
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-crash safety 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

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 vehicle
or object in a frontal collision

When the radar sensor moves off position due to its surrounding area being sub-
jected to a strong impact

Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in the
sensors being unable to detect obstacles, the pre-crash safety system will be auto-
matically disabled. In this case, the system will not activate even if there is a col-
lision possibility.

When there is a malfunction in the system
The pre-crash safety system warning light will flash and warning messages will
be displayed. (
