Washer/wiper dual oper-
ation
Pulling the lever operates the wip-
ers and washer.
Wipers will automatically operate a
couple of times after the washer
squirts.
(After operating several times, the
wipers operate once more time
after a short delay to prevent drip-
ping. However, the dripping pre-
vention does not operate while the
vehicle is moving.)
■The windshield wiper and washer can be operated when
The power switch is in ON mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washe r fluid in the
windshield washer fluid reservoir.
■ When stopping the hybrid system in an emergency while driving
If the windshield wipers are operating when the hybrid system is stopped, the
windshield wipers will operate in high speed operation. After t he vehicle is
stopped, operation will return to normal when the power switch is turned to
ON mode, or operation will stop when the driver's door is opened.

WARNING
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshie ld becomes
warm. The fluid may freeze on the windshield and cause low visi bility. 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 the washer fluid tank is empty
Damage to the washer fluid pump may be caused if the lever is p ulled
toward you and held continually.
■ When a nozzle becomes blocked
In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

WARNING
■To avoid malfunction of the front camera
Observe the following precautions.
Otherwise, the front camera 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., clean the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces- sary to use the windshield wipers to remove water droplets, etc. from
the area of the windshield in front of the front camera.
• If the inner side of the windshield where the front camera is installed is
dirty, contact your Toyota dealer.
B: Approximately 7.9 in. (20 cm) (Approximately 4.0 in. [10 cm] to the right and left from the center of the front camera)
● If the part of the windshield in front of the front camera is fogged up or cov-
ered with condensation or ice, use the windshield defogger to remove the
fog, condensation or ice. ( P. 370)
● If water droplets cannot be properly removed from the area of t he wind-
shield in front of the front camera by the windshield wipers, replace the
wiper insert or wiper blade.
● Do not attach window tint to the windshield.
● Replace the windshield if it is damaged or cracked.
After replacing the windshield, the front camera must be recali brated. Con-
tact your Toyota dealer for details.
● Do not allow liquids to contact the front camera.
● Do not allow bright lights to shine into the front camera.
● Do not dirty or damage the front camera.
When cleaning the inside of the windshield, do not allow glass cleaner to
contact the lens of the front camera. Also, do not touch the lens.
If the lens is dirty or damaged, contact your Toyota dealer.
● Do not attach objects, such as stickers,
transparent stickers, etc., to the outer
side of the windshield in front of the
front camera (shaded area in the illus-
tration).

WARNING
●Do not subject the front camera to a strong impact.
● Do not change the installation position or direction of the front camera or
remove it.
● Do not disassemble the front camera.
● Do not modify any components of the vehicle around the front ca mera
(inside rear view mirror, etc.) or ceiling.
● Do not attach any accessories to the hood, front grille or front bumper that
may obstruct the front camera. Contact your Toyota dealer for details.
● If a surfboard or other long object is to be mounted on the roo f, make sure
that it will not obstruct the front camera.
● Do not modify the headlights or other lights.

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in
the system.
● In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact your Toyota dealer.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P. 370)
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on
its type, the sunlight reflected from
the surface of the sunshade may
cause the temperature of the front
camera to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera. Close the hood, remove the sticker,
etc. to clear the obstruction.
When “Pre-Collision System Radar
In Self Calibration Unavailable See
Owner’s Manual” is displayedCheck whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

■Enabling/disabling the pre-collision system
The pre-collision system can be enabled/disabled on (4.2-inch
display) or (7-inch display) ( P. 109, 126) of the multi-informa-
tion display.
The system is automatically enabled each time the power switch is
turned to ON mode.
If the system is disabled, the
PCS warning light will turn on
and a message will be dis-
played on the multi-information
display.
■Changing the pre-colli sion warning timing
The pre-collision warn ing timing can be changed on (4.2-inch
display) or (7-inch display) ( P. 109, 126) of the multi-informa-
tion display.
The warning timing setting is retained when the power switch is turned
off. However, if the pre-collision system is disabled and re-en abled, the
operation timing will return to the default setting (middle).
If the pre-collision warning timing is changed, e mergency steering
assist timing will also b e changed accordingly.
If late is selected, emergency st eering assist would not operate in
case of an emergency.

The system detects objects based on
their size, profile, motion, etc. However,
an object may not be detected depending
on the surrounding brightness and the
motion, posture, and angle of the
detected object, preventing the system
from operating properly. (P. 263)

●In some situations such as the following, sufficient braking force or steering
force may not be obtained, preventing the system from performin g properly:
• If the braking functions cannot operate to their full extent, such as when
the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly maintained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)
• When the vehicle is being driven on a gravel road or other sli ppery sur-
face
• When the road surface has deep wheel tracks
• When driving on a hill road
• When driving on a road that has inclines to the left or right
■ If VSC is disabled
●If VSC is disabled ( P. 304), the pre-collision brake assist and pre-collision
braking functions are also disabled.
● The PCS warning light will turn on and “VSC Turned Off Pre-Coll ision Brake
System Unavailable” will be displayed on the multi-information display.
