WARNING
●Keep the radar sensors and their sur-
rounding areas on the front bumper
clean at all times.
If a radar sensor or its surrounding area
on the front bumper is dirty or covered
with snow, the system may not operate
and a warning message (
P.436) will
be displayed.
If this occurs, clean off the dirt or snow
and drive the vehicle for approximately

If the warning message does not disap-
pear, have your vehicle inspected by your
Lexus dealer.
●Do not attach accessories, stickers
(including transparen t stickers), alumi-
num tape or other items to the radar
sensors or their surrounding area.
●Do not subject a radar sensor or its
surrounding area on the front bumper
to a strong impact.
If a radar sensor is moved even slightly
off position, the system may malfunction
and vehicles may not be detected cor-
rectly.
In the following situations, have your
vehicle inspected by your Lexus dealer.
• If a radar sensor or its surrounding area is subject to a strong impact
• If the area on the front bumper around a radar sensor is scratched or dented,
or the front bumper has become par-
tially disengaged
●Do not disassemble the radar sensors.
●Do not modify the radar sensors or
their surrounding area on the front
bumper.
●In the following cases, the radar sensor
must be recalibrated. Contact your

injury.
●Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets, snow,
etc., clean the windshield.
• As some glass coating agents may affect the detection performance of
the front camera, consult your Lexus
dealer when using a glass coating
agent.
• If a glass coating agent is applied to the windshield, it will still be necessary to
use the windshield wipers to remove
water droplets, etc. from the area of
the windshield in front of the front
camera.

■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
If the system determines that the possi-
bility of a frontal collision is extremely
high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
PCS (Pre-Collision System)
(vehicles with Lexus Safety
System + A)
The pre-collision system uses a
front radar sensor and front camera
to detect vehicles and pedestri-
ans/bicyclists in front of your vehi-
cle and front side radar sensors to
detect vehicles approaching from
the front left or right side. When the
system determines that the possi-
bility of a frontal collision with a
vehicle or pedestrian/bicyclist is
high, a warning operates to urge
the driver to take evasive action
and the potential brake pressure is
increased to help the driver avoid
the collision. If the system deter-
mines that the possibility of a frontal
collision with a vehicle or pedes-
trian/bicyclist 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.219)

of the function may be canceled if the
accelerator pedal is depressed
strongly or the steering wheel is turned
and the system determines that the
driver is taking evasive action.
• When the active steering assist is operating, if the stee ring wheel is held
firmly or is operated in the opposite
direction to that which the system is
generating torque, the function may be
canceled.
• If the brake pedal is depressed, the sys- tem may determine that the driver is
taking evasive action and the active
steering assist operation may be
delayed.
■Active Asssit for seat belts

seat belts are locked in a retracted posi-
tion, immediately stop the vehicle in a
