◆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 b rake
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 syste m
determines that a collision is u navoidable, the brakes are auto mati-
cally applied to reduc e the collision speed.
When the radar sensor detects possibility of a frontal collisio n,
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. 238)
