Conditions that may trigger the system even if there is no danger of a collision
●
When there is an object by the roadside at the entrance to a curve
●
When passing an oncoming vehicle on a curve
●
When driving over a narrow iron bridge
●
When there is a metal object on the road surface
●
When driving on an uneven road surface
●
When passing an oncoming vehicle on a left-turn
●
When your vehicle rapidly closes on the vehicle in front
●
When a grade separation/interchange, sign, billboard, or other structure appears
to be directly in the vehicle’s line of travel
●
When climbing a steep hill causes an overhead billboard or other metallic structure
to appear directly in the vehicle’s line of travel
When the system is activated in the situations described above, there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten it.

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.
