Driving
■ Pedestrian alert
When the system determines that
there is a possibility of a frontal collision
with a stationary or moving pedestrian
in front of your vehicle, a message will
be displayed on the head-up display to
warn the driver.
■ Pre-collision warning
When the system determines that the
possibility of a frontal collision is high, a
buzzer will sound and a warning mes-
sage will be displayed on the
multi-information display to urge the
driver to take evasive action.
■ Pre-collision brake assist
When the system determines that the
possibility of a frontal collision is high,
the system applies greater braking
force in relation to how strongly the
brake pedal is depressed.
■ Pre-collision braking
When the system determines that the
possibility of a frontal collision is high,
the system warns the driver. If the sys-
tem determines that the possibility of a
frontal collision is extremely high, the
brakes are automatically applied to
help avoid the collision or reduce the
collision speed.
PCS (Pre-Collision System)
(vehicles with Lexus Safety
System+A)
The pre-collision system uses a
front radar sensor and camera sen-
sor to detect vehicles and pedestri-
ans in front of your vehicle and front
side sensors to detect vehicles
approaching from the front left or
right side. When the system deter-
mines that the possibility of a frontal
collision with a vehicle or pedes-
trian is high, a warning operates to
urge the driver to take evasive
action and the potential brake pres-
sure is increased to help the driver
avoid the collision. If the system
determines that the possibility of a
frontal collision with a vehicle or
pedestrian is extremely high, the
brakes are automatically applied to
help avoid the collision or help
reduce the impact of the collision.
The pre-collision system can be dis-
abled/enabled and the warning tim-
ing can be changed. (→P.213)
