■ 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, 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 inter-
section
●
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
●
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 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
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, or if the system is tempo-
rarily unusable
Warning lights and/or warning messages will turn on or flash. (
