dent.

on your hips (over hip joint) and not
across the abdomen.
Place the seat backrest in a nearly up-
right position.
Never use a seat belt for more than one
person at a time.
Do not fasten a seat belt around a per-
son and another object at the same
time. When using a seat belt to secure
infant or toddler restraints or children
in booster seats, always follow the
child seat manufacturer's instructions.
Check your seat belt periodically dur-
ing travel to make sure that it is proper-
ly positioned.
Make sure that 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.
