Adaptive cruise control is linked to other systems such as the stability and traction control system (DSTC). If this system is not functioning properly, adaptive cruise control is automatically deactivated and will go into standby mode.

In the event of automatic deactivation, an audible signal will sound and the message Cruise control Cancelled is shown in the display. The driver must then intervene and adapt the vehicle's speed to the surrounding traffic and regulate the distance to the vehicle ahead.

An automatic switch to standby mode may be caused if:

• the wheels lose traction
• brake temperature is high
• the radar sensor is obstructed by, for example, wet snow or rain.
