ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated Onboard
Diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and transmission
control systems. When these systems are operating prop-
erly, your vehicle will provide excellent performance and
fuel economy, as well as engine emissions well within
current government regulations.
If any of these systems require service, the OBD II system
will turn on the Malfunction Indicator Light (MIL). It will
also store diagnostic codes and other information to assist
your service technician in making repairs. Although your
vehicle will usually be drivable and not need towing, see
an authorized dealer for service as soon as possible.

tank before resetting the system and starting the engine.
If there are no fuel leaks or damage to the vehicle electrical
devices (e.g. headlights) after an accident, reset the system
by following the procedure described below.

WARNING!(Continued)
•ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for fuel,
coolant, oil, or other fluid leaks. Also, if gasoline fumes are
detected or if fuel, or brake fluid leaks are suspected. The
cause should be located and corrected immediately.

SAFETY 247

NOTE:In certain cold conditions, ice may prevent the fuel
door from opening. If this occurs, lightly push on the fuel
door to break the ice buildup and re-release the fuel door
using the inside release button. Do not pry on the door.
3. There is no fuel filler cap. Two flapper doors inside the pipe seals the system.
4. Insert the fuel nozzle fully into the filler pipe, the nozzle opens and holds the flapper doors while refueling.
5. Fill the vehicle with fuel, when the fuel nozzle “clicks” or shuts off the fuel tank is full. 6. Wait five seconds before removing the fuel nozzle to
allow fuel to drain from nozzle.
7. Remove the fuel nozzle and close the fuel door.
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors.
A funnel is provided to open the flapper doors to allow
emergency refueling with a gas can.
1. Retrieve funnel from the spare tire storage area.
2. Insert funnel into same filler pipe opening as the fuel nozzle.
3.Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.

WARNING!(Continued)
•Never add fuel when the engine is running. This is
in violation of most state and federal fire regulations
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.

After Driving Off-Road
Off-road operation puts more stress on your vehicle than
does most on-road driving. After going off-road, it is
always a good idea to check for damage. That way you can
get any problems taken care of right away and have your
vehicle ready when you need it.
•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These things
could be a fire hazard. They might hide damage to fuel
lines, brake hoses, axle pinion seals, and propeller shafts. •
After extended operation in mud, sand, water, or similar
dirty conditions, have the radiator, fan, brake rotors,
wheels, brake linings, and axle yokes inspected and
cleaned as soon as possible.

Jack Location
The scissor-type jack and tire changing tools are located in
the rear cargo area, below the load floor.
NOTE:The funnel for the Cap-Less Fuel System is located
on top of the spare tire. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle. For vehicles not
equipped with a spare tire, the fuel filler funnel is stored in
the left storage bin under the load floor. For more informa-
tion on the Cap-Less Fuel System, refer to “Refueling The
Vehicle” in “Starting And Operating”.
Spare Tire Stowage
The spare tire is stowed under the load floor in the rear cargo
area and is secured to the body with a special wing nut.
