Warning!G
According to accident statistics, children 
are safer when properly restrained in the 
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend 
that children be placed in the rear seats 
whenever possible. Regardless of seating 
position, children 12 years old and under 
must be seated and properly secured in an 
appropriate infant, or toddler restraint, or 
booster seat recommended for the size and 
weight of the child. For additional 
information, see “Children in the vehicle” 
(
page 74).
A child’s risk of serious or fatal injuries is 
significantly increased if the child restraints 
are not properly secured in the vehicle 
and/or the child is not properly secured in 
the child restraint.
!When moving the seats, make sure that 
there are no items in the footwell or behind the 
seat. Otherwise you could damage the seats.

Belt outlet height adjustment
1Release button
Press release button1 and move the 
seat belt height adjuster upward or 
downward.
Proper use of seat belts
Do not twist the seat belt when fasten-
ing.
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.
