50 Getting started
Driving
With a smooth motion, pull the belt out
of the seat belt presenter.
Place the shoulder portion of the belt
across the top of your shoulder and the
lap portion across your hips.
Push latch plate1 into buckle3 until
it clicks.
If necessary, tighten the lap portion to
a snug fit by pulling shoulder portion
up.
Proper use of seat belts

Do not twist the belt when fastening.

Adjust seat belt so that the shoulder
portion is located as close as possible
to the middle of the shoulder (it should
not touch the neck). Never pass the
shoulder portion of the belt under your
arm.

Position the lap belt as low as possible
on your hips (over hip joint) and not
across the abdomen.

Place the seat backrest in a position
that is as upright as possible.

Never use a seat belt for more than one
person at a time.

Do not fasten a seat belt around a
person and another object at the same
time.

W he n u sing a se at b el t to s ec ur e i nfa nt
restraints, toddler restraints or chil-
dren in booster seats, always follow the
child seat manufacturer’s instructions.

Check your seat belt periodically
during travel to make sure it is properly
positioned.

Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
Warning!G
Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.
Contact an authorized Mercedes-Benz
Center.

66 Safety and Security
Occupant safety
Warning!G
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 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 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.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:

Sit properly belted in a position that is
as upright as possible with your back
against the seat backrest.

Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration 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
10 in (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 an authorized
Mercedes-Benz Center.

Do not lean your head or chest close to
the steering wheel or dashboard.

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’s front air bag inflates.

Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.

Occupants, especially children, should
always sit as upright as possible,
properly use the seat belts and use an
appropriately sized infant restraint,
toddler restraint, or booster seat recom-
mended for the size and weight of the
child.
Failure to follow these instructions can re-
sult in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.

Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust 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. This will reduce the po-
tential for injury to the head and neck in the
event of an accident or similar situation.
Warning!G
For safety reasons, always drive with the
rear head restraints in the upright position
when the rear seats are occupied.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
iAdjust the head restraint in such a way that
it is as close to the head as possible.
