Rain Sensitive Wipers
WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The multifunction switch must be positioned to 1 of the 5 sensitivity settings in order to turn the rain sensitive wiper system on. The sensitivity position closest to OFF is the least sensitive to moisture. The highest sensitivity position is the most sensitive to moisture. When the rain sensitive wiper system is active, the system will activate the wipers and adjust the wiper speed automatically when moisture is detected on the windshield. The rain sensor is used to detect the amount of moisture on the windshield. If moisture is present on the windshield, the rain sensor will send a signal to the wiper/washer module to activate the windshield wiper motor. The rain sensor is located on the windshield to the right of the rear view mirror.
