Set the center knob to the temperature desired. Your Pontiac's flow-through ventilation system supplies outside air into the vehicle when it is moving. Outside air will also enter thevehicle when the heater or the air conditioning fan isrunning. Adjust the direction of airflow by movingthe louvered vents. Ventilation Tips 0 Keep the hood and front air inlet free of ice, snow or any other obstruction (such as leaves). The heater and defroster will work far better, reducingthe chance of fogging the inside of your windows. When you enter a vehicle in cold weather, turn the fan control knob to the highest position for a few moments before driving off. This helps clear the intake ducts of snow andmoisture, and reducesthe chance of fogging the inside of your windows.
