Your Buick Comfort Control System
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.
The lever next to the fan symbol selects the force of air
you want.
To turn the fan off, move the upper lever to the OFF
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, and directs it in
two ways. The cool air is directed to the upper portion
of your body through the instrument panel outlets, and
warmed air 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
Conditioning positions, and in Defrost when the outside
temperature is above about 40°F (4.5"C).
position.

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 HEATER are labeled
ECONOMY 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, slide the upper lever
to one of the Air Conditioning positions, or to DEF
(Defrost).
Defrosting
The DEF setting directs most of the air through the
defroster vents, and some through the heater ducts.
Defog
To quickly defog the windshield, set the upper lever to
DEF and move the fan switch to HI . Slide the lower
lever to
HOT.
In damp, cool weather (temperatures about 45 "-65"F,
7"- 1 8"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.
I NOTICE:
Don’t use a razor blade or somerning 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.
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.
When you enter a vehicle in cold weather, turn the
blower fan
to 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.
Keep the air path under the front seats clear of
objects. This helps air to circulate throughout your
vehicle.

If your vehicle starts to slide, ease your foot off the
accelerator pedal and quickly steer the way you want the
vehicle to
go. If you start steering quickly enough, your
vehicle may straighten out. Always be ready for a
second skid
if it occurs.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is
on the road. For safety, you’ll
want to slow down and adjust your driving to these
conditions. It is important
to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best
to avoid sudden steering, acceleration, or
braking (including engine braking by shifting to a lower
gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery
until your
vehicle is skidding. Learn to recognize warning clues --
such as enough water, ice or packed snow on the road to
make a “mirrored surface’’
-- and slow down when you
have any doubt.
Remember: Any anti-lock braking system
(ABS) helps
avoid only the braking skid.
Driving at Night
Night driving is more dangerous than day driving. One
reason is that some drivers are likely to be impaired
-- by
alcohol or drugs, with night vision problems, or by fatigue.
Here are some
tips on night driving.
0 Drive defensively.
0 Don’t drink and drive.

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 ENGINE AND GET EVERYONE
OUT OF THE VEHICLE until it cools down. When you
decide it's safe to
lift the hood, here's what
you'll see:
(A) Coolant recovery tank
(B) Radiator pressure cap
(C) Electric engine fan
You may decide not to
lift the hood but to get service
help right away.
