PCS (Pre-Collision System)

When the radar sensor detects possibility of a frontal collision,
brakes are automatically engaged to lessen impact as well as
vehicle damage.
The alert timing for the pre-collision system can be changed or
turned on/off, as necessary, by operating the switch. (→P. 239)
◆

Pre-collision warning

When a high possibility of a
frontal collision is detected, a
buzzer sounds and a message
is shown on the multi-informa-
tion display to urge the driver to
take evasive action.
◆

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 warning display and buzzer. If the system
determines that a collision is unavoidable, the brakes are automati-
cally applied to reduce the collision speed.
