Use the thumbwheels located between the center outlets to open and close the
outlets. Move the lever in the center of each air outlet to adjust the direction of
the airflow.
Operation Tips
| • | Clear away any ice, snow or leaves from the air inlets at the base of
the windshield that may block the flow of air into the 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 of the vehicle more effectively. |
| • | If the vehicle has a passenger compartment air filter and the airflow
seems low when the fan is at the highest setting it may need to be replaced. For more
information, see
