Adaptive cruise control* - fault tracing
and action
If the combined instrument panel shows the
message
Radar blocked See manual then it
means that the adaptive cruise control's radar
sensor (p. 213) cannot detect other vehicles
in front of the car.
This message indicates that neither of the
functions for Distance Alert (p. 219) or Colli-
sion Warning with Auto Brake (p. 229) are
working.
The following table presents examples of
possible causes for a message being shown
along with the appropriate action:
Cause Action
The radar surface in the grille is dirty or covered with ice or snow. Clean the radar surface in the grille from dirt, ice and snow.
Heavy rain or snow blocking the radar signals. No action. Sometimes the radar does not work during heavy rain or snowfall.
Water or snow from the road surface swirls up and blocks the
radar signals.
No action. Sometimes the radar does not work on a very wet or snowy road
surface.
The radar surface has been cleaned but the message remains. Wait. It could take several minutes for the radar to sense that it is no longer
blocked.
