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. |
| • | This vehicle has a passenger compartment air filter. If the airflow
seems low when the fan is at the highest setting it may need to be replaced. For more
