Comfort Controli &Audio Systems I ll To Defog the Side Windows: Your vehicle has side window defoggers built into the front door panels. Some air is directed through these vents when the climate control system is placed in DEFOG or HEAT. For maximum air flow to the side windows, turn the right knob to BILEV, turn the fan control to HIGH, close the center vents and direct the side vents toward the side windows. This setting does not direct any air to the windshield. Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. Press the defogger switch. The indicatorlight will glow. If your vehicle is traveling under 45 mph (70 l d h ) , the rear window defogger will turn off automatically after about 10 minutes of use (and after about 5 minutes on each subsequent use). If your vehicle is traveling over 45 mph (70 ltm/h), the defogger will operate continuously. You can turn the defogger off by turning off the ignition or pressing the switch again. 110
