Tire Pressure Light
The check tire pressure system can alert you to a large
change in the pressure of one tire.
After the system has been
properly calibrated, the
TIRE PRESS light
will come on if a pressure
difference (low pressure)
is detected in one tire.
The light will stay on until you turn off the ignition or
reset (calibrate) the system. SeeCheck Tire Pressure
System on page 5-68.
The TIRE PRESS light also comes on briey when you
turn your ignition key to START. If the light doesn’t
come on then, have it xed so it will be there to tell you
if the pressure in a tire is low.
If the anti-lock brake system warning light comes on,
the check tire pressure system may not be working
properly. See your dealer for service. Also, see
Anti-Lock Brake System Warning Light on page 3-44.On vehicles with the optional Driver Information Center
(DIC), a CHECK TIRE PRESSURE message replaces
the TIRE PRESS light when the system detects a
pressure difference (low pressure) in one tire. SeeDIC
Warnings and Messages on page 3-61for more
information.
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.
3-48

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:Modications 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.
Modications 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 does not come on, have it
repaired. This light will also come on during a
malfunction in one of two ways:
Light Flashing— A misre condition has been
detected. A misre increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
Light On Steady— An emission control system
malfunction has been detected on your vehicle.
Diagnosis and service may be required.
3-49

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 x 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 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, your GM dealer can prepare the
vehicle for inspection.

Oil Pressure Gage
Readings above the shaded warning zone indicate the
normal operating range. Oil pressure may vary with
engine speed, outside temperature and oil viscosity.
A reading in the shaded warning zone may be caused
by a low oil level or another problem causing low oil
pressure. On vehicles with the systems monitor,
the CHECK GAGES light will come on and a warning
chime will sound.On vehicles with a DIC, a CHECK GAGES OIL
PRESSURE message will be displayed and a warning
chime will sound. SeeDIC Warnings and Messages
on page 3-61for more information.
{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. United States

SERVICE STABILITY SYSTEM – 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system: stop, turn off the engine, then start the
engine again. If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you are
steering. This stability enhancement system activates
when the computer senses that your vehicle is just
starting to spin, as it might if you hit a patch of ice or other
slippery spot on the road. When the system is on, you
may hear a noise or feel a vibration in the brake pedal.
This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want to
go. The system is designed to help you in bad weather or
other difficult driving situations by making the most of
whatever road conditions will permit. If the STABILITY
SYSTEM ACTIVE message comes on, you will know that
something has caused your vehicle to start to spin, so
you should consider slowing down.Tire Pressure Status – 144:If you see the CHECK
TIRE PRESSURE message, you should stop as soon as
you can and check all your tires for damage. If a tire
is at, seeIf a Tire Goes Flat on page 5-79. Also check
the tire pressure in all four tires as soon as you can.
