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. AnInflate 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. An Inflate 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 aSERVICE 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.
General Information
This device complies with Part 15 of the FCC rules and
RSS 210 of Industry Canada. Operation is subject to the
following conditions:
•This device may not cause harmful interference. •
This device must accept any interference received,
including interference that may cause undesired op-
eration.

FUEL REQUIREMENTS
6.4L Engine
The 6.4L engine is designed to meet all emis-
sions regulations and provide excellent fuel
economy and performance when using high-
quality premium unleaded gasoline with an
octane rating of 91 or higher.

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.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
• Do 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)
472 STARTING AND OPERATING
Page 475 of 614
WARNING!(Continued)
•Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal
conditions repaired promptly. Until repaired, drive
with all side windows fully open.
ADDING FUEL
1. Press the fuel filler door release switch (located in the driver’s door map pocket).
2. Open the fuel filler door.

CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never 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.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. You could be
burned. Always place fuel containers on the
ground while filling.

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.

HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located in the
switch bank near the top center of the instrument panel.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position. NOTE:
With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission
in NEUTRAL, but do not increase the engine idle
speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
