Your vehicle is equipped with a computer which
monitors operation
of the fuel, ignition and emission
control systems.

ProCarManuals.com
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
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 this 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. 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.
b 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 restad 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 dealer
or qualified service center for service.
If the Light Is on Steady
You also 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
Filhg Your Tank on page 5-7. 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.
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. See
Filling Your Tank on page 5-7. 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
Gasoline Octane on page 5-5. 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
UI-I~ iuii ia~k ui iile pruper iuei iu iurrl iile iiyili uii.
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 to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection
if the 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.
Oil Pressure Light
If you have a problem with
your
oil, this light may stay
on after you start your
engine, or come on when
you are driving.
A warning chime and the DIC message
LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be
low on oil, or could have some other oil problem. Have
it fixed right away.
The oil light could also come on briefly 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 about five seconds after you turn
the ignition to START.
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.

Oil Life
The GM Oil Life SystemTM is the only function accessible
in the OIL mode. Engine oil life is displayed in a
reading such as the following:
OIL LIFE 30%
This is an estimate of the oil’s remaining useful life. It
will show
100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining
oil life is low, the system will alert
you with this message:
CHANGE OIL
SOON
Always reset the OIL LIFE reminder after an oil change.
To reset the oil life system, see “How to Reset the
Oil Life System” under
Engine Oil on page 5-75.
Remember, you must reset the OIL LIFE yourself after
each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed. It
can’t be reset accurately until the next oil change.
The DIC does not replace the need to maintain your
vehicle as recommended in the Maintenance Schedule
in this manual.
Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil. If you drive
in dusty areas, change your
oil after every
3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you
to do
so sooner. Also, the oil change reminder does not
measure how much oil you have in your engine.
So,
be sure to check your oil level often. See Engine Oil on
page 5- 15.
