To change the current mode, select one of the following:
H(Vent):This mode directs most of the air to the
instrument panel outlets, with a very small amount of air
directed to the ¯oor outlets.
%(Bi-Level):This mode directs approximately half of
the air to the instrument panel outlets, and then
directs most of the remaining air to the ¯oor outlets.
Some air may be directed toward the windshield. 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 outboard
outlets (for the side windows) and some air directed to
the windshield.
The MODE button can also be used to select the defog
mode. Information on defogging and defrosting can
be found later in this section.
9(Fan):Press the button with the fan symbol to
manually increase or decrease the fan speed. Keep
pressing the up or down arrow on this switch until the
desired fan speed appears on the display.Pressing the arrows will delete AUTO from the digital
display. The fan graphics with the fan speed bars will be
shown. To increase the fan speed so that more air
¯ows into the vehicle, press the up arrow on the
fan switch. To decrease the fan speed and air¯ow,
press the down arrow. The AUTO button must be
pressed to return to the automatic fan control.
:(Outside Air):Press this button to turn the
outside air mode on or off. 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
cannot be used with the recirculation mode.
When in the AUTO mode, the system automatically
selects outside air instead of recirculation, as required,
to control the temperature in the vehicle. By pressing
outside air, the system will lock into the outside air
mode. Any adjustment to the air intake must then be
made manually. Outside air should be used when trying
to defrost or defog windows to help reduce moisture
inside of the vehicle.
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
stale, be sure to return to the outside air mode
periodically.
3-24

?(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
to help cool the air inside your vehicle more quickly.
Press this button to turn the recirculation mode on or off.
When the button is pressed, an indicator light will
come on. The air-conditioning compressor also comes
on. The recirculation mode cannot be used with the
outside air mode.
When in the AUTO mode, the system automatically
selects recirculation to cool the vehicle's temperature.
By pressing this button, the system will lock into
recirculation mode. Any adjustment to the air intake
must then be made manually. Recirculation is not
available when using the defrost or defog mode because
outside air is needed to reduce moisture inside of the
vehicle.
Operating the system in the recirculation mode may
cause fogging of the vehicle's windows when the
weather is cold and damp. To clear the fog, switch the
system to either the defog or defrost mode and
increase the fan speed. To avoid re-fogging of the
windows, operate the system in the outside air mode.
Temperature Control:The DRIVER knob changes the
temperature on the driver's and passenger's side of
the vehicle. Turn the knob clockwise or counterclockwise
to manually increase or decrease the temperature
inside your vehicle. Whenever you turn this knob, thetemperature will be displayed for approximately ®ve
seconds along with the current fan speed and air
delivery mode.
The PASSENGER knob changes the temperature on
the passenger's side of the vehicle. When the knob is in
the 12 o'clock position, the passenger's temperature
is the same as the driver's. Turn the knob clockwise for
warmer air on the passenger's side or counterclockwise
for cooler air. If the driver-set temperature is set at
full cold 60ÉF (16ÉC) or full hot 90ÉF (32ÉC), turning the
PASSENGER knob has no effect because the system
is locked at a maximum setting.
#A/C (Air Conditioning):Press this button to
override the automatic system and turn the
air-conditioning system on or off. When A/C is pressed,
an indicator light in the button will come on to let you
know that the air conditioning is activated. When
in AUTO, the air-conditioning compressor will come on
automatically, as necessary.
Air conditioning does not operate at temperatures below
approximately 35ÉF to 40ÉF (2ÉC to 4ÉC). The air
conditioning cannot be turned off in defrost and defog,
as it helps to remove moisture from the vehicle. It
also helps to keep the windows clear.
3-25

You may notice a slight change in engine performance
when the air-conditioning compressor shuts off and
turns on again. This is normal. The system is designed
to make adjustments to help with fuel economy while
still maintaining the selected temperature.
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 recirculate mode.
3. Select the A/C.
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 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.Sensors
The solar sensor on your vehicle monitors the solar
radiation and uses the information to maintain the
selected temperature when operating in AUTO mode by
initiating needed adjustments to the temperature, the
fan speed and the air delivery system. The system may
also supply cooler air to the side of the vehicle facing
the sun. The recirculation mode will also be activated, as
necessary. Do not cover the solar sensor located on
the top right side of the instrument panel near the
windshield or the system will not work properly.
There is also a sensor located behind the front bumper.
This sensor reads the outside air temperature and
helps to maintain the temperature inside the vehicle.
Any cover on the front of the vehicle could give a false
reading in the temperature.
If the outside temperature goes up, the displayed
temperature will not change until:
·The vehicle's speed is above 16 mph (26 km/h) for
one and a half minutes.
·The vehicle's speed is above 45 mph (72 km/h) for
one minute.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.
3-26

There is also an inside temperature sensor located to
the left of the ignition switch. The automatic climate
control system uses this sensor to receive information,
so if you block or cover it, the system will not function
properly.
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. Use the defog mode to clear
the windows of fog or moisture and warm the
passengers. Use FRONT to remove fog or frost from
the windshield more quickly.
Press the MODE button until the defog mode appears
on the display.
-(Defog):This mode directs the air equally between
the windshield and the ¯oor outlets with a small
amount to the side window outlets. When you select this
mode, the system turns off recirculation and runs the
air-conditioning compressor unless the outside
temperature is at or below freezing. An indicator light in
the A/C button will come on to let you know that the
air-conditioning compressor is activated. The
recirculation mode cannot be selected while in the
defog mode.
1FRONT:Pressing this button directs most of the
air to the windshield, with a small amount directed to the
side window outlets. The light on the button will come
on and the digital display will show the defrost mode
symbol and fan speed when the front defrost mode is
being used. In this mode, the system will automatically
turn off the recirculation and run the air-conditioning
compressor, unless the outside temperature is at
or below freezing. An indicator light in the A/C button
will come on to let you know that the air-conditioning
compressor is activated. Recirculation cannot be
selected while in the defrost mode. Pressing this button
again will return the system to the last operating
mode and the air intake mode will be in outside air.
If the system is in FRONT defrost when you shut the
engine off, it will restart in FRONT defrost unless
the engine is off for longer than 40 minutes. If the engine
is off longer than 40 minutes, the system will restart in
the operating mode that was set prior to FRONT defrost
and the air intake mode will be in outside air. Do not
drive until all windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
The rear window defogger will only work when the
engine is running.
3-27

=REAR:Press this button to turn the rear window
defogger on. Be sure to clear as much snow from
the rear window as possible. An indicator light in the
button will come on to let you know that the rear window
defogger is activated.
The rear window defogger will automatically 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.
Your vehicle has heated outside rearview mirrors. The
mirrors will heat to help clear fog or frost from the
surface of the mirrors 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 tab located on the air outlets 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 area around the base of the instrument
panel console and air path under the seats clear
of objects to help circulate the air inside of
your vehicle more effectively.
3-28

Notice:Don't lubricate the power antenna.
Lubrication could damage it.
Notice:Before entering an automatic car wash,
turn off your radio to make the power antenna
go down. This will prevent the mast from possible
damage. If the antenna does not go down when you
turn the radio off, it may be damaged or need to
be cleaned. In either case, lower the antenna
by hand by carefully pressing the antenna down.
If the mast portion of your antenna is damaged, you can
replace it. See your dealer for a replacement kit and
follow the instructions in the kit.
Integrated Windshield and Rear
Window Antennas (Coupe)
The antennas in your vehicle are located in the
windshield and the rear window. The front connector is
at the top of the windshield and the rear antenna is
incorporated in the rear window defogger grid.
Notice:Do not apply aftermarket glass tinting with
metallic ®lm. The metallic ®lm in some tinting
materials will interfere with or distort the incoming
radio reception. Any damage caused to your
backglass antenna due to metallic tinting materials
will not be covered by your warranty.

Once you are moving on the freeway, make certain you
allow a reasonable following distance.
Expect to move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance. If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted. Reduce your speed
according to your speedometer, not to your sense
of motion. After driving for any distance at higher
speeds, you may tend to think you are going slower
than you actually are.
Before Leaving on a Long Trip
Make sure you're ready. Try to be well rested. If you
must start when you're not fresh Ð such as after a day's
work Ð don't plan to make too many miles that ®rst
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it's ready to go. If it needs
service, have it done before starting out. Of course,
you'll ®nd experienced and able service experts in GM
dealerships all across North America. They'll be
ready and willing to help if you need it.
Here are some things you can check before a trip:
·Windshield Washer Fluid:Is the reservoir full? Are
all windows clean inside and outside?
·Wiper Blades:Are they in good shape?
·Fuel, Engine Oil, Other Fluids:Have you checked
all levels?
·Lamps:Are they all working? Are the lenses clean?
·Tires:They are vitally important to a safe,
trouble-free trip. Is the tread good enough for
long-distance driving? Are the tires all in¯ated to the
recommended pressure?
·Weather Forecasts:What's the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
·Maps:Do you have up-to-date maps?

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can't see it or
smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will
help keep CO out.Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.
