PCS (Pre-Collision System)

When the radar sensor detects possibility of a frontal collision, the

pre-collision systems such as the brakes and seat belts are automat-

ically 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 collision occurs.

The same will happen if the driver makes an emergency braking or

loses control of the vehicle. (P. 162)

However, when the VSC system is disabled, the system will not oper-

ate 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

Pre-collision braking

When there is a high possibility of a frontal collision, the system warns

the driver using a warning light, warning display and buzzer. If the sys-

tem determines that a collision is unavoidable, the brakes are automat-

ically applied to reduce the collision speed. Pre-collision braking can be

disabled using the pre-collision braking off switch.
