message will be displayed in the instrument
cluster, and the “Tire Pressure Monitoring
Telltale Light” will turn ON. After driving the
vehicle for up to 20 minutes above 15 mph
(25 km/h), the “Tire Pressure Monitoring
Telltale Light” will flash on and off for
75 seconds and then remain on solid. In
addition, a “SERVICE TPM SYSTEM” mes-
sage will be displayed. For each subsequent
ignition switch cycle, a chime will sound, a
“SERVICE TPM SYSTEM” message will be
displayed, and the “Tire Pressure Monitor-
ing Telltale Light” will flash on and off for
75 seconds and then remain on solid. Once
you repair or replace the original road tire,
and reinstall it on the vehicle in place of the
spare tire, the TPMS will update automati-
cally and the “Tire Pressure Monitoring Tell-
tale Light” will turn OFF, as long as no tire
pressure is below the low-pressure warning
limit in any of the four active road tires. The
vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) in order
for the TPMS to receive this information.Premium System – If EquippedThe Tire Pressure Monitor System (TPMS) uses
wireless technology with wheel rim-mounted
electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of
the valve stem, transmit tire pressure readings
to the Receiver Module.
NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your
tires and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS) con-
sists of the following components:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
• Various Tire Pressure Monitoring System
Messages, which display in the Electronic
Vehicle Information Center (EVIC), and a
graphic displaying tire pressures Tire Pressure Monitoring Low Pressure
Warnings
When one or more of the four active road tire
pressures are low, the “TPM Telltale Light” will
illuminate, an audible chime will sound, the
EVIC will display “Low Tire Pressure” message
for a minimum of five seconds, and a graphic
display of the pressure value(s) with the low
tire(s) “flashing.” Refer to “Electronic Vehicle
Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.
237

Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible, and inflate the low tire(s) that is
“flashing” on the graphic display to the vehi-
cle’s recommended cold tire pressure. The
system will automatically update, the graphic
display of the pressure value(s) will stop “flash-
ing,” and the Low Pressure text message(s) will
switch off once the updated tire pressure(s)
have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
SERVICE TPM SYSTEM Warning
When a system fault is detected, the “TPM
Telltale Light” will flash on and off for 75 sec-
onds then remain on solid, and a chime will
sound. The EVIC will display a “SERVICE TPM
SYSTEM” message. This message is then fol-
lowed by a graphic display, with “- -“ in place of
the pressure value(s), indicating which Tire
Pressure Monitoring Sensor(s) is not being re-
ceived.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.If the ignition switch is cycled, this sequence
will repeat, providing the system fault still ex-
ists. If the system fault no longer exists, the
“TPM Telltale Light” will no longer be illumi-
nated, the “SERVICE TPM SYSTEM
message
will not be present, and a pressure value will be
displayed instead of dashes. A system fault
can occur by any of the following:
1. Jamming due to electronic devices or driv-
ing next to facilities emitting the same Radio
Frequencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals. 3. Lots of snow or ice around the wheels or
wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM
sensors.
The “TPM Telltale Light” will also flash on and
off for 75 seconds and then remain on, and the
EVIC will display a
SERVICE TPM SYSTEM 
message when a system fault is detected pos-
sibly related to an incorrect sensor location
fault. In this case, the SERVICE TPM SYSTEM 
message is then followed by a graphic display,
with pressure values still shown. This indicates
the pressure values are still being received
from the TPM Sensors. However, the system
still needs to be serviced as long as the SER-
VICE TPM SYSTEM message exists.
NOTE:
There is no tire pressure monitoring sensor
in the spare tire. The TPMS will not be able to
monitor the tire pressure. If you install the
spare tire in place of a road tire that has a
pressure below the low-pressure warning
limit, upon the next ignition switch cycle, a
chime will sound, the TPM Telltale Light 
238

will turn on, and the EVIC will still display a
Low Pressure message and a “flashing”
pressure value in the graphic display. After
driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), theTPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
“SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. For each subsequent ignition switch
cycle, a chime will sound, the TPM Telltale
Light will flash on and off for 75 seconds
and then remain on, the EVIC will display a
 SERVICE TPM SYSTEM message and then
display dashes (- -) in place of the pressure
value. Once you repair or replace the origi-
nal road tire, and reinstall it on the vehicle in
place of the spare tire, the TPMS will update
automatically.
In addition, the graphic in the EVIC will display
a new pressure value instead of dashes (- -), as
long as no tire pressure is below the low-
pressure warning limit in any of the four active
road tires. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in
order for the TPMS to receive this information.TPMS DeactivationThe TPMS can be deactivated if replacing all
four wheel and tire assemblies (road tires) with
wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter
wheel and tire assemblies on your vehicle To
deactivate the TPMS, first, replace all four
wheel and tire assemblies (road tires) with tires
not equipped with Tire Pressure Monitoring
(TPM) Sensors. Then, drive the vehicle for
20 minutes above 24 km/h (15 mph). The TPMS
will chime, the TPM Telltale Light will flash on
and off for 75 seconds and then remain on and
the Electronic Vehicle Information Center
(EVIC) will display the “SERVICE TPM SYSTEM”
message and then display dashes (--) in place
of the pressure values. Beginning with the next
ignition switch cycle, the TPMS will no longer
chime or display the “SERVICE TPM SYSTEM”
message in the EVIC but dashes (--) will remain
in place of the pressure values.
To reactivate the TPMS, replace all four wheel
and tire assemblies (road tires) with tires
equipped with TPM sensors. Then, drive the
vehicle for up to 20 minutes above 24 km/h
(15 mph). The TPMS will chime, the TPM Telltale Light
will flash on and off for 75 sec-
onds and then turn off, and the Electronic
Vehicle Information Center (EVIC) will display
the “SERVICE TPM SYSTEM” message as long
as no system fault exists. The EVIC will also
display pressure values in place of the dashes,
on the next ignition switch cycle the SERVICE
TPM SYSTEM message will no longer be dis-
played as long as no system fault exists.

•
When installing the totally integrated power
module cover, it is important to ensure the
cover is properly positioned and fully
latched. Failure to do so may allow water to
get into the totally integrated power module
and possibly result in a electrical system
failure.
• When replacing a blown fuse, it is important
to use only a fuse having the correct am-
perage rating. The use of a fuse with a
rating other than indicated may result in a
dangerous electrical system overload. If a
properly rated fuse continues to blow, it
indicates a problem in the circuit that must
be corrected.
VEHICLE STORAGEIf you are leaving your vehicle dormant for more
than 21 days you may want to take steps to
protect your battery. You may:
• Remove fuse #27 in the Totally Integrated
Power Module (TIPM) labeled Ignition-Off
Draw (IOD#1).
