Off-road driving
Important safety notes
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is
a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
GWARNING
If the vehicle level is high, the vehicle center
of gravity is raised. This could cause the
vehicle to tip over more easily on uphill or
downhill gradients. There is a risk of an
accident.
Select the lowest possible vehicle level.
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
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
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
systems. Adapt your driving style to suit the
terrain conditions. Drive carefully. Have
damage to the vehicle rectified immediately
at a qualified specialist workshop.
Do not switch to transmission positionN
when driving off-road. You could lose control
of the vehicle if you attempt to brake using
the service brake. If the gradient is too steep,
drive backwards in reverse gear.
General notes
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:
ROff-road program 1 and 2 (vehicles with the
ON&OFFROAD package) (Ypage 258)
RLOW RANGE off-road gear (vehicles with
the ON&OFFROAD package)
(Ypage 259)
RDifferential lock (vehicles with the
ON&OFFROAD package) (Ypage 259)
ROff-road ABS (Ypage 68)
RAIRMATIC package (vehicle level)
(Ypage 217)
RDSR (Downhill Speed Regulation)
(Ypage 256)
Observe the following notes:
RStop the vehicle before starting to drive
along an off-road route.
RFor vehicles with the AIRMATIC
package:select a vehicle level that is
suitable for the off-road terrain. To avoid
damaging the vehicle, make sure there is
always sufficient ground clearance.
RCheck that items of luggage and loads are
stowed safely and are well secured
(Ypage 345).
Driving tips197
Driving and parking
Z

RAlways keep the engine running and in gear
when driving on a downhill gradient.
Activate DSR (Ypage 256).
RAlways keep the doors, tailgate, windows
and sliding sunroof closed while driving.
RAdapt your speed to the terrain. The
rougher, steeper or more ruts on the
terrain, the slower your speed should be.
RDrive slowly and at an even speed through
the water. Ensure that a bow wave does not
form as you drive.
RDrive 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.
RLook out for obstacles, such as rocks,
holes, tree stumps and furrows.
RCheck the depth of water before fording
rivers and streams.
RWhen fording, do not stop and do not
switch off the engine.
ROn sand, drive quickly to overcome the
rolling resistance. Otherwise the vehicle's
wheels could become stuck in loose
ground.
RDo not jump with the vehicle as this will
interrupt the vehicle's propulsion.
RAlways keep the engine running and in gear
when driving on a slope.
RDo not shift the automatic transmission to
transmission positionN.
iDo not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients 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
vehicle 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.
XEngine 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.
XDEF tank (BlueTEC vehicles):check the
level and top up if necessary (Ypage 186).
XTire-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.
XWheels and tires:check the tire tread
depth and tire pressure.
XCheck for damage and remove any foreign
objects, e.g. small stones, from the
wheels/tires.
XReplace any missing valve caps.
XReplace dented or damaged wheels.
XRims:dented or bent rims can result in a
loss of tire pressure and damage the tire
bead. Therefore, check your rims before
driving off-road and replace them as
required.
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
workshop.
XVehicles with the ON&OFFROAD
package:activate the on-road program
(Ypage 258).
XDeactivate the LOW RANGE off-road gear
(Ypage 259).
XDeactivate DSR (Ypage 256).
XVehicles with the AIRMATIC package:
lower the vehicle to a ride height suitable
for the road conditions, e.g. to the
highway/high-speed level.
XClean the headlamps and rear lights and
check for damage.
XClean the front and rear license plates.
XClean the wheels/tires with a water jet and
remove any foreign objects.

Radiator
Vehicles with a diesel engine:do not cover
the radiator, for example with a winter front
or bug cover. The readings of the on-board-
diagnostic system may otherwise be
inaccurate. Some of these readings are
required by law and must be accurate at all
times.
Engine oil
General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption
may be higher than this when the vehicle is
new or if you frequently drive at high engine
speeds.
Depending on the engine, the oil dipstick may
be in a different location.
When checking the oil level:
Rpark the vehicle on a level surface.
Rthe engine should be switched off for
approximately five minutes if the engine is
at normal operating temperature.
Rif the engine is not at normal operating
temperature, e.g. if the engine was only
started briefly, wait about 30 minutes
before carrying out the measurement.
