■Handling the radar sensor
One Blind Spot Monitor sensor is installed inside the left and right side of the vehicle
rear bumper respectively. Observe the follow ing to ensure the Blind Spot Monitor can
function correctly.
●Do not subject the sensor or surrounding area on the bumper to a strong impact. If
the sensor moves even slight ly off position, the system may malfunction and vehicles
that enter the detection area may not be detected. If the sensor or surrounding area is
subject to a strong impact, always have the area inspected by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor or surrounding area on the
bumper.
●Do not modify the sensor or su rrounding area on the bumper.
●Do not paint the rear bumper any colo r other than an official Lexus color.

PCS (Pre-Collision system)∗
◆Pre-collision seat belts (front seat belts only)
If the system detects that a collision is
unavoidable, the system will retract the
seat belt before the collision occurs.
The same will happen if the driver makes an emergency braking or loses c\
on-
trol of the vehicle. (→ P. 31)
However, when the VSC system is disabl ed, the system will not operate in the
event of skidding.
◆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 high possibility of a frontal collision, the system warns the
driver using a warning light , warning display and buzzer. If the system deter-
mines that a collision is unavoidable, the brakes are automatically applied to
reduce the collision speed. Pre-collisio n braking can be disabled using the
pre-collision braking off switch.
◆AVS (Adaptive Variable Suspension System) control (if equipped)
When the system determines that there is a high possibility of a frontal colli-
sion, the AVS optimizes the damping effect ( →P. 341)
∗: If equipped
When the radar sensor detects possibilit y of a frontal collision, the pre-colli-
sion system such as the brakes and se at belts are automatically engaged to
lessen impact as well as vehicle damage.

◆Driver monitor system (if equipped)
When the system determines that there is a possibility of a collision with the
vehicle in front, and the driver is not facing forward, PCS warnings are given in
advance to warn the driver. If the driv er continues to not be facing forward,
and a high possibility of a collision with the vehicle in front is detected, PCS
informs the driver of high possibility of a collision with the vehicle in front by
performing slight braking to provide a physical warning (pre-collision alert
braking).

■Automatic cancelation of pre-collision system
When a malfunction occurs due to sensor contaminations, etc. that results in the sensors
being unable to detect obstac
les, the pre-collision system will be automatically disabled.
In this case, the system will not activate even if there is a collision possibility.
■Obstacles not detected
The system cannot detect plastic obstacles su ch as pylons. There may also be occasions
when the system cannot detect pedestrians, animals, bicycles, motorcycles, trees, or
snowdrifts.
■Conditions that may trigger th e system even if there is no possibility of a collision
In any of the following situations where the frontal area of the radar sensor is interrupted,
the radar sensor may de tect possibility of a frontal collis ion and the system may be acti-
vated.
●When passing by an oncoming vehicle in a curve or a turn to the right or the left
●When rapidly approaching an obstacle ahead (e.g. preceding vehicle, toll gate barrier,
etc.)
●When there is a structural object (billboar d, low ceiling, fluorescent light, etc.) above
the uphill road ahead
●When driving on a narrow road or throug h under a low overhead structure (bridge,
tunnel, fly-under, etc.)
●When driving on an uneven road surface
●When there is a metal object, bump, or protrusion on the road surface
●When vehicle’s front part is raised or lowered depending on loading conditions
●When the direction of radar sensor is misa ligned by strong impact applied on an area
around the radar sensor, etc.
●When there is an obstacle (guard rail, etc.) by the roadside at the entrance to a curve
●When the front of your vehicle is pointing upwards (caused by towing a trailer, during
emergency towing or putting a heavy lo ad in the luggage compartment etc.)
When the system is activated in the situations described above, there is also a possibility
that the seat belts w ill retract quickly and the brakes ma y be applied with a force greater
than normal. When the seat belt is locked in the restricted position, stop the vehicle in a
safe place, release the seat belt and refasten it.
■When there is a malfunction in the system, or if the system is temporarily unusable
Warning lights will turn on or flash, and warning messages will be displayed.

CAUTION
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary in any of the following situations.
●When water or snow thrown up by the surrounding vehicles hinders the functioning
of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the luggage com-
partment etc.)
●Vehicles that cut in suddenly
●Vehicles with small rear ends (tra ilers with no load on board etc.)
●Motorcycles traveling in the same lane
■Handling the radar sensor
Observe the following to ensure the pre-collision system can function effectively:
●Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or dam-
age them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even s lightly off position, the system may become inaccurate or
malfunction. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by your Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding area.
●Do not modify or paint the sensor and grille cover.
●If the sensor needs to be replaced, contact your Lexus dealer.

■Handling the driver monitor sensor (v
ehicles with driver monitor sensor)
Observe the following to ensure the driver monitor sensor can function effectively.
Failure to do so may result in a malfunct ion or may prevent the system from correctly
determining the direction the driver is facing, resulting in an unexpected accident.
●Do not disassemble, damage, lift or pull on the sensor.
●Do not touch the sensor while driving.
●Do not wet or spill water on the sensor.
●Do not drop anything on or allow anything to hit against the sensor. Do not subject the
sensor to an impact.
●Make sure that there are no sc ratches, dirt or stickers on the side of the sensor that
faces the driver.
●Do not place any objects in front of the si de of the sensor that faces the driver or
cover the sensor.
■Determining the direction the driver is faci ng (vehicles with driver monitor sensor)
The direction the driver is facing may not be determined correctly if the following con-
ditions exist:
●There is an object between the driver monitor sensor and the driver’s face, such as
when the sensor is blocked.
●A part of the driver ’s face is covered.
●The sensor or the driver’s face is expo sed to intense light such as sunlight.
●The driving posture is improper.
NOTICE
■Precautions for cleaning the driver monitor sensor (vehicles with driver monitor sen-
sor)
●Gently wipe the sensor with a soft cloth to prevent damage.
●Wipe any excess dirt with a cloth dampened with neutral detergent, all liquids having
been wrung out of the cloth. After that, wipe again with a dry cloth.
●Do not use benzene, thinner, glass cleaners, wax, etc.
