Use the air outlets located in the center and on the side of the instrument panel to direct the airflow.

The vehicle has air outlets that allow you to adjust the direction and amount of airflow inside the vehicle. Move the louvers up or down or turn them clockwise or counterclockwise to change the direction of the airflow.

The vehicle has flow through ventilation that allows outside air to be forced through the ventilation system when the vehicle is moving. Outside air will enter the vehicle when the air conditioning fan is running. Flow through ventilation can be stopped in vent and bi-level modes by pressing the recirculation button.

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.
