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 contaminations, 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.

■

Obstacles not detected

The system cannot detect plastic obstacles such as pylons. There may also be occa-

sions when the system cannot detect pedestrians, animals, bicycles, motorcycles,

trees, or snowdrifts.

■

When there is a malfunction in the system

Warning lights and/or warning messages will turn on or flash. (
