RX350/270_EE
■The windshield wipers and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
■Effects of vehicle speed on wiper operation
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)
When low speed wiper operation is selected, wiper operation will be switched from
low speed to intermittent wiper operation only when the vehicle is stationary.
(However, when the sensor sensitivity is adjusted to the highest level, the mode can-
not be switched.)
Washer/wiper dual operation
The wipers will automatically
operate a couple of times after
the washer squirts. (After oper-
ating several times, the wipers
operate one more time after a
short delay to prevent dripping.)
If the headlights are on, the
headlight cleaners will operate
once.

■Raindrop sensor
●If the wiper switch is turned to the position while the “ENGINE START
STOP” switch is in IGNITION ON mode, the wipers 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 90°C (194°F) or higher, or -15°C
(5°F) or lower, automatic operation may not occur. In this case, operate the wip-
ers 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 wind-
shield washer fluid reservoir.
CAUTION
■Caution regarding the use of windshield wipers in AUTO mode
The windshield wipers may operate unexpectedly if the sensor is touched or the
windshield is subject to vibration in AUTO mode. Take care that your fingers etc. do
not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes warm. The
fluid may freeze on the windshield and cause low visibility. This may lead to an acci-
dent, resulting in death or serious injury.
●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.
