2-68 Precision Control System (PCS) Warning
Light (Option)
United States Canada
This light should come on briefly as you start your engine.
If the light doesn't come on then, have it serviced so it will
be ready to warn you if there's a problem.
If the PCS warning light comes on, it means there
may be a problem with your Precision Control System.
When this light comes on, so will the TRAC OFF light
and both the Precision Control System and the Traction
Control System will not be functioning. If these lights
come on, try to reset the system (stop; turn off the
engine; then start the engine again). If the PCS and
TRAC OFF lights remain on, it means there is a
problem and you should see your dealer for service.
Reduce your speed and drive accordingly.
Low Traction Active (LOW TRAC) Light
Your LOW TRAC
(Low Traction Active)
light may come on for one
of the following reasons:

The Precision Control System (PCS) (if equipped)
is active and is adjusting brake pressure to help your
vehicle continue to go in the direction in which you
are steering. The PCS activates when the computer
senses that your vehicle is starting to spin, as might
happen if you hit a patch of ice or other slippery
surface on the road, and assists the driver by
selectively applying any one of the vehicle's brakes.
The system is designed to help you in bad weather
or other difficult driving situations by making the
most of whatever road conditions will allow. When
the system is on, you may hear a noise or feel a
vibration in the brake pedal. This is normal.

The optional Traction Control System is active
and is limiting wheel spin. You may feel the system
working, but this is normal. Slippery road conditions
may exist, so adjust your driving accordingly.

2-69
If the LOW TRAC light comes on, slippery road
conditions may exist, so you should consider slowing
down and adjusting your driving accordingly.
Engine Coolant Temperature Gage
You have a gage that
shows the engine coolant
temperature. If the gage
moves into the shaded
area near the hot mark,
your engine is too hot.
That reading means the same thing as the warning light.
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.
Low Coolant Warning Light
If this light comes on,
your system is low on
coolant, and the engine
may overheat.
This light will come on briefly when the ignition is
turned to ON. This is normal.
See ªEngine Coolantº in the Index for more information,
and have your vehicle serviced as soon as possible.

2-70 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 and a chime will sound 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 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.

2-71
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?
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.

2-72
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.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.

2-73 Oil Warning 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.
This indicates that oil is not going through your engine
quickly enough to keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have your vehicle serviced immediately.
The oil light could also come on when the ignition is on
but the engine is not running. This is normal. The light
comes on as a test to show you it's working, but the light
should go out when you turn the ignition to ON. 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.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.

2-74 Service Vehicle Soon Light
This light will come on
briefly when the ignition
is turned to ON to show
that the bulb is working.
This light indicates problems with your vehicle that are
not related to emissions.
These problems may not be obvious and may affect
vehicle performance and durability. Consult your dealer
for necessary repairs to maintain vehicle performance.
Low Oil Level Light
Your engine is equipped
with an oil level monitoring
system. When the ignition
is turned to ON, the LOW
OIL light will briefly
come on.
If the light does not flash, have it fixed so it will be
ready to warn you if there's a problem.
If the light stays on, stop the vehicle on a level surface
and turn the engine off. Check the oil level using the
engine oil dipstick. (See ªEngine Oilº in the Index.)
The oil level monitoring system only checks oil level
during the brief period between key on and engine
crank. 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
an extended period of time, allowing the oil normally
in circulation to drain back into the oil pan.

2-75 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 the
vehicle serviced right away.
If the CHANGE OIL light comes on and stays on after
you start the engine, have the oil changed.
For additional information see ªEngine Oil, When to
Changeº in the Index. To reset the GM Oil Life System,
see ªHow to Reset the Change Oil Lightº in the Index.
Security Light
This light will come on
when you turn the key to
START and will stay on
until the engine starts.
If you're driving and the SECURITY light comes on
and stays on, your Passlock

system is not working
properly. Your vehicle is not protected by Passlock and
you should see your dealer. For more information, see
ªPasslockº in the Index.
Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.

2-76 Low Washer Fluid Light
This light appears when
your vehicle is low on
windshield washer fluid.
This light will come on when your ignition is turned on
to check the bulb. It will go out after a few seconds.
If the light does not come on when you start your
vehicle, the bulb may need to be replaced. See your
dealer to have it fixed right away.
If this light appears while you're driving, your vehicle is
low on washer fluid. Be sure to refill the tank as soon
as possible so that you'll have washer fluid available
when you need it.
Fuel Gage
United States Canada
Your fuel gage tells you about how much fuel you have
left when the ignition is on.
When the indicator nears empty, you still have a little
fuel left, but you should get more soon.

2-77
Here are four things that some owners ask about. All
these things are normal and do not indicate a problem
with the fuel gage:

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

It takes more (or less) fuel to fill up than the gage
reads. For example, the gage reads half full, but it
takes more (or less) than half the fuel tank's capacity
to fill it.

The gage pointer may move while cornering, braking
or speeding up.

The gage may not indicate empty when the ignition
is turned off.Low Fuel Light
United States Canada
If your vehicle is low on fuel, this warning light near the
fuel gage will come on.
It will also come on for a few seconds when you first
turn on the ignition as a check to show you it's working.
If it doesn't come on then, the bulb may need to be
replaced. See your dealer to have it fixed right away.
