Forward Collision-Avoidance Assist malfunction and limitations
Forward Collision-Avoidance Assist malfunction
When Forward Collision-Avoidance Assist is not working properly, the warning message will appear, and the Forward Safety warning light () and the Master warning light () will appear on the cluster. Kia recommends visiting an authorized Kia dealer/service partner.
Forward Collision-Avoidance Assist disabled
When the front windshield where the front view camera is located, sensor is covered with foreign material, such as snow or rain, it can reduce the detecting performance and temporarily limit or disable Forward Collision-Avoidance Assist.
If this occurs the warning message, and the Forward Safety warning light () and the Master warning light () will appear on the cluster.
Forward Collision-Avoidance Assist will operate properly when snow, rain or foreign material is removed.
If Forward Collision-Avoidance Assist does not operate properly after obstruction (snow, rain, or foreign material) is removed, Kia recommends visiting an authorized Kia dealer/service partner.
-
Even though the warning message or warning light does not appear on the cluster, Forward Collision-Avoidance Assist may not properly operate.
-
Forward Collision-Avoidance Assist may not properly operate in an area (for example, open terrain), where any objects are not detected after turning ON the vehicle.
-
Even if restarting the vehicle with the sensors blocked or malfunctioned, Forward Collision-Avoidance Assist may not properly operate as the function maintains the last setting.

-
The vehicle or powered two-wheeler in front is driving uphill or downhill
-
The pedestrian or cyclist is not fully detected, for example, if the pedestrian is leaning over or is not fully walking upright
-
The pedestrian or cyclist is wearing clothing or equipment that makes it difficult to detect
The illustration above shows the image the front view camera and front radar are capable of detecting as a vehicle, powered two-wheeler, pedestrian and cyclist.
-
The pedestrian or cyclist in front is moving very quickly
-
The pedestrian or cyclist in front is short or is posing a low posture
-
The pedestrian or cyclist in front has impaired mobility or moving intersected with the driving direction
-
There is a group of pedestrians, cyclists or a large crowd in front
-
The pedestrian or cyclist is wearing clothing that easily blends into the background, making it difficult to detect
-
The pedestrian or cyclist is difficult to distinguish from the similarly shaped structure in the surroundings
-
You are driving by a pedestrian, cyclist, traffic signs, structures, etc., near the intersection
-
When driving in the following places
-
Driving through steam, smoke or shadow
-
Driving through a tunnel or iron bridge
-
Driving in large areas where there are few vehicles or structures (i.e. desert, meadow, suburb, etc.)
-
Driving in a parking lot
-

-
Your vehicle height is low or high due to heavy loads, abnormal tire pressure, etc.
-
Driving on a curved road
Forward Collision-Avoidance Assist may not detect other vehicle, powered two-wheeler, pedestrians or cyclists in front of you when driving on curved roads adversely affecting the performance of the sensors. This may result in no warning, braking assist when necessary.
When driving on a curve, you must maintain a safe braking distance, and if necessary, steer the vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.
Forward Collision-Avoidance Assist may detect a vehicle, powered two-wheeler, pedestrian or cyclist in the next lane or outside the lane when driving on a curved road.
If this occurs, Forward Collision-Avoidance Assist may unnecessarily warn the driver and control the brake. Always check the traffic conditions around the vehicle.
-
Driving on an inclined road
Forward Collision-Avoidance Assist may not detect other vehicle, powered two-wheeler, pedestrians or cyclists in front of you while driving uphill or downhill, adversely affecting the performance of the sensors.
This may result in unnecessary warning, braking assist or no warning, braking assist when necessary.
Also, vehicle speed may rapidly decrease when a vehicle, powered two-wheeler, pedestrian or cyclist ahead is suddenly detected.
Always have your eyes on the road while driving uphill or downhill and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.
-
Changing lanes
[A]: Your vehicle,
[B]: Lane changing vehicle or powered two-wheeler
When a vehicle or powered two-wheeler (B) moves into your lane from an adjacent lane, it cannot be detected by the sensor until it is in the sensor's detection range.
Forward Collision-Avoidance Assist may not immediately detect the vehicle when the vehicle or powered two-wheeler (B) changes lanes abruptly. In this case, you must maintain a safe braking distance, and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.
[A]: Your vehicle,
[B]: Lane changing vehicle or powered two-wheeler
[C]: Same lane vehicle or powered two-wheeler
When a vehicle or powered two-wheeler (B) in front of you merges out of the lane, Forward Collision-Avoidance Assist may not immediately detect the vehicle or powered two-wheeler (C) that is now in front of you. In this case, you must maintain a safe braking distance, and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain a safe distance.
-
Detecting vehicle
If 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, additional special attention is required. Forward Collision-Avoidance Assist may not be able to detect the cargo extending from the vehicle. In these instances, you must maintain a safe braking distance from the rearmost object, and if necessary, steer your vehicle and depress the brake pedal to reduce your driving speed in order to maintain distance.
-
When you are towing a trailer or another vehicle, turn off Forward Collision-Avoidance Assist for safety reasons.
-
Forward Collision-Avoidance Assist may operate if objects that are similar in shape or characteristics to vehicles, powered two-wheelers, pedestrians and cyclists are detected.
-
Forward Collision-Avoidance Assist does not operate on bicycles, or smaller wheeled objects, such as luggage bags, shopping carts, or strollers.
-
Forward Collision-Avoidance Assist may not operate properly if interfered by strong electromagnetic waves.
-
Forward Collision-Avoidance Assist may not operate for 15 seconds after the vehicle is started, or the front view camera is initialized.
