Defogging and Defrosting Your system has two settings for clearing the front and side windows. To defrost the windows quickly, use DEFROST with the temperature knob all the way in the red area. To warm passengers while keeping the windows clean, use DEFOG. To defog the side windows, set the right control to BI-LEVEL and the fan control to the highest setting. To defog the side windows while using the air conditioner, set the right control to BI-LEVEL, the fan control to the highest setting, and press the A/C button. For both systems, aim the side vents toward the side windows. For increased airflow to the side vents, close the center vents. Rear Window Defogger (If Equipped) The rear window defogger uses a warming grid to remove fog from the rear window. Press the button to turn the defogger on. It will turn itself off after about 10 minutes. If you turn it on again, the defogger will only run for about five minutes before turning off. You can also turn it off by pressing the button again. Do not attach a temporary vehicle license across the defogger grid on the rear window. 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. 3-6
