In order for FCA system to operate properly, always make sure the sensor cover or sensor 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 operation may temporarily stop. In this case, the warning message appears to warn the driver.
This is not a malfunction with FCA. To operate FCA again, remove the foreign substances.
FCA may not properly operate in an area (e.g. open terrain), where any substances are not detected after turning ON the vehicle.
WARNING
FCA system may not activate without any warning messeges according to driving condition, traffic on the road, weather, road condition, etc.
NOTICE
In an urgent situation, the braking system enters into the ready status for prompt reaction to assist the driver in depressing the brake pedal. FCA provides additional braking power for optimum braking performance, when the driver depresses the brake pedal during FCA operation.
When FCA is not working properly, the FCA warning light () will illuminate and the warning message will appear for a few seconds. After the message disappears, the master warning light () will illuminate.
Park your car at the side of the road so that you can work with the TMK away from moving traffic. Place your warning triangle in a prominent place to make passing vehicles aware of your location. To be sure your vehicle will not move, even when you're on fairly level ground, always set your parking brake.
If the high mounted stop lamp (LED) (1), does not operate, have your vehicle checked by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner. The LED lamps cannot be replaced as a single unit because it is an integrated unit.
