■Raindrop sensor

■If no windshield washer fluid

sprays

●The raindrop sensor judges the

amount of raindrops.

Check that the washer nozzles are

not blocked if there is washer fluid in

the windshield washer fluid reser-

voir.

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

The windshield wipers may oper-

cause low visibility. This may lead

to an accident, resulting in death

or serious injury.

●When the sensor sensitivity ring is

turned toward high while in the

“AUTO” mode, the wipers will

operate once to indicate that the

sensor sensitivity is enhanced.

●If the temperature of the raindrop

sensor is 185°F (85°C) or higher,

or 5°F (-15°C) or lower, the auto-

matic operation may not occur. In

this case, operate the wipers in

any mode other than “AUTO”.
