Blocked sensor

If a message regarding a blocked sensor is displayed, the radar signals from the sensor, located behind a fascia cover near the driver side of the lower grille, have been obstructed. When the radar signals are obstructed, a vehicle ahead cannot be detected and the collision warning system will not function.
The following table lists possible causes and actions for this message being displayed.
