ADAPTIVE GESCHWINDIGKEITSREGELUNG (ACC):STÖRUNG

If a fault occurs while adaptive cruise control or follow mode is operational, the adaptive cruise control system switches off. The system cannot be used until the fault is cleared. The message centre briefly displays the message DRIVER INTERVENE. The message is then replaced by the message CRUISE NOT AVAILABLE.

If a fault occurs with the adaptive cruise control system, or any related system, at any other time, the system will not be available. The message centre displays the message CRUISE CONTROL NOT AVAILABLE. When the message is displayed, it is not possible to activate adaptive cruise control in any mode.

Accumulations of dirt, snow, or ice on the radar sensor or cover may inhibit adaptive cruise control operation. The fitting of a vehicle front protector or metallised badges may also affect the operation of the system. If this occurs in adaptive cruise control or follow mode, an alarm sounds and the message centre briefly displays DRIVER INTERVENE. The message RADAR SENSOR BLOCKED is then displayed.

The message centre may also temporarily display the message RADAR SENSOR BLOCKED if the radar's vision is disrupted. For example, in poor weather conditions, when travelling through a tunnel, or in complex traffic situations.

NOTES

The same messages may also be displayed while driving on open roads with few objects for the radar to detect.

Clearing an obstruction allows the system to return to normal operation. The adaptive cruise control system can detect obstructions when it’s inactive, e.g. on initial start-up. In these circumstances, the message centre displays the message RADAR SENSOR BLOCKED.

Tyres, other than those recommended for the vehicle, may have different circumferences. Tyres with a different circumference can affect the correct operation of the adaptive cruise control system.
