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.

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.
