Backrest
Folding forward:
Lift release lever and fold backrest forward. The seat
will automatically slide forward and the head restraint
will move down.
Folding back:
Lift release lever and fold backrest back. The seat and
head restraint return to their previous positions.
To interrupt the procedure, activate the power seat
switch located in the front door.
Wa r n i n 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 warning message “SEAT BACKREST
LEFT – LOCK!” or “SEAT BACKREST RIGHT –
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 backrest all the way back
until it locks in place.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 Mercedes-Benz Center
immediately.

With the electronic key in starter switch position 2, a
warning sounds for a short time if the driver’s seat belt
is not fastened.
Automatic comfort-fit seat belt:
An automatic comfort-fit feature for driver and front
passenger seat belt is activated when the electronic key
in the starter switch is turned to position 1 or 2.
The retraction force of the inertia reel is reduced,
increasing the level of seat belt comfort.
Note:
For cleaning and care of the seat belts see page 382.
Wa r n i n g !
The seat belts provide protection only with the
backrest locked in place. Do not drive the vehicle
when the backrest is not locked in place. If the
warning message “SEAT BACKREST LEFT – LOCK!”
or “SEAT BACKREST RIGHT – LOCK!” is displayed
in the multifunction display, then the respective
backrest is not engaged in its lock. For backrest see
page 72.Never ride in a moving vehicle with the backrest
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 even fatal injuries. The
backrest and seat belt provide the best restraint
when the wearer is in an upright position and the
belt is properly positioned on the body.

• Occupants, especially children, should never
lean their heads in the area of the door or rear
quarter interior trim panel 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
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
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.
Wa r n i n 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 side
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 properly 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 front door or rear
quarter trim panels where the side airbag inflates.
This could result in serious injuries or death
should the side airbag be activated; (2) always sit
upright, properly use the seat belts and use an
appropriately sized infant or child restraint system
for all children 12 years old or under; and (3)
always wear seat belts properly.
If you believe that, even with the use of these
guidelines, it would be safer for your rear seat
occupants to have both rear quarter trim panel
mounted side airbags deactivated, then
deactivation can be accomplished upon your
written election to do so at your authorized
Mercedes-Benz Center at an additional cost. Please
contact your local authorized Mercedes-Benz
Center or call our Client Assistance Center at
1-800-FOR-MERCedes (1-800-367-6372) for details.

The automatic antiglare function does not react, if
incoming light is not aimed directly at sensors in the
mirror.
