Adjusting
Adjusting
Seats
Warning!G
All seat, head restraint, steering wheel, and
rear view mirror adjustments, as well as
fastening 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
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 backrest 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 51).
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 or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle.
Even with the SmartKey or the SmartKey
with KEYLESS-GO* removed from the
starter switch or the SmartKey with
KEYLESS-GO* removed from the vehicle,
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.
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
appropriate infant or toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional informa-
tion, see “Children in the vehicle”
(
page 84).
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and
the child is not properly secured in the child
restraint.

or
Open the respective door (vehicles
with memory function*).
The seat can be adjusted with the re-
spective door opened.
or
Open a front door (vehicles without
memory function*).
The seat can be adjusted within
3 minutes after either front door has
been opened.
!When moving the seat, make sure there are
no items in the footwell or behind the seat.
Otherwise you could damage the seat.
!When the second-row seats are folded
forward, e.g. for cargo compartment expansion
(
page 301), 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 215). If the head restraint is in
the uppermost position, it could hit and damage
the sun visor.
iThe memory function* (page 144) lets
you store the settings for the seat position to-
gether with the settings for the steering wheel
and the exterior rear view mirrors.
45 Getting started
Adjusting
Seat fore and aft adjustment
Press the switch forward or backward
in direction of arrow5.
Adjust the seat to a comfortable
seating position that still allows you to
reach the accelerator/brake pedal
safely. The position should be as far to
the rear as possible, consistent with
ability to properly operate controls.
Seat height
Press the switch up or down in
direction of arrow3.
Seat cushion tilt
Press the switch up or down in
direction of arrow2 until your upper
legs are lightly supported.
Seat backrest tilt
Press the switch forward or backward
in direction of arrow4 until your arms
are slightly angled when holding the
steering wheel.Head restraint height
Vehicles with memory function*:
Press switch (page 44) up or down in
direction of arrow1.
Vehicles without memory function:
1Head restraint
2Release button
Warning!G
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an
accident.
With a third-row 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 in such a way 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 potential 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.
46 Getting started
Adjusting
Raising:
Manually adjust the height of head
restraint 1 by pulling it upward.
If head restraint 1 is fully retracted,
push release button 2 in direction of
arrow and pull head restraint 1
upward.
Lowering:
To lower head restraint 1, press
release button 2 in direction of arrow
and push down on head restraint 1.Head restraint fore and aft adjustment
Manually adjust the angle of the head
restraint.
While seated, reach behind you with
both hands and find lower edge of the
head restraint.

Steering wheel
Steering wheel adjustment, manual
Warning!G
Only adjust the steering wheel with the
vehicle at a standstill and make sure the
steering wheel is securely locked in place
before driving off.
Driving without the steering wheel adjust-
ment locked may cause an unexpected
steering wheel movement which could
cause the driver to lose control of the
vehicle. Make sure the steering wheel is
securely locked by trying to move it up and
down, and in and out before driving off.

conditions.iThe memory function* (page 144) lets
you store the settings for the steering wheel
together with the settings for seat positions and
the exterior rear view mirrors.
Warning!G
In case of an accident, liquid electrolyte may
escape the mirror housing if the mirror glass
breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.
!Electrolyte drops coming into contact with
the vehicle paint finish can only be completely
removed while in their liquid state and by apply-
ing plenty of water.
50 Getting started
Adjusting
For more information, see “Rear view mir-
rors” (
page 212).
!Vehicles with power folding exterior rear
view mirrors*:
If an exterior rear view mirror housing is forcibly
pushed forward (hit from the rear) or forcibly
pushed rearward (hit from the front) press fold
button1 (
page 214) to fold mirrors in, then
press fold button1 (
page 214) again to fold
mirrors out. Do not force mirrors by hand as this
may damage the adjustment mechanism.
The mirror housing is then properly positioned
and you can adjust the mirror in the usual man-
ner.
iThe memory function* (page 144) lets
you store the settings for the exterior rear view
mirrors together with the setting for the steering
wheel column and the seat positions.
At low ambient temperatures, the exterior rear
view mirrors will be heated automatically.
