Warning message and warning light
When the sensor is covered or the sensor lens is dirty with foreign substances, such as snow or rain, Forward Collision-Avoidance
Assist operation may stop temporarily.
In this case, a warning message ("Forward Collision-Avoidance Assist (FCA) system disabled. Radar blocked") will appear to notify the driver. Remove the foreign substances to allow Forward Collision-Avoidance Assist to function normally.
Remove any dirt, snow, or debris and clean the radar sensor cover before operating Forward Collision-Avoidance Assist.
Forward Collision-Avoidance Assist may not properly operate in an area (e.g., open terrain), where any vehicles or objects are not detected after turning ON the vehicle.
