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 Occupant safety In this section, you will learn the most important facts about the restraint system components of the vehicle. The restraint system consists of: Rseat belts restraint systems RLATCH-type (ISOFIX) child seat anchors Additional protection is provided by: Rchild RSRS (Supplemental Restraint System) head restraints/NECK-PRO luxury head restraints RPRE-SAFE® 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 i See "Children in the vehicle" for information on infants and children traveling with you in the vehicle restraint systems for infants and children (Y page 58). SRS (Supplemental Restraint System) Introduction SRS consists of: 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 R6 RAir effect of the forces to which occupants are subjected during an accident. SRS warning lamp G WARNING The SRS self-check has detected a malfunction if the 6 SRS indicator lamp: Rdoes not light up at all not go out after approximately four seconds after the engine is started Rlights up after the engine is started or while the vehicle is in motion For your safety, Mercedes-Benz strongly recommends that you have the system checked as soon as possible at a qualified specialist workshop. SRS may otherwise fail to activate when it is needed in the event of an accident, which could lead to serious or fatal injuries. SRS might also be activated unexpectedly and unnecessarily, which could also result in injury. In addition, work carried out improperly on SRS may render SRS inoperative or cause unintended air bag deployment. Work on the SRS system should only be carried out by qualified specialist personnel. Consult a qualified specialist workshop. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for further information, contact our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372). Rdoes 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 SRS 6 indicator lamp goes out while the engine is running. Z Safety tamper with electronic components or their software. 39 40 Occupant safety Safety guidelines for seat belts, Emergency Tensioning Devices (ETDs) and air bags Safety 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. PRESAFE® has electrically operated reversible belt tensioners in addition to the pyrotechnic ETDs. 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. to the: - padded steering wheel boss - knee bag covers - front-passenger air bag cover - outer side of front seat bolsters - side trim next to the rear seat backrest - roof lining trim RDo not install additional electrical/ electronic equipment on or near SRS components and wiring. RKeep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.). RDo not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed. RAir bag system components will be hot after an air bag has inflated. Do not touch them. RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat. RImproper repair work on the SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. RFor your protection and the protection of others, when scrapping the air bag unit or ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz Center. RGiven the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment. If you sell your vehicle, Mercedes-Benz strongly recommends that you inform the subsequent owner that the vehicle is equipped with SRS. Also, refer them to the applicable section in the Operator's Manual. Air bags Important safety notes G WARNING 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 knee bags) Rside impacts (side impact air bags, window curtain air bags and pelvis air bags) Rrollover (window curtain air bags) However, no system available today can completely eliminate injuries and fatalities. When the air bags are deployed, a small amount of powder is released. The powder generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. In order to prevent potential breathing difficulties, you should leave the vehicle as soon as it is safe to do so. If you have any breathing difficulty but cannot get out of the vehicle after the air bag inflates, then get fresh air by opening a window or door. G WARNING In order to reduce the potential danger of injuries caused during the deployment of the front air bags, the driver and front passenger must always be correctly seated and wear their seat belts. For maximum protection in the event of a collision, you must always be in the normal seat position with your back against the backrest. Fasten your seat belt and make sure that it is correctly positioned on your body. As the air bag inflates with considerable speed and force, a proper seating position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag, as it inflates with great force instantaneously: Rsit with the seat belt fastened correctly and in a position that is as upright as possible with your back against the backrest. Rmove the driver's seat as far back as possible, still permitting proper operation of vehicle controls. The distance from the center of the driver's chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm). You should be able to accomplish this by adjusting the seat and steering wheel. If you have any difficulties, please contact an authorized Mercedes-Benz Center. Rdo not lean your head or chest close to the steering wheel or dashboard. Ronly hold the steering wheel on the outside. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury if the driver front air bag inflates. Radjust the front-passenger seat as far back as possible from the dashboard when the seat is occupied. Roccupants, especially children, should never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious or fatal injuries should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint or booster seat recommended for the size and weight of the child. Failure to follow these instructions can result in severe injuries to you or other occupants. Z 41 Safety Occupant safety 42 Occupant safety Safety 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. 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. The air bags are deployed if the air bag control unit detects the need for deployment. Only in the event of such a situation will the air bags provide their supplemental protection. If the driver and front passenger do not wear their seat belts, it is not possible for the air bags to provide their supplemental protection. In the event of other types of impacts and impacts below air bag deployment thresholds, the air bags will not deploy. The driver and 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 passengers 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 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. The front air bags increase protection for the driver's and front-passenger's head and chest. 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 Rdepending on whether the seat belt is being used Rindependently of other air bags in the vehicle If the vehicle overturns, the front air bags are generally not deployed. If the system detects Rif Occupant safety child restraint system without transponders for air bag deactivation system is installed or Ra child restraint system with transponders is not properly installed. 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 45). 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. Front-passenger front air bag will only deploy if: Knee bags Safety high vehicle deceleration in a longitudinal direction, the front air bags are deployed. If a child restraint system is installed to the front-passenger seat and the 4 PASSENGER AIRBAG OFF indicator lamp does not light up on the center console: Ra Rthe system, based on the OCS weight sensor readings, has detected that the front-passenger seat is occupied.

Rthe air bag control unit predicts a high impact severity. 43 Driver's knee bag : deploys underneath the steering column and front-passenger knee bag ; underneath the glove box. They deploy together with the front air bags. They are designed to operate together with the front air bags in frontal impacts if certain thresholds are exceeded. The knee bags operate at best in conjunction with correctly positioned and fastened seat belts. Knee bags provide increased protection for the driver and front passenger against the risk of: Rknee injuries injuries Rlower leg injuries Rthigh Side impact air bags 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 the OCS senses that the frontpassenger 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, indicating that the frontpassenger front air bag is deactivated. When the OCS senses that the frontpassenger seat is classified as being empty, the 45 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the frontpassenger front air bag is deactivated. When the OCS senses that the frontpassenger 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 and then, depending on occupant weight sensor readings from the frontpassenger seat, 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 frontpassenger seat occupant is classified as an adult or someone larger than a small individual, the 45 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then go out, indicating that the front-passenger front air bag is activated. If the 45 indicator lamp is illuminated, the front-passenger front air bag and the front-passenger knee bag are deactivated and will not be deployed. If the 45 indicator lamp is not illuminated, the front-passenger front air bag and the front-passenger knee bag are activated and will be deployed: Rin the event of certain frontal impacts impact exceeds a preset deployment threshold Rindependently 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 relevant vehicle deceleration as assessed by the air bag control unit Rthe front passenger's weight category as identified by OCS G WARNING According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle's seat belt, the seat belt and Top Tether strap, or lower ISOFIX child seat retaining loops and Top Tether strap, fully in accordance with the infant or 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. Occupant safety RYour vehicle is equipped with air bag technology designed to deactivate the front-passenger front air bag and the frontpassenger knee 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 and front-passenger knee bag are 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 could be seriously injured or even killed if the front-passenger front air bag is deployed. 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 and the front-passenger knee bag may or may not be activated. 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 and the front passenger knee 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. Z Safety Note the following important information if it is necessary to carry a child on the frontpassenger seat: 47 Occupant safety Safety 48 If the SmartKey has been removed from the ignition lock or is in position 0, the 45 indicator lamp : does not light up. The Occupant Classification System (OCS) categorizes the occupant on the frontpassenger seat by means of a weight sensor. The front-passenger front air bag and the front-passenger knee bag are deactivated automatically for certain weight categories. The 45 indicator lamp shows you the current status. If the 45 indicator lamp lights up, the front-passenger air bag and the front-passenger knee bag are disabled. The system does not deactivate: Rthe side impact air bag pelvis air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices To be classified correctly, the front passenger must sit: Rthe Rwith the seat belt fastened correctly Rin a position that is as upright as possible with their back against the seat backrest Rwith their feet on the floor The OCS weight sensor reading is affected if the occupant's weight is transferred, e.g. by leaning on the armrest. If the front-passenger seat, the seat cover or the seat cushion are damaged, have the necessary repair work carried out at a qualified specialist workshop. For safety reasons, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. Both the driver and the front passenger should always observe the 45 indicator lamp to determine whether or not the front passenger is positioned correctly. Also observe the air bag display messages, which appear in the instrument cluster (Y page 235). If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The OCS may have detected that the seat: Ris empty or occupied by the weight of a typical child up to twelve months old, seated in a child restraint system Ris occupied by a small individual, such as a young teenager or a small adult Ris occupied by a child in a child restraint system whose weight is greater than that of a typical twelve month old child. These are examples of when the OCS deactivates the front-passenger front air bag and front-passenger knee bag. Deactivation takes place although the collision fulfills the criteria for deploying the driver's air bag. For further information, see "Air bag display messages" (Y page 235). System self-test 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. 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 Occupant safety Safety 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. 49 The 45 indicator lamp lights up: Rif you turn the SmartKey in the ignition lock to position 1 or 2 you press the KEYLESS-GO Start/Stop button once or twice on vehicles with KEYLESS-GO Rif an adult is seated properly on the frontpassenger seat and the OCS classifies the occupant as an adult The 45 indicator lamp goes out after approximately six seconds. If the seat is not occupied and the OCS detects that the front-passenger seat is empty, the 45 indicator lamp will continue to light up. The 45 frontpassenger front air bag warning lamp then stays lit continuously. For more information about the OCS, see "Problems with the Occupant Classification System" (Y page 50).

Seat belts Important safety notes 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. 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. 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 Always have damaged seat belts or seat belts that have been subjected to a load in an accident replaced and the anchorages checked. Only use seat belts that have been approved by Mercedes-Benz. Never tamper with seat belts. This can result in the unintended deployment of the Emergency Tensioning Devices or the failure to deploy when necessary. Do not bleach or dye seat belts, as this may severely weaken them. In the event of a collision, they may be unable to provide adequate protection. Have all work carried out only by qualified technicians. Consult a qualified specialist workshop.

Safety RU.S. i See "Children in the vehicle" (Y page 58) for further information on infants and children traveling in the vehicle as well as on child restraint systems. 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, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds and in certain rollovers (window curtain air bags and ETDs). 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. For this purpose, you can adjust the height of the seat belt outlet. RPosition the lap belt as low as possible on your hips and not across the abdomen. If the lap belt is positioned across your abdomen, it could cause serious injuries in a crash. RNever wear seat belts over rigid or breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries. RMake sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing. RNever use a seat belt for more than one person at a time. Do not fasten a seat belt around a person and another person or other objects at the same time. RSeat belts should not be worn twisted. In a crash, you would not have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries. RPregnant women should also always use a lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen. RPlace the seat backrest in a position that is as upright as possible. RCheck your seat belt during travel to make sure it is properly positioned. Occupant safety RNever Safety 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. 55 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.

Belt warning for the driver and front passenger Regardless of whether the driver's and frontpassenger seat belts have already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the engine is started. It then goes out if the driver and the front passenger have fastened their seat belts. Occupant safety Runtil the driver's or front passenger's seat belt is fastened Ronce the vehicle has exceeded a speed of 15 mph (25 km/h), in addition a warning tone will sound with increasing intensity for up to 60 seconds or until the driver's or front-passenger seat belt is fastened. If the driver/front passenger unfasten their seat belt while the vehicle is in motion, the 7 seat belt warning lamp lights up and a warning tone sounds again. The warning tone ceases after 60 seconds even if the driver or front passenger has still not fastened their seat belt. The 7 seat belt warning lamp stops flashing but remains illuminated. After the vehicle comes to a standstill, the warning tone is reactivated and the 7 seat belt warning lamp flashes again if the vehicle speed again exceeds 15 mph (25 km/h). 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 belts" (Y page 256). Emergency Tensioning Devices, belt force limiters G WARNING Pyrotechnic Emergency Tensioning Devices that have been deployed must be renewed. For your safety, when disposing of Emergency Tensioning Devices, always observe the safety instructions. These are available from any authorized Mercedes-Benz Center. The PRE-SAFE® system has electrically operated reversible pre-tensioners that do not require replacement after activation. ! 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. The seat belts are equipped with Emergency Tensioning Devices and 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. If the seat belt is also equipped with a seat belt force limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced. When triggered, seat belt force limiters help to reduce the peak force exerted by the seat belt on the vehicle occupant. The belt force limiters for the front seats are synchronized with the front air bags, which take on a part of the deceleration force. This results in the force exerted on the occupant being distributed over a greater area. The ETDs can only be activated when: Rthe ignition is switched on. restraint systems are operational; see "SRS warning lamp" (Y page 39). Rthe R Z Safety If the driver's seat belt is not fastened when 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 after six seconds the driver or front passenger have not fastened their seat belts and the doors are closed, the 7 seat belt warning lamp lights up: 57 58 Children in the vehicle Safety Rthe belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front. Rthe front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side. The ETDs on the 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: 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 Rif, in certain situations where the vehicle overturns, the system determines that it can provide additional protection If the ETDs are deployed, you will hear a bang, and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard. The 6 SRS warning lamp lights up. Children in the vehicle Child restraint systems Important safety notes 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 Children in the vehicle G WARNING Infants and small children should never share a seat belt with another occupant. In the event of 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 that are too large for a child restraint must travel in seats using normal 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. 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. Rbe G WARNING Do not carry heavy or hard objects in the passenger compartment or trunk unless they are firmly secured in place. Unsecured or improperly positioned cargo increases a child's risk of injury in the event of Rstrong braking maneuvers changes of direction Ran accident Rsudden Z Safety so, make sure the 4 5 indicator lamp is illuminated, indicating that the front 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. 59 60 Children in the vehicle Safety Further information on secure stowage of loads can be found under "Loading guidelines".

Driving safety systems Driving safety systems overview In this section, you will find information about the following driving safety systems: (Anti-lock Braking System) (Y page 64) RBAS (Brake Assist System) (Y page 64) RBAS PLUS (Brake Assist System PLUS) (Y page 65) RESP® (Electronic Stability Program) (Y page 66) REBD (electronic brake force distribution) (Y page 69) RADAPTIVE BRAKE(Y page 69) RPRE-SAFE® Brake (Y page 69) RABS Important safety notes If you fail to adapt your driving style or become distracted, the driving safety systems can neither reduce the risk of accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are Z Safety 64 Driving safety systems 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 and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully. i The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Please pay special attention to the notes on tires, recommended minimum tire tread depths, etc. (Y page 326). 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) Important safety notes i Observe the "Important safety notes" section (Y page 63). G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired. Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents. Drive on carefully. Have ABS checked immediately at a qualified specialist workshop. When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 258) and display messages which may be shown in the instrument cluster (Y page 229). 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 if you only brake gently. The yellow ! ABS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running. Braking X If ABS intervenes: continue to depress the brake pedal vigorously until the braking situation is over. X To make a full brake application: depress the brake pedal with full force. If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving. BAS (Brake Assist System) i Observe the "Important safety notes" section (Y page 63). G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking. BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. The brakes will function as usual once you release the brake pedal. BAS is deactivated. Driving safety systems i Observe the "Important safety notes" section (Y page 63). BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS. BAS PLUS provides braking assistance in hazardous situations at speeds greater than 4 mph (7 km/h) and uses radar sensor technology to assess the traffic situation. 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. BAS PLUS can also react to stationary obstacles, e.g. stopped or parked vehicles, at speeds of up to approximately 40 mph (70 km/h). To prevent a front-end collision, BAS PLUS calculates the brake force necessary if: Ryou approach an obstacle, and PLUS has detected a risk of collision For speeds above 20 mph (30 km/h): if you apply the brakes forcefully, BAS PLUS automatically increases the braking force to a level suitable for the traffic conditions. For speeds below 20 mph (30 km/h): if you apply the brakes, BAS PLUS is activated. Braking is performed as late as possible. If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are activated simultaneously. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. RBAS BAS PLUS is deactivated and the brakes function as usual, 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. Rthere For BAS PLUS to assist you when driving, the radar sensor system must be: on (Y page 223) page 243) If the radar sensor system is malfunctioning, BAS PLUS will not be available. The brake system is still available with complete brake boosting effect and BAS. Rswitched Roperational (Y 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 relative to the center of your vehicle G WARNING BAS PLUS does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering As a result, BAS PLUS may not intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. Rto Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified Z Safety BAS PLUS (Brake Assist System Plus) 65 66 Driving safety systems specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. Safety 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. Removing, altering or tampering with the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use the device in any non-approved way. Any unauthorized modification to this device could void the user's authority to operate the equipment. Observe the information on warning lamps (Y page 260) and display messages which may be shown in the instrument cluster (Y page 229). If ESP® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP® assists the driver when pulling away on wet or slippery roads. ESP® can also stabilize the vehicle during braking. If ESP® intervenes, the ÷ ESP® warning lamp flashes in the instrument cluster. If ESP® intervenes: ESP® (Electronic Stability Program) Important safety notes i Observe the "Important safety notes" section (Y page 63). G WARNING If ESP® is malfunctioning, ESP® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident. Drive on carefully. Have ESP® checked at a qualified specialist workshop. ! 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 without 4MATIC: when towing your vehicle with the rear axle raised, it is important that you observe the notes on ESP®(Y page 320). ESP® is deactivated if the å warning lamp in the instrument cluster lights up continuously when the engine is running. If the ÷ warning lamp and the å warning lamp are lit continuously, ESP® is not available due to a malfunction. X Do not deactivate ESP® under any circumstances. X Only depress the accelerator pedal as far as necessary when pulling away. X Adapt your driving style to suit the prevailing road and weather conditions. i Only use wheels with the recommended tire sizes. Only then will ESP® function properly. ETS/4ETS (Electronic Traction System) Traction control is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. On vehicles with 4MATIC, more drive torque is also transferred to the wheel or wheels with traction. Traction control remains active if you deactivate ESP®. Driving safety systems RESP® G WARNING still provides support when you brake. Rengine torque is not limited and the drive wheels are able to spin. The spinning wheels produce a cutting effect for better traction. Only deactivate ESP® in the situations described in the following. Deactivating/activating ESP® (AMG vehicles) If you deactivate ESP®, ESP® no longer stabilizes the vehicle. There is an increased risk of skidding and an accident. ! Avoid spinning the driven wheels for an extended period with ESP® deactivated. You could otherwise damage the drivetrain.

EBD (electronic brake force distribution) i Observe the "Important safety notes" section (Y page 63). G WARNING If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified specialist workshop. Observe information regarding indicator and warning lamps (Y page 258) as well as display messages (Y page 231). EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 178) and hill start assist (Y page 142). PRE-SAFE® Brake i Observe the "Important safety notes" section (Y page 63). PRE-SAFE® Brake is only available in vehicles with DISTRONIC PLUS. PRE-SAFE® Brake can help you to minimize the risk of a collision with a vehicle ahead or reduce the effects of such a collision. If PRESAFE® Brake detects 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. Above a speed of around 4 mph (7 km/h), this function warns you if you are very quickly approaching a vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action provided it is safe to do so. If the driver and front passenger have their seat belt fastened, PRE-SAFE® Brake can also brake the vehicle automatically at speeds from approximately 4 mph (7 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. Z Safety RPRE-SAFE® 69 70 Driving safety systems You can prevent the intervention of the PRESAFE® Brake at any time by: Rdepressing the accelerator pedal further kickdown Rreleasing the brake pedal. The braking action of PRE-SAFE® Brake is ended automatically if: Safety Ractivating Ryou maneuver to avoid the obstacle. Rthere is no longer any danger of a rear-end collision. Rthere is no longer an obstacle detected in front of your vehicle. With the help of the radar sensor system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. At speeds of up to 40 mph (70 km/h), PRESAFE® Brake can also detect stationary obstacles, for example, stopped or parked vehicles. If you approach an obstacle and PRE-SAFE® Brake detects a risk of a collision, the system will alert you both visually and acoustically. If you do not brake or take evasive action, the system will warn you by automatically braking the vehicle gently. If there is an increased risk of collision, preventive passenger protection measures (PRE-SAFE®) are activated (Y page 52). If, at speeds over 20 mph (30 km/h), a risk of collision remains and you do not brake, take evasive action or significantly accelerate, automatic braking may be performed up to the level of emergency braking. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided. G WARNING PRE-SAFE® Brake will initially brake your vehicle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you also brake. Automatic emergency braking cannot prevent a collision. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action. G WARNING PRE-SAFE® Brake cannot always clearly identify objects and complex traffic conditions. In these cases, PRE-SAFE® Brake may: Rgive an unnecessary warning and then brake the vehicle Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE® Brake warns you. Terminate the intervention in a non-critical driving situation. 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 relative to the center of your vehicle G WARNING PRE-SAFE® Brake does not react: Rto people or animals oncoming vehicles Rto crossing traffic Rwhen cornering Rto As a result, PRE-SAFE® Brake may neither give warnings nor intervene in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake. In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself. X To activate/deactivate: activate or deactivate PRE-SAFE® Brake in the onboard computer (Y page 218). When PRE-SAFE® Brake is activated, the Ä symbol appears in the multifunction display, as long as the HOLD function is deactivated (Y page 178). On vehicles with the Active Parking Assist driving system, the Ä symbol is displayed when position P is engaged or you are driving faster than 22 mph (35 km/h). For PRE-SAFE® Brake to assist you when driving, the radar sensor system must be switched on (Y page 223) and be operational.

G WARNING Make sure that the back of your head is supported at eye level by the central area of the head restraint. If your head is not supported correctly by the head restraint, you could suffer a severe neck injury in the event of an accident. Never drive if the head restraints are not engaged and set correctly. 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.

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 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. !

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions. i Read the information on qualified Climate control specialist workshops: (Y page 24). Overview of climate control systems Important safety notes G WARNING Observe the settings recommended on the following pages. The windows could otherwise fog up. This could prevent you from observing the traffic conditions, thereby causing an accident. G WARNING Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at a qualified specialist workshop. Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control is only operational when the engine is running. The system only works optimally when the side windows and the roof are closed. The residual heat function can only be activated or deactivated with the ignition switched off (Y page 133). i Ventilate the vehicle for a brief period during warm weather, e.g. using the convenience opening feature (Y page 88). 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 Maintenance Booklet. Since the replacement interval depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet. Overview of climate control systems 125 Climate control Control panel for dual-zone climate control Canada only : Sets the temperature, left (Y page 130) ; Defrosts the windshield (Y page 131) = Switches the ZONE function on/off (Y page 131) ?

Breaking-in notes Important safety notes New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. The first 1,000 miles (1,500 km) The more you look after the engine when it is new, the more satisfied you will be with its performance in the future. should therefore drive at varying vehicle and engine speeds for the first 1,000 miles (1,500 km). RAvoid heavy loads, e.g. driving at full throttle, during this period. RChange gear in good time, before the tachometer needle is Ô of the way to the red area of the tachometer. RDo not manually shift to a lower gear to brake the vehicle. RIf possible, do not depress the accelerator pedal past the point of resistance (kickdown). ROnly select shift ranges 3, 2 or 1 when driving slowly, e.g. in mountainous terrain. After 1,000 miles (1,500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. Additional breaking-in notes for AMG vehicles: RDo not drive faster than 85 mph (140 km/h) for the first 1000 miles (1500 km). ROnly allow the engine to reach a maximum engine speed of 4500 rpm briefly. RChange gear in good time. i You should also observe these notes on running in if the engine or parts of the drive train on your vehicle have been replaced. i Always observe the respective speed limits. AMG vehicles with rear axle locking differential Your vehicle is equipped with a self-locking differential on the rear axle. To improve the protection of the differential on the rear axle, change the oil after a break-in distance of 2,000 miles (3,000 km). This oil change extends the service life of the differential. Have the oil change carried out at a qualified specialist workshop.

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 ft (approximately 14 m) a second when it is traveling at only 30 mph (approximately 50 km/h). Drive sensibly – save fuel Parking the vehicle for a long period If you leave the vehicle parked for longer than four weeks, the battery may be damaged by exhaustive discharging. If you leave the vehicle parked for longer than six weeks, the vehicle may suffer damage as a result of lack of use. X Visit a qualified specialist workshop and seek advice. i You can obtain information about trickle chargers from a qualified specialist workshop. 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 Maintenance Booklet or by the service interval display. Z Driving and parking They could also operate the vehicle's equipment. There is a risk of an accident and injury. When leaving the vehicle, always take the SmartKey with you and lock the vehicle. Never leave children unsupervised in the vehicle. 159 160 Driving tips Driving and parking 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. Exhaust check 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 if they are serviced exactly in accordance with the manufacturer's specifications. Only have work on the engine carried out by qualified and authorized Mercedes-Benz technicians. The engine settings must not be changed under any circumstances. Furthermore, all specific service work must be carried out at regular intervals and in accordance with the Mercedes-Benz service requirements. Details can be found in the Maintenance Booklet. ECO display 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. Example: ECO display The ECO display gives you information on how economical your driving style is. The ECO display assists you in achieving the optimum driving style in terms of consumption, taking the actual and selected conditions into consideration. Your driving style can Driving tips RAcceleration RConstant RCoasting The percent value is the average value of the three bars. The three bars and the mean value begin at the value of 50%. A higher percentage indicates a more economical driving style. The ECO display does not provide any information on the actual consumption. A fixed percentage count in the ECO display does not indicate a fixed consumption figure in l/100 km. Apart from driving style, consumption is dependent on many factors such as, e.g.: RLoad RTire pressure start RChoice of route RElectrical consumers switched on These factors are not taken into consideration by the ECO display. The evaluation of your driving style is carried out using the following three categories: Acceleration (evaluation of all acceleration) Constant (evaluation of driving style at any time) The bar fills up: The bar empties: Constant speed and Speed variations avoidance of unnecessary acceleration and deceleration Coasting (evaluation of total deceleration) The bar fills up: The bar empties: Drive with care and Frequent braking remove your foot from the accelerator pedal in good time: the vehicle can coast without braking RCold The bar fills up: Moderate acceleration, especially at high speeds The bar empties: Sporty acceleration i An economical driving style specially requires driving at moderate engine speeds. Achieving a higher value in the categories "Acceleration" and "Constant": Robserve the gearshift recommendations. Rdrive in drive program E. i On longer journeys, e.g. on highways, the only the bar in the "Constant" category changes. i The ECO display calculates the driving style from the start of the journey to the end. For this reason, the bars change dynamically at the beginning of the journey. On longer journeys, there are fewer changes. For more dynamic changes, carry out a manual reset.

The ECO display consists of three bars: 161 162 Driving tips Braking Important safety notes Driving and parking G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. There is an increased danger of skidding and accidents. Do not shift down for additional engine braking on a slippery road surface. Downhill gradients ! On long and steep gradients, you must reduce the load on the brakes by shifting early to a lower gear. This allows you to take advantage of the engine braking effect and helps avoid overheating and excessive wear of the brakes. When you take advantage of the engine braking effect, a drive wheel may not turn for some time, e.g. on a slippery road surface. This could cause damage to the drive train. This type of damage is not covered by the Mercedes-Benz warranty. Heavy and light loads G WARNING If you rest your foot on the brake pedal while driving, the braking system can overheat. This increases the stopping distance and can even cause the braking system to fail. There is a risk of an accident. Never use the brake pedal as a footrest. Never depress the brake pedal and the accelerator pedal at the same time. ! Depressing the brake pedal constantly results in excessive and premature wear to the brake pads. If the brakes have been subjected to a heavy load, do not stop the vehicle immediately, but drive on for a short while. This allows the airflow to cool the brakes more quickly. Wet roads If you have driven for a long time in heavy rain without braking, there may be a delayed reaction from the brakes when braking for the first time. This may also occur after the vehicle has been washed or driven through deep water. You have to depress the brake pedal more firmly. Maintain a greater distance from the vehicle in front. After driving on a wet road or having the vehicle washed, brake firmly while paying attention to the traffic conditions. This will warm up the brake discs, thereby drying them more quickly and protecting them against corrosion. Limited braking performance on salttreated roads If you drive on salted roads, a layer of salt residue may form on the brake discs and brake pads. This can result in a significantly longer braking distance. RBrake occasionally to remove any possible salt residue. Make sure that you do not endanger other road users when doing so. RCarefully depress the brake pedal and the beginning and end of a journey. RMaintain a greater distance to the vehicle ahead. Servicing the brakes 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. G WARNING Make sure that you do not endanger other road users when you apply the brakes. ! If the red brake warning lamp lights up in the instrument cluster and you hear a warning tone while the engine is running, the brake fluid level may be too low. Observe additional warning messages in the multifunction display. The brake fluid level may be too low due to brake pad wear or leaking brake lines. Have the brake system checked immediately. This work should be carried out at a qualified specialist workshop. ! 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 one of the axles raised. Braking maneuvers triggered automatically by ESP® may seriously damage the brake system. All checks and maintenance work on the brake system must be carried out at a qualified specialist workshop. Consult a qualified specialist workshop to arrange this. Have brake pads installed and brake fluid replaced at a qualified specialist workshop. If the brake system has only been subject to moderate loads, you should test the functionality of your brakes at regular intervals. To do so, press firmly on the brake pedal when driving at a high speed. This improves the grip of the brake pads. You can find a description of Brake Assist (BAS) on (Y page 64) or of BAS PLUS on (Y page 65). AMG high-performance and ceramic brakes The high-performance brake system is installed only on the CLS 63 AMG. The AMG brake systems are 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. New and replaced brake pads and discs only reach their optimum braking effect after several hundred kilometers of driving. Compensate for this by applying greater force to the brake pedal. Keep this in mind, and adapt your driving and braking accordingly during this break-in period. Excessive heavy braking results in correspondingly high brake wear. Observe the brake system warning lamp in the instrument cluster and note any brake status messages in the multifunction display. For Z 163 Driving and parking Driving tips 164 Driving tips Driving and parking high-performance driving in particular, it is important to maintain and have the brake system checked regularly. Driving on wet roads Hydroplaning If water has accumulated to a certain depth on the road surface, there is a danger of hydroplaning occurring, even if: Ryou drive at low speeds. tires have adequate tread depth. For this reason, in the event of heavy rain or in conditions in which hydroplaning may occur, you must drive in the following manner: Rthe Rlower your speed. ruts. Rbrake carefully. Ravoid Driving on flooded roads ! Do not drive through flooded areas. Check the depth of any water before driving through it. Drive slowly through standing water. Otherwise, water may enter the vehicle interior or the engine compartment. This can damage the electronic components in the engine or the automatic transmission. Water can also be drawn in by the engine's air suction nozzles and this can cause engine damage. Winter driving Important safety notes G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. There is an increased danger of skidding and accidents. Do not shift down for additional engine braking on a slippery road surface. G DANGER If the exhaust pipe is blocked or adequate ventilation is not possible, poisonous gases such as carbon monoxide (CO) may enter the vehicle. This is the case, e.g. if the vehicle becomes trapped in snow. There is a risk of fatal injury. If you leave the engine or the auxiliary heating running, make sure the exhaust pipe and area around the vehicle are clear of snow. To ensure an adequate supply of fresh air, open a window on the side of the vehicle that is not facing into the wind. Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Winter operation" section (Y page 328). Driving with summer tires Observe the notes in the "Winter operation" section (Y page 328). Slippery road surfaces G WARNING If you shift down on a slippery road surface in an attempt to increase the engine's braking effect, the drive wheels could lose their grip. There is an increased danger of skidding and accidents. Do not shift down for additional engine braking on a slippery road surface. 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. If the vehicle threatens to skid or cannot be stopped when moving at low speed: X Shift the transmission to position N. Drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking maneuvers. Do not use the cruise control or DISTRONIC PLUS. i For more information on driving with snow chains, see (Y page 329). Driving systems Cruise control 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 store any road speed above 20 mph (30 km/h). Cruise control lever Important safety notes 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. General 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, : To activate or increase speed ; To activate or reduce speed = To deactivate cruise control ?

Deactivating cruise control DISTRONIC PLUS Important safety notes 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 There are several ways to deactivate cruise control: X Briefly press the cruise control lever forwards :. or X Brake. 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 Z Driving and parking X 167 168 Driving systems could result in wrong or missing distance warnings. Driving and parking G WARNING DISTRONIC PLUS distance is not a substitute for the active intervention of the driver. It does not detect pedestrians or stationary objects, nor can it detect, recognize or predict the road's course or the movements of vehicles in front. DISTRONIC PLUS can only brake the vehicle using 40% of the vehicle's maximum available brake force. DISTRONIC PLUS may not detect narrow vehicles driving in front, e.g. motorcycles, or vehicles driving in the lane beyond the lane next to your vehicle, especially if the vehicles are not driving on the middle of their lane. The driver must always pay careful attention to the road, weather and traffic conditions. The driver must drive, steer and brake in a manner which will allow him to always have control of the vehicle. Sources of high-frequency radio waves, such as toll stations, speed-measuring radar, etc., can cause DISTRONIC PLUS to fail temporarily. 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. G WARNING 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. Driving systems 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 corresponds to approximately 40% of your vehicle's maximum braking force. To avoid a collision, you must apply the brakes yourself. DISTRONIC PLUS brakes the vehicle just enough to restore the preset speed or the preset distance to the vehicle in front. 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. General notes DISTRONIC PLUS regulates the speed and automatically helps you maintain the distance to the vehicle detected in front. DISTRONIC PLUS brakes automatically so that the set speed is not exceeded. If DISTRONIC PLUS detects a slower-moving vehicle in front, your vehicle is braked in order to maintain the preset distance to the vehicle in front. If you want DISTRONIC PLUS to assist you, the radar sensor system must be activated (Y page 223) and operational. If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control in the speed range between 20 mph (Canada: 30 km/h) and120 mph (Canada: 200 km/h). If a vehicle is driving in front of you, it operates in the speed range between 0 mph (0 km/h) and 120 mph (Canada: 200 km/h). Do not use DISTRONIC PLUS while driving on roads with steep gradients. As DISTRONIC PLUS transmits radar waves, it can resemble the radar detectors of the responsible authorities.

Therefore, the DISTRONIC PLUS distance display in the instrument cluster should be activated (Y page 217). 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 174). Pulling away and driving G WARNING When you step on the brake pedal, you switch off the DISTRONIC PLUS except when the vehicle is at a standstill. The DISTRONIC PLUS will no longer brake your vehicle. You are always responsible for maintaining a distance from other vehicles, observing road speeds and braking well in advance. 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 press it up : or down ;. or X Accelerate briefly. Your vehicle pulls away and adapts its speed to that of the vehicle in front. If there is no vehicle in front, DISTRONIC PLUS operates in the same way as cruise control. If DISTRONIC PLUS detects that the vehicle in front has slowed down, it brakes your vehicle. In this way, the distance you have selected is maintained. If DISTRONIC PLUS detects that the vehicle in front is driving faster, it accelerates your vehicle, but only up to the speed you have stored. Changing lanes 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.

Failure to observe these guidelines could cause the vehicle to skid. 4MATIC cannot prevent accidents resulting from excessive speed. ! Never tow the vehicle with one axle raised. This may damage the transfer case. Damage of this sort is not covered by the Mercedes-Benz Limited Warranty. All wheels must remain either on the ground or be fully raised. Observe the instructions for towing the vehicle with all wheels in full contact with the ground. i In wintry driving conditions, the maximum effect of 4MATIC can only be achieved if you use winter tires (M+S tires), with snow chains if necessary. 4MATIC ensures that all four wheels are permanently driven. Together with ESP®, it improves the traction of your vehicle whenever a drive wheel spins due to insufficient grip. PARKTRONIC Important safety notes G WARNING The PARKTRONIC is a supplemental system. It is not intended to, nor does it replace, the need for extreme care. The responsibility during parking and other critical maneuvers always remains with the driver. Z 183 Driving and parking Driving systems 184 Driving systems Driving and parking G WARNING Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured. PARKTRONIC is an electronic parking aid with ultrasonic sensors. It indicates visually and audibly the distance between your vehicle and an object. PARKTRONIC is activated automatically when you: Rswitch on the ignition Rshift the transmission to position D, R or N Rrelease the parking brake PARKTRONIC is deactivated at speeds above 11 mph (18km/h). It is reactivated at lower speeds. PARKTRONIC monitors the area around your vehicle using six sensors in the front bumper and four sensors in the rear bumper. : Example: sensors in the front bumper, left-hand side The sensors must be free of dirt, ice and slush. Otherwise, they may not function correctly. Clean the sensors regularly, taking care not to scratch or damage them (Y page 307). Range of the sensors General notes ! When parking, pay particular attention to objects above or below the sensors, such as flower pots or trailer drawbars. PARKTRONIC does not detect such objects when they are in the immediate vicinity of the vehicle. You could damage the vehicle or the objects. The sensors may not detect snow and other objects that absorb ultrasonic waves. Ultrasonic sources such as an automatic car wash, the compressed-air brakes on a truck or a pneumatic drill could cause PARKTRONIC to malfunction. PARKTRONIC may not function correctly on uneven terrain. Example: side view Example: top view Front sensors Center Approx. 40in (approx. 100cm) Corners Approx. 24in (approx. 60cm) Center Approx. 48in (approx. 120cm) Corners Approx. 32in (approx. 80cm) Rear sensors Minimum distance Center Approx. 8in (approx. 20cm) Corners Approx. 6in (approx. 15cm) If there is an obstacle within this range, the relevant warning displays light up and a warning tone sounds.

Active Parking Assist Important safety notes G WARNING Active Parking Assist is merely an aid and may sometimes recommend parking spaces that are not suitable for parking. For example, these might be spaces where parking is prohibited, driveways, unsuitable surfaces, etc. Active Parking Assist measures the parking space as you drive past it. Any later changes to the parking space are not taken into account. For instance, this may be the case when the vehicle parked in front of or behind the space changes its position or when an obstacle is moved into the parking space. Active Parking Assist does not relieve you of the responsibility of paying attention. If you rely solely on Active Parking Assist, you could cause an accident and injure yourself and others. You are always responsible for safety and must continue to pay attention to your immediate surroundings when parking and maneuvering. G WARNING Objects located above the height range of Active Parking Assist will not be detected when the parking space is measured. These are not taken into account when the parking procedure is calculated, e.g. overhanging loads, tail sections or loading ramps of goods vehicles. In some circumstances, Active Parking Assist may therefore guide you into the parking space too early. This may lead to a collision. For this reason, you should avoid using Active Parking Assist in such situations. Driving systems The front of the vehicle will veer out in the direction of the oncoming traffic during the parking operation. In some cases, the vehicle will also take you onto sections of the oncoming lane during the parking procedure. You are responsible for safety at all times and must pay attention to any road users approaching or passing. Stop the vehicle if necessary or cancel the Active Parking Assist parking procedure. G WARNING Make sure no persons or animals are in or near the area in which you are parking/ maneuvering. Otherwise, they could be injured. ! If unavoidable, you should drive over obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage the wheels or tires. Active Parking Assist is an electronic parking aid with ultrasound. Ultrasound is used to measure the road on both sides of the vehicle. A suitable parking space is indicated by the parking symbol. Active steering intervention can assist you during parking. You may also use PARKTRONIC (Y page 183). When PARKTRONIC is switched off, Active Parking Assist is also unavailable. Use Active Parking Assist for parking spaces: Rthat are parallel to the direction of travel are on straight roads, not bends Rthat are on the same level as the road, e.g. not on the pavement Parking tips: Rthat Rpay attention to the PARKTRONIC (Y page 185) warning messages during the parking procedure. Ryou can intervene in the steering procedure to correct it at any time. Active Parking Assist will then be canceled. Rwhen transporting a load which protrudes from your vehicle, you should not use Active Parking Assist. Rwhen snow chains or an emergency spare wheel are mounted, you should not use Active Parking Assist here either. Rmake sure that the tire pressures are always correct. This has a direct influence on the parking characteristics of the vehicle. Rthe way your vehicle is positioned in the parking space after parking is dependent on various factors. These include the position and shape of the vehicles parked in front and behind it and the conditions of the location. It may be the case that Active Parking Assist guides you too far into a parking space, or not far enough into it. In some cases, it may also lead you across or onto the curb. If necessary, you should abort the parking procedure with Active Parking Assist. Ryou can also engage forward gear prematurely. The vehicle redirects and does not drive as far into the parking space. Should the gear change occur too soon to achieve a sensible parking position, the parking procedure will be aborted. Ron narrow roads, drive past the parking space as close as possible. Rparking spaces that are littered, overgrown or partially occupied by trailer drawbars might be identified incorrectly or not at all. Rsnowfall or heavy rain may lead to a parking space being measured inaccurately. Z Driving and parking G WARNING 187 188 Driving systems Detecting a parking space Parking Driving and parking G WARNING Example: detected parking space : Detected parking space on the left ; Parking symbol = Detected parking space on the right Active Parking Assist is switched on automatically when driving forwards. The system is operational at speeds of up to approximately 22 mph (35 km/h). While in operation, the system independently locates and measures parking spaces on both sides of the vehicle. When driving at speeds below 19 mph (30 km/h), you will see the parking symbol as a status indicator in the instrument cluster. By default, Active Parking Assist only displays parking spaces on the frontpassenger side. Parking spaces on the driver's side are displayed as soon as the turn signal on the driver's side is activated. To park on the driver's side, you must leave the driver's side turn signal switched on. This must remain switched on until you acknowledge the use of Active Parking Assist by pressing the a button on the multifunction steering wheel.

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. General 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. 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 Z Driving and parking Guide lines in the COMAND display 191 192 Driving systems The functionality of ATTENTION ASSIST is restricted and warnings may be delayed or not occur at all: Driving and parking Rif the road condition is poor, e.g. if the surface is uneven or if there are potholes Rif there is a strong side wind Rif you have adopted a sporty driving style with high cornering speeds or high rates of acceleration Rif you are predominantly driving slower than 50 mph (80 km/h) or faster than 112 mph (180 km/h) Rif you are currently using COMAND or making a telephone call with it Rif the time has been set incorrectly Rin active driving situations, such as when you change lanes or change your speed Warning and display messages in the multifunction display If ATTENTION ASSIST is active, you will be warned no sooner than 20 minutes after your journey has begun. You then hear an intermittent warning tone twice and the Attention Assist: Drowsiness Detected message appears in the multifunction display. X Activate ATTENTION ASSIST using the onboard computer (Y page 218). Symbol : appears in the multifunction display. X If necessary, take a break. X Press the a button to confirm the message. On long journeys, take regular breaks in good time to allow yourself to rest properly. If you do not take a break, you will be warned again after 15 minutes at the earliest. The precondition for this is that ATTENTION ASSIST still detects typical indicators of fatigue or increasing lapses in concentration. ATTENTION ASSIST is reset when you continue your journey and starts assessing your tiredness again if: Ryou switch off the engine. take off your seat belt and open the driver's door, e.g. for a change of drivers or to take a break. Ryou Night View Assist Plus Important safety notes G WARNING Night View Assist Plus is only an aid designed to assist driving. It is not a substitute for attentive driving. Do not rely solely on the Night View Assist Plus display. Continue to look through the windshield. You are responsible for safety and must drive in accordance with traffic conditions. You could otherwise put yourself and others in danger. The system may be impaired or unavailable if: Rthere is poor visibility, e.g. due to snow, rain, fog or heavy spray. Rthe windshield is dirty, fogged up or covered, for instance by a sticker, in the vicinity of the camera. Ryou are driving on bends, uphill gradients or downhill gradients. G WARNING The Night View Assist Plus cannot record objects immediately in front of or next to the vehicle. When maneuvering, continue to look through the windshield. Make sure no persons or animals are in the area in which you are maneuvering. You could otherwise injure them. Driving systems 193 Rthe light switch is in the à or L position. Rreverse gear has not been engaged. In addition to the illumination provided by the normal headlamps, Night View Assist Plus uses infrared light to illuminate the road. Night View Assist Plus camera : picks up the infrared light and displays a monochrome image in COMAND. The image displayed in COMAND corresponds to a road lit up by highbeam headlamps. This enables you to see the road's course and any obstacles in good time. If pedestrian recognition is activated, pedestrians recognized by the system are highlighted in the Night View Assist Plus display. Light from the headlamps of oncoming vehicles does not affect the Night View Assist Plus display in the multifunction display. This is also the case if you cannot switch on the high-beam headlamps due to oncoming traffic. i Infrared light is not visible to the human eye and therefore does not glare. Night View Assist Plus can therefore remain switched on even if there is oncoming traffic. Switching on Night View Assist Plus Activation conditions You can only activate Night View Assist Plus if: Rthe SmartKey is in position 2 in the ignition X X Driving and parking Switching on Night View Assist Plus Make sure that COMAND is switched on. Press button :. The Night View Assist Plus display appears in the COMAND display.

Blind Spot Assist Important safety notes 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, 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. Z Driving and parking Problems with Night View Assist Plus Driving and parking 196 Driving systems General notes Blind Spot Assist uses a radar sensor system to monitor the areas on both sides of your vehicle. It supports you from 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. For Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 223) and operational. Monitoring range of the sensors 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. The Blind Spot Assist monitors the area up to 3.0 m behind your vehicle and directly next to your vehicle, as shown in the diagram. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles driving at the inner edge of their lanes. 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, for example lorries, for a prolonged time. The two radar 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 sensors must not be covered, for example by cycle racks or overhanging loads. Following a severe impact or in the event of damage to the bumpers, have the function of the sensors checked at a qualified specialist workshop. Blind Spot Assist may otherwise not work properly. Indicator and warning display G WARNING Blind Spot Assist is not active at speeds below approximately 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. Collision warning If a vehicle is detected in the monitoring range of Blind Spot Assist and you switch on the corresponding turn signal, a double warning tone sounds. Red warning lamp : flashes. If the turn signal remains on, detected vehicles are indicated by the flashing of red warning lamp :. There are no further warning tones. Switching on Blind Spot Assist X Make sure that the radar sensor system (Y page 223) and Blind Spot Assist (Y page 219) are activated in the on-board computer.

Lane Keeping Assist : Yellow indicator lamp/red warning lamp When Blind Spot Assist is activated, indicator lamp : in the exterior mirrors lights up yellow at speeds of up to 20 mph (30 km/h). At speeds above 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is operational. If a vehicle is detected within the monitoring range of Blind Spot Assist at speeds above 20 mph (30km/h), warning lamp : on the corresponding side lights up red. This warning is always emitted when a vehicle enters the blind spot monitoring range from behind or from the side. When you overtake a vehicle, the warning only occurs if the difference in speed is less than 7 mph (12km/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. Important safety notes G WARNING 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: Rthere is poor visibility, e.g. due to insufficient illumination of the road, or due to snow, rain, fog or spray. Rthere is glare, e.g. from oncoming traffic, the sun, or reflection from other vehicles. Rthe windshield is dirty, fogged up or covered, for instance by a sticker, in the vicinity of the camera. Rseveral or no lane markings for a single lane are present. 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.

General notes Active Blind Spot Assist uses a radar sensor system to monitor the side areas of your vehicle which are in back of the driver. A warning display in the exterior mirrors draws your attention to vehicles detected in the monitored area. If you then switch on the corresponding turn signal to change lane, you will also receive an optical and audible warning. If a risk of lateral collision is detected, corrective braking may help you Z 199 Driving and parking Driving systems Driving and parking 200 Driving systems avoid a collision. To support the coursecorrecting brake application, Active Blind Spot Assist uses the forward-facing radar sensor system. The free space in the direction of travel is then evaluated. Active Blind Spot Assist supports you from a speed of approximately 20 mph (30 km/h). For Active Blind Spot Assist to assist you when driving, the radar sensor system must be activated (Y page 223) and operational. Monitoring area G WARNING Active 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. No visual nor audible warnings are emitted and the system does not brake the vehicle to correct your course. 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. Active Blind Spot Assist monitors the area up to 10 ft (3.0m) behind your vehicle and directly next to your vehicle, as shown in the diagram. For this purpose, Active Blind Spot Assist uses radar sensors in the rear bumper. If the lanes are narrow, vehicles driving in the lane beyond the lane next to your vehicle may be indicated, especially if the vehicles are not driving in the middle of their lane. This may be the case if there are vehicles at the inner edge of your 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, for example lorries, for a prolonged time. The Active Blind Spot Assist radar sensors are integrated into the front and rear bumpers and behind a cover in the radiator grill. Make sure that the bumpers and the cover in the radiator grill are free of dirt, ice or slush. The rear sensors must not be covered, for example by cycle racks or overhanging cargo. Following a severe impact or in the event of damage to the bumpers, have the function of the radar sensors checked at a qualified specialist workshop. Active Blind Spot Assist may otherwise no longer work properly. Indicator and warning display G WARNING Active Blind Spot Assist is not active at speeds below 20 mph (30km/h).

This also applies to safetyrelated systems and functions. i Read the information on qualified specialist workshops: (Y page 24). Stowage areas Loading guidelines G WARNING Always fasten items being carried as securely as possible. Use cargo tie-down rings and fastening materials appropriate for the weight and size of the load. In an accident, during hard braking or sudden maneuvers, loose items will be thrown around inside the vehicle. This can cause injury to vehicle occupants unless the items are securely fastened in the vehicle. To help avoid personal injury during a collision or sudden maneuver, exercise care when transporting cargo. Do not pile luggage or cargo higher than the seat backrests. The trunk is the preferred place to carry objects. Never drive a vehicle with the trunk open. Deadly carbon monoxide (CO) gases may enter vehicle interior resulting in unconsciousness and death. The handling characteristics of a laden vehicle are dependent on the distribution of the load within the vehicle. For this reason, you should observe the following notes when transporting a load: Rwhen transporting a load, never exceed the maximum permissible gross vehicle weight or the gross axle weight rating of the vehicle (including occupants). The values are specified on the vehicle identification plate on the B-pillar of the driver's door. Rthe load must not protrude above the upper edge of the seat backrests. Ralways place the load against the rear or front seat backrests. Make sure that the seat backrests are securely locked into place. Ralways place the load behind unoccupied seats if possible.

Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safetyrelated systems and functions. i Read the information on qualified specialist workshops: (Y page 24). Wheels and tires Important safety notes G WARNING If wheels and tires of the wrong size are used, the wheel brakes or suspension components may be damaged. There is a risk of accident. Always replace wheels and tires with those that fulfill the specifications of the original part (designation, manufacturer, model). G WARNING A flat tire severely impairs the driving, steering and braking characteristics of the vehicle. There is a risk of accident. Tires without run-flat characteristics: Rdo not drive with a flat tire. replace the flat tire with your emergency spare wheel or spare wheel, or consult a qualified specialist workshop. Tires with run-flat characteristics: Rimmediately Rpay attention to the information and warning notices on MOExtended tires (tires with run-flat characteristics). Accessories that are not approved for your vehicle by Mercedes-Benz or are not being used correctly can impair the operating safety. Before purchasing and using non-approved accessories, visit a qualified specialist workshop and inquire about: Rsuitability Rlegal stipulations recommendations Information on the dimensions and types of wheels and tires for your vehicle can be found under "Wheel/tire combinations" (Y page 353). Information on air pressure for the tires on your vehicle can be found: Rfactory Ron the vehicle's Tire and Loading Information placard on the B-pillar (Y page 337) Ron the tire pressure label on the fuel filler flap (Y page 155) Runder "Tire pressure" (Y page 329) Rin the "Tire pressure" section Operation Information on driving If the vehicle is heavily laden, check the tire pressures and correct them if necessary. While driving, pay attention to vibrations, noises and unusual handling characteristics, e.g. pulling to one side. This may indicate that the wheels or tires are damaged. If you suspect that a tire is defective, reduce your speed immediately. Stop the vehicle as soon as possible to check the wheels and tires for damage. Hidden tire damage could also be causing the unusual handling characteristics. If you find no signs of damage, have the tires and wheels checked at a qualified specialist workshop. When parking your vehicle, make sure that the tires do not get deformed by the curb or other obstacles. If it is necessary to drive over curbs, speed humps or similar elevations, try to do so slowly and at an obtuse angle. Otherwise, the tires, particularly the sidewalls, may be damaged. Operation Regular checking of wheels and tires Tire tread G WARNING G WARNING Regularly check the wheels and tires of your vehicle for damage at least once a month, as well as after driving off-road or on rough roads. Damaged wheels can cause a loss of tire pressure. Pay particular attention to damage such as: Rcuts in the tires Rpunctures Rtears in the tires Rbulges on tires Rdeformation or severe corrosion on wheels Regularly check the tire tread depth and the condition of the tread across the whole width of the tire (Y page 327). If necessary, turn the front wheels to full lock in order to inspect the inner side of the tire surface. All wheels must have a valve cap to protect the valve against dirt and moisture. Do not mount anything onto the valve other than the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle. Do not use any other valve caps or systems, e.g. tire pressure monitoring systems. Regularly check the pressure of all the tires particularly prior to long trips. Adjust the tire pressure as necessary (Y page 329). Observe the notes on the emergency spare wheel (Y page 357). The service life of tires depends on the following factors amongst other things: RDriving style pressure RDistance covered Insufficient tire tread will reduce tire traction. The tire is no longer able to dissipate water. This means that on wet road surfaces, the risk of hydroplaning increases, in particular where speed is not adapted to suit the driving conditions. There is a risk of accident. If the tire pressure is too high or too low, tires may exhibit different levels of wear at different locations on the tire tread. Thus, you should regularly check the tread depth and the condition of the tread across the entire width of all tires. Minimum tire tread depth for: RSummer RM+S tires: â in (3 mm) tires: ã in (4 mm) For safety reasons, replace the tires before the legally prescribed limit for the minimum tire tread depth is reached. Bar indicator : for tread wear is integrated into the tire tread. Tread wear indicators (TWI) are required by law. Six indicators are positioned on the tire tread. They are visible once the tread depth is approximately á in (1.6 mm). If this is the case, the tire is so worn that it must be replaced. RTire Z Wheels and tires Damaged tires can cause tire inflation pressure loss. As a result, you could lose control of your vehicle. There is a risk of accident. Check the tires regularly for signs of damage and replace any damaged tires immediately. 327 328 Winter operation Selecting, mounting and replacing tires mount tires and wheels of the same type and make. ROnly mount tires of the correct size onto the wheels. RBreak in new tires at moderate speeds for the first 60 miles (100 km). They only reach their full performance after this distance. RDo not drive with tires which have too little tread depth, as this significantly reduces the traction on wet roads (hydroplaning). RReplace the tires after six years at the latest, regardless of wear. Observe the notes on the emergency spare wheel (Y page 357). Wheels and tires ROnly MOExtended tires (tires with run-flat properties) With MOExtended tires (tires with run flat characteristics), you can continue to drive your vehicle even if there is a total loss of pressure in one or more tires. MOExtended tires may only be used in conjunction with an active tire pressure loss warning system or with an active tire pressure monitor and on wheels specifically tested by Mercedes-Benz. Notes on driving with MOExtended tires with a flat tire (Y page 313). i Vehicles equipped with MOExtended tires are not equipped with a TIREFIT kit at the factory. It is therefore recommended that you additionally equip your vehicle with a TIREFIT kit if you mount tires that do not feature run-flat properties, e.g. winter tires. A TIREFIT kit can be obtained from a qualified specialist workshop. Winter operation General notes Have your vehicle winterproofed at a qualified specialist workshop at the onset of winter. Observe the notes in the "Changing a wheel" section (Y page 348). Driving with summer tires At temperatures below 45 ‡ (+7 †), summer tires lose elasticity significantly, and therefore traction and braking power as well. Change the tires on your vehicle to M+S tires. Using summer tires at very cold temperatures could cause cracks to form, thereby damaging the tires permanently. Mercedes-Benz cannot accept responsibility for this type of damage. M+S tires G WARNING M+S tires with a tire tread depth of less than ã in (4 mm) are not suitable for use in winter and do not provide sufficient traction. There is a risk of an accident. M+S tires with a tread depth of less than ã in (4 mm) must be replaced immediately. At temperatures below 45 ‡ (+7 †), use winter tires or all-weather 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. Tire pressure X Check the tire pressures (Y page 333). Vehicles for Canada: restart the tire pressure loss warning system (Y page 333). X Restart the tire pressure monitor (Y page 334). X For more information on driving with the emergency spare wheel, see (Y page 357). Snow chains G WARNING If snow chains are installed to the front wheels, they may drag against the vehicle body or chassis components. This could cause damage to the vehicle or the tires. There is a risk of an accident. To avoid hazardous situations: Rnever install snow chains to the front wheels Ralways install snow chains in pairs to the rear wheels. ! On vehicles with AIRMATIC, you must drive at raised vehicle level if snow chains have been mounted. The vehicle may otherwise be damaged. ! On some tire sizes there is not enough space for snow chains. To avoid damage to the vehicle or tires, observe the "Wheel and tire combinations" section under "Tires and wheels". For safety reasons, Mercedes-Benz recommends that you only use snow chains that have been specially approved for your vehicle by Mercedes-Benz, or are of a corresponding standard of quality. If you intend to mount snow chains, please bear the following points in mind: RSnow chains may not be mounted on all wheel/tire combinations. Permissible wheel-tire combinations (Y page 353). ROnly use snow chains when driving on roads completely covered by snow. Remove the snow chains as soon as possible when you come to a road that is not snow-covered. RLocal regulations may restrict the use of snow chains. Observe the appropriate regulations if you wish to mount snow chains. RDo not exceed the maximum permissible speed of 30 mph (50 km/h). i You may wish to deactivate ESP® when pulling away with snow chains installed (Y page 67). This way you can allow the wheels to spin in a controlled manner, achieving an increased driving force (cutting action). For more information on driving with the emergency spare wheel, see (Y page 357). Tire pressure Tire pressure specifications Important safety notes G WARNING Tires with tire pressures that are too low or too high are associated with the following hazards: Rthey can burst, in particular if the vehicle is heavily laden or when driven at high speeds. Rthe tires can wear excessively and/or unevenly, which can severely impair tire traction. Rthe driving, steering and braking characteristics may be severely impaired. There is a risk of accident. Z Wheels and tires Always observe the maximum permissible speed specified for the M+S tires you have mounted. Once the winter tires are mounted: 329 330 Tire pressure Follow recommended tire inflation pressures and check the pressure of all the tires including the spare wheel: Rmonthly, at least the load changes Rbefore beginning a long journey Runder different operating conditions, e.g. off-road driving If necessary, correct the tire pressure. Rif The Tire and Loading Information placard contains the recommended tire pressures for cold tires. The recommended tire pressures are valid for the maximum permissible load and up to the maximum permissible vehicle speed. Tire pressure table The tire pressure table is on the inside of the fuel filler flap. Wheels and tires i The specifications on the sample Tire and Loading Information placard and tire pressure tables are examples. Tire pressure specifications are vehicle-specific and may deviate from the data shown here. The tire pressure specifications that are valid for your vehicle can be found on the Tire and Loading Information placard and tire pressure table on the vehicle. General notes The recommended tire pressures for the tires mounted at the factory can be found on the labels described here. Operation with the emergency spare wheel (Y page 357). Further information on tire pressures can be obtained at a qualified specialist workshop. Example: tire pressure table for all tires permitted for this vehicle by the factory The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. Tire and Loading Information placard Example: tire pressure table with tire dimensions : Recommended tire pressures The Tire and Loading Information placard is on the B-pillar on the driver's side (Y page 337). If a tire size precedes a tire pressure, the tire pressure information following is only valid for that tire size. The load conditions "partially laden" and "fully laden" are defined in the table for different numbers of occupants and amounts of luggage. The actual number of seats may differ. Tire pressure 331 If you are unable to rectify the damage, contact a qualified specialist workshop. G WARNING Rif you want to drive with an increased load and/or Rif you want to drive at higher road speeds. i The tire pressures for increased loads and/or higher road speeds, shown in the tire pressure table, may have a negative effect on driving comfort. If the tire pressure is not set correctly, this can lead to an excessive build up of heat and a sudden loss of pressure. For more information, contact a qualified specialist workshop. Important notes on tire pressure G WARNING If the tire pressure drops repeatedly, the wheel, valve or tire may be damaged. Tire pressure that is too low may result in a tire blow-out. There is a risk of an accident. RCheck the tire for foreign objects. RCheck whether the wheel is losing air or the valve is leaking. Use a suitable pressure gauge to check the tire pressure. The outer appearance of a tire does not permit any reliable conclusion about the tire pressure. On vehicles equipped with the electronic tire pressure monitoring system, the tire pressure can be checked using the on-board computer. The tire temperature and pressure increase when the vehicle is in motion. This is dependent on the driving speed and the load. Therefore, you should only correct tire pressures when the tires are cold. The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has been driven for less than 1 mile (1.6 km). The tire temperature changes depending on the outside temperature, the vehicle speed and the tire load. If the tire temperature changes by 18 ‡ (10 †), the tire pressure changes by approximately 10 kPa (0.1 bar/ 1.5 psi). Take this into account when checking the pressure of warm tires. Only correct the tire pressure if it is too low for the current operating conditions. If you check the tire pressure when the tires are warm, the resulting value will be higher than if the tires were cold. This is normal. Do not reduce the tire pressure to the value specified for cold Z Wheels and tires 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 342). 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: If you fit unsuitable accessories onto tire valves, the tire valves may be overloaded and malfunction, which can cause tire pressure loss. Due to their design, retrofitted tire pressure monitors keep the tire valve open. This can also result in tire pressure loss. There is a risk of an accident. Only screw the standard valve cap or other valve caps approved by Mercedes-Benz for your vehicle onto the tire valve. 332 Tire pressure tires. The tire pressure would otherwise be too low. Observe the recommended tire pressures for cold tires: Ron the Tire and Loading Information placard on the B-pillar on the driver's side the tire pressure table on the inside of the fuel filler flap Ron the yellow label on the emergency spare wheel (depending on the vehicle equipment) Rin Overinflated tires may: Rincrease the braking distance an adverse effect on handling characteristics Rwear quickly and unevenly Rhave an adverse effect on ride comfort Rbe more susceptible to damage Rhave Maximum tire pressures Underinflated or overinflated tires Underinflation Wheels and tires G WARNING Tires with pressure that is too low can overheat and burst as a consequence. In addition, they also suffer from excessive and/ or irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too low in all the tires, including the spare wheel. Underinflated tires may: Roverheat, leading to tire defects an adverse effect on handling characteristics Rwear quickly and unevenly Rhave an adverse effect on fuel consumption Rhave Overinflation G WARNING Tires with excessively high pressure can burst because they are damaged more easily by road debris, potholes etc. In addition, they also suffer from irregular wear, which can severely impair the braking properties and the driving characteristics. There is a risk of an accident. Avoid tire pressures that are too high in all the tires, including the spare wheel. : Example: maximum permissible tire pressure Never exceed the maximum permissible tire inflation pressure. Always observe the recommended tire pressure for your vehicle when adjusting the tire pressure (Y page 329). i The actual values for tires are vehiclespecific and may deviate from the values in the illustration. Checking the tire pressures Important safety notes Observe the notes on tire pressure (Y page 329). Information on air pressure for the tires on your vehicle can be found: Ron the vehicle's Tire and Loading Information placard on the B-pillar (Y page 337) Ron the tire pressure label on the fuel filler flap (Y page 155) Tire pressure the "Tire pressure" section "Tire pressure" (Y page 329) Runder Checking tire pressures 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 (Y page 329). X If the tire pressure is too low, increase it to the recommended value. X If the tire pressure is too high, release air by pressing down the metal pin in the valve. Use the tip of a pen, for example. Then, check the tire pressure again using the tire pressure gauge. X Screw the valve cap onto the valve. X Repeat these steps for the other tires. 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. The tire pressure warning system does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 329). The tire pressure loss warning system does not replace the need to regularly check your vehicle's tire pressures, since an even loss of pressure on several tires at the same time cannot be detected by the tire pressure loss warning system. The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid 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 the wheels or tires Rmounted new wheels or tires X Before restarting, make sure that the tire pressures are set properly on all four tires for the respective operating conditions. The recommended tire pressures can be found on the Tire and Loading Information placard on the B-pillar on the driver's side or the tire pressure table on the fuel filler flap. 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.

Tire pressure monitor Important safety notes G WARNING Each tire, including the spare (if provided), should be checked at least once a month when cold and inflated to the pressure recommended by the vehicle manufacturer on the Tire and Loading Information placard on the driver's door B-pillar or the tire pressure label on the inside of the fuel filler flap. If your vehicle has tires of a different size than the size indicated on the Tire and Loading Information placard or the tire pressure label, you should determine the proper tire pressure for those tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. Underinflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to maintain correct tire 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 if the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, the warning lamp will flash for approximately a minute and then remain continuously illuminated. This sequence will be repeated every time the vehicle is started as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to continue to function properly. It is the driver's responsibility to set the tire pressure to that recommended for cold tires which is suitable for the operating situation (Y page 329). Note that the correct tire pressure for the current operating situation must first be taught-in to the tire pressure monitor. If there is a substantial loss of pressure, the warning threshold for the warning message is aligned to the reference values taught-in. Restart the tire pressure monitor after adjusting the pressure of the cold tires (Y page 336). The current pressures are saved as new reference values. As a result, a warning message will appear if the tire pressure drops significantly. The tire pressure monitor does not warn you of an incorrectly set tire pressure. Observe the notes on the recommended tire pressure (Y page 329). The tire pressure monitor is not able to warn you of a sudden loss of pressure, e.g. if the tire is penetrated by a foreign object. In the event of a sudden loss of pressure, bring the vehicle to a halt by braking carefully. Avoid abrupt steering maneuvers. If a tire pressure monitor system is installed, the vehicle's wheels have sensors installed that monitor the tire pressures in all four tires. The tire pressure monitor warns you if the pressure drops in one or more of the tires. The tire pressure monitor only functions if the correct sensors are installed on all wheels. 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 monitor is malfunctioning: Rif the warning lamp is lit continuously, the tire pressure on one or more tires is significantly too low. The tire pressure monitor is not malfunctioning. RUSA only: if the warning lamp flashes for around a minute and then remains lit constantly, the tire pressure monitor is malfunctioning. 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. USA only: if there is a malfunction with the tire pressure monitor it can take more than ten minutes until the malfunction is shown by the tire pressure warning lamp flashing for approximately one minute and then lighting up continuously. When the malfunction has been rectified, the tire pressure warning lamp goes out after a few minutes of driving. The tire pressure values indicated by the onboard computer may differ from those measured at a gas station with a pressure gauge. The tire pressures shown by the onboard computer refer to those measured at sea level. At high altitudes, the tire pressure values indicated by a pressure gauge are higher than those shown by the on-board computer. In this case, do not reduce the tire pressures. The operation of the tire pressure monitor can be affected by interference from radio transmitting equipment (e.g. radio headphones, two-way radios) that may be being operated in or near the vehicle. i USA only: This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: 1.

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 an 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 wheel is mounted is not the same as the current tire pressure of the emergency spare wheel. Tire pressure monitor warning messages If the tire pressure monitor detects a significant pressure loss on one or more tires, a warning message is shown in the multifunction display. A warning tone also sounds and the tire pressure warning lamp lights up in the instrument cluster. Each tire that is affected by a significant loss of pressure is highlighted in the pressure display. X If the Correct Tire Pressure message appears in the multifunction display, check the tire pressure on all four wheels and correct it if necessary. 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 When you restart the tire pressure monitor, all existing warning messages are deleted and the warning lamps go out. The monitor uses the currently set tire pressures as the reference values for monitoring. In most cases, the tire pressure monitor will automatically detect the new reference values after you have changed the tire pressure. However, you can also define reference values manually as described here. The tire pressure monitor then monitors the new tire pressure values.

Number of seats Maximum number of seats : indicates the maximum number of occupants allowed to 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. X Step 4: The resulting figure equals the available amount of cargo and luggage load capacity. For example: at a sum “XXX” of 1400 lbs and five occupants each weighing 150 lbs, 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. Loading the vehicle The following table shows examples on how to calculate total and cargo load capacities with varying seating configurations and number and size of occupants. The following examples use a load limit of 1500 lbs (680 kg). This is for illustration purposes only. Make sure you are using the actual load limit for your vehicle stated on your vehicle's Tire and Loading Information placard (Y page 337).

All about wheels and tires Uniform Tire Quality Grading Standards Overview of Tire Quality Grading Standards Uniform Tire Quality Grading Standards are U.S. government specifications. Their purpose is to provide drivers with uniform reliable information on tire performance data. Tire manufacturers have to grade tires using three performance factors: : tread wear grade, ; traction grade and = temperature grade. These regulations do not apply to Canada. Nevertheless, all tires sold in North America are provided with the corresponding quality grading markings on the sidewall of the tire. Where applicable, the tire grading information can be found on the tire sidewall between the tread shoulder and maximum tire width. Example: RTreadwear grade: 200 grade: AA RTemperature grade: A RTraction All about wheels and tires i The actual values for tires are vehiclespecific and may deviate from the values in the illustration. Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified U.S. government course. For example, a tire graded 150 would wear one and one-half times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm, due to variations in driving habits, service practices and differences in road characteristics and climate conditions. Traction G WARNING The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics. ! Avoid wheelspin. This can lead to damage to the drive train. The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire's ability to stop on a wet surface as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. The safe speed on a wet, snow covered or icy road is always lower than on dry road surfaces. You should pay special attention to road conditions when temperatures are around freezing point. Mercedes-Benz recommends a minimum tread depth of ã in (4 mm) on all four winter tires. Observe the legally required minimum tire tread depth (Y page 327). Winter tires can reduce the braking distance on snow-covered surfaces in comparison with summer tires. The braking distance is still much further than on surfaces that are not icy or covered with snow. Take appropriate care when driving. Further information on winter tires (M+S tires) (Y page 328). Temperature G WARNING The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause excessive heat build-up and possible tire failure. The temperature grades are A (the highest), B, and C. These represent the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

Drive carefully and adapt your driving style to the traffic conditions. Summer tires Index Speed rating Q up to 100 mph (160 km/h) R up to 106 mph (170 km/h) Index Speed rating S up to 112 mph (180 km/h) T up to 118mph (190 km/h) H up to 130mph (210 km/h) V up to 149 mph (240 km/h) W up to 168 mph (270 km/h) Y up to 186mph (300 km/h) ZR...Y up to 186mph (300 km/h) ZR...(..Y) over 186 mph (300 km/h) ZR over 149 mph (240 km/h) ROptionally, tires with a maximum speed of over 149 mph (240 km/h) may have a “ZR” in the size description, depending on the manufacturer (e.g. 245/40 ZR18). The service specification is made up of load-bearing index A and speed rating B. RIf the size description of your tire includes "ZR" and there are no service specifications, ask the tire manufacturer in order to find out the maximum speed. If a service specification is available, the maximum speed is limited according to the speed rating in the service specification. Example: 245/40 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 (300km/h). REvery tire that has a maximum speed of more than 186 mph (300 km/h) must have a "ZR" in the size description and the service specification must be given in parentheses. Example: 275/40 ZR 18 (99 Y). The speed rating "(Y)" indicates that the maximum speed of the tire is over 186 mph (300 km/h). Ask the tire manufacturer about the maximum speed. Z Wheels and tires ratio is calculated by dividing the tire width by the tire height. Tire code: tire code = specifies the tire type. "R" represents radial tires; "D" represents diagonal tires; "B" represents diagonal radial tires. Optionally, tires with a maximum speed of over 149 mph (240 km/h) may have a “ZR” in the size description, depending on the manufacturer (e.g. 245/40 ZR 18). Rim diameter: rim diameter ? is the diameter of the bead seat, not the diameter of the rim flange. The rim diameter is specified in inches (in). Load-bearing index: load-bearing index A is a numerical code that specifies the maximum load-bearing capacity of a tire. Do not overload the tires by exceeding the specified load limit. The maximum permissible load can be found on the vehicle's Tire and Loading Information placard on the B-pillar on the driver's side (Y page 337). Example: The load bearing index 91 is equivalent to a maximum load of 1356 lb (615 kg) that the tire can carry. For further information on the maximum tire load in kilograms and lbs, see (Y page 344). For further information on the load bearing index, see "Load index" (Y page 344). Speed rating: speed rating B specifies the approved maximum speed of the tire. 343 All about wheels and tires 344 All-weather tires and winter tires Index Speed rating Q M+S3 up to 100 mph (160 km/h) T M+S3 up to 118mph (190 km/h) H M+S3 up to 130mph (210 km/h) V M+S3 up to 149 mph (240 km/h) Load index Wheels and tires i Not all tires with the M+S marking provide the driving characteristics of winter tires. In addition to the M+S marking, winter tires also have the i snowflake symbol on the tire wall. Tires with this marking fulfill the requirements of the Rubber Manufacturers Association (RMA) and the Rubber Association of Canada (RAC) regarding the tire traction on snow. They have been especially developed for driving on snow. An electronic speed limiter prevents your vehicle from exceeding the following speeds: Rall vehicles (except AMG vehicles): 130 mph (210 km/h) RAMG vehicles: 155 mph (250 km/h) RAMG vehicles with Performance Package: 186 mph (300 km/h) i Tire data is vehicle-specific and may deviate from the data in the example. Maximum load rating R The speed rating of tires mounted at the factory may be higher than the maximum speed that the electronic speed limiter permits. Make sure that your tires have the required speed rating, e.g. when buying new tires. The required speed rating for your vehicle can be found in the "Tires" section (Y page 353). Further information about reading tire data can be obtained from any qualified specialist workshop. 3 In addition to the load bearing index, load index : may be imprinted after the letters that identify speed index B on the sidewall of the tire (Y page 342). RIf no specification is given: no text (as in the example above), represents a standard load (SL) tire RXL or Extra Load: represents a reinforced tire RLight Load: represents a light load tire RC, D, E: represents a load range that depends on the maximum load that the tire can carry at a certain pressure Or M+Si for winter tires. Maximum tire load : is the maximum permissible weight for which the tire is approved. All about wheels and tires Do not overload the tires by exceeding the specified load limit. The maximum permissible load can be found on the vehicle's Tire and Loading Information placard on the B-pillar on the driver's side (Y page 337). i The actual values for tires are vehiclespecific and may deviate from the values in the illustration. DOT, Tire Identification Number (TIN) U.S. tire regulations prescribe that every tire manufacturer or retreader must imprint a TIN in or on the sidewall of every tire produced. 345 Tire size: identifier = describes the tire size. Tire type code: tire type code ? can be used by the manufacturer as a code to describe specific characteristics of the tire. Date of manufacture: date of manufacture A provides information about the age of a tire. The first and second positions represent the week of manufacture, starting with "01" for the first calendar week. Positions three and four represent the year of manufacture. For example, a tire that is marked with "3208", was manufactured in week 32 in 2008. i Tire data is vehicle-specific and may deviate from the data in the example. The TIN is a unique identification number. The TIN enables the tire manufacturers or retreaders to inform purchasers of recalls and other safety-relevant matters. It makes it possible for the purchaser to easily identify the affected tires. The TIN is made up of manufacturer identification code ;, tire size =, tire type code ? and manufacturing date A. DOT (Department of Transportation): tire symbol : indicates that the tire complies with the requirements of the U.S. Department of Transportation. Manufacturer identification code: manufacturer identification code ; provides details on the tire manufacturer. New tires have a code with two symbols. Retreaded tires have a code with four symbols. For further information about retreaded tires, see (Y page 326).

DOT (Department of Transportation) DOT marked tires fulfill the requirements of the United States Department of Transportation. Speed rating The speed rating is part of the tire identification. It specifies the speed range for which the tire is approved. Normal occupant weight The number of occupants for which the vehicle is designed multiplied by 68 kilograms (150 lb). GVW (Gross Vehicle Weight) The gross vehicle weight includes the weight of the vehicle including fuel, tools, the spare wheel, accessories installed, occupants, luggage and the drawbar noseweight, if applicable. The gross vehicle weight must not exceed the gross vehicle weight rating GVWR as specified on the vehicle identification plate on the B-pillar on the driver's side. Uniform Tire Quality Grading Standards A uniform standard to grade the quality of tires with regards to tread quality, tire traction and temperature characteristics. Ratings are determined by tire manufacturers using U.S. government testing procedures. The ratings are molded into the sidewall of the tire. Recommended tire pressure The recommended tire pressure applies to the tires mounted at the factory. The Tire and Loading Information placard contains the recommended tire pressures for cold tires on a fully loaded vehicle and for the maximum permissible vehicle speed. The tire pressure table contains the recommended pressures for cold tires for various operating conditions, i.e. differing load and speed conditions. Increased vehicle weight due to optional equipment This is the combined weight of all standard and optional equipment available for the vehicle, regardless of whether it is actually installed on the vehicle or not. Rim This is the part of the wheel on which the tire is mounted. GAWR (Gross Axle Weight Rating) The GAWR is the maximum gross axle weight rating. The actual load on an axle must never exceed the gross axle weight rating. The gross axle weight rating can be found on the GVWR (Gross Vehicle Weight Rating) The GVWR is the maximum permissible gross weight of a fully loaded vehicle (the weight of the vehicle including all accessories, occupants, fuel, luggage and the drawbar noseweight, if applicable). The gross vehicle weight rating is specified on the vehicle identification plate on the B-pillar on the driver's side. Maximum loaded vehicle weight The maximum weight is the sum of: Rthe curb weight of the vehicle weight of the accessories Rthe load limit Rthe weight of the factory installed optional equipment Rthe Kilopascal (kPa) Metric unit for tire pressure. 6.9 kPa corresponds to 1 psi. Another unit for tire pressure is bar. 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. All about wheels and tires Maximum load rating The maximum tire load is the maximum permissible weight in kilograms or lbs 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. Tire pressure This is pressure inside the tire applying an outward force to each square inch of the tire's surface. The tire pressure is specified in pounds per square inch (psi), in kilopascal (kPa) or in bar. The tire pressure should only be corrected when the tires are cold. Cold tire pressure The tires are cold: Rif the vehicle has been parked without direct sunlight on the tires for at least three hours and Rif the vehicle has been driven for less than 1 mile (1.6 km). Tread The part of the tire that comes into contact with the road. Bead The tire bead ensures that the tire sits securely on the wheel. There are several steel wires in the bead to prevent the tire from coming loose from the wheel rim. Sidewall The part of the tire between the tread and the bead. Weight of optional extras The combined weight of those optional extras that weigh more than the replaced standard parts and more than 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 the weight of the accessories. TIN (Tire Identification Number) This is a unique identifier which can be used by a tire manufacturer to identify tires, for example for a product recall, and thus identify the purchasers. The TIN is made up of the manufacturer's identity code, tire size, tire type code and the manufacturing date. Load bearing index The load bearing index (also load index) is a code that contains the maximum load bearing capacity of a tire. Traction Traction is the result of friction between the tires and the road surface. Treadwear indicators Narrow bars (tread wear bars) that are distributed over the tire tread. If the tire tread is level with the bars, the wear limit of á in (1.6 mm) has been reached. Z Wheels and tires Curb weight The weight of a vehicle with standard equipment including the maximum capacity of fuel, oil and coolant. It also includes the airconditioning system and optional equipment if these are installed in the vehicle, but does not include passengers or luggage. 347 348 Changing a wheel Occupant distribution The distribution of occupants in a vehicle at their designated seating positions. Total load limit Rated cargo and luggage load plus 68 kilograms (150 lb) multiplied by the number of seats in the vehicle. Changing a wheel Wheels and tires Flat tire You can find information on what to do in the event of a flat tire in the "Breakdown assistance" section (Y page 313). Instructions for driving with MOExtended tires in the event of a flat tire are also provided there. The "Breakdown assistance" section (Y page 313) contains information and notes on how to deal with a flat tire. Instructions for driving with MOExtended tires in the event of a flat tire are also provided there. Interchanging the wheels G WARNING Interchanging the front and rear wheels may severely impair the driving characteristics if the wheels or tires have different dimensions. The wheel brakes or suspension components may also be damaged. There is a risk of accident. Rotate front and rear wheels only if the wheels and tires are of the same dimensions. ! On vehicles equipped with a tire pressure monitor, electronic components are located in the wheel. Tire-mounting tools should not be used near the valve. This could damage the electronic components. Only have tires changed at a qualified specialist workshop. Always observe the instructions and safety notes in the "Mounting a wheel" section (Y page 349). 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 3,000 to 6,000 miles (5,000 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 pressure and, if necessary, restart the tire pressure loss warning system or the tire pressure monitor. Direction of rotation Tires with a specified direction of rotation have additional benefits, e.g. if there is a risk of hydroplaning. You will only gain these benefits if the correct direction of rotation is maintained. An arrow on the sidewall of the tire indicates its correct direction of rotation. Storing wheels Store wheels that are not being used in a cool, dry and preferably dark place. Protect the tires from oil, grease, gasoline and diesel. Cleaning the wheels G WARNING The water jet from a circular jet nozzle (dirt blasters) can cause invisible exterior damage Changing a wheel to the tires or chassis components. Components damaged in this way may fail unexpectedly. There is a risk of an accident. Do not use power washers with circular jet nozzles to clean the vehicle. Have damaged tires or chassis components replaced immediately. 349 Securing the vehicle to prevent it from rolling away Mounting a wheel X Park the vehicle on firm, non-slippery and level ground.

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) = 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. RMO1 Information on tires, wheels and approved combinations can be obtained from any qualified specialist workshop.

Do not use diesel to refuel vehicles with a gasoline engine. Even small amounts of the wrong fuel result in damage to the fuel system and engine. ! You should only refuel with unleaded premium-grade gasoline as this avoids damaging the catalytic converter. If engine running problems are apparent, have the cause checked immediately and repaired. Excess unburned fuel can otherwise enter the catalytic converter, leading to overheating and possibly causing a fire. ! 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 unleaded gasoline must be used, please observe the following precautions: Ronly fill the fuel tank to half full with regular 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 3000 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. Only refuel using premium-grade unleaded gasoline with a minimum octane rating of 91. Reformulated Gasoline (RFG) and/or unleaded gasoline with additives can be used. The concentration of additives in the fuel, however, must not exceed 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, may be used. Z Technical data 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. 367 368 Service products and filling capacities All of these mix fuels must fulfill the fuel requirements, e.g.: Rknock resistance point Rvapor pressure You will usually find information about the fuel grade on the pump. If you cannot find the label on the pump, ask the staff for assistance. Rboiling i For further information, consult an authorized Mercedes-Benz Center or on the Internet at http://www.mbusa.com (USA only). Information on refueling (Y page 155). Technical data Additives ! 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. 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 branded fuels that have additives. If you use fuels without these additives over a longer period of time, carbon deposits may build up. These deposits form at the inlet valves and in the combustion chamber in particular. 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 additives approved for use in Mercedes-Benz vehicles; see http://bevo.mercedes-benz.com. Runeven For a list of approved products, consult an authorized Mercedes-Benz Center. 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. Engine oil General notes ! 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. The engine oils are matched to the performance of Mercedes-Benz engines and service intervals. You should therefore only use engine oils and oil filters that are approved for vehicles with maintenance systems. For a list of approved engine oils and oil filters, consult an authorized Mercedes-Benz Center. Or visit the website http://bevo.mercedes-benz.com.

This could damage the engine. Engine oil viscosity 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 Maintenance Booklet. Only use brake fluid approved by MercedesBenz according to MB Approval 331.0. Information about approved brake fluid can be obtained at any qualified specialist workshop or on the Internet at http://bevo.mercedes-benz.com. i Have the brake fluid renewed regularly at a qualified specialist workshop. Coolant Important safety notes 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 table shows you which SAE classifications are 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 G WARNING Antifreeze is highly flammable. Fire, open flames and smoking are prohibited when handling antifreeze. If antifreeze comes into contact with hot engine parts, it may ignite and you could burn yourself. Do not spill any antifreeze on hot engine parts. ! Only add coolant that has been premixed with the desired antifreeze protection. You could otherwise damage the engine. Z Technical data Filling capacities 370 Service products and filling capacities Further information on coolants can be found in the Mercedes-Benz Specifications for Service Products, MB Specifications for Service Products 310.1, e.g. on the Internet at http://bevo.mercedes-benz.com. Or contact a qualified specialist workshop. ! 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. The coolant is a mixture of water and antifreeze/corrosion inhibitor. It performs the following tasks: Technical data Rcorrosion protection Rantifreeze protection Rraising the boiling point If the coolant has antifreeze protection down to -35 ‡ (-37 †), the boiling point of the coolant during operation is approximately 266 ‡ (130 †). The antifreeze/corrosion inhibitor concentration in the engine cooling system should: Rbe at least 50%. This will protect the engine cooling system against freezing down to approximately -35 ‡ (-37 †). Rnot exceed 55% (antifreeze protection down to -49 ‡ [-45 †]). Otherwise, heat will not be dissipated as effectively. If the vehicle has lost coolant, add equal amounts of water and antifreeze/corrosion inhibitor. Mercedes-Benz recommends an antifreeze/corrosion inhibitor concentrate in accordance with MB Specifications for Service Products 310.1. The coolant is checked with every maintenance interval at a qualified specialist workshop. i When the vehicle is first delivered, it is filled with a coolant mixture that ensures adequate antifreeze and corrosion protection.
