■ Windshield wiper features
The rear window and outside rear view mirror defoggers automatically turn on
when you operate the wipers.
WARNING
■ Caution regarding the use of windshield wipers in “AUTO” mode
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers or anything else do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
■ When a nozzle becomes blocked
In this case, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Do not try to clean it with a pin or other object. The nozzle will be damaged.

The front sensor is located on the
upper side of the windshield. It
consists of 2 types of sensors,
each of which detects information
necessary to operate the drive
assist systems.
Laser sensors
Monocular camera sensor
Front sensor

WARNING
■ Front sensor
The front sensor uses lasers to detect vehicles ahead of your vehicle. The
front sensor is classified as class 1M laser product according to the
IEC 60825-1 standard. Under normal usage conditions, these lasers are not
harmful to the naked eye. However, it is necessary to observe the following
precautions.
Failure to do so may result in the loss of eyesight or severe visual impair-
ment.
● To avoid hazardous laser radiation exposure, never attempt to disassem-
ble the front sensor (e.g. remove the lenses). When disassembled, the
front sensor is classified as a class 3B laser product according to the
IEC 60825-1 standard. Class 3B lasers are hazardous and pose a risk of
eye injury under direct exposure.
● Do not attempt to look into the front sensor with a magnifying glass, micro-
scope or other optical instrument within a distance of less than 100 mm
(3.9 in.).

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 retailer or Toyota authorized repairer, or any reliable
repairer.
● 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. 394, 401)
●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.) (Approx-
imately 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 illustra-
tion).
A: Approximately 10 cm (4.0 in.) (Start-
ing from 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)

WARNING
●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 retailer or Toyota authorized repairer, or any reliable repairer.
● 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
retailer or Toyota authorized repairer, or any reliable repairer.
● 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 retailer or
Toyota authorized repairer, or any reliable repairer.
● 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. C ontact any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer for details.

PCS (Pre-Crash Safety system)
◆Pre-crash 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-crash 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-crash 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-crash safety system uses the front sensor to detect
vehicles in front of your vehicle. When the system determines
that the possibility of a frontal collision with a vehicle 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 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-crash safety system can be disabled/enabled and the warn-
ing timing can be changed. (P. 262)

■ Situations in which the system may not operate properly
● In some situations such as the following, a vehicle may not be detected by
the front sensor, preventing the system from operating properly:
• If an oncoming vehicle is approaching your vehicle
• When approaching the side or front of a vehicle
• If a preceding vehicle has a small rear end, such as an unloaded truck
• If a vehicle ahead is carrying a load which protrudes past its rear bumper
• If a vehicle ahead is irregularly shaped, such as a tractor or side car
• If the sun or other light is shining directly on a vehicle ahead
• If a vehicle ahead makes an abrupt maneuver (such as sudden swerving,
acceleration or deceleration)
• When suddenly cutting behind a preceding vehicle
• If a preceding vehicle has a low rear
end, such as a low bed trailer
• If a vehicle ahead has extremely high
ground clearance
• If a vehicle cuts in front of your vehicle
or emerges from beside a vehicle
