4-5. Using the driving support systems

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 (left-hand drive vehicles) or
right-turn (right-hand drive vehicles)

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 the steep angle of the road causes a metal object located beneath the road
surface to be seen ahead of the vehicle

When an extreme change in vehicle height occurs

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 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,
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 vehicle, such as at an intersection

If a vehicle suddenly cuts in front of 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-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.
