Monitor (TPM) system is re-learning the tire
positions on your vehicle. SeeDIC Operation and
Displays (With DIC Buttons) on page 233orDIC
Operation and Displays (Without DIC Buttons) on
page 239for more information. The tire positions
must be re-learned after rotating the tires or after
replacing a tire or sensor. SeeTire Inspection and
Rotation on page 448,Tire Pressure Monitor
System on page 444, andInflation - Tire Pressure
on page 442for more information.
TRACTION CONTROL OFF
This message displays when the Traction Control
System (TCS) is turned off. Adjust your driving
accordingly. SeeStabiliTrak
®System on page 337
for more information. This message clears itself
after 10 seconds.
TRANSMISSION HOT IDLE ENGINE
Notice:If you drive your vehicle while the
transmission uid is overheating and the
transmission temperature warning is displayed
on the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead
to costly repairs that would not be covered by
your warranty. Do not drive your vehicle with
overheated transmission uid or while the
transmission temperature warning is displayed.
This message displays along with a continuous
chime if the transmission uid in the vehicle
gets hot. Driving with the transmission uid
temperature high can cause damage to the
vehicle. Stop the vehicle and let it idle to allow
the transmission to cool. This message clears
and the chime stops when the uid temperature
reaches a safe level.

Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. TPMS sensors are mounted onto each
tire and wheel assembly, except the spare
tire. TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
The TPMS is designed to alert the driver, if a low
tire pressure condition exists. If your vehicle has the
Driver Information Center (DIC), the driver can also
check tire pressure levels using the DIC.
When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure warning
symbol located on the instrument panel cluster.
If your vehicle has the DIC feature, a message
to check the pressure in a specic tire also
appears on the DIC display. The low tire pressure
warning symbol on the instrument panel cluster
and the CHECK TIRE PRESSURE warning
message on the DIC display appears at each
ignition cycle until the tires are inated tothe correct ination pressure. For additional
information and details about the DIC operation
and displays seeDIC Operation and Displays
(With DIC Buttons) on page 233orDIC Operation
and Displays (Without DIC Buttons) on page 239
andDIC Warnings and Messages on page 244.
You may notice, during cooler weather conditions,
the tire pressure monitor light, located on the
instrument panel cluster, and the CHECK TIRE
PRESSURE message appears when the vehicle
is rst started and then turn off as you start to drive
the vehicle. This could be an early indicator that
the tire pressures are getting low and need to
be inated to the proper pressure.
Each tire, including the spare (if provided), should
be checked monthly when cold and inated to
the ination pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
ination pressure label. (If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire ination pressure label,
you should determine the proper tire ination
pressure for those tires.)
444

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.
446

The TPMS sensor matching process is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to ON with the
engine off.
3. Using the DIC, press the vehicle information
button until the PRESS
VTO RELEARN TIRE
POSITIONS message displays. If your vehicle
does not have the DIC buttons, press the trip
odometer reset stem located on the instrument
panel cluster until the RELEARN TIRE
POSITIONS message displays.
4. If your vehicle has the DIC buttons, press the
set/reset button. The horn sounds twice to
indicate the TPMS receiver is ready, and the
TIRE LEARNING ACTIVE message
displays. If your vehicle does not have the
DIC buttons, press and hold the trip odometer
reset stem until the horn chirps twice and
the TIRE LEARNING ACTIVE message
is displayed.
5. Start with the driver side front tire. The driver
side front turn signal lamp is on.6. Remove the valve cap from the 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 this
tire and wheel position.
7. Proceed to the passenger side front tire.
The passenger side front turn signal lamp is on.
Repeat the procedure in Step 6.
8. Proceed to the passenger side rear tire.
The passenger side rear turn signal lamp is on.
Repeat the procedure in Step 6.
9. Proceed to the driver side rear tire. The driver
side rear turn signal lamp is on. Repeat the
procedure in Step 6. Instead of a single horn
chirp a double horn chirp signals the TPMS
sensor has been matched to this tire and wheel
position and the matching process is no longer
active.
10. Turn the ignition switch to OFF.
11. Set all four tires to the recommended air
pressure level as indicated on the Tire and
Loading Information label.
12. Put the valve caps back on the valve stems.
447

The spare tire does not have a TPMS sensor.
If you replace one of the road tires with the spare,
the SERVICE TIRE MONITOR SYSTEM
message displays on the DIC screen. This
message should go off once you re-install the
road tire containing the TPMS sensor.
