NOTE:It is particularly important to regularly check
and maintain proper tire pressure in all the tires.
The Premium TPMS consists of the following compo-
nents:
²Receiver Module
²Four TPMS Sensors
²Three Trigger Modules (mounted in three of the four
wheel wells)
²Various TPMS Messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and graph-
ics displaying tire pressures
²Yellow TPMS Telltale Warning Light
TPMS Low Pressure Warnings
The TPMS Telltale Warning Light will illuminate in the
instrument cluster, and an audible chime will be acti-
vated when one or more of the four active road tirepressures are low. In addition, the EVIC will display one
or more Low Pressure messages (Left Front, Left Rear,
Right Front, Right Rear) for three seconds, and a graphic
display of the pressure value(s) with the low tire(s)
flashing.Low Tire Pressure Display

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 vehicle's recommended cold tire pressure
value. The system will automatically update, the graphic
display of the pressure value(s) will stop flashing, and
the TPMS Telltale Warning Light will extinguish once the
updated tire pressure(s) have been received. The vehicle
may need to be driven for up to 10 minutes above 15 mph
(25 km/h) to receive this information.
Check TPMS Message
The TPMS Telltale Warning Light will flash on and off for
75 seconds, and remain on solid when a system fault is
detected. The system fault will also sound a chime. The
EVIC will display aCHECK TPM SYSTEMmessage for
three seconds. This text message is then followed by a
graphic display, with--in place of the pressure value(s)
indicating which TPMS Sensor(s) is not being received.If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the TPMS Telltale Warning Light will no
longer flash, theCHECK TPM SYSTEMtext messageCheck TPM System Display

will not be present, and a pressure value will be dis-
played instead of dashes. A system fault can occur by any
of the following scenarios:
1. Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPMS sensors.
NOTE:
1. The compact spare tire (if equipped) does not have a
TPMS. Therefore, the TPMS will not monitor the pressure
in the compact spare tire.2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, the TPMS Telltale
Warning Light will remain on, a chime will sound, and
the EVIC will still display a flashing pressure value in the
graphic display.
3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h), the TPMS Telltale Warning Light will
flash on and off for 75 seconds and then remain on solid.
In addition, the EVIC will display a9CHECK TPM
SYSTEM9message for three seconds and then display
dashes (- -) in place of the pressure value.
4. For each subsequent ignition key cycle, a chime will
sound, the TPMS Telltale Warning Light will flash on and
off for 75 seconds and then remain on solid, and the EVIC
will display a CHECK TPM SYSTEM message for three
seconds and then display dashes (- -) in place of the
pressure value.

5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
TPMS Telltale Warning Light will turn off and the
graphic in the EVIC will display a new pressure value
instead of dashes (- -), as long no tire pressure is below
the low pressure warning limit in any of the four active
road tires.
NOTE:The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.General Information

FUEL REQUIREMENTS
3.3L & 3.8L Gasoline Engine
All engines are designed to meet all emis-
sions regulations and provide excellent
fuel economy and performance when us-
ing high-quality unleaded ªregularº gaso-
line having an octane rating of 87. The use
of premium gasoline is not recommended.
Under normal conditions, the use of premium gasoline
will not provide a benefit over high-quality regular
gasolines, and in some circumstances may result in
poorer performance.
4.0L Gasoline Engine
The 4.0L engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance whenusing high-quality unleaded gasoline having an octane
range of 87 to 89. The manufacturer recommends the use
of 89 octane for optimum performance. The use of
premium gasoline is not recommended. Under normal
conditions, the use of premium gasoline will not provide
a benefit over high-quality regular and mid-grade gaso-
lines, and in some circumstances may result in poorer
performance.
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 experience these
symptoms, try another brand of ªregularº gasoline be-
fore considering service for the vehicle.

Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as ªReformulated Gasolineº.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle.
CAUTION!
DO NOT use gasolines containing Methanol or E85
Ethanol. Use of these blends may result in starting
and driveability problems and may damage critical
fuel system components.
Problems that result from using methanol/gasoline or
E85 Ethanol blends are not the responsibility of the
380 STARTING AND OPERATING
Page 383 of 531

manufacturer. While MTBE is an oxygenate made from
Methanol, it does not have the negative effects of Metha-
nol.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT.It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel.

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle's
performance:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
²An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter to
overheat. If you notice a pungent burning odor orsome light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
²The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these
products contain high concentrations of methanol.
Fuel system damage or vehicle performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
