■The windshield wiper and washer can be operated when
Vehicles without a smart entry & start system
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system
The engine switch is in IGNITION ON mode.
■Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Even when the wipers are not in “AUTO” mode, wiper operation varies
depending on vehicle speed when the washer is being used (delay until drip
prevention wiper sweep occurs).
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” position while the engine switch is
in IGNITION ON mode, the wiper will operate once to show that “AUTO”
mode is activated.
●If the temperature of the raindrop sensor is 90C (194F) or higher, or -15C
(5F) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.

●The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

WARNING
■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.
■Caution regarding the use of windshield wipers in “AUTO” mode (vehi-
cles with rain-sensing windshield wipers)
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 etc. do not become caught in the windshield wipers.
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 dealer or repairer, or another
duly qualified and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

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

right and left from the center of the front sensor)
●If there is a large difference in temperature between the inside and outside
of the vehicle, such as in winter, the 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. 406, 413)
●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.
●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
