Use the lever located in the center of each outlet to change the direction of
the airflow, either side-to-side or up and down. Use the thumbwheels to open or close
the outlets to adjust the airflow.
Turn the thumbwheel towards the vehicle door to open the outlets and allow the
maximum amount of air to enter your vehicle. Turn the thumbwheel towards the center
console to close the outlets and minimize the amount of air entering the
vehicle.
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 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 of your vehicle more effectively. |
| • | If the airflow seems low when the fan speed is at the highest setting,
the passenger compartment air filter may need to be replaced. For more information,
