■The windshield wiper and washer can be operated when
The “ENGINE START STOP” 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 if the vehicle is traveling above 106 mph
(170 km/h).
■Effects of vehicle speed on wiper operation
Vehicle speed affects the following even when the wipers are not “AUTO” mode.
●Intermittent wiper interval ( mode)
●Wiper operation when the washer is being used (delay until drip prevention
wiper sweep occurs)
With selected, wiper operation will be switched from low speed to intermit-
tent wiper operation only when the vehicle is stationary.
■Rain drop sensor (vehicles equipped with rain-sensing windshield wipers)
●If the wiper switch is turned to the “AUTO” position while the “ENGINE START
STOP” 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 167°F (75°C) or higher, or 14°F
(-10°C) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.
