Forward Collision-Avoidance Assist (FCA) system disabled. Radar blocked

When the sensor cover is blocked with dirt, snow, or debris, the FCA system operation may stop temporarily. If this occurs, a warning message will appear on the LCD display.
Remove any dirt, snow, or debris and clean the radar sensor cover before operating the FCA system. The system will operate normally when such dirt, snow or debris is removed.
The FCA may not properly operate in an area (e.g. open terrain), where any substances are not detected after turning ON the vehicle.
In order for the FCA system to operate properly, always make sure the radar sensor cover is clean and free of dirt, snow, and debris. Dirt, snow, or foreign substances on the lens may adversely affect the sensing performance of the sensor.
