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:
If the battery voltage is low, the windshield deicer system may not operate. When "Operation of Electrical Items Restricted." is not displayed on the multi-information display in the combination meter assembly, check the Data List item "Battery Control Count (Body ECU)".
