2-4. Using other driving systems

When driving
GS_HV_U (OM30C81U)
June 30, 2011 9:20 am
PCS (Pre-Collision System)
∗
∗
:
If equipped
When the radar sensor detects that a frontal collision is highly likely or
even unavoidable, safety 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)
■
Pre-collision brake assist
Applies greater braking force in relation to how strongly the brake pedal is
depressed.
■
Pre-collision 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-collision braking can be dis-
abled using the pre-collision braking off button.
■
AVS
If the system determines that the collision is unavoidable, the operation of
AVS (
→
P. 213) helps prevent the vehicle front from going down when
hard brakes are applied.
