yellowblue If you select RECIRCULATION while in the 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 outlets. The side window defogger outlets are located on the outside of the side instrument panel outlets. 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 to the red area. Use DEFOG 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. For added airflow to the side windows aim the side vents toward the windows and close the center outlets. RECIRCULATION will not work in DEFROST and DEFOG. This is done to prevent recirculation of humid inside air and allow the system to work properly. Rear Window Defogger (If Equipped) The rear window defogger uses a warming grid to remove fog from the rear window. Press the defogger switch. The indicator light will glow. The rear window defogger will turn itself off after about 10 minutes after the first time the button is pressed, and after 5 minutes each additional time the button is pressed. You can turn the defogger off by pressing the button again or turning off the ignition. Do not attach a temporary vehicle license across the defogger grid on the rear window. 3-5
