It takes a little more or less fuel to fill
up than the gage indicated. For
example, the gage may have indicated
the tank was half full, but it actually
took a little more or less than half the
tank's capacity to fill the tank.
The gage moves a little when you turn
a corner or speed up.
The tank is not necessarily empty
when the last bar goes out. There is a
1 to 1.5 gallon (4 to 5.6 L) fuel
reserve.
For your fuel tank capacity, see
Service
Station Information on the last page of
this manual.

Oil Pressure Gage (ELECTRONIC
J 1
CLUSTER)
Your oil pressure gage shows the oil
pressure in psi (pounds per square
inch) when the engine is running. Oil
pressure may vary with engine speed,
outside temperature and oil viscosity.
If you have a problem with your oil, the
box around the oil pressure symbol may
begin to flash
after you start your
engine, or when
you are driving. This
indicates that oil is not going through
your engine quickly enough to keep it
cool. The engine could be low on oil, or
could have
some other oil problem.
Have it
fixed right away.
NOTICE:
Damage to your engine fcom
neglected oil problems can be costly
and is not covered by your warranty.

The oil light could also flash on in three
other situations:
. When the ignition is on (in the Run
position) but the engine is not
running, the light will come on as a
test to show you it is working, but the
light will
go out when you turn the
ignition to
Start. If it doesn't come on
with the ignition on, you may have a
problem with the fuse. Have it fixed
right away.
Sometimes when the engine is idling
at a stop, the light may flash on and
off. This is normal.
If you make a hard stop, the light may
come on for a moment. This is normal.

A \
Voltmeter (ELEcmoNIc CLUSTER)
Your charging system gage will show
the rate of charge when the engine is
running. When the engine
is not
running but the ignition is on (in the
Run position), the display measures the
voltage output
of your battery, and will
flash until you turn the ignition to
Start.
The reading will change as the rate of
charge changes (with engine speed,
etc.), but readings between the warning
zones indicate the normal operating
range. Readings in either warning zone
indicate a possible problem with your
charging system. Have your Oldsmobile
serviced immediately. You
also have a warning light.
A box
around the battery symbol will flash
when the charging system needs
service.
If it comes on while you are driving, you
may have a loose belt or other problem
with the electrical charging system.
Have it checked right away. Driving
while this light is on could drain your
battery.
If
you must drive a short distance with
the light on, be certain to turn off all
your accessories, such as the radio and
air conditioner.

Engine Coolant Temperature Gage
pcmoNIc CLUSTER)
This gage has bars that show the engine
coolant temperature.
A box around the temperature symbol
will flash when your engine
is too hot.
It means that your engine coolant has
overheated. If you have been operating
your vehicle under normal driving
conditions, you should pull
off the road,
stop your vehicle and turn
off the
engine as soon as possible.

Brake System Warning Light
Your Oldsmobile’s hydraulic brake
system is divided into two parts.
If one
part isn’t working, the other part can
still work and stop you. For good
braking, though, you need both parts
working well.
If the warning light comes on, there
could be a brake problem. Have your
brake system inspected right away.
This light should come on as you start
the vehicle. If it doesn’t come on then,
have it fixed
so it will be ready to warn
you
if there’s a problem.
If the light comes on while you are
driving, pull off the road and stop
carefully.
You may notice that the pedal
is harder to push. Or, the pedal may go closer
to the floor. It may take longer to
stop.
If the light is still on, have the
vehicle towed for service. (See
Towing
Your Truck in the Index.)
The brake system warning light will also
come on when you set your parking
brake, and it will stay on
if your parking
brake doesn’t release fully. If it stays
on
after your parking brake is fully released,
it means you have a brake problem.

Anti-Lock Brake System Warning Light
With anti-lock, this light will go on
when you start your engine and may
stay on for several seconds. That’s
normal. If the light doesn’t come on,
have it fixed
so it will be ready to warn
you if there is
a problem.
If the light stays
on, or comes on when
you’re
driving, your Oldsmobile needs
service.
If the regular brake system
warning light isn’t
on, you still have
brakes, but you don’t have anti-lock
brakes. If the regular brake system
warning light is
also on, you don’t have
anti-lock brakes and there’s a problem
with your regular brakes. See
Brake
System Warning Light earlier in this part
Malfunction Indicator Lamp
(Service Engine Soon Light)
A computer monitors operation of your
fuel, ignition and emission control
systems. This light should come on
when the ignition
is on, but the engine
is not running, as a check to show you
it is working. If it does not come on at
all, have it fixed right away. If it stays
on, or it comes on while you are driving,
the computer is indicating that you
have a problem. You should take your
vehicle in for service soon.
NOTICE:
If you keep driving your vehicle
with this light on, after a while the
emission controls won’t work as
well, your fuel economy won’t be
as good and your engine may not
run as smoothly. This could lead
to costly repairs not covered by
your warranty.

LO HI
Climate Control System
Your vehicle's heater and air
conditioner work best
if you keep your
windows closed. Your vehicle also has
flow-through ventilation, described later
in this section, to bring outside air into
your vehicle.
3f Fan Lever: The lever at the top has
four positions. Move it toward
HI to
increase the air flow. To decrease the
air flow, move it toward
LO.
Temperature Lever: Slide the lever on
the left to control the temperature of the
air flow into the vehicle. Move the lever
up for warmer air, down for cooler air.
Function Lever: Slide the lever on the
right to select the function desired. The
air conditioner compressor will operate
in all settings except
VENT and HTR
(Heater) when the outside temperature
is above freezing. When the air
conditioner compressor cycles
on, you
may sometimes notice slight changes in
your vehicle's engine performance and
power. This is normal, because the
system is designed to keep the desired
cooling level and help fuel economy. There are
three air conditioning
settings:
MAX A/C, NORM A/C, and
BI-LEV A/C. On very hot days, your
vehicle will cool down more quickly and
economically in any of these settings
if
you open the windows long enough to
let hot inside air escape. For all settings,
adjust the temperature control lever and
fan speed as desired.
MAX A/C: Select this setting to get
maximum cooling or quick cool-down
on very hot days. This setting
recirculates much of the air inside your
vehicle. It should not be used for long
periods
of time because the air may
become too cold and dry.
Also slide the temperature control lever
down to the coolest setting and adjust
the fan speed as desired.
NORM A/C: Use this setting for
normal cooling on hot days. This setting
cools outside air and directs it through
the instrument panel outlets.
BI-LEV A/C: Use on cool but sunny
days. This setting brings in outside air,
but directs it two ways-through the
instrument panel outlets and the heater

ducts at your feet. At times this
temperature difference may be more
apparent than others.
VENT: The vent setting brings in
outside air through the instrument
panel outlets and at your front side
windows.
HTR The heater setting brings in most
heated air through the heater ducts, and
some through the defroster vents.
If you have the optional engine coolant
heater and use it during cold weather,
20°F (-8°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Coolant Heater.
most of the warmed air to the
windshield and side windows. Some
will also
go to the floor vents.
The air conditioner will also run in this
setting to remove moisture from the air
when the temperature is above
40°F
(4°C). Adjust the temperature control
as desired.
(Defrost): This setting directs
Defogging and Defrosting
To rapidly defrost the windshield, slide
the temperature control lever all the
way up and select the
(j@ setting.
Adjust the fan to the highest speed.
To rapidly defog the side windows,
select the
BI-LEV AfC setting and
adjust the fan to the highest speed. Aim
the side vents toward the side windows.
For increased air flow to the side vents,
close the center vents.

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 and console clear of objects.
This helps air to circulate throughout
your vehicle.
Audio Systems
The following pages describe the audio
systems available for your Oldsmobile,
and how to get the best performance
from them. Please read about the
system in your vehicle.
Hearing damage from loud noise is
almost undetectable until it is too late.
Your hearing can adapt to higher
volumes of sound. Sound that seems
normal can be loud and harmful to your
hearing. Take precautions by adjusting
the volume control on your radio to a
safe sound level before your hearing
adapts to it.
To help avoid hearing loss or damage:
1. Adjust the volume control to the
lowest setting.
2. Increase the volume slowly until you
hear comfortably and clearly.
NOTICE:
Before you add any sound
equipment to your vehicle
- like a
tape player, CB radio, mobile
telephone or two-way radio
- be
sure
you can add what you want. If
you can, it’s very important to do it
properly. Added sound equipment
may interfere with the operation
of
your vehicle’s engine, Delcom radio
or other systems, and even damage
them. And, your vehicle’s systems
may interfere with the operation of
sound equipment that has been
added improperly.
So, before
adding sound equipment, check
with your dealer and be sure to
check federal rules covering mobile
radio and telephone units.
