KEYLESS-GO*, you can close the tailgate
and lock the vehicle simultaneously from
the outside using the KEYLESS-GO* lock-
ing/closing switch.

Automatic central locking
The doors and the tailgate lock automati-
cally when the ignition is switched on and
the wheels are turning at vehicle speeds of
approximately 9 mph (15 km/h) or more.
For information on towing the vehicle, see
“Towing the vehicle” (
page 513).
You can deactivate the automatic locking
mode using the control system
(
page 183).
Locking and unlocking from the inside
You can lock or unlock the doors and the
tailgate from inside using the central lock-
ing or unlocking switch. This can be useful,
for example, if you want to lock the vehicle
before starting to drive.
The fuel filler flap cannot be locked or un-
locked with the central locking or unlock-
ing switch.Even with the SmartKey with KEYLESS-GO*
removed from the vehicle, the tailgate
closing switch can be operated. Therefore,
do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
A child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.
iTo prevent a possible inadvertent lockout,
the tailgate will open automatically if a SmartKey
with KEYLESS-GO* is recognized inside the
vehicle.
iYou can open a locked door from the inside.
Open door only when conditions are safe to do
so.
iThe doors unlock automatically after an
accident if the force of the impact exceeds a pre-
set threshold.
The vehicle automatically locks when the
ignition is switched on and the wheels are
turning at vehicle speeds of approximately
9 mph (15 km/h) or more. You could therefore
lock yourself out when the vehicle

is pushed or towed

is on a test stand
Warning!G

SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-

ond-row seat backrests must be properly
locked either in the upright position or,

ment, in the fully folded position while the

If a seat and seat backrest are not properly
locked, the seat could move forward and the
seat backrest could fold. You could slide
under the seat belt during braking, vehicle
maneuvers, or in an accident. If you slide
under it, the seat belt would apply force at
the abdomen or neck. That could cause se-
rious or even fatal injuries.

Seats
Front seat active head restraints
You cannot remove the active head
restraints on the driver’s and front passen-
ger’s seat.
For removal of the active head restraints
we recommend that you contact an
authorized Mercedes-Benz Light Truck
Center.
For information on head restraint adjust-
ment, see “Seats” (
page 43).
For information on active head restraints,
see “Active head restraints” (
page 86).
Rear seats Rear seat adjustment
Warning!G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is 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.
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. Re-
gardless 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 recom-
mended for the size and weight of the child.
For additional information, see “Children in
the vehicle” (
page 87).
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.
Warning!G
Never ride in a moving vehicle with the seat
backrest 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 50).
Never place hands under the seat or near
any moving parts while a seat is being
adjusted.

Warning!G
Do not drive the vehicle without the seat
head restraints installed when the rear seats
are occupied. Head restraints are intended
to help reduce injuries during an accident.
With the second-row middle seat* or a
third-row seat occupied, make sure to move
the respective head restraint up from the
lowest non-use position and have the occu-
pant adjust the head restraint properly.
For your protection, drive only with properly
positioned head restraints.

it is as close to the head as possible and 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.
iWhen removing or installing the head
restraint of an outboard second-row seat, adjust
the seat to the rear as far as possible
(
page 134) and fold the seat backrest
(
page 129) forward.
