■Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper switch is turned to the position while the “POWER” switch is in
ON mode, the wipers will operate once to show that AUTO mode is activated.
■In extremely hot or cold weather (vehicles with rain-sensing windshield wipers)
The system will turn off if the windshield gets extremely hot (more than 194 F
[90 C]) or cold (less than 14 F [-10C]).
If it does not operate, use 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.
CAUTION
■Caution regarding the use of windshield wipers in “AUTO” mode (vehicles with
rain-sensing windshield wipers)
The windshield wipers may operate unexpect edly if the sensor is touched or the
windshield is subject to vibration in “AUTO” mode. Take care that your fingers etc.

raindrops.
An optical sensor is adopted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.
