(Pre-Collision System) - Lexus GS 450h2011 Manual

2-4. Using other driving systems
PCS (Pre-Collision System)
When the radar sensor detects possibility of a frontal collision. Pre-colli-
sion systems such as the brakes and seat belts are automatically engaged
to lessen impact and injuries to occupants as well as vehicle damage.
■ Pre-collision seat belts (front seats only)
If the pre-collision sensor detects that a collision is unavoidable, the pre-
collision 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. 77)
However, the system will not operate in the event of skidding when the
TRAC/VSC systems are disabled.
■
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 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-collision braking can be disabled using the
pre-collision braking off switch.
■ AVS
If the system determines that the collision is unavoidable, the operation of
AVS (P. 212) helps prevent the vehicle front from going down when
hard brakes are applied.
