outside air mode on. When this mode is on, outside air
will circulate throughout your vehicle. When the
button is pressed, an indicator light in the button will
come on to let you know that it is activated. The outside
air mode can be used with all modes, but it cannot
be used with the recirculation mode.

the indicator lamp.
The outside air mode can be used with all modes, but it
cannot be used with the recirculation mode.
If you are in city traffic, your vehicle is stopped and
idling, or the weather is hot, the system may switch from
the outside air mode to the recirculation mode. To
prevent the air inside of your vehicle from becoming too
stale, be sure to return to the outside air mode
periodically.?(Recirculation):This mode keeps outside air
from coming in the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or help
heat or cool the air inside your vehicle more quickly.
Press this button to turn the recirculation mode on.
When the button is pressed, an indicator light will come
on. The air-conditioning compressor also comes on.
You may have to set the instrument panel brightness
control to the highest setting during the day to see
the indicator lamp.
The recirculation mode cannot be used with outside air
modes.

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 recirculation mode.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
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
inside of 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 the 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 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 clockwise to select the defog or
defrost mode.
-(Defog):This mode directs air equally to the
windshield and the ¯oor outlets. When you select this
mode, the system turns off recirculation and runs
the air-conditioning compressor unless the outside
temperature is below 40ÉF (4ÉC). The recirculation mode
cannot be selected while in the defog mode.
Do not drive the vehicle until all the windows are clear.
0(Defrost):This mode directs half of the air to
the windshield and side window vents and half to the
¯oor vents. In this mode, the system will automatically
force outside air into your vehicle. The recirculation
mode cannot be selected while in the defog mode. The
air conditioning compressor will run automatically in
this setting, unless the outside temperature is below
40ÉF (4ÉC).
Do not drive the vehicle until all the windows are clear.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
approximately 20 minutes after the button is pressed. If
turned on again, the defogger will run for the same
amount of time. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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.
Outlet Adjustment
Use the knob located
below or to the side of the
outlet, to change the
direction of the air ¯ow.

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 your vehicle more
effectively.
·If the air¯ow seems low when the fan is at the
highest setting, the passenger compartment
air ®lter, if equipped, may need to replaced. For
more information, see
Passenger Compartment Air
Filter on page 3-26andPart A: Scheduled
Maintenance Services on page 6-4.
Passenger Compartment Air Filter
Your vehicle may be equipped with a passenger
compartment particulate air ®lter. It is located
underneath the hood just below the windshield wiper
arm on the passenger's side of the vehicle, underneath
the air inlet grille.
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, see
Scheduled Maintenance on page 6-5.
3-26

To change the passenger compartment air ®lter, use the
following steps:
1. Turn off the ignition when the windshield wipers are
in the up position.
2. Raise the vehicle hood.
3. Disconnect the windshield washer pump hose from
the fender rail and air inlet grille.
4. Peel back the hood weatherstrip from the
passenger's side of the vehicle halfway to center.5. Remove the air inlet grille retainers.
6. Remove the air inlet grille.
7. Remove the air de¯ector grille in the compartment.
8. Remove the old passenger compartment air
®lter.
9. Reverse the steps to install the new air ®lter.
For the type of ®lter to use, see
Normal Maintenance
Replacement Parts on page 5-105.

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 brie¯y 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.
Your vehicle may also have a Driver Information Center
(DIC) that works along with the warning lights and
gages. See
Driver Information Center (DIC) on
page 3-49.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You'll know how
fast you're going, about how much fuel is in your tank and many other things you need to drive safely and
economically.
