“POWER” switch is in ON mode, the wipers will operate once to show
that AUTO mode is activated.
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,

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 etc. do not become caught in the windshield wipers.

of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from
the rising or setting of the sun intermit-
