Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety- related systems and functions. i Please read the information on qualified specialist workshops (Y page 29). Occupant safety Overview of occupant safety In this section, you will learn the most important facts about the restraint system components of the vehicle. The restraint system consists of: Rseat belts Rchild restraint systems RLATCH-type (ISOFIX) child seat anchors Additional protection is provided by: RSRS (Supplemental Restraint System) RNECK-PRO 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. G WARNING Modifications to or work improperly conducted on restraint system components or their wiring, as well as tampering with interconnected electronic systems, can lead to the restraint systems no longer functioning as intended. Air bags or Emergency Tensioning Devices (ETDs), for example, could deploy inadvertently or fail to deploy in accidents although the deceleration threshold for air bag deployment is exceeded. Therefore, never modify the restraint systems. Do not tamper with electronic components or their software. i See "Children in the vehicle" (Y page 59) for more information on infants and children traveling with you in the vehicle and restraints for infants and children. SRS (Supplemental Restraint System) Introduction SRS consists of: Rthe 6 SRS warning lamp Rair bags Rair bag control unit (with crash sensors) REmergency Tensioning Devices Rbelt force limiters SRS reduces the risk of occupants coming into contact with the vehicle's interior in the event of an accident. It can also reduce the effect of the forces to which occupants are subjected during an accident. SRS warning lamp SRS functions are checked regularly when you switch on the ignition and when the engine is running. Therefore, malfunctions can be detected in good time. The 6 SRS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started. The SRS components are in operational readiness if the 6 SRS warning lamp is not lit while the engine is running. G WARNING The SRS self-check has detected a malfunction if the 6 SRS indicator lamp: Rdoes not light up at all Rdoes not go out after approximately four seconds after the engine is started Rcomes on after the engine was started or while driving. For your safety, Mercedes-Benz strongly recommends that you have the system checked as soon as possible at an authorized Mercedes-Benz Center. 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 an authorized Mercedes-Benz Center. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for further information contact our Customer Assistance center at 1-800-FOR-MERCedes (1-800-367-6372). Safety guidelines for seat belts, Emergency Tensioning Devices (ETDs) and air bags G WARNING RDamaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Their anchoring points must also be checked. Only use seat belts installed or supplied by an authorized Mercedes-Benz Center. RAir bags and pyrotechnic Emergency Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and regard for the Occupant safety 45 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. PRE- SAFE® 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 - outer side of front seat bolsters - side trim next to the rear seat backrest front-passenger air bag cover 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. 46 Occupant safety 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 front- passenger front air bags and driver's knee bag) Rside impacts (side impact air bags and window curtain 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 or the rear side trim panel where the side impact air bag inflates. This could result in serious or fatal injuries should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint or booster seat recommended for the size and weight of the child. Failure to follow these instructions can result in severe injuries to you or other occupants. If you sell your vehicle, it is important that you make the buyer aware of this safety information. Be sure to give the buyer this Operator's Manual. G WARNING Accident research shows that the safest place for children in an automobile is in a rear seat. There is a possibility for a side impact air bag- related injury 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) Occupants, especially children, should never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious injuries or death should Occupant safety 47 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. and for children 12 years old and under, use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Always wear seat belts properly. (2) (3) If you believe that, even with the use of these guidelines, it would be safer for your rear seat occupants to have the rear mounted side impact air bags deactivated, then deactivation can be carried out upon your written request at an authorized Mercedes- Benz Center at an additional cost. Please contact an authorized Mercedes-Benz Center or call the Customer Assistance Center (in the USA) at 1-800-FOR-MERCedes (1-800-367-6372), or Customer Service (in Canada) at 1-800-387-0100 for details. The air bags are only deployed if the air bag control unit detects the need for deployment. Only in the event of such a situation will they provide their supplemental protection. The driver and passenger should always wear their seat belts. Otherwise, it is not possible for the air bags to provide their supplemental protection. In the event of other types of impacts and impacts below air bag deployment thresholds, the air bags will not deploy. The driver and passengers will then be protected to the extent possible by a properly fastened seat belt. A properly fastened seat belt is also needed to provide the best possible protection in a rollover. Air bags provide additional protection; they are not, however, a substitute for seat belts. All vehicle occupants must fasten their seat 48 Occupant safety belts regardless of whether your vehicle is equipped with air bags or not. It is important for your safety and that of your passenger to have deployed air bags replaced and to have any malfunctioning air bags repaired. This will help to make sure the air bags continue to perform their protective function for the vehicle occupants in the event of a crash. Front air bags The front air bags increase protection for the driver's and front passenger's head and chest. : Driver's air bag ; Front-passenger front air bag = Knee bag Driver's air bag : deploys in front of the steering wheel; front-passenger front air bag ; deploys in front of and above the glove box. They are deployed: Rat the start of an accident with a high rate of vehicle acceleration or deceleration in a longitudinal direction Rif the system determines that air bag deployment can offer additional protection to that provided by the seat belt Rdepending on whether the seat belt is being used Rindependently of other air bags in the vehicle If the vehicle rolls over, the front air bags are generally not deployed. If the system detects high vehicle deceleration in a longitudinal direction, the front air bags are deployed. 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 50). 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 be deployed if: Rthe system, based on the OCS weight sensor readings, detects that the front- passenger seat is occupied Rthe PASSENGER AIR BAG OFF indicator lamp on the center console is not lit (Y page 50) Rthe air bag control unit predicts a high impact severity Driver's knee bag Driver's knee bag =(Y page 48) provides additional protection for the driver against: Rknee injuries Rthigh injuries Rlower leg injuries Driver's knee bag =(Y page 48) deploys below the steering wheel. During a frontal impact, if the system determines that air bag deployment can offer additional protection to that provided by the seat belt, driver's knee bag =(Y page 48) is deployed along with the driver's air bag. Driver's knee bag=(Y page 48) operates best in conjunction with a properly positioned and fastened seat belt. Side impact air bags G WARNING The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers. Improper repair work on the doors or the modification or addition of components to the doors create a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment. Work on the doors must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. G WARNING Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat covers may interfere with or prevent the deployment of the side impact air bags. Contact an authorized Mercedes-Benz Center for availability. Occupant safety 49 When deployed, the side impact air bags offer additional protection for the thorax of the vehicle occupants on the side of the vehicle on which the impact occurs. However, they do not protect the: Rhead Rneck Rarms Front side impact air bags : and rear side impact air bags ; deploy next to the outer seat cushions. The side impact air bags are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact Rindependently of the use of the seat belt Rindependently of the front air bags Rindependently of the ETDs If the vehicle overturns, the side impact air bags are generally not deployed. Exception: if the system detects high vehicle deceleration or acceleration in a lateral direction and determines that deployment can offer additional protection to that provided by the seat belt. Side impact air bags will not deploy in side impacts which do not exceed the system's preset deployment thresholds for lateral acceleration/deceleration. You will then be protected by the fastened seat belt. 50 Occupant safety The side impact air bag on the front- passenger side will not deploy under the following conditions: Rthe OCS detects that the front-passenger seat is not occupied. Rthe front-passenger seat belt is not fastened. The side impact air bag on the front- passenger side will deploy if the front- passenger seat belt is fastened, regardless of whether the front-passenger seat is occupied or not. Window curtain air bags The window curtain air bags enhance the level of protection for the head, but not chest or arms, of the vehicle occupants on the side of the vehicle on which the impact occurs. The window curtain air bags are integrated into the side of the roof frame and deploy in the area extending from the front door (A- pillar) to the rear sidewall (C-pillar). Window curtain air bags : are deployed: Ron the side on which an impact occurs Rat the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact Rregardless of whether the front-passenger seat is occupied Rindependently of seat belt use Rif the vehicle overturns and the system determines that window curtain air bag deployment can offer additional protection to that provided by the seat belt Rindependently of the front air bags Window curtain air bags : will not deploy in impacts with deceleration rates which do not exceed the system's preset deployment thresholds for vehicle deceleration or acceleration. You will then be protected by the fastened seat belt. Occupant Classification System (OCS) How the Occupant Classification System works The Occupant Classification System (OCS) categorizes the occupant on the front- passenger seat by means of a weight sensor. The front-passenger front air bag is deactivated automatically for certain weight categories. The 42 indicator lamp shows you the current status. If the 42 indicator lamp is illuminated, the front-passenger front air bag is deactivated. The system does not deactivate: Rthe side impact air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices To be classified correctly, the front passenger must sit: 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 If the front-passenger's weight is transferred to another object in the vehicle (e.g. by leaning on armrests), OCS may not be able to approximate the occupant's weight category. If the front-passenger seat, the seat cover or the seat cushion are damaged, have the necessary repair work carried out at an authorized Mercedes-Benz Center. For safety reasons, Mercedes-Benz recommends that you only use seat accessories that have been approved by Mercedes-Benz. Both the driver and the passenger should always use the 42 indicator lamp as an indication of whether or not the passenger is properly positioned. G WARNING If the 42 indicator lamp lights up when an adult or someone larger than a small individual is in the front-passenger seat, have the front passenger reposition himself or herself in the seat until the 42 indicator lamp goes out. In the event of a collision, the air bag control unit will not allow front-passenger front air bag deployment when the OCS has classified the front-passenger seat occupant as weighing as much as or less than a typical 12- month-old child in a standard child restraint or if the front-passenger seat is classified as being empty. When the OCS senses that the front- passenger seat occupant is classified as being up to or less than the weight of a typical 12-month-old child in a standard child restraint, the 42 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the front- passenger front air bag is deactivated. When the OCS senses that the front- passenger seat is classified as being empty, the 42 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the front- passenger front air bag is deactivated. When the OCS senses that the front- passenger seat occupant is classified as being heavier than the weight of a typical 12- month-old child seated in a standard child restraint or as being a small individual (such as a young teenager or a small adult), the 42 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then, depending on occupant Occupant safety 51 weight sensor readings from the front- passenger seat, remain illuminated or go out. With the 42 indicator lamp illuminated, the front-passenger front air bag is deactivated. With the 42 indicator lamp out, the front-passenger front air bag is activated. When the OCS senses that the front- passenger seat occupant is classified as an adult or someone larger than a small individual, the 42 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 42 indicator lamp is illuminated, the front-passenger front air bag is deactivated and will not be deployed. If the 42 indicator lamp is not illuminated, the front-passenger front air bag is activated and will be deployed: Rin the event of certain frontal impacts Rif impact exceeds a preset deployment threshold Rindependently of the side impact air bags If the front-passenger front air bag is deployed, the rate of inflation will be influenced by: Rthe rate of vehicle deceleration as assessed by the air bag control unit Rthe front passenger's weight category as identified by OCS For further information, see "Air bag display messages" (Y page 364). 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 appropriately sized child restraint system or booster seat 52 Occupant safety recommended for the size and weight of the child. The infant or child restraint system 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 appropriate 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. 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 front- passenger 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 42 indicator lamp is illuminated, indicating that the front- passenger front air bag is deactivated. Should the 42 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 42 indicator lamp while driving to make sure the 42 indicator lamp is illuminated. If the 42 indicator lamp goes out or remains out, do not transport a child on the front-passenger seat until the system has been repaired. A child in a rear-facing child restraint on the front-passenger seat will be seriously injured or even killed if the front-passenger front air bag inflates. RIf you place a child in a forward-facing child restraint on the front-passenger seat: - move the seat as far back as possible - use the proper child restraint recommended for the age, size and weight of the child - secure child restraint with the vehicle's seat belt according to the child seat manufacturer's instructions RFor children larger than a typical 12-month- old child, the front-passenger front air bag can be activated or deactivated. 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 either empty or occupied by a person with a weight up to that of a typical twelve- month-old child seated in a standard child restraint 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. Deactivation takes place although the collision fulfills the criteria for deploying the driver's air bag. Occupant safety 53 System self-test The 42 indicator lamp illuminates when you: Rturn the SmartKey to position 1 or 2 in the ignition lock Rpress the KEYLESS-GO Start/Stop button once or twice If an adult occupant is sitting properly on the front-passenger seat and the OCS classifies the occupant as an adult, the 42 indicator lamp will illuminate and go out again after approximately six seconds. If the seat is not occupied and the OCS classifies the front passenger seat as being unoccupied, the 42 indicator lamp will illuminate and not go out. G WARNING If the 4 2 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.
