Defogging Windows
To defog the windshield, turn all three
control knobs to the far right.

Air Conditioning System
(OPTION)
The air conditioner and heater work
best if you keep your windows closed
while using them. Your vehicle also has
the flow-through ventilation system
described later
in this section.
3f : The left control knob sets the
fan speed. To select the force
of air you
want,
turn the knob. The fan is always
running unless the mode control is
moved to
OFF.
Temperature Control: The center
control knob regulates the temperature
of the air coming through the system.
Mode Control: The right control knob
changes the functions
of your system.
Air Conditioning
Your system has three air conditioner
settings. Before using your air
conditioner on very hot days, open the
windows long enough
to let hot inside
air escape. This reduces the amount
of
work your air conditioner's compressor
will have to do, which should help fuel
economy.
MAX: Use for maximum cooling. This
setting recirculates much
of the air
inside your vehicle
so it maximizes your
air conditioner's performance and your
vehicle's fuel economy.
A/C: Use for normal cooling on hot
days. This setting cools outside air and
directs it through the instrument panel
outlets.

Air Conditionina (CONI) -.
qg (Bi-Level): Use on cool, but
sunny days. This setting brings in the
outside air, but directs it in two ways.
The cool air is directed to the upper
portion of your body through the
instrument panel outlets, but slightly
warmer air is directed through the
heater ducts and defroster vents. At
times this temperature difference may be
more apparent than others.
The air conditioner compressor operates
in all three air conditioning positions. It
also operates in (Defrost) when
the outside temperature is higher than
about
40°F (4.5"C).
Ventilation
Use when outside temperatures are
mild, and little heating or cooling is
needed. Turn the right control knob to
2 (Vent). Air flow is directed
through the instrument panel outlets. Set
the center control knob to the
temperature desired.
Heating
Turning the right control knob to
72 (Heater) and the center control
knob clockwise will send heated air
through the heater ducts, and some
through the defroster vents.
3 (Vent) and (Heater) are
economical positions because the air
conditioner compressor doesn't run in
these two settings. This reduces engine
load, resulting in improved fuel
economy. If either setting fails to keep you
comfortable, or causes your windows
to fog up, turn the right control knob to
one of the air conditioning positions, or
to
(j@ (Defrost).
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Block Heater.
flow equally between the heater ducts
and the windshield defroster vents.
vg (Blend): This setting divides air
Defrosting
The (@ (Defrost) setting directs most
air through the defroster vents, and
some through the heater ducts.

Defogging Windows with
Air Conditioning System
To defog the windshield, turn all three
control knobs to the far right. To defog
the side windows, turn the
right control knob to 12 (Bi-Level)
and the fan control knob to
HIGH. Aim
the side vents toward the side windows.
For increased air flow to the side vents,
close the center vents.
Rear Window Defogger (OPTION)
The rear window defogger uses a
warming grid to remove fog from the
rear window. Press
the defogger switch.
The indicator light will glow.
If your
vehicle is traveling under
45 mph
(70 kmlh), the rear window defogger
will turn off automatically after about
10 minutes of use. If your vehicle is
traveling over
45 mph (70 km/h), the
defogger will operate continuously. You
can
turn the defogger off by turning off
the ignition or pressing the switch again.
Do not attach a temporary vehicle
license across the defogger grid
on the
rear window.

Rear Window Defogger (CONT.:) I Flow-Through Ventilation System
Don’t use a razor blade or something
else
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 Your Pontiac’s
flow-through ventilation
system supplies outside air into the
vehicle when it is moving. Outside air
will also enter the vehicle when the
heater or the air conditioning fan is
running.
Ventilation Tips
Keep the hood and front air inlet free
of ice, snow, or any other obstruction
(such as leaves). The heater and
defroster will work far better, reducing the chance of fogging the inside of
your windows.
When you enter a vehicle in cold
weather,
turn the fan control knob to
HIGH for a few moments before
driving off. This helps clear the intake
ducts of snow and moisture, and
reduces the chance of fogging the
inside of your windows.
clear of objects. This helps air to
circulate throughout your vehicle.
Keep the air path under the front seats
