14 Introduction
Operator’s Manual
Warning!G
This Sport Utility Vehicle is designed for both on-road and off-road use. It can go places and perform tasks for which conventi onal 2-wheel drive
passenger cars are not intended. This vehi cle will handle and maneuver differently from conventional passenger cars in driving conditions which
may occur on streets, highways and off-road use.
This vehicle has a higher ground clearance and a higher center of gravity than many passenger cars. As with other vehicles of t his type, if you
make sharp turns at excessive speeds or abru pt maneuvers, the vehicle may roll over or may go out of control and crash. Utility vehicles have a
significantly higher rollover rate than ot her types of vehicles. Failure to operate th is vehicle safely may result in an accident, rollover of the vehicle,
and severe or fatal injury.
Before you start to drive this vehicle, read the Operator’s Ma nual. Take time to become familiar with the driving characteristi cs of this vehicle. Be
sure you are familiar with all vehicle contro ls. Learn how your vehicle handles on different road surfaces. Do not attempt sharp turns at excessive
speeds or abrupt maneuvers or other unsafe driving actions that ca n cause loss of vehicle control. When driving off-road or working the vehicle
hard, do not overload it. And, a lways wear your seat belts at all times. In a ro llover crash, an unbelted person is significantly more likely to die than
a person wearing a seat belt.

Introduction
Operating safety
 Operating safety
Proper use of the vehicle
Proper use of the vehi cle 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
interconnected, any modifications made
may produce an undesired effect on other
systems. 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
never 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 ca ution to an area
which is a safe distance from the road.
Inspect the vehicl e underbody and
tires/wheels for possible damage. If the
vehicle 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
repairs.
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 exp licitly instructed to
do so by information on the label itself.
Removal of any of th ese labels may cause
you and others to be unaware of certain
risks which may result in an accident and/or
personal injury.
