PCS (Pre-Crash Safety 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-crash warning
When a high possibility of a fron-
tal collision is detected, the pre-
crash safety 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-crash warning can be disabled
using the pre-crash braking off
switch.
Pre-crash seat belts (front seat only)
If the pre-crash sensor detects that a collision is unavoidable, the pre-
crash safety 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. 48)
Pre-crash 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.
