In order for the FCA system to operate properly, always make sure the sensor or 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.
✽ NOTICE

When the sensor is covered or the sensor lens is dirty with foreign substances, such as snow or rain, the FCA system may not be able to detect vehicles or pedestrians. 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 the FCA system to function.
Remove any dirt, snow, or debris and clean the radar sensor cover before operating the FCA system.
The FCA may not properly operate in an area (e.g. open terrain), where any substances are not detected after turning ON the engine.
