Rear Window Defrost
NOTE:
When you switch maximum defrost on, the heated windshield, rear window defrost and air conditioning turn on. When you switch maximum defrost off, the heated windshield and rear window defrost remain on.
When the rear window defrost is activated from the switch (integral to the HVAC module), the rear window defrost grids are energized, warming/heating the glass to improve rearward visibility.
