4-5. Using the driving support systems
■ Automatic cancelation of 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 automatically disabled.
In this case, the system will not activate even if there is a collision possibility.
■ Obstacles not detected
The system cannot detect plastic obstacles such as pylons. There may also be occasions
when the system cannot detect pedestrians, animals, bicycles, motorcycles, trees, or
snowdrifts.
■ Conditions that may trigger the system even if there is no possibility 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 (nose up, nose down)
● 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 a billboard or other metallic structure appears to be in the direct line of travel
due to driving on a hill
● When there are excessive changes in the vehicle height (when it tilts forwards or back-
wards)
● When the axis of the radar is out of adjustment
● When passing through certain toll gates
● When passing through an overpass
● When passing through a tunnel
When the system is activated in the situations described above, there is also a possibility
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 restricted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■ When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights will turn on or flash, and warning messages will be displayed.
