shows the condition
of the charging
system. Readings between the red
warning zones indicate the
normal
operating range.
Readings in either red warning zone
indicate
a possible problem in the

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.

Heating and Venfilafion
When you don’t need to cool the outside
air, use these next settings.
You can
leave the air as it is or heat it.
The air conditioner compressor doesn’t
run in these settings. This reduces the
engine load, resulting in improved fuel
economy (gas mileage)
.
VENT: For mild outside temperatures,
when little heating or cooling is needed,
push
VENT. Air flow is through the
instrument panel outlets. Slide the
temperature control lever to a
comfortable level.
HEAT: When outside temperatures are
cold, push
HEAT. Slide the temper-
ature control lever to a comfortable
level. For maximum heating, slide it all
the way to the right.
This setting will send most of the heated
air through the ducts near the floor. The
rest will come out of the defroster vents
and side window defogger vents.
Defogging and Defrosting
There are two settings for clearing your
windows. For each setting, adjust the
temperature control
as desired. The air
conditioner compressor will run in
these settings to remove moisture from
the air when the temperature
is above
freezing.
tv th This setting allows half of
e air to flow to the floor
heater ducts, and half to
go to the windshield and
side window vents located
in the windshield pillars.
Use this setting to warm
passengers while keeping
the windshield clear. The
DEF setting directs 90% of
the air
through the defroster vents and the side
window vents, and
10% to the floor.

Electronic Climate Control
(OPTION)
This system allows you to set the
temperature you want. It also lets you
choose automatic air flow and direction
control, or air flow and direction
settings you select. Your vehicle
also
has the flow-through ventilation system
described later in this section.
The digital screen displays the outside
temperature, the inside temperature
setting and the fan speed.
When you select the
AUTO mode, the
air conditioner compressor will operate
if the outside temperature is above
freezing.

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.

Engine Overheating (CONTJ
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.
198
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 ab& 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.
f there's still no sign of steam, you can
dle the engine for two or three minutes
vhile you're parked, to see if the
varning stops.

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
vehicles 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
Oldsmobile 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.
If you need to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only with new GM
original equipment parts. This way, you
will be sure to have the right wheel,
wheel bolts, and wheel nuts for your
Oldsmobile model.
