Outlet Adjustment
Use the thumbwheel to open or close the outlets.
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 area around the base of the
instrument panel console and air path under
the seats clear of objects to help circulate
the air inside of your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air filter removes
certain particles from the air, including pollen and
dust particles. Reductions in airflow, which
may occur more often in dusty areas, indicate that
the filter may need to be replaced early.
The filter should be replaced as part of the routine
scheduled maintenance. See Scheduled
Maintenance on page 465 for more information.
To check or replace the air filter, do the following:
1. With the hood open, unlatch and remove
the access panel.
The passenger compartment air filter and
access panel are located on the passenger’s
side of the engine compartment near the
battery. See Engine Compartment Overview
on page 374 for more information on location.
2. Pull the old filter out of the housing.
3. Insert the new filter into the housing.
4. Reinstall the air filter access panel.
