Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the
tire pressure after the vehicle has not been
driven for at least three hours, or driven less
than 1 mile (1.6 km) after a three-hour period.
Refer to “Tires – General Information” in
“Starting and Operating” for information on
how to properly inflate the vehicle’s tires.
The tire pressure will also increase as the
vehicle is driven - this is normal and there
should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire
pressure if the tire pressure falls below the low
pressure warning threshold for any reason,
including low temperature effects, or natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low
tire pressure as long as the condition exists,
and will not turn off until the tire pressure is at or
above recommended cold tire placard pressure.
Once the low tire pressure warning has been
illuminated, the tire pressure must be increased
to the recommended cold tire pressure in orderfor the Tire Pressure Monitoring Telltale Light to
be turned off. The system will automatically
update and the Tire Pressure Monitoring Telltale
Light will extinguish once the updated tire pres-
sures 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.
For example, your vehicle has a recommended
cold (parked for more than three hours) tire
placard pressure of 33 psi (227 kPa). If the
ambient temperature is 68°F (20°C) and the
measured tire pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is sufficiently low
enough to turn ON the Tire Pressure Monitoring
Telltale Light. Driving the vehicle may cause the
tire pressure to rise to approximately 28 psi
(193 kPa), but the Tire Pressure Monitoring
Telltale Light will still be ON. In this situation, the
Tire Pressure Monitoring Telltale Light will turn
OFF only after the tires have been inflated to the
vehicle’s recommended cold tire pressure
value.CAUTION!
•
The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures have been established for the
tire size equipped on your vehicle. Unde-
sirable system operation or sensor dam-
age may result when using replacement
equipment that is not of the same size,
type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use after-
market tire sealants or balance beads if
your vehicle is equipped with a TPMS, as
damage to the sensors may result.
• After inspecting or adjusting the tire pres-
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the Tire Pressure Monitoring Sensor.

NOTE:
•The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide warning of a tire failure or condition.
• The TPMS should not be used as a tire
pressure gauge while adjusting your tire
pressure.
• Driving on a significantly under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation also
reduces fuel efficiency and tire tread life,
and may affect the vehicle’s handling and
stopping ability.
• The TPMS is not a substitute for proper
tire maintenance, and it is the driver’s
responsibility to maintain correct tire
pressure using an accurate tire gauge,
even if under-inflation has not reached
the level to trigger illumination of the Tire
Pressure Monitoring Telltale Light.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.Base SystemThe Tire Pressure Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pres-
sure levels. 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 TPMS consists of the following compo-
nents:
•Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
A low spare tire will not cause the Tire Pressure
Monitoring Telltale Light to illuminate, a warning
message to appear, or the chime to sound. The Tire Pressure Monitoring Telltale
Light will illuminate in the instrument
cluster, a “LOW TIRE PRESSURE”
message will display in the instrument
cluster for 5 seconds, an "Inflate to XXX"mes-
sage will be displayed and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. Should this
occur, you should stop as soon as possible,
check the inflation pressure of each tire on your
vehicle, and inflate each tire to the vehicle’s
recommended cold placard pressure value dis-
played in the "Inflate to XXX" message. The
system will automatically update and the Tire
Pressure Monitoring Telltale Light will extin-
guish, once the updated tire pressures 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.
268

The Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds, and remain on
solid when a system fault is detected. In addi-
tion, a “SERVICE TPM SYSTEM” message
may be displayed for approximately 5 seconds
when a system fault is detected, and a chime
will sound. If the ignition switch is cycled, this
sequence will repeat, providing the system fault
still exists. The Tire Pressure Monitoring Telltale
Light will turn off when the fault condition no
longer exists. A system fault can occur by any of
the following:
1. Jamming due to electronic devices or driving
next to facilities emitting the same Radio Fre-
quencies 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.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, a “LOW TIRE PRESSURE”
message will be displayed in the instrument
cluster for a minimum of five seconds, an
Inflate to XXX
message will be displayed and
the Tire Pressure Monitoring Telltale Light will
turn ON. After driving the vehicle for up to 20
minutes above 15 mph (24 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”
message will be displayed for a minimum of
five seconds. For each subsequent ignition
switch cycle, a chime will sound, a “SERVICE
TPM SYSTEM” message will be displayed for
a minimum of five seconds, and the Tire Pres-
sure Monitoring 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 Telltale
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 pres-
sure levels. 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
•
Various Tire Pressure Monitoring System Mes-
sages, which display in the Electronic Vehicle
Information Center (EVIC), and a graphic dis-
playing tire pressures
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale
Light will illuminate in the instrument
cluster, and an audible chime will be
activated, when one or more of the four
active road tire pressures are low. In addition, the
EVIC will display a “LOW TIRE PRESSURE”
message for a minimum of five seconds, an
"Inflate to XXX" message and a graphic display of
the pressure value(s) with the low tire(s) “flash- ing.” Refer to “Electronic Vehicle Information Cen-
ter (EVIC)” in “Understanding Your Instrument
Panel” for further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.
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 displayed inthe
"Inflate to XXX" message. The system will
automatically update, the graphic display of the
pressure value(s) will stop “flashing,” and the
Tire Pressure Monitoring Telltale Light will extin-
guish 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
The Tire Pressure Monitoring Telltale 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 a “SERVICE TPM SYSTEM” mes-
sage for a minimum of five seconds. This mes-
sage is then followed by a graphic display, with
“- -“ in place of the pressure value(s), indicating
which Tire Pressure Monitoring Sensor(s) is not
being received.
NOTE:
Your system can be set to display pressure
units in PSI or kPa.
270
Page 275 of 408
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the Tire Pres-
sure Monitoring Telltale Light will no longer
flash, 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 driving
next to facilities emitting the same Radio Fre-
quencies 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 EVIC will also display a
"SERVICE TPM
SYSTEM" message for a minimum of five sec-
onds when a system fault is detected possibly
related to an incorrect sensor location fault. In
this case, the "SERVICE TPM SYSTEM" mes-
sage 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 but they may not be located in the
correct vehicle position. 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, the
Tire Pressure Monitoring Telltale Light will
remain ON, a chime will sound, and the EVIC
will still display a “flashing” pressure value
in the graphic display and an
Inflate to
XXX kPa message will be displayed. After
driving the vehicle for up to 20 minutes
above 15 mph (24 km/h), the Tire Pressure
Monitoring Telltale Light will flash on and off
for 75 seconds and then remain on solid. In
addition, the EVIC will display a “SERVICE
TPM SYSTEM message for five seconds
and then display dashes (- -) in place of the
pressure value. For each subsequent igni-
tion switch cycle, a chime will sound, the
Tire Pressure Monitoring Telltale Light will
flash on and off for 75 seconds and then
remain on solid, and the EVIC will display a
SERVICE TPM SYSTEM message for five
seconds and then display dashes (- -) in
place of the pressure value. 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 automatically.
271
Page 276 of 408
In addition, the Tire Pressure Monitoring Telltale
Light will turn OFF and 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 SYS-
TEM” 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. 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 displayed as long as no system fault
exists.

FUEL REQUIREMENTS —
GASOLINE ENGINE
3.6L EngineThese engines are designed to meet all emis-
sions regulations and provide excellent fuel
economy and performance when using high-
quality unleaded gasoline with a minimum re-
search octane rating of 91. The use of premium
gasoline is not recommended, as it will not pro-
vide any benefit over regular gasoline in these
engines.
5.7L EngineTheses engines are designed to meet all emis-
sions regulations and provide satisfactory fuel
economy and performance when using high-
quality unleaded gasoline having an octane
range of 91 to 95. The manufacturer recom-
mends the use of 95 octane for optimum per-
formance. The use of premium gasoline is not
recommended, 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
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.
Over 40 auto manufacturers worldwide have
issued and endorsed consistent gasoline speci-
fications (the Worldwide Fuel Charter, WWFC)
which define fuel properties necessary to de-
liver enhanced emissions, performance, and
durability for your vehicle. The manufacturer
recommends the use of gasoline that meets the
WWFC specifications if they are available.
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives may help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.Poor quality gasoline can cause problems such
as hard starting, stalling and stumble. If you
experience these problems, try another brand
of gasoline before considering service for the
vehicle.
Methanol(Methyl or Wood Alcohol) is used in a variety of
concentrations when blended with unleaded
gasoline. You may find fuels containing 3% or
more methanol along with other alcohols called
cosolvents. Problems that result from using
methanol/gasoline or E-85 Ethanol blends are
not the responsibility of the manufacturer. While
MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
CAUTION!
Do not use gasolines containing Methanol or
E-85 Ethanol. Use of these blends may result
in starting and driveability problems and may
damage critical fuel system components.
273
Page 278 of 408
EthanolThe manufacturer recommends that your ve-
hicle be operated on fuel containing no more
than 10% ethanol. Purchasing your fuel from a
reputable supplier may reduce the risk of ex-
ceeding this 10% limit and/or of receiving fuel
with abnormal properties. It should also be
noted that an increase in fuel consumption
should be expected when using ethanol-
blended fuels, due to the lower energy content
of ethanol. Problems that result from using
methanol/gasoline or E-85 ethanol blends are
not the responsibility of the manufacturer. While
MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
CAUTION!
Use of fuel with Ethanol content higher than
10% may result in engine malfunction, start-
ing and operating difficulties, and materials
degradation. These adverse effects could
result in permanent damage to your vehicle.
Clean Air GasolineMany gasolines are now being blended to con-
tribute to cleaner air, especially in those areas
where air pollution levels are high. These new
blends provide a cleaner burning fuel and some
are referred to as “reformulated gasoline.”
The manufacturer supports these efforts toward
cleaner air. You can help by using these blends
as they become available.
MMT In GasolineMMT 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 indi-
cated on the gasoline pump; therefore, you
should ask your gasoline retailer whether or not
his/her gasoline contains MMT.
Materials Added To FuelBesides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy, re-
duce emissions, and maintain vehicle perfor-
mance.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these ma-
terials intended for gum and varnish removal
may contain active solvents or similar ingredi-
ents. These can harm fuel system gasket and
diaphragm materials.

WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to pre-
vent carbon monoxide poisoning:
•Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odor-
less gas which can kill. Never run the
engine in a closed area, such as a garage,
and never sit in a parked vehicle with the
engine running for an extended period. If
the vehicle is stopped in an open area with
the engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
• Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
(Continued)
WARNING!(Continued)
•Keep the liftgate closed when driving your
vehicle to prevent carbon monoxide and
other poisonous exhaust gases from en-
tering the vehicle.
FUEL REQUIREMENTS —
DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier. For most year-round service, No. 2
diesel fuel, meeting ASTM specification D-975
Grade S15, will provide good performance. If
the vehicle is exposed to extreme cold (below
20° F or -7° C), or is required to operate at
colder-than-normal conditions for prolonged pe-
riods, use climatized No. 2 diesel fuel or dilute
the No. 2 diesel fuel with 50% No. 1 diesel fuel. This will provide better protection from fuel
gelling or wax-plugging of the fuel filters.
This
vehicle must only use premium diesel fuel
that meets the requirements of EN 590. Bio-
diesel blends that meet EN 590 may also be
used.
CAUTION!
The manufacturer requires that you must fuel
this vehicle with Ultra Low Sulfur Highway
Diesel fuel (15 ppm Sulfur maximum) and
prohibits the use of Low Sulfur Highway Diesel
fuel (500 ppm Sulfur maximum) to avoid dam-
age to the emissions control system.
275
Page 280 of 408
WARNING!
Do not use alcohol or gasoline as a fuel-
blending agent. They can be unstable under
certain conditions and hazardous or explo-
sive when mixed with diesel fuel.
Diesel fuel is seldom completely free of water.
To prevent fuel system trouble, drain the accu-
mulated water from the fuel/water separator
using the provided fuel/water separator drain. If
you buy good quality fuel and follow the cold
weather advice above, fuel conditioners should
not be required in your vehicle. If available in
your area, a high cetane “premium” diesel fuel
may offer improved cold-starting and warm-up
performance.ADDING FUEL
