i Cruise control should not be activated
when driving off-road.
Important safety notes
If you fail to adapt your driving style, cruise
control can neither reduce the risk of an acci-
dent nor override the laws of physics. Cruise
control cannot take into account the road,
traffic and weather conditions. Cruise control
is only an aid. You are responsible for the dis-
tance to the vehicle in front, for vehicle speed,
for braking in good time and for staying in
your 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 slippery road surfaces. Braking or accel-
R
erating could 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.

Cruise control is activated. The vehicle
automatically maintains the stored speed.

Cruise control may be unable to maintain
the stored speed on uphill gradients. The
stored speed is resumed when the gradient
evens out. Cruise control maintains the
stored speed on downhill gradients by
automatically applying the brakes.
