Air Vents
Use the air outlets, located in the center and on the side of the instrument panel, to direct the airflow. Use the thumbwheels located near the center air outlets, to open or close off the airflow.
Operation Tips
○ Clear away any ice, snow, or leaves from air inlets at the base of the windshield
that could block the flow of air into the vehicle.
○ Keep the path under the front seats clear of objects to help circulate the air
inside of the vehicle more effectively.
○ Use of non&-GM approved hood deflectors can adversely affect the performance of
the system. Check with your dealer before adding equipment to the outside of the
vehicle.
