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.

ProCarManuals.com

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.
ProCarManuals.com

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
windows.

for your Buick, and how to get the best performance

A CAUTION:
Hearing damage from loud noise is almost
undetectable until
it is too'late. Your hearing
can adapt to higher volumes of sound. Sound
that seems normal can be loud and harmful to
-3ur hearing. Take precautions by adjusting
..re volume control on your radio to a safe
sound level before your hearing adapts to
it.
To help avoid hearing loss or damage:
1. Adjust the volume control to the lowest
-. Increase volume slowly until you hear

If No Steam Is Coming From Your-Engine:
If you get the overheat warning but see or hear no steam,
the problem
may not be too serious. Sometimes the
engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with
no sign of steam, try
this for a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan speed
and open the window as necessary.
3. Try to keep your engine under load (in a drive gear
where the engine runs slower). If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about ten minutes.
If the warning doesn’t come back on, you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine\

for two or three minutes while you’re parked, to
see if
the warning stops. But then, if you still have the warning,
TURN OFF THE ENGRVE AND GET EVERYONE
OUT
OF THE VEHICLE until it cools down.
You may decide
not to lift the hood but to get service
help right away.

Temperature-A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of heat
and
its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material'of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade
C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor
Vehicle Safety Standard
No. 109. Grades B and A
represent higher levels of performance on the laboratory
test wheel than the minimum required by law.
Warning: The temperature grade for
this tire is
established for a tire that is properly inflated and
not
overloaded. Excessive speed, underinflation, or excessive
loading, either separately or in combination, can cause
heat buildup and possible tire failure.
Those grades are molded on the sidewalls of'passenger
car tires.
While the tires available as standard or optional
equipment on General Motors vehicIes may vary with
respect to these grades, all such tires meet General
Motors performance standards and have been approved
for use
on General Motors vehicles. All passenger type
(P Metric) tires must conform to Federal safety
requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the, factory to give you the longest tire life and
best overall performance.
In most cases, you will not need to have your wheels
aligned again. However, if you-notice unusual tire wear
or your vehicle pulling one way or the other, the
alignment may need
to be reset. If you notice your
vehicle vibrating when driving on a
smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted.
If wheel nuts keep coming loose, the wheel, wheel bolts,
and wheel'nuts should be replaced. If the wheel leaks air
out, replace it (except some aluminum wheels, which can sometimes be repaired). See your Buick dealer
if any of
these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying
capacity, diameter, width, offset, and be mounted the same way as the one
it replaces.
