Air Vents
Use the slider switch in the center of the outlet, to change the direction of the airflow. Use the thumbwheel near the outlet to control the amount of airflow or to shut off the airflow.
Keep all outlets open whenever possible for best system performance.
Operation Tips
• Clear away any ice, snow, or leaves from the air inlets at the base of the windshield that can 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 all seats clear of objects to help circulate the air inside the vehicle more effectively.
• If fogging reoccurs while in vent or bi-level modes with mild temperature throughout the vehicle, turn on the air conditioner to reduce windshield fogging.
