Driving
IS200t_EE(OM53D19E)
■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 85°C (185°F) or higher, or -30°C (-22°F)
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.
●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 the
windshield.
