If your Buick has the Dual Automatic ComforTemp
Climate Control option, it looks like this:
If you have this option,
you can adjust the direction of
the air
flow to the rear seating area. The
following information tells
you how it works.
You will hear a beep each time a button is pushed. The
display will show fan, temperature and mode settings.

Ext Temp
Push this and the display
will indicate the outside
temperature (unless
the
system is OFF). Push it
again to return to the
regular system display.

EXT.
TEMP
CoollWarm
To choose the temperature you want maintained inside
the car, push one of these.
You can choose from
60°F (16OC), for maximum
cooling, and
90 F (33 "C), for maximum heating. It is
not necessary to choose the extreme temperature to get
the system to heat
or cool at the maximum. The system
does it automatically.
Off
T 7
When the system is off, the
ventilation system will
allow air to flow through
your Buick when
the
vehicle is moving. The
system will try
to keep the
air at the chosen
temperature, unless it is
very hot
or very cold
outside. The outside
temperature will show in
the display area when the
system is
OFF.
120

Auto
When the system is set for
automatic, air will come
from the floor outlets, the
instrument panel outlets, or
both.
Fan speed will vary
(unless a blower
LO or HI
button has been pushed) as
the system gets to and
maintains the temperature
setting
you have selected.
Dual Zone
____
The front seat passenger
can control air temperature
in their seating area.
The display will show the set temperature and blower
speed.
In cold weather the system will delay turning on the fan,
to avoid blowing cold air. The length
of the delay
depends
on engine coolant temperature, outside
temperature, and time since the engine was last started.
Pushing a
LO or HI blower button will override this
delay, and cause the fan to start.
To rid the system of stale air in warm weather, air will
come out
of the floor outlets for a short time. The air temperature for
the right side of the front seat
can be set using the control on
the passenger’s door.
Both
DUAL ZONE and AUTO buttons will light up. To
turn off this part of the system , push the DUAL ZONE
button again.
121

PASSENBER CLIMATE CONTROL The right front seat
passenger
can also activate
the dual zone function by
pressing the
WARM or
COOL buttons on the
passenger door.
The indicator above the control will show the difference
from the main temperature setting.

To warm the air, press HTR
and adjust the temperature
and
fan speeds for your
comfort. Most of the air
will come from the floor
HTR E
outlets.
Defog
When the outside
temperature is mild, use
DEFOG to keep fog off the
windshield.

Air entering the car will be evenly split between the
floor outlets and
the outlets near the windshield.
The blower speed will be controlled automatically,
but
you can choose another fan speed by pushing the HI or
LO buttons.
Defrost
This setting will direct most
of the air flow toward the
windshield. Use this when
there is fog or ice on the
I windshield.
Defrost will work better if any ice and snow is cleared
from the hood and the air inlet area between
the hood
and
the windshield.
Blower speed will be controlled automatically, but
you
can choose another speed by pushing the HI or LO
buttons.
Rear Window Defogger (Option)
The lines you see on the
rear window warm the
glass. Press the button to
start warming your
window. After
10 minutes,
it will go
off by itself or,
pressing the button again
during the heating cycle
will shut it
off. If you need
additional warming time,
push the button again.
If you have the heated outside rearview mirror option,
the mirror will be warmed when the rear defogger is on.
I NOTICE:
Scraping the inside of your rear winoow could
cut and damage the heater. Your warranty wou’” not cover this damage. Don’t put decal? +here,
you might have to scrape them off.

If your Buick has this climate control system, the
following information tells you how it works.
Your Buick's flow through ventilation system supplies
outside air into
the vehicle when it is moving. When the
heater or air conditioning fan is running, outside air
will
also enter the vehicle.
Fan Speeds
The fan control is used to select the speed you want the
blower to control the air flow.
Lever Controls
The upper lever changes the fan speeds. The lower lever
changes the temperature
of the air coming through your
air outlets.
Air Conditioning
The next three selections cool the air. The air
conditioner won't work well unless all the windows are
closed. On very hot days, open the windows long
enough
to let hot inside air out. This reduces the amount
of work your air conditioner's compressor will have to
do, which should help fuel economy.
Max
This setting provides maximum cooling with the least
amount of work.
MAX recirculates much of the air
inside your vehicle
so it maximizes your air
conditioner's performance and fuel economy.
Norm
Use NORM for normal cooling on hot days. This setting
cools outside air and directs it through the instrument
panel outlets.
125

Bi-Level
This setting is designed for use on sunny days when the
air is only moderately warm or
cool. On days like these,
the sun may adequately warm your upper body, but your
lower body may
not be warm enough.
The Bi-level setting directs outside air into your vehicle
in two ways. Cool air is directed toward your upper
body through the instrument panel outlets, while slightly
warmed air is directed through the heater outlet at your
feet.
The air conditioner compressor operates in all Air
Conditioning positions and the Defrost position when
the outside temperature is above
48 OF (9OC).
When you don’t need to cool the outside air, use the
VENT, HEAT, or DEFROST settings. Adjust the
temperature control for comfort. You’ll get better fuel
economy (gas mileage) if you’re
not cooling the outside
air. When
you cool the air, your engine runs a
refrigeration compressor, and it has to work harder.
Vent
For mild outside temperature, when little heating or
cooling is needed, use the
VENT setting. Air will flow
through the instrument panel outlets. Use
the air outlets to
turn on, adjust and turn
off the air flow. Adjust the
temperature lever to the desired temperature.
Heater
When outside temperatures are cold, pressing the HTR
setting and adjusting the temperature lever
will send
warm air through the floor outlets, and some through the
defroster vents.
Def
The Defrost setting directs most of the air flow toward
the windshield. Use defrost when
you want to remove
fog or ice from
the windshield. When it’s 48 OF (9 “C) or
warmer, you’ll get cooled air.
Defog
Air entering the car will be evenly split between the
floor outlets and the outlets near the windshield. You
can control the temperature of the air and the fan speed
to clear the foggy windows.
126

Rear Window Defogger (Option)
The lines you see on the
rear window warm the
glass. Press the button to
start warming your
1 window. After-10 minutes it
will go off by itself, or
pressing the button again
during the heating cycle will shut it off. If you need
additional warming time,
push the button again.
Scraping the inside of your rear window could
cut and damage the heater. Your warranty would
not cover this damage. Don’t put decals there
you might have to scrape them
off.
Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out your system if you acquaint
yourself with it first. Find
out what your Delco @ system
can do and how
to operate all its controls, to be sure
you’re getting the most out of the advanced engineering
that went into
it.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about
10 to 40 miles (16 to 65 km). And,
tall buildings or hills can interfere with
FM signals,
causing the sound to come and go.
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble
to reduce this noise.

AM Stereo
This means the Delco@ system can receive C-QUAM@
stereo broadcasts. Many
AM stations around the country
use C-QUAM@ to produce stereo, though some
do not.
(C-QUAM@ is
a registered trademark of Motorola, Inc.)
If your D~ICO@ system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it.

-- like a tape player, CB radio, mobile
telephone or two-way radio
-- be sure you car
add what you want.
If you can, it’s very important
to
do it properly. Added sound equipment may
