ÿ Operating conditions
When the power switch is in ON mode
ÿ Anti-drip operation
The washer fluid sprays the wipers several times, then one more time to prevent dripping. However, the anti-drip
operation does not work while driving.
ÿ Effect of vehicle speed on operation
The vehicle speed affects the intermittent wiper operation time.
ÿRaindrop detection sensor (vehicles equipped with raindrop detection wipers)
•The raindrop detection sensor determines the amount of raindrops.
Since it uses an optical sensor, it may not work properly if
the front window glass is intermittently exposed to the
morning sun or the setting sun, or if it is soiled by insects,
etc.
•If the power switch is set to AUTO mode while the power switch is in ON mode, the wipers will operate once to
check operation.
•When the sensitivity adjustment of the raindrop sensor is adjusted to the (high) side in AUTO mode, the wiper
operates once to check the operation.
•When the temperature of the raindrop detection sensor is 90°C or higher or -15°C or lower, AUTO may not
operate. In that case, use the wiper in other than AUTO mode.
ÿ When washer fluid does not come out
If the washer fluid does not come out even though the washer fluid level is not insufficient, check the nozzle for
clogging.
