Off-road ABS is activated when the off-road
program is selected.
At speeds below 30 km/h the front wheels
lock cyclically during braking. The digging-in
effect achieved in the process reduces the
stopping distance when driving off-road. The
steerability of the vehicle is considerably
reduced if the wheels lock.

Cruise control
General notes
Cruise control maintains a constant road speed
for you. It brakes automatically in order to avoid
exceeding the set speed. You must select a
lower gear in good time on long and steep down-
hill gradients, especially if the vehicle is laden or
towing a trailer. By doing so, you will make use of
the braking effect of the engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
Use cruise control only if road and traffic con-
ditions are appropriate for maintaining a steady
speed for a prolonged period. You can store any
road speed above 30 km/h.
Important safety notes
If you fail to adapt your driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account road, weather or traffic
conditions. Cruise control is only an aid. You are
responsible for the distance to the vehicle in
front, for vehicle speed, for braking in good time,
and for staying in lane.
Do not use cruise control:
in road and traffic conditions which do not
R
allow you to maintain a constant speed (e.g. in
heavy traffic or on winding roads)
on smooth or slippery roads. Braking or accel-
R
erating can cause the drive wheels to lose
traction and the vehicle could then skid
when there is poor visibility, e.g. due to fog,
R
heavy rain or snow
If there is a change of drivers, advise the new
driver of the speed stored.
