Move the slider knobs (2) to change
the direction of the airflow.
Additional air vents are beneath the
windshield and the driver and
passenger side door windows. These
are fixed and cannot be adjusted.
Operation Tips
Clear away any ice, snow, or leaves
from air inlets at the base of the
windshield that could block the
flow of air into the vehicle.
Clear snow off the hood to
improve visibility and help
decrease moisture drawn into the
vehicle.
Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
Use of non-GM approved hood
deflectors can adversely affect the
performance of the system. Check
with your dealer before adding
equipment to the outside of the
vehicle.
Do not attach any devices to the
air vent slats. This restricts airflow
and may cause damage to the air
vents.

Passenger Compartment
Air Filter
The filter reduces dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle. The
filter should be replaced as part of
routine scheduled maintenance. See
Maintenance Schedule 0 291.
See your dealer regarding replacement
of the filter.
Service
All vehicles have a label underhood
that identifies the refrigerant used in
the vehicle. The refrigerant system
should only be serviced by trained and
certified technicians. The air
conditioning evaporator should never
be repaired or replaced by one from a
salvage vehicle. It should only be
replaced by a new evaporator to
ensure proper and safe operation.
