Adaptive Cruise Control (ACC)

  1. Vehicles with PDK.

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.

  • Particular attentiveness is required while driving.
  • If the adaptive cruise control deceleration is insufficient, slow the vehicle down immediately using the footbrake.
  • Make sure that you can take control of the vehicle at any time.


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.

  • Do not use adaptive cruise control in heavy traffic, in construction traffic, in urban traffic, on winding stretches of road, or in unfavorable conditions (e.g. wintery conditions, wet roads, varying road surfaces).


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.

  • You should intervene as necessary.
  • Always keep your eyes on the road ahead.

Radar sensor
Adaptive cruise control uses a radar sensor located in the center of the front apron (arrow).

Information

  • Always keep the radar sensor free of dirt, ice and snow to ensure that it is always fully functional.

For information on car care:

  1. Please see chapter "Car Care" on page 70.

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.

  • Do not use adaptive cruise control in such conditions.
