Kia Rio: Forward Collision-Avoidance Assist (FCA) system (Radar type) / FCA system front radar sensor

In order for 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.
Warning message and warning light

When the sensor cover is blocked with dirt, snow, or debris, 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
FCA system. The system will operate normally when such foreign substance is removed
FCA system may not properly operate in an area (e.g. open terrain), where any substances
are not detected after turning ON the engine.
✽ NOTICE
- Do not apply foreign objects such as a bumper sticker or a bumper guard
near the radar sensor. Doing so may adversely affect the sensing performance
of the radar.
