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 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, or if the system is temporarily unus-
■
able
Warning lights and/or warning messages will turn on or flash. (P. 744, 754)
