ers will operate once to show that AUTO mode is activated.
If the temperature of the raindrop sensor is 85°C (185°F) or higher, or -

operate properly when sunlight from
the rising or setting of the sun intermit-
tently strikes the windshield, or if bugs
etc. are present on the windshield.
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 or anything else do not become caught in the windshield wip-
ers.
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.
