Driving WARNING: The collision warning system's brake support can only help reduce the speed at which a collision occurs if the driver applies the vehicle's brakes. The brake pedal must be pressed just like for any typical braking situation. 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. Cause The surface of the radar in the grille is dirty or obstructed in some way The surface of the radar in the grille is clean but the message remains in the display Heavy rain, spray, snow, or fog is interfering with the radar signals Action Clean the grille surface in front of the radar or remove the object causing the obstruction Wait a short time. It may take several minutes for the radar to detect that it is no longer obstructed Do not use the Collision Warning System in these conditions because it may not detect, warn, or respond to potential collisions Do not use the Collision Warning System in these conditions because it may not detect, warn, or respond to potential collisions Swirling water, or snow or ice on the surface of the road may interfere with the radar signals Activating/deactivating collision warning system To turn the warning system and/or chime on or off and set the warning sensitivity , refer to Message center in the Instrument Cluster chapter. 255 2010 MKS (mks) Owners Guide, 2nd Printing USA (fus)
