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 (

page 186).
The following driving systems are specially
adapted for driving over easily negotiable off-
road terrain:

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 186).
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 271).
R Always keep the engine running and in gear
when driving on a downhill gradient. Acti-
vate DSR (
Y
page 184).
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.
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
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. Therefore, check your rims before
driving off-road and replace them as
required.
