Limitations of the system
The Forward Collision avoidance assist (FCA) system is designed to monitor the vehicle ahead or a pedestrian or cyclist (if equipped) in the roadway through radar signals and camera recognition to warn the driver that a collision is imminent, and if necessary, apply emergency braking.
In certain situations, the radar sensor or the camera may not be able to detect the vehicle, pedestrian or cyclist (if equipped) ahead. In these cases, the FCA system may not operate normally. The driver must pay careful attention in the following situations where the FCA operation may be limited.
Detecting vehicles
The sensor may be limited when:
-
The radar sensor or camera is obstructed with a foreign object or debris
-
The camera lens is obscured due to tinted, filmed or coated windshield, damaged glass, or residue of foreign objects (sticker, bug, etc.) on the glass
-
Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera
-
There is interference by electromagnetic waves
-
There is severe irregular reflection from the radar sensor
-
The radar/camera sensor recognition is limited
-
The vehicle in front is too small to be detected (for example a motorcycle etc.)
-
The vehicle in front is an oversize vehicle or trailer that is too big to be detected by the camera recognition system (for example a tractor trailer, etc.)
-
The camera's field of view is not well illuminated (either too dark or too much reflection or too much backlight that obscures the field of view)
-
The vehicle in front does not have their rear lights or their rear lights does not turned ON or their rear lights are located unusually.
-
The outside brightness changes suddenly, for example when entering or exiting a tunnel
-
When light coming from a street light or an oncoming vehicle is reflected on a wet road surface such as a puddle in the road
-
The field of view in front is obstructed by sun glare or head light of oncoming vehicle.
-
The windshield glass is fogged up; a clear view of the road is obstructed
-
The vehicle in front is driving erratically
-
The vehicle is on unpaved or uneven rough surfaces, or road with sudden gradient changes.
-
The vehicle is driven near areas containing metal objects as a construction zone, railroad, etc.
-
The vehicle drives inside a building, such as a basement parking lot
-
The camera does not recognize the entire vehicle in front.
-
The camera is damaged.
-
The brightness outside is too low such as when the headlamps are not on at night or the vehicle is going through a tunnel.
-
The shadow is on the road by a median strip, trees, etc.
-
The vehicle drives through a tollgate.
-
The rear part of the vehicle in front is not normally visible. (the vehicle turns in other direction or the vehicle is overturned.)
-
The sensor is pointed too high or too low when passing over a speed bump
-
The vehicle in front is moving perpendicular to the driving direction
-
The vehicle in front is stopped perpendicular to traffic
-
The vehicle in front is driving towards your vehicle or reversing
-
You are on a roundabout and the vehicle in front is outside the viewing range



-
Driving on a curve
The performance of Forward Collision-Avoidance Assist system may be limited when driving on a curved road.
The front camera or radar sensor recognition system may not detect the vehicle, pedestrian or cyclist traveling in front on a curved road.
This may result in no alarm and braking when necessary.
Always pay attention to road and driving conditions, and if necessary, depress the brake pedal to reduce your driving speed in order to maintain a safe distance.



Forward Collision-Avoidance Assist system may recognize a vehicle, pedestrian or cyclist in the next lane or outside the lane when driving on a curved road.
If this occurs, the system may unnecessarily alarm the driver and apply the brake.
Always pay attention to road and driving conditions, while driving.



-
Driving on a slope
The performance of Forward Collision-Avoidance Assist system may be decreased while driving upward or downward on a slope. The front camera or front radar sensor recognition may not detect the vehicle, pedestrian or cyclist in front.
This may result in unnecessary alarm and braking or no alarm and braking when necessary.
When the system suddenly recognizes the vehicle, pedestrian or cyclist in front while passing over a slope, you may experience sharp deceleration.
Always keep your eyes forward while driving upward or downward on a slope, and, if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.

-
Changing lanes
When a vehicle changes lanes in front of you, the FCA system may not immediately detect the vehicle, especially if the vehicle changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

When driving in stop-and-go traffic, and a stopped vehicle in front of you switches out of your lane, the FCA system may not immediately detect the next vehicle ahead of you in your lane of travel. In this case, you must maintain a safe braking distance, and if necessary, press the brake pedal to reduce your driving speed in order to maintain a safe distance.

-
Detecting the vehicle in front of you
When the vehicle in front has heavy loading extended rearward, or when the vehicle in front has higher ground clearance, it may induce a hazardous situation. Always pay attention to road and driving conditions, while driving and, if necessary, depress the brake pedal to reduce your driving speed in order to maintain distance.
Detecting pedestrians or cyclists (if equipped)
The sensor may be limited when:
-
The pedestrian or cyclist is not fully detected by the camera recognition system, for example, if the pedestrian is leaning over or is not fully walking upright
-
The pedestrian or cyclist is moving very quickly or appears abruptly in the camera detection area
-
The pedestrian or cyclist is wearing clothing that easily blends into the background, making it difficult to be detected by the camera recognition system
-
The outside lighting is too bright (e.g. when driving in bright sunlight or in sun glare) or too dark (e.g. when driving on a dark rural road at night)
-
It is difficult to detect and distinguish the pedestrian or cyclist from other objects in the surroundings, for example, when there is a group of pedestrians, cyclists or a large crowd
-
There is an item similar in shape or appearance to a person
-
The pedestrian or cyclist is below the sensor's viewing range
-
The sensor can not identify the pedestrian's outline because of other items changing their profile, such as mobility assistance devices
-
The radar sensor or camera is obstructed by a foreign object or debris
-
Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera
-
When light coming from a street light or an oncoming vehicle is reflected on a wet road surface such as a puddle in the road
-
The field of view in front is obstructed by sun glare
-
The windshield glass is fogged up; a clear view of the road is obstructed
-
The adverse road conditions cause excessive vehicle vibrations while driving
-
When the pedestrian or cyclist suddenly enters the path of travel of the vehicle
-
When the cyclist in front is riding perpendicular to the direction of travel
-
When there is any electromagnetic interference
-
When the cyclist is near areas containing metal objects such as a construction zone, railroad, etc.
-
If the bicycle material is not reflected well on the radar

In some instances, the FCA system may be cancelled when subjected to electromagnetic interference.

-
Do not use the Forward Collision avoidance Assist (FCA) system when towing a vehicle. Application of the FCA system while towing may adversely affect the safety of your vehicle or the towing vehicle.
-
Use extreme caution when the vehicle in front of you has cargo that extends rearward from the cab, or when the vehicle in front of you has higher ground clearance.
-
The FCA system is designed to detect and monitor the vehicle ahead or detect a pedestrian or cyclist (if equipped) in the roadway through radar signals and camera recognition. It may not always detect bicycles, motorcycles, or smaller wheeled objects such as luggage bags, shopping carts, or strollers.
-
Never try to test the operation of the FCA system. Doing so may cause severe injury or death.
-
If the front bumper, front glass, radar or camera have been replaced or repaired, have the vehicle inspected by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner.
