Outlet Adjustment
Use the knob located in the center of the outlet, to
change the direction of the air flow.
Operation Tips
• Clear away any ice, snow or leaves from the air
inlets on the hood 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 your vehicle more
effectively.
