Fault tracing and actions
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. |
