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.
BRAKE
This light should come on
briefly when you turn the
ignition key to
ON. 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 and chime come 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.)
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.

Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will
come on when you turn
your ignition on or start your engine and it
will
stay on for three seconds.
That’s normal.
If the light stays on and the chime sounds, turn the
ignition to
OFF. Or, if the light comes 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 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.

Low Coolant Warning Light
m J
This light comes on briefly when you turn your ignition on.
Malfunction Indicator Lamp (Check Engine Light)
CHECK
Your Oldsmobile is
equipped with a computer
which monitors operation of the fuel, ignition and
emission control systems.
If this light comes on and stays on and you hear a chime,
the vehicle should promptly be pulled
off the road and
the coolant level checked.
See “Engine Coolant” in the Index.
If there are visible
signs
of steam, see “Engine Overheating” in the Index
before opening the hood. Have your vehicle serviced as
soon as you can. 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
CHECK ENGINE 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.

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:
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:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
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.

Oil Pressure Warning Light
If you have a low engine oil
pressure problem, this light will stay on after you start
your engine, or come on
and you
will hear a chime
when you
are driving.
This indicates that your engine is not receiving enough
oil. The engine could be low on oil, or could have some
other oil problem. Have
it fixed immediately.
When the ignition is on 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 the engine is
running.
If it doesn't come on with the ignition on,
you may have a problem with the fuse or bulb. Have
it fixed right away. 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 vow
vehicle serviced.

I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

Check Oil Light Passlock Warning Light
CHECK
OIL
If the light
comes on and
you hear a chime or stays on after starting your vehicle,
your engine oil level should
be checked.
THEFT
SYSTEM
This light will come on
briefly when
you turn
the ignition on. The light
will stay on until the
engine
starts.
Prior to checking the oil level, be sure your vehicle has
been shut
off for several minutes and is on a level
surface. Check the oil level on your dipstick and bring
it to the proper level. See “Engine Oil” in the Index.
NOTE:
A false CHECK OIL light may be generated
when parking on steep grades.
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank.
It does not monitor engine oil level when the
engine is running. Additionally, an oil level check is
only performed if the engine has been turned
off for a
considerable period
of time allowing the oil normally in
circulation
to drain back into the oil pan.
If the light flashes for several seconds, the Passlock
system has entered a tamper mode.
If the vehicle fails
to start, see “Passlock” in the Index.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
system.
Your vehicle will not be protected by Passlock,
and you should see your retailer.
