■The windshield wiper and washer can be operated when
The “POWER” switch is in 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 “POWER” switch
is in ON mode, the wipers will operate once to show that “AUTO” mode is acti-
vated.
●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.

●When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle’s line of travel
●When an extreme change in vehicle height occurs
●When there is an abnormality in the radar sensor
●When climbing a steep hill causes an overhead billboard or other metallic struc-
ture to appear directly in the vehicle’s line of travel
When the system is activated in the situations described above there is also a possi-
bility that the seat belts will retract quickly and the brakes will be applied with a force
greater than normal. When the seat belt is locked in the retracted position, stop the
vehicle in a safe place, release the seat belt and refasten.
