FUEL INFO (Information):Press this button to display
fuel information.
Press the FUEL INFO button until the display shows
FUEL ECONOMY AVERAGE. Average fuel economy is
viewed as a long term approximation of your overall
driving conditions. To learn the average fuel economy
from a new starting point, press the RESET button while
the average fuel economy is displayed in the DIC.
Press the FUEL INFO button until the display shows
FUEL ECONOMY INST. Instantaneous fuel economy
varies with your driving conditions, such as acceleration,
braking and the grade of the road being traveled. The
RESET button does not function in this mode.
Press the FUEL INFO button until the display shows
FUEL RANGE. The fuel range will calculate the
remaining distance you can drive without refueling. This
calculation is based on the average fuel economy for
the last 25 miles (40.25 km) driven, and the fuel
remaining in the fuel tank. The RESET button does not
function in this mode.
GAGE INFO (Information):Use this button to display
oil pressure, oil life, coolant temperature, tire pressure
and battery information.Press the GAGE INFO button until OIL PRESSURE
appears in the display. If there are no problems detected
with the oil pressure, the display will show OIL
PRESSURE NORMAL. If a low oil pressure condition is
detected, the display will show OIL PRESSURE
LOW. If you see the OIL PRESSURE LOW message,
your vehicle could be low on oil or the oil is not
going through the engine properly. See your dealer
for service.
Press the GAGE INFO button until COOLANT TEMP
appears in the display. If there are no problems detected
with the temperature, COOLANT TEMP NORMAL will
appear in the display. If the temperature is too high,
COOLANT TEMP HOT will appear in the display. If you
see the COOLANT TEMP HOT message, the engine
is overheated. You should pull off the road, stop
your vehicle and turn off your engine as soon as
possible. This manual explains what to do. SeeEngine
Overheating on page 5-26.
Press the GAGE INFO button until the display shows
BATTERY STATE. If the voltage is normal the display
will show BATTERY STATE NORMAL. If the voltage
drops below 10.5 volts, the display will show BATTERY
STATE LOW. If the voltage is above 16.2 volts, the
display will show BATTERY STATE HIGH. If the display
shows the high or low message, you need to have
your battery and charging system checked.

Press the GAGE INFO button until OIL LIFE INDEX
appears in the display. The OIL LIFE INDEX NORMAL
display will show an estimate of the oil’s remaining
useful life. When the oil life index is less than 10 percent,
the display will show OIL LIFE INDEX CHANGE OIL.
When you have the oil changed according to the
maintenance schedule, you will have to reset the oil life
monitor. SeePart A: Scheduled Maintenance Services
on page 6-4. To reset the Oil Life System, see
Engine Oil on page 5-13.
Press the GAGE INFO button until TIRE PRESSURE
appears in the display. TIRE PRESSURE NORMAL
is displayed 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 CHECK TIRE PRESSURE.
If you see the CHECK TIRE PRESSURE message, you
should stop as soon as you can and check all your
tires for damage. If a tire is at, seeIf a Tire Goes Flat
on page 5-73. Also check the tire pressure in all four
tires as soon as you can. SeeInation - Tire Pressure
on page 5-65andCheck Tire Pressure System on
page 5-66. There are times when you will have to reset
(calibrate) the Check Tire Pressure System. See
Check Tire Pressure System on page 5-66.RESET:This button, used along with other buttons, will
reset system functions.
ENG/MET (English/Metric):Use this button to change
the display between English and metric units.
DIC messages can be displayed in one of three

DIC Warnings and Messages
Other messages or warnings may appear in the DIC
display. For Canadian drivers, in addition to the
DIC message your DIC will display EXP with a number
after it which reects the following messages:
EXP
(Export ID) Warning Message
20 TURN SIGNAL STILL ON?
24 TRUNK AJAR
25 WINDSHIELD WASHER FLUID LOW
27 BATTERY SAVER ACTIVE
36 ENGINE OIL LOW – CHECK LEVEL
40 THEFT ATTEMPT DETECTED
54 SERVICE STABILITY SYSTEM
55 STABILITY SYSTEM ACTIVE
61 GAS CAP LOOSE – CHECK CAP
81 CHANGE ENGINE OIL SOON
91 TRACTION CONTROL SYSTEM ACTIVE
102 CHECK CHARGE SYSTEM
139 DOOR AJAR
144 CHECK TIRE PRESSURES
The EXP codes are used to make translation from
English to other languages easier.
Pressing any of the DIC control buttons will remove the
messages or warnings from the DIC display.SERVICE STABILITY SYSTEM – 54:If you ever see
the SERVICE STABILITY SYSTEM message, it
means there may be a problem with your stability
enhancement system. If you see this message, try to
reset the system: stop, turn off the engine, then start the
engine again. If the SERVICE STABILITY SYSTEM
message still comes on, it means there is a problem.
You should see your dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message on the Driver
Information Center. It means that an advanced,
computer-controlled system has come on to help your
vehicle continue to go in the direction in which you
are steering. This stability enhancement system
activates when the computer senses that your vehicle is
just starting to spin, as it might if you hit a patch of
ice or other slippery spot on the road. When the system
is on, you may hear a noise or feel a vibration in the
brake pedal. This is normal.
When the STABILITY SYSTEM ACTIVE message is on,
you should continue to steer in the direction you want
to go. The system is designed to help you in bad
weather or other difficult driving situations by making the
most of whatever road conditions will permit. If the
STABILITY SYSTEM ACTIVE message comes on, you
will know that something has caused your vehicle to
start to spin, so you should consider slowing down.

When to Change Engine Oil (Vehicles
with the GM Oil Life System)
If equipped, your vehicle has a computer system that
lets you know when to change the engine oil and lter.
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 SOON message
will come on. Change your oil as soon as possible within
the next two times you stop for fuel. It is possible that,
if 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
lter must be changed at least once a year and at
this time the system must be reset. Your dealer has
GM-trained service people who will perform this
work using genuine GM parts and reset the system. It is
also important to check your oil regularly and keep it
at the proper level.
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.
How to Reset the Oil Life System
The GM Oil Life System calculates when to change
your engine oil and lter based on vehicle use. Anytime
your oil is changed, reset the system so it can
calculate when the next oil change is required. If a
situation occurs where you change your oil prior to a
CHANGE ENGINE OIL SOON message being
turned on, reset the system.
To reset the Oil Life System, do the following:
1. Display the OIL LIFE INDEX on the DIC.
2. Press and hold the RESET button on the DIC for
more than ve seconds. The oil life will change
to 100%.
3. Turn the key to OFF.
If the CHANGE ENGINE OIL SOON message comes
back on when you start your vehicle, the engine oil
life system has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good
hand cleaner. Wash or properly dispose of clothing or
rags containing used engine oil. See the manufacturer’s
warnings about the use and disposal of oil products.
