Temperature Control conditioner’s compressor will have to do, which should
Move the TEMP slide control to change the temperature
of the air coming through your air outlets. Max
help fuel economy.
If you have the optional dual control air conditioner you
have a second temperature lever.
The top lever control the temperature for the driver. The
lower lever controls the temperature for the front seat
passenger. Both use the same mode and fan speed.
Air Conditioning
The air conditioning has three settings. On very hot
days, open
the windows long enough to let hot inside air
escape. This reduces the amount of work your
air
This 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
Use for normal cooling on hot days. This setting cools
outside air and directs
it through the instrument panel
outlets.
Bi-Lv (Bi-Level)
This setting is designed for use on sunny days where 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 front 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
40°F (4.5"C).
Ventilation
For mild outside temperatures, when little heating or
cooling is needed, press the
VENT button. Air will flow
through the instrument panel outlets. Use the air outlets
to turn on, adjust and turn off the air flow. Adjust the
TEMP lever to control the temperature.
Heating
When outside temperatures are cold, press the button
marked HTR and slide the
TEMP lever toward HOT to
send heated air through the floor outlets.
Defog
When your windshield is foggy, press the DEFOG
button to direct most of the air flow toward the
windshield. When it's
50°F (IOOC) or warmer, the
system will provide cooled air.
Defrost
. When fog or ice is on the
windshield, this setting
directs the maximum air
flow toward the windshield.
Operate the system
in another setting for 30 seconds
before pushing this button. This
will take moist air out
of the system to avoid fogging
of the windshield. When
it's 50" (10" C) or warmer the system will provide
cooled air.
Off
When the system is off, the ventilation system will allow
air to flow through your Buick when the vehicle is
moving.

Explanation of Scheduled Maintenance
Services
Below are explanations of the services listed in Schedule
I and Schedule 11.
The proper fluids and lubricants to use are listed
in
Section D. Make sure whoever services your vehicle uses
these. All
parts should be replaced and all necessary
repairs done before you or anyone else drives the vehicle.
NOTE: To determine your engine’s displacement and
code, see “Engine Identification”
in the Index.
1.
Engine Oil and Filter Change* -- Always use SH or
SG Energy Conserving I1 oils of proper viscosity. The
“SH” or “SG” designation may be shown alone or in
combination with others, such as “SH/CD,” “SH, SG,
CD,” “SG/CD” etc.
To determine the preferred
viscosity for your vehicle’s engine (e.g., SAE 5W-30-
or SAE 10W-30), see “Engine Oil” in the Index.
2. Chassis Lubrication -- Lubricate the transaxle shift
linkage, parking brake cable guides, underbody
contact points and linkage. If your vehicle is
equipped with grease fittings, lubricate the
suspension and steering linkage. 3.
4.
5.
Tire
and Wheel Rotation and Inspection -- For
proper wear and maximum tire life, rotate your tires
following the instructions
in this manual. See “Tires,
Inspection
& Rotation” in the Index. Check the tires
for uneven wear or damage. If you see irregular or
premature wear, check the wheel alignment. Check
for damaged wheels also.
Engine Accessory Drive Belt(s) Inspection -- Inspect
the belt(s) for cracks, fraying, wear and proper tension.
Replace as needed. (Belts can have small cracks
in
individual ribs without affecting performance).
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
“Coolant”
in the Index. 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.
