Warning!
G
Getting out of your vehicle with the gear se-
lector lever* not fully engaged in positionP
(manual transmission: first or reverse gear)
is dangerous. Also, when parked on an in-
cline, positionP (manual transmission: first
or reverse gear) alone may not prevent your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, turn the front
wheels towards the road curb.
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake and/or
move the gear selector lever* from
positionP (manual transmission: into
Neutral), either of which could result in an
accident and/or serious injury.

To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.

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 work on the SRS cre-
ates a risk of rendering the SRS inoperative
or causing unintended air bag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact an
authorized Mercedes-Benz Center.
Warning!
G
Air bags are designed to reduce the poten-
tial of injury in certain frontal impacts (front
air bags, kneebags), or side impacts
(head-thorax air bags) which may cause sig-
nificant injuries. However, no system avail-
able 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 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 properly posi-
tioned 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.

64 Safety and SecurityOccupant safety
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 air bag 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 the
steering wheel. If you have any prob-
lems, please see an 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 the steer-
ing wheel rim. Placing hands and arms
inside the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag inflates.
Adjust the passenger seat as far as pos-
sible 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 head-thorax air bag in-
flates. This could result in serious inju-
ries or death should the air bag be
triggered. Always sit nearly upright,
properly use the seat belts and appropri-
ately sized infant or child restraint sys-
tem.
Children 12 years old and under must
never ride in this vehicle, except in a
Mercedes-Benz authorized
BabySmart
TM1
compatible child seat,
which operates with the BabySmart
TM
system installed in the vehicle to deacti-
vate the passenger front air bag when it
is properly installed. Otherwise, they will
be struck by the air bag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
