In such situations, have the vehicle
checked and repaired immediately at a
qualified specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
consult a qualified specialist workshop.
The vehicle is only designed for easily nego-
tiable off-road terrain and poor road surfaces.
When driving off-road, substances such as
sand, mud and water or water mixed with oil
may get into the brakes. This could result in a
reduced braking effect or in total brake failure
and also in increased wear and tear. The brak-
ing characteristics change depending on the
material ingressing the brakes. Clean the
brakes after driving off-road. If you detect a
reduced braking effect or grinding noises,
have the brake system checked in a qualified
specialist workshop as soon as possible.
Adapt your driving style to the different brak-
ing characteristics.
Driving off-road increases the likelihood of
damage to the vehicle, which, in turn, can lead
to failure of the mechanical assembly or sys-
tems. Adapt your driving style to suit the ter-
rain conditions. Drive carefully. Have damage
to the vehicle rectified immediately at a quali-
fied specialist workshop.
Do not switch to transmission position N
when driving off-road. If you try to brake the
vehicle using the service brake, you could
lose control of the vehicle. If the gradient is
too steep for your vehicle, drive back down in
reverse gear.
General notes
H Environmental note
Protection of the environment is of primary
importance. Treat nature with respect.
Observe all prohibiting signs.
Read this section carefully before driving your
vehicle off-road. Off-road driving is only possible with the Off-
Road Engineering package ( Y
page 199).
The following driving systems are specially
adapted for driving over easily negotiable off-
road terrain: R
Off-road program ( Y
page 199) R
Off-road ABS ( Y
page 66) R
Off-road 4ETS ( Y
page 69) R
Off-road ESP ®
( Y
page 72) R
DSR (Downhill Speed Regulation)
( Y
page 197)
Observe the following notes: R
Stop the vehicle before starting to drive
along an off-road route. If necessary, acti-
vate the off-road program ( Y
page 157).R
To avoid damaging the vehicle, make sure
there is always sufficient ground clearance. R
Check that items of luggage and loads are
stowed safely and are well secured
( Y
page 285). R
Always keep the engine running and in gear
when driving on a downhill gradient. Acti-
vate DSR ( Y
page 197). R
Drive slowly and evenly, if necessary at a
walking pace. R
Ensure that the wheels are in contact with
the ground at all times. R
Drive with extreme care on unfamiliar off-
road routes where visibility is poor. For
safety reasons, get out of the vehicle first
and survey the off-road route. R
Check the depth of water before fording
rivers and streams. R
Watch out for obstacles. R
Take care when turning on an uphill or
downhill slope or when driving across a
slope. The vehicle could otherwise tip over. R
Always keep the side windows and the pan-
orama roof with power tilt/sliding panel
closed during the journey. R
Do not deviate from marked routes.
Do not use the HOLD function when driving
off-road, on steep uphill or downhill gradients
or on slippery or loose surfaces. The HOLD Driving tips 181

function cannot hold the vehicle on such sur-
faces.
Checklist before driving off-road X
Engine oil level: check the engine oil level
and add oil if necessary.
When driving on steep gradients, the
engine oil level must be sufficiently high to
ensure a correct oil supply in the vehicle. X
Wheels and tires: check the tire tread
depth and tire pressure. X
Check for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires. X
Replace any missing valve caps. X
Replace dented or damaged wheels. X
Rims: dented or bent rims can result in a
loss of tire pressure and damage the tire
bead. Before driving off-road, check the
wheels and replace them if necessary.
Checklist after driving off-road
! If you detect damage to the vehicle after
driving off-road, have the vehicle checked
immediately at a qualified specialist work-
shop. X
Deactivate off-road program ( Y
page 157).X
Deactivate DSR ( Y
page 197).X
Clean the headlamps and rear lights and
check for damage. X
Clean the front and rear license plates. X
Clean the wheels and tires with a water jet
and remove any foreign objects. X
Clean the wheels, wheel housings and the
vehicle underside with a water jet; check
for any foreign objects and damage. X
Check 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 bel-
lows of the axle joints and propeller shafts. X
After the trip, examine without fail the
entire undercarriage, wheels, tires, brakes, bodywork structure, steering, chassis and
exhaust system for damage. X
After driving in sand, mud, gravel, water or
similar dirty conditions, have the following
checked and cleaned: R
brake discs R
wheels R
brake pads R
axle joints X
If you detect strong vibrations after off-road
travel, check for foreign objects in the
wheels and drive train and remove them if
necessary. Foreign objects can disturb the
balance and cause vibrations.
Driving over poor road surfaces places
greater demands on your vehicle than driving
on normal roads. After driving off-road, check
the vehicle. This allows you to detect damage
promptly and reduce the risk of an accident to
yourself and other road users.
Driving on sand
Observe the following rules when driving on
sand: R
Activate the off-road program
( Y
page 157). R
Avoid high engine speeds. R
Use the left-hand steering wheel paddle
shifter to shift to a lower gear appropriate
to the terrain. R
Drive quickly to overcome the rolling resist-
ance. Otherwise the vehicle's wheels could
become stuck in loose ground. R
Drive in the tracks of other vehicles if pos-
sible. Make sure that: -
the tire ruts are not too deep. -
the sand is sufficiently firm. -
the ground clearance of the vehicle is
sufficient.
Tire ruts and gravel roads
! Check that the ruts are not too deep and
that your vehicle has sufficient clearance.182
