PCS (Pre-Collision System)


: If equipped
When the radar sensor detects possibility of a frontal collision, the
pre-collision system such as the brakes and seat belts are auto-
matically engaged to lessen impact as well as vehicle damage.
■
Pre-collision seat belts (front seat belts only)
If the pre-collision sensor detects that a collision is unavoidable,
the pre-collision system will retract the seat belt before the colli-
sion occurs. The same will happen if the driver makes an emer-
gency braking or loses control of the vehicle. (

P. 132)
However, when the VSC system is disabled, the system will not
operate in the event of skidding.
■
Pre-collision brake assist
When there is a high possibility of a frontal collision, the system
applies greater braking force in relation to how strongly the
brake pedal is depressed.
■
Pre-collision braking
When there is a high possibility of a frontal collision, the system
warns the driver using a warning light and buzzer. If the system
determines that a collision is unavoidable, the brakes are auto-
matically applied to reduce the collision speed. Pre-collision
braking can be disabled using the pre-collision braking off
switch.
