97 Restraint systems
Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index Your vehicle was originally equipped with airbags 
which are designed to activate in certain impacts 
exceeding a preset threshold to reduce the potential 
and severity of injury. It is important to your safety 
and that of your passenger that you replace deployed 
airbags and repair any malfunctioning airbags to 
ensure the vehicle will continue to provide crash 
protection for occupants.
Wa r n i n g !
To reduce the risk of injury when the front airbags 
inflate, it is very important for the driver and front 
passenger to always be in a properly seated 
position and to wear your seat belt.For maximum protection in the event of a collision 
always be in normal seated position w ith  your back 
against the backrest. Fasten your seat belt and 
ensure that it is properly positioned on your body.Since the airbag inflates with considerable speed 
and force, a proper seating and hands on steering 
wheel position will help to keep you at a safe 
distance from the airbag. Occupants who are 
unbelted, out of position or too close to the airbag 
can be seriously injured by an airbag as it inflates 
with great force in the blink of an eye:
• Sit properly belted in an upright position with 
your back against the backrest.• Adjust the driver seat as far as possible 
rearward, still permitting proper operation of 
vehicle controls. The distance from the center 
of the driver’s breastbone to the center of the 
airbag cover on the steering wheel must be at 
least ten inches (25 cm) or more. You should be 
able to accomplish this by a combination of 
adjustments to the seat and steering wheel. If 
you have any problems, please see your 
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the 
steering wheel or dashboard.• Keep hands on the outside of steering wheel 
rim. Placing hands and arms inside the rim 
can increase the risk and potential severity of 
hand/arm injury when driver front airbag 
inflates.• Adjust the front passenger seat as far as 
possible rearward from the dashboard when 
the seat is occupied.
