Use the thumbwheels near each vent to open and close off the airflow. Operation Tips . Keep all outlets open whenever possible for best system performance. Keep the path under all seats clear of objects to help circulate the air inside the vehicle more effectively. Use of non-GM approved hood deflectors can adversely affect the performance of the system. Do not attach any devices to the air vent slats, this restricts airflow and may cause damage to the air vents. . . .
