Exceptions for adaptive cruise control
Adaptive cruise control is not available in the following situations:
If one of these exception situations occurs when adaptive cruise control is switched on, adaptive cruise control will be switched off.
A message to this effect will appear on the multi-function display.
Overtake request when adaptive cruise control is active (ACC active)
If adaptive cruise control detects that braking assistance is required on the part of the driver, a warning signal sounds and the warning message "Distance! Please brake!" appears on the multi-function display.
Inadequate braking power during automatic braking by the adaptive cruise control
In this case, the braking power of the adaptive cruise control is not sufficient to prevent a collision.
Traffic situations in which vehicles cannot be reliably detected
The radar sensor for adaptive cruise control scans a narrow, cone-shaped area in front of your vehicle.
Detection can be limited or unreliable, depending on the traffic situation and the size of the vehicle in front. The system may brake too late or unexpectedly. Stationary vehicles are not detected. The system cannot respond to stationary vehicles.
