Outlet Adjustment
Use the thumbwheels located next to and below
the air outlets to change the direction of the airflow
and to open and 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 path under the front seats clear of
objects to help circulate the air inside of
your vehicle more effectively.
Passenger Compartment Air Filter
Passenger compartment air, both outside air
and recirculated air, is routed through a passenger
compartment filter. The filter removes certain
particles from the air, including pollen and dust
particles. Reductions in airflow, which may
occur more quickly in dusty areas, indicate that
the filter needs to be replaced early.
The filter should be replaced as part of routine
scheduled maintenance. See Scheduled
Maintenance on page 375 for replacement
intervals. See your dealer for details on changing
the filter. To find out what type of filter to use,
see Normal Maintenance Replacement Parts on
page 387.
To access the passenger compartment air filter
you must go through the glove box.
1. Open the glove box and remove all articles
from the inside.
2. Tilt the glove box door down by squeezing on
each side of the glove box until the door can
be lowered from its track. Lower the glove
box door.
