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. United States

Change Engine Oil Light
This light is displayed
when the engine oil needs
to be changed.
Once the engine oil has been changed, the light must
be reset. Until it is reset, the light will be displayed when
the engine is on. For more information on resetting
the system, see “When to Change Engine Oil (GM Oil
Life System)” underEngine Oil on page 5-14.
Security Light

on page 2-14.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
®
system. Your vehicle will not be protected by Passlock®,
and you should see your dealer.
Also, seeContent Theft-Deterrent on page 2-12for
additional information regarding the security light.

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.
SeeEngine Coolant Temperature Gage on page 3-30
andOil Pressure Gage on page 3-34.
When the fuel level is low in your vehicle, the check
gages light will come on and a chime will sound. You will
also see a FUEL LEVEL LOW message on the DIC.
SeeDIC Warnings and Messages on page 3-45
for more information.

Auxiliary Gage Package
A. Voltmeter Gage
B. Instantaneous Fuel Consumption Gage
C. Transmission Temperature Gage
Your vehicle may have an auxiliary gage package
located at the front of the center console.
Voltmeter Gage
This gage (A) is located on
the left side of the gage
package.
When your engine is not running, but the ignition is in
RUN, this gage shows your battery’s state of charge in
DC volts.
When the ignition is on and the engine is running, the
gage shows the condition of the charging system.
Readings between the low and high warning zones
indicate the normal operating range.
3-38
Page 143 of 374
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left at an idle for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
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.Instantaneous Fuel Consumption Gage
This gage (B) is located in
the center of the gage
package.
The instantaneous fuel consumption gage shows the
rate of fuel that is being used in gallons per hour (gph).
