Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed.
1. Press the AUTO button.
2. Adjust the temperature to 75É F (24É C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not go
into automatic mode.
In cold weather, the system will start at reduced fan
speeds to avoid blowing cold air into your vehicle
until warmer air is available. The system will
start out blowing air at the ¯oor but may change
modes automatically as the vehicle warms up
to maintain the chosen temperature setting. The
length of time needed for warm up will depend on
the outside temperature and the length of time
that has elapsed since your vehicle was last driven.
3. Wait for the system to regulate. This may take from
10 to 30 minutes. Then adjust the temperature, if
necessary.
Do not cover the solar sensor located in the center of
the instrument panel, near the windshield. For more
information on the solar sensor, see ªSensorsº later in
this section.
Manual Operation
Pressing the FAN or AIR FLOW buttons cancels
automatic operation and places the system in manual
mode. Press the AUTO button to return to automatic
operation.
TEMP (Temperature):To manually adjust the
temperature inside the vehicle, push the TEMP arrow.
Push the TEMP up arrow for warmer temperature
settings and the TEMP down arrow for cooler
temperature settings. The setting will be shown on the
display. The display will return to the outside
temperature after a few seconds.
9FAN:Pressing the FAN button will display and hold
the current fan speed while in manual mode. If you
want the fan to run at a lower speed, push the down
arrow on the FAN button. If you want to increase the fan
speed, push the up arrow on the FAN button. The fan
indicators will also be shown on the display.
If the air¯ow seems low when the fan is at the highest
setting, the passenger compartment air ®lter may
need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-27.
AIR FLOW:Pressing the AIR FLOW button will display
and hold the current setting while in manual mode.
Use the up and down arrows on the AIR FLOW button
to cycle through the available modes.
3-23

Use the thumbwheel
located between the rear
passenger outlets to
open and close the outlets.
Adjust the direction of
the air¯ow from side
to side with the levers in
the center of each
rear outlet.
Operation Tips
·
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the ¯ow of air into your vehicle.
·Use of non-GM approved hood de¯ectors 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 air¯ow seems low when the fan is at the
highest setting, the passenger compartment air ®lter
may need to be replaced. See
Passenger
Compartment Air Filter on page 3-27.
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment ®lter, which is part of a three piece ®lter
system. The ®lter removes certain particles from the air,
including pollen and dust particles. Reductions in
air¯ow, which may occur more quickly in dusty areas,
indicate that the ®lter needs to be replaced early.
The particle ®lter is located inside of the air control
module. The air control module is located behind
an access panel near the accelerator pedal.

Engine Air Cleaner/Filter
SeeEngine Compartment Overview on page 5-12for
the location of the engine air cleaner/®lter.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/®lter every 15,000 miles (25
000 km) and replace every 30,000 miles (50 000 km). If
you are driving in dusty/dirty conditions, inspect the
®lter at each engine oil change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/®lter remove the ®lter from the
vehicle and lightly shake the ®lter to release loose
dust and dirt. If the ®lter remains ªcakedº with dirt, a new
®lter is required.
To inspect or replace the engine air cleaner/®lter, do the
following:
1. Remove the wing nuts on the engine air
cleaner/®lter housing cover.
