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 Please read the information on qualified specialist workshops (Y page 24). 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 Rchild restraint systems RLATCH-type (ISOFIX) child seat anchors Additional protection is provided by: 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 deployed in an accident. RNECK-PRO G WARNING 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 See "Children in the vehicle" (Y page 53) for more information on infants and children traveling with you in the vehicle and restraints for infants and children. SRS (Supplemental Restraint System) 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 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 is not lit while the engine is running . G WARNING The SRS self-check has detected a malfunction if the 6 SRS warning lamp: Rdoes not come on at all to go out approximately 4 seconds after the engine was started Rcomes on after the engine was started or while driving For your safety, Mercedes-Benz strongly recommends that you have the system checked as soon as possible at an authorized Mercedes-Benz Center. Otherwise the SRS may not be activated when it is needed in an accident, which could result in serious or fatal injury. The SRS might also deploy unexpectedly and unnecessarily which could also result in injury. In addition, improper 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. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: Call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details. Rfails 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 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 Z 37 Safety Occupant safety Safety 38 Occupant safety 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 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 To reduce the risk of injuries during front air bag inflation, the driver and front-passenger must always be seated correctly and have their seat belts fastened accordingly. 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. Since 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 properly fastened in a position that is as upright as possible with your back against the seat 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) or more. 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 by the rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when 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 injuries or death should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized child restraint, infant 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. G WARNING Accident research shows that the safest place for children in an automobile is in a rear seat. A side impact air bag related injury may occur if occupants, especially children, are not properly seated or restrained when next to a side impact air bag which needs to deploy rapidly in a side impact in order to do its job. To help avoid the possibility of injury, please follow these guidelines: (1) (2) Always sit as upright as possible and use the seat belts properly. Make sure that children 12 years old and under use an appropriately sized child restraint, infant restraint, or booster seat recommended for the size and weight of the child. Always wear seat belts properly. The air bags are only deployed if the air bag control unit detects the need for deployment. Only in the event of such a situation will they provide their supplemental protection. The driver and passenger should always wear their seat belts. Otherwise, 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 passengers 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. Front air bags The front air bags increase protection for the driver's and front-passenger's head and chest. 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: Rin the event of certain frontal impacts the system determines that air bag deployment can offer additional protection to that provided by the seat belt Rif the seat belt is fastened Rindependently of other air bags in the vehicle Rif Z 39 Safety Occupant safety Safety 40 Occupant safety 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. The deployment of the 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 42). 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 deploy if: Rthe system, based on the OCS weight sensor readings, detects that the frontpassenger seat is occupied. Rthe 45 indicator lamp in the center console is not lit, (Y page 42). Rthe air bag control unit predicts a high impact severity. Driver's knee bag Driver's knee bag : provides additional protection for the driver against: Rknee injuries injuries Rlower leg injuries Driver's knee bag : deploys below the steering wheel. During a frontal impact, if 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. The driver's knee bag : operates best in conjunction with a properly positioned and fastened seat belt. Rthigh Side impact air bags G WARNING The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers. Improper repair work on the doors or the modification or addition of components to the doors create a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment. Work on the doors must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. 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. 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 If the OCS detects that the front-passenger seat is not occupied and the front-passenger seat belt is not fastened (the belt tongue is not engaged in the seat belt buckle), the side impact air bag on the front-passenger side will not deploy. The side impact air bag on the front-passenger 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. Front side impact air bags : and rear side impact air bags ; deploy next to the outer seat cushions. The side impact air bags are deployed: Ron the side on which an impact occurs the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact Rindependently of seat belt use Rindependently of the front air bags Rindependently of the ETDs Side impact air bags will not deploy in side impacts which do not exceed the system's preset deployment thresholds for lateral acceleration/deceleration. You will then be protected by the fastened seat belt. Rat 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 seat belt use Z 41 Safety Occupant safety Safety 42 Occupant safety Rindependently Rindependently Rindependently Rindependently of the front air bags 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. You will then be protected by the fastened seat belt. If the OCS detects that the front-passenger seat is not occupied and the front-passenger seat belt is not fastened (the belt tongue is not engaged in the seat belt buckle), the pelvis air bag on the front-passenger side will not deploy. The pelvis 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. Window curtain air bags The window curtain air bags enhance the level of protection for the head, but not chest or arms, of the vehicle occupants on the side of the vehicle on which the impact occurs. The window curtain air bags are integrated into the side of the roof frame and deploy in the area from the A-pillar to the C-pillar. of seat belt use of the front air bags Window curtain air bags : will not deploy in impacts with deceleration rates which do not exceed the system's preset deployment thresholds for vehicle deceleration or acceleration. You will then be protected by the fastened seat belt. Occupant Classification System (OCS) How the occupant classification system works The Occupant Classification System (OCS) categorizes the occupant on the frontpassenger seat by means of a weight sensor. The front-passenger front air bag is deactivated automatically for certain weight categories. The 45 indicator lamp shows you the current status. If the 45 indicator lamp is illuminated, the front-passenger front air bag is deactivated. 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 If the front-passenger's weight is transferred to another object in the vehicle (e.g. by leaning on armrests), OCS may not be able to approximate the occupant's weight category. If the front-passenger seat, the seat cover or the seat cushion are damaged, have the necessary repair work carried out at an authorized Mercedes-Benz Center. Rin Window curtain air bags : are deployed: Ron the side on which an impact occurs the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact Rregardless of whether the front-passenger seat is occupied Rat For safety reasons, Mercedes-Benz recommends that you only use seat accessories which have been approved by Mercedes-Benz. Both the driver and the passenger should always use the 45 indicator lamp as an indication of whether or not the passenger is properly positioned. G WARNING 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. 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 For further information, see "Air bag display messages" (Y page 221). 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 Z 43 Safety Occupant safety Safety 44 Occupant safety 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. A 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. RIf you place a child in a forward-facing child restraint on the front-passenger seat: - move the seat as far back as possible - use the proper child restraint recommended for the age, size and weight of the child - secure child restraint with the vehicle's seat belt according to the child seat manufacturer's instructions RFor children larger than the typical 12month-old child, the front-passenger front air bag may or may not be activated. If the driver's air bag deploys, this does not mean that the front-passenger front air bag also has to deploy. The OCS may have detected that the seat: Rwas empty or occupied by a person with a weight of up to or less than that of a typical 12-month-old child seated in a standard child restraint Rwas occupied by a small individual, such as a young teenager or a small adult Rwas occupied by a child in a child restraint system, whose weight is greater than that of a typical 12-month-old child. These are examples of when the OCS deactivates the front-passenger front air bag. Deactivation takes place although the collision fulfills the criteria for deploying the driver's air bag. Occupant safety 45 System self-test The 45 indicator lamp illuminates when you: the SmartKey to position 1 or 2 in the ignition lock Ron vehicles with KEYLESS-GO, press the Start/Stop button once or twice If an adult occupant is properly sitting on the passenger seat and the OCS classifies the occupant as an adult, the 45 indicator lamp illuminates and goes out again after approximately 6 seconds. If the seat is not occupied and the OCS classifies the front passenger seat as being unoccupied, the 45 indicator lamp will illuminate and not go out. If the SmartKey has been removed from the ignition lock or is in position 0, indicator lamp 45: does not light up. G WARNING If the red 6 SRS warning lamp in the instrument cluster and the 45 indicator lamp light up simultaneously, the OCS is malfunctioning. The front passenger front air bag will be deactivated in this case. Have the system checked by qualified technicians as soon as possible. Contact an authorized Mercedes-Benz Center. Only have the seat repaired or replaced at an authorized Mercedes-Benz Center. In order to ensure proper operation of the air bag system and OCS: RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RWhen seated, a passenger should not position him/herself in such a way as to cause the passenger's weight to be lifted from the seat cushion as this may result in the OCS being unable to correctly approximate the passenger's weight category. RRead and observe all warnings in this chapter. G WARNING If the 4 5 indicator lamp does not illuminate, the system is not functioning. You must contact an authorized Mercedes-Benz Center before seating any child on the front passenger seat. For more information, see "Problems with the Occupant Classification System" (Y page 46). G WARNING Never place anything between seat cushion and child seat (e.g. a pillow), since it reduces the effectiveness of the OCS. The underside and rear side child restraint system must be placed entirely on the seat cushion and the backrest of the front-passenger seat backrest. If necessary, adjust the tilt of the passenger seat backrest. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protection for the child. Follow the manufacturer's instructions for installation of child restraint systems.

In the event of a rear collision of a certain severity, the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats are moved forwards and upwards. This provides better head support. G WARNING Do not attach any objects (e.g. a coat hanger) to the NECK-PRO head restraints/NECK-PRO luxury head restraints. Otherwise, the NECKPRO head restraints/NECK-PRO luxury head restraints may not function properly and in the event of a rear-end collision may not offer the protection they are designed to provide. G WARNING Seat or head restraint covers can cause a malfunction when the NECK-PRO head restraints/NECK PRO luxury head restraints are activated or when the side impact air bags or pelvis air bags are deployed, or they can prevent this completely. The NECK-PRO head restraints/NECK PRO luxury head restraints or side impact air bags/pelvis air bags can therefore not provide the intended protection. Do not use any seat or head restraint covers. If the NECK-PRO head restraints/NECK-PRO luxury head restraints have been triggered in an accident, reset the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats (Y page 47). Otherwise, the additional protection will not be available in the event of another rear-end collision. NECK-PRO head restraints/NECK-PRO luxury head restraints that have been triggered are moved forwards and can no longer be adjusted. G WARNING For your protection, drive only with properly positioned head restraints. Adjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation. Resetting triggered NECK-PRO head restraints/NECK-PRO luxury head restraints Important safety notes G WARNING For reasons of safety, have the NECK-PRO head restraints/NECK-PRO luxury head restraints checked at an authorized Mercedes-Benz Center after a rear-end collision. G WARNING When pushing back the NECK-PRO head restraint cushion, make sure your fingers do not become caught between the head restraint cushion and the cover. Failure to observe this could result in injuries. NECK-PRO head restraints i Resetting the NECK-PRO head restraints requires a lot of strength.

Seat belts Important safety notes The use of seat belts and infant and child restraint systems is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces. Even where this is not the case, all vehicle occupants should have their seat belts fastened when the vehicle is in motion. i For further information on infants and children traveling in the vehicle and on infant and child restraint systems, see "Children in the vehicle" (Y page 53). G WARNING Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts. Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed. Occupant safety G WARNING Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body. G WARNING Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time. G WARNING Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced and their anchoring points must also be checked. Only use seat belts which have been approved by Mercedes-Benz. Do not make any modifications to the seat belts. This can lead to unintended activation of the ETDs or to their failure to activate when necessary. Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center. 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 Z Safety In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts. 49 Safety 50 Occupant safety 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. RWhen using a seat belt to secure infant restraints, toddler restraints, or children in booster seats, always follow the child seat manufacturer's instructions. G WARNING Do not pass seat belts over sharp edges. They could tear. Do not allow the seat belt to get caught in the door or in the seat adjustment mechanism. This could damage the seat belt. Never attempt to make modifications to seat belts. This could impair the effectiveness of the seat belts. Fastening seat belts 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. For additional information, see the "Children in the vehicle" section. A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint.

Damaged seat belts can no longer fulfill their protective function and must be replaced. Consult an authorized MercedesBenz Center. Belt warning for the driver and front passenger Regardless of whether the driver and front passenger have fastened their seat belts already, the 7 seat belt warning lamp lights up for 6 seconds after every engine start. It then goes out if the driver and the front passenger have fastened their seat belts. If the driver's seat belt is not fastened after the engine is started, an additional warning tone will sound. The warning tone goes out after approximately six seconds or once the driver's seat belt is fastened. If the driver or front passenger have not fastened their seat belt after 6 seconds and the doors are closed, the 7 seat belt warning lamp lights up. Runtil the driver or the front passenger have fastened their seat belts Rif a vehicle speed of 15 mph (25 km/h) is exceeded once, a warning tone with increasing intensity sounds additionally for a maximum of 60 seconds or until the driver or front passenger have fastened their seat belts. If the driver or front passenger undo their seat belts during the journey, the 7 seat belt warning lamp lights up and the warning tone sounds again. Z Safety X 51 Safety 52 Occupant safety The warning tone ceases even if the driver or front passenger have still not fastened their seat belt after 60 seconds. The 7 seat belt warning lamp stops flashing but continues to be lit. Once the vehicle is stationary, the warning tone is reactivated and the 7 seat belt warning lamp starts to flash again if the vehicle speed exceeds 15 mph (25 km/h) once. The 7 seat belt warning lamp only goes out if: Rboth the driver and the front passenger have fastened their seat belts. or Rthe vehicle is stationary and a door is open. i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belt" (Y page 239). Emergency Tensioning Devices, belt force limiters The front seat belts and the outer seat belts in the rear are equipped with ETDs and seat belt force limiters. The ETDs tighten the seat belts in an accident, pulling them close against the body. The ETDs do not correct incorrect seat positions or incorrectly fastened seat belts. The ETDs do not pull vehicle occupants back towards the backrest. Seat belt force limiters, when triggered, help to reduce the peak force exerted by the seat belt on the vehicle occupant. The seat belt force limiters for the front seats are synchronized with the front air bags. These take on a part of the deceleration force. Thus, the force exerted on the occupant is distributed over a greater area. The ETDs can only be activated when: Rthe ignition is switched on. restraint systems are operational; see "SRS warning lamp" (Y page 36). Rthe Rthe belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front. front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side. The ETDs on the outside seats in the rear compartment are triggered independently of the lock status of the seat belts. The ETDs are triggered depending on the type and severity of an accident: Rthe Rif, in 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 Rif, in the event of a side impact, on the side opposite the impact the vehicle decelerates or accelerates rapidly in a lateral direction If the air bags 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. The 6 SRS warning lamp lights up. G WARNING Pyrotechnic ETDs that were activated must be replaced. For your safety, when disposing of the pyrotechnic ETDs always follow our safety instructions. These are available at any authorized Mercedes-Benz Center. ! If the front-passenger seat is not occupied, do not engage the seat belt tongue in the buckle on the frontpassenger seat. Otherwise, the Emergency Tensioning Device could be triggered in the event of an accident. Children in the vehicle Child restraint systems Important safety notes We recommend that all infants and children be properly secured in an infant or child restraint system at all times while the vehicle is in motion. The use of seat belts and infant and child restraint systems is required by law in all 50 states, the District of Columbia, the U.S. territories and all 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. The infant or child restraint system must be properly secured in accordance with the manufacturer's instructions. All infant or child restraint systems must meet U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. An information label on the child restraint system indicates whether it meets these standards. This information is also provided in the installation instructions supplied with the child restraint system. 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 According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. 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 front passenger 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. RFor children larger than the typical 12-month-old child, the front passenger front air bag may or may not be activated. Always make sure the 4 5 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. 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 completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in a backseat. RIf you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 4 5 indicator lamp is illuminated, indicating that the front Z 53 Safety Children in the vehicle Safety 54 Children in the vehicle passenger front air bag is deactivated. Should the 4 5 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 4 5 indicator lamp while driving to make sure the 4 5 indicator lamp is illuminated. If the 4 5 indicator lamp goes out or remains out, do not transport a child on the front passenger seat until the system has been repaired. A 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. RIf you have to place a child in a forwardfacing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommended for the age, size and weight of the child, and secure child restraint with the vehicle's seat belt according to the child seat manufacturer's instructions. G WARNING Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt. A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint. Children too big for a toddler restraint must ride in seats using regular seat belts. Position the shoulder belt across the chest and shoulder, not face or neck. A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a booster. When the child restraint is not in use, remove it from the vehicle or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident. If an infant or child is traveling in the vehicle: X Secure the infant or child with an appropriate infant or child restraint recommended for the child's age and weight. X Make sure that the infant or child is properly secured at all times while the vehicle is in motion. G WARNING When leaving the vehicle, always remove the SmartKey from the ignition lock. Always take the SmartKey with you and lock the vehicle. Do not leave children unattended in the vehicle, even if they are secured in a child restraint system, or with access to an unlocked vehicle. A child's unsupervised access to a vehicle could result in an accident and/or serious personal injury. The children could: Rinjure themselves on parts of the vehicle seriously or fatally injured through excessive exposure to extreme heat or cold Rinjure themselves or cause an accident with vehicle equipment that can be operated even if the SmartKey is removed from the ignition lock or removed from the vehicle, such as seat adjustment, steering wheel adjustment, or the memory function If children open a door, they could injure other persons or get out of the vehicle and injure themselves or be injured by following traffic. Do not expose the child restraint system to direct sunlight. The child restraint system's metal parts, for example, could become very hot, and the child could be burned on these parts.

Driving safety systems Driving safety systems overview In this section, you will find information about the following driving safety systems: RABS (Anti-lock Braking System) RBAS (Brake Assist System) RBAS PLUS (Brake Assist System Plus*) RESP® (Electronic Stability Program) REBD (Electronic Brake force Distribution) RADAPTIVE BRAKE RPRE-SAFE® Brake Important safety notes If you fail to adapt your driving style, the driving safety systems can neither reduce the risk of accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road/weather conditions, as well as the traffic conditions and maintain a safe distance to the vehicle in front. Drive carefully. i Please note that the driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Pay particular attention to the information regarding tires, recommended minimum tire tread depths etc. in the "Wheels and tires" section (Y page 310). 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) may come on as well as messages in the multifunction display that may appear. If the ABS malfunctions, the wheels may lock during hard braking, reducing the steering capability and extending the braking distance. The ! warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running. Braking If ABS intervenes when braking, you will feel a pulsing in the brake pedal. X If ABS intervenes: continue to depress the brake pedal with force until the braking situation is over. X To make a full brake application: depress the brake pedal with full force. The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving. G WARNING Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pumping the brake pedal defeats the purpose of the ABS and significantly reduces braking effectiveness. Important safety notes i Observe the "Important safety notes" section (Y page 59). 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. ABS works from a speed of about 5 mph (8 km/h) upwards, regardless of road-surface conditions. ABS works on slippery surfaces, even when you only brake gently. G WARNING If the ABS malfunctions, other driving systems such as the BAS or the ESP® are also switched off. Observe indicator and warning lamps that BAS (Brake Assist System) i Observe the "Important safety notes" section (Y page 59). BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. 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. Z 59 Safety Driving safety systems 60 Driving safety systems Safety G WARNING If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase. BAS PLUS (Brake Assist System Plus) BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS. i Observe the "Important safety notes" section (Y page 59). At speeds above approximately 20 mph (30 km/h), BAS PLUS assists you when braking in hazardous situations and uses the radar sensor system to evaluate the traffic conditions. i 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. Removal, tampering, or altering of 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. Any unauthorized modification to this device could void the user's authority to operate the equipment. 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. At speeds up to approximately 40 mph (70 km/h), BAS PLUS can also detect stationary obstacles, for example stopped or parked vehicles. Should you approach an obstacle and BAS PLUS has detected a risk of collision, BAS PLUS calculates the braking force necessary to avoid a rear-end collision. Should you apply the brakes forcefully, BAS PLUS can automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: Ryou release the brake pedal. is no longer any danger of a rear-end collision. Rno obstacle is detected in front of your vehicle. BAS PLUS is then deactivated. For BAS PLUS to assist you when driving, the radar sensor system must be switched on and operational, see "Radar sensor system" in the index. Rthere G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. BAS PLUS cannot intervene in these cases. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else covering the sensors Rsnow or heavy rain Rinterference by other radar sources Rthe possibility of 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 G WARNING BAS PLUS does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rin curves As a result, BAS PLUS cannot intervene in critical situations. There is a risk of an Rto Driving safety systems 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. If BAS PLUS is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. ESP® (Electronic Stability Program) Important safety notes i See the "Important safety notes" section (Y page 59). 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. If necessary, 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. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. G WARNING Under no circumstances should you deactivate ESP® when the ÷ ESP® warning lamp in the instrument cluster flashes. Proceed as follows: Rwhen driving off, apply as little throttle as possible. Rwhile driving, ease up on the accelerator pedal. Radapt your speed to suit the prevailing road and weather conditions. Failure to observe these guidelines could cause the vehicle to skid. ESP® cannot prevent accidents resulting from excessive speed. ! Vehicles without 4MATIC: switch the ignition off when: Rthe parking brake is being tested using a dynamometer vehicle is being towed with the front axle raised Application of the brakes by ESP® may otherwise destroy the brake system. Rthe ! Vehicles with 4MATIC: switch off the ignition when the parking brake is being tested on a brake dynamometer. Application of the brakes by ESP® may otherwise destroy the brake system. ! Vehicles with 4MATIC: function or performance tests may only be carried out on a 2-axle dynamometer.

PRE-SAFE® Brake can help you to minimize the risk of a frontal collision with a vehicle ahead or reduce the effects of such a collision. If PRE-SAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. PRE-SAFE® Brake cannot prevent a collision without your intervention. At speeds above approximately 20 mph (30 km/h), this function warns you when you are rapidly approaching the vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp in the instrument cluster will light up. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action provided it is safe to do so. If the driver and front passenger have their seat belt fastened, PRE-SAFE® Brake can also brake the vehicle automatically at speeds from approximately 20 mph (30 km/h) to approximately 124 mph (200 km/h). Due to the nature of the system, particularly complicated driving conditions may cause unnecessary warnings or the unnecessary intervention of PRE-SAFE® Brake. To stop the braking action, you can either depress the accelerator pedal further, activate kickdown or release the brake pedal. The braking action of PRE-SAFE® Brake is ended automatically if: Ryour speed drops below approximately 9 mph (15 km/h). Ryou maneuver to avoid the obstacle.

Seats Important safety notes G WARNING In order to avoid possible loss of vehicle control, all seat, head restraint, steering wheel and rear view mirror adjustments, as well as fastening of seat belts, must be done before setting the vehicle in motion. G WARNING Do not adjust the driver's seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle. Never travel in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. This could cause serious or fatal injuries. The seat backrest and seat belts provide the best restraint when the wearer is in a position that is as upright as possible and seat belts are properly positioned on the body. G WARNING Your seat belt must be adjusted so that you can correctly fasten your seat belt. Observe the following points: Radjust the seat backrest until your arms are slightly angled when holding the steering wheel. Radjust the seat to a comfortable seating position that still allows you to reach the accelerator/brake pedal safely. The position should be as far back as possible with the driver still able to operate the controls properly. Radjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. Rnever place hands under the seat or near any moving parts while a seat is being adjusted. Failure to do so could result in an accident and/or serious personal injury. G WARNING The electrically adjustable seats can be operated at any time. Therefore, do not leave children unattended in the vehicle, or with access to an unlocked vehicle. A child's unsupervised access to a vehicle could result in an accident and/or serious personal injury. G WARNING According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. 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 appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. For additional information, see "Children in the vehicle". A child's risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint. G WARNING For your protection, drive only with properly positioned head restraints. Adjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level.

Exterior lighting Important safety notes For reasons of safety, Mercedes-Benz recommends that you drive with the lights switched on even during the daytime. In some countries, operation of the headlamps varies due to legal requirements and self-imposed obligations. Information about driving abroad Converting to symmetrical low beam when driving abroad: switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road to the country where the vehicle is registered. This prevents glare to oncoming traffic. Symmetrical lights do not illuminate as large an area of the edge of the road. Have the headlamps converted at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center, as close to the border as possible before driving in these countries. Converting to asymmetrical low beam after returning: have the headlamps converted back to asymmetrical low beam at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center, as soon as possible after crossing the border again. 7 Illustration: light switch with the à symbol for the automatic headlamp mode/daytime running lamps 1W Left-hand standing lamps 2X Right-hand standing lamps 3T Parking lamps, license plate and instrument cluster lighting 4à Automatic headlamp mode/daytime running lamps 5L Low-beam/high-beam headlamps BR Rear fog lamp CN Front fog lamps7 Only vehicles with front fog lamps have the fog lamps function. Exterior lighting 107 Low-beam headlamps X To switch on the low-beam headlamps: turn the SmartKey in the ignition lock to position 2 or start the engine.

This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly. i The integrated filter can filter out most particles of dust and completely filters out pollen. 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 Service Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Service Booklet. i It is possible that the residual heat function may be activated automatically an hour after the SmartKey is removed. The vehicle is then ventilated for 30 minutes to dry the air-conditioning system. G WARNING Follow the recommended settings for heating and cooling given on the following pages. Otherwise, the windows could fog up, impairing visibility and endangering you and others.

The driver's concentration must always be directed primarily at road traffic. For your own safety and that of others, we recommend that you stop the vehicle at a safe place and in accordance with the traffic conditions before making or accepting a phone call. Comply with all legal requirements if you use the telephone while driving. Use the handsfree system and only use the telephone when road, weather and traffic conditions permit. In some jurisdictions, it is forbidden for drivers to use mobile phones while driving. Only operate the audio system or COMAND (Cockpit Management and Data System) in compliance with all legal requirements and when the road, weather and traffic conditions permit. You may otherwise not be able to observe the traffic conditions, endangering yourself and others. Remember that your vehicle covers a distance of 44 feet (approximately 14 m) a second when it is traveling at only 30 mph (approximately 50 km/h). Drive sensibly – save fuel Observe the following tips to save fuel: X The tires should always be inflated to the recommended tire pressure. X Remove unnecessary loads. X Remove roof racks when they are not needed. X Warm up the engine at low engine speeds. X Avoid frequent acceleration or braking. X Have all maintenance work carried out as indicated by the service intervals in the Service Booklet or by the service interval display. Fuel consumption also increases when driving in cold weather, in stop-and-go traffic and in mountainous 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 are 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. Pedals G WARNING Make sure absolutely no objects are obstructing the pedals' range of movement. Keep the driver's footwell clear of all obstacles. If there are any floormats or carpets in the footwell, make sure that the pedals still have sufficient clearance. During sudden driving or braking maneuvers, the objects could get caught between the pedals. You could then no longer brake or accelerate. This could lead to accidents and injury. Rolling with the engine switched off G WARNING There is no power assistance for the steering and the brake when the engine is not running. Steering and braking requires significantly more effort and you could lose control of the vehicle and cause an accident as a result. Do not turn off the engine while the vehicle is in motion. Z Driving and parking Driving tips 155 156 Driving tips Exhaust check Driving and parking G WARNING Inhalation of exhaust gas is hazardous to your health. All exhaust gas contains carbon monoxide (CO), and inhaling it can cause unconsciousness and possible death. Do not run the engine in confined areas (such as a garage) which are not properly ventilated. If you think that exhaust gas fumes are entering the vehicle while driving, have the cause determined and corrected immediately. If you must drive under these conditions, drive only with at least one window fully open at all times. 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 when they are maintained exactly in accordance with the manufacturer's specifications. For this reason, all work on the engine must be carried out only by qualified and authorized Mercedes-Benz technicians. The engine settings must not be changed in 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 Service Booklet. Brakes 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 Depressing the brake pedal constantly results in excessive and premature wear to the brake pads. It may also cause the brakes to overheat, seriously impairing their effectiveness. It may then not be possible to stop the vehicle in sufficient time to avoid an accident. If the brakes have been subjected to a heavy load, do not stop the vehicle immediately, but drive on for a short while. This allows the airflow to cool the brakes more quickly. Wet roads G WARNING G WARNING After driving in heavy rain for some time without applying the brakes or through water deep enough to wet brake components, the first braking action may be somewhat reduced. You have to depress the brake pedal more firmly. Maintain a safe distance from vehicles in front. G WARNING 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. Important safety notes On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control. Make sure that you do not endanger other road users when you apply the brakes. Driving tips G WARNING The layer of salt on the brake discs and the brake pads/linings may cause a delay in the braking effect, resulting in a significantly longer braking distance, which could lead to an accident. To avoid this danger, you should: Roccasionally brake carefully, without putting other road users at risk, when you are driving on salted roads. This helps to remove any salt that may have started to build up on the brake discs and the brake pads/linings. Rmaintain a greater distance to the vehicle ahead and drive with particular care. Rcarefully apply the brakes at the end of a trip and immediately after commencing a new trip, so that salt residues are removed from the brake discs. 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 an authorized Mercedes-Benz Center. All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. This work should be carried out at an authorized Mercedes-Benz Center. Have the brake pads replaced and the brake fluid renewed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. G WARNING If brake pads or brake fluid other than those recommended are used, the braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired. This could result in an accident. ! 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 your brake system is subject only to moderate loads, you should test the functionality of your brakes at regular intervals by pressing firmly on the brake pedal at high speeds. This improves the grip of the brake pads.

High-performance brake system for AMG vehicles The high-performance brake system is installed only on the C 63 AMG. G WARNING New vehicle brake pads and discs, and replacement brake pads and discs may take several hundred miles of driving until they provide optimum braking efficiency. Until that time, you may need to use increased brake pedal pressure while braking. Please be aware of this and adjust your driving and braking accordingly during this break-in period. Excessive high-demand braking will cause correspondingly high brake wear. Please be attentive to the brake warning lamp in the instrument cluster and brake condition messages in the multifunction display. Especially for high performance driving, it is important to maintain and have the brake system checked regularly. 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 of individual components of the brake system, such as the brake pads/linings or brake discs, depends on the individual driving style and 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. 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 can occur you must drive in the following manner: Rthe Rreduce 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 General notes G WARNING If the vehicle becomes trapped in snow, ensure that snow is kept away from the exhaust pipe and from around the vehicle as long as the engine is running. Otherwise, poisonous carbon monoxide (CO) may enter the vehicle, resulting in loss of consciousness and even death. Driving systems At the onset of winter, have your vehicle winterproofed at a qualified specialist workshop, e.g. at an authorized MercedesBenz Center. Observe the notes in the "Winter operation" section (Y page 312). Driving with summer tires Observe the notes in the "Winter operation" section (Y page 312). Slippery road surfaces G WARNING The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose. 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. G WARNING On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control. Drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking maneuvers. Do not use 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 313). G WARNING Driving systems Cruise control Important safety notes 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, which 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 set any road speed above 20 mph (30 km/h). G WARNING The cruise control is a convenience system designed to assist the driver during vehicle operation. The driver is and must always remain responsible for the vehicle's speed and for safe brake operation. Only use the cruise control if the road, traffic, and weather conditions make it advisable to travel at a constant speed. RThe use of the cruise control can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed. RThe use of the cruise control can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. RDeactivate the cruise control when driving in fog. The "Resume" function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed. Make sure that you do not endanger other road users when you apply the brakes. Z Driving and parking To assure sufficient fresh air ventilation, open a window slightly on the side of the vehicle not facing the wind. 159 160 Driving systems G WARNING Driving and parking The cruise control brakes automatically so that the set speed is not exceeded.

DISTRONIC PLUS Important safety notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. 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, which relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly. If a slower-moving vehicle is detected in front, DISTRONIC PLUS causes your vehicle to brake and maintain the preset distance to the vehicle in front. G WARNING The DISTRONIC PLUS requires familiarity with its operational characteristics. We strongly recommend that you review the following information carefully before operating the system. G WARNING The DISTRONIC PLUS is a convenience system. Its speed adjustment reduction capability is intended to make cruise control more effective and usable when traffic speeds vary. It is not however, intended to, nor does it, replace the need for extreme care. The responsibility for the vehicle's speed, distance to the preceding vehicle and, most importantly, brake operation to ensure a safe stopping distance, always remains with the driver. The DISTRONIC PLUS cannot take street and traffic conditions into account. Complex driving situations are not always fully recognized by the DISTRONIC PLUS. This could result in wrong or missing distance warnings. Z Driving and parking overtake, cruise control adjusts the vehicle's speed to the last speed stored after you have finished overtaking. 161 Driving and parking 162 Driving systems If you want DISTRONIC PLUS to assist you, the radar sensor system must be activated (Y page 208) and operational. If there is no vehicle driving in front of you, DISTRONIC PLUS functions like cruise control at a 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 functions at a 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. You can refer to the applicable section in the Operator's Manual if there are any questions concerning this. i USA only: This device has been approved by the FCC as a “Vehicular Radar System”.

Any unauthorized modification to this device could void the user’s authority to operate the equipment. G WARNING The DISTRONIC PLUS adaptive cruise control is not a substitute for active driving involvement. It does not react to pedestrians or on stationary objects, nor does it recognize or predict the curvature and lane layout or the movement of preceding vehicles. The DISTRONIC PLUS can only apply a maximum of 40% of the vehicle's braking power. The DISTRONIC PLUS may not detect narrow vehicles possibly driving in front of you, such as motorcycles and vehicles driving in an offset formation. It is the driver's responsibility at all times to be attentive to the road, weather and traffic conditions. Additionally, the driver must provide the steering, braking and other driving inputs necessary to remain in control of the vehicle. High-frequency sources such as toll stations, speed measuring systems etc. can cause the DISTRONIC PLUS system to temporarily cease functioning. G WARNING The DISTRONIC PLUS cannot take road and traffic conditions into account. Only use the DISTRONIC PLUS if the road, weather and traffic conditions make it advisable to travel at a constant speed. G WARNING Use of the DISTRONIC PLUS can be dangerous on slippery roads. Rapid changes in tire traction can result in wheel spin and loss of control. The DISTRONIC PLUS does not function in adverse sight and distance conditions. Do not use the DISTRONIC PLUS during conditions of fog, heavy rain, snow or sleet. Driving systems The DISTRONIC PLUS cannot take weather conditions into account. Switch off the DISTRONIC PLUS or do not switch it on if: Rroads are slippery or covered with snow or ice. The wheels could lose traction while braking or accelerating, and the vehicle could skid. Rthe DISTRONIC PLUS system sensor covers are dirty or visibility is diminished due to snow, rain or fog, for example. The distance control system functionality could be impaired. Always pay attention to surrounding traffic conditions even while the DISTRONIC PLUS is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late. This could cause an accident in which you and/or others could be injured. G WARNING The "Resume" function should only be operated if the driver is fully aware of the previously set speed and wishes to resume this particular preset speed. G WARNING Your undivided attention to street and traffic conditions is necessary at all times whether DISTRONIC PLUS is active or not. The use of DISTRONIC PLUS can be dangerous on winding roads or in heavy traffic because conditions do not allow safe driving at a constant speed. DISTRONIC PLUS does not react to stationary objects on the road (for example, a vehicle stopped in traffic or an abandoned vehicle). DISTRONIC PLUS likewise does not react to oncoming vehicles. Deactivate DISTRONIC PLUS: Rwhen changing to the right lane, if the vehicles in the left lane are driving slower Rwhen driving into a filter lane or an expressway exit Rin complex driving situations, for example in construction sites on an expressway In these situations DISTRONIC PLUS will maintain the set speed if it is not deactivated. DISTRONIC PLUS is intended only for maintaining a set speed and a set distance from the objects moving in front of the vehicle. G WARNING An intermittent warning sounds and the distance warning lamp · in the instrument cluster is illuminated if the DISTRONIC PLUS system calculates that the distance to the vehicle ahead and your vehicle's current speed indicate that the DISTRONIC PLUS will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision. Immediately brake the vehicle to increase your distance to the preceding vehicle. The warning sound is intended as a final caution in which you should intercede with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking. This will result in potentially dangerous emergency braking which will not always result in an impact being avoided. Tailgating increases the risk of an accident. G WARNING DISTRONIC PLUS brakes your vehicle with a maximum deceleration of 13 ft/s2(4 m/s2). This is equivalent to approximately 40 % of your vehicle's maximum possible deceleration. Z Driving and parking G WARNING 163 164 Driving systems Driving and parking You need to brake yourself to prevent a collision. DISTRONIC PLUS brakes the vehicle to restore the set distance from the vehicle ahead or the set speed. G WARNING If you do not receive visual or acoustic warning signals during a critical traffic situation, DISTRONIC PLUS has either not recognized the collision risk, has been deactivated or is malfunctioning. Remember, whether or not DISTRONIC PLUS is operating, it is ultimately always the drivers responsibility to apply the brakes in order to control the vehicle and avoid a collision.

The set distance to a slowermoving vehicle in front will then not be maintained. You will be driving at the speed Driving systems Activating when driving towards a stationary vehicle If the vehicle in front of you is stationary, you can only activate DISTRONIC PLUS once your vehicle is stationary as well. X Briefly pull the cruise control lever towards you ?, or briefly press up : or down ;. DISTRONIC PLUS is selected. i DISTRONIC PLUS can only be activated at under 20 mph (30 km/h) if a vehicle in front has been detected. Therefore, the DISTRONIC PLUS distance display in the instrument cluster should be activated (Y page 204). X Keep the cruise control lever pressed up : or down ; until the desired speed is set. i You can use the cruise control lever to set the stored speed and the control on the cruise control lever to set the specified minimum distance (Y page 168). Pulling away X If the vehicle in front pulls away: remove your foot from the brake pedal. X Briefly pull the cruise control lever towards you ?. or X Accelerate briefly. 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 a slower-moving vehicle is detected in front, DISTRONIC causes your vehicle to brake. This maintains the preset distance to the vehicle in front. If DISTRONIC PLUS detects a faster-moving vehicle in front, it increases the driving speed of your vehicle, but only up to the desired speed you have stored. G WARNING If you depress the brake, DISTRONIC PLUS is deactivated unless your vehicle is stationary. DISTRONIC PLUS then no longer brakes your vehicle. In such cases, control the distance from vehicles travelling in front with the brake alone. You could otherwise cause an accident and thereby injure yourself and others. The driver remains fully responsible for the vehicle's distance from other vehicles, the speed being driven and for braking in good time. Changing lanes If you wish to change to the passing lane (in left-hand-drive vehicles, the passing lane is the left-hand lane), DISTRONIC PLUS supports you if: 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 signals. RDISTRONIC PLUS does not detect a danger of collision. If these conditions are met, 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. G WARNING DISTRONIC PLUS and Active Blind Spot Assist are only aids designed to assist driving. They do not relieve you of the responsibility of paying attention. The driver remains fully responsible for the vehicle's distance from other vehicles, the vehicle's speed and for braking in good time. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. Z Driving and parking you determine by the position of the accelerator pedal. 165 166 Driving systems Driving and parking Vehicles with COMAND i The following function is not operational in all countries. DISTRONIC PLUS uses additional information from your navigation system so that it can react appropriately to certain traffic situations. This is the case if, while following a vehicle, DISTRONIC PLUS is active and you: DISTRONIC PLUS must also never be operated, activated or deactivated by a passenger or from outside the vehicle. DISTRONIC PLUS does not replace the parking brake and must not be used for parking. The DISTRONIC PLUS braking effect is canceled and the vehicle can start moving if: Rapproach RDISTRONIC or drive through a traffic circle a T intersection Rturn off at a freeway exit Even if the vehicle in front leaves the detection range, DISTRONIC PLUS temporarily maintains the current driving speed and does not accelerate. This is based on the current map data in the navigation system. Rapproach Example: traffic circle The current speed is maintained: Rapproximately 10 seconds before the traffic circle/T intersection and for approximately 1.5 seconds when driving on the traffic circle Rapproximately 12 seconds before reaching a freeway exit and approximately 4 seconds after the freeway exit Afterwards, the vehicle accelerates back to the set speed you specified.

This means that: RYour vehicle can pass another vehicle after you have changed lanes. in a sharp turn or if the preceding vehicle is in a sharp turn, the DISTRONIC RWhile The ability of DISTRONIC PLUS to detect vehicles when cornering is limited. Your vehicle may brake unexpectedly or late. Vehicles traveling on a different line Driving systems DISTRONIC PLUS may not detect vehicles traveling on a different line. The distance to the vehicle in front will be too short. 171 Obstructions and stationary vehicles DISTRONIC PLUS has not detected the vehicle cutting in yet. The distance to this vehicle will be too short. DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the detected vehicle turns a corner and reveals an obstacle or stationary vehicle, DISTRONIC PLUS will not brake for these. Crossing vehicles Narrow vehicles DISTRONIC PLUS has not yet detected the vehicle in front on the edge of the road, because of its narrow width. The distance to the vehicle in front will be too short. DISTRONIC PLUS may mistakenly detect vehicles that are crossing your lane. Activating DISTRONIC PLUS at traffic lights with crossing traffic, for example, could cause your vehicle to pull away unintentionally.

ATTENTION ASSIST Important safety notes ATTENTION ASSIST helps you during long, monotonous journeys such as on freeways and interstate 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. G WARNING ATTENTION ASSIST is only an aid and may detect your tiredness or lapses in concentration too late or not at all. It is not a substitute for a well-rested and attentive driver. Fatigue may cause you to recognize hazardous situations too late, misjudge a situation or react more slowly. For this reason, make sure you feel rested before you begin driving and during your journey. Make sure that you take regular breaks in time, particularly on long journeys. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. 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 Rdriving conditions, e.g. time, driving time 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 predominantly drive at speeds under 50 mph (80 km/h) or over 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 205).

Ryou Lane Tracking package General notes The Lane Tracking package consists of Blind Spot Assist (Y page 183) and Lane Keeping Assist (Y page 185). Blind Spot Assist Important safety notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from speeds 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 lane, you will also receive an optical and audible collision warning. Blind Spot Assist uses sensors in the rear bumper for monitoring purposes. G WARNING Blind Spot Assist is only an aid designed to assist driving. It may fail to detect some vehicles and is no substitute for attentive driving. Blind Spot Assist cannot detect road and traffic conditions. It may fail to detect narrow vehicles, such as motorcycles or bicycles, or may only detect them too late. Monitoring may be affected by dirty sensors, strong spray or poor visibility caused by snow, Z 183 Driving and parking Driving systems Driving and parking 184 Driving systems rain or mist, for example. In this case, vehicles are detected late or not at all. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. 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. Removal, tampering, or altering of 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. Any unauthorized modification to this device could void the user’s authority to operate the equipment. For Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 208) and operational. Monitoring range of the sensors Blind Spot Assist monitors the area shown in the figure up to 10 ft (3 m) behind and immediately adjacent to your vehicle. G WARNING Blind Spot Assist monitors certain areas in the immediate vicinity of your vehicle. Vehicles that approach and drive past at high speeds are not detected. There is no display and no warning. If the lanes are very wide, it may not be possible to monitor the complete width of the neighboring lane. For this reason, vehicles in the next lane may not be detected, especially if they are driving in a staggered formation. This may be the case if vehicles are driving at that edge of their lane which is furthest away from your vehicle. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. 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 the vehicles are driving on the inner side of their lane. Due to the nature of the system: Rwarnings may be issued in error when driving close to crash barriers or similar solid lane borders. Rwarnings may be interrupted when driving alongside long vehicles, such as trucks, for a prolonged time. The two sensors for Blind Spot Assist are integrated into the sides of the rear bumper. Make sure that the bumper is free from dirt, ice or slush around the sensors. The rear sensors must not be covered, for example by bicycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. Blind Spot Assist may otherwise not work properly. Indicator and warning display : Yellow indicator lamp/red warning lamp When Blind Spot Assist is activated, indicator lamp : lights up yellow in the exterior mirrors up to a vehicle speed of 20 mph (30 km/h). When the vehicle speed exceeds 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is ready for use. When your speed exceeds approximately 20 mph (30 km/h), warning lamp : lights up red on the corresponding side whenever a vehicle is detected in the blind spot monitoring range. This warning is always given when a vehicle enters the blind spot monitoring range from behind or from the side. When you are passing another vehicle, the warning is emitted only 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 turn signal, a double warning tone sounds. Red warning lamp : flashes.

When the vehicle speed exceeds 20 mph (30 km/h), the indicator lamp goes out and Active Blind Spot Assist is ready for use. When your speed exceeds approximately 20 mph (30 km/h), warning lamp : lights up red on the corresponding side whenever a vehicle is detected in the blind spot monitoring range. This warning is always given when a vehicle enters the blind spot monitoring range from behind or from the side. When you are passing another vehicle, the warning is emitted only 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. G WARNING Active Blind Spot Assist is not active at speeds lower than 20 mph (30 km/h). The indicator lamps in the exterior mirrors are yellow. Vehicles in the monitoring range are then not indicated. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. Visual and audible collision warnings If you switch on the appropriate turn signals and a vehicle is detected in the side monitoring range, you will receive a visual and acoustic collision warning. You will hear a double warning tone and 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. Course-correcting brake application If Active Blind Spot Assist detects a risk of a lateral collision in the monitoring range, a course-correcting brake application is carried out. This is meant to assist you in avoiding a collision. The course-correcting brake application is available in the 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: G WARNING Active Blind Spot Assist is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the course-correcting brake application is not sufficient to avoid a collision. In such a case, you must steer, brake or accelerate. In very rare cases, the system may erroneously detect a danger of collision in the area of crash barriers or similar lane borders and apply the brakes. Active Blind Spot Assist does not detect all traffic situations and road users. Always make sure that there is sufficient distance on the side for other traffic or obstacles. An inappropriate brake application may be interrupted at any time if you steer slightly in the opposite direction or accelerate. You are responsible for driving at appropriate speeds, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. There will be either no or only a weak coursecorrecting brake application if: Rthere are vehicles or obstacles, e.g. crash barriers, located on both sides of your vehicle.

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 have selected the Display Unit Speed-/Odometer(Y page 206) function in the on-board computer and select km as the unit of measurement, Active Lane Keeping Assist is active from speeds of 60 km/h. If the miles display unit is selected, the assistance range begins at 40 mph. G WARNING Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid and may detect the lane markings on the road incorrectly or not at all. The system may be impaired or may not function if: Rseveral or no lane markings for a single lane are present. 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 reflection from other vehicles. Rthere Rthe windshield is dirty, fogged up or covered, for instance by a sticker, in the vicinity of the camera. 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 on the road are unclear, e.g. near roadworks. Rthe lane markings change quickly, e.g. lanes branch off, cross one another or merge. Rthe road is narrow and winding. Active Lane Keeping Assist cannot detect road and traffic conditions. It is not a substitute for attentive driving. You are responsible for the vehicle's speed, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others. Warning vibration in the steering wheel A warning can be given when a front wheel passes over a lane marking. You will be warned by means of intermittent vibration in the steering wheel for up to 1.5 seconds. In order that you are warned only when necessary and in good time if you cross the lane marking, the system recognizes certain conditions and warns you accordingly. The warning vibration occurs earlier if: Ryou approach the outer lane marking on a bend. Rthe road has very wide lanes, e.g. a freeway. Rthe system recognizes solid lane markings. The warning vibration occurs later if: Rthe Ryou road has narrow lanes. cut the corner on a bend. No warning vibration occurs if: Ryou clearly and actively steer, brake or accelerate. Ryou cut the corner on a sharp bend. Ra driving safety system intervenes, e.g. ABS, BAS or ESP®. Ryou switch on the turn signals. In this event, the warnings are suppressed for a certain period of time. Lane-correcting brake application If you leave your lane under certain circumstances the vehicle will brake briefly on one side. This is meant to assist you in bringing the vehicle back to the original lane. This function is available in the range between 40 mph and 120 mph (60 km/h to 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. In addition, a lane with lane markings on both sides must be recognized. The brake application also slightly reduces vehicle speed. If a lane-correcting brake application occurs, the following, for example, appears in the multifunction display: i A further lane-correcting brake application can only occur after your vehicle has returned to the original lane. G WARNING Active Lane Keeping Assist does not keep your vehicle in its lane. It is only an aid designed to assist driving. It is not a substitute for attentive driving. In some cases, the lane- correcting brake application is not sufficient to bring your vehicle back to the original lane. In such cases, you must steer the vehicle yourself to ensure that it does not leave the lane. Active Lane Keeping Assist does not detect road and traffic conditions. Always make sure that there is sufficient distance to the side for other traffic or obstacles. In rare cases, unclear markings or particular structures on the roadway can be recognized as solid lane markings. An inappropriate brake application, e.g. after intentionally driving over a solid lane marking, may be interrupted at any time by steering slightly in the opposite direction. Active Lane Keeping Assist cannot take weather conditions into account. You are responsible for the driving at appropriate speeds, braking in good time, and steering correctly. Always adapt your driving style to suit the prevailing road and weather conditions. Always pay attention to traffic conditions and your surroundings. Otherwise, you may fail to recognize dangers in time, cause an accident and injure yourself and others.

You may lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up and possibly a fire. G WARNING Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Z 233 On-board computer and displays Display messages 234 Display messages On-board computer and displays Display messages Check Tire Pressure Soon Possible causes/consequences and M Solutions G Risk of accident The tire pressure loss warning system has detected a significant loss in pressure.

G WARNING Each tire, including the spare (if provided), should be checked at least every two weeks when cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire and Loading Information placard on the driver's door B-pillar or, if available, 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 pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. USA only: Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately 1 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.

Also, the operating clearance of the wheels and the tires may no longer be correct. G WARNING Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them. When replacing rims, only use genuine Mercedes-Benz wheel bolts specified for the particular rim type. Failure to do so can result in the bolts loosening and possibly an accident. Retreaded tires are not tested or recommended by Mercedes-Benz, since previous damage cannot always be recognized on retreads. The operating safety of the vehicle cannot be assured when such tires are used. G WARNING If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage to your vehicle has occurred, you should turn on the hazard warning flashers, carefully slow down, and drive with caution to an area which is a safe distance from the road. Inspect the tires and the vehicle underbody for possible damage. If the vehicle appears unsafe, have the vehicle towed to the nearest authorized Mercedes-Benz Center or tire dealer for repairs. G WARNING Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You might lose control of the vehicle. Continued driving with a flat tire or driving at high speed with a flat tire will cause excessive heat buildup and possibly a fire. i Further information about Tires and wheels can be obtained from any authorized Mercedes-Benz Center. Operation Notes on driving RIf the vehicle is heavily laden, check the tire pressures and correct them if necessary. 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, can get damaged. RWhen Operation G WARNING Regularly check the tires for damage. Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. Worn, old tires can cause accidents. If the tire tread is worn to minimum tread depth, or if the tires have sustained damage, replace them. RRegularly check the wheels and tires of your vehicle for damage (e.g. cuts, punctures, tears, bulges on tires and deformation or cracks or severe corrosion on wheels) 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. RRegularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 311). 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 (such as tire pressure monitoring systems) other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. 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 313). Tire tread G WARNING Although the applicable federal motor vehicle safety laws consider a tire to be worn when the tread wear indicators (TWI) become visible at approximately 1/16 in (1.6 mm), we recommend that you do not allow your tires to wear down to that level. As tread depth approaches 1/8 in (3 mm), the adhesion properties on a wet road are sharply reduced. Depending upon the weather and/or road surface (conditions), the tire traction varies widely. Do not use tires that are excessively worn as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 inch (3 mm). Tread wear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They become visible as soon as a tread depth of approximately 1/16 inch (1.6 mm) has been reached. If this is the case, the tire is so worn that it must be replaced. The recommended tread depth for summer tires is at least 1/8 inch (3 mm). The recommended tread depth for winter tires is at least 1/6 inch (4 mm). Bar marking : for tread wear is integrated into the tire tread. Notes on selecting, mounting and replacing tires ROnly mount tires and wheels of the same type and make. ROnly mount tires of the correct size onto the wheels. RAfter mounting new tires, run them in at moderate speeds for the first 60 miles Z Wheels and tires Notes on regularly inspecting wheels and tires 311 312 Winter operation (100 km) as they only reach their full performance after this distance. RDo not use tires that are excessively worn as the tire traction on wet road surfaces decreases significantly when the tread depth is less than 1/8 inch (3 mm). RReplace the tires after six years at the latest, regardless of wear. This also applies to the spare wheel/emergency spare wheel. The service life of tires depends on the following factors amongst other things: style Rtire pressure Rmileage Wheels and tires Rdriving MOExtended tires (tires with run-flat properties) MOExtended tires (tires with run-flat properties) allow you to continue driving your vehicle even if one or more tires are entirely deflated. MOExtended tires may be used only in conjunction with the activated tire pressure loss warning system or the activated tire pressure monitoring system and only on wheels specifically tested by Mercedes-Benz. You will find notes on driving with MOExtended tires in the "Breakdown assistance" section (Y page 297). Winter operation Please bear the following in mind At the onset of winter, have your vehicle winterproofed at a qualified specialist workshop, e.g. at an authorized MercedesBenz Center. Observe the notes in the "Changing a wheel" section (Y page 334). Driving with summer tires At temperatures below 45 ‡ (+7 †), the elasticity of summer tires and therefore also traction and braking capability are reduced considerably — equip your vehicle with M+S tires. Using summer tires at very cold temperatures could cause tears to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage. M+S tires 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. G WARNING M+S tires with a tread depth of less than 1/ inch (4 mm) must be replaced 6 immediately. They are no longer suitable for use in winter. Always observe the maximum permissible speed specified for the M+S tires you have mounted. When you have mounted M+S tires: X Check the tire pressures (Y page 317). Vehicles for Canada: restart the tire pressure loss warning system (Y page 317). X Vehicles for USA: restart the tire pressure monitor (Y page 319). X Tire pressure If you use your spare wheel when M+S tires are mounted on the other wheels, be aware that the difference in tire characteristics impairs cornering ability and reduces driving stability. Adapt your driving style accordingly. Have the spare wheel replaced by a normal wheel with an M+S tire at the nearest Mercedes-Benz Center. Snow chains For safety reasons, Mercedes-Benz recommends that you only use snow chains which have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding standard of quality. ! There is not enough space for snow chains on some wheel sizes. Observe the information under "Tires and wheels" in the "Technical Data" section to avoid damage to the vehicle or the wheels. ROnly use snow chains when driving on roads completely covered by snow. Do not exceed the maximum permissible speed of 30 mph (50 km/h). Remove the snow chains as soon as possible when you are no longer driving on snow-covered roads. RLocal regulations may restrict the use of snow chains. Applicable regulations must be observed if you wish to mount snow chains. RSnow chains must not be mounted on emergency spare wheels. If you intend to mount snow chains, please bear the following points in mind: Ryou may not attach snow chains to all wheel-tire combinations; see the information under "Wheel and tire combinations" in the "Wheels and tires" section. Rmount snow chains only in pairs and only to the rear wheels. Observe the manufacturer's installation instructions. ! If snow chains are mounted on the front wheels, the snow chains could grind against the bodywork or components of the chassis. This could result in damage to the vehicle or the tires. ! 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. i You may wish to deactivate ESP®(Y page 61) when pulling away with snow chains mounted. This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). Tire pressure Tire pressure specifications G WARNING Follow recommended tire inflation pressures. Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. The recommended tire pressures for the tires mounted at the factory can be found on the labels described here.

The actual number of seats may differ. : 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. 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 328). Tire pressure 315 Important notes on tire pressure G WARNING Should the tire pressure drop repeatedly: Rcheck the tire for foreign bodies. Rcheck whether the wheel is losing air or the valve is leaking. sure that only a valve cap approved by Mercedes-Benz is used on the tire valve. Tire pressures that are too low have a negative effect on vehicle safety, which could lead you to cause an accident. 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: Option 3) The tire pressure for the emergency/collapsible spare wheel (depending on vehicle equipment) can be found: To test tire pressure, use a suitable tire pressure gauge. The outer appearance of a tire does not permit any reliable conclusion 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.

For further information, consult a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has not been driven more 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.

Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are more likely to become punctured or damaged by road debris, potholes etc. Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. Check the tire pressure at least once a month. Only check and correct tire pressures when the tires are cold (Y page 313). Checking tire pressure manually To determine and set the correct tire pressure, proceed as follows: X 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 If necessary, increase the tire pressure to the recommended value (Y page 313). 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. Tire pressure loss warning system (Canada only) Important safety 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. G WARNING If the Check Tire Pressure Soon message appears in the multifunction display, one or more tires are significantly underinflated. Stop the vehicle as soon as possible and inflate the tires to the pressure specified on the vehicle's Tire and Loading Information placard or (where available) in the tire pressure table. 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. Check all tires when cold, including the spare tire, at least once a month. The tires should be inflated to the recommended pressure. This information can be found: Ron the Tire and Loading Information placard on the B-pillar on the driver's side or Rin the table for the tire pressure on the inside of the fuel filler flap Z Wheels and tires Checking the tire pressures 317 318 Tire pressure Wheels and tires G WARNING The tire pressure loss warning system does not provide a warning for wrongly selected tire inflation pressures. Always adjust tire inflation pressure according to the Tire and Loading Information placard on the driver's door B-pillar or on the tire inflation pressure label located on the inside of the fuel filler flap. The tire pressure loss warning system does not replace regular checks of the tire inflation pressures since a gradual pressure loss in more than one tire cannot be detected by the tire pressure loss warning system. The tire pressure loss warning system is not able to issue a warning due to a sudden dramatic loss of tire inflation pressure (e.g. tire blowout caused by a foreign object). In this case bring the vehicle to a halt by carefully applying the brakes and avoiding abrupt steering maneuvers. The function of the tire pressure loss warning system is limited or delayed if: Rsnow chains are mounted to your vehicle's tires. Rroad conditions are wintry. Ryou are driving on sand or gravel. Ryou adopt a very sporty driving style (cornering at high speeds or driving with high rates of acceleration). Ryou are driving with a heavy load (in the vehicle or on the roof). Restarting the tire pressure loss warning system Restart the tire pressure loss warning system if you have: Rchanged the tire pressure Rchanged the wheels or tires Rmount new wheels or tires X Before restarting, consult the Tire and Loading Information placard on the B-pillar on the driver's side or the tire pressure table on the inside of the fuel filler flap to ensure the tire pressure in all four tires is set correctly for the current operating conditions. X Observe the notes in the section on tire pressures (Y page 313). G WARNING The tire pressure loss warning system can only give reliable warnings if you have set the correct tire pressure. If an incorrect tire pressure is set, these incorrect values will be monitored. A tire with insufficient pressure results in vehicle instability when driving, thus increasing the risk of an accident.

The tire pressure values stored at the last restart will continue to be monitored. Tire pressure monitor Important safety notes If a tire pressure monitor system is installed, the vehicle's wheels have sensors that monitor the tire pressures in all four tires. The tire pressure monitor warns you if the pressure drops in one or more of the tires. The tire pressure monitor only functions if the correct wheel electronics units are installed on all wheels. The tire pressure monitor has a yellow warning lamp in the instrument cluster for indicating pressure loss/malfunctions (USA) or pressure loss (Canada). Whether the warning lamp flashes or lights up indicates whether a tire pressure is too low or the tire pressure monitoring system is malfunctioning: Rif the warning lamp is lit continuously, the tire pressure on one or more tires is significantly too low. The tire pressure monitor is not malfunctioning. RUSA only: if the warning lamp flashes for 60 seconds and then remains lit constantly, the tire pressure monitor is malfunctioning. 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 pressure, even if underinflation has not reached the level to trigger illumination of the TPMS low tire pressure telltale. USA only: Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one 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. i USA only: Z 319 Wheels and tires Tire pressure 320 Tire pressure If the tire pressure monitor is malfunctioning, it may take more than 10 minutes for the tire pressure warning lamp to inform you of the malfunction by flashing for 60 seconds and then remaining lit. When the malfunction has been rectified, the tire pressure warning lamp goes out after driving for a few minutes. Information on tire pressures is displayed in the multifunction display. After a few minutes of driving, the current tire pressure of each tire is shown in the multifunction display. Wheels and tires i The tire pressure values indicated by the on-board computer may differ from those measured at a gas station with a pressure gauge.

After a teach-in period, the tire pressure monitor automatically recognizes new wheels or new sensors. If a clear allocation of the tire pressure values to the individual wheels is not possible, the Tire Pressure Monitor Active 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 Tire pressure monitor warning messages i If the wheel positions on the vehicle are interchanged, the tire pressures may be displayed for the wrong positions for a short time. This is rectified after a few minutes of driving, and the tire pressures are displayed for the correct positions. Restarting the tire pressure monitor G WARNING It is the driver's responsibility to set the tire pressure to the recommended cold tire pressure. Underinflated tires affect the ability to steer or brake the vehicle. You might lose control over the vehicle. When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring. In most cases, the tire pressure monitoring system recognizes the new reference values automatically. However, you can also define reference values manually as described here: X Additional tire pressure values for driving at high speeds or with heavy loads can be found in the tire pressure table on the inside of the fuel filler flap.

Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. Wheels and tires Two instruction labels on your vehicle show the maximum possible load. (1) The Tire and Loading Information placard on the B-pillar on the driver's side. The Tire and Loading Information placard shows the maximum permissible number of occupants and the maximum permissible vehicle load. It also contains details of the tire sizes and corresponding pressures for tires mounted at the factory. (2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicle identification plate informs you of the gross vehicle weight rating. It is made up of the vehicle weight, all vehicle occupants, the fuel and the cargo. You can also find information about the maximum gross axle weight rating on the front and rear axle. The maximum gross axle weight rating is the maximum weight that can be carried by one axle (front or rear axle). Never exceed the maximum load or the maximum gross axle weight rating for the front or rear axle. : B-pillar, driver's side Maximum permissible gross vehicle weight rating i The specifications shown on the Tire and Loading Information placard in the illustration are examples. The maximum permissible gross vehicle weight rating is vehicle-specific and may differ from that in the illustration. You can find the valid maximum permissible gross vehicle weight rating for your vehicle on the Tire and Loading Information placard. X The Tire and Loading Information placard gives you details on maximum permissible gross vehicle weight rating :: "The gross weight of occupants and luggage must never exceed XXX kilograms or XXX pounds." The gross weight of all vehicle occupants, cargo, 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. X Step 4: The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs and there will be five 150 lbs passengers in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 - 750 (5 x 150) = 650 lbs). X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in step 4. X Step 6 (if applicable): If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle (Y page 325). Maximum number of seats : determines the maximum number of occupants allowed to travel in the vehicle. This information can be found on the Tire and Loading Information placard. 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. X Step 2: Determine the combined weight of the driver and passengers that will be riding in your vehicle. X Step 3: Subtract the combined weight of the driver and passengers from XXX kilograms or XXX lbs.

Details can be found on the vehicle identification plate on the B-pillar on the driver's side (Y page 322). Gross vehicle weight: the gross weight of the vehicle, all passengers, cargo and trailer load/noseweight (if applicable) must not exceed the permissible gross vehicle weight. Gross axle weight rating: the maximum permissible load 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. 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 G WARNING Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. Trailer load/noseweight The trailer load/noseweight affects the gross weight of the vehicle. If a trailer is attached, the trailer load/noseweight is included in the load along with occupants and luggage. The trailer load/noseweight is usually 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 325). 326 Uniform Tire Quality Grading Standards North America have these grades branded on the sidewall. i The actual values for tires are vehiclespecific 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 specific to Wheels and tires each vehicle and may deviate from the values in the illustration. Maximum tire load : is the maximum permitted weight for which the tire is approved. Further information on tire loads (Y page 327). Tread wear Traction Temperature 200 A AA All passenger car tires must conform to the statutory safety requirements in addition to these grades. Tread wear Uniform Tire Quality Grading Standards Overview of Tire Quality Grading Standards The Uniform Tire Quality Grading is a U.S. Government requirement. Their purpose is to provide drivers with consistent and reliable information regarding tire performance. Tire manufacturers are required to grade tires using three performance factors: tread wear :, tire traction ;, and temperature resistance =. Although not a Government of Canada requirement, all tires made for sale in The tread wear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified U.S. Government test 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 Tire labeling G WARNING If ice has formed on the road, tire traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution. 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 tire tread depth of 1/6 in (4 mm) for all four winter tires (Y page 312) to maintain normal driving characteristics in winter. Winter tires can reduce the braking distance on snow covered surfaces in comparison to 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. controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law. Tire labeling Tire labeling overview 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 : Uniform tire Quality Grading Standard (Y page 331) ; DOT, Tire Identification Number (Y page 330) = Maximum tire load (Y page 325) ?

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. Nominal aspect ratio: aspect ratio ; is the size ratio between the tire height and the 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 which specifies the maximum load-bearing capacity of a tire. G WARNING The tire load rating must always be at least half of the GAWR of your vehicle. Otherwise, sudden tire failure may be the result which could cause an accident and/or serious injury to you or others. Always replace rims and tires with rims and tires having the same specifications (designation, manufacturer and type) as shown on the original part. G WARNING Do not overload the tires by exceeding the specified load limit as indicated on the Tire and Loading Information placard on the driver's door B-pillar. Overloading the tires can overheat them, possibly causing a blowout. Overloading the tires can also result in handling or steering problems, or brake failure. Tire labeling G WARNING Even when permitted by law, never operate a vehicle at speeds greater than the maximum speed rating of the tires. Exceeding the maximum speed for which tires are rated can lead to sudden tire failure, causing loss of vehicle control and possibly resulting in an accident and/or serious personal injury and possible death, for you and for others. Regardless of the speed rating always observe the speed limits. Drive carefully and adapt your driving style to the traffic conditions. Summer tires Index Speed rating Q Up to 100 mph (160 km/h) R Up to 106 mph (170 km/h) S Up to 112 mph (180 km/h) T Up to 118 mph (190 km/h) H Up to 130 mph (210 km/h) V Up to 149 mph (240 km/h) W Up to 168 mph (270 km/h) Y Up to 186 mph (300 km/h) ZR...Y Up to 186 mph (300 km/h) Summer tires Index Speed rating ZR...(..Y) Above 186 mph (300 km/h) ZR Above 149 mph (240 km/h) ROptionally, tires with a maximum speed of over 149 mph (240 km/h) may have "ZR" in the size description depending on the manufacturer (e.g. 245/40 ZR 18). The service specifications consist of load bearing index A and speed rating B. RIf the size description of your tire includes "ZR" and there are no service specifications, ask the tire manufacturer in order to find out the maximum speed. If a service specification is available, the maximum speed is limited according to the speed rating in the service specification. Example: 245/40 ZR 18 97 Y. In this example, "97 Y" is the service specification. The letter "Y" represents the speed rating and the maximum speed of the tire is limited to 186 mph (300 km/h). REvery tire that has a maximum speed above 186 mph (300 km/h) must have "ZR" in the size description and the service specification must be given in brackets. Example: 275/40 ZR 18 (99 Y). The speed rating "(Y)" shows that the maximum speed of the tire is above 186 mph (300 km/h). Ask the tire manufacturer to find out the maximum speed.

GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross weight of a fully loaded vehicle (the weight of the vehicle including all accessories, occupants, fuel, luggage and the drawbar noseweight, if applicable). The gross vehicle weight rating is specified on the vehicle identification plate on the B-pillar on the driver's side. Maximum loaded vehicle weight Wheels and tires Rim This is the part of the wheel on which the tire is mounted. The maximum weight is the sum of the curb weight of the vehicle, the weight of the accessories, the total load limit and the weight of the optional equipment installed at the factory. GAWR (Gross Axle Weight Rating) The GAWR is the maximum permissible axle weight. The actual load on an axle must never exceed the gross axle weight rating. The gross axle weight rating can be found on the vehicle identification plate on the B-pillar on the driver's side. Speed rating The speed rating is part of the tire identification. It specifies the speed range for which the tire is approved. GVW (Gross Vehicle Weight) The gross vehicle weight comprises the weight of the vehicle including fuel, tools, the spare wheel, accessories installed, occupants, luggage and the drawbar noseweight, if applicable. The gross vehicle weight must not exceed the gross vehicle weight rating GVWR as specified on the Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa is the equivalent of 1 psi. Another unit for tire pressure is bar. There are 100 kilopascals (kPa) to 1 bar. Load index In addition to the load bearing index, the load index may also be imprinted on the sidewall of the tire. This specifies the load bearing capacity more precisely. Curb weight The weight of a vehicle with standard equipment including the maximum capacity of fuel, oil and coolant. It also includes the airconditioning system and optional equipment if these are installed in the vehicle, but does not include passengers or luggage. Definition of terms for tires and loading The maximum load rating in kilograms or pounds is the maximum weight for which a tire is approved. Maximum permissible tire pressure Maximum permissible tire pressure for one tire. Maximum load on one tire Maximum load on one tire. This is calculated by dividing the maximum axle load of one axle by two. PSI (pounds per square inch) A standard unit of measure for tire pressure. Aspect ratio Relationship between tire height and tire width in percent. Tread The part of the tire that comes into contact with the road. Bead The tire bead ensures that the tire sits securely on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from the wheel rim. Sidewall The part of the tire between the tread and the bead. Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard part and more than 2.3 kilograms (5 lbs). These optional extras, such as highperformance brakes, level control, a roof rack or a high-performance battery, are not included in the curb weight and accessory weight. Tire pressure This is pressure inside the tire applying an outward force to each square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. TIN (Tire Identification Number) This is a unique identifier which can be used by a tire manufacturer to identify tires, for example for a product recall, and thus identify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire type code and the manufacturing date. Tire pressure of cold tires The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has not been driven more than 1 mile (1.6 km).

Z Wheels and tires Maximum load rating 333 334 Changing a wheel Traction Traction is the result of friction between the tires and the road surface. Treadwear indicators Narrow bars (tread wear bars) that are distributed over the tire tread. If the tire tread is level with the bars, the wear limit of 1/16 in (1.6 mm) has been reached. Occupant distribution Wheels and tires The distribution of occupants in a vehicle at their designated seating positions. Total load limit Rated cargo and luggage load plus 68 kilograms (150 lbs) times the vehicle's designated seating capacity. Changing a wheel Flat tire The "Breakdown assistance" section (Y page 293) contains information and notes on how to deal with a flat tire. It also provides instructions on changing a wheel or mounting the spare wheel/emergency spare wheel. Interchanging the wheels G WARNING Rotate front and rear wheels only if the tires are of the same dimension. If your vehicle is equipped with mixed-size tires (different tire dimensions front vs. rear), tire rotation is not possible. G WARNING Have the tightening torque checked after changing a wheel. Wheels could become loose if not tightened with a torque of 96 lb-ft (130 Nm). Only use genuine Mercedes-Benz wheel bolts specified for your vehicle's rims. 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 this is not available, the tires should then be replaced every 3000 to 6000 miles (5000 to 10,000 km), or earlier if the tire wear requires this. 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 interchanged. Check the tire pressures. Information on changing a wheel and mounting the spare wheel (Y page 293). ! 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. Always have the tires changed at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center. 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. Wheel and tire combinations 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 Do not use power washers with circular-jet nozzles (dirt grinders) to clean your vehicle, in particular the tires. You could otherwise damage the tires and cause an accident. Wheel and tire combinations Please bear the following in mind ! For safety reasons, Mercedes-Benz recommends that you only use Tires and wheels which have been approved by Mercedes-Benz specifically for your vehicle. These tires have been specially adapted for use with the control systems, such as ABS or ESP®, and are marked as follows: RMO = Mercedes-Benz Original RMOE = Mercedes-Benz Original Extended (tires featuring run-flat characteristics) RMO1 = Mercedes-Benz Original (only certain AMG tires) Mercedes-Benz Original Extended tires may only be used on wheels that have been specifically approved by Mercedes-Benz. Only use tires, wheels or accessories tested and approved by Mercedes-Benz. Certain characteristics, e.g. handling, vehicle noise emissions or fuel consumption, may otherwise be adversely affected. In addition, when driving with a load, tire dimension variations could cause the tires to come into contact with the bodywork and axle components. This could result in damage to the tires or the vehicle. Mercedes-Benz accepts no liability for damage resulting from the use of tires, wheels or accessories other than those tested and approved. Further information about tires, wheels and approved combinations can be obtained from any authorized Mercedes-Benz Center. i The recommended tire pressures for various operating conditions can be found: Ron the Tire and Loading Information placard with the recommended tire pressures on the B-pillar on the driver's side Rin the tire pressure table on the inside of the fuel filler flap. Observe the instructions about the recommended tire pressure and the various operating conditions (Y page 313). Check tire pressures regularly, and only when the tires are cold. Comply with the maintenance recommendations of the tire manufacturer in the vehicle document wallet. i Notes on the vehicle equipment – always equip the vehicle: Rwith tires of the same size on a given axle (left/right) Rwith the same type of tires at a given time (summer tires, winter tires, MOExtended tires) i On the following pages, you can find information on approved wheel rims and tire sizes for equipping your vehicle with winter tires. Winter tires are not available ex factory as standard equipment or optional extras.

It burns violently and can cause serious personal injury. Never allow sparks, flames or smoking materials near gasoline. Turn off the engine before refueling. Whenever you are around gasoline, avoid inhaling fumes and any skin or clothing contact. Direct skin contact with fuels and the inhalation of fuel vapors are damaging to your health. Premium-grade unleaded gasoline ! To ensure the longevity and full performance of the engine, only premiumgrade unleaded gasoline may be used. If there is no premium-grade unleaded gasoline available and regular-grade unleaded gasoline may be used; please observe the following precautions: Ronly fill the fuel tank to half full with regular-grade unleaded gasoline and fill the rest with premium-grade unleaded gasoline as soon as possible. Rdo not drive at the maximum speed. Ravoid sudden acceleration. Rif the vehicle is carrying a light load, e.g. two passengers without luggage, do not allow the engine to rev above 3,000 rpm. Rif the vehicle is fully loaded or is being operated in mountainous terrain, do not depress the accelerator pedal further than Ô of the pedal travel. Flexible fuel vehicles Important safety notes Flexible fuel vehicles can be recognized by the sticker on the inside of the filler flap. Flexible fuel vehicles can be operated with premium-grade unleaded gasoline and ethanol (E85) or a mixture of both. Ethanol fuel (E85) is a mixture of approximately 85% ethanol and 15% unleaded gasoline. G WARNING Ethanol fuel (E85) and its vapors are highly flammable, poisonous and highly combustible. Ethanol fuel causes serious injury if it ignites, if it comes into contact with your skin or if you inhale the vapors. Avoid inhaling ethanol vapors and ethanol coming into contact with your skin. Before refueling, extinguish all naked flames. Never allow sparks or smoking materials near ethanol. Changing the fuel type For best performance and drivability, it is recommended that you use either one or the other fuel. Avoid alternating regularly between the two different types of fuel. When changing between the fuel types, ensure that the following conditions are met: Rthe fuel level is below half full. Rthe fuel level is above the reserve level. This is identifiable by the fuel tank reserve warning lamp not being lit. Ryou add more than 5 gallons (20 liters) of fuel. Ryou switch off the engine before refueling. Rthe engine is started and runs for at least five minutes immediately after refueling. These precautions should prevent the possibility of engine difficulties arising from changing to a different fuel type. If the engine still doesn't run correctly, refuel with at least 3 US gal (12 l) of premium-grade unleaded gasoline. This may improve the running of the engine. Z Technical data Fuel 347 348 Service products and capacities Fuel consumption Ethanol (E85) contains less energy per gallon than gasoline. To ensure that the engine performance with ethanol (E85) is similar to that when using gasoline, the engine must burn more ethanol. As a result, it is to be expected that fuel consumption will increase when using ethanol fuel (E85), compared to gasoline. Technical data Maintenance Inform your authorized Mercedes-Benz Center that you are operating or have operated the vehicle with ethanol (E85). Low outside temperatures Starting times may significantly increase at temperatures below 32 ‡ (0 † ). At low outside temperatures, Mercedes-Benz recommends the use of an auxiliary heater. For further information, consult an authorized Mercedes-Benz Center. Rough idling may also be experienced at low outside temperatures until the engine is fully warmed up. Ethanol (E85) is unsuitable for use if outside temperatures fall below 14 ‡ (-10 † ). High outside temperatures At outside temperatures above 95 ‡ (35 † ), the time required for the starting procedure may increase and be accompanied by rough idling following the start. Fuel requirements Use only premium-grade unleaded gasoline. The octane number should be at least 91. Details can be found on the gas pump. The octane number is the average value of the Research Octane Number (RON) and the Motor Octane Number (MON): (RON + MON) / 2, also known as knock resistance. Reformulated gasoline (RFG) and/or unleaded gasoline with additives can be used. However, the concentration of additives in the fuel must be less than 10%, e.g. REthanol RTAME RETBE RIPA RTBA For MTBE, the concentration should not exceed 15%. The concentration of methanol in gasoline including other additives must not exceed 3%. Using mixtures of methanol and ethanol is not permitted. Gasohol, a mixture of 10% ethanol and 90% unleaded gasoline, can be used. All of these mix fuels must fulfill the fuel requirements, e.g.: Rknock resistance point Rvapor pressure Rboiling Additives in gasoline One of the main problems of poor fuel quality is the forming of deposits that are created during the gasoline combustion process. Mercedes-Benz recommends that you use fuel brands that have the additives. Deposits may form if you use fuels without additives over a longer period of time. These deposits are most likely to form on the inlet valves and in the combustion chamber. This could lead to engine problems, e.g.: Rlonger engine warm-up phase idle Rengine noise Rmisfiring Rloss of power Carbon deposits may form if the availability of gasoline with relevant additives is insufficient (in certain regions). In this case, Mercedes-Benz recommends the use of Runeven Service products and capacities ! Do not refuel with low-grade fuel and do not use fuel additives that are not tested and approved for Mercedes-Benz vehicles. Damage to or malfunctions of the fuel system may otherwise occur. Engine oil Please bear the following in mind The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center. Or visit http://www.mbusa.com (USA only). ! Never use engine oil or an oil filter of a specification other than is necessary to fulfill the prescribed service intervals. Do not change the engine oil or oil filter in order to achieve longer replacement intervals than those prescribed. You could otherwise cause engine damage or damage to the exhaust gas aftertreatment. Follow the instructions in the service interval display regarding the oil change. Otherwise, you may damage the engine and the exhaust gas aftertreatment. 34 Canada The table shows which engine oils have been approved for your vehicle.

Additives ! Do not use any additives in the engine oil. This could damage the engine. Engine oil viscosity Viscosity describes the flow characteristics of a fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity means that it is thin. Select an engine oil with an SAE (viscosity) classification suitable for the prevailing outside temperatures. The following table shows the correct SAE classification to be used. The low-temperature characteristics of engine oils can deteriorate significantly, e.g. as a result of aging, soot and fuel deposits. It is therefore strongly recommended that you carry out regular oil changes using an approved engine oil with the appropriate SAE classification. only. only SAE 0W-40 or SAE 5W-40 engine oils may be used. 35 Restriction: Z Technical data additives that have been approved for Mercedes-Benz vehicles. Consult an authorized Mercedes-Benz Center or go to the Internet site http://www.mbusa.com (USA only) for a list of approved products. Comply with the instructions for use on the product label. Do not mix other fuel additives with fuel. This causes unnecessary costs and could damage the engine. 349 350 Service products and capacities Coolant Important safety notes The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Rcorrosion protection protection Rraising the boiling point The engine cooling system is filled at the factory with coolant that contains an antifreeze/corrosion inhibitor that ensures protection down to approximately -35 ‡ (-37 †). Rantifreeze Refrigerant of the air-conditioning system The air-conditioning system is filled with R134a refrigerant and a special PAG lubricant. ! Never use refrigerant R 12 (CFC) or Technical data mineral lubricants. Otherwise, you could damage the air-conditioning system. Brake fluid G WARNING Over a period of time, the brake fluid absorbs moisture from the air; this lowers its boiling point. If the boiling point of the brake fluid is too low, vapor pockets may form in the brake system when the brakes are applied hard (e.g. when driving downhill). This would impair braking efficiency. You should have the brake fluid renewed at regular intervals. The brake fluid change intervals can be found in the Service Booklet. Only use brake fluid approved by MercedesBenz. Information about approved brake fluids can be obtained from any authorized Mercedes-Benz Center or on the Internet at http://bevo.mercedes-benz.com. ! Only add coolant that has been premixed with the desired antifreeze protection. Otherwise, the engine could be damaged. Further information on coolants and on filling can be found in the Mercedes-Benz Specifications for Service Products, MB Approval 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. You can also consult an authorized Mercedes-Benz Center. ! Always use a suitable coolant mixture, even in countries where high temperatures prevail. Otherwise, the engine cooling system is not sufficiently protected from corrosion and overheating. If the coolant has antifreeze protection down to -35 ‡ (-37 †), the boiling point of the coolant under operating conditions is approximately 266 ‡ (130 †). Your vehicle has a range of aluminum components. Aluminum components in the engine make it necessary to use antifreeze/ corrosion inhibitor coolant that has been specifically formulated to protect the aluminum parts. Using other antifreeze/ corrosion inhibitors without these characteristics affects the service life. The coolant must be used throughout the year in order to maintain the necessary corrosion Vehicle data Rbe at least 50%. This will protect the engine cooling system against freezing down to approximately -35 ‡ (-37 † ). Rnot exceed 55% (antifreeze protection to -49 ‡ [-45 † ]); otherwise, heat will not dissipate as effectively. If the coolant level is too low, MB 325.0 or 326.0 anticorrosion/antifreeze should be added. Have the engine cooling system checked for possible leaks. Use MB SummerFit windshield washer concentrate at temperatures above freezing: X Mix 1 part MB SummerFit with 100 parts water. Use MB WinterFit windshield washer concentrate at temperatures below freezing: X At temperatures down to 14 ‡ (Ò 10 †): mix 1 part MB WinterFit with 2 parts water.
