Use the air outlets located in the center and outboard sides of the instrument
panel, to change the direction of the air flowing through the vents.
Operation Tips
| • | Clear away any ice, snow or leaves from the outside air inlets at the
base of the windshield. |
| • | Use of non-GM approved hood deflectors can adversely affect the performance
of the system. |
| • | Keep the area under the front seats clear of objects for more effective
air circulation. |
| • | If the airflow seems low when the fan is at the highest setting, the passenger
compartment air filter might need to be replaced. For more information, see Passenger
Compartment Air Filter later in this section. |
