2-42 Malfunction Indicator Lamp (Service
Engine Soon Light)
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 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 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
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.

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.
Did you just drive through a deep puddle of water?

yellowblue
2-44
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
ªFilling Your Tankº in the Index. 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
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.
Oil Pressure Light
If you have a problem with
your oil pressure this light
may stay on after you start
your engine, or come on
when you are driving.
This indicates that there is not enough pressure to keep
your engine properly lubricated and cool. The engine
could be low on oil, or have some other oil problem.
Have it fixed right away.

yellowblue
2-45
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. 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.

Sometimes when the engine is idling at a stop, the
light may blink on and off. This is normal.

If you make a hard stop, the light may come on for a
moment. This is normal.
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.
Daytime Running Lamps (DRL)
Indicator Light
You will have this light on
the instrument panel. It goes
on whenever the daytime
running lamps are on.

3-3 Air Conditioner Controls (If Equipped)
The air conditioning system
uses the same controls as
described previously. The
function of each lever is
explained under ªClimate
Control Systemº in this
part. The incoming air is
cooled and dehumidified
instead of being heated.
Push the A/C button to change your comfort control
system from heating to air conditioning. A light will
come on when the air conditioning is on. The A/C
button can also control the humidity in your vehicle.
The air conditioner works best if you keep your
windows closed. On very hot days, open the windows
just long enough for the hot air to escape.For normal cooling, push the A/C button and move the
air intake lever to CIRCULATE. For faster cooling,
move the lever to RECIRCULATE. Then move the
airflow lever to VENT, the temperature control lever
toward the left and the fan control lever toward the
fan symbol.
On days when it is raining or the humidity is high,
follow these dehumidifying steps to help clean windows
that are cloudy with moisture. Push the A/C button.
Move the air intake lever to CIRCULATE. Move the
airflow lever to DEFROST and the fan control lever
toward the fan symbol. Adjust the temperature control
lever to a comfortable setting.
Heating
For the quickest results, move the air intake lever to
RECIRCULATE. Move the airflow lever to FLOOR, the
temperature control lever toward the right for warmer
air and the fan control lever toward the fan symbol. You
should switch to CIRCULATE once in a while to avoid
stale air and cloudy windows.

Playing a Compact Disc
With the radio on, insert a disc into the CD slot, label
side up. The player will pull it in. The disc should begin
playing. A CD symbol is shown in the center of the
graphic display whenever a disc is inserted.
Don't use the smaller discs (three
-inch singles). They
won't eject. Use full
-size compact discs.If you're driving on a very rough road or if it's very hot,
the disc may not play and Err (error) may appear on the
display. Press RECALL to take Err off the display.
When things get back to normal, the disc should play. If
the disc comes out, it could be that:

The disc is upside down. The player will not pull the
disc in.

It is dirty, scratched or wet.

It is very humid. (If so, wait about an hour and
try again.)
While the CD is playing, use the VOLUME, FADE,
BAL, TREB, BASS and TONE controls just as you do
for the radio. The CD player automatically begins
playing again when it reaches the end of the disc.
A disc that has been ejected but is still sitting in the
remote CD player will be pulled back into the player
after approximately 30 seconds. This protects the disc
and player from damage. The disc will not start playing.
To remove the disc, press the EJECT button and remove
the disc from the player.
REV (TUNE): Press and hold the left arrows to reverse
rapidly within a track. Release it to resume playing.

3-16 Care of Your Cassette Tape Player
A tape player that is not cleaned regularly can cause
reduced sound quality, ruined cassettes or a damaged
mechanism. Cassette tapes should be stored in their
cases away from contaminants, direct sunlight and
extreme heat. If they aren't, they may not operate
properly or may cause failure of the tape player.
Your tape player should be cleaned regularly after every
50 hours of use. Your radio may display CLEAN to
indicate that you have used your tape player for 50
hours without resetting the tape clean timer. If this
message appears on the display, your cassette tape
player needs to be cleaned. It will still play tapes, but
you should clean it as soon as possible to prevent
damage to your tapes and player. If you notice a
reduction in sound quality, try a known good cassette to
see if it is the tape or the tape player at fault. If this other
cassette has no improvement in sound quality, clean the
tape player.
The recommended cleaning method for your cassette
tape player is the use of a scrubbing action,
non
-abrasive cleaning cassette with pads which scrub
the tape head as the hubs of the cleaner cassette turn.
The recommended cleaning cassette is available through
your dealership (GM Part No. 12344789).When using a scrubbing action, non
-abrasive cleaning
cassette, it is normal for the cassette to eject because
your unit is equipped with a cut tape detection feature
and a cleaning cassette may appear as a broken tape. To
prevent the cleaning cassette from being ejected, use the
following steps.
1. Turn the ignition to ON or ACC.
2. Turn the radio off.
3. Press and hold the TAPE button for five seconds.
The tape symbol on the display will flash for
two seconds.
4. Insert the scrubbing action cleaning cassette.
5. Eject the cleaning cassette after the manufacturer's
recommended cleaning time.
When the cleaning cassette has been ejected, the cut tape
detection feature is active again.
You may also choose a non
-scrubbing action, wet-type
cleaner which uses a cassette with a fabric belt to clean
the tape head. This type of cleaning cassette will not
eject on its own. A non
-scrubbing action cleaner may
not clean as thoroughly as the scrubbing type cleaner.
The use of a non
-scrubbing action, dry-type cleaning
cassette is not recommended.
