Rear Window Defogger

To defog or de-ice the rear window, press the button.
The ignition switch must be in the On position.
The heat generated by the fine wires of the heating element bonded to the inner surface of the glass quickly clears the window.
When the rear window defogger is on, the indicator lamp on the instrument panel illuminates.
To turn off the rear window defogger, press the button again. Turn off the defogger immediately after the glass has cleared.
Running the defogger for a long period drains the battery, especially during short trips. The defogger is not intended for drying the glass in rain or melting snow.
* Operate the defogger only with the engine running.
* When cleaning the rear window, do not damage the heating element.
