NOTICE

For more details on warning messages, refer to More Details.

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

  • 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, motorcycle, 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.

  • When a collision with a surrounding vehicle is expected, Lane-change oncoming, Lane-change side and Evasive steering assist functions will only warn the driver. (if equipped)

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

  • The images or colors may be displayed differently depending on the specifications of the instrument cluster or theme.
