Forward Collision-Avoidance Assist operation

Warning and control

The basic function for Forward Collision-Avoidance Assist is to warn and control the vehicle depending on the collision risk level: ‘Collision warning!’, ‘Emergency braking’ and ‘Stopping vehicle and ending brake control’.

Collision warning!

Except CUV
For CUV

  • To warn the driver of a collision, the ‘Collision warning!’ warning message will appear on the cluster, an audible warning will sound and the steering wheel will vibrate.

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

  • If ‘Active assist’ is selected, braking may be assisted.

Emergency braking

Except CUV
For CUV

  • To warn the driver that emergency braking will be assisted, the ‘Emergency braking’ warning message will appear on the cluster, an audible warning will sound and the steering wheel will vibrate.

  • If a vehicle is detected in front, the function will operate when your vehicle speed is between approximately 10~85 km/h (6~53 mph) (except CUV), 10~80 km (6~50 mph) (for CUV). Depending on the condition of the vehicle ahead and the environment surrounding it, the possible maximum operating speed may be reduced.

  • If a pedestrian or cyclist is detected in front, the function will operate when your vehicle speed is between approximately 10~65 km/h (6~40 mph) (except CUV), 10~80 km (6~50 mph) (for CUV). Depending on the condition of pedestrians and cyclists and the environment surrounding it, the possible maximum operating speed may be reduced.

  • 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.

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 illuminate 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, 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.

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

  • 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. The function may only warn the driver, or the function may not operate.

  • It operates only under certain conditions by judging the danger according to a condition of the oncoming vehicle, driving direction, speed and the surrounding environment.

NOTICE

  • In a situation collision is imminent, braking may be assisted by Forward Collision-Avoidance Assist when braking is insufficient by the driver.

  • Depending on the instrument cluster specifications or theme, images or colours may be displayed differently.
