■The windshield wiper and washer can be operated when
The engine switch is in IGNITION ON mode.
■Dripping prevention wiper sweep
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 wiper operation (vehicles with rain-sensing windshield wip-
ers)
Vehicle speed affects the following even when the wipers are not in AUTO mode.
●Intermittent wiper interval
●Wiper operation when the washer is being used (delay until drip prevention wiper
sweep occurs)
With low speed windshield wi per operation selected, wiper operation will be switched
from low speed to intermittent wiper operation only when the vehicle is stationary.
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper is turned to AUTO mode wh ile the engine switch is in IGNITION ON
mode, the wipers will operate once to show that AUTO mode is activated.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F (-30°C)
or lower, automatic operation may not occur. In this case, operate the wipers in any
mode other than AUTO mode.
■When the windshield wipers are in tempor ary operation (vehicles with rain-sensing
windshield wipers)
AUTO mode cannot be activa ted even if is pressed.
■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 oper-
ate properly when sunlight from the rising or
setting of the sun inte rmittently strikes the
windshield, or if bugs etc. are present on the
windshield.

WARNING
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be cau sed if the lever is pulled toward you and
held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

Do not add washer fluid when the engine is hot or running as washer fluid contains
alcohol and may catch fire if spilled on the engine etc.
NOTICE
■Do not use any fluid other than washer fluid
Do not use soapy water or engine antifreeze instead of washer fluid.
Doing so may cause streaking on the vehicle’s painted surfaces, as well as damaging

■Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the washer fluid bottle.
