PCS (Pre-Crash Safety system)

When the radar sensor detects possibility of a frontal collision, the pre-
crash safety system such as the brakes and seat belts are automatically
engaged to lessen impact as well as vehicle damage.

Pre-crash seat belts (front seat belts 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. 110)
However, when the VSC system is disabled, the system will not
operate in the event of skidding.

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.

Pre-crash 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 system determines that a collision is unavoidable, the brakes
are automatically applied to reduce the collision speed. Pre-crash
