Off-road driving
Important safety notes G
WARNING
Do not load items on the basic carrier bars. It
may cause instability during some maneuvers which could result in an accident.
Drive slowly in unknown terrain. This will
make it easier to recognize unexpected obsta-
cles and avoid damage to the vehicle.
To help avoid the vehicle rolling over, never
turn it around on steep inclines. If the vehicle cannot complete the attempted climb, back it
down in reverse gear.
Do not drive along the side of a slope. The
vehicle might otherwise rollover. If in doing so
the vehicle begins to show a tendency to roll,
immediately steer into a line of gravity
(straight up or downhill).
Never let the vehicle roll backwards in idle.
You may lose control of the vehicle if you use only the service brake. For information on
driving downhill, see "Driving downhill".
When driving off-road, sand, mud and water,
possibly mixed with oil, for example, could 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 braking char- acteristics change depending on the material
ingressing the brakes. Clean the brakes after driving off-road. If you detect a reduced brak- ing effect or grinding noises, have the brake
system checked in a qualified specialist work- shop as soon as possible. Adapt your driving
style to the different braking 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. 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. Practice by driving over more gentle off-road terrain first.
Familiarize yourself with the characteristics
of your vehicle and the gear shift operation
before driving through difficult terrain.
The following driving systems are specially
adapted to off-road driving:
R 4ETS (Y page 63)
R Transfer case (Y page 186)
R Differential locks (Y page 188)
Observe the following notes:
R stop your vehicle and, if necessary, shift the
transfer case to LOW RANGE(Ypage 186)
before driving off-road.
R AMG vehicles: the ECO start/stop func-
tion is not available in transfer case posi-
tion LOW RANGE (Ypage 136).
R engage the differential locks, if necessary
(Y page 189).
i ABS, 4ETS, ESP ®
and BAS are deactivated
while the differential locks are engaged.
This allows the front wheels to lock briefly,
so that these can dig into a loose surface.
However, please note that locked wheels
skid and can no longer steer.
R Check that items of luggage and loads are
stowed safely and are well secured
(Y page 253).
R To avoid damaging the vehicle, make sure
there is always sufficient ground clearance.
R Always keep the engine running and in gear
when driving on a downhill gradient.
R Always keep the engine running and in gear
when driving on a slope.
R Drive slowly and evenly, if necessary at a
walking pace. 158
Driving tipsDriving and parking

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 When fording, do not stop and do not
switch off the engine.
R Look out for obstacles, such as rocks,
holes, tree stumps and furrows.
R Always keep the doors, rear door, side win-
dows and the sliding sunroof closed while
the vehicle is in motion.
R Switch off cruise control.
R Do not stray from marked routes or paths.
R Adapt your speed to the terrain. The
rougher, steeper or more ruts on the ter-
rain, the slower your speed should be.
R Drive slowly and at an even speed through
the water. Ensure that a bow wave does not form as you drive.
R On sand, drive quickly to overcome the roll-
ing resistance. Otherwise the vehicle's
wheels could become stuck in loose
ground.
R Do not jump with the vehicle as this will
interrupt the vehicle's propulsion.
R Avoid high engine speeds. Drive at appro-
priate engine speeds (maximum
3,000 rpm).
R Do not shift the automatic transmission to
transmission position N.
R Always check the vehicle for damage after
off-road driving.
i Information about retrofitting special all-
terrain tires is available from any qualified
specialist workshop.
i Do not use the HOLD function when driv-
ing off-road, on steep uphill or downhill gra- dients or on slippery or loose surfaces. The
HOLD function cannot hold the vehicle on
such surfaces. Checklist before driving off-road !
If the engine oil warning lamp lights up
while the vehicle is in motion, stop the vehi- cle in a safe place as soon as possible.
Check the engine oil level. The engine oil
warning lamp warning must not be ignored.
Continuing the journey while the symbol is
displayed could lead to engine damage.
X Oil level: check the engine oil level and add
oil if necessary.
Only then does the engine receive enough
oil when the vehicle is on a steep incline.
X Tire-changing tool kit: check that the jack
is working and make sure you have the lug
wrench, a robust tow cable and a folding
spade 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 Carry a sound spare wheel.
Checklist after driving off-road Driving over rough terrain places greater
demands on your vehicle than driving on nor-
mal 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.
X Shift the transfer case to HIGH
RANGE(Y page 186).
X Disengage the differential locks
(Y page 190).
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. Driving
