Turn the air outlets, located in the middle and at each outboard side of the instrument panel, to adjust the direction of the airflow.

Operation Tips

    • Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that may block the flow of air into the vehicle.
    • Use of non-GM approved hood deflectors may adversely affect the performance of the system.
    • Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively.
    • If the airflow seems low when the fan is at the highest setting, the passenger compartment air filter may need to be replaced. See "Passenger Compartment Air Filter" following, for more information.
