and pyrotechnic Emergency Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and regard for the environment. Check your national disposal guidelines. California residents, see www.dtsc.ca.gov/HazardousWaste/ Perchlorate/index.cfm. RAir bags and ETDs are designed to function on a one-time-only basis. An air bag or ETD that has deployed must be replaced. RDo not pass seat belts over sharp edges. They could tear. RDo not make any modification that could change the effectiveness of the seat belts. RDo not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. RNo modifications of any kind may be made to any components or wiring of the SRS. RDo not change or remove any component or part of the SRS. RDo not install additional trim material, seat covers, badges, etc. over the steering wheel hub, front-passenger front air bag Z Safety SRS (Supplemental Restraint System) 41 Safety 42 Occupant safety cover, outer sides of the seat backrests, door trim panels, or door frame trims. RDo not install additional electrical/ electronic equipment on or near SRS components and wiring. RKeep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.). RDo not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed. RAir bag system components will be hot after an air bag has inflated. Do not touch them. RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat. RImproper repair work on the SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. RFor your protection and the protection of others, when scrapping the air bag unit or ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz Center. RGiven the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment. If you sell your vehicle, Mercedes-Benz strongly recommends that you inform the subsequent owner that the vehicle is equipped with SRS. Also, refer them to the applicable section in the Operator's Manual. Air bags Important safety notes G WARNING Using unsuitable seat covers could restrict or even prevent 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 air bag deactivation system could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz. G WARNING The air bag parts are hot after the airbag has been deployed. There is a risk of injury. Do not touch the air bag parts. Have the deployed air bags replaced at a qualified specialist workshop as soon as possible. G WARNING Air bags are designed to reduce the incidence of injuries and fatalities in certain situations: Rfrontal impacts (driver's and frontpassenger front air bags and driver's knee bag) Rside impacts (side impact air bags, window curtain air bags and pelvis air bags) However, no system available today can completely eliminate injuries and fatalities. When the air bags are deployed, a small amount of powder is released. The powder generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. In order to prevent potential breathing difficulties, you should leave the vehicle as soon as it is safe to do so. If you have any breathing difficulty but cannot get out of the vehicle after the air bag inflates, then get fresh air by opening a window or door. G WARNING In order to reduce the potential danger of injuries caused during the deployment of the front air bags, the driver and front passenger must always be correctly seated and wear their seat belts. For maximum protection in the event of a collision, you must always be in the normal seat position with your back against the backrest. Fasten your seat belt and make sure that it is correctly positioned on your body. As the air bag inflates with considerable speed and force, a proper seating position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag, as it inflates with great force instantaneously: Rsit with the seat belt fastened correctly and in a position that is as upright as possible with your back against the backrest. Rmove the driver's seat as far back as possible, still permitting proper operation of vehicle controls. The distance from the center of the driver's chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm). You should be able to accomplish this by adjusting the seat and steering wheel. If you have any difficulties, please contact an authorized Mercedes-Benz Center. Rdo not lean your head or chest close to the steering wheel or dashboard. Ronly hold the steering wheel on the outside. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury if the driver front air bag inflates. Radjust the front-passenger seat as far back as possible from the dashboard when the seat is occupied. Roccupants, especially children, should never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious or fatal injuries should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint or booster seat recommended for the size and weight of the child. Failure to follow these instructions can result in severe injuries to you or other occupants. If you sell your vehicle, it is important that you make the buyer aware of this safety information. Be sure to give the buyer this Operator's Manual. The air bag installation locations are identified by the AIR BAG symbol. The air bags are deployed if the air bag control unit detects the need for deployment. Only in the event of such a situation will the air bags provide their supplemental protection. If the driver and front passenger do not wear their seat belts, it is not possible for the air bags to provide their supplemental protection. In the event of other types of impacts and impacts below air bag deployment thresholds, the air bags will not deploy. The driver and passenger will then be protected to the extent possible by a properly fastened seat belt. A properly fastened seat belt is also needed to provide the best possible protection in a rollover. Air bags provide additional protection; they are not, however, a substitute for seat belts. All vehicle occupants must fasten their seat belts regardless of whether your vehicle is equipped with air bags or not. 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. Z 43 Safety Occupant safety 44 Occupant safety i After an air bag has been deployed, have Safety the vehicle towed to the nearest qualified specialist workshop, even if your vehicle is ready to drive. Front air bags The front air bags increase protection for the driver's and front passenger's head and chest. The deployment of front-passenger front air bag ; is also influenced by the weight category of the front passenger, which is determined by the Occupant Classification System (OCS) (Y page 47). The lighter the passenger-side occupant, the higher the vehicle deceleration rate required (predicted at the start of the impact) for second stage inflation of the front-passenger front air bag. In the second stage, the front air bags are inflated with the maximum amount of propellant gas available. The front air bags are not deployed in situations where a low impact severity is predicted. You will then be protected by the fastened seat belt. The front-passenger front air bag will only be deployed if: Rthe Driver's air bag : deploys in front of the steering wheel; front-passenger front air bag ; deploys in front of and above the glove box. They are deployed: Rat the start of an accident with a high rate of vehicle acceleration or deceleration in a longitudinal direction Rif the system determines that air bag deployment can offer additional protection to that provided by the seat belt Rindependently of other air bags in the vehicle The release time of the front air bags is dependent upon the use of the seat belt. Your vehicle has adaptive, two-stage front air bags. In the event of a collision, the air bag control unit evaluates the vehicle deceleration. In the first deployment stage, the front air bag is filled with enough propellant gas to reduce the risk of injuries. The front air bag is fully deployed if a second deployment threshold is exceeded within a few milliseconds. system, based on the OCS weight sensor readings, detects that the frontpassenger seat is occupied Rthe PASSENGER AIR BAG OFF indicator lamp on the center console is not lit (Y page 47) Rthe air bag control unit predicts a highimpact severity Driver's knee bag Driver's knee bag : increases the driver's protection against: Rknee injuries injuries Rlower leg injuries Rthigh Driver's knee bag : deploys under the steering column. If, during a frontal collision, the system determines that air bag deployment can offer additional protection to that provided by the seat belt, driver's knee bag : is deployed along with the driver's air bag. Driver's knee bag : operates best in conjunction with correctly positioned and fastened seat belts. Side impact air bags intended protection in the event of an accident. When deployed, the side impact air bags offer additional protection for the thorax of the vehicle occupants on the side of the vehicle on which the impact occurs. However, they do not protect the: Rhead Rneck Rarms G WARNING Using unsuitable seat covers could restrict or even prevent 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 air bag deactivation system could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz. 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. You should only use seat covers that have been approved for your vehicle by MercedesBenz. The seat covers must have a special tear seam for side impact air bags. Otherwise, the side impact air bags cannot deploy correctly and therefore cannot provide the Front side impact air bags : and rear side impact air bags ; deploy next to the outer seat cushions.

Rthe Z 45 Safety Occupant safety 46 Occupant safety Safety The side impact air bag on the frontpassenger side will deploy if the frontpassenger seat belt is fastened, regardless of whether the front-passenger seat is occupied or not. Pelvis air bags Pelvis air bags are not available for AMG vehicles. G WARNING Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using seat covers or other seat coverings can cause a malfunction of the side impact air bags and/or the pelvis air bags. Contact an authorized Mercedes-Benz Center for availability. Pelvis air bag deployment enhances the level of protection of the vehicle occupants on the side of the vehicle on which the impact occurs. Pelvis air bags : deploy next to and below the outer seat cushions. They are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact Rindependently of the use of the seat belt Rindependently of the front air bags Rindependently of the ETDs Pelvis air bags : will not deploy in side impacts which do not exceed the system's preset deployment thresholds for lateral acceleration/deceleration.

Occupant Classification System (OCS) How the Occupant Classification System works The Occupant Classification System (OCS) categorizes the occupant on the frontpassenger seat using a weight sensor. The front-passenger front air bag is deactivated automatically for certain weight categories. The PASSENGER AIR BAG OFF indicator lamp shows you the current status. If the PASSENGER AIR BAG OFF indicator lamp is lit, the passenger air bag is disabled. The system does not deactivate: Rthe side impact air bag pelvis air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices To be classified correctly, the front passenger must sit: Rthe Rwith the seat belt fastened correctly a position that is as upright as possible with their back against the seat backrest Rwith their feet on the floor The OCS weight sensor reading is affected if the occupant's weight is transferred, e.g. by leaning on the armrest. If the front-passenger seat, the seat cover or the seat cushion are damaged, have the necessary repair work carried out at a qualified specialist workshop. For safety reasons, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. Both the driver and the front passenger should always observe the PASSENGER AIR BAG OFF indicator lamp as an indication of whether or not the front passenger is positioned correctly. Observe also the air bag Rin If the 45 indicator lamp illuminates when an adult or someone larger than a small individual is in the front passenger seat, have the front passenger reposition himself or herself in the seat until the 45 indicator lamp goes out. In the event of a collision, the air bag control unit will not allow front passenger front air bag deployment when the OCS has classified the front passenger seat occupant as weighing as much as or less than a typical 12-month-old child in a standard child restraint or if the front passenger seat is classified as being empty. When the OCS senses that the front passenger seat occupant is classified as being up to or less than the weight of a typical 12-month-old child in a standard child restraint, the 45 indicator lamp will illuminate when the engine is started and remain illuminated. This indicates that the front passenger front air bag is deactivated. When the OCS senses that the front passenger seat is classified as being empty, the 45 indicator lamp will illuminate when the engine is started and remain illuminated. This indicates that the front passenger front air bag is deactivated. When the OCS senses that the front passenger seat occupant is classified as being heavier than the weight of a typical 12month-old child seated in a standard child restraint or as being a small individual (such as a young teenager or a small adult), the 45 indicator lamp will illuminate for approximately 6 seconds when the engine is started. Depending on occupant weight sensor readings from the seat, it will then remain illuminated or go out. With the 45 indicator lamp illuminated, the front passenger front air bag is deactivated. With the 45 indicator lamp out, the front passenger front air bag is activated. Z Safety G WARNING Safety 48 Occupant safety When the OCS senses that the front passenger seat occupant is classified as an adult or someone larger than a small individual, the 45 indicator lamp will illuminate for approximately six seconds when the engine is started and then go out. This indicates that the front passenger front air bag is activated. If the 45 indicator lamp is illuminated, the front passenger front air bag is deactivated and will not be deployed. If the 45 indicator lamp is not illuminated, the front passenger front air bag is activated and will be deployed Rin the event of certain frontal impacts the impact exceeds a predetermined triggering threshold Rindependent of the side impact air bag or pelvis air bag If the front passenger front air bag is deployed, the rate of inflation will be influenced by Rif Rthe rate of vehicle deceleration as assessed by the air bag control unit front passenger's weight category as identified by the OCS Rthe G WARNING According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle's seat belt, the seat belt and Top Tether strap, or lower anchors and Top Tether strap, fully in accordance with the child seat manufacturer's instructions. Occupants, especially children, should always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the frontpassenger seat: RYour vehicle is equipped with air bag technology designed to deactivate the front-passenger front air bag in your vehicle when the system senses the weight of a typical 12-month-old child or less along with the weight of a standard appropriate child restraint on the front-passenger seat. RA child in a rear-facing child restraint on the front-passenger seat will be seriously injured or even killed if the front-passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to eliminate this risk completely is never to place a child in a rear-facing child restraint in the frontpassenger seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint on the rear seat. RIf you install a rear-facing child restraint on the front-passenger seat, make sure the 45 indicator lamp is illuminated, indicating that the front-passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure that the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, do not transport a child on the front-passenger seat until the system has been repaired. Occupant safety If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The OCS may have detected that the seat: Ris empty or occupied by the weight of a typical child up to twelve months old, seated in a child restraint system. Ris occupied by a small individual, such as a young teenager or a small adult.

Correct use of the seat belts G WARNING USE SEAT BELTS PROPERLY RSeat belts can only work when used properly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in the event of an accident. REach occupant should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, including rollovers. The integrated restraint system includes SRS (driver front air bag, driver's side knee bag, front-passenger front air bag, side impact air bags, pelvis air bags, window curtain air bags for the side windows), Emergency Tensioning Devices, seat belt force limiters, and front seat knee bolsters. The system is designed to enhance the protection offered to properly belted occupants in certain frontal (front air bags, driver's side knee bag, and ETDs) and side (side impact air bags, pelvis air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds. RNever wear the shoulder belt under your arm, across your neck or off your shoulder. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. The seat belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen. Adjust the seat belt so that the shoulder section is located as close as possible to the middle of the shoulder. It should not touch the neck. Never pass the shoulder portion of the seat belt under your arm. RPosition the lap belt as low as possible on your hips and not across the abdomen. If the lap belt is positioned across your abdomen, it could cause serious injuries in a crash. RNever wear seat belts over rigid or breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries. RMake sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing. RNever use a seat belt for more than one person at a time. Do not fasten a seat belt around a person and another person or other objects at the same time. RSeat belts should not be worn twisted. In a crash, you would not have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries. RPregnant women should also always use a lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen. RPlace the seat backrest in a position that is as upright as possible. RCheck your seat belt during travel to make sure it is properly positioned. RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.

The Emergency Tensioning Devices are triggered depending on the type and severity of an accident, if: Rin the event of a head-on or rear-end collision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact Rin the event of a side impact, the vehicle decelerates or accelerates rapidly in a lateral direction on the side opposite the impact If the ETDs are deployed, you will hear a bang, and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. The dust might cause some temporary breathing difficulty for people with asthma or other breathing trouble. To avoid this, you may wish to get out of the vehicle as soon as it is safe to do so. You can also open the window to allow fresh air to enter the vehicle interior. The 6 SRS warning lamp lights up. If the seat belt is also equipped with a seat belt force limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced. The seat belt force limiters for the front seats are synchronized with the front air bags, which take on a part of the deceleration force. This results in the force exerted on the occupant being distributed over a greater area. Always read and follow the manufacturer's instructions when using an infant or child restraint system or booster seat. Observe all warning signs in the vehicle interior and on the infant or child restraint. G WARNING 50 states U.S. territories Rthe District of Columbia Rall Canadian provinces Infants and children must always be seated in an appropriate infant or child restraint system recommended for the size and weight of the child.

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. i 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 314). 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 yellow ! 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 65). 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 250) and display messages which may be shown in the instrument cluster (Y page 223). ABS works from a speed of about 5 mph (8 km/h), regardless of road-surface conditions. ABS works on slippery surfaces, even if you only brake gently. 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 Z Safety operation is possible using the switches in the rear compartment. 65 Driving safety systems Safety 66 BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. For BAS PLUS to assist you, the radar sensor system must be operational. With the help of the radar sensor system, BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time. If the radar sensor system is malfunctioning, BAS PLUS will not be available. The brake system is still available with complete brake boosting effect and BAS. BAS PLUS can help you to minimize the risk of a collision with a vehicle or reduce the effects of such a collision. If BAS PLUS detects a danger of collision, you are assisted when braking. Important safety notes Important safety notes 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 i Observe the "Important safety notes" section (Y page 65). 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) General information i Observe the "Important safety notes" section (Y page 65). BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS. G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. 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. Rnot G WARNING BAS PLUS does not react: Rto people or animals oncoming vehicles Rto crossing traffic 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. Driving safety systems Recognition by the radar sensor system is also impaired in the event of: on the sensors or anything else covering the sensors Rinterference 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 relative to the center of your vehicle 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. 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). At speeds of up to approximately 40 mph (70 km/h), BAS PLUS can also react to stationary objects. Examples of stationary objects are stopped or parked vehicles. RBAS 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 Rthere ESP® (Electronic Stability Program) General notes i Observe the "Important safety notes" section (Y page 65). 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. ETS/4ETS (Electronic Traction System) i Observe the "Important safety notes" section (Y page 65). ETS/4ETS traction control 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®. Z Safety Rdirt 67 68 Driving safety systems Important safety notes Characteristics of ESP i Observe the "Important safety notes" General information If the ÷ ESP warning lamp goes out before beginning the journey, ESP® is automatically active.

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. ! When testing the electric parking brake on a braking dynamometer, switch off the ignition. Application of the brakes by ESP® may otherwise destroy the brake system. Vehicles without 4MATIC: observe the notes on ESP®(Y page 309) when towing the vehicle with a raised rear axle. ! Vehicles with 4MATIC: function or performance tests may only be carried out on a 2-axle dynamometer. Before you operate the vehicle on such a dynamometer, please consult a qualified workshop. You could otherwise damage the drive train or the brake system. ESP® is deactivated if the å warning lamp in the instrument cluster lights up continuously when the engine is running. If the ÷ warning lamp and the å warning lamp are lit continuously, ESP® is not available due to a malfunction. Observe the information on warning lamps (Y page 252) and display messages which may be shown in the instrument cluster (Y page 223). i Only use wheels with the recommended tire sizes. Only then will ESP® function properly. 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.

Rengine 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 65). Driving safety systems If EBD has malfunctioned, the rear wheels can still 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 the brake system checked at a qualified specialist workshop. Observe information regarding indicator and warning lamps (Y page 250) as well as display messages (Y page 224). 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 182) and hill start assist (Y page 150). For further information, see "Driving tips" (Y page 168). PRE-SAFE® Brake General information i Observe the "Important safety notes" section (Y page 65). PRE-SAFE® Brake is only available in vehicles with DISTRONIC PLUS. For PRE-SAFE® Brake to assist you when driving, the radar sensor system must be operational. With the help of the radar sensor system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. PRE-SAFE® Brake can help you to minimize the risk of a collision with a vehicle ahead, and reduce the effects of such a collision. If PRESAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. PRE-SAFE® Brake cannot prevent a collision without your intervention. 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 also brake. Automatic emergency braking cannot prevent a collision. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action. 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.

Children in particular could accidentally press the electrical seat adjustment buttons and become trapped. There is a risk of injury. While moving the seats, make sure that your hands or other body parts do not get under the lever assembly of the seat adjustment system. G WARNING When you adjust a seat, you or other vehicle occupants could become trapped, e.g. on the seat guide rail. There is a risk of injury. Make sure when adjusting a seat that no one has any body parts in the sweep of the seat. G WARNING If head restraints are not installed and adjusted correctly, they cannot provide protection as intended. There is an increased risk of injury in the head and neck area, e.g. in the event of an accident or when braking. Always drive with the head restraints installed. Before driving off, make sure for every vehicle occupant that the center of the head restraint supports the back of the head at about eye level. G WARNING The seat belt does not offer the intended level of protection if the backrest is not in the upright 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 make sure that the seat is in the upright position. G WARNING According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. Thus, we strongly recommend that children be placed in the rear seat whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriately sized child restraint system or booster seat recommended for the size and weight of the child.

Replacing bulbs Important safety notes Xenon bulbs G DANGER Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of the Xenon bulb and touch the electrical contacts. There is a risk of fatal injury. Never touch the parts or the electrical contacts of the Xenon bulb. Always have work on the Xenon bulbs carried out at a qualified specialist workshop. If your vehicle is equipped with Xenon bulbs, you can recognize this by the following: the cone of light from the Xenon bulbs moves from the top to the bottom and back again when you start the engine. For this to be observed, the lights must be switched on before starting the engine. Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly. Other bulbs G WARNING Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you could burn yourself on these components. There is a risk of injury. Allow these components to cool down before changing a bulb. Do not use a bulb that has been dropped or if its glass tube has been scratched. The bulb may explode if: Ryou touch it is hot Ryou drop it Ryou scratch it Only operate bulbs in enclosed lamps designed for that purpose. Only install spare bulbs of the same type and the specified voltage. Marks on the glass tube reduce the service life of the bulbs. Do not touch the glass tube with your bare hands. If necessary, clean the glass tube when cold with alcohol or spirit and rub it off with a lint-free cloth. Protect bulbs from moisture during operation. Do not allow bulbs to come into contact with liquids. There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 121). Have the bulbs that you cannot replace yourself changed at a qualified specialist workshop. If you require assistance changing bulbs, consult a qualified specialist workshop. If the new bulb still does not light up, consult a qualified specialist workshop. Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly. Rit Overview: changing bulbs/bulb types You can change the following bulbs.

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions. i Read the information on qualified Climate control specialist workshops: (Y page 25). 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 the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control can only be operated when the engine is running. Optimum operation 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 141). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 89). This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly. i The integrated filter filters out most particles 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 dehumidification function of the climate control system may be activated automatically an hour after the SmartKey has been removed. The vehicle is then ventilated for 30 minutes. Overview of climate control systems 131 Canada only : To set the temperature, left (Y page 138) ; To defrost the windshield (Y page 139) = To switch the ZONE function on/off (Y page 139) ?

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions. i Read the information on qualified specialist workshops: (Y page 25). Notes on breaking-in a new vehicle Important safety notes 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. 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). RIdeally, for the first 1,000 miles (1,500 km), drive in program E (program C on AMG vehicles). RAvoid heavy loads, e.g. driving at full throttle, during this period. RChange gear in good time, before the tachometer needle is Ô of the way to the red area of the tachometer. RDo not manually shift to a lower gear to brake the vehicle. RIf possible, do not depress the accelerator pedal past the point of resistance (kickdown). ROnly select shift ranges 3, 2 or 1 when driving slowly, e.g. in mountainous terrain. After 1000 miles (1500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. Additional breaking-in notes for AMG vehicles: RDo not drive faster than 85 mph (140 km/h) for the first 1,000 miles (1,500 km). ROnly allow the engine to reach a maximum engine speed of 4,500 rpm briefly. RChange gear in good time. i You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced. i Always observe the respective speed limits. AMG vehicles with self-locking rear axle differential Your vehicle is equipped with a self-locking differential on the rear axle. To protect the differential on the rear axle, carry out an oil change after a breaking-in phase of 2,000 miles (3,000 km). This oil change prolongs the service life of the differential. Have the oil change carried out at a qualified specialist workshop. 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. Driving G WARNING Unsuitable footwear can hinder correct usage of the pedals, e.g.: Rshoes with thick soles Rshoes with high heels Rslippers There is a risk of an accident. Wear suitable footwear to ensure correct usage of the pedals. roads. You could otherwise damage the drive train. ! AMG vehicles: at low engine oil temperatures below 68 ‡ (+20 †), the maximum engine speed is restricted in order to protect the engine. To protect the engine and maintain smooth engine operation, avoid driving at full throttle when the engine is cold.

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 Driving tips 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 The ECO display gives you information on how economical your driving style is. The ECO display assists you in achieving the optimum driving style in terms of consumption, taking the actual and selected conditions into consideration. Your driving style can significantly influence the vehicle's consumption. Example: ECO display The ECO display consists of three bars: RAcceleration RConstant RCoasting The percent value is the average value of the three bars. The three bars and the mean value begin at the value of 50%. A higher percentage indicates a more economical driving style. The ECO display does not indicate the actual fuel consumption and a fixed percentage count in the ECO display does not indicate a fixed consumption figure. Apart from driving style, consumption is dependent on many factors such as, e.g.: Rload Rtire pressure start Rchoice of route Relectrical consumers switched on Rcold Z Driving and parking 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 167 Driving and parking 168 Driving tips These factors are not taken into consideration by the ECO display. The evaluation of your driving style is carried out using the following three categories: RAcceleration (evaluation of all acceleration processes): - The bar fills up: moderate acceleration, especially at higher speeds - The bar empties: sporty acceleration RConstant (assessment of driving behavior at all times): - The bar fills up: constant speed and avoidance of unnecessary acceleration and deceleration - The bar empties: fluctuations in speed RCoasting (assessment of all deceleration processes): - The bar fills up: anticipatory driving, keeping your distance and early release of the accelerator. The vehicle can coast without use of the brakes. - The bar empties: frequent braking i An economical driving style specially requires driving at moderate engine speeds. To achieve a higher value in the categories Acceleration and Constant: Robserve the gearshift recommendations. Rdrive in drive program E. i On long journeys at a constant speed, e.g. on the highway, only the bar for Constant will change. i The ECO display summaries the driving characteristics from the start of the journey to its completion. For this reason, the bars change dynamically at the beginning of the journey. On longer journeys, there are fewer changes. For more dynamic changes, carry out a manual reset. Further information on the ECO display (Y page 208). 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. Driving tips 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. 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. RBrake occasionally to remove any possible salt residue. Make sure that you do not endanger other road users when doing so. 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. 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. ! Vehicles with 4MATIC: function or performance tests may only be carried out on a 2-axle dynamometer. If you are planning to have the vehicle tested on such a dynamometer, contact an authorized Mercedes-Benz Center to obtain further information first. Otherwise, you could damage the drive train or the brake system. ! Vehicles with 4MATIC: as the ESP® system operates automatically, the engine and the ignition must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) while the parking brake is being tested on a brake dynamometer. Braking maneuvers triggered automatically by ESP® may seriously damage the brake system. ! Vehicles with 4MATIC: as the ESP® system operates automatically, the engine and the ignition system must be switched off (SmartKey in position 0 or 1 in the ignition lock or Start/Stop button in position 0 or 1) when: Rtesting the parking brake on a brake dynamometer. Ryou intend to have the vehicle towed with the front axle raised. Braking maneuvers triggered automatically by ESP® may seriously damage the brake system. If the brake system has only been subject to moderate loads, you should test the functionality of your brakes at regular intervals. To do so, press firmly on the brake pedal when driving at a high speed. This improves the grip of the brake pads. You can find a description of Brake Assist (BAS) on (Y page 66) or of BAS PLUS on (Y page 66). Z Driving and parking Wet roads 169 Driving and parking 170 Driving tips Mercedes-Benz recommends that you only have brake pads/linings installed on your vehicle which have been approved for Mercedes-Benz vehicles or which correspond to an equivalent quality standard. Brake pads/linings which have not been approved for Mercedes-Benz vehicles or which are not of an equivalent quality could affect your vehicle's operating safety. 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. High-performance brake system for AMG vehicles The high-performance brake system is installed only on the C 63 AMG. The high-performance brake system is designed for heavy loads. This may lead to noise when braking. This will depend on: RSpeed RBraking force REnvironmental conditions, such as temperature and humidity The wear and tear on individual brake system components, e.g. brake pads/linings or discs, depends on: Rthe individual driving style operating conditions For this reason, it is impossible to state a mileage that will be valid under all circumstances. An aggressive driving style will lead to high wear. You can obtain further information about this from your authorized Mercedes-Benz Center. 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. Keep this in mind, and Rthe adapt your driving and braking accordingly during this break-in period. Excessive heavy braking results in correspondingly high brake wear. Observe the brake wear warning lamp in the instrument cluster and note any brake status messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly. 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. Rbrake carefully. Ravoid Driving on flooded roads ! Do not drive through flooded areas. Check the depth of any water before driving through it. Drive slowly through standing water. Otherwise, water may enter the vehicle interior or the engine compartment. This can damage the electronic components in the engine or the automatic transmission. Water can also be drawn in by the engine's air suction nozzles and this can cause engine damage. Winter driving 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. 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 winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Winter operation" section (Y page 316). 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. i For more information on driving with snow chains, see (Y page 317). 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. Driving systems Cruise control Driving with summer tires Important safety notes Observe the notes in the "Winter operation" section (Y page 316). Cruise control maintains a constant road speed for you. It brakes automatically in order to avoid exceeding the set speed. On long and steep downhill gradients, especially if the vehicle is laden, you must select shift range 1, 2 or 3 in good time. 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 Slippery road surfaces 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. Z 171 Driving and parking Driving systems Driving and parking 172 Driving systems store any road speed above 20 mph (30 km/h). 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. Cruise control lever : To activate or increase speed ; To activate or reduce speed = To deactivate cruise control ? To activate at the current speed/last stored speed When you activate cruise control, the stored speed is shown in the multifunction display for five seconds. In the multifunction display, the segments between the stored speed and the maximum speed light up.

X Briefly press the cruise control lever up : or down ;. X Remove your foot from the accelerator pedal. Cruise control is activated. The vehicle automatically maintains the stored speed. i Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out. Cruise control maintains the stored speed on downhill gradients by automatically applying the brakes. Storing the current speed or calling up the last stored speed G WARNING If you call up the stored speed and it differs from the current speed, the vehicle accelerates or decelerates. If you do not know the stored speed, the vehicle could accelerate or brake unexpectedly. There is a risk of an accident. Pay attention to the road and traffic conditions before calling up the stored speed. If you do not know the stored speed, store the desired speed again. Briefly pull the cruise control lever towards you ?. X Remove your foot from the accelerator pedal.

You will see the Cruise Control Off message in the multifunction display for approximately five seconds. i When you switch off the engine, the last speed stored is cleared. DISTRONIC PLUS Important safety notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. DISTRONIC PLUS brakes automatically so that the set speed is not exceeded. On long and steep downhill gradients, especially if the vehicle is laden, you must select shift range 1, 2 or 3 in good time. 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 a slower-moving vehicle in front, your vehicle is braked in order to maintain the preset distance to the vehicle in front. G WARNING DISTRONIC PLUS does not react to: Rpeople or animals obstacles on the road, e.g. stopped or parked vehicles Roncoming and crossing traffic As a result, DISTRONIC PLUS may neither give warnings nor intervene in such situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rstationary G WARNING DISTRONIC PLUS cannot always clearly identify other road users and complex traffic situations. Z Driving and parking Setting a speed 173 174 Driving systems In such cases, DISTRONIC PLUS may: Driving and parking Rgive an unnecessary warning and then brake the vehicle Rneither give a warning nor intervene Raccelerate unexpectedly There is a risk of an accident. Continue to drive carefully and be ready to brake, in particular when warned to do so by DISTRONIC PLUS. G WARNING DISTRONIC PLUS brakes your vehicle with up to 40% of the maximum braking force. If this braking force is insufficient, DISTRONIC PLUS warns you visually and audibly. There is a risk of an accident. In such cases, apply the brakes yourself and try to take evasive action. ! If DISTRONIC PLUS or the HOLD function is activated, the vehicle brakes automatically in certain situations. To prevent damage to the vehicle, deactivate DISTRONIC PLUS and the HOLD function in the following or other similar situations: Rwhen Rin towing the vehicle the car wash If you fail to adapt your driving style, DISTRONIC PLUS can neither reduce the risk of accident nor override the laws of physics. DISTRONIC PLUS cannot take into account the road, traffic and weather conditions. DISTRONIC PLUS is only an aid.

Do not use DISTRONIC PLUS: 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 DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving on a different line. In particular, the detection of obstacles can be impaired if: Rdirt on the sensors or anything else covering the sensors Rsnow or heavy rain Rinterference by other radar sources Rstrong radar reflections, for example, in parking garages If DISTRONIC PLUS no longer detects a vehicle in front, DISTRONIC PLUS may unexpectedly accelerate the vehicle to the stored speed. This speed may: Rbe too high if you are driving in a filter lane or an exit lane Rbe so high when driving in the right-hand lane that you overtake vehicles in the lefthand lane Rbe so high when driving in the left-hand lane that you overtake vehicles in the right-hand lane If there is a change of drivers, advise the new driver of the speed stored. If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control in the speed range between 20 mph (Canada: 30 km/h) and 120 mph (Canada: 200 km/h). If a vehicle is driving in front of you, it operates in the speed range between 0 mph (0 km/h) and 120 mph (Canada: 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.

Your vehicle pulls away and adapts its speed to that of the vehicle in front. Driving If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control. If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle. In this way, the distance you have selected is maintained. If DISTRONIC PLUS detects that the vehicle in front is driving faster, it accelerates your vehicle, but only up to the speed you have stored. Changing lanes If you change to the passing lane, DISTRONIC PLUS supports you when: Ryou are driving faster than 40 mph (60 km/h) RDISTRONIC PLUS is maintaining the distance to a vehicle in front Ryou switch on the appropriate turn signal RDISTRONIC PLUS does not detect a danger of collision If these conditions are fulfilled, your vehicle is accelerated. Acceleration will be interrupted if changing lanes takes too long or if the distance between your vehicle and the vehicle in front becomes too small. i When changing lanes, DISTRONIC PLUS monitors the left lane on left-hand drive vehicles and the right lane on right-hand drive vehicles. Stopping X G WARNING When leaving the vehicle, even if it is braked only by DISTRONIC PLUS, it could roll away if: Rthere is a malfunction in the system or in the voltage supply. RDISTRONIC PLUS has been deactivated with the cruise control lever, e.g. by a vehicle occupant or from outside the vehicle. 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. If you wish to exit the vehicle, always turn off DISTRONIC PLUS and secure the vehicle against rolling away. Deactivating DISTRONIC PLUS (Y page 179). If DISTRONIC PLUS detects that the vehicle in front is stopping, it brakes your vehicle until it is stationary. Once your vehicle is stationary, it remains stationary and you do not need to depress the brake. i Depending on the specified minimum distance, your vehicle will come to a standstill at a sufficient distance behind the vehicle in front. The specified minimum distance is set using the control on the cruise control lever. You will see a warning message in the multifunction display if DISTRONIC PLUS is activated and: Rthe driver's door is open and the driver's seat belt is unfastened. Rthe engine is switched off.

Parking Guidance may not detect flat curbs Parking tips: ROn narrow roads, drive as close to the parking space as possible. RParking spaces that are littered, overgrown or partially occupied by trailer drawbars might be identified incorrectly or not at all. RSnowfall or heavy rain may lead to a parking space being measured inaccurately. RPay attention to the PARKTRONIC (Y page 186) warning messages during the parking procedure. RWhen transporting a load which protrudes from your vehicle, you must not use Parking Guidance. RNever use Parking Guidance with snow chains or an emergency spare wheel mounted. RMake sure that the tire pressures are always correct. This has a direct effect on the steering instructions. 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. In some cases, Parking Guidance may guide you too far or not far enough into a parking space. In some cases, it may also lead you across or onto the curb. If necessary, cancel the parking procedure with Parking Guidance. ! 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. : Detected parking space on the left ; Parking symbol = Detected parking space on the right Parking Guidance is automatically activated when you drive forwards.

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. ATTENTION ASSIST helps you during long, monotonous journeys, such as on highways. It is active in the range between 50 mph (80 km/h) and 112 mph (180 km/h). If ATTENTION ASSIST detects typical indicators of fatigue or increasing lapses in concentration on the part of the driver, it suggests you take a break. ATTENTION ASSIST assesses your level of fatigue or lapses in concentration by taking the following criteria into account: Ryour personal driving style, e.g. steering characteristics Rjourney details, e.g. time of day and length of journey The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: 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 50 mph (80 km/h) or faster than 112 mph (180 km/h) Rif you are currently using COMAND or making a telephone call with it Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed Warning and display messages in the multifunction display X Activate ATTENTION ASSIST using the onboard computer (Y page 214). If ATTENTION ASSIST is active, you will be warned no sooner than 20 minutes after your journey has begun. You then hear an intermittent warning tone twice and the Attention Assist: Drowsiness detected message appears in the multifunction display. X If necessary, take a break. X Press the a button to confirm the message. On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break, you will be warned again after 15 minutes at the earliest. The precondition for this is that ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration. 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. The assistance graphic shows the é symbol when ATTENTION ASSIST is deactivated (Y page 213). Ryou Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 193) and Lane Keeping Assist (Y page 194). Driving systems General notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from a speed of approximately 20 mph (30 km/h). 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 lanes, you will also receive a visual and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes. For Blind Spot Assist to assist you, the radar sensor system must be operational. Important safety notes 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. Any unauthorized modification to this device could void the user’s authority to operate the equipment. Monitoring range of the sensors In particular, the detection of obstacles can be impaired if: Rdirt on the sensors or anything else covering the sensors Rpoor visibility, e.g. due to fog, heavy rain, snow or spray Rnarrow vehicles, e.g. motorcycles or bicycles Rthe road has very wide lanes Rthe road has narrow lanes Ryou are not driving in the middle of the lane Rthere are barriers or similar lane borders Vehicles in the monitoring range are then not indicated. 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. i USA only: This device has been approved by the FCC as a "Vehicular Radar System". The radar sensor is intended for use in an automotive radar system only. Removing, tampering with, or altering the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Blind Spot Assist monitors the area up to 10 ft (3 m) behind your vehicle and directly next to your vehicle, as shown in the diagram. 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 driving at the inner edge of their lanes. Z Driving and parking Blind Spot Assist 193 194 Driving systems Due to the nature of the system: Driving and parking Rwarnings may be issued in error when driving close to crash barriers or similar solid lane borders. Rthe warning is canceled when driving for an extended period next to long vehicles, such as trucks. The two radar sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free of dirt, ice or slush in the vicinity of the sensors. The sensors must not be covered, for example by cycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the sensors checked at a qualified specialist workshop. Blind Spot Assist may otherwise not work properly. Indicator and warning display Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in the monitoring range are then not indicated. 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). The yellow indicator lamp goes out if reverse gear is engaged. In this event, Blind Spot Assist is no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the corresponding turn signal, a double warning tone sounds. Red warning lamp : flashes. If the turn signal remains on, vehicles detected are indicated by the flashing of red warning lamp :. There are no further warning tones.

This warning is always emitted when a vehicle enters the General notes Lane Keeping Assist monitors the area in front of your vehicle with camera :, which is mounted at the top of the windshield. Lane Keeping Assist detects lane markings on the road and warns you before you leave your lane unintentionally. Driving systems 195 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. : Active Lane Keeping Assist camera If you select km on the on-board computer in the Display Unit Speed-/Odometer function (Y page 215), Lane Keeping Assist is active starting at a speed of 60 km/h. If the miles display unit is selected, the assistance range begins at 40 mph. 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 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. 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 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 lane Switching on Lane Keeping Assist X Switch on Active Lane Keeping Assist using the on-board computer; to do so, select Standard or Adaptive(Y page 214).

Active Driving Assistance package General notes The Active Driving Assistance package consists of DISTRONIC PLUS (Y page 173), Active Blind Spot Assist (Y page 196) and Active Lane Keeping Assist (Y page 199). Active Blind Spot Assist General notes Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle which are behind the driver. 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. To support the coursecorrecting brake application, Active Blind Spot Assist uses the forward-facing radar sensor system. The free space is then evaluated in the direction of travel and to the side before a course-correcting brake application is initiated. Active Blind Spot Assist supports you from a speed of approximately 20 mph (30 km/h). For Active Blind Spot Assist to assist you when driving, the radar sensor system must be operational. Important safety notes Active Blind Spot Assist is only an aid. It does not detect all traffic situations and road users and is no substitute for attentive driving. Always ensure that there is sufficient distance to the side for other road users and obstacles. G WARNING Active 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, Active Blind Spot Assist may neither give warnings nor intervene in such situations. There is a risk of an accident. Always observe the traffic conditions carefully, and maintain a safe lateral distance. i USA only: Driving systems Active Blind Spot Assist may not detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late.

Any unauthorized modification to this device could void the user's authority to operate the equipment. Monitoring range of the sensors G WARNING Active Blind Spot Assist does not detect all traffic situations and road users. There is a risk of an accident. Always make sure that there is sufficient distance on the side for other traffic or obstacles. In particular, the detection of obstacles can be impaired if: Rdirt on the sensors or anything else covering the sensors Rpoor visibility, e.g. due to rain, snow or spray Vehicles in the monitoring range are then not indicated. 197 Active Blind Spot Assist monitors the area up to 10 ft (3 m) behind your vehicle and directly next to your vehicle, as shown in the diagram. For this purpose, Active Blind Spot Assist uses radar sensors in the rear bumper. 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 driving at the inner edge of their lanes. Due to the nature of the system: Rwarnings may be issued in error when driving close to crash barriers or similar solid lane borders. Rthe warning is canceled when driving for an extended period next to long vehicles, such as trucks. Two Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers respectively. An additional radar sensor is located behind the cover in the radiator grill. Make sure that the sensors and areas around them are free of dirt, ice or slush. The rear sensors must not be covered, for example by cycle racks or overhanging cargo. Following a severe impact or in the event of damage to Z 198 Driving systems Driving and parking the bumpers, have the function of the sensors checked at a qualified specialist workshop. Blind Spot Assist may otherwise not work properly. Indicator and warning display Active Blind Spot Assist is not active at speeds below approximately 20 mph (30 km/h). Vehicles in the monitoring range are then not indicated. Visual and acoustic collision warning When 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 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 G WARNING : Yellow indicator lamp/red warning lamp When Active Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up yellow at speeds of up to 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and Active Blind Spot Assist is operational. 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). The yellow indicator lamp goes out if reverse gear is engaged. In this event, Active Blind Spot Assist is no longer active. The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light. 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 application. Always maintain a safe distance at the sides. In very rare cases, the system may make an inappropriate brake application. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate. 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. The course-correcting brake application is available in the speed range between 20 mph (30 km/h) and 120 mph (200 km/h). If a course-correcting brake application occurs, red warning lamp : flashes in the exterior mirror and the following is shown in the multifunction display, for example: Driving systems 199 Either a very slight course-correcting brake application, or none at all, may occur if: 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. Switching on Active Blind Spot Assist X Make sure that Active Blind Spot Assist (Y page 214) is activated in the on-board computer. 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 and then turn yellow. Active Lane Keeping Assist General notes Active Lane Keeping Assist monitors the area in front of your vehicle by means of a camera : mounted at the top of the windshield. Active Lane Keeping Assist detects lane markings on the road and warns 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. : Active Lane Keeping Assist camera If you select km on the on-board computer in the Display Unit Speed-/Odometer function (Y page 215), 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. 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. 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. Active Lane Keeping Assist cannot continuously keep your vehicle in its lane. 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.

Lane-correcting brake application 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. G WARNING Active Lane Keeping Assist does not detect traffic conditions or road users. In very rare cases, the system may make an inappropriate brake application, e.g. after intentionally driving over a solid lane marking. There is a risk of an accident. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction. Always make sure that there is sufficient distance on the side for other traffic or obstacles. 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. This function is available in the range between 40 mph and 120 mph (60 km/h and 200 km/h). A lane-correcting brake application can only be made after driving over a solid, recognizable lane marking. Before this, a warning must be given by means of intermittent vibration in the steering wheel. Driving systems i A further lane-correcting brake application can only occur after your vehicle has returned to the original lane.

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions. i Read the information on qualified specialist workshops: (Y page 25). Tires with run-flat characteristics: Rpay attention to the information and warning notices on MOExtended tires (tires with run-flat characteristics). Accessories that are not approved for your vehicle by Mercedes-Benz or that are not being used correctly can impair operating safety. Before purchasing and using non-approved accessories, visit a qualified specialist workshop and inquire about: Rsuitability Rlegal Important safety notes Wheels and tires G WARNING If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of an accident. Always replace wheels and tires with those that fulfill the specifications of the original part. When replacing wheels, make sure to use the correct: Rdesignation Rmodel When replacing tires, make sure to use the correct: Rdesignation Rmanufacturer Rmodel G WARNING A flat tire severely impairs the driving, steering and braking characteristics of the vehicle. There is a risk of accident. Tires without run-flat characteristics: Rdo not drive with a flat tire. replace the flat tire with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop. Rimmediately stipulations recommendations Information on the dimensions and types of wheels and tires for your vehicle can be found in the "Wheel/tire combinations" section (Y page 342). Information on air pressure for the tires on your vehicle can be found: Rfactory 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 Modification work on the brake system and wheels is not permitted. The use of wheel spacers or brake dust shields is not permitted. This invalidates the general operating permit for the vehicle. i Further information on wheels and tires can be obtained at any qualified specialist workshop. Operation Information on driving RIf the vehicle is heavily loaded, check the tire pressures and correct them if necessary. RWhile driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop. RWhen 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. Regular checking of wheels and tires 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. RRegularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as: - cuts in the tires - punctures - tears in the tires - bulges on tires - deformation or severe corrosion on wheels RRegularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 315). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface. RAll wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems. RRegularly check the pressure of all the tires including the emergency spare wheel or the spare wheel, particularly prior to long trips, and correct the pressure as necessary (Y page 318). Observe the notes on the emergency spare wheel (Y page 346). 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 RM+S tires: â in (3 mm) tires: ã in (4 mm) Z 315 Wheels and tires Operation Wheels and tires 316 Winter operation For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached. Observe the notes on the emergency spare wheel (Y page 346). Treadwear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once the tread depth is approximately á in (1.6 mm). If this is the case, the tire is so worn that it must be replaced. MOExtended tires (tires with run-flat properties) Bar indicator : for tread wear is integrated into the tire tread. Selecting, mounting and replacing 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 301). ROnly mount tires of the correct size onto the wheels. RAfter mounting new tires, break them in at moderate speeds for the first 60 miles (100 km), as 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. 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 in the event of a flat tire can be found in the "Breakdown assistance" section (Y page 301). Winter operation Points to remember Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 338). 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. 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 Winter operation 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 provide 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 M+S tires: Check the tire pressures (Y page 321). Vehicles for Canada: restart the tire pressure loss warning system (Y page 321). X Vehicles for USA: restart the tire pressure monitor (Y page 322). X X For more information on driving with the emergency spare wheel, see (Y page 346). 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. ! On some tire sizes there is not enough space for snow chains. To avoid damage to the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and wheels". ! Vehicles with steel wheels: if you wish to mount snow chains on steel wheels, make sure that you remove the respective wheels' hubcaps first. The hubcaps may otherwise be damaged. 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 342). 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). i You may wish to deactivate ESP®(Y page 68) when pulling away with snow chains installed. You can thereby allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). For more information on driving with the emergency spare wheel, see (Y page 346). Z Wheels and tires 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. 317 318 Tire pressure Tire pressure Tire pressure specifications G WARNING Underinflated or overinflated tires pose the following risks: Wheels and tires 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. Follow recommended tire inflation pressures and check the pressure of all the tires including the spare wheel: Rmonthly, at least Rif the load changes Rbefore beginning a long journey Runder different operating conditions, e.g. off-road driving If necessary, correct the tire pressure. : Recommended tire pressures Option 2) Tire pressure table on the inside of the fuel filler flap. The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. i Specifications shown in the examples of tire pressure tables are for illustration purposes only. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. Tire pressure specifications applicable to your vehicle are located in your vehicle's tire pressure table. The recommended tire pressures for the tires mounted at the factory can be found on the labels described here. 1.) Tire and Loading Information placard on the B-pillar on the driver's side of the vehicle (Y page 326). 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. i The specifications given on the following Tire and Loading Information placard are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressures applicable to your vehicle can be found on the Tire and Loading Information placard on your vehicle. Example: tire pressure table for all tires permitted for this vehicle by the factory 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. Tire pressure 319 Option 3) The tire pressure for the emergency/collapsible spare wheel (depending on vehicle equipment) can be found: Example: tire pressure table with tire dimensions Some tire pressure tables show only the rim diameters instead of the full tire size, e.g. R18. The rim diameter is part of the tire size and can be found on the tire sidewall (Y page 332). in yellow on the rim of the emergency/collapsible spare wheel Rin the "Wheel and tire combinations" section (Y page 342) in this Operator's Manual Ron the Tire and Loading Information placard on the B-pillar on the driver's side 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 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: Rif you want to drive with an increased load and/or Rif you want to drive at higher road speeds. i 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 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. To test tire pressure, use a suitable tire pressure gauge. The outer appearance of a tire does not permit any reliable conclusion Z Wheels and tires Rprinted 320 Tire pressure about the tire pressure. On vehicles equipped with the electronic tire pressure monitoring system, the tire pressure can be checked using 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: Wheels and tires 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 and 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. Observe the recommended tire pressures for cold tires: Ron the Tire and Loading Information placard on the B-pillar on the driver's side the tire pressure table on the inside of the fuel filler flap Rprinted in yellow on the rim of the emergency/collapsible spare wheel (depending on vehicle equipment) Rin Underinflated or overinflated tires Underinflation G WARNING Tires with pressure that is too low can overheat and burst as a consequence. In addition, they also suffer from excessive and/ or irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too low in all the tires, including the spare wheel. Underinflated tires may: Rwear quickly and unevenly Rhave an adverse effect on fuel consumption Roverheat, leading to tire defects an adverse effect on handling characteristics Rhave Overinflation G WARNING Tires with excessively high pressure can burst because they are damaged more easily by road debris, potholes etc. In addition, they also suffer from irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too high in all the tires, including the spare wheel. Overinflated tires may: Rhave an adverse effect on handling characteristics Rwear quickly and unevenly Rbe more susceptible to damage Rhave an adverse effect on ride comfort Rincrease the braking distance Maximum tire pressures Never exceed the maximum permissible tire inflation pressure. Always observe the Tire pressure recommended tire pressure for your vehicle when adjusting the tire pressure (Y page 318). 321 If necessary, increase the tire pressure to the recommended value (Y page 318). X If the tire pressure is too high, release air by pressing down the metal pin in the valve using 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 Tire pressure loss warning system (Canada only) pressure i The actual values for tires are vehicle- specific and may deviate from the values in the illustration.

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 information" section 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 on the B-pillar on the driver's side of your vehicle. X General notes While the vehicle is in motion, the tire pressure loss warning system monitors the set tire pressure using the rotational speed of the wheels. This enables the system to detect significant pressure loss in a tire. If the speed of rotation of a wheel changes as a result of a loss of pressure, a corresponding warning message will appear in the multifunction display. You can recognize the tire pressure loss warning by the Run Flat Indicator Active Press 'OK' to Restart message which appears in the Service menu of the multifunction display. Information on the message display can be found in the "Restarting the tire pressure loss warning system" section (Y page 322). Important safety notes The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 318). The tire pressure loss warning does not replace the need to regularly check the tire pressure. An even loss of pressure on several tires at the same time cannot be detected by the tire pressure loss warning system. 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.

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 corresponding sensors are installed on all wheels. Information on tire pressures is displayed in the multifunction display. After a few minutes Example: current tire pressure display For information on the message display, refer to the "Checking the tire pressure electronically" section (Y page 324). Important safety notes G WARNING Each tire, including the spare (if provided), should be checked at least once a month 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 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 illuminates, 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 323 pressure, even if 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 if 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. Wheels and tires of driving, the current tire pressure of each tire is shown in the Service menu of the multifunction display. Tire pressure 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 318). 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 325). 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 318). Z 324 Tire pressure 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: Wheels and tires 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. i In addition to the warning lamp, a message appears in the multifunction display. Further information can be found on (Y page 242). 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 onboard 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. Checking the tire pressure electronically Make sure that the SmartKey is in position 2 in the ignition lock (Y page 147). X Press the = or ; button on the steering wheel to select the Service menu. X Press the 9 or : button to select Tire Pressure. X Press the a button. The current tire pressure of each tire is shown in the multifunction display. X If the vehicle has been parked for over 20 minutes, the Tire pressures will be displayed after driving a few minutes message appears. After a teach-in process, the tire pressure monitor automatically detects new wheels or new sensors. As long as a clear allocation of the tire pressure value to the individual wheels is not possible, the Tire Pressure Monitor Active display message is shown instead of the tire pressure display. The tire pressures are already being monitored. i If a spare wheel/emergency spare wheel is mounted, the system may continue to show the tire pressure of the wheel that has been removed for a few minutes. If this occurs, note that the value displayed for the position where the spare tire is mounted is not the same as the spare wheel/emergency spare wheel's current tire pressure. Tire pressure X If the tire pressure monitor detects a pressure loss in one or more tires, a warning message is shown in the multifunction display and the yellow tire pressure monitor warning lamp comes on. RIf the 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 Warning 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 242). i 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. Make sure that the tire pressure is correct on all four wheels.

The gross weight of all vehicle occupants, load, luggage and trailer load/noseweight (if applicable) must not exceed the specified value. Loading the vehicle i The specifications shown on the Tire and Loading Information placard in the illustration are examples. The number of seats is vehicle-specific and can differ from the details shown. The number of seats in your vehicle can be found on the Tire and Loading Information placard. Maximum number of seats : indicates the maximum number of occupants allowed to travel in the vehicle. This information can be found on the Tire and Loading Information placard. 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 lbs passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1 400 - 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. X Step 6 (if applicable): If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Refer to this Operator's Manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (Y page 329). X Determining the correct load limit Step-by-step instructions The following steps have been developed as required of all manufacturers under Title 49, Code of U.S. Federal Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle Safety Act of 1966". 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.

Details can be found on the vehicle identification plate on the B-pillar on the driver's side of the vehicle (Y page 326). Permissible gross vehicle weight: 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: 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. the trailer load/noseweight is included in the load along with occupants and luggage. The trailer load/noseweight is usually approximately 10% of the gross weight of the trailer and its load. Your Mercedes-Benz has been designed primarily to carry passengers and their luggage. Mercedes-Benz does not recommend towing a trailer with your vehicle. Maximum load rating 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 326). Trailer load/noseweight The trailer load/noseweight affects the gross weight of the vehicle. If a trailer is attached, Z Wheels and tires The higher the weight of all the occupants, the smaller the maximum load for luggage. Further information can be found under "Towing a trailer" (Y page 329). 330 Uniform Tire Quality Grading Standards i The actual values for tires are vehicle- specific and may deviate from the values in the illustration. Where applicable, the tire grading information can be found on the tire sidewall between the tread shoulder and maximum tire width. For example: i The actual values for tires are vehicle- specific and may deviate from the values in the illustration. Maximum tire load : is the maximum permissible weight for which the tire is approved. Treadwear Traction Temperature 200 AA A All passenger car tires must conform to the statutory safety requirements in addition to these grades. Wheels and tires Treadwear 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 :, tire traction ; and heat resistance =. All tires sold in North America are provided with the corresponding quality class mark on the sidewall of the tire, even though these regulations do not apply to Canada. 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. The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on a wet surface as measured under controlled conditions on Tire labeling represent higher levels of performance on the laboratory test wheel than the minimum required by law. Tire labeling Overview of tire labeling The following markings are on the tire in addition to the tire name (sales designation) and the manufacturer's name: ! Avoid wheelspin. This can lead to damage to the drive train. 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. These 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 : Uniform Tire Quality Grading Standard (Y page 335) ; DOT, Tire Identification Number (Y page 334) = Maximum tire load (Y page 329) ? Maximum tire pressure (Y page 320) A Manufacturer B Tire material (Y page 335) C Tire size designation, load-bearing capacity and speed index (Y page 332) D Load index (Y page 334) E Tire name i Tire data is vehicle-specific and may deviate from the data in the example. Z Wheels and tires 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 the freezing point. Mercedes-Benz recommends a minimum tread depth of ã in (4 mm) for all four winter tires (Y page 316) to maintain normal driving characteristics in winter. Winter tires can reduce the braking distance on snow-covered surfaces in comparison with summer tires. Stopping distance, however, is still considerably greater than when the road is not covered with ice or snow. Take appropriate care when driving. 331 332 Tire labeling Tire size designation, load-bearing capacity and speed rating : Tire width ; Nominal aspect ratio in % = Tire code Wheels and tires ? Rim diameter A Load bearing index B Speed rating i Tire data is vehicle-specific and may deviate from the data in the example. 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 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 326). 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 329). For further information on the load bearing index, see "Load index" (Y page 334). Speed rating: speed rating B specifies the approved maximum speed of the tire. 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. Regardless of the speed rating, always observe the speed limits. Drive carefully and Tire labeling Summer tires (300 km/h) must include "ZR", and the service specification must be given in parentheses. Example: 275/40 ZR 18 (99 Y).

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 301). Rotating the wheels Wheels and tires 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 338). The wear patterns on the front and rear tires differ, depending on the operating conditions. 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. Do not change the direction of wheel rotation. Clean the contact surfaces of the wheel and the brake disc thoroughly every time a wheel is rotated. Check the tire pressures. Information on changing tires and mounting the spare wheel (Y page 338). Direction of rotation 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. Cleaning the wheels G WARNING The water jet from a circular jet nozzle (dirt blasters) can cause invisible exterior damage to the tires or chassis components.
