Forward Collision-Avoidance Assist may not operate normally, or it may operate unexpectedly under the following circumstances:

• A sensor or the its surroundings are contaminated or damaged

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

• The camera lens is obscured by a tinted, filmed or coated windshield, by damaged glass, or by foreign material (sticker, bug, etc.) on the glass

• There is moisture or ice on the windshield

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

• The field of view of the front-view camera is obstructed by sun glare

• Light is reflected off a wet road surface, such as a puddle in the road

• An object is placed on the instrument panel

• The surroundings are very bright (e.g., glare) or very dark (e.g., in a tunnel).

• The light changes suddenly, (e.g., when entering or exiting a tunnel)

• Dark conditions, when the headlamps are not on or are obscured, or the other vehicle has no taillights

• Only part of the vehicle, powered two-wheeler, pedestrian or cyclist is detected

• The vehicle in front is a bus, heavy truck, truck with an unusually shaped cargo, trailer, etc.

• The vehicle or powered two-wheeler in front has no taillights or its, taillights are in unusual positions

• The rear of the front vehicle is small or the vehicle does not look normal, such as when the vehicle is tilted or overturned Clarify

• The other vehicle's ground clearance is extremely low or high

• A vehicle, powered two-wheeler, pedestrian or cyclist suddenly cuts in front

• The front radar or its surroundings are is impacted, damaged, or out of position

• The temperature around the front radar is high or low

• The temperature of the front radar is extremely high or low

• Driving in areas where there are few vehicles or structures (for example, desert, meadow, etc.)

• Driving near areas containing metal substances, such as a construction zone, railroad, metal plates on the road.

• A material is near that reflects very well on the front radar, such as a guardrail, nearby vehicle.

• The cyclist in front is on a bicycle made of material that does not reflect on the front radar's signal

• The vehicle or powered two-wheeler appears suddenly

• The view of the vehicle or powered two-wheeler is suddenly blocked

• The vehicle or powered two-wheeler in front suddenly changes a lane or suddenly reduces speed

• The vehicle in front is covered with snow

• You are departing or returning to the lane

• Unstable driving

• You are on a roundabout and the vehicle or powered two-wheeler in front is not detected

• You are continuously driving in a circle

• The vehicle or powered two-wheeler in front has an unusual shape

• The vehicle or powered two-wheeler in front is on a steep hill, out of range of the camera and radar

  The illustration above shows the kinds of images that the front-view camera and front radar are capable of detecting as a vehicle, powered two-wheeler, pedestrian and cyclist. The system may not detect a pedestrian or cyclist that is:

• leaning over or is not fully walking upright

• The pedestrian or cyclist is wearing clothing or equipment that makes it difficult to detect

• The pedestrian or cyclist in front is moving very quickly

• The pedestrian or cyclist in front is short or is posing a low posture

• The pedestrian or cyclist in front has impaired mobility or moving intersected with the driving direction

• There is a group of pedestrians, cyclists or a large crowd in front

• The pedestrian or cyclist is wearing clothing that easily blends into the background, making it difficult to detect

• The pedestrian or cyclist is difficult to distinguish from the similarly shaped structure in the surroundings

• You are driving by a pedestrian, cyclist, traffic signs, structures, etc., near the intersection

• When driving in the following places

  • Driving through steam, smoke, or shadow

  • Driving through a tunnel or iron bridge

  • Driving in large areas where there are few vehicles or structures (i.e., desert, meadow, suburb, etc.)

  • Driving in a car park

  • Driving through tollgate, construction areas, partially paved roads, bumpy roads, speed bumps, etc.

  • Driving near areas containing metal substances, such as a construction zone, railroad, etc.

  • Driving on an inclined road, curved road, etc.

  • Driving through a roadside with trees or street lights

  • Driving through a narrow road where trees or grass are overgrown

  • There is interference by electromagnetic waves, such as driving in an area with strong radio waves or electrical noise
