■
Obstacles not detected
The sensor cannot detect plastic obstacles such as traffic cones. There may also be occa-
sions 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 your vehicle is steeply inclined
●
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 subjected
to a strong impact
●
When an obstacle suddenly appears in front of the vehicle due to the steering wheel
being turned sharply or another cause
■
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 automatically dis-
abled. 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 temporarily unusable
The pre-crash safety system warning light will flash and warning messages will be dis-
played. (
