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 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.

2-76 Oil Pressure 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.
A warning chime and the DIC message LOW OIL
PRESSURE may also come on.
These indicate that oil is not going through your engine
quickly enough to keep it cool. The engine could be low
on oil, or could have some other oil problem. Have it
fixed right away.
The oil light could also come on briefly 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, but
the light will go out about five seconds after you turn
the ignition to START. 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.

2-77 Cruise Light
The CRUISE light comes
on whenever you set your
cruise control. See ªCruise
Controlº in the Index.
This light will come on for a few seconds when you turn
the ignition key to RUN to let you know it is working.
Fuel Gage
United States CanadaWhen the ignition is on, your fuel gage tells you about
how much fuel you have left.
When you have less than 3.0 gallons (11.3 L) of
fuel remaining, the DIC message LOW FUEL will
be displayed and a chime will sound. You need to get
more fuel right away.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the service station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to fill up than the
gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took
a little more or less than half the tank's capacity to
fill the tank.
The gage moves a little when you turn a corner
or speed up.
The tank is not necessarily empty when the gage
reads empty. There is a reserve of about 1.5 gallons
(5.6 L) in the tank. You should still get more fuel
as soon as possible.

The DIC will then ask for the day. The day will flash the
same as the year. Use the SELECT buttons to reach the
current day. Press the RESET button again and the set
display will stop flashing and go back to the normal
operation mode.Elapsed Time (ET)
When the ignition is on, the DIC can be used as a
stopwatch. The display will show hours and minutes.
The elapsed time indicator will record up to 100 hours,
then it will reset to zero and continue counting. Press
SELECT down arrow while in the DATE/ET mode,
and the display will show the amount of time that has
elapsed since the elapsed time indicator was last reset
(not including time the ignition is off), such as:
01:08 ELAPSED TIME
To start or stop the counting of time, press the RESET
button briefly. If the colon (:) in the time is flashing,
time is being counted. Time is displayed in hours and
minutes. Seconds are not displayed. Time will continue
to be counted as long as the ignition is on, even if
another display is being shown on the DIC.
To reset elapsed time to zero, press RESET button
for three seconds while the elapsed time is displayed.

2-80 Fuel
Press SELECT down arrow while in the FUEL mode
to see how much fuel has been used and the fuel
range functions.
Fuel Used
While in the FUEL USED function the display will
show a reading such as:
FUEL USED: 10.4 GAL or FUEL USED: 39.4 L
To learn how much fuel will be used from a specific
starting point, first enter the FUEL USED mode to
display FUEL USED, then press and hold the
RESET button for three seconds.
Don't confuse fuel used with the amount of fuel in
your tank.
Fuel Range
The FUEL RANGE mode calculates the remaining
distance you can drive without refueling. It's based
on fuel economy and the fuel remaining in the tank.
The display will show a reading such as:
FUEL RANGE: 235 MI or FUEL RANGE: 378 KMIf the range is less than 50 miles (80 km), the display
will read LOW FUEL RANGE.
The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your driving
conditions change, this data is gradually updated.
Fuel range cannot be reset.
Fuel Economy
Pressing the SELECT down arrow while in the ECON
mode displays average fuel economy and instantaneous fuel
economy calculated for your specific driving conditions.
Average fuel economy will be shown in a reading such as:
25.2 AVG MI/GAL or 9.3 AVG L/100 KM
Instantaneous fuel economy will be shown in a reading
such as:
28 INST MI/GAL or 8.4 INST L/100 KM
The average fuel economy is viewed as a long
-term
approximation of your overall driving conditions.
If you press and hold RESET for three seconds in
this mode while you're driving, the system will begin
figuring average fuel economy from that point in time.
Instantaneous fuel economy cannot be reset.

2-81 Oil Life
The GM Oil Life System is the only function
accessible in the OIL mode. Engine oil life is displayed
in a reading such as:
OIL LIFE 30%
This is an estimate of the oil's remaining useful life.
It will show 100% when the system is reset after an
oil change. It will alert you to change your oil on a
schedule consistent with your driving conditions.
When the remaining oil life is low, the system will
alert you with this message:
CHANGE OIL SOON
When the oil life is down to zero, you will receive
this message:
CHANGE OIL NOW
Always reset the OIL LIFE reminder after an oil change.
To reset the Oil Life System, see ªOil Life Systemº in
the Index. Also, see ªEngine Oil, When to Changeº in
the Index.Remember, you must reset the OIL LIFE yourself
after each oil change. It will not reset itself. Also, be
careful not to reset the OIL LIFE accidentally at any
time other than when the oil has just been changed.
It can't be reset accurately until the next oil change.
The DIC does not replace the need to maintain your
vehicle as recommended in the Maintenance Schedule
in this manual. Also, the oil change reminder will not
detect dusty conditions or engine malfunctions that may
affect the oil. If you drive in dusty areas, change your
oil after every 3,000 miles (5 000 km) or three months,
whichever occurs first, unless the DIC instructs you to
do so sooner. Also, the oil change reminder does not
measure how much oil you have in your engine. So,
be sure to check your oil level often. See ªEngine Oilº
in the Index.

2-82 Gage
Pressing the SELECT down arrow while in GAGE
mode will allow you to access the battery volts, oil
pressure and tire pressure displays. Pressing and holding
the RESET button for three seconds while in average
speed and tire pressure displays will reset them. Pressing
the SELECT down arrow in GAGE mode will show
the following displays:
Battery voltage, such as:
VOLTS: 13.8
Oil pressure, such as:

Average speed, such as:
AVG SPEED 55 MPH or AVG SPEED
90 KM/HTire pressure status, such as:
TIRE PRESSURE NORMAL or LOW
TIRE PRESSURE
TIRE PRESSURE NORMAL appears when the
Check Tire Pressure System believes your vehicle's
tire pressures are normal. If a potential tire pressure
problem is detected, the display will show LOW
TIRE PRESSURE. If you see this message, you
should stop as you can and check all four tires for
damage. If a tire is flat, see ªIf a Tire Goes Flat º
in the Index. Also check the tire pressure in all four
tires as soon as you can. See ªTire Pressureº in
the Index.
There are times when you will have to reset
(calibrate) the Check Tire Pressure System.
See ªCheck Tire Pressure Systemº in the Index
for more information.
