■ The windshield wiper and washer can be operated when
The engine switch is in IGNITION 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 engine switch is in IGNITION ON mode, the wip-
ers will operate 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.
● Raindrop sensor judges the amount of rain-
drops.
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.
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.
