2001 Oldsmobile Alero ignition

2-65 Low Tire Pressure Light (If Equipped)
The tire pressure
monitor system can
alert you to a large
change in the
pressure in one tire.
After the system has ªlearnedº tire pressures with
properly inflated tires, the LOW TIRE PRESSURE light
will come on if the pressure in one tire becomes 12 psi
(83 kPa) lower than the other three tires. The tire
pressure monitor system won't alert you if the pressure
in more than one tire is low, if the system is not yet
calibrated, or if the vehicle is moving at less than
15 mph (25 km/h), faster than 75 mph (120 km/h), on
rough roads or during turns. The light may also come on
if you are driving on partially cleared pavement.When the LOW TIRE PRESSURE light comes on, you
should stop as soon as you can and check all your tires
for damage. (If a tire is flat, see ªIf a Tire Goes Flatº in
the Index.) Also check the tire pressure in all four tires
as soon as you can. See ªInflation
- Tire Pressureº in
the Index.
The light will stay on (while the ignition is on) until you
reset (calibrate) the system. See ªTire Pressure Monitor
Systemº in the Index.
The LOW TIRE PRESSURE light also comes on briefly
when you turn the ignition key to ON. If the light
doesn't come on then, have it fixed so it will be there to
tell you if the pressure in a tire is low or high.
If the anti
-lock brake system warning light comes on,
the tire pressure monitor system may not be working.
See your dealer for service. Also, see ªAnti
-Lock Brake
System Warning Lightº in the Index.

2-66 Malfunction Indicator Lamp
(Service Engine Soon Light in the United
States or Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.
This system is called OBD II (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 or 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.
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance
Criteria (TPC) can affect your vehicle's emission
controls and may cause the SERVICE ENGINE
SOON or the CHECK ENGINE light to come on.
Modifications to these systems could lead to
costly repairs not covered by your warranty.
This may also result in a failure to pass a
required Emission Inspection/Maintenance test.

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.

2-69 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.

2-71 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.

3-5 Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the defogger button. The indicator light will glow.
The rear window defogger will turn itself off after about
10 minutes after the first time the button is pressed,
and after five minutes each additional time the button
is pressed. You can turn the defogger off by pressing
the button again or turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.NOTICE:
Don't use a razor blade or anything else sharp
on the inside of the rear window. If you do, you
could cut or damage the warming grid, and the
repairs wouldn't be covered by your warranty.
Ventilation System
For mild outside temperatures when little heating or
cooling is needed, use UPPER to direct outside air
through your vehicle. Your vehicle also has the
flow
-through ventilation system.
Your vehicle's flow
-through ventilation system supplies
outside air into the vehicle when it is moving. Outside
air will also enter the vehicle when the air conditioning
fan is running.
