XClean the headlamps and rear lights and
check for damage.XClean the front and rear license plates.XClean the wheels and tires with a water jet
and remove any foreign objects.XClean the wheels, tires, wheel arches and
the vehicle underside with a water jet;
check for any foreign objects and damage.XCheck whether twigs or other parts of
plants have become trapped. These
increase the risk of fire and can damage
fuel pipes, brake hoses or the rubber
bellows of the axle joints and propeller
shafts.XAfter the trip, examine without fail the
entire undercarriage, wheels, tires, brakes,
bodywork structure, steering, chassis and
exhaust system for damage.XAfter driving for extended periods across
sand, mud, gravel, water or in similarly dirty
conditions, have the brake discs, wheels,
brake pads/linings and axle joints checked
and cleaned.XIf you detect strong vibrations after off-road
driving, check for foreign objects in the
wheels and drivetrain and remove any that
you find. Foreign objects can disturb the
balance and cause vibrations.XTest the brakes.
Driving on sand
GWarning!
Do not reduce the tire inflation pressure
before driving through sand. However, if you
do so, remember to correct the tire inflation
pressure before continuing your trip. Driving
with reduced tire inflation pressure increases
the risk of losing control of the vehicle and
rolling over.
Observe the following rules when driving on
sand:
R shift the transfer case to
LOW (Y page 126).
R avoid high engine speeds.
R limit the shift range of the automatic
transmission according to the off-road
conditions.
R drive quickly to overcome the rolling
resistance. Otherwise, the vehicle could dig
itself into the sand.
R drive in the tracks of other vehicles if
possible. Make sure that the ruts are not
too deep, that the sand is firm enough and
that your vehicle has sufficient ground
clearance.
Tire ruts and gravel roads
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel:
! Check that the ruts are not too deep and
that your vehicle has sufficient clearance.
Otherwise, your vehicle could be damaged
or bottom out and get stuck.
R shift the transfer case to
LOW (Y page 126).
R avoid high engine speeds.
R observe the safety notes (Y page 142) and
the general notes (Y page 142) on off-road
driving.
R restrict the shift range of the automatic
transmission to 1 (Y page 123).
R drive slowly.
R where ruts are too deep, drive with the
wheels of one side on the center grassy
area, if possible.

RAvoid high engine speeds – drive at
appropriate engine speeds (no more than
3000 rpm).
R Use the braking power of the engine when
driving down a slope. Observe the engine
speed, do not overrev the engine.
i Further information on the maximum
engine speed can be found in the
"Tachometer" and "Technical Data"
sections.
R Select a shift range appropriate to the
gradient.
R Before tackling steep downhill gradients,
select shift range 1 (Y page 123).
R Check the brakes after driving off-road for
a long time.GWarning!
Never turn the vehicle around on steep
inclines. The vehicle might roll over. If the
vehicle cannot complete the attempted climb,
back it down in reverse gear.
i Hill start assist will aid you when pulling
away on a hill.
For more information, see "Hill start assist"
( Y page 118).
Maximum gradient-climbing capability
Do not drive at an angle on slopes, inclines or
gradients, but instead follow the direct line of
fall. The maximum gradient-climbing
capability of your vehicle is 80%, which
corresponds to an approach/departure angle
of 38°. Note that the vehicle's gradient-
climbing capability depends on the off-road
conditions.
Accelerate carefully and make sure that the
wheels do not spin when driving on steep
terrain.
i If the load on the front axle is reduced
when pulling away on a steep uphill slope,
the front wheels have a tendency to spin.
4ETS detects this and brakes the wheels
accordingly. The rear wheel torque is
increased, making it easier to drive off.
Brow of hill
When driving on an uphill gradient, reduce
pressure slightly on the accelerator
immediately before reaching the top of the hill
(do not shift the transmission to position N).
Use the vehicle's own impetus to drive over
the top of the hill.
This style of driving prevents:
R the vehicle from lifting off the ground on the
brow of a hill
R loss of traction
R the vehicle from traveling too quickly down
the other side
Driving downhill
R Before tackling steep downhill gradients,
select shift range 1 (Y page 123).
This way you use the engine's braking
effect to reduce the speed. If this is not
sufficient, brake gently. When doing so,
make sure that the vehicle is facing in the
direction of the line of fall.
R Observe the notes on driving in
mountainous terrain ( Y page 146).
R Drive slowly.
R Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight.
Otherwise, the vehicle could slip sideways,
tip and rollover.
R Check that the brakes are working normally
after a long downhill stretch.
i The special off-road ABS( Y page 56)
enables accurate, brief and repeated
locking of the front wheels, causing them
to dig into the loose ground. Note that when
the front wheels are fully braked, they slide
easily over the surface of the ground,
making it difficult to steer.

Range of the sensors
The sensors must be free of dirt, ice and
slush; otherwise they may not function
correctly. Clean the sensors regularly, taking
care not to scratch or damage them
( Y page 224).

! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer towbars. The
ultrasonic backing up aid does not detect
such objects when they are in the
immediate vicinity of the vehicle. You could
damage the vehicle or the objects.
Ultrasonic sources such as an automatic
car wash, a lorry's compressed-air brakes
or a pneumatic drill could cause the
ultrasonic backing up aid to malfunction.
Minimum distanceCenterApprox. 8 in (approx.

If there is an obstacle within this range, all
warning displays flash and a warning tone
sounds. If the distance falls below the
minimum, the distance may no longer be
shown.
Warning displays
The warning display shows the distance
between the sensors and the obstacle.
The warning display is in the rear
compartment next to the rear door.
The warning display is divided into four yellow
and two red segments :. The ultrasonic
backing up aid is ready for use when you hear
a warning tone and segment ; lights up
briefly.
One or more segments : light up as the
vehicle approaches an obstacle, depending
on the distance from the obstacle.

Important safety notes
The rear view camera is an optical parking aid.
It shows the area behind your vehicle in the
COMAND display.
GWarning!
Make sure no persons or animals are in or
near the area in which you are parking/
maneuvering. Otherwise, they could be
injured.
The rear view camera is in the tailgate above
the rear window wiper.

The rear view camera does not relieve you of
the responsibility to be cautious. Take care
and pay careful attention. The rear view
camera may not show objects which are
R very close to the rear bumper
R under the rear bumper
R under the spare wheel
R nearby behind the spare wheel
You are responsible for safety at all times and
must continue to pay attention to the
immediate surroundings when parking and
maneuvering. This includes the area behind,
in front of, and beside the vehicle. Otherwise
you could endanger yourself and/or others.GWarning!
The rear view camera either will not function
or will not function to its full capability if
R the tailgate is open
R it is raining very hard, snowing or foggy
R it is night or you are parking/maneuvering
your vehicle in an area where it is very dark
R the camera is exposed to a very bright white
light
R the immediate surroundings are
illuminated with fluorescent light (the
display may flicker)
R there is a sudden change in temperature,
e.g. if you drive into a heated garage from
the cold (lens condensation)
R the camera lens is dirty or covered
R the rear of your vehicle is damaged
In this case, have the position and setting
of the camera checked by a qualified
specialist workshop. Mercedes-Benz
recommends that you contact a Mercedes-
Benz Center for this purpose.
Do not use the rear view camera in these
situations. Otherwise you could injure
yourself or others and/or damage property
including your vehicle while parking/
maneuvering.
Activating the rear view cameraXMake sure that the SmartKey is in
position 2 in the ignition lock.XMake sure that the "rear view camera"
function is selected in COMAND (see the
