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 244. You should change the oil as
soon as you can. SeeEngine Oil on page 397.
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 502for more information.
Remember, you must reset the OIL LIFE display
yourself after each oil change. It will not reset
itself. Also, be careful not to reset the OIL LIFE
display 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 400.

This message displays if there is a problem with
the StabiliTrak®system. If this message appears,
try to reset the system. Stop; turn off the engine
for at least 15 seconds; then start the engine
again. If this message still comes on, it means
there is a problem. See your dealer/retailer
for service. The vehicle is safe to drive, however,
you do not have the benet of StabiliTrak
®,
so reduce your speed and drive accordingly.
SERVICE THEFT DETERRENT SYSTEM
This message displays when there is a problem
with the theft-deterrent system. The vehicle may
or may not restart so you may want to take
the vehicle to your dealer/retailer before turning
off the engine. SeePASS-Key
®III+ Operation
on page 121for more information.
SERVICE TIRE MONITOR SYSTEM
This message displays if a part on the Tire
Pressure Monitor (TPM) system is not working
properly. If you drive your vehicle while any of
the four sensors are missing or inoperable,
the warning comes on in about 20 minutes.
A sensor would be missing, for example, if you
put different wheels on your vehicle without
transferring the sensors. If the warning comes on
and stays on, there may be a problem with the
TPM. See your dealer/retailer.
SERVICE TRACTION CONTROL
This message displays when there is a problem
with the Traction Control System (TCS). When
this message is displayed, the system will not limit
wheel spin. Adjust your driving accordingly. See
your dealer/retailer for service. SeeStabiliTrak

The Tire and Loading Information label (tire
information placard) shows the size of your
vehicle’s original tires and the correct ination
pressure for your vehicle’s tires when they are cold.
SeeInflation - Tire Pressure on page 442. For the
location of the tire and loading information label,
seeLoading Your Vehicle on page 361.
Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 448andTires on page 435.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.Resetting the TPMS Identication Codes
Each TPMS sensor has a unique identication
code. Any time you rotate your vehicle’s tires or
replace one or more of the TPMS sensors,
the identication codes need to be matched to
the new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver side front tire, passenger side front
tire, passenger side rear tire, and driver side
rear tire using a TPMS diagnostic tool. See your
dealer/retailer for service.
The TPMS sensors can also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.
To decrease air-pressure out of a tire you can use
the pointed end of the valve cap, a pencil-style
air pressure gage, or a key.
You have two minutes to match the rst tire/wheel
position, and ve minutes overall to match all
four tire/wheel positions. If it takes longer than
two minutes to match the rst tire and wheel, or
more than ve minutes to match all four tire and
wheel positions, the matching process stops and
you will need to start over.
