windshield, or if bugs etc. are present on the
windshield.

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)

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 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.
