PCS (Pre-Collision System)

When the sensor detects that a frontal collision is highly likely or even

unavoidable, safety systems such as the brakes and seat belts are auto-

matically engaged to help avoid a collision or to lessen impact as well as

vehicle damage.

Pre-collision warning

When a high possibility of a fron-

tal collision is detected, the pre-

collision system warning light

flashes, a buzzer sounds and a

message is shown on the multi-

information display to urge the

driver to take evasive action.

Pre-collision warning can be dis-

abled using the pre-collision brak-

ing off switch.

Pre-collision seat belts (front seat 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. 40)

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
