PCS (Pre-Crash Safety)

When the radar sensor detects possibility of a frontal collision, the
pre-crash safety system such as the brakes and seat belts help to be
automatically engaged to lessen impact as well as vehicle damage.
■

Pre-crash seat belts (front seats 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. 98)
However, when the VSC system is disabled, the system will not oper-
ate 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.

Radar sensor

When traveling on a road with very light traffic and very little to reflect the
radar waves emitted by the radar sensor, the system may decide that the
radar sensor is dirty, even if the sensor is not actually dirty. The system will
automatically restore itself when reflected radar waves are detected.

and determines whether a colli-
