CAUTION
 Caution regarding the use of windshield wipers in "AUTO" mode (vehi-
cles with rain-sensing windshield wipers)
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 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 fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low 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 over-
heat.
 When a nozzle becomes blocked
In this case, contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
 To prevent 12-volt battery discharge
Do not leave the wipers on longer than necessary when the hybrid system is
off.
