instrument panel cluster below the speedometer and
tachometer, directly above the steering column.
The following buttons are located on the DIC control panel
which is located to the right of the instrument panel cluster.
1 FUEL: Press this button to display fuel information
such as fuel economy and range.
2 GAGES: Use this button to display gage information
like oil pressure and temperature, coolant temperature,
automatic transmission fluid temperature, battery
voltage and front/rear tire pressures.
3 TRIP: Use this button to display your total and trip
miles, the elapsed time function, your average speed and
the engine oil life.
4 OPTIONS: This button allows you to choose personal
options that are available on your vehicle, depending on
the options your vehicle is equipped with, such as
security, door locks, easy entry seats and language.
5 E/M: Use this button to change the display between
English and metric units.

Press FUEL again to display instantaneous fuel
economy, such as:

INST. 20.1 MPG or

INST. 5.3 L/100 km
Press FUEL again to display the range, such as:

RANGE 20 MI or

RANGE 32 km
The range calculates the remaining distance you can
drive without refueling. It's based on fuel economy and
the fuel remaining in the tank.
If the range is lower than 30 miles (48 km), the display
will read RANGE 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. Resetting
the fuel range causes the fuel economy data to be updated
immediately. Press RESET to reset the fuel range.2 GAGES
The GAGES button allows you to scroll through the
functions listed below when you press it.
Press the GAGE button to display the oil pressure,
such as:

OIL PRESSURE 40 PSI or

OIL PRESSURE 276 kPa

Miles Since Last Ignition Feature
You can also display number of miles (kilometers)
driven since you last started the vehicle if you press and
hold the RESET button for two seconds, then release.
The miles (or kilometers) since the last ignition cycle
will be set into the trip odometer.
Elapsed Time
Press the TRIP button until ELAP. TIME is displayed,
such as ELAP. TIME 00:00:00.00.
When the ignition is in ON, the Driver Information
Center (DIC) can be used as a stopwatch. The display
can show hours, minutes, seconds and hundredths of
a second. The elapsed time indicator will record up to
99 hours, 59 minutes and 59 seconds, then it will reset
to zero and continue counting. (Hundredths are shown
up to 59 minutes, 59 seconds and 99 hundredths). The
display appears as ELAP. TIME 00:00:00.00 in the
elapsed time function.
You can start or stop the elapsed time by pressing
RESET. To reset the elapsed time to zero, stop the timer
by pressing RESET. Then press and hold RESET until
ELAP. TIME 00:00:00.00 appears in the DIC.Average Speed
Press the TRIP button until the average speed is
displayed, such as:

AVERAGE SPEED 62 MPH or

AVERAGE SPEED 100 km/h
Press reset in this mode to start calculating the average
speed. Press and hold RESET to clear.
Engine Oil Life
Press the TRIP button until the engine oil life is
displayed, such as OIL LIFE REMAIN 89%.
This is an estimate of the engine oil's remaining useful
life. It will show 99% 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 the message CHANGE OIL SOON.
When the oil life is down to zero, you will receive the
message CHANGE OIL NOW.

2-99
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.
To reset the system, see ªHow to Reset the Change Oil
Soon Messageº in the Index.

button, a message will be displayed and you will hear a
chime every minute until the vehicle is serviced. If you

Low oil pressure may be the result of a combination of
low oil level and abrupt changes in the vehicle's
direction. When this warning is displayed, you should
not operate the engine at high rpm or make fast abrupt
moves. As soon as possible, you should check the oil
level. See ªEngine Oilº in the Index.
LOW OIL LEVEL: Press RESET to acknowledge that
you have read the message and to remove it from the
display. The message will reappear every 10 minutes
until this condition changes.
You will hear two chimes when this message is
displayed. If this message appears after starting your

acknowledge that you have read the message and to
remove it from the display, press RESET.
The message will reappear every 15 seconds until this
condition changes.
If the Driver Information Center (DIC) displays the
REDUCED ENGINE POWER message and the
CHECK ENGINE light comes on, a noticeable
reduction in the vehicle's performance may occur. If the
REDUCED ENGINE POWER message is displayed but
there is no reduction in performance, proceed to your
destination. The performance may be reduced the next
time the vehicle is driven.
The vehicle may be driven at a reduced speed while the
REDUCED ENGINE POWER message is displayed,
but acceleration and speed may be reduced. Anytime the
CHECK ENGINE light stays on, the vehicle should be
taken to an authorized Chevrolet dealer as soon as
possible for diagnosis and repair.
Also, refer to ªMalfunction Indicator Lampº
(Check Engine Light) in the Index. If the REDUCED
ENGINE POWER message is displayed in combination
with the COOLANT OVER TEMP message, see
ªEngine Overheatingº in the Index.

will hear a chime every minute until this condition
changes. If you do not press RESET, the message will
remain on the digital display until the condition changes.
If the engine oil temperature exceeds 320
F (160
C),
this message is displayed. You should check the engine
coolant temperature and engine oil level. If your engine
is too hot, see ªEngine Overheatingº in the Index. Your
vehicle may need service, so see your dealer. You can
monitor the oil temperature with the GAGES button on
the DIC.
HIGH TRANS TEMP (Automatic Transmission
Only): You will hear four chimes when this message is
displayed. To acknowledge this warning, press the RESET
button. After you press the RESET button, the message
will be displayed every 10 minutes until the condition
changes. If you do not press RESET, the message remains
on the display until the condition changes.
If the transmission fluid temperature rises above
270
F (132
C) or rises rapidly, this message is
displayed. The transmission may shift gears or apply the
torque converter clutch to reduce the fluid temperature.
Driving aggressively or driving on long hills can causethe transmission fluid temperature to be higher than
normal. If this message appears, you may continue to
drive at a slower speed. You should also monitor the
transmission fluid temperature and allow it to cool to at
least 230
F (110
C). The transmission fluid temperature
can be monitored with the GAGES button on the DIC.
See ªAutomatic Transmission Fluidº in the Index. You
should also check the engine coolant temperature. If it is
also hot, see ªEngine Overheatingº in the Index.
If the HIGH TRANS TEMP message is displayed during
normal vehicle operation on flat roads, your vehicle may
need service. See your dealer for an inspection.
SERVICE ACTIVE HANDLING: If the SERVICE
ACTIVE HNDLG message is displayed, there is a
problem with your Active Handling System and your
vehicle needs service. The instrument cluster light will
also be on and a chime will sound. When this message is
displayed, the system is not working. Adjust your
driving accordingly.
ACTIVE HANDLING: Your vehicle is equipped with
a computer controlled system to assist the driver in
controlling the vehicle in difficult driving conditions.
You may feel or hear the system working and see the
ACTIVE HANDLING message displayed in the DIC.
This is normal when the system is operating. Also see
ªAnti
-Lock Brakesº in the Index.
