following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs approximately
half of the air to the instrument panel outlets, and
then directs the remaining air to the oor outlets.
Cooler air is directed to the upper outlets and
warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
windshield and side windows.
The right knob can also be used to select defog or
defrost mode. Information on defogging and
defrosting can be found later in this section.
Recirculation mode is not allowed in this mode.
9(Fan):Turn the center knob clockwise
or counterclockwise to increase or decrease the
fan speed. In any setting other than off, the fan will
run continuously with the ignition on. The fan
must be turned on to run the air conditioning (AC)
compressor.

@(Recirculate):Press this button to prevent
outside air and odors from entering your vehicle or
to help heat or cool the air inside your vehicle
more quickly. An indicator light above the symbol
will come on in this mode. The air conditioning
compressor also comes on. This mode is not
available for oor, defog and defrost modes. When
the recirculation button is pressed, the recirculation
indicator light will ash ve times and outside
air will be delivered. Operation in this mode during
periods of high humidity and cool outside
temperatures may result in increased window
fogging. If window fogging is experienced, select
the defrost mode.
;(Outside Air):Press this button to allow
outside air to circulate through your vehicle.
An indicator light above the symbol will come on
in this mode.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. When
this button is pressed, an indicator light below the
symbol will come on to let you know the 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:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select air conditioning.
4. Select the coolest temperature.
5. Select the highest fan speed.
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 off the recirculation by pressing the outside
air button.
172

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.
The air conditioning compressor cannot be turned
on when the fan is off.
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 clear fog or frost from your
windshield and side windows. 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. For best results, clear all snow and ice
from the windshield before defrosting.
Turn the right knob to select the defog or
defrost mode.
-(Defog):This mode directs approximately half
of the air to the windshield and the side window
outlets and half to the oor outlets. When you
select this mode the system runs the air
conditioning compressor. To defog the windows
faster, turn the temperature control knob clockwise
to the warmest setting.
Recirculation mode is not available in defog mode.
0(Defrost):This mode directs most of the
air to the windshield, with some air directed to the
side window outlets and the oor outlets. When
you select this mode the system runs the air
conditioning compressor. To defrost the windows
faster, turn the temperature control knob
clockwise to the warmest setting.
Recirculation mode is not available in defog mode.
173

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
The rear window defogger will only work when the
ignition is in RUN.
<(Rear):Press the button to turn the rear
window defogger on or off. Be sure to clear
as much snow from the rear window as possible.
An indicator light below the symbol will come
on to let you know that the rear window defogger
is activated.
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. If turned on again, the defogger will
only run for approximately seven minutes before
turning off. If vehicle speed is greater than 50 mph
(80 km/h) and the rear defogger is active, it will
remain on as long as the speed is greater
than 50 mph (80 km/h). The defogger can also be
turned off by pressing the button again or by
turning off the engine.Notice:Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
Outlet Adjustment

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 deectors may
adversely affect the performance of the
system.

Passenger Compartment Air Filter
Passenger compartment air, both outside air
and recirculated air, is routed through a passenger
compartment lter. The lter removes certain
particles from the air, including pollen and dust
particles. Reductions in airow, which may
occur more quickly in dusty areas, indicate that
the lter needs to be replaced early.
The lter should be replaced as part of routine
scheduled maintenance. SeeScheduled
Maintenance on page 393for replacement
intervals. See your dealer for details on changing
the lter. To nd out what type of lter to use,
seeNormal Maintenance Replacement Parts on
page 405.To access the passenger compartment air lter
you must go through the glove box.
1. Open the glove box and remove all articles
from the inside.
2. Release the glove box stops by pushing them
both outward to let the glove box drop open
completely.
175

3. Pull each of the three tabs of the lter access
door down and open the access door
downward.4. Pull the lter out, keeping it face up so as not
to drop any dust into the passenger
compartment upon removal.
When installing a new air lter make sure the
AIR FLOW arrow is pointing downward. Reverse
Steps 1 through 4 making sure the glove box
door is back into place.

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
are 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 is a problem with your
vehicle.
When one of the warning lights comes on and
stays on as 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 are a big help.
177

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

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers
per hour (km/h).
Your vehicle’s odometer works together with the
driver information center. You can set a Trip A and
Trip B odometer. See “Trip Information” under
DIC Operation and Displays on page 195.
The odometer mileage can be checked without the
vehicle running. Simply open the driver’s door
and the mileage will be displayed briey.
If your vehicle ever needs a new odometer
installed, the new one will be set to the correct
mileage total of the old odometer.
Tachometer
The tachometer displays
the engine speed in
revolutions per
minute (rpm).
Notice:If you operate the engine with the
tachometer in the red warning area, your
vehicle could be damaged and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the red warning area.
