Cruise control

The concept

The system is functional at speeds beginning at
approx. 20 mph/30 km/h.
It maintains the speed that was set using the
control elements on the steering wheel.
The system brakes on downhill gradients if en‐
gine braking action is insufficient.

Unfavorable conditions
Do not use the system if unfavorable con‐

ditions make it impossible to drive at a constant
speed, for instance:

On curvy roads.

In heavy traffic.

On slippery roads, in fog, snow or rain, or on
a loose road surface.

Otherwise, you could lose control of the vehicle
and cause an accident.◀
