Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
TEMPERATURE:This lever is used to adjust the
temperature of the air coming through the system.
Moving the lever between COOL and WARM will change
the temperature of the air coming through your outlets.
9FAN:Move this lever to select the speed of
the fan. Moving the lever between LOW and HIGH will
decrease or increase the fan speed. The fan will be
off when the system is off.To change the current mode, select one of the following:
RECIRC (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 heat or 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. You may not use RECIRC with FRONT
defrost or BLEND.
VENT:This mode directs air to the instrument panel
outlets.
HTR (Heater):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.
BLEND:This mode splits the airow between the
windshield and the oor outlets. The air conditioning
compressor will be operating.
OFF:The ventilation system always allows fresh air to
ow through your vehicle when it is moving. The
system will try to keep the air at a previously chosen
temperature. When the system is off, the blower fan is
also off.
MAX (Maximum Air Conditioning):This mode directs
airow through the instrument panel outlets. The
amount of outside air entering your vehicle is limited.
3-24

Also in this mode, the RECIRC function is activated to
create the maximum cooling effect in the vehicle. If
RECIRC was activated before selecting MAX, the light
in the RECIRC button will go off. If RECIRC is
selected after MAX, the light in the RECIRC button will
not come on.
NORM (Normal Air Conditioning):This mode cools
the outside air entering your vehicle and directs it
through the instrument panel outlets.
BI-LEV (Bi-Level Air Conditioning):This mode directs
about 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. The air conditioning compressor is
on in this mode.
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 MAX.
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 the air inside of your vehicle, then uses the
information to maintain the selected temperature 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 in the
center of the instrument panel, near the windshield,
or the system will not work 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. This mode allows you to clear fog or
frost from your windshield.
3-25

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 75° F (24° 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 “Sensors” 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.
AIR FLOW:Pressing the AIR FLOW button will display
and hold the current setting while in manual mode.
3-27

Use the up and down arrows on the AIR FLOW button
to cycle through the available modes.
WINDSHIELD-FLOOR:This mode directs most of
the airow to the windshield with some airow to
the outboard outlets (for the side windows) and the
oor outlets.
MID:This mode directs airow through the
instrument panel outlets.
MID-FLOOR:This mode directs airow through both
the oor and the instrument panel outlets. There is
also a small amount of air directed to the windshield
and the outboard outlets (for the side windows).
FLOOR:This mode directs most of the airow to
the oor outlets with some directed to the outboard
outlets (for the side windows) and the windshield.
OFF:Press the OFF button once to turn off the
passenger climate control, if it has been activated.
Pressing the OFF button a second time will turn off the
main system. The outside temperature will be shown
on the display when the system is off.
VENT (Flow-Through Ventilation):Pressing the VENT
button allows outside air to ow through your vehicle
without the air conditioning compressor working. To turn
off the VENT selection, press the VENT button again.
Selecting the VENT and AUTO buttons at the same time
allows the system to control the airow automatically
without using the air conditioning compressor or
the recirculation mode.RECIRC (Recirculation):Press this button to limit the
amount of outside air coming into the vehicle. It can be
used to prevent outside air and odors from entering your
vehicle or to help heat or 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 recirculation mode cannot be used
with the FRONT defrost or VENT mode.
On hot days, open the windows to let hot 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, press the AUTO button
and the system will automatically enter recirculation
mode and the temperature will be at the full cold position
for maximum cooling.
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

1FRONT:Press the FRONT button to defrost the
windshield by directing airow toward the windshield and
outboard outlets (for the side windows). To turn off
FRONT, press the AUTO or AIR FLOW buttons.
If the AIR FLOW up button is pressed while in the
FRONT defrost mode, the system will direct the
air toward the instrument panel outlets. If the AIR FLOW
down button is pressed while in the FRONT defrost
mode, the system will direct the air toward the oor, and
the FRONT defrost mode will cancel. 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 or frost from the rear window.
=REAR:Press this button to turn the rear window
defogger on or off. Be sure to clear as much snow from
the rear window as possible.
At speeds above 35 mph (55 km/h), the defogger will
operate continuously until you press the REAR
button again. After 10 minutes of driving below 35 mph
(55 km/h), the defogger will turn off automatically. If
you need additional warming time, push the button
again. The system will then operate for ve minutes
before going off by itself.
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 defogger
button is pressed.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.

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, how much fuel you’re using, and many other things you’ll need to drive safely and economically.
Your vehicle is equipped with one of these instrument panel clusters, which includes indicator warning lights
and gages that are explained on the following pages.
Standard Cluster (United States version shown, Canada similar)

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for several seconds to remind people to
fasten their safety belts.
The safety belt light will
also come on and stay on
for several seconds,
then ash for several more.
If the driver’s belt is already buckled, neither the chime
nor the light will come on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG. The system checks
the air bag’s electrical system for malfunctions. The light
tells you if there is an electrical problem. The system
check includes the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic
module. For more information on the air bag system,
seeAir Bag Systems on page 1-47.This light will come on
when you start your
vehicle, and it will ash for
a few seconds. Then
the light should go out.
This means the system is
ready.
If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not inate in a crash, or they
could even inate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
3-36

Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
If your vehicle has the
standard instrument panel
cluster, this light will
come on if there is a
problem with your vehicle’s
engine oil pressure.
If your vehicle has the optional gage cluster, you can
read your oil pressure directly from the Driver
Information Center (DIC). SeeDIC Controls and
Displays on page 3-46.The oil pressure light will come on briey when you turn
your key to RUN. That’s just a check to be sure the
light works. This is normal and doesn’t show a problem.
If it doesn’t come on and then go off, be sure to have
it xed so it will be there to warn you if there is a
problem.
When this lightcomeson andstayson, and a chime
sounds, it means oil isn’t going through the engine
properly. The oil could be low, or there might be some
other oil problem. See your dealer for service.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
