Your vehicle ventilation system supplies outside air into the vehicle when it is moving. Outside air will also enter the vehicle even when it is not moving by selecting any air mode and fan speed. The Saturn ventilation system will not supply outside air into the vehicle, however, if you have activated the "Recirculate" button.

Ventilation Tips

    • Keep the air path under the front seats clear of objects. This will help air to circulate throughout your vehicle.
    • Keep the hood and cowl air inlet free of ice, snow, or any other obstruction, such as leaves. The heater and defrosting system will work much better.
