Driving
RC350/RCF_U (OM24636U)
■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■Dripping prevention wiper sweep
After performing a washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping.
However, this final wiper operation will not be performed while driving.
■Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-
ers)
Vehicle speed affects the following even when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is being used (delay until drip prevention wiper
sweep occurs)
With low speed windshield wiper operation selected, wiper operation will be switched
from low speed to intermittent wiper operat ion only when the vehicle is stationary.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode while the engine switch is in IGNITION ON
mode, the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F (-30°C)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than AUTO mode.
■When the windshield wipers are in tempor ary operation (vehicles with rain-sensing
windshield wipers)
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.
■Operation guide display (vehicles with rain-sensing windshield wipers only)
When the windshield wiper swit ch is operated to activate AUTO mode or when the rain-
sensing level is adjusted, the current status is displayed on the meters for a few seconds.
(  P. 1 0 8 , 1 1 9 )
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is ad opted. 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.

shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.

When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward you and
held continually.
