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.
