Speed control cruise control
Function of cruise control
Cruise control accelerates and brakes the vehi‐
cle automatically in order to maintain a previ‐
ously stored speed.
If you accelerate to overtake, for example, the
stored speed is not deleted. If you remove your
foot from the accelerator pedal after overtaking,
cruise control will resume speed regulation back
to the stored speed.
You can operate cruise control with the cruise
control lever.
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. It 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 vehi‐
cle speed, for braking in good time and for stay‐
ing in your lane.
System limitations
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Do not use cruise control in the following situa‐
tions:
R
In traffic situations which require frequent
changes of speed, e.g. in heavy traffic, on
winding roads.
R
On slippery roads. Accelerating can cause
the drive wheels to lose traction and the
vehicle could then skid.
R
When visibility is poor.
