AC (Air Conditioning):Press this button to turn the
air-conditioning system on or off. When A/C is pressed,
an indicator light above the button will come on to let
you know that air conditioning is activated.
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select A/C.
4. Select the recirculation mode.
5. Select the coolest temperature.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
The air-conditioning system removes moisture from
the air, so you may sometimes notice a small amount of
water dripping underneath your vehicle while idling or
after turning off the engine. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass. This
can be minimized if the climate control system is
used properly. There are two modes to choose from to
clear fog or frost from your windshield. Use the
defog mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more quickly.
Turn the right knob to select the defog or defrost mode.
-(Defog):This mode directs half of the air to the
windshield and half to the oor outlets with a small
amount directed to the side windows. When you select
this mode, the system turns off recirculation
automatically and runs the air-conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in
the defog mode. Do not drive the vehicle until all the
windows are clear.
1(Defrost):This mode directs most of the air to the
windshield with some air directed to the oor vents.
In this mode, the system will automatically force outside
air into your vehicle and run the air-conditioning
compressor. Recirculation cannot be selected while in
the defrost mode.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
defogger on or off. An indicator light above the
button will come on to let your know that the rear
window defogger is activated. Be sure to clear as much
snow from the rear window as possible.
The rear window defogger will turn off approximately
15 minutes after the button is pressed. If turned on
again, the defogger will only run for approximately seven
minutes before turning off. The defogger can also be
turned off by pressing the button again or by turning off
the engine.
If your vehicle has heated outside mirrors, the mirrors
will also heat when the rear defogger is on. SeeOutside
Heated Mirrors on page 2-39for more information.
Notice:Don’t use anything sharp on the inside of
the rear window. If you do, you could cut or damage
the warming grid, and the repairs wouldn’t be
covered by your warranty. Do not attach a temporary
vehicle license, tape, a decal or anything similar
to the defogger grid.
Automatic Climate Control System
If your vehicle has this system, you can control the
heating, cooling and ventilation in your vehicle
automatically.

Automatic Operation
To switch the temperature display from degrees
Fahrenheit to degrees Celsius, press and hold the
AUTO, ECON, and MODE buttons at the same time.
AUTO (Automatic):When automatic operation is active
the system will control the inside temperature, the air
delivery, and the fan speed.
OFF:Press this button to turn off the entire climate
control system. Outside air will still enter the vehicle.
Use the steps below to place the entire system in
automatic mode:
1. Put the fan knob on AUTO and press the AUTO
button.
When AUTO is selected, the display will change to
show the current set temperature, delivery mode
and fan speed.
When auto is selected, the air conditioning operation
and air inlet will be automatically controlled. The
air conditioning compressor will run when as
necessary. The air inlet will normally be set to
outside air. If it’s hot outside, the air inlet may
automatically switch to recirculate inside air to help
quickly cool down your vehicle. The light on the
button will illuminate in recirculation.2. Set the temperature.
To nd your comfort setting, start with a 71°F (22°C)
temperature setting and allow about two to three
minutes for the system to regulate. Turn the
temperature knob to adjust the temperature setting
as necessary. If you choose the temperature setting
of 60°F (15°C) the system will remain at the
maximum cooling setting. If you choose the
temperature setting of 90°F (32°C) the system will
remain at the maximum heat setting. Choosing either
maximum setting will not cause the vehicle to heat or
cool any faster.
Be careful not to cover the sensor located on the
top of the instrument panel near the windshield. This
sensor regulates air temperature based on sun
load, and also turns on your headlamps. See
“Sensor” later in this section for more information.
To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm air is
available. The length of delay depends on the
engine coolant temperature. Pressing the fan switch
will override this delay and change the fan to a
selected speed.

maximum air conditioning performance in hot weather.
Press this button again to allow outside air to enter the
vehicle. The light on the recirculation button will go off.
If you select recirculation while in defrost or defog, the
system will not switch to that mode. This is to prevent
fogging.
When the weather is cool or damp, operating the system
in recirculation for extended periods of time may cause
fogging of the vehicle’s windows. To clear the fog, select
either defog or front defrost. The air conditioning
compressor will run automatically to help dehumidify
the air.
ECON:Pressing this button will disable the air
conditioning compressor. A/C OFF will be displayed on
the screen. Press the button again to allow for
automatic operation of the air conditioning compressor.

Operation Tips

Clear away any ice, snow or leaves from the air
inlets at the base of the vehicle that may block
the ow of air into your vehicle.
Use of non-GM approved hood deectors 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
Your vehicle may be equipped with a passenger
compartment air lter. It is located underneath the hood
just below the windshield wiper arm on the passenger’s
side of the vehicle.
The lter traps most of the pollen from air entering the
Climate Control System. Like your engine’s air
cleaner/lter, it may need to be changed periodically to
insure system performance. For information on how
often to change the passenger compartment air
lter, seeScheduled Maintenance on page 6-4.For the type of lter to use, seeNormal Maintenance
Replacement Parts on page 6-13.
To change the passenger compartment air lter, use the
following steps:
1. Open the hood. Locate the passenger compartment
air ler access panel.
2. Peel back the hood weatherstrip from the
passenger’s side of the vehicle halfway to center.
3. Use a tool to open the passenger compartment air
lter access door.
4. Remove any leaves or other debris from the
lter area.

5. Release the two locking tabs and pull the lter out.
6. Reverse the steps to install the new air lter.
Warning Lights, Gages,
and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they’re working. If you are
familiar with this section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly — and even
dangerous. So please get to know your warning lights
and gages. They’re a big help.
