Other warning messages 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
23 DOOR AJAR
24 TRUNK AJAR
25 WINDSHIELD WASHER FLUID LOW
36 ENGINE OIL LOW – CHECK LEVEL
54 SERVICE STABILITY SYSTEM

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 GM dealer for service. Reduce
your speed and drive accordingly.
STABILITY SYSTEM ACTIVE – 55:You may see the
STABILITY SYSTEM ACTIVE message. 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.

Tire Pressure Status – 140:If you see the TIRE
PRESSURE LOW 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 5-64and
Check Tire Pressure System on page 5-65.
There are times when you will have to reset (calibrate)
the Check Tire Pressure System. SeeCheck Tire
Pressure System on page 5-65.
DIC Vehicle Personalization
The DIC is used to program personal choices for up to
two drivers. The drivers are recognized as DRIVER #1
and DRIVER #2. The DIC will identify a person as
UNKNOWN DRIVER if neither DRIVER #1 nor
DRIVER #2 is identied by the system. You will let the
DIC know which driver you are by using your remote
keyless entry transmitter or by pressing one of the
MEMORY buttons located on the driver’s door. Each
remote keyless entry transmitter was pre-programmed
to belong to DRIVER #1 or DRIVER #2 and is
numbered on the back. Each transmitter may be
programmed differently.After you press the unlock button on your transmitter
with the ignition to RUN, the DIC will display the
identied driver number. The vehicle will recall the
personal choice settings that were last made to
correspond to your transmitter, including your radio and
climate control settings. SeeClimate Controls
Personalization on page 3-31.
If you unlock the vehicle using the key instead of your
transmitter, the DIC will not identify the driver and
will recall the information from the last transmitter used
or the last driver using one of the MEMORY buttons.
If this happens and you were not the last driver of
the vehicle, press your correct driver number on the
appropriate MEMORY button or press the unlock button
on your transmitter.
The DIC can be used to program the following personal
choice features available with your vehicle:
Outside Curb View Assist Mirror
Programmable Automatic Door Locks
Delayed Locking
Security Feedback
Perimeter Lighting
Memory Seat Recall
Window Lock Out

The check tire pressure system detects differences in
tire rotation speeds that are caused by changes in
tire pressure. The system can alert you about a
low tire — but it does not replace normal tire
maintenance. SeeTires on page 5-58.
When the TIRE PRESSURE LOW message appears on
the Driver Information Center, 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 5-64.
Any time you adjust a tire’s pressure or have one
or more tires repaired or replaced, you will need to reset
(calibrate) the check tire pressure system. You will
also need to reset the system whenever you rotate the
tires, buy new tires and install or remove the compact
spare tire.
Do not reset the check tire pressure system without rst
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.To reset (calibrate) the system:
1. Turn the ignition switch to RUN.
2. Press the GAGE INFO button on the DIC until TIRE
PRESSURE appears on the display.
3. Press and hold the DIC RESET button for about
ve seconds. After ve seconds, the display will
show TIRE PRESSURE RESET. If TIRE
PRESSURE RESET does not appear on the
display after about ve seconds, see your dealer for
service. After you release the DIC RESET button,
TIRE PRESSURE NORMAL will appear on
the display.
The system completes the calibration process during
driving. Calibration time can take 45 to 90 minutes,
depending on your driving habits. After the system
has been calibrated, the system will alert the driver
that a tire is low, up to a maximum speed of
65 mph (105 km/h).

Tire Inspection and Rotation
Tires should be rotated every 5,000 to 8,000 miles
(8 000 to 13 000 km).
Any time you notice unusual wear rotate your tires as
soon as possible and check wheel alignment. Also
check for damaged tires or wheels. SeeWhen It Is Time
for New Tires on page 5-68andWheel Replacement
on page 5-71for more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The rst rotation
is the most important. SeePart A: Scheduled
Maintenance Services on page 6-4, for scheduled
rotation intervals.
When rotating your tires, always use the correct rotation
pattern shown here.Don’t include the compact spare tire in your tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label.
Reset the check tire pressure system, if equipped. See
Check Tire Pressure System on page 5-65.
Make certain that all wheel nuts are properly tightened.
See “Wheel Nut Torque” underCapacities and
Specications on page 5-100.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel could
come off and cause an accident. When you
change a wheel, remove any rust or dirt from
places where the wheel attaches to the vehicle.
In an emergency, you can use a cloth or a
paper towel to do this; but be sure to use a
scraper or wire brush later, if you need to, to
get all the rust or dirt off. SeeChanging a Flat
Tire on page 5-74.

Footnotes
†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.
*If your vehicle has the GM Oil Life System, a computer
system lets you know when to change the 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. See Engine Oil
on page 5-13.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 atleast 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.
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 Life System
on page 5-17 for information on resetting the system.
@Whenever the tires are rotated, the Check Tire
Pressure System (if equipped) must be reset.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-24.
