GWarning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
6
R does not come on at all
R fails to go out after approximately
4 seconds after the engine was started
R comes on after the engine was started or
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
GWarning!
Air bags are designed to reduce the potential
of injury and fatality in certain
R frontal impacts (front air bags and driver’s
side knee bag)
R side impacts (side impact air bags, window
curtain air bags and pelvis air bags)
R rollovers (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
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.GWarning!
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:
R Sit with the seat belt properly fastened in a
position that is as upright as possible with
your back against the seat backrest.
R Move 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

GObserve Safety notes, see page 87.XPosition seat = and head restraint
properly. See (Y page 88) for seat and

RThe position should be as far rearward from
the front air bag in the steering wheel as
possible, while still permitting proper
operation of vehicle controls.
RAdjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely.
RThe seat must be adjusted so that you can
correctly fasten and position your seat belt.
RThe seat backrest must be in a position that
is as nearly upright as possible.
RAdjust the seat cushion so that the front
edge of the seat cushion lightly supports
your legs.
RAdjust the head restraint so that it is as
close to the head as possible and the
center of the head restraint supports the
back of the head at eye level.
RNever place hands under the seat or near
any moving parts while the seat is being
adjusted.
