The EVIC will also display aSERVICE 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 Full Size Spare
1. The matching full size spare wheel and tire assembly has a TPM sensor that can be monitored by the TPMS.
2. If you install the full size spare 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 and the TPM Telltale Light will turn ON. In addition, the EVIC will display a low pressure mes-
sage and a graphic showing the low tire pressure
value flashing or in a different color. An
Inflate to XX
message will also be displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h) the TPM Telltale Light will turn
OFF, and the pressure value displayed will be updated
and stop flashing or return to its original color as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires.
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.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the TPM

Telltale Light will remain ON and a chime will sound.
In addition, the graphic in the EVIC will still display a
flashing pressure value or a pressure value in a
different color. AnInflate to XXmessage will also be
displayed.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPM 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 a minimum of five seconds and
then display dashes (- -) in place of the pressure value.
4. 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 solid, and the EVIC
will display a SERVICE TPM SYSTEM message for a
minimum of five 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
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. 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.

FUEL REQUIREMENTS
6.4L Engine
The 6.4L engine is designed to meet all
emissions regulations and provide excellent
fuel economy and performance when using
high-quality premium unleaded gasoline
with an octane rating of 91 or higher.
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.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasolines contain oxygenates and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
(Continued)
CAUTION! (Continued)
•The 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 perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.

The bar code allows a computer scanner to read the VIN.
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total load
must be limited so that you do not exceed the GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR.
WARNING!
Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have a collision.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and the
front and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to ensure that
it is not over the GVWR.
5
STARTING AND OPERATING 467
Page 470 of 599

Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle’s
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle-by-axle and side-by-side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is withinthe specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate.
NOTE:
•
Refer to the “Vehicle Certification Label” affixed to the
rear of the driver’s door for your vehicle’s GVWR and
GAWRs.
• Refer to the “Tire Placard” for your vehicle’s proper
tire pressure.
TRAILER TOWING
Trailer towing with this vehicle is not recommended.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H,”
pull over and stop the vehicle. Idle the vehicle with
the air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “H,” turn the engine off immediately and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
TIREFIT KIT
Small punctures up to ¼” (6 mm) in the tire tread can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).
This kit will provide a temporary tire seal, allowing you
to drive your vehicle up to 100 miles (160 km) with a
maximum speed of 55 mph (88 km/hr).

3. Uncoil the Air Pump Hose (7) (black in color) andscrew the fitting at the end of hose (7) onto the valve
stem.
4. Check the pressure in the tire by reading the Pressure Gauge (3).
If tire pressure is less than 19 psi (1.3 Bar), the tire is too
badly damaged. Do not attempt to drive the vehicle
further. Call for assistance.
If the tire pressure is 19 psi (1.3 Bar) or higher:
1. Press the Power Button (4) to turn on TIREFIT and inflate the tire to the pressure indicated on the tire and
loading information label on the driver-side door
opening.
NOTE: If the tire becomes over-inflated, press the Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing. 2. Disconnect the TIREFIT kit from the valve stem,
reinstall the cap on the valve stem and unplug from
12 Volt outlet.
3. Place the TIREFIT kit in its proper storage area in the vehicle.
4. Have the tire inspected and repaired or replaced at the earliest opportunity at an authorized dealer or tire
service center.
5. Replace the Sealant Bottle (1) and Sealant Hose (6) assembly at your authorized dealer as soon as pos-
sible. Refer to “(F) Sealant Bottle and Hose Replace-
ment.”
NOTE: When having the tire serviced, advise the autho-
rized dealer or service center that the tire has been sealed
using the TIREFIT service kit.
