WARNING
■ To avoid malfunction of the front sensor
Observe the following precautions.
Otherwise, the front sensor may not operate properly, possibly leading to an
accident resulting in death or serious injury.
● Keep the windshield clean at all times. If the windshield is dirty or covered
with an oily film, water droplets, snow, etc., clear the windshield. If the
inner side of the windshield in front of the front sensor is dirty, contact any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
● Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the front sensor (shaded area in
the illustration).
A: From the top of the windshield to
approximately 10 cm (4.0 in.) below
the bottom of the front sensor
B: Approximately 20 cm (7.9 in.)
(Approximately 10 cm (4.0 in.) to the
right and left from the center of the
front sensor)
● Do not install or attach anything to the
inner side of the windshield under the
front sensor (shaded area in the illus-
tration).
A: Approximately 10 cm (4.0 in.) (Start-
ing from the bottom of the front sen-
sor)
B: Approximately 20 cm (7.9 in.)
(Approximately 10 cm (4.0 in.) to the

WARNING
● If there is a large difference in temperature between the inside and outside
of the vehicle, such as in winter, t he windshield is likely to fog up easily. If
the part of the windshield in front of the front sensor is fogged up or cov-
ered with condensation or ice, the PCS warning light may illuminate and
the system may be temporarily disabled. In this case, use the windshield
defogger to remove the fog, etc. ( P. 340, 350)
● If the area of the windshield in front of the front sensor is covered with
water droplets, use the windshield wipers to remove them.
If the water droplets are not sufficiently removed, the performance of the
front sensor may be reduced.
● If water droplets cannot be properly removed from the area of the wind-
shield in front of the front sensor by the windshield wipers, replace the
wiper insert or wiper blade.
If the wiper inserts or wiper blades need to be replaced, contact any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
● Do not attach window tinting to the windshield.
● Replace the windshield if it is damaged or cracked.
If the windshield needs to be replaced, contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
● Do not install an antenna in front of the sensor.
● Do not get the front sensor wet.
● Do not allow bright lights to shine into the front sensor.
● Do not dirty or damage the front sensor.
When cleaning the inside of the windshi eld, do not allow glass cleaner to
contact the lens. Also, do not touch the lens.
If the lens is dirty or damaged, contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.

WARNING
● Do not subject the front sensor to a strong impact.
● Do not change the installation position or direction of the front sensor or
remove it.
● Do not disassemble the front sensor.
● Do not install an electronic device or device that emits strong electric
waves near the front sensor.
● Do not modify any components of the vehicle around the front sensor
(inside rear view mirror, sun visors, etc.) or ceiling.
● Do not attach any accessories that may obstruct the front sensor to the
hood, front grille or front bumper. Contact any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional for details.
● If a surfboard or other long object is to be mounted on the roof, make sure
that it will not obstruct the front sensor.
● Do not modify the headlights or other lights.
● Do not attach anything to or place anything on the dashboard.
■ Installation area of front sensor on windshield
When the windshield is fogging up easily, the glass around the front sensor
may be hot due to the heater running. If the glass is touched, it may result in
burns.

PCS (Pre-Collision System)
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
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 colli-
sion with a vehicle 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 colli-
sion with a vehicle is high, the system warns the driver. If the sys-
tem determines that the possibility of a collision is extremely high,
the brakes are automatically applied to help avoid the collision or
reduce the collision speed.
: If equipped
The pre-collision system uses the front sensor to detect vehicles in
front of your vehicle. When the system determines that the possibil-
ity of a frontal collision with a vehicle is high, 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 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 disabled/enabled and the warning tim-
ing can be changed. ( P. 272)
