Adjusting
Seats
The seats can be adjusted either manually
or electrically, depending on the vehicle’s
equipment.
For more information, see “Seats”
(
page 101).
Warning!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 in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen 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 43).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.
Warning!G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, 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. Unsupervised use of vehicle equip-
ment may cause an accident and/or serious
personal injury.

(
page 101).
Steering wheel
Warning!G
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
intended to help reduce injuries during an
accident.
iAdjust the head restraint in such a way that
it is as close to the head as possible.
Warning!G
Do not adjust the steering wheel while
driving. Adjusting the steering wheel while
driving, or driving without the steering wheel
adjustment feature locked could cause the
driver to lose control of the vehicle.
When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch, the electrical 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. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

function and indicator lamps) on the in-
strument cluster are clearly visible.
Easy-entry/exit feature*
This feature allows for easier entry into and
exit from the vehicle. When entering and
exiting the vehicle, the steering wheel is in
its uppermost position.
The easy-entry/exit feature can be activat-
ed or deactivated in the
Convenience sub-
menu of the control system (
page 144).
iThe memory function* (page 107) lets
you store the settings for the power seat*, the
steering wheel adjustment (electrical*) and the
exterior rear view mirrors.
Warning!G
You must make sure no one can become
trapped or injured by the moving steering
wheel when the easy-entry/exit feature is
activated.
To stop steering wheel movement, do one of
the following:
Move steering wheel adjustment stalk*
(
page 40).
Press memory position switch*
(
page 108).
Do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.

unintentionally activate the easy-entry/exit
feature, which could result in an accident
and/or serious personal injury.

Warning!G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your in-
terior rear view mirror or glance over your
shoulder before changing lanes.
!If an exterior rear view mirror was forcibly
pushed forward (hit from the rear) or forcibly
pushed rearward (hit from the front), reposition
it by applying firm pressure until it snaps into
place. The mirror housing is now properly posi-
tioned and you can adjust the mirror in the usual
manner.
iAt low ambient temperatures, the exterior
rear view mirrors will be heated automatically.
iThe memory function* (page 107) lets
you store the settings for the exterior rear view
mirrors together with the settings for the steer-
ing wheel and the driver’s seat position.
60 Safety and Security
Occupant safety
Warning!G
To reduce the risk of injury when the front
air bags inflate, it is very important for the
driver and front passenger to always be in a
properly seated position and to wear their
respective seat belts.
For maximum protection in the event of a
collision always be in normal seated position
with your back against the backrest. Fasten
your seat belt and make sure that it is prop-
erly positioned on your body.
Since the air bag inflates with considerable
speed and force, a proper seating and hands
on steering wheel position will help to keep
you at a safe distance from the air bag.
Occupants who are unbelted, out of position
or too close to the air bag can be seriously
injured or killed by an air bag as it inflates
with great force in the blink of an eye:
Sit properly belted in a nearly upright
position with your back against the seat
backrest.
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 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 an authorized
Mercedes-Benz Center.
Do not lean your head or chest close to
the steering wheel or dashboard.
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
always sit nearly upright, properly use
the seat belts and use an appropriately
sized infant or toddler restraint or boost-
er seat recommended for the size and
weight of the child.
Failure to follow these instructions can re-
sult in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety in-
formation. Be sure to give the buyer this
Operator’s Manual.

Rear seat head restraints
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the 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 po-
tential for injury to the head and neck in the
event of an accident or similar situation.
iAdjust the head restraint in such a way that
it is as close to the head as possible.
Warning!G
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.
