Comfort Controls
This section tells you how to make your 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.
Standard Climate Control System
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 b'e on to run the air
conditioning compressor.
Temperature Knob
The center control regulates the temperature of the air
coming through the system. Turn it toward the blue area
for cooler air. Turn it toward the red area for warmer air.
Mode Knob
The right control has settings for air conditioning and
non-air conditioning modes. The mode control allows
you to choose
the direction of air delivery.

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 RECIRC as necessary
to cool the air.
On cool but
sunny days, with the standard system or
through manual operation
of the electronic system, use
BI-LEVEL to deliver warm air to the floor and cooler air
to the middle instrument panel outlets. To warm or cool
the air delivered, push
the TEMP button up or down.
When the air conditioning system is in
AUTO mode,
the
A/C light will always be on. When the ambient
-/
temperature outside the vehicle reaches 40°F (4" C),
the compressor will remain on continuously.
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 pressing the
TEMP up or down
arrow. You may also adjust the electronic system
nmnually
by pressing the MODE button and selecting
HEAT. Again, adjust the temperature by pressing the
TEMP 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 little heating 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.
