If the TC (traction control) warning light stays on or
comes on while you are driving, pull off the road as
soon as possible and stop carefully. Try resetting
the system by turning the ignition off then back on. If
the light still stays on or comes back on again while you
are driving, your vehicle needs service. Have the
traction control system inspected as soon as possible.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the gage pointer is near 260 ÉF (125 ÉC), the engine
is too hot.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
Engine Overheating on page 5-28for more
information.
Malfunction Indicator Lamp
Check Engine 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 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 awhile, 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:Modi®cations made to the engine,
transmission, 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.
Modi®cations 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
Ð A mis®re condition has been
detected. A mis®re increases vehicle emissions
and may damage the emission control system on
your vehicle. Diagnosis and service may be
required.
·Light On Steady Ð An emission control system
malfunction has been detected on your vehicle.
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 ¯ashing and remains on steady,
see ªIf the Light Is On Steadyº following.
If the light continues to ¯ash, 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 ¯ashing, follow the
previous steps, and see your dealer for service as soon
as possible.
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
Filling Your Tank on page 5-8. 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.

Oil Pressure Gage
The oil pressure gage shows the engine oil pressure
in psi (pounds per square inch) when the engine
is running. Canadian vehicles indicate pressure in
kPa (kilopascals).
{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.
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused
by a low oil level or other oil-related problems. See your
dealer for service immediately.

Reduced Engine Power Light
This light is displayed
when a noticeable
reduction in the vehicle's
performance may occur.
The vehicle may be driven at a reduced speed when
the reduced engine power light is on but acceleration
and speed may be reduced. The performance may
be reduced until the next time you drive your vehicle.
If this light stays on, see your dealer as soon as possible
for diagnosis and repair.
This light may also come on if there is a problem with
the Throttle Actuator Control (TAC) system. If this
happens, take the vehicle in for service as soon as
possible.
Highbeam On Light
This light comes on
whenever the high-beam
headlamps are on.
Check Gages Warning Light
The Check Gages light will
come on brie¯y when you
are starting the engine.
If the light comes on and stays on while you are
driving, check your coolant temperature and engine oil
pressure gages to see if they are in the warning
zones. See
Engine Coolant Temperature Gage on
page 3-32andOil Pressure Gage on page 3-36.
3-38
Page 159 of 388
You can only drive for a short time with the reading in
either warning zone. If you must drive while the gage is
in the warning zone, turn off all unnecessary
accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Delivered Torque Gage
This gage (B) is located in
the center of the gage
package.
This gage displays the delivered torque for the vehicle.
Outside Temperature Gage
This gage (C) is located on
the right side of the gage
package.
This gage displays the outside temperature.

Engine Coolant Hot Idle Engine
Notice:If your engine catches ®re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
If the cooling system temperature becomes too hot,
this message will appear in the DIC and you will hear
a chime. Stop the vehicle and let the engine idle in
PARK (P) to allow the coolant to reach a safe
temperature. You may need to add more coolant to your
vehicle before driving again. See
Engine Coolant on
page 5-26andEngine Coolant Temperature Gage
on page 3-32for more information. This message will
clear from the DIC display when the coolant temperature
drops to a safe operating temperature.
Engine Overheated Stop Engine
Notice:If your engine catches ®re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
If your engine is overheated, this message will be
displayed on the DIC. Stop the vehicle as soon as
possible and do not drive it until the engine cools down. You may need to add more coolant to your vehicle
before driving again. See
Engine Overheating on
page 5-28andEngine Coolant Temperature Gage on
page 3-32for more information. This message will clear
from the DIC display when the coolant temperature
drops to a safe operating temperature.
Flip Hall Switch Fault
This message will be displayed on the DIC when trying
to raise or lower the convertible top and there is a
fault with this switch. If the message persists, see your
GM dealer for service.
Fuel Level Low
If the fuel level is low in the vehicle's gas tank, this
message will appear on the DIC and you will hear a
chime. You will also see the check gages warning light
on the instrument panel cluster. See
Check Gages
Warning Light on page 3-38for more information. Refuel
as soon as possible. SeeFilling Your Tank on page 5-8andFuel Gage on page 3-39for more information.
