2464-3. Operating the lights and wipers
HIGHLANDER_U (OM0E031U)
■The windshield wiper and washer can be operated when
Vehicles without a smart key system
The engine switch is in the “ON” position.
Vehicles with a smart key system
The engine switch is in IGNITION ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing win dshield
wipers)
After performing a washing and wiping operation several times, the wipers
operate one more time after a short delay to prevent dripping.
However, this final wiper operation will not be performed while driving.
■ Effects of vehicle speed on wip er operation (vehicles with rain-sensing
windshield wipers)
Even when the wipers are not in “AUTO” mode, wiper operation va ries
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.
● When the sensor sensitivity ring is turned toward high while in “AUTO”
mode, the wipers will operate once to indicate that the sensor sensitivity is
enhanced.
● If the temperature of the raindrop sensor is 194 F (90 C) or higher, or 5 F
(-15 C) or lower, automatic operation may not occur. In this case, o perate
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 washe r 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.
