- INSPECT CONDITIONS WHEN PRE-COLLISION SYSTEM DID NOT OPERATE
- Check if the problem occurred under any of the following conditions.
Situations in which the pre-collision system may not function properly When driving on roads with sharp bends or uneven surfaces If a vehicle suddenly moves in front of the vehicle, such as at an intersection If a vehicle suddenly cuts in front of the vehicle If the vehicle is skidding When the front part of the vehicle is raised or lowered When the windshield is dirty or covered with raindrops, condensation, ice, snow, etc. When the sensor is misaligned due to a strong impact being applied to the sensor, etc. When a preceding vehicle is a poor reflector of laser (the rear part of the vehicle lowered, very dirty, etc.) When a very bright light, such as the sun or the headlights of oncoming traffic, shines directly into the pre-collision city sensor When driving in inclement weather such as heavy rain, fog, snow or a sand storm When the surrounding area is dark, such as while in a tunnel or during nighttime Result
