perform the following: Place the ignition in the ON/
RUN, but do not start the engine. With the odometer
value displayed, hold the TRIP button down for a period
of six seconds. The odometer will change to trip value
first, then it will display the engine hour value. The
engine hours will be displayed for a period of 30 seconds
until the ignition is turned OFF or the engine is started.
If equipped, some of the above warnings will be dis-
played in the Electronic Vehicle Information Center
(EVIC) in the instrument cluster. Refer to ”Electronic
Vehicle Information Center (EVIC) — If Equipped” for
further information.
ECO / ECO-ON (Fuel Saver Indicator) — If Equipped
The ECO-ON indicator will illuminate when you are
driving in a fuel efficient manner and can be used to
modify driving habits in order to increase fuel economy.
The ECO display will toggle between ECO and ECO-ON
depending on driving habits and vehicle usage. Press theOdometer / Trip Odometer / ECO (Fuel Saver Indicator)
button to change the display from odometer to either of
the two trip odometer settings or the “ECO” display.
If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the odometer display area.
Tighten the fuel filler cap properly and press
the TRIP button to turn off the message. If the
problem continues, the message will appear
the next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).
Lo tirE
When the appropriate condition exists, the odometer
display will toggle between Lo and tirE for three cycles.

•Transmission Temperature LightThis light indicates that there is excessive trans-
mission fluid temperature that might occur
with severe usage such as trailer towing. It may
also occur when operating the vehicle in a high
torque converter slip condition, such as 4-wheel-drive
operation (e.g., snow plowing, off- road operation). If this
light comes on, stop the vehicle and run the engine at idle
or faster, with the transmission in NEUTRAL until the
light goes off.
CAUTION!
Continuous driving with the Transmission Tempera-
ture Indicator illuminated will eventually cause se-
vere transmission damage or transmission failure.
WARNING!
If the Transmission Temperature Warning Light is
illuminated and you continue operating the vehicle,
in some circumstances you could cause the fluid to
boil over, come in contact with hot engine or exhaust
components and cause a fire.
•Loose Gascap Indicator If the vehicle diagnostic system determines
that the fuel filler cap is loose, improperly
installed, or damaged, a loose gascap indicator
will display in the telltale display area. Tighten
the fuel filler cap properly and press the SELECT button
to turn off the message. If the problem continues, the
message will appear the next time the vehicle is started.
A loose, improperly installed, or damaged fuel filler cap
may also turn on the Malfunction Indicator Light (MIL).

WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is greatly reduced. Do not
attempt to drive the vehicle over 18 mph (29 km/h).
Driving faster than 18 mph (29 km/h) may cause loss
of control of the vehicle, which could result in
serious injury. Contact your local service center for
assistance.
SAFE OFF-ROAD DRIVING — POWER WAGON
ONLY
Off-Road Driving Tips And Vehicle Characteristics
Your vehicle has excellent on and off-road capabilities.
These off-road capabilities will allow you to explore
those wilderness trails where few travel, providing a
source of exciting and satisfying recreation. Before you
venture out, you should contact your local governmental
agency to determine the designated off-road vehicle(ORV) trails or recreation areas. You should always tread
lightly and only use established roads, trails or ORV
recreational areas. The National Forest Service, Bureau of
Land Management or local Department of Natural Re-
sources are a wealth of information and usually have
maps with marked trails.
Skid Plates And Underbody Protection
Steel skid plates protect the major driveline components
of the truck including the fuel tank, transfer case and
steering damper. In addition, this vehicle is equipped
with boxed cross members and fore/aft rails. This addi-
tional protection allows the vehicle to be utilized in
severe off-road situations that would be considered im-
passable by a normal truck.
Ramp Travel Index (RTI)
The ramp travel index is the distance, in inches, that you
can drive your vehicle with one wheel on a 20-degree
ramp without lifting any other wheel off the ground. This

CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket 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 pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the TPM sensor.NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance or to provide 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 mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the TPM Telltale Light.

WARNING! (Continued)
•Guard 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.
FLEXIBLE FUEL (4.7L ENGINE ONLY) — IF
EQUIPPED
E-85 General Information
The information in this section is for Flexible Fuel ve-
hicles only. These vehicles can be identified by a unique
fuel filler door label that statesEthanol (E-85) or Un-
leaded Gasoline Only. This section only covers those
subjects that are unique to these vehicles. Please refer to
the other sections of this manual for information on
features that are common between Flexible Fuel and
gasoline-only powered vehicles.
CAUTION!
Only vehicles with the E-85 fuel filler door label can
operate on E-85.
E-85 Fuel Cap
448 STARTING AND OPERATING
Page 451 of 636
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
Your vehicle will operate on both unleaded gasoline with
an octane rating of 87, or E-85 fuel, or any mixture of
these two. For best results, a refueling pattern that
alternates between E-85 and unleaded gasoline should be
avoided.
When you do switch fuel types it is recommended that:
•you do not switch when the fuel gauge indicates less
than 1/4 full

ADDING FUEL
The fuel filler cap (gas cap) is located behind the fuel
filler door, on the left side of the vehicle. Open the fuel
door and remove the fuel cap by turning it counter-
clockwise.NOTE:
When removing the fuel filler cap, lay the cap
tether in the hook, located on the fuel filler door.
CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the “Malfunc-
tion Indicator Light (MIL)” to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. When the fuel
nozzle “clicks” or shuts off, the fuel tank is full.
