Your Buick Comfort Control
Syst m -
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.
Lever Controls: The upper lever changes the functions
of your system. The lower lever changes the temperature
of the air coming through the system.
3f : Selects the force of air you want.
Air Conditioning
The upper lever has three air conditioner settings. 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: Provides maximum cooling with the least amount
of work. This setting recirculates much of the air inside
your vehicle
so it maximizes your air conditioner's
performance and
fuel economy.
NORM (Normal): Use for normal cooling on hot days.
This setting cools outside air and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use this 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 is directed through the heater ducts and
defroster vents. At times
this temperature difference may
be more apparent than others.
To turn the 5x1 off, move the upper lever to the OF'F position.

The air conditioner compressor operates in all AIR COND
positions, and in DEF (Defrost) when the outside
temperature is above about 40°F (4.5"
C).
Ventilation
For mild outside temperatures, when little heating or
cooling is needed, slide the upper lever to
VENT. Air
flow is through the instrument panel outlets. Rotate the
control next to the outlets to turn on, adjust or
turn off
the air flow. Adjust the lower lever on the control panel
to the temperature desired.
Heating
When outside temperatures are cold, sliding the upper
lever to
HEATER and the lower lever to HOT will send
heated air through the heater ducts, and some through the
defroster vents.
VENT and HEAmR are labeled
ECONOMY positions because the air conditioner
compressor doesn't run
in these two settings. This
reduces engine load, resulting
in improved he1 economy.
If either setting fails to keep you comfortable, or causes
your windows
to fog up, slide the upper lever to one of
the
AIR COND positions, or to DEF (Defrost).
Defrosting
The DEF setting directs most of the air through the
defroster vents, and some through the heater ducts.
Defogging Windows with Four Season
Climate Control
To quickly defog the windshield, set the upper lever to
DEF and move the hn switch to HI. Slide the lower
lever
to HOT.
In damp, cool weather (temperatures about 45"-65"F,
7"- 18" C), you can use BI-LEV to defog the side windows.
Set the upper lever to
BI-LEV and the fan switch to HI.
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.
In winter, it can
also keep ice from forming
on the rear window.
Press the
ON portion of the
switch. The indicator light
will glow. The rear window
defogger will
turn off
automatically after about
10
minutes of use. You can
also turn
it off by turning
off the ignition or pressing the
OFF portion of the
switch.

Keep the air path under the front seats clear of objects.
Do not attach a temporary vehicle license across the
defogger grid
on the rear window.
Flow-Through Ventilation System
Your Buick'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.

HI 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

that seems normal can be loud and harmful to

sound level before your hearing adapts to

F'M Stereo
FM Stereo will give you the best sound, but FM signals
will reach only about
10 to 40 miles (16 to 65 km). 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 inkfiere with each other. AM can also pick up
noise from things like storms and power lines.
To lower
this noise, try reducing the treble level.
AM Stereo
Your Delco@ system may be able to 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 Delco@ system can get C-Quam@ signals, your
stereo indicator light will come on when you are
receiving it.
