Climate Control
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.
OFF: Press to turn the blower off.
Some air will still come from the outlets
at the floor. Press any function button
to turn the system
on.
Temperature Control Lever: This
lever changes the temperature of the air
coming through the system. The higher
the lever setting, the warmer the air.
3f: Selects the force of air you want.
Press
LO to lower the fan speed, HI to
raise
it.
Air Conditioning
On very hot days, open the windows
long enough to let hot inside air escape.
This reduces the time it tales for your
vehicle to cool down, which should help
fuel economy.
There are three air conditioning
settings:
MAX: Provides maximum cooling or
quick cool-down
on very hot days. This
setting also helps prevent outside odors
from entering your vehicle.
This setting recirculates much of the air
inside your vehicle, and it should not be
used for long periods because the air
may become too cold and
dry. This
setting is not recommended if an
occupant is smoking.
NORM: Use for normal cooling on hot
days. This setting brings in outside air,
cools it and directs it through the
instrument panel outlets.
BI-LEV (Bi-Level): Use 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 most
warmed air is directed through the
heater ducts and a little to the defrost
and side window vents. At times this
temperature difference may be more
apparent than others.

temperature caused by sunlight. To
keep you comfortable, it reduces the
interior temperature by as much as 5°F
(3°C) below the setting
on the digital
screen.
AUTO: To allow the system to
automatically control the temperature,
air distribution and fan speed:
1. Set the temperature you want with
the
COOL/WARM switch.
2. Press the AUTO switch. The AUTO
symbol will appear on the digital
screen.
The system will approach the
temperature you select as quickly as
possible. For most efficient operation,
just set the system temperature where
you would like it and drive away.
OUTS TEMP: Press to have the
outside temperature displayed on the
digital screen. Press again to return to
the inside temperature setting.
If the system is left in the outside
temperature mode, the outside
temperature will be displayed except
when changing the inside temperature
setting using the
COOL/WARM
switch. The display will return to the
outside temperature setting in about
five seconds. Use
the following controls when the
system is not set on
AUTO:
8: Press the top of the switch to raise
the fan speed, the bottom of the switch
to lower the fan speed. The fan symbol
and bar graph will be displayed on the
digital screen.
When the
AUTO switch is pressed, the
fan symbol will go out and the fan will
return to automatic operation.
If the Fahrenheit (F") or Celsius (C")
symbol begins to flash, or flashes when
you turn on the ignition,
it indicates an
electrical problem with your air conditioning system. The flashing
will
continue for about two minutes. It
means
you should have your system
serviced.

Flow-Through Ventilation System
Your Oldsmobile'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, set the blower fan to the
highest setting 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.
