■The windshield wipers and washer can be operated when
The “POWER” switch is in ON mode.
■Effects of vehicle speed on wiper operation (vehicles with rain-sensing wind-
shield wipers)
Even when the wipers are not in AUTO mode, wiper operation varies depending
on vehicle speed when the washer is being used (delay until drip prevention wiper
sweep occurs).
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to the 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 194 °F (90 °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

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.
