WARNING■
Lexus Safety System+
The Lexus Safety System+ is designed to
operate under the assumption that the
driver will drive safely, and is designed to
help reduce the impact to the occupants
and the vehicle in the case of a collision
or assist the driver in normal driving con-
ditions.
As there is a limit to the degree of recog-
nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle’s surro undings and driving
safely. Vehicle data recording

using a specialized device. The image recording function can be dis-
abled. However, if the function is disabled,
data from when the pre-collision system
operates will not be available.
Two types of sensors, located behind
the front grille and windshield, detect
information necessary to operate the
drive assist systems.

200 4-5. Using the driving support systems
LS500_OM_OM50F54U_(U) ■
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.204)
