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 mes-
sage 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.
