Heating On cold days, use FLOOR and the outside air button 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 outlets. Your vehicle has heat ducts that are directed toward the rear seat. Keep the area under the front seats clear of obstructions so that 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. Defogging and Defrosting Windows Your system has two settings for clearing the front and side windows. For each setting, adjust the temperature control as desired. To defrost the front window quickly, turn the temperature control knob all the way in the red area. Use FRONT DEFROST and adjust the fan to the highest speed. To warm passengers while keeping the front window clean, use DEFOG. If you select RECIRCULATION while in VENT, BI-LEVEL or FLOOR modes, humid air can recirculate inside the vehicle and allow moisture to form on the windows. If this happens, either press the A/C button to on or select DEFROST or the DEFOG modes. Your vehicle is equipped with side window defogger vents. The side window defogger vents are located on the outside of the side instrument panel vents. To defrost the side windows, turn the temperature control knob all the way in the red area. Use FLOOR and adjust the fan to the highest speed. To control fogging of the windows, turn the temperature control knob all the way in the red area. Use DEFOG and adjust the fan to the highest speed. 3-4
