g
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.
■
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, bicycles, motorcy-
cles, 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 intersection
●
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
●
When your vehicle is skidding with the VSC system off
●
When an extreme change in vehicle height occurs
●
When only part of your vehicle’s front end collides with, or contacts, a vehicle or
object in a frontal collision
●
When the axis of the radar is out of adjustment
■
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 automati-
cally disabled. In this case, the system will not activate even if there is a collision pos-
sibility.
■
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (
