AdjustingSeatsWarning!
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
back reclined. Sitting in an extremely re-
clined position 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 se-
rious or fatal injuries. The seat back and seat
belts provide the best restraint when the
wearer is in an upright position and belts are
properly positioned on the body.
Your seat must be adjusted so that you can
correctly fasten your seat belt.
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
key from the starter switch, take the KEY-
LESS-GO* card with you, and lock your vehi-
cle.
The power seats can also be operated with
the driver’s or passenger door open. 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
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 ve-
hicle to deactivate the front passenger air-
bag when it is properly installed. Otherwise
they will be struck by the airbag when it in-
flates 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 positions. Infants and small children
must ride in back seats and be seated in an
appropriate infant or child restraint system,
which is properly secured with the vehicle's
seat belt and top tether strap, or secured via
lower anchors and top tether strap, fully in
accordance with the child seat manufactur-
er’s instructions.

the head approximately at ear level.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an acci-
dent.

iThe front passenger seat head restraint
automatically lowers after a few sec-
onds when the front passenger seat is
not occupied.This improves the driver's
outward view as well as the forward
view from the rear passenger compart-
ment.
When the front passenger seat is occu-
pied again, the front passenger head
restraint returns to the last set position
within a few seconds.
If the front passenger seat was moved
fore or aft while not being occupied,
the front passenger seat head restraint
returns to a position that corresponds
best with the seat's axial position when
the seat is occupied again.
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
key from the starter switch, and take the
KEYLESS-GO
* card with you.
The steering wheel adjustment feature can
also be operated with the driver’s door
open. 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.
56 Safety and SecurityOccupant safety
Adjust the driver’s seat as far as possi-
ble rearward, still permitting proper op-
eration of vehicle controls. The distance
from the center of the driver’s breast-
bone to the center of the airbag cover on
the steering wheel must be at least
10 inches (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 airbag 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 airbag inflates. This
could result in serious injuries or death
should the airbag be triggered. Always
sit upright, properly use the seat belts
and appropriate size infant or child re-
straint 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 airbag when it
is properly installed. Otherwise they will
be struck by the airbag when it inflates
in a crash. If this happens, serious or fa-
tal injury will result.
Failure to follow these instructions can re-
sult 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. Should you choose to place a child
12 years old or under in the front passenger
seat of your vehicle, you must properly use
a BabySmart
TM child restraint which will
turn off the passenger front airbag.
BabySmart
TM will not, however, turn off any
side impact airbag.
It should be noted that with respect to both
front and rear side impact airbags there is a
possibility for a side airbag related injury if
occupants, especially children, are not prop-
erly seated or restrained when next to a side
airbag 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 airbag inflates. This could result in

Warning!
G
The seat belts provide protection only with
the backrest locked in place and, therefore,
must be locked in place with the vehicle in
motion. Do not drive the vehicle when the
backrest is not locked in place. If the warn-
ing message
SEAT BACKREST, RIGHT -
LOCK
or
SEAT BACKREST, LEFT - LOCK
is
displayed in the multifunction display, then
the respective backrest is not engaged in its
lock. Carefully slow down, and drive with
caution to an area which is in a safe distance
from the roadway. Always provide sufficient
room behind the backrest and fold the back-
rest all the way back until it locks in place.
Keep the area around head restraints clear
of articles (e.g. clothing) to not obstruct the
folding operation of the head restraints.
The warning message is no longer displayed
as soon as the backrest is locked in place. If
both backrests are locked in place and the
warning message is still displayed, have the
system checked at your authorized Mer-
cedes-Benz Center immediately.
When leaving the vehicle, always remove the
electronic key from the starter switch, take
the KEYLESS-GO* card with you, and lock
your vehicle.
The power seats can also be operated with
the driver’s or passenger door open. 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.
Never place hands under seat or near any
moving parts during a seat adjustment pro-
cedure.
