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 is at the
highest setting, the passenger compartment
air filters, if equipped, may need to be replaced. For
more information, see “Passenger Compartment
Air Filter” following and
Short Trip/City Scheduled
Maintenance on page 6-7

Passenger Compartment Air Filter
All models come equipped from the factory with a slot in
the ventilation system that is ready to accept passenger
compartment air filters. These filters are available for
purchase from your dealer. You will need to install
two filters to provide the proper filtration.
Both outside and recirculated air flows through these
filters and removes certain contaminates including pollen
and dust particles.
Reductions in airflow which occur more quickly in dusty
areas, may indicate that the filters need to be replaced
earlier than listed in the maintenance schedule. For how
often to replace your air filters, see
Maintenance
Requirements on page 6-2
.
The access panel for the air filters is behind the
glove box.
