STOP” switch is in IGNITION ON mode, the wipers will operate once to show
that AUTO mode is activated.●
When the sensor sensitivity ring is turn ed toward high while in AUTO mode, the
wipers will operate once to indicate that the sensor sensitivity is enhanced.●
If the temperature of the raindrop sensor is 194  F (90  C) or higher, or 5  F
