Voltmeter Gage
fl u VOLTS
When your engine is not
running, but the ignition
is
on (in the RUN position),
this gage shows your
battery’s state of charge in
DC volts.
When the engine
is running, the gage shows the
condition
of the charging system. Readings between the
low and high warning zones indicate the normal
operating range. Readings
in the low
warning zone may occur when a
large number
of electrical accessories are operating in
the vehicle and the engine is left at
an idle for an
extended period. This condition
is normal since the
charging system
is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with the reading in
either warning zone.
If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate
a possible
problem in the electrical system. Have
the vehicle
serviced
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
briefly when you
turn the
ignition key to
RUN. If it
doesn’t come on then,
have
it fixed so it will be
ready
to warn you if there’s
a problem.
A CAUTION:
-
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident. If the light
is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed
for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light
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.
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 Vehicle”
in the Index.)

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light
will come
on when you start your
ANTI - LOCK engine and may stay on for I
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 section.
The anti-lock brake system warning light should come
on briefly when you turn
the ignition key to RUN. If the
light doesn’t corne on then, have
it fixed so it will be
ready to warn you
if there is a problem.
Engine Coolant Temperature Gage
I
This gage shows the engine
coolant temperature.
If the
gage pointer moves into the
red area, your engine
is
too hot!
TEMP
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.
In “Problems on the Road,” this manual shows you what
to do. See ”Engine Overheating’‘
in the Index.

Malfunction Indicator Lamp (Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your Oldstnobile is
equipped
with a computer
which monitors operation
of the fuel, ignition and
emission control systems.
This system is called
OBD IT (On-Board
Diagnostics-Second Generation) and
is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping
to produce a cleaner
environment. The SERVICE ENGINE SOON light
comes on
to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle. This
system is
also designed to assist your service technician
in correctly diagnosing any malfunction.
I NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work
as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on! as a check to show you it is
working, when the ignition is on and the engine is not
running.
If the light doesn’t come on, have it repaired.
This light will also come on during a mal.function in one
of two ways:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Retailer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Retailer or qualified service center diagnosis and
service may be required.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see
“If
the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key
off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
retailer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle‘?
If so, reinstall the fuel cap, making sure to fully install
the cap.
The diagnostic system can determine if the fuel
cap has been left off or improperly installed. A loose or
missing fuel cap will allow fuel to evaporate into the
atmosphere.
A few driving trips with the cap properly
installed should turn the light off.
Did you just drive through a deep puddle of water?
If so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.

Have you recently changed brands of fuel‘?
If so, be sure to fuel your vehicle with quality fuel (see
“Fuel” in the Index). Poor fuel quality will cause your
engine not
to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when you
put the vehicle into gear, misfiring, hesitation
on
acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will
be detected by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
have your retailer or qualified service center check the
vehicle. Your retailer has
the proper test equipment and
diagnostic tools to fix any mechanical
or electrical
problems that may have developed.
Engine Oil Pressure Gage
OIL 0-
The oil pressure gage shows
the engine 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, but readings above the
low pressure zone indicate the normal operating range.
2-59
ProCarManuals.com

A reading in the low pressure zone may be caused by a
dangerously low oil level or other problems causing low
oil pressure.
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your
oil as soon as possible and have yo1
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored
in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren’t,
they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. If you notice a reduction in sound
quality, try
a known good cassette to see if it is the tape
or the tape player at fault.
If this other cassette has no
improvement in sound quality, clean the tape player.
Cleaning may be done with
a scrubbing action,
non-abrasive cleaning cassette
with pads which scrub
the tape head
as the hubs of the cleaner cassette turn. It
is normal for the cassette to eject while cleaning. Insert
the cassette at least three times to ensure thorough
cleaning.
A scrubbing action cleaning cassette is
available through your Oldsmobile retailer.
You may also choose
a non-scrubbing action, wet-type
cleaner which uses
a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette
will not
eject and, it may not clean as thoroughly as the
scrubbing type cleaner. Cassettes are subject to wear and the sound quality
may
degrade over time. Always make sure the cassette tape is in
good condition before you have your tape player serviced.
Care of Your Compact Discs
Handle discs carefully. Store
them in their original cases
or other protective cases and away from direct sunlight
and dust.
If the surface of a disc is soiled, dampen a
clean, soft cloth in a mild, neutral detergent solution and
clean
it, wiping from the center to the edge.
Be sure never to touch the signal surface when handling
discs. Pick
up discs by grasping the outer edges or the
edge of the hole and the outer edge.
Fixed Mast Antenna
The fixed mast antenna can withstand most car washes
without being damaged.
If the mast should ever become
slightly bent, you can straighten
it out by hand. If the
mast is badly bent,
as it might be by vandals, you should
rep1 ace
it .
Check every once in a while to be sure the mast is still
tightened
to the fender.
