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. For this purpose, you can adjust
the height of the belt outlet.


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 nearly
upright position.


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. 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 during travel to
make sure that it is properly posi-
tioned.


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.
