WARNING!(Continued)
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 or death. Contact your local service
center for assistance.

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
distance up the ramp divided by the wheelbase of the
vehicle and multiplied by 1,000 is the RTI. This vehicle

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 op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your local dealer to have your
sensor function checked.
•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 “Tire Pressure Monitor-
ing Telltale Light.”
628 STARTING AND OPERATING

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.

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.

STARTING AND OPERATING 639

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.E-85 Badge
640 STARTING AND OPERATING

Maintenance
CAUTION!
Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect drivability.
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.
Fuel Filler Cap

STARTING AND OPERATING 643

CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap.
•A poorly fitting fuel filler cap could let impurities
into the fuel system.
•A poorly fitting fuel filler cap may cause the
“Malfunction 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.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
(Continued)
WARNING!(Continued)
•Never add fuel to the vehicle when the engine is
running.
•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.
NOTE:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn
on if the gas cap is not secured properly. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
644 STARTING AND OPERATING

WARNING!
Static electricity can cause an ignition of flammable
liquid, vapor or gas in any vehicle or trailer. To
reduce risk of serious injury or death when filling
containers:
•Always place container on the ground before fill-
ing.
•Keep the pump nozzle in contact with the container
when you are filling it.
•Use only approved containers for flammable liq-
uid.
•Do not leave container unattended while filling.
•A static electric charge could cause a spark and fire
hazard.
Loose Fuel Filler Cap Message
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 EVIC/DID telltale display
area. Refer to “Electronic Vehicle Information Center
(EVIC)/Driver Information Display (DID) in “Under-
standing Your Instrument Panel” for further information.
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.
