Rules for off-road driving
G
WARNING
If you drive over obstacles or in ruts, the steer-
ing wheel may jerk out of your grip, causing
injury to your hands.
Always hold the steering wheel firmly with
both hands. When driving over obstacles, you
must expect steering forces to increase
briefly and suddenly.
X
Safely stow or secure any items of luggage
or loads.
X
Secure bulk material (e.g. sand or gravel)
with baffle plates or covers to prevent it
slipping.
X
Close side and back windows (
( Y page 61).
X
Before driving off-road, stop the vehicle and
engage a low gear.
X
If necessary, activate the differential locks
( Y page 190).
X
Activate the ABS off-road program
( Y page 164).
Vehicles with Telligent

selected:
G
WARNING
If the engine revs drop below the minimum
engine speed, the electronics automatically
disengage the clutch. This interrupts the
transmission of power. The vehicle may, for
example, roll backwards on gradients. There
is a risk of an accident.
Never let the engine revs drop below the min-
imum engine speed.
All vehicles:
! Only engage the differential locks if there
is equal traction on all wheels. You could
otherwise damage the differential locks.

X Challenging driving conditions, vehi-
cles with Telligent
shift: activate manual drive program
( Y page 177).
Undesired interruptions to the tractive
power that may occur with automatic gear
shifting are avoided.
X Difficult terrain, vehicles with Telli-
®
gent automatic gearshift: manually
shift between gears. Fold out the clutch
pedal ( Y page 181).
X
All vehicles: only drive off-road with the
engine running and a gear engaged.
X
Drive slowly and smoothly. Walking pace is
necessary in many situations.
X
Do not declutch or change gear on hills.
X
Always ensure that the wheels remain in
contact with the ground.
X
Exercise the utmost caution when driving
across unfamiliar, unpredictable terrain.
For reasons of safety, first get out of the
vehicle and inspect the terrain.
X
Watch out for obstacles such as rocks,
holes, tree stumps and ruts.
X
Do not deviate from marked tracks or
paths.
Do not shift into neutral while driving on
mountainous terrain or declutch. You could
lose control of the vehicle while trying to
brake with the service brake only. If your vehi-
cle is not able to cope with the gradient, drive
backwards in reverse gear.
Driving on inclines
G
WARNING
If you drive up a steep incline at an angle or
turn on a steep incline, the vehicle could slip
sideways, tip and overturn. There is a risk of
an accident.
When driving up an incline, drive into the line
of fall (upwards or downwards in a straight
line) and do not turn.
