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 540).
You can deactivate the automatic locking
mode using the control system
(

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 vehi-
cle, 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
preset 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
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. Do not leave children unat-

Warning!G
When occupants have entered or exited the
vehicle using the easy-entry/exit feature,
before driving off make sure

the seats are properly locked

the seat backrests are in an upright po-
sition and are properly locked
If a seat and seat backrest are not properly
locked, the seat could move forward and the
seat backrest could fold. You could slide un-
der the seat belt during braking, vehicle ma-
neuvers, or in an accident. If you slide under
it, the belt would apply force at the abdomen
or neck. That could cause serious or even fa-
tal injuries.

not possible for you to exit the vehicle on the
side of the easy-entry seat (
page 132), you
can fold the left side of the seat backrest in the

Front seat active head restraints
You cannot remove the active head
restraints on the driver’s and front

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 45).
For information on active head restraints,
see “Active head restraint” (
page 92).
Rear seats
Warning!G
To help avoid personal injury when folding
the seat backrest forward, make sure that
you move both feet and legs all the way back
and out of the way to avoid them contacting
the seat as it pivots forward.
In order to prevent an accident or any other
potentially dangerous situations when open-
ing the rear door and exiting the vehicle,
make sure that you are aware of the traffic
situation at all times.
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.
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 additional information, see
“Children in the vehicle” (
page 93).
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.
