Heating On cold days, use FLOOR with the temperature knob all the way in the red area. The system will bring in outside air, heat it and send it to the floor ducts. Your vehicle has heat ducts that are directed toward the rear seat. Keep the area under the front seats clear of obstructions so the heated air can reach the rear seat passengers. If your vehicle has an engine coolant heater, you can use it to help your system provide warm air faster when it's cold outside (0_F (-18_C) or lower). An engine coolant heater warms the coolant your engine and heating system use to provide heat. See "Engine Coolant Heater" in the Index. 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. 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. 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. 3-5
