90 Safety and SecurityOccupant safetyA statement by the child restraint
manufacturer of compliance with these
standards can be found on the instruction
label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint
system, be sure to carefully read and
follow all manufacturer’s instructions for
installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and to
infant or child restraints.
Warning!
G
Canada only: Children 12 years old and un-
der must never ride in the front seat, except
in a Mercedes-Benz authorized
BabySmart
TM compatible child seat, which
operates with the BabySmart
TM system in-
stalled in the vehicle to deactivate the front
passenger front air bag when it is properly
installed. Otherwise they will be struck by
the air bag when it inflates in a crash. If this
happens, serious or fatal injury will result.
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 child restraint recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s instruc-
tions.
Always sit nearly upright, properly use the
seat belts and for children 12 years old and
under, use an appropriately sized infant re-
straint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances re-
quire you to place a child in the front
passenger seat:
USA only: Your vehicle is equipped with
air bag technology designed to turn off
the front passenger front air bag in your
vehicle when the OCS senses the weight
of a typical 12-month-old child or less
along with the weight of a standard ap-
propriate child restraint on the front
passenger seat.

Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.Not foldable rear seat backrest

Remove cover1 from anchorage
ring3 (
page 93).
Store cover1 in a convenient place
(e.g. glove box).
Guide tether strap between head re-
straint and top of the seat back.
Head restraint must be installed (if re-
movable) and positioned such that the
top tether strap can pass freely be-
tween the head restraint and the top of
the seat back.
Warning!
G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
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.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper seat belt posi-
tioning for children over 41 lb until they
reach a height where a lap/shoulder belt fits
properly without a booster.
When the child restraint is not in use, re-
move it from the vehicle or secure it with the
seat belt to prevent the child restraint from
becoming a projectile in the event of an ac-
cident.
Do not leave children unattended in the ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and may cause an accident
and/or serious personal injury.

Rear seat head restraints
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that 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.
i
Adjust the head restraint in such a way that
it is as close to the head as possible.Warning!

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.
