control and audio systems offered with your Pontiac. Be
sure to read about the particular systems supplied with
your vehicle.
Comfort Controls
This section tells you how to make yo'ur air system
work
for you. Your comfort control system uses
ozone-friendly R- 134a refrigerant.
With these systems, you can control the heating,
cooling and ventilation in your Pontiac.
Your vehicle
also has a flow-through ventilation system described
later in this section. Fan Knob
The left knob is the fan knob and selects the force of
air you want. Turn the knob clockwise to increase fan
speed and counterclockwise to decrease fan speed. The
fan
will always run unless the right control knob is
turned to
OFF. The fan must be on to run the air
conditioning compressor.

Electronic Climate Control System (Option)
Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up arrow to increase fan speed and the down
arrow to decrease fan speed.
Temperature Button
The TEMP button changes the temperature of the air
coming through the system. Press the up arrow for
warmer air and the down arrow for cooler air.
Mode Button
Press this button to deliver air through the floor, middle
or windshield outlets. The system will stay in the
selected mode until the
MODE or AUTO button is
pushed. Press the up
arrow to cycle through the
available modes.
Automatic Operation
When the system is set for AUTO, sensors will control
the
air delivery mode. Air will come from the floor,
middle and windshield outlets. The fan speed will vary
as the system maintains the selected temperature setting.
To find your comfort zone, start with 75°F (24°C)
temperature setting, allow about 20 minutes for the
system to regulate. Press the TEMP button up or down
to adjust the temperature setting
if necessary. If you
choose the temperature setting
of 60°F (15 "C), the
system
will remain at that maximum cooling setting
and
will not regulate the fan speed. If you choose the
temperature setting of
90°F (33 O C), the system will
remain at that maximum heating setting and will not
regulate the fan speed. Choosing either
maximum
setting will not cause the system to heat or cool
any faster.

Pressing the AUTO button will display the requested
temperature, fan speed'and
air delivery mode for five
seconds, then change to display the outside air
temperature. Be careful not to put anything over the
sensor located in the middle
of the instrument panel near
the windshield, or over the sensor
in the gnlle above the
radio. These sensors are used by the automatic system to
regulate temperature.
The exterior temperature display sensor is in front
of the
car, near the radiator. This displayed temperature is most
accurate when the vehicle
is moving. During stops, or
while idling, the display shows the previous driving
temperature for best system control.
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 outside air temperature,
engine coolant temperature, and time since the engine
was last started. Pushing the
fan button will override this
delay and change the fan to a selected single speed.
If you leave your vehicle, the system will remember the
control setting the next time you start your engine.
Manual Operation
You may also manually adjust the delivery mode or
fan speed.
'!! HEAT: Manually selecting HEAT by cycling
through the
MODE settings will deliver air to the floor
outlets.
+# DEFOG: Manually selecting DEFOG by cycling
through the
MODE settings will deliver air to the floor
and windshield outlets.
12 BI-LEVEL: Manually selecting BI-LEVEL by
cycling through the MODE setting will deliver warm air
to the floor and cooler air to the middle instrument panel outlets.
OFF: Press this button to turn the system off. Fresh air
will continue to flow through the vehicle, and the
system
will try to maintain the previously set
temperature. The outside temperature will show in the
display when the system
is OFF.

A/C: Press this button to turn the air conditioning
on and
off. The system will cool and dehumidify the
air inside the vehicle.
In the AUTO mode, the display
will show that
A/C is active, but the air conditioning
compressor
only operates when the system determines
it
is needed.
RECIRC,: Press this button to limit the amount of fresh
air entering your vehicle. You may use this setting to
limit odors entering your vehicle. Press
REClRC to
change to a manual
MODE and air will recirculate for
10 minutes. RECIRC will show on the display and then
return to
EXT TEMP display.
DEFROST: Press this button to clear the windshield.
The system will automatically control the fan speed
if
you select defrost from AUTO.
OF O C: ‘Press this button to display the temperature in
degrees Fahrenheit or Celsius.
Air Conditioning
On hot days, open the windows long enough to let hot
inside
air escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
If you have the standard system, for quick cool-down on
very hot days,
use MAX with the temperature knob in
the blue area. If this setting is used for long periods of
time, the air in your vehicle may become too cold and
dry. For normal cooling on hot days, use A/C with the
temperature
knob in. the blue area. This setting cools the
air entering your vehicle and directs it through the
instrument panel outlets.
If you have the electronic system, press the A/C button
to
turn the system on. The system will cool and
dehumidify the air inside the vehicle.
Also while in
AUTO mode, the system will use FtECIRC as necessary
to cool the air.
&1 cool but sunny days, with the standard system through
manual operation of the electron& system, use BI-LEVEL
to deliver warm air to the floor and cooler air to the
middle instrument panel outlets. To warrn or cool the
air
delivered, push the TE- button up or down.
When the air conditioner is on, you may sometimes notice
slight changes
in your vehicle’s engine speed and power.
This is normal because the system is designed to cycle the
cornpressor on
and off to keep the desired temperature.

Heating
If you have the standard system, on cold days use
HEATER with the temperature knob in the red area. If
you have the electronic system, press AUTO and adjust
the temperature by
p;essing the TEMP up or down
arrow. You may also adjust the electronic system
manually by pressing the
MODE button and selecting
HEAT. Again, adjust the temperature by pressing the
"EMF up or down arrow.
With each system, outside air
will be brought in and sent
through the
floor outlets. The heater works best if you
keep your windows closed while using it.
Ventilation System
For mild outside temperatures when littkheating or
cooling is needed, use
VENT (on the standard system)
to direct outside air through your vehicle. Air will flow
through the middle instrument panel outlets.
Your vehicle's flow-through ventilation system supplies
outside
air into the vehicle when it's moving. When the
vehicle
is not moving, you can get outside air to flow
through
by selecting any air choice (except the rear
,window defogger) and any fan speed. Your
vehicle has air outlets that allow
you to adjust
the direction and amount
of airflow inside the vehicle.
Push the outlet up or down to direct airflow to your
preference. Increase or reduce the amount of airflow by
opening and closing the louvers. Opening and closing
the louvers will
also direct airflow from side-to-side.
ProCarManuals.com

If you have the rear seat passenger outlet, it's attached to
the back
of the console. You can adjust the airflow
toward either seating area, the floor or upward. Turn the
end
knobs up and down to direct airflow. Increase or
reduce
the amount of airflow by opening and closing the
louvers. Opening and closing the louvers will also direct airflow from side-to-side.
Ventilation Tips
0 Keep the hood and front air inlet free of ice, snow or
any other obstruction such as leaves. The heater and
defroster will work better, reducing the chance of
fogging your windows.
0 When you enter a vehicle with the standard system in
cold weather, select
HEATER to supply air through the
floor outlets. Then
turn the fan on high for a few
moments before driving away. This will blow moist air
from the intake outlets toward the floor, not the
windshield. It reduces
the chance of fogging your
windows. If you have the electronic system, the AUTO
setting will do this for you. Manual operation of the
electronic system in the
HEAT' mode will also supply
air through the floor outlets.
0 Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.
0 When the engine idles for a long time, the exterior
temperature sensor may cause the system to blow
air
that is too cool. Once the vehicle is moving again the
system will
try to maintain the set temperature inside
your vehicle.
