-
The detection range of the front corner and rear corner radars is based on the normal road width of ordinary roads. On narrow roads, warnings may be triggered by a vehicle or powered two-wheeler driving in the next lane. Conversely, on wide roads, radars may fail to recognise a vehicle or powered two-wheeler driving in the next lane and not issue warnings.
-
The lateral approaching vehicle response function is deactivated in the following situations:

-
If Forward Collision-Avoidance Assist is activated
-
-
After the lateral approaching vehicle response function has been triggered or after changing lanes, be sure to move into the centre of the lane. If you continue to drive along the edge of the lane without moving to the lane's centre, the lateral approaching vehicle response function will be deactivated.
-
If an additional accident is expected due to emergency steering, only a collision warning will be issued to notify of the danger.

-
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, pedestrian, cyclist and two-wheeler, Evasive steering assist will be cancelled if collisions with other objects (vehicle, 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 performance of powered two-wheeler recognition is decreased, so the Forward Collision-Avoidance Assist system may be temporarily limited or may not work.
For more details on warning messages, refer to More Details.
-
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.
-
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.
-
Adjust the volume in the vehicle properly and always pay attention.
-
The Forward Collision Assist could stop, not operate, or unnecessarily operate the function, depending on road conditions, surroundings and driving conditions. Always pay attention to your surroundings and be prepared for potential collisions/dangerous situations.
-
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.
-
The surroundings and pedestrians, cyclists and powered two-wheeler or other vehicles in front of you may affect the speed or detection range to operate Forward Collision-Avoidance Assist, resulting in Forward Collision-Avoidance Assist temporarily limited or disabled.
-
Forward collision avoidance assistance operates under specific conditions, taking into account the status of the oncoming vehicle, powered two-wheeler and cyclist, driving direction, speed, and surrounding environment to judges the level of risk.
-
The function may be limited or deactivated in cases where the driving speed is excessively high or there is a significant speed difference between the vehicle and the oncoming powered two-wheelers or cyclists.
-
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)
-
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 colours may be displayed differently depending on the specifications of the instrument cluster or theme.
