Enhanced Accident Response System
In the event of an impact, if the communication network
remains intact, and the power remains intact, depending
on the nature of the event, the ORC will determine
whether to have the Enhanced Accident Response Sys-
tem perform the following functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the hazard light button is pressed. The hazard
lights can be deactivated by pressing the hazard light
button.
•Turn on the interior lights, which remain on as long as
the battery has power.
•Unlock the power door locks.
Enhanced Accident Response System Reset
Procedure
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from ignition START or ON/RUN to ignition
OFF. Carefully check the vehicle for fuel leaks in the
engine compartment and on the ground near the engine
compartment and fuel tank before resetting the system
and starting the engine.
Air Bag Warning Light
The air bags must be ready to inflate for your protection
in a collision. The Occupant Restraint Control-
ler (ORC) monitors the internal circuits and
interconnecting wiring associated with air bag
system electrical components.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the ignition switch is in
80 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

1. Tachometer
•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Electronic Vehicle Information Center (EVIC) Display
•When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center
(EVIC) messages. Refer to “Electronic Vehicle Infor-
mation Center” in “Understanding Your Instrument
Panel” for further information.
3. Speedometer
•Indicates vehicle speed.4. Fuel Gauge
•The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
5. Temperature Gauge
•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
•The gauge pointer will likely indicate a higher tem-
perature when driving in hot weather, up mountain
grades, or when towing a trailer. It should not be
allowed to exceed the upper limits of the normal
operating range.

1. Tachometer
•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Voltmeter
•When the engine is running, the gauge indicates the
electrical system voltage. The pointer should stay
within the normal range if the battery is charged. If
the pointer moves to either extreme left or right and
remains there during normal driving, the electrical
system should be serviced.
NOTE:The voltmeter may show a gauge fluctuation at
various engine temperatures. This cycling operation is
caused by the post-heat cycle of the intake manifold
heater system. The number of cycles and the length of the
cycling operation is controlled by the engine control
module. Post-heat operation can run for several minutes,
and then the electrical system and voltmeter needle will
stabilize.3. Oil Pressure Gauge
•The pointer should always indicate some oil pres-
sure when the engine is running. A continuous high
or low reading under normal driving conditions may
indicate a lubrication system malfunction. Immedi-
ate service should be obtained from an authorized
dealer.
4. Speedometer
•Indicates vehicle speed.
5. Fuel Gauge
•The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
6. Driver Information Display (DID)
•
When the appropriate conditions exist, this display
shows the Driver Information Display (DID) messages.
Refer to “Driver Information Display” in “Understand-
ing Your Instrument Panel” for further information.

WARNING!
If the stabilizer/sway bar will not return to On-Road
mode, vehicle stability is 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 or death. Contact your local service center for
assistance.

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 governmentalagency 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

conditions repaired promptly. Until repaired, drive
with all side windows fully open.
FLEXIBLE FUEL (3.6L ENGINE ONLY) — IF
EQUIPPED
E-85 General Information
The information in this section is unique for Flexible Fuel
vehicles only. These vehicles can be identified by a
unique fuel filler door label that statesEthanol (E-85) or
Unleaded Gasoline Onlyand a yellow fuel cap. Please
refer to the other sections of this manual for information
on features that are common between Flexible Fuel and
non-Flexible Fuel powered vehicles.
CAUTION!
Only vehicles with the E-85 fuel filler door label or a
yellow gas cap can operate on E-85.
Ethanol Fuel (E-85)
E-85 is a mixture of approximately 85% ethanol and 15%
unleaded gasoline.
WARNING!
Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit or products that can cause spark in or
near the vehicle when removing 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.
680 STARTING AND OPERATING

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:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
•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.
