4-3. Operating the lights and wipers

■

The windshield wiper and washer can be operated when



Vehicles without a smart key system

The engine switch is in the “ON” position.



Vehicles with a smart key system

The engine switch is in IGNITION ON mode.

■

Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After performing a washing and wiping operation several times, the wipers
operate one more time after a short delay to prevent dripping.

However, this final wiper operation will not be performed while driving.

■

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.

●

When the sensor sensitivity ring is turned toward high while in “AUTO”
mode, the wipers will operate once to indicate that the sensor sensitivity is
enhanced.

●

If the temperature of the raindrop sensor is 194

°F (90°C) or higher, or 5°F

(-15

°C) 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 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.

■

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 the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.

■

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.
