Effects of vehicle speed on wiper operation
Vehicle speed affects the following even when the wipers are not in “AUTO”
mode.
●Intermittent wiper interval ( mode)
● Wiper operation when the washer is being used
With low speed mode, wiper operation will be switched from low speed to
intermittent wiper operation only when the vehicle is stationary.

shield wipers)
●If the wiper switch is turned to the “AUTO” position while the “ENGINE
START STOP” switch is in ON mode, the wipers will operate once to
show that “AUTO” mode is activated.
● 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”.
■ 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.
■ Customization that can be co nfigured at Toyota dealer
Settings (e.g. switching operation when the vehicle is stationary) can be
changed. (Customizable features P. 545)
●The sensor judges the amount of rain-
drops.
An optical sensor is adopted. It may not
