Fault tracing and actions

Fault tracing and actions  - Adaptive Cruise Control (ACC) - Comfort and driving pleasure - Volvo XC60 Owners Manual - Volvo XC60

If the message Radar blocked See manual is displayed, this means that the radar signals from the sensor have been obstructed and that a vehicle ahead cannot be detected.

This, in turn, means that the functions of the ACC, Distance Alert, and Collision Warning System with Auto-brake and Pedestrian Detection will not function.

The table lists possible causes for this message being displayed, and suitable actions.

Cause Action
The surface of the radar in the grille is dirty or obstructed in some way. Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals. No action possible. Heavy precipitation may affect the function of the radar.
Swirling water or snow from the surface of the road may interfere with the radar signals. No action possible. A very wet or snow-covered road surface may affect the function of the radar.
The surface of the radar is clean but the message remains in the display. Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed.
