Forward Collision-Avoidance Assist operation

Basic function

Warning and control

The basic function for Forward Collision-Avoidance Assist is to warn and control the vehicle depending on the collision level: 'Collision Warning', 'Emergency Braking' and 'Stopping vehicle and ending brake control'.

Collision Warning

  • To warn the driver of a collision, the 'Collision Warning' warning message will appear on the cluster, and an audible warning will sound.

  • If a vehicle is detected in front, the function will operate when your driving speed is between approximately 10~180 km/h (6~112 mph).

  • If a pedestrian or cyclist is detected in front, the function will operate when your driving speed is between approximately 10~85 km/h (6~53 mph).

  • If 'Active Assist' is selected, braking may be assisted.

Emergency Braking

  • To warn the driver that emergency braking will be assisted, the 'Emergency Braking' warning message will appear on the cluster, and an audible warning will sound.

  • If a vehicle is detected in front, the function will operate when your driving speed is between approximately 10~75 km/h (6~47 mph).

  • If a pedestrian or cyclist is detected in front, the function will operate when your driving speed is between approximately 10~65 km/h (6~40 mph).

  • In emergency braking situation, braking is assisted with strong braking power by the function to help prevent collision with the vehicle, pedestrian or cyclist ahead.

Stopping vehicle and ending brake control

  • When the vehicle is stopped due to emergency braking, the 'Drive carefully' warning message will appear on the cluster.

    For your safety, the driver should depress the brake pedal immediately and check the surroundings.

  • Brake control will end after the vehicle is stopped by emergency braking for approximately 2 seconds.

Junction Turning function

Warning and control

Junction Turning function will warn and control the vehicle depending on the collision level: 'Collision Warning', 'Emergency Braking' and 'Stopping vehicle and ending brake control'.

Collision Warning

  • To warn the driver of a collision, the 'Collision Warning' warning message will appear on the cluster, and an audible warning will sound.

  • The function will operate when your driving speed is between approximately 10~30 km/h (6~19 mph) and the oncoming vehicle speed is between approximately 30~70 km/h (19~44 mph).

  • If 'Active Assist' is selected, braking may be assisted.

Emergency Braking

  • To warn the driver that emergency braking will be assisted, the 'Emergency Braking' warning message will appear on the cluster, and an audible warning will sound.

  • The function will operate when your driving speed is between approximately 10~30 km/h (6~19 mph) and the oncoming vehicle speed is between approximately 30~70 km/h (19~44 mph).

  • In emergency braking situation, braking is assisted with strong braking power by the function to help prevent collision with the oncoming vehicle.

Stopping vehicle and ending brake control

  • When the vehicle is stopped due to emergency braking, the 'Drive carefully' warning message will appear on the cluster.

    For your safety, the driver should depress the brake pedal immediately and check the surroundings.

  • Brake control will end after the vehicle is stopped by emergency braking for approximately 2 seconds.

WARNING
  • For your safety, change the Settings after parking the vehicle at a safe location.

  • With 'Active Assist' or 'Warning Only' selected, when ESC is turned off by pressing and holding the ESC OFF button, Forward Collision-Avoidance Assist will turn off automatically. In this case, Forward Collision-Avoidance Assist cannot be set from the Settings menu and the warning light will appear on the cluster which is normal. If ESC is turned on by pressing the ESC OFF button, Forward Collision-Avoidance Assist will maintain the last setting.

  • Forward Collision-Avoidance Assist does not operate in all situations or cannot avoid all collisions.

  • The driver should hold the responsibility to control the vehicle. Do not solely depend on Forward Collision-Avoidance Assist. Rather, maintain a safe braking distance, and if necessary, depress the brake pedal to reduce driving speed or to stop the vehicle.

  • Never deliberately operate Forward Collision-Avoidance Assist on people, animal, objects, etc. It may cause serious injury or death.

  • Forward Collision-Avoidance Assist may not operate if the driver depresses the brake pedal to avoid collision.

  • Depending on the road and driving conditions, Forward Collision-Avoidance Assist may warn the driver late or may not warn the driver.

  • During Forward Collision-Avoidance Assist operation, the vehicle may stop suddenly injuring passengers and shifting loose objects. Always have the seat belt on and keep loose objects secured.

  • If any other function’s warning message is displayed or audible warning is generated, Forward Collision-Avoidance Assist warning message may not be displayed and audible warning may not be generated.

  • You may not hear the warning sound of Forward Collision-Avoidance Assist if the surrounding is noisy.

  • Forward Collision-Avoidance Assist may turn off or may not operate properly or may operate unnecessarily depending on the road conditions and the surroundings.

WARNING
  • Even if there is a problem with Forward Collision-Avoidance Assist, the vehicle's basic braking performance will operate normally.

  • During emergency braking, braking control by Forward Collision-Avoidance Assist will automatically cancel when the driver excessively depresses the accelerator pedal or sharply steers the vehicle.

CAUTION
  • Depending on the condition of the vehicle, pedestrian and cyclist in front and the surroundings, the speed range to operate Forward Collision-Avoidance Assist may reduce. Forward Collision-Avoidance Assist may only warn the driver, or it may not operate.

  • Forward Collision-Avoidance Assist will operate under certain conditions by judging the risk level based on the condition of the oncoming vehicle, driving direction, speed and surroundings.

NOTICE

When a collision is imminent, the Forward Collision-Avoidance Assist may assist the driver with brakes if the driver fails to brake enough.

Forward Collision-Avoidance Assist malfunction and limitations

Forward Collision-Avoidance Assist malfunction

When Forward Collision-Avoidance Assist is not working properly, the 'Check Forward Safety system' warning message will appear, and the and warning lights will appear on the cluster. In this case, have your vehicle inspected by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner.

Forward Collision-Avoidance Assist disabled

When the front windshield where the front view camera is located, front radar cover, bumper or 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 'Forward Safety system disabled. Camera obscured' or the 'Forward Safety system disabled. Radar blocked' warning message, and the and warning lights will appear on the cluster.

Forward Collision-Avoidance Assist will operate normally when snow, rain or foreign matter is removed. Always keep it clean.

If Forward Collision-Avoidance Assist does not operate normally after obstruction (snow, rain, or foreign material) is removed, have your vehicle inspected by a professional workshop. Kia recommends to visit an authorized Kia dealer/service partner.

WARNING
  • Even though the warning message or warning light does not appear on the cluster, Forward Collision-Avoidance Assist may not properly operate.

WARNING
  • Driving on a curved road

    Forward Collision-Avoidance Assist may not detect other vehicle, pedestrian or cyclist in front of you on curved roads adversely affecting the performance of the sensors. This may result in no warning or 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, 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, pedestrian or cyclist in front of you while driving uphill or downhill adversely affecting the performance of the sensors.

    This may result in unnecessary warning or braking assist when necessary.

    Also, vehicle speed may rapidly decrease when a vehicle, 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

    When a vehicle (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 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

    [C]: Same lane vehicle

    When a vehicle (B) in front of you merges out of the lane, Forward Collision-Avoidance Assist may not immediately detect the vehicle (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.

WARNING
  • When you are towing a trailer or another vehicle, we recommend that Forward Collision-Avoidance Assist is turned off due to safety reasons.

  • Forward Collision-Avoidance Assist may operate if objects that are similar in shape or characteristics to vehicle, pedestrian and cyclist are detected.

  • Forward Collision-Avoidance Assist does not operate on bicycles, motorcycles, or smaller wheeled objects, such as luggage bags, shopping carts, or strollers that are dragged by a pedestrian or a cyclist.

  • Forward Collision-Avoidance Assist may not operate normally if interfered by strong electromagnetic waves.

  • Forward Collision-Avoidance Assist may not operate for approximately 15 seconds after the vehicle is started, or the front view camera is initialized.
