Forward Collision-Avoidance Assist Operation

Basic function

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

Collision Warning

2C_FCABasicCollisionWarningInfo

  • To warn the driver of a collision, Forward Safety warning light (O) blinking, the "Collision Warning" warning message will appear on the cluster, an audible warning will sound, and the steering wheel will vibrate.

  • If a vehicle or powered two-wheeler is detected in front, the function will operate when your vehicle speed is between about 6-124 mph (10-200 km/h).

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

Emergency Braking

2C_FCABasicEmergencyBrakingInfo

To warn the driver that emergency braking will be assisted, Forward Safety warning light (O) blinking, the "Emergency Braking" warning message will appear on the cluster, an audible warning will sound, and the steering wheel will vibrate.

Emergency Braking will operate under the following conditions:

  • Vehicle or powered two-wheeler:

    Driving Vehicle

    Stopped Vehicle

    Weak braking power

    About 6-124 mph (10-200 km/h)

    Strong braking power

    About 6-80 mph (10-130 km/h)

    About 6-47 mph (10-75 km/h)

    About 6-62 mph (10-100 km/h)*1

    If Forward Collision-Avoidance Assist judges that avoiding a collision is difficult even by changing the driving lane, braking is assisted more earlier. (if equipped)

  • Pedestrian or cyclist:

    The function will operate when your vehicle speed is between about 6-40 mph (10-65 km/h).

The function operation range may decrease due to the front traffic condition or the surroundings of the vehicle.

When driving at night, the powered two-wheeler recognition performance is degraded, so Forward Collision-Avoidance Assist may be temporarily limited or may not work.

  • The function will operate when your vehicle speed is between about 40-47 mph (65-75 km/h).

  • The pedestrian or cyclist moves in the same direction as your vehicle, or in the opposite direction. In addition, there is sufficient space for an evasive movement for your vehicle. However, this function may not operate for pedestrians or cyclists moving in the horizontal direction.

  • The steering wheel may turn automatically when emergency steering is operating.

  • Emergency steering will automatically cancel when risk factors disappear. If necessary, the driver must steer the vehicle.

  • Emergency steering may not operate or may cancel during operation if the steering wheel is held tight or steered in the opposite direction.

  • When steering is assisted to avoid collision with a vehicle, powered two-wheeler, pedestrian and cyclist, Evasive steering assist will be cancelled if collisions with other objects (vehicles, powered two-wheeler, pedestrians, or cyclists) are expected.

  • Evasive steering assist may not operate if space to avoid collision in the driving lane is insufficient.

  • When driving at night, the detecting performance of powered two-wheeler may decrease and temporarily limit or disable Front Collision-Avoidance Assist.

For more information on warning messages, refer to Collision Warning in "Forward Collision-Avoidance Assist Operation" section in this chapter.

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

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

  • The driver has 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.

  • 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 system's warning message appears 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.

  • Depending on the condition of the vehicle, powered two-wheeler, pedestrian, or 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.

  • Only Forward Collision-Avoidance Assist warning and collision mitigation are possible depending on the detectable distance.

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

  • The images and colors in the instrument cluster may differ depending on the instrument cluster type or theme selected from the settings menu.
