Occupant safety
AirbagsWarning!
G
Airbags are designed to reduce the potential
for injury resulting from certain frontal im-
pacts (front airbags, driver-side kneebag) or
side impacts (head-thorax airbags) which
may cause significant injuries. However, no
system available today can totally eliminate
injuries and fatalities.
The activation of the SRS temporarily releas-
es a small amount of dust from the airbags.
This dust, however, is neither injurious to
your health, nor does it indicate a fire in the
vehicle. The dust might cause some tempo-
rary breathing difficulty for people with asth-
ma 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 airbag inflates, then get
fresh air by opening a window or door.
Warning!
G
To reduce the risk of injury when the front
airbags inflate, it is very important for the
driver and passenger to always be in a prop-
erly 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 backrest. Fasten
your seat belt and ensure that it is properly
positioned on your body (
page 37).
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. Oc-
cupants who are unbelted, out of position or
too close to the airbag can be seriously in-
jured 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 seat back-
rest.
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone 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 combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand / arm injury
when driver front airbag inflates.
Adjust the passenger seat as far as pos-
sible rearward from the dashboard when
the seat is occupied.

When the outside temperature is below
41°F (5°C), only switch to air recirculation
mode for short periods to prevent window
fogging.

side windows will close.
The air recirculation mode is activated
automatically
at high outside temperatures
if the concentration of carbon mon-
oxide and nitrogen oxide in the out-
side air increases, for example in a
tunnel
If you have turned off the air condition-
er (page 155) or the outside
temperature is below 41°F (5°C), the
air recirculation mode will not switch
