The TPMS consists of the following components:
•Receiver module,
•Four TPM sensors,
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and
•TPM Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “TPM Telltale Light” will illuminate in the
instrument cluster and a chime will sound when
tire pressure is low in one or more of the four
active road tires. In addition, the EVIC will display a
“LOW TIRE” message and a graphic showing the pres-
sure values of each tire with the low tire pressure values
flashing. Should this occur, you should stop as soon as possible
and inflate all of the tires with a low pressure condition
(those flashing in the EVIC graphic) to the vehicle’s
recommended cold placard pressure inflation value.
Once the system receives the updated tire pressures, the
system will automatically update, the graphic display in
the EVIC will stop flashing, and the “TPM Telltale Light”5

will turn off. 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.
Service TPMS Warning
If a system fault is detected, the “TPM Telltale Light” will
flash on and off for 75 seconds and then remain on solid.
The system fault will also sound a chime. In addition, the
EVIC will display aSERVICE TPM SYSTEM message
for a minimum of five seconds and then display dashes (-
-) in place of the pressure value to indicate which sensor
is not being received.

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the “TPM Telltale Light” will no longer
flash, and theSERVICE TPM SYSTEM message will no
longer display, and a pressure value will display in place
of the dashes. A system fault can occur due to any of the
following:
1. Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
2. Installing aftermarket window tinting that contains
materials that may block radio wave signals.
3. Accumulation 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 EVIC will also display a
SERVICE TPM SYSTEM
message for a minimum of five seconds when a system
fault related to an incorrect sensor location fault is
detected. In this case, the SERVICE TPM SYSTEM
message is then followed with a graphic display with
pressure values still shown. This indicates that the pres-
sure values are still being received from the TPM sensors
but they may not be located in the correct vehicle
position. The system still needs to be serviced as long as
the SERVICE TPM SYSTEM message is displayed.
Vehicles with Compact Spare
1. The compact spare tire does not have a TPM sensor.
Therefore, the TPMS will not monitor the pressure in the
compact spare tire.

The TPM sensors are regulated under one of the follow-
ing licenses:

FUEL REQUIREMENTS
3.6L and 5.7L Engine (with Automatic
Transmission)
The 3.6L and 5.7L engine (with automatic
transmission) is designed to meet all emis-
sions regulations and provide satisfactory
fuel economy and performance when us-
ing high-quality unleaded gasoline having
an octane range of 87 to 89. The manufac-
turer recommends the use of 89 octane for optimum
performance. The use of premium gasoline is not recom-
mended, as it will not provide any benefit over regular
gasoline in these engines. Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World
Wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications, if they are available.5
