Mode Knob
The right control knob changes the functions of your
system.
MAX: Use for maximum cooling. This setting
recirculates much of the air inside your vehicle. 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.
9 BI-LEVEL: Use on cool, but sunny days. This
setting brings in the outside air, but directs it in two
ways. Cooler 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.
2 VENT Use when outside temperatures are mild,
and little heating or cooling is needed. Airflow is
through the instrument panel outlets. Set the center
control knob to the temperature desired.
‘!A HEATER: This setting brings heated air through
the heater ducts, and some through the windshield
defroster vents.
If you have the optional engine coolant heater (engine
block heater) and use it during cold weather,
0°F
(- 18 O C) or lower, your heating system will more quickly
provide heat because the engine coolant is already
warmed. See “Engine Coolant Heater” in the Index.
9 BLEND: This setting divides airflow equally
between the heater ducts and the windshield defroster
vents.
DEFROST This setting directs air through the
windshield defroster vents located on top of the
instrument panel.

Air Conditioning Heating
Turning
the right control knob to HEATER and the
center control knob clockwise sends some heated air
through the heater ducts toward your feet, and some
through the defroster vents.
On very
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, which should help fuel
economy.
For quick cool-down on very hot days, use MAX with
the temperature knob all the way in the blue area.
If the
setting is used for long periods of time, the air in your
vehicle may become too dry.
For normal cooling on hot days, use
NC with the
temperature knob in the blue area. The system will bring
in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough. You
can use
BI-LEVEL with the temperature knob in the
middle. The system will bring in outside air and direct
it
to your upper body, while sending slightly warmed air to
your lower body. You may notice this temperature
difference more at some times than at others. 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 DEFROST.
If you have the optional engine coolant heater
(engine block heater) and use
it during cold weather,
0 “F (- 18 O C) or lower, your heating system will more
quickly provide heat because the engine coolant is
already warmed. See “Engine Coolant Heater” in
the Index.

Defrosting and Defogging
To defrost the windshield, turn all three control knobs to
the far right.
The DEFROST setting directs air through the defroster
vents located on top
of the instrument panel.
To warm passengers while keeping the windows clean,
use BLEND.
To defog the side windows, turn the right control knob
to BI-LEVEL and the fan control
knob to HIGH. Aim
the side vents toward the side windows. For increased
aifflow to the side vents, close the center vents.
Rear Window Defogger (If Equipped)
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 rnph (70 km/h),
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.
I NOTICE:
Don’t use a razor blade or anything 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.

Ventilation System
Use when outside temperatures are mild, and little
heating or cooling
is needed. Turn the right knob to
VENT. Airflow is directed through the instrument panel
outlets. Set the center knob to the temperature desired.
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.
Adjust the direction
of
airflow by moving the
louvered vents.
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 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 the highest position 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.
Keep the air path under the front seats clear of objects.
This helps air to circulate throughout your vehicle.

Playing a Cassette Tape
Your tape player is built to work best with tapes that are
30 to 45 minutes long on each side. Tapes longer than
that are so thin they may not work well in this player. While the tape is playing, use the VOL,
FADE, BAL,
BASS and TREB controls just as you do for the radio.
The display will show an arrow to show which side of
the tape is playing. When the down indicator arrow is
lit, selections listed on the bottom side
of the cassette
are playing. When the up arrow is lit, selections listed
on the top side of the cassette are playing. The tape
player automatically begins playing the other side when
it reaches the end of the tape.
If E and a number appear on the radio display, the tape
won’t play because of an error.
0 E10: The tape is tight and the player can’t turn
the tape hubs. Remove the tape. Hold the tape with the open end down and try to turn the right hub
counterclockwise with a pencil. Turn the tape over
and repeat.
If the hubs do not turn easily, your tape
may be damaged and should not be used in the
player. Try a new tape to make sure your player is working properly.
Ell: The tape is broken. Try a new tape.
If any error occurs repeatedly or if an error can’t be
corrected, please contact your dealer.
If your radio
displays an error number, write it down and provide it
to your dealer when reporting the problem.
