SYSTEM DESCRIPTION
GENERAL
The windshield deicer system uses thin heater wires attached to the inside of the windshield glass to help deice the window surface more quickly. An indicator light illuminates while the system is operating. This system automatically turns off after approximately 15 minutes.
NOTICE:
