Forward Collision-Avoidance Assist may operate abnormally or unexpectedly in certain circumstances, including the following:

• The surface of the windscreen is dirty or has damage such as scratches.

• A windscreen whose quality and performance have not been verified is used.

• The forward camera’s field of view is reduced due to window tint film.

• Washer fluid is sprayed continuously or the windscreen wipers are operating.

• It is dark and the tail lamps of the vehicle or motorcycle ahead are off or dim.

• The rear of the vehicle ahead is small or not clearly visible (e.g., when the vehicle ahead is driving at an angle, only the side of the vehicle is visible, or the vehicle is overturned).

• The detected object enters the front blind spot area of a cab-over type vehicle.

• Reflections or shapes projected by moisture or reflective objects on the road are recognised as objects.

• Driving near tunnels or railway bridges.

• The detected object is made of a material that does not reflect well to the front radar.

• There is a low-height or small obstacle ahead.

• A sensor is obscured or damaged.

• The temperature around the front-view camera is extremely high or low.

• The camera lens is obscured by a windscreen tint, film, or coating, damaged glass, or objects on the glass such as a sticker or insect.

• There is moisture or ice on the windscreen.

• Heavy rain, snow, or fog obscures the camera’s view.

• Glare from the sun obstructs the front view camera’s field of view.

• Light reflects off of a wet road surface, such as a puddle.

• There is an object on the instrument panel.

• Your vehicle’s surroundings are excessively bright or dark.

• The light changes suddenly, such as when you enter or exit a tunnel.

• You are in dark conditions and your vehicle’s headlights are not on or are obscured.

• Another vehicle or a motorcyclist, pedestrian, or cyclist is only partially visible.

• The vehicle ahead is a bus, heavy truck, or vehicle with bulky cargo or a trailer.

• The vehicle or motorcyclist ahead does not have tail lights or has an unusual tail light configuration.

• If the ground clearance of the vehicle in front is low or high

• A vehicle, pedestrian, or cyclist suddenly crosses ahead of your vehicle.

• The front radar sensor is damaged or out of position.

• The temperature near the front radar is high or low.

• You are driving in areas where there are few vehicles or structures, such as a desert or meadow.

• You are driving near areas with a lot of metal, such as a construction zone, railroad, or road with metal plates.

• The shadow is on the lane marking by a median strip, trees, guardrail, noise barriers, etc.

• Your view of the vehicle ahead is suddenly obscured.

• The vehicle ahead is detected late.

• The vehicle ahead suddenly becomes obscured by an obstacle and cannot be detected.

• The vehicle ahead is at a significantly angled orientation.

• The vehicle ahead has an unusual shape.

• The vehicle ahead suddenly changes lanes or reduces speed.

• The vehicle ahead is covered in snow.

• You are departing or returning to the lane.

• If your driving is unstable.

• You are driving in a traffic circle and the curvature of the road prevents detection of the vehicle ahead.

• You are driving on a steep hill, which puts the vehicle or motorcyclist ahead out of range of your vehicle’s camera or radar.

The following illustration shows the kinds of images of a vehicle, pedestrian or cyclist that the front view camera and front radar can detect:

The system may not detect a pedestrian or cyclist ahead that is:

• Leaning over or not walking fully upright.

• Wearing clothing or equipment that makes them difficult to detect.

• Moving very quickly ahead of your vehicle.

• Short or crouching.

• Moving opposite of the flow of traffic or having impaired mobility.

• Part of a large crowd ahead of your vehicle.

• Difficult to distinguish from their surroundings.

The system may not detect a pedestrian or cyclist ahead when you are driving:

• Through steam, smoke, or shadow.

• Driving through a tunnel or steel bridge

• In large areas where there are few vehicles or structures, such as a desert, field, or suburban area.

• In a parking lot.

• Through a tollgate, construction area, or rough or bumpy terrain.

• Near areas with a lot of metal, like a construction zone or railroad.

• On a steep or curving road.

• The vehicle moves unstably or shakes severely.

• The vehicle height changes significantly due to abnormal tyre pressure, excessive cargo loading, etc..

• Through a roadside with trees or street lights.

• Along a narrow road with dense trees or overgrowth.

• Through electromagnetic waves, such an area with strong radio waves or electrical noise.

• A snow chain, spare tyre, or wheel of a different size is installed
