Defogging and Defrosting On cool, humid days, use defog to keep the windshield and side windows clear. Use defrost to remove fog or ice from the windshield in extremely humid or cold conditions. Use defrost with the temperature knob toward the red area and the fan control turned all the way to the right. The rear window defogger will only work if the ignition is in RUN. For best results, clear the window of as much snow or ice as possible first. The defogger will shut itself off after several minutes. If you need additional warming time, press the button again. You can turn the defogger off at any time by pressing the button. If your vehicle is equipped with heated outside mirrors, the rear window defogger button will also activate the heated outside mirrors. Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window. Rear Window Defogger Do not remove the rear window with the rear defogger on. You may see a discharge spark coming from the latch area if you remove the window with the defroster on. The lines running across the rear window are the rear window defogger lines. The lines warm the glass. To turn on the rear window defogger, press this button located below the mode knob. NOTICE: Don't use a razor blade or something else sharp on the inside of the rear window. If you do, you could cut or damage the warming grid, and the repairs wouldn't be covered by your warranty. 3-8
