Outlet Adjustment

Use the levers, located in the middle of the front outlets, to change the direction of the airflow. Use the thumbwheel located between the outlets to turn them on and off.

If the vehicle has rear seat outlets, adjust the direction of the airflow using the lever in the center of each outlet.

Operation Tips

• Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that could block the flow of air into the vehicle.

• Use of non-GM approved hood deflectors can adversely affect the performance of the system.

• Keep the path under the front seats clear of objects to help circulate the air inside the vehicle better.
