■

Raindrop sensor (vehicles with rain-sensing windshield wipers)

●

If the wiper switch is turned to AUTO position while the “START STOP ENGINE”

<“POWER”> switch is in IGNITION ON <ON> mode, the wipers 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 185±F (85±C) or higher, or -22±F

(-30±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 wind-

shield 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.

CAUTION

■

Caution 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.

■

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.
