SeatsWarning!
G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as fas-
tening of seat belts, must be done before
the vehicle is put into motion.Warning!
G
Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the
abdomen or neck. That could cause serious
or fatal injuries. The seat back and seat belts
provide the best restraint when the wearer
is in a nearly upright position and belts are
properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt (
page 46).
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you, and lock the vehicle.
Even with the SmartKey or the 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 unattended in the vehicle, or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and / or serious personal
injury.
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.
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 recom-
mended for the size and weight of the child.
For additional information, see “Children in
the vehicle” (
page 75).
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.

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!

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 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

ment may cause an accident and/or serious
personal injury.

66 Safety and SecurityOccupant safety
Adjust the driver seat as far as possible
rearward, still permitting proper opera-
tion of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the air bag cover
on the steering wheel must be at least
10 in (25 cm) or more. You should be
able to accomplish this by a combina-
tion of adjustments to the seat and
steering wheel. If you have any prob-
lems, please see your authorized
Mercedes-Benz Center.
Do not lean with your head or chest
close to the steering wheel or dash-
board.
Keep hands on the outside of steering
wheel rim. Placing hands and arms in-
side the rim can increase the risk and
potential severity of hand/arm injury
when driver front air bag inflates.
Adjust the front passenger seat as far as
possible rearward from the dashboard
when the seat is occupied.
Occupants, especially children, should
never lean their heads in the area of the
door where the side air bag inflates.
This could result in serious injuries or
death should the air bag be triggered.
Always sit nearly upright, properly use
the seat belts and appropriate size
infant or child restraint system.
Children 12 years old and under 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 installed in the vehicle to deacti-
vate 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.
Failure to follow these instructions can
result in severe injuries to you or other occu-
pants.
If you sell your vehicle you are responsible
to make the buyer aware of these points. Be
sure to give the buyer this Operator’s Manu-
al.
Warning!
G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
It should be noted that with respect to both
front and rear side impact air bags there is a
possibility for a side impact air bag related
injury if occupants, especially children, are
not properly seated or restrained when next
to a side impact air bag which needs to
deploy rapidly in a side impact in order to do
its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Occupants, especially children, should
never place their bodies or lean their
heads in the area of the door where the
side impact air bag inflates. This could
result in serious injuries or death should
the side impact air bag be deployed.
