Adjusting
Seat adjustment

the entry side of each front seat base.
1 Head restraint height (vehicles with
memory function)*
2Seat cushion tilt
3Seat height
4Backrest tilt
5Seat fore and aft adjustment
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
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For addi-
tional information, see “Children in the vehi-
cle” (
page 91).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
!When moving the seats, make sure there are
no items in the footwell or behind the seats;
otherwise you could damage the seats.
!When the second-row seats are folded
forward, e.g. for cargo compartment expansion
(
page 304), the front seats may not be moved
to the rearmost position. Otherwise you could
damage the front and second-row seats.
!When adjusting the seat backrest tilt and
head restraint height, make sure the sun visor is
folded up (
page 210). If the head restraint is in
the uppermost position, it could hit and damage
the sun visor.
iVehicles without memory function*:
The seats can be adjusted within 5 minutes after
either front door has been opened. The counter
resets each time

you open or close a front door

you insert the SmartKey into the starter
switch

you remove the SmartKey from the starter
switch

you switch the ignition on or off

Warning!G
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an
accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the
occupant adjust the head restraint properly.
For your protection, drive only with properly
positioned and engaged 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.
!Do not attempt to remove front seat head
restraints. They can only be removed by qualified
technicians. We recommend that you have this
work carried out by an authorized
Mercedes-Benz Light Truck Center.

view mirror button illuminated.
!If an exterior rear view mirror was forcibly
pushed forward (hit from the rear) or forcibly

mirrors out. Do not force mirrors by hand as this
may damage the adjustment mechanism.

ner.
