Ventilation System
Use when outside temperatures are mild, and little
heating or cooling is needed. Turn the right knob to
VENT. Airflow is directed through the instrument panel
outlets. 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 the vehicle when the heater or the air
conditioning fan is running.
Adjust the direction of
airflow by moving the
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, reducing the
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 and moisture, and reduces the
chance of fogging the inside of your windows.
Keep the a i r path under the front seats clear of objects.
This helps
air
to circulate throughout your vehicle.
