Outlet Adjustment
Use the levers, located in the middle of the front
outlets, to change the direction of the airflow.
Use the thumbwheel located between the outlets
to turn them on and off.
If your vehicle has rear seat outlets, adjust the
direction of the airflow using the lever in the center
of each outlet.
Operation Tips
•
Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that
could block the flow of air into your vehicle.
•
Use of non-GM approved hood deflectors can
adversely affect the performance of the system.
•
Keep the path under the front seats clear of
objects to help circulate the air inside the
vehicle better.
Passenger Compartment Air Filter
The passenger compartment air filter traps most of
the pollen from the air entering your vehicle. Like
your vehicle’s engine air cleaner/filter, it may need
to be changed periodically. For how often to change
the passenger compartment air filter, see
Scheduled Maintenance on page 442 .
The access panel for the passenger compartment
air filter is located under the hood near the
windshield, on the passenger’s side of the vehicle.
