Obstacles not detected
■
The sensor cannot detect plastic obstacles such as traffic cones. There may
also be occasions when the sensor cannot detect pedestrians, animals, bicy-
cles, motorcycles, trees, or snowdrifts.
Situations in which the pre-collision system does not function properly
■
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
●
If a vehicle suddenly moves in front of your vehicle, such as at an intersec-
●
tion
If a vehicle suddenly cuts in front of your vehicle, such as when overtaking
●
In inclement weather such as heavy rain, fog, snow or sand storms
●
If the vehicle is skidding when VSC is not operating
●
When an extreme change in vehicle height occurs
●
When only part of your vehicle's front end collides with, or contacts, a vehi-
●
cle or object in a frontal collision
When the radar sensor moves off position due to its surrounding area being
●
subjected to a strong impact
Automatic cancelation of the pre-collision system
■
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-collision system will be
automatically disabled. In this case, the system will not activate even if there
is a collision possibility.
When there is a malfunction in the system
■
The pre-collision system warning light will flash and warning messages will be
displayed. (→P. 564, 579)
