■The windshield wiper and washer can be operated when
Vehicles without a smart entry & start system
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system
The engine switch is in IGNITION ON mode.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield 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 “AUTO” position while the engine switch is
in IGNITION ON mode, the wiper will operate once to show that “AUTO”
mode is activated.
● If the temperature of the raindrop sensor is 90C (194F) or higher, or -15C
(5 F) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
■ 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
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.
