■The windshield wiper and washer can be operated when 
The power switch is in ON mode.
■Dripping prevention wiper sweep 
After washing and wiping operation several times, the wipers operate one more time 
after a short delay to prevent dripping. 
However, the last sweep will not happen while the vehicle is moving.
■Effects of vehicle speed on wiper operation
●Intermittent windshield wipers interval  changes when the vehicle is stopped.
●With low speed operation selected, wiper operation will be switched from low speed to intermittent operation only when the vehicle is stationary.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If AUTO mode is selected while the power sw itch is in ON mode, the wipers will oper- ate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor  is 85°C (185°F) or higher, or -30°C (-22°F) or lower, automatic operation may not occur. In this case, operate the wip-ers in any mode other than AUTO mode.
■When the windshield wipers are in temporary operation 
AUTO mode cannot be activated even if   is pressed.
■If no windshield washer fluid sprays 
Check that the washer nozzles are not blocked  if there is washer fluid in the windshield washer fluid reservoir.
●The raindrop sensor judges the amount of 
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 thewindshield.
WARNING
■Caution regarding the use of windshield wipers in AUTO mode 
The windshield wipers may operate unexpectedly if the sensor is touched or the wind- shield 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.
