Fuel Information Button
Use the fuel information button to scroll through the
range, average fuel economy, instant fuel economy and
the GM
Oil Life SystemTM.
If your vehicle is not equipped with the DIC steering
wheel control buttons you will not be able to display the
fuel information.
Fuel Range
Press the fuel information button until RANGE appears
to display 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
LOW if
the fuel level is low.
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.
Average Fuel Economy
Press the fuel information button until AVG appears in
the display. Average fuel economy is how many
miles per gallon your vehicle is getting based on current
and past driving conditions.
Press and hold the select button while AVG.ECON is
displayed to reset the average fuel economy. Average
fuel economy will then
be calculated starting from
that point.
If the average fuel economy is not reset, it
will be continually updated each time you drive.
Instant Fuel Economy
Press the fuel information button until INST appears in
the display. Instant fuel economy is how many miles
per gallon your vehicle is at the particular moment
in time. The instant fuel economy cannot be reset.
GM Oil Life SystemTM
Press the fuel information button until ENGINE OIL LIFE
appears in the display. The GM
Oil Life SystemTM
shows 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.
Always reset the engine oil life after and oil change.
To
reset the Oil Life System press and hold the select
button while ENGINE
OIL LIFE is displayed.
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. 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
Engine Oil on
page 5- 13.

Footnotes
t The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle
's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection on page
6-15.
Engine Oil and Chassis Lubrication
Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life SystemTM (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change
is
necessary. A CHANGE ENGINE OIL message will
come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
it
you are driving under the best conditions, the oil life
system may not indicate that an
oil change is necessary
for over a year. However, your engine
oil and filter
must be changed at least once a year and at this time
the system must be reset. It
is also important to
check your oil regularly and keep
it at the proper level.
6-5

If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page 5-73
for information on resetting the system.
An Emission Control Service.
Lubricate chassis components with each engine oil
and filter change.
Lubricate the front suspension, ball joints, steering
linkage, transmission shift linkage, transfer case shift
linkage and parking brake cable guides. Ball joints
should not be lubricated unless their temperature is
10°F (-12°C) or higher or they could be damaged.
After the services are performed, record the date,
odometer reading and who performed the service on the
maintenance record pages in Part
E of this schedule.
