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 see your dealer for service as soon
as possible.
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. SeeFilling the 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.
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
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can 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.
3-36

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, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
If you have low engine oil
pressure, this light will stay
on after you start your
engine, or come on 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 by
your GM dealer.The oil light could also come on in three other situations:
•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. The light will go out when you turn
the ignition on. If it does not come on with the
ignition on, you may have a problem with the fuse
or bulb. Have it fixed right away.
•If you are idling at a stop sign, the light may blink
on and then off.
•If you make a hard stop, the light may come on for
a moment. This is normal.
{CAUTION:
Do not keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be covered
by your warranty. Always follow the maintenance
schedule in this manual for changing engine oil.

Playing a CD
Insert a CD partway into the slot, label side up. The
player will pull it in and the CD should begin playing.
You can insert a CD with the ignition off.
When the CD is inserted, CDP will appear on the
display. As the CD is loading Filecheck will appear on
the display. As each new track starts to play, Track and
the track number will appear on the display.If the ignition or radio is turned off with a CD in the
player, it will stay in the player. When a CD is in
the player and the ignition is turned on, the radio must
be turned on before the CD will start playback. When
the ignition and radio are turned on, the CD will
start playing where it stopped, if it was the last selected
audio source.
The CD player can play the smaller 3 inch (8 cm) single
CDs with an adapter ring. Full-size CDs and the
smaller CDs are loaded in the same manner.
If playing a CD-R, the sound quality may be reduced
due to CD-R quality, the method of recording, the quality
of the music that has been recorded, and the way the
CD-R has been handled. There may be an increase
in skipping, difficulty in finding tracks, and/or difficulty in
loading and ejecting. If these problems occur, check
the bottom surface of the CD. If the surface of the CD is
damaged, such as cracked, broken, or scratched, the
CD will not play properly. If the surface of the CD
is soiled, seeCare of Your CDs on page 3-71for more
information.
If there is no apparent damage, try a known good CD.

Do not add any label to a CD, it could get caught in the
CD player. If a CD is recorded on a personal computer
and a description label is needed, try labeling the top of
the recorded CD with a marking pen instead.
Notice:If you add any label to a CD, insert more
than one CD into the slot at a time, or attempt
to play scratched or damaged CDs, you could
damage the CD player. When using the CD player,
use only CDs in good condition without any
label, load one CD at a time, and keep the CD player
and the loading slot free of foreign materials,
liquids, and debris.
