On cool, but sunny days, the sun may warm your upper body, but your lower body may not be warm enough. You can use bi-level with the temperature knob in the middle and the A/C button pressed in. The system directs slightly warmer air to your lower body. Heating On cold days, use floor mode 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 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 defrost the front window quickly, turn the temperature knob all the way in the red area. Use front defroster and adjust the fan to the highest speed. To warm passengers while keeping the front window clean, use defog. When you switch to defog or defrost modes your system will automatically move from recirculation into outside air. When you move the mode knob back to vent or bi-level, the system will move back into recirculation. When the car is turned off and back on the system will default to outside air automatically. The recirculation setting in cold weather should be used only for outside odor control so that fog formation on the windows is reduced. Your vehicle is equipped with side window defogger vents. The side window defogger vents are located above the side instrument panel vents. To defrost the side windows, turn the temperature knob all the way in the red area. Use floor mode and adjust the fan to the highest speed. To defog the side windows while using air conditioning, use bi-level and adjust the fan to the highest speed and press the A/C button so that the indicator light is glowing. For added airflow to the side windows, aim the side vents toward the windows and close the center vents. Defogging and Defrosting Windows Your system has two settings for clearing the front and side windows. For each setting, adjust the temperature knob as desired. 3-4
