Vehicle Information Menu Items
T
(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” under
DIC Warnings and Messages on page 221. You
should change the oil as soon as possible. See
Engine Oil on page 337. In addition to the engine
oil life system monitoring the oil life, additional
maintenance is recommended in the Maintenance
Schedule in this manual. SeeScheduled
Maintenance on page 442for 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,
seeEngine Oil Life System on page 340.

the vehicle. See your dealer. SeeEngine Oil on
page 337andScheduled Maintenance on
page 442for more information.
Acknowledging the CHANGE ENGINE OIL SOON
message will not reset the OIL LIFE REMAINING.
That must be done at the OIL LIFE screen
under the vehicle information menu. See “Oil Life”
underDIC Controls and Displays on page 212
andEngine Oil Life System on page 340.
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 385,Loading Your Vehicle
on page 307, andInation - Tire Pressure on
page 392. The DIC display also shows the tire
pressure values for the front and rear tires by
pressing the vehicle information button. SeeDIC
Controls and Displays on page 212. If the tire
pressure is low, the low tire pressure warning light
comes on. SeeTire Pressure Light on page 205.
DRIVER DOOR OPEN
This message displays when the driver’s door is
not closed properly. When this message appears,
make sure that the driver’s door is closed
completely.
ENGINE HOT A/C
(Air Conditioning) OFF
This message displays when the engine coolant
becomes hotter than the normal operating
temperature. To avoid added strain on a hot engine,
the air conditioning compressor is automatically
turned off. When the coolant temperature returns to
normal, the A/C operation automatically resumes.
You can continue to drive your vehicle. If this
message continues to appear, have the system
repaired by your dealer as soon as possible to
avoid compressor damage.

Your vehicle’s TPMS system can warn you about a
low tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 398andTires on page 385.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable.
If the system detects a missing or inoperable
sensor, an error message SERVICE TIRE
MONITOR SYSTEM will be shown on the DIC
display. If you have replaced a tire/wheel assembly
without transferring the TPMS sensors, the error
message will be displayed. Once you re-install the
TPMS sensors, the error message should go
off. See your GM dealer for service if all TPMS
sensors are installed and the error message
comes on and stays on.Resetting the 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, or more than
ve minutes to match all four tire and wheel
positions the matching process stops and you will
need to start over.
