Heating Press the MODE button to select heater. Adjust the interior temperature to a comfortable level and if the fan speed needs adjusting, press the up or down arrow. Outside air will be brought in and sent through the floor, air conditioning or bi-level outlets (depending on the condition). The heater works best if you keep your windows closed while using it. Rear Window Defogger The lines you see on the rear window warm the glass. Press this button to turn on the rear defogger. With it, the rear window and both outside rearview mirrors are heated. The system will automatically shut off after 10 minutes. If further defogging is desired, press the button again. Do not attach a temporary vehicle license, tape or decals across the defogger grid on the rear window. Defrosting Use defrost to remove fog or ice from the windshield quickly in extremely humid or cold conditions. Press the MODE button. If you select DEFROST, adjust the fan speed by pressing the fan button up or down. If you select DEFROST from AUTO, the system will control the fan speed. The temperature also needs to be adjusted by turning the TEMP/AUTO knob. Recirculation is not available in the defrost or defog modes. 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 or the integrated rear window antenna, and the repairs wouldn't be covered by your warranty. 3-7
