Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust 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 potential 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 possi-
ble.
Warning!
G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock your vehicle.
Even with the SmartKey removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
the steering wheel adjustment feature can
be operated when the driver’s door is open.
Therefore, do not leave children unattended
in the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

Proper use of seat belts
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.
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 per-
son 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 periodically dur-
ing travel to make sure that it is proper-
ly positioned.
Make sure that the seat belt is always
fitted snugly. Take special care of this
when wearing loose clothing.

BabySmart

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
special child seat properly installed, the
passenger front air bag will not deploy.
The 75indicator lamp locat-
ed in the center console will be illuminat-
ed, except with the SmartKey removed or
in starter switch position0.
Occupants, especially children, should nev-
er lean their heads in the area of the door
where the side air bag inflates. This could re-
sult in serious injuries or death should the
air bag be triggered. Always sit nearly up-
right, properly use the seat belts and appro-
priate size infant or child restraint system.
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 child restraint systems
must ride in back seats using regular seat
belts. Position shoulder belt across chest
and shoulder, not face or neck. A booster
seat may be necessary to achieve proper
belt positioning for children from 41 lbs 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
vehicle, 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.
iThe system does not deactivate the
side impact air bag, the window curtain
air bag and the emergency tensioning
device.
81 Safety and Security
Occupant safety
Once the top tether anchorage hook is
attached, the child restraint itself can be
secured. Tighten the top tether strap
according to the child restraint manufac-
turer’s instructions.
Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(Lower A
nchors and T

the installation of a “LATCH” child seat
with the matching mounting fittings.
The anchors are located behind an uphol-
stery blend.1Indicates the position of the anchors
2Anchors
Lift upholstery blend up to access the
anchors.
Install child seat according to the
manufacturer’s instructions.
iFor safety, make sure the hook2 has
attached to the ring3 beyond the
safety catch, as illustrated.
iNon-LATCH type child seats may also
be used and can be installed using the
vehicle’s seat belt system. Install child
seat according to the manufacturer’s
instructions.
Warning!
G
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 belt positioning
for children over 41 lbs until they reach a
height where a lap/shoulder belt fits proper-
ly without a booster.
Install child seat according to manufactur-
er’s instructions.
The child seat must be firmly attached in the
right and left side anchors1.
An incorrectly mounted child seat may come
loose during an accident which could result
in serious injury or death to the child.
Damaged or impact damaged child seats or
child seat mounting fittings must be re-
placed.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system.
