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.
Filter inspection If the vehicle is operated in the severely air-polluted cities or on dusty rough roads for a long period, it should be inspected more frequently and replaced earlier. When you, the owner, replace the climate control air filter, replace it performing the following procedure, and be careful to avoid damaging other components.
To equalize tread wear, it is recommended that the tires be rotated every 10,000 km (6,500 miles) or 12 months. If irregular wear develops, more frequent tire rotation may be needed. During rotation, check the tires for correct balance. When rotating tires, check for uneven wear and damage.
