lffll __ D_ r_ iv _i_ n-' g"'""'- o_ ff_ r_ o _ a_ d __________________________________________________ _
-Drive only on roads and offroad sections which match
the design of your vehicle and your abilities as a driver .
Never take risks!
Drive slowly and plan ahead!
Take into consideration the
ground clearance of your
vehicle.
- Activate the
ESP offroad mode=:> page 288 as needed.
- Use t he
hill descent control=:> page 289 when driving
down steep sections on hills.
Unpaved roads and offroad
Drive slowly on unfamiliar roads and unknown offroad sections, and
look out for unexpected obstac les (e.g . potholes, rocks, tree stumps,
etc.).
To prevent the vehicle from bottoming and avoid damage to the
underbody, you should drive straight across severe bumps in the
ground with on ly one side of the vehicle so that on ly two of your
whee ls cross the bumps .
Dr ive briskly through sandy or marshy offroad sections and do not
stop, if at all possible.
Driving through water
Your vehicle can drive through standing water if the ground is firm
enough . The
maximum fording depth is 19 .7 in or 500 mm (vehic les
without air springs) or 21.1 in or 535 mm (vehicles with adaptive air
suspension*, at high level 2).
Check the depth of the water before driving through water .
Cross water only at walking speed, do not stop and do not turn the
engine off .
If you drive fast through the water, you wi ll create a bow wave in
front of the vehic le. This bow wave can get into the engine air intake
and severe ly damage the engine. Avoid driving through salt water (corrosion)
.
Driving on a slope
If you ever find yourself not able to climb a slope, do not try to turn
around, drive back down in
reverse. Otherwise, you run the risk of
tipping over.
If the vehicle threatens to tip over when driving across a slope, you
must immediately steer downhill in the direction of the slope.
Do not park your vehicle on steep slopes or grades.
To reduce the risk of tipping over, drive on slopes in the direction of
the downward slope (fall line) -
not crosswise .
Driving on snow-covered ground
The standard tires fitted to your vehicle are not snow tires. So you
should mount wheels with snow tires in good time where winter
road conditions prevail. Before driving on unploughed stretches of
deep snow, install tire chains. For technical reasons, tire chains may
only be installed on the rear whee ls -never on the front wheels .
L1}. WARNING
After driving through water, mud, slush, etc. the brakes may be
slow to take effect because of wet brake rotors and pads . The
brakes must first be carefully dried by braking so that full braking
effect is restored. •
