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
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 57).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.
iIf PRE-SAFE® has been activated, the front
passenger’s seat and/or electrically adjustable
rear seats* will be moved to a more favorable
seat position.
iThe memory function (page 365) lets you
store the settings for the seat positions together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seats, make sure there are
no items in the footwell or behind the seats; oth-
erwise, you could damage the seats.

When adjusting the front passenger seat,
make sure the seat, if occupied, is as far
from the passenger front air bag as possi-
ble.
Otherwise, the passenger could be seriously
or even fatally injured in the event of an ac-
cident or braking maneuver.
Make sure no one is caught or injured while
the seat is being adjusted.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
switch or the SmartKey with KEYLESS-GO*
removed from the vehicle, the power seats
can be operated when the respective door is
open. Therefore, do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.

You cannot remove the active head re-

Manually adjust the head restraint. Push or pull on the upper edge of the

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.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.
iAdjust the head restraint in such a way that
it is as close to the head as possible.
i Depending on the seat’s set fore and aft po-
sition, the head restraint height is automatically
pre-set.
i The head restraint on the front passenger’s
side is automatically lowered all the way down
while the vehicle is in motion if no one is sitting
on the seat. This helps you to acquire a better
all-round view.

dren should be seated in a properly se-
cured restraint system that complies with
U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213 and

Fastening the seat belts
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 seat 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 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 restraints or toddler restraints or
children in booster seats, always follow
the child seat manufacturer’s instruc-
tions.
Check your seat belt during travel to
make sure that it is properly posi-
tioned.
Make sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.For more information, see “Seat belts”
(
page 52).
Seat belt height adjustment
The vehicle automatically adjusts the seat
belt height for the driver’s and front pas-
senger’s seats as well as for the rear outer
seats. Comply with the instructions on how
to properly fasten a seat belt
(
page 368).
Warning!G
Do not pass seat belts over sharp edges.
They could tear.
Do not allow the seat belt to get caught in
the door or in the seat adjustment mecha-
nism. This could damage the seat belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the seat 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 seat belts that were
highly stressed in an accident must be re-
placed. Contact an authorized
Mercedes-Benz Center.
