Hyundai Elantra: Forward Collision–Avoidance Assist (FCA) (sensor fusion) / Function operation

Basic function

Function warning and control

The basic function for Forward Collision- Avoidance Assist is to help 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 system will operate when your vehicle speed is between approximately 6~112 mph (10~180 km/h).
  • If a pedestrian or cyclist is detected in front, the system will operate when your vehicle speed is between approximately 6~53 mph (10~85 km/h).
  • 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 system will operate when your vehicle speed is between approximately 6~47 mph (10~75 km/h).
  • If a pedestrian or cyclist is detected in front, the system will operate when your vehicle speed is between approximately 6~40 mph (10~65 km/h).
  • In emergency braking situation, braking is assisted with strong braking power by the system 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

Function warning and control

Junction Turning function will help 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 vehicle speed is between approximately 6~19 mph (10~30 km/h) and the oncoming vehicle speed is between approximately 19~44 mph (30~70 km/h).
  • 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 system will operate when your vehicle speed is between approximately 6~19 mph (10~30 km/h) and the oncoming vehicle speed is between approximately 19~44 mph (30~70 km/h).
  • In emergency braking situation, braking is assisted with strong braking power by the system to help prevent collision with the oncoming vehicle.

Information

If the driver's seat is on the left side, Junction Turning function will operate only when the driver turns left. If the driver's seat position is on right side, the function will operate only when you turn right.

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

Take the following precautions when using Forward Collision-Avoidance Assist:

  • 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 for more than 3 seconds, Forward Collision-Avoidance Assist will turn off automatically. In this case, the function 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, 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 the function will automatically cancel when the driver excessively depresses the accelerator pedal or sharply steers the vehicle.

CAUTION

  • Forward Collision-Avoidance Assist operating speed range may reduce due to the conditions of the vehicle or pedestrian in front or surroundings. Depending on the speed, the system may only warn the driver, or the system 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.

Information

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