■Rain drop sensor
●If the wiper switch is turned to the “AUTO” position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers will operate once to show

(-15 C) or lower, the automatic operation may not occur. In this case, operate
the wipers in any mode other than “AUTO”.
■Effects of vehicle speed on wiper operation
With the settings other than “AUTO” also, the time until drip prevention wiper
sweep occurs is changed depending on vehicle speed. 
With selected, wiper operation will be switched from low speed to intermit-
tent wiper operation only when the vehicle is stationary. (However, when the sensor
sensitivity is adjusted to the highest level, the mode cannot be switched.)
■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.
