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 knob all the way in the red area. Use defrost 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 into vent or bi-level modes, the system will move back into recirculation. When the vehicle is turned off and back on, the system will default to outside air automatically. 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, select either the defog or defrost mode. Recirculation mode 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 outlets are located on the outside of 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 mode and adjust the fan to the highest speed and press the A/C button. For additional airflow to the side windows, aim the side outlets toward the windows and close the center outlets. Recirculation will not operate in defog or defrost. This is done to prevent recirculation of humid inside air and allow the system to work properly. The system will automatically default to outside air when defog or defrost modes are selected. 3-5
