2001 Oldsmobile Alero Owner's Manuals

2-67
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. Dealer or qualified service center diagnosis
and service may be required.

Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer 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
ªIf the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer 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. See ªFilling Your Tankº in the Index. 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.

2-68
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
ªFuelº 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 dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic tools to fix any mechanical or electrical
problems that may have developed.Emissions Inspection and Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a
vehicle registration.
Here are some things you need to know in order to help
your vehicle pass an inspection:
Your vehicle will not pass this inspection if the
SERVICE ENGINE SOON or CHECK ENGINE light is
on or not working properly.
Your vehicle will not pass this inspection if the
OBD (on
-board diagnostic) system determines that
critical emission control systems have not been
completely diagnosed by the system. The vehicle would
be considered not ready for inspection. This can happen
if you have recently replaced your battery or if your
battery has run down. The diagnostic system is designed
to evaluate critical emission control systems during
normal driving. This may take several days of routine
driving. If you have done this and your vehicle still does
not pass the inspection for lack of OBD system
readiness, see your dealer or qualified service center to
prepare the vehicle for inspection.

2-69 Oil Pressure 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 bulb. Have it fixed right away.CAUTION:
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 your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

2-70 Low Oil Light (If Equipped)
If your vehicle is equipped
with a 3400 V6 engine, then
you will have a LOW OIL
light in your instrument
panel cluster.
This light will come on briefly when you start your vehicle.
If the light stays on after starting your vehicle, or comes
on and chimes while you are driving, your engine oil
level should be checked.
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 ªEngine Oilº in the Index.
A false LOW OIL light may be generated when parking
on steep grades.
The oil level monitoring system only checks oil level
during the brief period between when the key is on and
the engine is cranking. 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.
Change Oil Light
The CHANGE OIL light
should come on briefly as a
bulb check when you start
the engine. If the light
doesn't come on, have
it serviced.
If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
To reset the CHANGE OIL light, see ªEngine Oil,
When to Changeº in the Index.

2-71 Security Light
This light will come on
when you turn the key to
ON and will stay on until
the vehicle starts.
If you're driving and the security light comes on and
remains on, your Passlock

system is not working
properly. Your vehicle is not protected by Passlock and
you should see your dealer.
Cruise Light
The CRUISE light comes
on whenever you set your
cruise control.
Low Washer Light
United States Canada
This light will come on briefly when you turn on the
ignition. It will also stay on, or come on and a chime
will sound, if the windshield washer fluid reservoir is
less than one
-third full.

2-72 Service Vehicle Soon Light
This light will come on
briefly when you turn on
the ignition.
It will stay on, or come on and a chime will sound if it detects
a problem on the vehicle, such as a Daytime Running Lamps
(DRL) or an Automatic Light Control (ALC) malfunction.
If this happens, see your dealer as soon as possible.
Fuel Gage
United States CanadaYour fuel gage tells you about how much fuel you have left,
when the ignition is on. When the indicator nears empty, the
light will come on and you will hear a chime. You still have a
little fuel left, but you should get more soon.
Here are four things that some owners ask about. None
of these show a problem with your fuel gage:

At the service station, the gas pump shuts off before
the gage reads full.

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 indicator moves a little when you turn a corner
or speed up.

The gage goes back to empty when you turn off
the ignition.
