Operating safety


G Warning! Work improperly carried out on electronic components and associated software could cause them to cease functioning. Because the vehicle’s electronic components are interconnected, any modifications made may produce an undesired effect on other systems. Electronic malfunctions could seriously impair the operating safety of your vehicle. Contact an authorized Mercedes-Benz Center for repairs or modifications to electronic components. Other improper work or modifications on the vehicle could also have a negative impact on the operating safety of the vehicle. Some safety systems only function while the engine is running. You should therefore never turn off the engine while driving. G Warning! Heavy blows against the vehicle underbody or tires/wheels may cause serious damage and impair the operating safety of your vehicle. Such blows can be caused, for example, by running over an obstacle, road debris or a pothole. If you feel a sudden significant vibration or ride disturbance, or you suspect that damage to your vehicle as occurred: Rturn on your hazard warning flashers Rslow down carefully Rdrive with caution to an area which is a safe


distance from the road


Inspect the vehicle underbody and tires/ wheels for possible damage. If the vehicle appears unsafe, have it towed to the nearest authorized Mercedes-Benz Center or other qualified maintenance or repair facility for further inspection or repairs.

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.

SRS indicator lamp The SRS system conducts a self-test when the ignition is switched on and in regular intervals while the engine is running. This facilitates detection of system malfunctions. The SRS indicator lamp 6 in the instrument cluster comes on when the ignition is switched on. It goes out no later than a few seconds after the engine has been started. The SRS components are in operational readiness when the SRS indicator lamp 6 is not lit while the engine is running.

while driving


For your safety, we strongly recommend that you contact an authorized Mercedes-Benz Center immediately to have the system checked. Otherwise the SRS may not be activated when needed in an accident, which could result in serious or fatal injury. The SRS might also deploy unexpectedly and unnecessarily which could also result in injury as well. In addition, improper work on the SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center. If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center. USA only: Call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details.


Air bags G Warning! Air bags are designed to reduce the potential of injury and fatality in certain Rfrontal impacts (front air bags and driver’s


side knee bag)


Rside impacts (side impact air bags, window


curtain air bags and pelvis air bags)


However, no system available today can completely eliminate injuries and fatalities.


Occupant safety

Deployment of the air bags temporarily releases a small amount of dust from the air bags. This dust, however, is neither harmful to your health, nor does it indicate a fire in the vehicle. The dust might cause some temporary breathing difficulty for people with asthma or other breathing trouble. To avoid this, you may wish to get out of the vehicle as soon as it is safe to do so. If you have any breathing difficulty but cannot get out of the vehicle after the air bag inflates, then get fresh air by opening a window or door. G Warning! To reduce the risk of injury when the front air bags inflate, it is very important for the driver and front passenger to always be in a properly seated position and to wear their respective seat belt. For maximum protection in the event of a collision always be in normal seated position with your back against the seat backrest. Fasten your seat belt and make sure it is properly positioned on your body. Since the air bag inflates with considerable speed and force, a proper seating position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag as it inflates with great force instantaneously: RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RMove the driver’s seat as far back as


possible, still permitting proper operation of vehicle controls. The distance from the center of the driver’s chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm) or more. You should be able to accomplish this by adjusting the seat and steering wheel. If

you have any difficulties, please contact an authorized Mercedes-Benz Center.


RDo not lean your head or chest close to the


steering wheel or dashboard.


RKeep hands on the outside of the steering wheel rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when the driver front air bag inflates.


RAdjust the front passenger seat as far as


possible rearward from the dashboard when the seat is occupied.


ROccupants, especially children, should


never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious injuries or death should the side impact air bag be deployed. Always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child.


RCanada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ air bag deactivation system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.


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)


(2)


Always sit as upright as possible, wear the seat belt properly, 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.


Air bags are designed to deploy only in certain Rfrontal impacts (front air bags and driver’s


side knee bag)


Rside impacts (side impact air bags, pelvis air bags and window curtain air bags) if the system determines the need for air bag deployment


Only in the event of such a situation will they provide their supplemental protection. The driver and passengers should always wear their seat belts. Otherwise it is not possible for the air bags to provide their supplemental protection. In case of other types of impacts and impacts below air bag deployment thresholds, 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 are not a substitute for seat belts. Always wear your seat belt, regardless of whether or not your vehicle is equipped with air bags. It is important to 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 will continue to provide supplemental crash protection for occupants.


Safety guidelines for the seat belt, Emergency Tensioning Device (ETD) and air bag 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 with your local government’s disposal guidelines. California residents, see www.dtsc.ca.gov/HazardousWaste/ Perchlorate/index.cfm.


RAir bags and ETDs are designed to function on a one-time-only basis. An air bag or ETD that has deployed must be replaced.


RDo not pass seat belts over sharp edges.


They could tear.


RDo not make any modification that could


change the effectiveness of the seat belts. RDo not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. RNo modifications of any kind may be made


to any components or wiring of the SRS.


RDo no change or remove any component or


part of the SRS.


RDo not install additional trim material, seat


covers, badges, etc. over the steering wheel hub, front passenger front air bag cover, outboard sides of the seat


Occupant safety


39


backrests, door trim panels, or door frame trims.


RDo not install additional electrical/


electronic equipment on or near SRS components and wiring.


RKeep area between air bags and occupants


free of objects (e.g. packages, purses, umbrellas, etc.).


RDo not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed.


RAir bag system components will be hot after an air bag has inflated. Do not touch them.


RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.


RImproper repair work on the SRS creates a


risk of rendering the SRS inoperative or causing unintended air bag deployment. Work on the SRS must therefore only be performed by qualified technicians. Contact an authorized Mercedes-Benz Center.


RFor your protection and the protection of others, when scrapping the air bag unit or ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz Center.


RGiven the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment.


If you sell your vehicle, we strongly recommend 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.

The front air bags in this vehicle have been designed to inflate in two stages. This allows the air bags to have different rates of inflation. The rate of inflation is based on the vehicle deceleration rate as assessed by the air bag control unit. Vehicles with OCS, USA only: The front passenger front air bag deployment is additionally influenced by the passenger’s weight category as identified by the Occupant Classification System (OCS) (Y page 42). Vehicles with OCS, USA only: The lighter the front passenger-side occupant, the higher the vehicle deceleration rate required for second
