(Vehicle Information):Press this button to
scroll through the following menu items:
Oil Life
Press the vehicle information button until OIL LIFE
REMAINING displays. This display shows an
estimate of the oil’s remaining useful life. If you
see 99% OIL LIFE REMAINING on the display,
that means 99% of the current oil life remains.
The engine oil life system will alert you to change
the oil on a schedule consistent with your
driving conditions.
When the remaining oil life is low, the CHANGE
ENGINE OIL SOON message will appear on the
display. See “CHANGE ENGINE OIL SOON”
underDIC Warnings and Messages on page 199.
You should change the oil as soon as possible.
SeeEngine Oil on page 310. In addition to the
engine oil life system monitoring the oil life,
additional maintenance is recommended in the
Maintenance Schedule in this manual. See
Scheduled Maintenance on page 408for more
information.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 cannot be reset accurately until the next oil
change. To reset the engine oil life system,

by the system while driving, a message advising
you to check the pressure in a specic tire
will appear in the display. SeeInation - Tire
Pressure on page 359andDIC Warnings
and Messages on page 199for more information.
If the tire pressure display shows dashes
instead of a value, there may be a problem with
your vehicle. If this consistently occurs, see
your dealer/retailer for service.
Learn Tire Positions
To access this display, the vehicle must be in
PARK (P). After rotating the tires or after replacing
a tire or sensor, the Tire Pressure Monitor
(TPM) system must re-learn the tire positions.
To re-learn the tire positions, seeTire Pressure
Monitor System on page 360. SeeTire Inspection
and Rotation on page 364andDIC Warnings
and Messages on page 199for more information.
Compass Zone
Your vehicle may have this feature. Under certain
circumstances, such as during a long distance
cross-country trip, it will be necessary to
compensate for compass variance and reset the
zone. To change the compass zone through
the DIC, seeDIC Compass on page 197.
Compass Calibration
The compass can be manually calibrated.
To calibrate the compass through the DIC,
seeDIC Compass on page 197.
Remote Key
To access this display, the vehicle must be in

CHECK TIRE PRESSURE
This message displays when the tire pressure in
one of the tires needs to be checked. This message
also displays LEFT FRONT, RIGHT FRONT, LEFT
REAR, or RIGHT REAR to indicate which tire needs
to be checked. You can receive more than one tire
pressure message at a time. To read the other
messages that may have been sent at the same
time, press the set/reset button. If a tire pressure
message appears on the DIC, stop as soon as you
can. Have the tire pressures checked and set to
those shown on the Tire Loading Information label.
SeeTires on page 351,Loading Your Vehicle on
page 277, andInation - Tire Pressure on
page 359. The DIC display also shows the tire
pressure values for the front and rear tires by
pressing the vehicle information button. SeeDIC
Operation and Displays on page 191. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 184.

TPMS Sensor Identication Codes
Each TPMS sensor has a unique identication
code. Any time you replace one or more of
the TPMS sensors or rotate the vehicle’s tires,
the identication codes will need to be matched
to the new tire/wheel position. The sensors
are matched, to the tire/wheel positions, in the
following order: driver’s side front tire, passenger’s
side front tire, passenger’s side rear tire, and
driver’s side rear tire using a TPMS diagnostic
tool. See your GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. When increasing the tire’s
pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
You will have two minutes to match each tire
and wheel position. If it takes longer than
two minutes to match any tire and wheel position,
the matching process stops and you will need
to start over.The TPMS matching process is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the LEARN TIRE POSITIONS
message displays.
4. Press the set/reset button to allow the system
to learn the tire positions. The horn will sound
twice to indicate the receiver is ready, and
the TIRE LEARNING ACTIVE message
will display. The TPMS system is ready for
the sensor matching process to begin.
5. Start with the driver’s side front tire.
6. Remove the valve cap from the tire’s valve
stem. Activate the TPMS sensor by increasing
or decreasing the tire’s air pressure for
ve seconds, or until a horn chirp sounds.
The horn chirp, which may take up to
30 seconds to sound, conrms that the sensor
identication code has been matched to the
tire/wheel position. To decrease the tire’s
air-pressure use the pointed end of the valve
cap, a pencil-style air pressure gage, or a key.

When rotating your tires, always use the correct
rotation pattern shown here.
Do not 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. SeeInation - Tire
Pressure on page 359andLoading Your Vehicle on
page 277.Reset the Tire Pressure Monitor System. See
“TPMS Sensor Identication Codes” under
Tire Pressure Monitor System on page 360.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 403.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after 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 needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 374.
