Type B
The defroster heats the window to remove frost, fog and thin ice from the interior and exterior of the rear window, while the engine is running.
To activate the rear window defroster, press the rear window defroster button located in the center facia switch panel. The indicator on the rear window defroster button illuminates when the defroster is ON.
If there is heavy accumulation of snow on the rear window, brush it off before operating the rear defroster.
The rear window defroster automatically turns off after approximately 20 minutes or when the ignition switch is turned off. To turn off the defroster manually, press the rear window defroster button again.
Front wiper deicer (if equipped)
If your vehicle is equipped with the front wiper deicer, it will be operating at the same time you operate the rear window defroster.
