Air Vents
Adjustable air vents are in the center and on
the side of the instrument panel. Use the
sliding knobs on the air vents to change the
direction of the airflow. Slide the knob up or
down to open or close off the airflow.
Air vents blow warm air on the side
windows in cold weather. If Floor, Defog,
or Defrost modes are selected, a small
amount of air will come from the vents
close to the window. If the airflow is shut
off using the sliding knobs, warm air will be
directed to the other instrument panel
vents. This is normal operation.
Use the sliding knobs to turn vent airflow
on or off based on the mode selected.
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.
Maintenance
Passenger Compartment Air Filter
The passenger compartment air filter
reduces dust, pollen, and other airborne
irritants from outside air that is pulled into
the vehicle. The filter will need to be
replaced periodically. SeeMaintenance
Schedule 0312.
Using the climate control system without an
air filter installed is not recommended.
Water or other debris could enter the
system and result in leaks or noises. Always
install a new filter when removing the old
filter.
For more information on filter replacement,
see your dealer.
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.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere is
harmful to the environment and may also
create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires periodic
maintenance. See Maintenance Schedule
0 312.

Automatic Transmission Fluid
How to Check Automatic Transmission
Fluid
It is not necessary to check the transmission
fluid level. A transmission fluid leak is the
only reason for fluid loss. If a leak occurs,
take the vehicle to your dealer and have it
repaired as soon as possible.
There is a special procedure for checking and
changing the transmission fluid. Because this
procedure is difficult, this should be done at
your dealer. Contact your dealer for
additional information.
Caution
Use of the incorrect automatic
transmission fluid may damage the
vehicle, and the damage may not be
covered by the vehicle warranty. Always
use the correct automatic transmission
fluid. SeeRecommended Fluids and
Lubricants 0321.
Change the fluid and filter at the intervals
listed in Maintenance Schedule 0312, and be
sure to use the fluid listed in Recommended
Fluids and Lubricants 0321.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the engine
compartment on the passenger side of the
vehicle. See Engine Compartment Overview
0 240.
When to Inspect/Replace the Engine Air
Cleaner/Filter
For intervals on changing and inspecting the
engine air cleaner/filter, see Maintenance
Schedule 0312.
How to Inspect/Replace the Engine Air
Cleaner/Filter
Do not start the engine or have the engine
running with the engine air cleaner/filter
housing open. Before removing the engine
air cleaner/filter, make sure that the engine
air cleaner/filter housing and nearby

tap and shake the engine air cleaner/filter
(away from the vehicle), to release loose
dust and dirt. Inspect the engine air cleaner/
filter for damage, and replace if damaged.
Do not clean the engine air cleaner/filter or
components with water or compressed air.
To inspect or replace the air cleaner/filter:
