192 2-3. Operating the lights and windshield wipers
■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.
■ Rain drop sensor (vehicles equipped with the raindrop detection wind-
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
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.

Maintenance and care
CAUTION
■
When cleaning the windshield (veh icles equipped with the raindrop
detection windshield wipers)
Make sure to turn off the wiper switch.
If the switch is left in the “AUTO” position, the windshield wiper may operate
unexpectedly in the following situations. Failure to turn off the wiper switch
may possibly result in hands being caught or other serious injuries and
cause damage to the windshield wiper.
● When the upper part of the windshield where the raindrop sensor is
located is touched by hand
● When a wet rag or similar is held close to the raindrop sensor
● If something bumps against the windshield
● If you directly touch the sensor body or if something bumps into the sensor
■ Caution about the exhaust pipe
Exhaust gasses cause the exhaust pipe to become quite hot.
When washing the vehicle, be careful not to touch the pipe until it has cooled
sufficiently, as touching a hot exhaust pipe can cause burns.
