4-3. Operating the lights and wipers
■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor (vehicles with ra in-sensing windshield wipers)
● If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 185 °F (85 °C) or higher, or 14° F
(-10° C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is washer fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed.

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 is subject to vibration in AUTO mode. Take care that your fin-
gers, 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

In this case, contact your Toyota dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
