Adaptive Cruise Control (ACC)
Adaptive cruise control (ACC) can be used on the open road to maintain a constant selected speed between approx. 20 and 100 mph (30 and 160 km/h) without having to use the accelerator pedal. If another vehicle that traveling slower than the selected speed is detected up ahead in the same lane, adaptive cruise control automatically maintains a set distance.
Adaptive cruise control will cause the vehicle to brake if the distance from the vehicle in front becomes too small and to accelerate if the distance increases.
Lack of attention
The increased comfort offered by adaptive cruise control should not induce you to risk your safety. Despite adaptive cruise control, responsibility for maintaining a safe distance, choosing a suitable speed, etc. remains with the driver. The system cannot replace the driver’s attentiveness.
Unsafe traffic situations and unfavorable road conditions
If the prevailing situation does not allow you to drive safely at a sufficient distance and constant speed, adaptive cruise control can cause accidents.
Failure of adaptive cruise control to detect vehicles or objects
Stationary or slow-moving vehicles, pedestrians or objects on the road, oncoming vehicles in the same lane and cross traffic are not detected.
Adaptive cruise control uses a radar sensor located in the center of the front apron (arrow).
For information on car care:
Restricted range of the radar sensor
The range of the radar sensor may be restricted by rain, snow, ice and heavy spray. Vehicles up ahead may not be adequately detected, or may not be detected at all.
