the presence of water sprayed on the 
windshield, and wipers may be dam-
aged as a result.
The switch should not be left in inter-

the windshield once every time the en-
gine is started. Dust that accumulates 
on the windshield might scratch the 
glass and/or damage the wiper blades 
when wiping occurs on a dry wind-
shield.

Parking and locking
You have now completed your first drive. 
You have properly stopped and parked 
your vehicle. End your drive as follows.Warning!

With the engine not running, there is no 
power assistance for the brake and the 
steering systems. In this case, it is impor-
tant to keep in mind that a considerably

and steer the vehicle.
Warning!
G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay, or 
leaves can come into contact with the hot 
exhaust system, as these materials could be 
ignited and cause a vehicle fire.
To reduce the risk of personal injury as a re-
sult of vehicle movement, before turning off 
the engine and leaving the vehicle always:
Keep right foot on brake pedal.
Firmly depress parking brake pedal.
Move the gear selector lever to 
positionP.
Slowly release brake pedal.
When parked on an incline, turn front 
wheel towards the road curb.
Turn the SmartKey to starter switch 
position0 and remove, or press

61 Safety and Security
Occupant safety
Air bags
Warning!
G
In the event that the 1 indicator lamp 
comes on during driving or does not come 
on at all, the SRS self-check has detected a 
malfunction. For your safety, we strongly 
recommend that you visit an authorized 
Mercedes-Benz Center immediately to have 
the system checked; otherwise the SRS may 
not be activated when needed in an acci-
dent, which could result in serious or fatal 
injury, or it might deploy unexpectedly and 
unnecessarily which could also result in 
injury.
In addition, improper repair work on the SRS 
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only 
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
Warning!
G
Air bags are designed to reduce the poten-
tial of injury and fatality in certain frontal im-
pacts (front air bags), side impacts (side 
impact air bags and head protection window 
curtain air bags) or rollovers (head protec-
tion window curtain air bags). However, no 
system available today can totally eliminate 
injuries and fatalities.
The activation of the air bags temporarily re-
leases a small amount of dust from the 
air bags. This dust, however, is neither inju-
rious to your health, nor does it indicate a 
fire in the vehicle. The dust might cause 
some temporary breathing difficulty for peo-
ple 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 front to always be in a 
properly seated position and to wear your 
seat belts.
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 and hands 
on steering wheel position will help to keep 
you at a safe distance from the air bag. Oc-
cupants who are unbelted, out of position or 
too close to the air bag can be seriously in-
jured by an air bag as it inflates with great 
force in the blink of an eye:
Sit properly belted in a nearly upright 
position with your back against the seat 
backrest.
