The Saturn Aura is available in both gas-electric hybrid and traditional gasoline only models. Both models have a compartment behind the glove box that accommodates a cabin air filter. The cabin air filter prevents dust and allergens from entering the air-conditioning system through the outside vents. Once the filter has been installed, it should be replaced when it becomes dirty, or after every 10,000 miles driven.
Open the glove box. Unhook the stopper arm from its hook on the right side of the open glove box.
Press in on the sides of the glove box to unhook it from the dash. Pivot the glove box down toward the floor.
Cut the plastic rectangle that is labeled "cut out for air filter" with the razor blade. Discard the cut out portion.
Slide the cabin air filter into the slot. Make sure the "airflow" arrow printed on the filter is pointing toward the floor of the Saturn Aura.
Raise the glove box to hook it back into the dash. Replace the stopper arm on the right side.
