The concept

The system is functional at speeds beginning at approx. 20 mph/30 km/h.

The speed specified using the lever on the steering column is maintained.

The system brakes on downhill gradients if engine braking action is insufficient.

Do not use the system if unfavorable conditions Do not use cruise control
Do not use the system if unfavorable conditions 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.◀
