■Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-
ers)
With the settings other than “AUTO” also, the time until drip prevention wiper sweep
occurs is changed depending on vehicle speed.
With the low speed wiper operation 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 cannot be switched.)
■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.
WARNING
■Caution regarding the use of windshield wipe rs in “AUTO” mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in “AUTO” mo de. Take care that your fingers etc. anything
else does 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 the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may overheat.
■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.
