cle. Unsupervised use of vehicle equipment
may cause an accident and/or serious per-
sonal injury.iThe key can only be withdrawn in

30 Getting startedAdjusting
AdjustingSeats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.Warning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.
Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
back reclined. Sitting in an excessively re-
clined position can be dangerous. You could
slide under the seat belt in a collision. If you
slide under it, the belt would apply force at
the abdomen or neck. That could cause se-
rious or fatal injuries. The seat back and seat
belts provide the best restraint when the
wearer is in an upright position and belts are
properly positioned on the body. Your seat
must be adjusted so that you can correctly
fasten your seat belt (
page 37).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock and lock your ve-
hicle.
The power seats* can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

53 Safety and Security
Occupant safety
AirbagsWarning!
G
Airbags are designed to reduce the potential
of injury in certain frontal (front airbags) im-
pacts, or side (side impact airbags) impacts
which may cause significant injuries. How-
ever, 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.
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.
