The flow through outlets on your vehicle allow outside air to enter your vehicle while it is moving. Outside air will also enter your vehicle while the air-conditioning compressor is running.

Use the thumbwheels located in the center and on the sides, to change the direction of the air flowing through the outlets.

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 your 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 your vehicle more effectively.
