Air bags
Warning!G
Air bags are designed to reduce the poten-
tial of injury in certain frontal impacts (front 
air bags, knee bags), or side impacts 
(head-thorax air bags) which may cause 
significant injuries. However, no system 
available today can completely eliminate 
injuries and fatalities.
The deployment of the air bags temporarily 
releases a small amount of dust from the air 
bags. This dust, however, is neither injurious 
to your health, nor does it indicate a fire in 
the vehicle. The dust might cause some tem-
porary 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.
Warning!G
To reduce the risk of injury when the front 
air bags inflate, it is very important for the 
driver and passenger to always be in a prop-
erly seated position and to wear their seat 
belts.
For maximum protection in the event of a 
collision always be in normal seated position 
with your back against the backrest. 
Fasten your seat belt and ensure it is prop-
erly positioned on your body (
page 48).
Since the air bag 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 air bag. 
Occupants who are unbelted, out of position 
or too close to the air bag can be seriously 
injured or killed by an air bag as it inflates 
with great force in the blink of an eye:
Sit properly belted in a position that is 
as upright as possible with your back 
against the seat backrest.
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper 
operation of vehicle controls. The dis-
tance from the center of the driver’s 
breastbone 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 a 
combination of adjustments to the seat 
and steering wheel. If you have any 
problems, please contact an authorized 
Mercedes-Benz Center.
Do not lean your head or chest close to 
the steering wheel or dashboard.
Keep hands on the outside of the steer-
ing wheel rim. Placing hands and arms 
inside the rim can increase the risk and 
potential severity of hand/arm injury 
when the driver’s front air bag inflates.
Adjust the passenger seat as far as pos-
sible rearward from the dashboard when 
the seat is occupied.
