4-5. Using the driving support systems
Conditions that may trigger the system even if there is no danger of a collision
■
In any of the following situations where the frontal area of the radar sensor is inter-
rupted, the radar sensor may detect possibility of a frontal collision and the system
may be activated.
When passing by an oncoming vehicle in a curve or a turn to the right or the left
●
When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,
●
etc.)
When there is a structural object (billboard, low ceiling, fluorescent light, etc.) above
●
the uphill road ahead
When driving on a narrow road or through under a low overhead structure (bridge,
●
tunnel, fly-under, etc.)
When driving on an uneven road surface
●
When there is a metal object, bump, or protrusion on the road surface
●
When vehicle' s front part is raised or lowered depending on loading conditions
●
When the direction of radar sensor is misaligned by strong impact applied on an area
●
around the radar sensor, etc.
When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve
●
When the front of your vehicle is pointing upwards (caused by putting a heavy load in
●
the trunk etc.)
When the system is activated in the situations described above, there is also a possibility
that the brakes may be applied with a force greater than normal.
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-collision 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-collision system
■
When a malfunction occurs due to sensor contamination, 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.
