■
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
●
When your vehicle is skidding with the VSC system off
●
When an extreme change in vehicle height occurs
●
When the radar sensor moves off position due to its surrounding area being subjected
to a strong impact
●
Due to greatly turning the wheel when an obstacle suddenly appears ahead
■
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.
■
When there is a malfunction in the system, or if the system is temporarily unavailable
The PCS warning light flashes and a warning message is shown on the multi-information
display. If a warning message is shown on the multi-information display, read the message
and follow the instructions.
■
When the TRAC and VSC are turned off
●
When the TRAC and VSC operations are turned off ( → P. 301), the pre-collision brake
assist and pre-collision braking are also turned off. However, the alert function oper-
ates.
●
The PCS warning light turns on and the “VSC Turned Off Pre-Collision Brake System
Unavailable” is shown on the multi-information display.
