wiper sweep occurs)
When low speed wiper operation is selected, wiper operation will be switched from
low speed to intermittent wiper operation only when the vehicle is stationary.
(However, when the sensor sensitivity is adjusted to the highest, the mode cannot
be switched.)
Sensor sensitivity (high)
Sensor sensitivity (low)
Washer/wiper dual operation
The wipers will automatically
operate a couple of times after
the washer squirts.
(After operating several times,
the wipers operate one more

vent dripping.)
If the headlights are on, the
headlight cleaners will operate
once.

nRaindrop sensor (vehicles with rain-sensing windshield wipers)
lIf the wiper switch is turned to the position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers will operate once to show
that “AUTO” mode is activated.
lWhen 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.
lIf 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”.
nIf no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
CAUTION
nCaution regarding the use of windshield wipers in “AUTO” mode (vehicles 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 or
anything else do not become caught in the windshield wipers.
lThe 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.
