Children 12 years old and under must never
ride in this vehicle, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the ve-
hicle to deactivate the 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.
Infants and small children must be seated in
an appropriate BabySmart
TM compatible in-
fant or child restraint system, which is prop-
erly secured with the vehicle’s seat belt,
fully in accordance with the child seat
manufacturer’s instructions.
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.
!When moving the seats, make sure
there are no items in the footwell or
behind the seats. Otherwise you could
damage the seats.

For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the head re-
straint supports the back of the head at eye
level. This will reduce the potential for injury
to the head and neck in the event of an ac-
cident 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.

BabySmart
TM air bag deactivation
system
175indicator lampSpecial BabySmart
TM compatible child
seats, designed for use with the
Mercedes-Benz system and available at
any authorized Mercedes-Benz Center are
required for use with the BabySmart
TM
air bag deactivation system. With the spe-
cial child seat properly installed, the pas-
senger front air bag will not deploy.
The 75indicator lamp will be il-
luminated, except with the SmartKey re-
moved or in starter switch position0.
Children too big for child restraint systems
should use regular seat belts. Position the
shoulder belt across chest and shoulder, not
face or neck. A booster seat may be neces-
sary to achieve proper belt positioning for
children from 41 lbs until they reach a
height where a lap/shoulder belt fits proper-
ly without a booster.
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.
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 serious
personal injury.
iThe system does not deactivate the
head-thorax air bag and the ETD (emer-
gency tensioning device).
