The Tire Pressure Monitoring Telltale Lamp will
illuminate in the instrument cluster, and an au-
dible 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. The system will automatically update
and the Tire Pressure Monitoring Telltale Lamp will
extinguish once the updated tire pressures have been
received. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.
The Tire Pressure Monitoring Telltale Lamp 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.
If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. The Tire Pressure
Monitoring Telltale Lamp will turn off when the faultcondition no longer exists. 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 TPM sensors; 2) Installing some form of
aftermarket window tinting that affects radio wave sig-
nals; 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: Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle a chime will sound
and the TPM Telltale Lamp will still turn ON due to the
low tire.

3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Lamp
will flash on and off for 75 seconds and then remain on
solid.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically and the TPM Telltale
Lamp 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 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
Premium System ± If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors tomonitor tire pressure 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 check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
²Receiver module
²Four tire pressure monitoring 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 a
graphic displaying tire pressures.
²Yellow Tire Pressure Monitoring Telltale Light.

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate 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
graphic of the pressure value(s) with the low tire(s)
flashing.
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 placard pres-
sure value. The system will automatically update, the
graphic display of the pressure value(s) will stop flash-
ing, and the Tire Pressure Monitoring Telltale 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 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 ªCHECK TPM SYS-
TEMº message for three seconds. This text message is
then followed by a graphic display, with ª- - -ª in place of
the pressure value(s) indicating which tire pressure
monitoring 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 Tire Pressure Monitoring Telltale
Light will no longer flash, the9CHECK TPM SYSTEM9
text 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 scenarios: 1) Jamming due
to electronic devices or driving next to facilities emitting
the same radio frequencies as the TPM sensors;. 2)
Installing some form of aftermarket window tinting that

vehicle; 5) Using wheels/tires not equipped with TPM
sensors.
NOTE:Your vehicle is equipped with a non-matching
full size spare wheel and tire assembly.
1. This spare tire does not have a tire pressure monitor-
ing sensor. Therefore, the TPMS will not monitor the tire
pressure in the spare tire.
2. If you install the full size spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, a chime will
sound and the TPM Telltale Light will still turn ON. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. However, after driving the vehicle for up to 10 min-
utes above 15 mph (25 km/h), the TPM Telltale Light willflash on and off for 75 seconds and then remain on solid.
The EVIC will display a ªCHECK TPM SYSTEMº mes-
sage for three seconds and then display dashes (- - -) in
place of the pressure value.
4. For each subsequent ignition key cycle, a chime will
sound and the TPM Telltale Light will flash on and off for
75 seconds and then remain on solid. The EVIC will
display a ªCHECK TPM SYSTEMº message for three
seconds, and then display dashes (- - -) in place of a
pressure value.
5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the full size spare tire,
the TPMS will update automatically. In addition, the
TPM 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.

Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
²Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless 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.
(Continued)
WARNING! (Continued)
²Guard against carbon monoxide with proper
maintenance. Have the exhaust system inspected
every time the vehicle is raised. Have any abnor-
mal conditions repaired promptly. Until repaired,
drive with all side windows fully open.
²Keep the liftgate closed when driving your vehicle
to prevent carbon monoxide and other poisonous
exhaust gases from entering the vehicle.
FLEXIBLE FUEL (4.7L ENGINE ONLY) Ð IF
EQUIPPED
E-85 General Information
The information in this section is for Flexible Fuel ve-
hicles only. These vehicles can be identified by the unique
yellow fuel filler cap (gas cap) that shows E85 / Gasoline.
This section only covers those subjects that are unique to
340 STARTING AND OPERATING
ETHANOL FUEL (E-85)
E-85 is a mixture of approximately 85% fuel ethanol and
15% unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit in or near the vehicle when remov-
ing the fuel filler tube cap (gas cap) or filling the
tank. Do not use E-85 as a cleaning agent and never
use it near an open flame.
Fuel Requirements
If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with an octane rating of 87, or E-85
fuel, or any mixture of these two fuels.For best results, a refueling pattern that avoids alternat-
ing between E-85 and unleaded gasoline is recom-
mended.
When you do switch fuel types it is recommended that:
²you do not add less than 5 gal (19 L) when refueling
²you drive the vehicle immediately after refueling for at
least 5 miles (8 km)
Observing these precautions will avoid possible hard
starting and/or significant deterioration in drivability
during warm up.
NOTE:Use seasonally adjusted E-85 fuel (ASTM
D5798). With non-seasonally adjusted E-85 fuel, you may
experience hard starting and rough idle following start
up even if the above recommendations are followed,
especially when the ambient temperature is below 32ÉF
(0ÉC).
342 STARTING AND OPERATING
WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the Malfunction Indicator
Light to turn on.
NOTE:Tighten the gas cap about 1/4 turn until you
hear one click. This is an indication that cap is properly
tightened.
If the gas cap is not tightened properly, the Malfunction
Indicator Light will come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
Loose Fuel Filler Cap (Gas Cap) Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose, improperly
installed, or damaged. A loose fuel filler cap message will
be displayed in the instrument cluster. Tighten the gas
cap until a9clicking9sound is heard. This is an indication
that the gas cap is properly tightened. Press the odometer
RESET button to turn the message off. If the problem
persists, the message will appear the next time the
vehicle is started. This might indicate a damaged cap. If

WARNING!
Do not load your vehicle any heavier than the GVWR
or the maximum front and rear GAWR. If you do,
parts on your vehicle can break, or it can change the
way your vehicle handles. This could cause you to
lose control. Also, overloading can shorten the life of
your vehicle.
TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Common Towing Definitions
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or tem-
porary) loaded in or on the trailer in its9loaded and
ready for operation9condition. The recommended way to
measure GTW is to put your fully loaded trailer on a
vehicle scale. The entire weight of the trailer must be
supported by the scale.
