16 Introduction
Operating safety
Proper use of the vehicle
Proper use of the vehicle requires that you
are familiar with the following information
and rules:

the safety precautions in this manual

the “Technical data” section in this
manual

traffic rules and regulations

motor vehicle laws and safety stan-
dards
Warning!G
Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because
the vehicle’s electronic components are in-
terconnected, any modifications made may
produce an undesired effect on other sys-
tems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
See an authorized Mercedes-Benz Light
Truck Center for repairs or modifications to
electronic components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function while the
engine is running. You should therefore nev-
er turn off the engine while driving.
Warning!G
Heavy blows against the vehicle underbody
or tires / wheels, for example when running
over an obstacle, road debris or a pothole,
may cause serious damage and impair the
operating safety of your vehicle. If you feel a
sudden significant vibration or ride distur-
bance, or you suspect that damage to your
vehicle has occurred, you should turn on
your hazard warning flashers, carefully slow
down, and drive with caution to an area
which is a safe distance from the road.
Inspect the vehicle underbody and
tires / wheels for possible damage. If the ve-
hicle appears unsafe, have it towed to the
nearest authorized Mercedes-Benz Light
Truck Center or other qualified maintenance
or repair facility for further inspection or re-
pairs.
Warning!G
Various warning labels are attached to your
vehicle. These warning labels are intended
to make you and others aware of various
risks. You should not remove any of these
warning labels unless explicitly instructed to
do so by information on the label itself. Re-
moval of any of these labels may cause you
and others to be unaware of certain risks
which may result in an accident and / or per-
sonal injury.

Warning!G
Do not drive the vehicle without the seat
head restraints. Head restraints are
intended to help reduce injuries during an

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.

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.
