Sport Utility Vehicle
GWARNING
This Sport Utility Vehicle is designed for both
on-road and off-road use. It can go places and
perform tasks for which conventional 2-wheel
drive passenger cars are not intended. This
vehicle 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 this
type, if you make sharp turns at excessive
speeds or abrupt maneuvers, the vehicle may
roll over or may go out of control and crash.
Utility vehicles have a significantly higher
rollover rate than other types of vehicles.
Failure to operate this 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 Manual. Take time to become
familiar with the driving characteristics of this
vehicle. Be sure you are familiar with all
vehicle controls. 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 can cause loss of vehicle control.

142RefuelingDriving and parking

GWARNING
Never depress the brake pedal continuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the braking distance
and can lead to the brakes failing completely.
GWARNING
Under no circumstances try to straighten the
vehicle/trailer combination by increasing the
speed.
General information
R Do not exceed the legally prescribed
maximum speed for vehicle/trailer
combinations in the relevant country.
This lowers the risk of an accident.
R Only install an approved trailer coupling on
your vehicle.
Further information on availability and on
installation is available from any authorized
Mercedes-Benz Center.
R The bumpers of your vehicle are not
suitable for installing detachable trailer
couplings.
R Do not install hired trailer couplings or
other detachable trailer couplings on the
bumpers of your vehicle.
R To reduce the risk of damage to the ball
coupling, remove it from the ball coupling
recess when not in use.
i When towing a trailer, set the tire
pressure on the rear axle of the towing
vehicle for a maximum load; see the tire
pressure table in the fuel filler flap
( Y page 291).
You will find installation dimensions and loads
in the "Technical data" section
( Y page 308).
The maximum noseweight of the trailer
drawbar on the ball coupling is 20
. However,
the actual noseweight must not exceed the
value given on the trailer tow hitch or trailer
identification plates. The lowest weight
applies.
! Use a drawbar noseweight as close as
possible to the maximum permissible
noseweight. Do not use a noseweight that
is under the minimum permissible
noseweight; the trailer may otherwise
come loose. Missing values were not
available at time of going to print.
Note that the payload and the rear axle load
are reduced by the actual payload.
Please note that when towing a trailer,
PARKTRONIC ( Y page 154) is only available
with limitations, or not at all.
i On vehicles without level control, the
height of the ball coupling will alter
according to the load placed on the vehicle.
If necessary, use a trailer with a height-
adjustable drawbar.
Driving tips
i Observe the notes on ESP ®
trailer
stabilization ( Y page 64).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check
the trailer's documents to see what the
maximum permitted speed is. Observe the
legally prescribed maximum speed in the
relevant country.
For certain Mercedes-Benz vehicles, the
maximum permissible rear axle load is
increased when towing a trailer. Refer to the
"Technical data" section to find out whether
this applies to your vehicle. If you utilize any
of the added maximum rear axle load when
towing a trailer, the vehicle/trailer
combination may not exceed a maximum
speed of 60 mph(100 km/h) for reasons
concerning the operating permit. This also
applies in countries in which the permissible
