Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people
to
fasten their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay
on
until the driver’s belt
is buckled.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows the words AIR BAG. The system
checks the air bag’s electrical system for malfunctions.
The light tells you if there is an electrical problem. The
system check includes the air bag sensors, the air bag
module, the wiring and the diagnostic module.
For more
information
on the air bag system, see “Air Bag” in
the Index.
AIR BAG
You will see this light flash
for a few seconds when
you
turn your ignition to RUN
or START. Then the light
should go out. This means
the system is ready.
If the air bag readiness light doesn’t come on when you
start your vehicle,
or stays on, or comes on when you
are driving, your air bag system may not work properly.
Have your vehicle serviced right away.

Voltmeter Brake System Warning Light
Irn
18 /
Your charging system gage will show the rate of charge
when the engine is running.
The reading will change
as the rate of charge changes
(with the engine speed, etc.), but readings between the
red warning zones indicate the normal operating range.
Readings
in either red zone indicate a possible problem
with your charging system. Have your Oldsmobile
serviced immediately.
When the engine
is not running, but the ignition is on (in
the RUN position), the display measures the voltage
output
of your battery. 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.
I BRAKE I
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.
If the light comes on while you are driving, puli 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, or if the
anti-lock brake system warning light is flashing, have
the vehicle towed for service. (See “Anti-Lock Brake
System Warning Light” and “Towing Your Vehicle”
in
the Index.)

Anti-Lock Brake System Warning Light
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 or if the
anti-lock brake system warning light is flashing
after you’ve pulled off the road and stopped
carefully, have the vehicle towed for service.
With the anti-lock brake
system, this light will
come on when you start
your engine and it will
stay on for three seconds.
That’s normal.
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 flashes when you’re driving, you don’t have
anti-lock brakes and there could be a problem with your
regular brakes. 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.
Have the vehicle towed for service. (See “Towing Your
Vehicle”
in the Index.)
ProCarManuals.com

A CAUTION:
Your regular brake system may not be working
properly if the anti-lock brake system warning light
is flashing. Driving with the anti-lock
brake system warning light flashing can lead to an accident. After you’ve pulled
off the road
and stopped carefully, have the vehicle towed
for service.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition
off. Then start the engine again to reset the
system. If the light still stays on, or comes on again
while you’re driving, your Oldsmobile needs service. If
the light is on but not flashing and the regular brake
system warning light isn’t on, you still have brakes, but
you don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to
RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to warn you if there
is a problem.
Engine Coolant Temperature Gage
’ 260
This gage shows the engine coolant temperature. If the
gage pointer moves into the red area, 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.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.

SERVICE
ENGINE SOON
Your Oldsmobile is
equipped with a computer
which monitors operation
of the
fuel, ignition and
emission control systems.
To prevent damage to your engine, immediate action
is required.
See “Engine Coolant”
in the Index and have your
vehicle serviced
as soon as possible. This
system is called
OBD I1 (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, which may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
ProCarManuals.com

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 malfunction in one
of two ways:
0
0
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. The
following
may prevent more serious damage to
your vehicle:
0 Reduce vehicle speed.
0 Avoid hard accelerations.
0 Avoid steep uphill grades.
0 If 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. Put your vehicle in PARK (P). 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.
ProCarManuals.com

If 3 Light Is On Steady
IOU may be able to correct the emission system
malfunction by considering the following:
Did you just 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. This will
allow fuel to evaporate into the atmosphere.
A few
driving trips 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.
Are you low on fuel?
As your engine starts to run out of fuel, your engine may
not run as efficiently
as designed since small amounts of
air are sucked into the fuel line causing a misfire. The
system can detect this. Adding fuel should correct this
condition. Make sure
to install the fuel cap properly.
It will take
a few driving trips to 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 this condition, 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.

Oil Pressure Indicator
Your vehicle is equipped with an oil pressure indicator.
Your oil pressure indicator lets you know when you may
have
a problem with your engine oil pressure.
When the engine is running, readings
within the white
area indicate the normal operating range. Readings
in or
below the red area indicate that the engine's oil level
may be dangerously low, or there may be another
problem causing low
oil pressure. Driving your vehicle
with low
oil pressure can
cause extensive engine damage. Have your vehicle
serviced immediately.
' A CA"T1ON:
