HANDLING PRECAUTION

Precautions for Forward Collision Warning

INFOID:0000000006223678

FORWARD COLLISION WARNING (FCW)

• FCW system is intended to warn the driver before a collision but will not avoid a collision. It is the drive's

responsibility to stay alert, drive safely and be in control of the vehicle at all times.

• As there is a performance limit, the FCW system may not provide a warning in certain conditions.
• The FCW system will not detect the following objects.
- Pedestrians, animals, or obstacles in the roadway.
- Oncoming vehicles in the same lane
• FCW system will not detect under the following conditions.
- When the sensor gets dirty, it is impossible to detect the distance from the vehicle ahead.
- When driving into a strong light (i.e. sunlight)
• The sensor generally detects signals returned from the reflectors on a vehicle ahead. Therefore, the FCW

system may not warn properly under the following conditions:

- When the reflectors of the vehicle ahead are positioned high or close to each other (including a small vehicle

such as motorcycles).

- When the sensor gets dirty or it is impossible to detect the distance to the vehicle ahead.
- When the reflectors on the vehicle ahead is missing, damaged or covered.
- When the reflector of the vehicle ahead is covered with dirt, snow or road spray.
- When visibility is low (such as rain, fog, snow, etc.).
- When snow or road spray from traveling vehicles are splashed.
- When dense exhaust or other smoke (black smoke) from vehicles reduces the visibility of the sensor.
- When excessively heavy baggage is loaded in the rear seat or the luggage room of own vehicle.
- When abruptly accelerating or decelerating.
- On steep downhill or roads with sharp curves.
- When there is a highly reflective object near the vehicle ahead.

i.e.) very close to other vehicle, signboard, etc.

- When own vehicle are towing a trailer.
• Depending on certain road conditions (curved, beginning of a curve), vehicle conditions (steering position,

vehicle position), or preceding vehicle's conditions (position in lane, etc.), the FCW system may not function
properly. The FCW system may detect highly reflective objects such as reflectors, signs, white markers, and
other stationary objects on the road or near the traveling lane, and provide unnecessary warning. 

• The FCW system may not function in offset conditions.
• The FCW system may not function when the distance to the vehicle ahead is extremely close.
• The FCW system is designed to automatically check the sensor's functionality. If the sensor is covered with

ice, a transparent or translucent plastic bag, etc., the system may not detect them. In these instances the
FCW system may not be able to warn properly. Be sure to check and clean the sensor regularly.

• Excessive noise will interfere with the warning chime sound, and the chime may not be heard.
• A sudden appearance of the vehicle in front (i.e.: when a vehicle abruptly cuts in) may not be detected and

the system may not warn soon enough.

• The FCW system will be canceled automatically with a chime sound and the IBA OFF indicator light will illu-

minate under the following conditions:

- When the sensor window is dirty
- When the FCW system malfunctions
