Airbags
1Driver airbag
The most effective occupant restraint system yet 
developed for use in production vehicles is the seat belt. 
In some cases, however, the protective effect of a seat 
belt can be further enhanced by an airbag.
The driver airbag is located in the steering wheel hub. 2Front passenger airbag
The passenger front airbag is located in the dashboard 
ahead of the front passenger.

• Sit properly belted in an upright position with 
your back against the backrest.• Adjust the driver’s 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 Light Truck 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 the driver front airbag 
inflates.• Adjust the front passenger seat as far as 
possible rearward from the dashboard when 
the seat is occupied.
• Occupants, especially children, should never 
lean their heads in the area of the door where 
the side airbag inflates. This could result in 
serious injuries or death should the airbag be 
triggered. Always sit upright, properly use the 
seatbelts and appropriate size infant or child 
restraint system.• Children 12 years old and under must never 
ride in the front seat, except in a 
Mercedes-Benz authorized BabySmart
TM 
compatible child seat, which operates with the 
BabySmart
TM system installed in the vehicle to 
deactivate the passenger side front airbag 
when it is properly installed. Otherwise they 
will be struck by the airbag when it inflates in 
a crash. If this happens, serious or fatal injury 
can result.
Failure to follow these instructions can result in 
severe or fatal injuries to you or other occupants.
