2-3. Operating the lights and windshield wipers
The windshield wiper and washer can be operated when
The engine switch is in the “ON” position.
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 in “AUTO” mode.
Intermittent wiper interval (“INT” mode)
Wiper operation when the washer is being used (delay until drip prevention
wiper sweep occurs)
With “LO” 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 the rain-sensing windshield wipers)
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the wind-
shield washer fluid reservoir.
In extremely hot or cold weather
The system will turn off if the windshield gets extremely hot (more than 194F
[90C]) or cold (less than 14F [-10C]).
The sensor judges the amount of raindrops.
