Front seat adjustment
To operate the front power seat adjustment switches,
turn the electronic key in starter switch to position 1
or 2 (with a front door open, the power seats can also be
operated with the electronic key removed or in starter
switch position 0).
Wa r n i n 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 excessively reclined 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 serious 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.Never place hands under seat or near any moving
parts while a seat is being adjusted.
When leaving the vehicle always remove the
electronic key from the starter switch, and lock
your vehicle. The power seats can also be operated with the
driver’s or front passenger door open. Do not leave
children unattended in the vehicle, or with access
to an unl ocked vehic l e. Uns upervi s ed us e of vehi cl e
equipment may cause serious personal injury.

• Sit properly belted in an upright position with
your back against the backrest.• Adjust the driver seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Center.• Do not lean with your head or chest close to the
steering wheel or dashboard.• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside 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.• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized Baby Smart
TM
compatible child seat, which operates with the
BabySmart
TM system installed in the vehicle to
deactivate the passenger side 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 fatal injury
can result.
Failure to follow these instructions can result in
severe injuries to you or other occupants.
