The air conditioner and heater work
best
if you keep your windows closed
while using them.
e : Selects the force of air you want.
The fan is always running unless the

Air Conditioning Settings
There are three air conditioning settings.
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time your air
conditioner's compressor
will have to
run, which should help fuel economy.
MAX: Provides maximum cooling or
quick cool-down on very hot days. This
setting recirculates much
of the air
inside your vehicle, and it should not be
used for long periods because
the air
may become too cold and dry.
A/C: Use for normal cooling on hot
days. This setting cools outside air and
directs it through the instrument panel
outlets.
I 9 (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 warmed air
1
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 air conditioner positions, and in
(@ (Defrost) and ,> (Defog) when
the outside temperature is above 50°F
(IOOC). 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
compressor on and off to keep the
desired cooling and help fuel economy.

Non-Air Conditioning Settings
2 (Vent): This setting brings in the
outside air and directs it to the upper
portion of your body through the
instrument panel outlets.
A! (Heat): This setting directs
warmed air through the heater ducts.
The air conditioner compressor doesn’t
run in the non-air conditioning settings.
This reduces engine load, resulting in
improved fuel economy. If no non-air
conditioning setting maintains the
comfort of the air inside your vehicle, or
it causes your windows to fog
up, move
the right selector to
MAX or A/C, or
to
(@ (Defrost).
Defrosting
The setting (Defrost) directs most
air through the defroster vents, and
some through the heater ducts. Use this
for when you have fog or ice on the
windshield. When it’s
50°F (10°C) or
warmer outside, you’ll get cooled air.
Defogging Windows with
Standard Climate Control
Move the temperature control to --
maximum heat.
To quickly defog the windshield, set the
right selector to
(@ and turn the fan
control to
HIGH.
Use ~2 (Defog) for normal defogging
of the windshield.

Electronic Climate Control
(OPTION)
With this system, you can control the
ventilation, heating and air conditioning
in your vehicle, or you can use the auto-
matic setting.
The digital screen displays the outside
temperature, the inside temperature setting, the fan speed, and the heating
mode you have selected.
The air conditioner compressor operates
in all
AUTO setting positions, and in
(@ when the outside temperature is
above 49°F (9°C). 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 compressor on and off to keep the
desired cooling and help
fuel economy.
TEMP: Sets the interior temperature
you want. The temperature you set will
be displayed on the digital screen.
Once you set the temperature, the system
will
try to maintain the set tempera-
ture, whether or not you are using the
heating or cooling controls. But
if you
set the temperature for 60°F (16°C) or
90"
F (32" C), the fan will stay on HI
speed unless you select a different
speed.
AUTO: To allow the system to
automatically control the temperature,
air distribution and fan speed:
1. Set the temperature you want with the
2. Press the AUTO switch.
TEMP switch.
EXT. TEMP: Press to have the outside
temperature displayed on the digital
screen (unless the system is
off). Press
again to return to the inside temperature
setting. When the system is
off, the
outside temperature will be displayed.
Use the following controls when
AUTO
is not desired.
% : Sets the fan speed. Press the top
of the switch to raise the fan speed, the
bottom of the switch to lower the fan
speed.

5 Engine Accessory Drive Belt Inspection*-
Inspect the belt for cracks, fraying, wear and
proper tension. Replace as needed.
6 Cooling System Service*-Drain, flush and refill
the system with new or approved recycled coolant
conforming
to GM Specification 1825M. Keep
coolant at the proper mixture as specified. See the
Index under Coolant. This provides proper freeze
protection, corrosion inhibitor level and engine
operating temperature.
Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the radiator and air
conditioning condenser. Wash the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test
of both the cooling system and the
pressure cap.
