Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
(Continued)
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.

Page 270 of 372

1. Turn the Mode Select Knob (5) to the Air Modeposition.
2. Uncoil the power plug and insert the plug into the vehicle’s 12 Volt power outlet.
3. Uncoil the Air Pump Hose (7) (black in color) and screw the fitting at the end of hose (7) onto the valve
stem.
4. Check the pressure in the tire by reading the Pressure Gauge (3).
If tire pressure is less than 19 psi (1.3 Bar), the tire is too
badly damaged. Do not attempt to drive the vehicle
further. Call for assistance.
If the tire pressure is 19 psi (1.3 bar) or higher:
1.
Press the Power Button (4) to turn on TIREFIT and inflate
the tire to the pressure indicated on the tire and loading
information label on the driver-side door opening.
NOTE: If the tire becomes over-inflated, press the Defla-
tion Button to reduce the tire pressure to the recom-
mended inflation pressure before continuing.
2. Disconnect the TIREFIT kit from the valve stem, reinstall the cap on the valve stem and unplug from 12
Volt outlet.
3. Place the TIREFIT kit in its proper storage area in the vehicle.
4. Have the tire inspected and repaired or replaced at the earliest opportunity at an authorized dealer or tire
service center.
5.
Replace the Sealant Bottle (1) and Sealant Hose (6)
assembly at your authorized dealer as soon as possible.
Refer to “(F) Sealant Bottle and Hose Replacement.”
NOTE: When having the tire serviced, advise the autho-
rized dealer or service center that the tire has been sealed
using the TIREFIT service kit.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote
cleaner air, your vehicle is equipped with a sophisticated
onboard diagnostic system called OBD II. This system
monitors the performance of the emissions and engine
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. 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
your authorized dealer for service as soon as possible.
CAUTION!
Prolonged driving with the light on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability. The
vehicle must be serviced before any state emissions
tests can be performed.
If the light is flashing, severe catalytic converter damage
and power loss will soon occur. Immediate service is
required.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration. For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
278 MAINTAINING YOUR VEHICLE
Page 281 of 372

Indicator Light (MIL)” is functioning and is not on when
the engine is running, and that the OBD II system is
ready for testing.
Normally, the OBD II system will be ready. The OBD II
system maynotbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery replace-
ment. If the OBD II system should be determined not
ready for the I/M test, your vehicle may fail the test.
Your vehicle has a simple ignition key-actuated test,
which you can use prior to going to the test station. To
check if your vehicle’s OBD II system is ready, you must
do the following:
1. Turn the ignition switch to the ON position, but do not crank or start the engine.
2. If you crank or start the engine, you will have to start this test over. 3. As soon as you turn the ignition switch to the ON
position, you will see the MIL symbol come on as part
of a normal bulb check.
4. Approximately 15 seconds later, one of two things will happen:
• The MIL will flash for about 10 seconds and then
return to being fully illuminated until you turn OFF
the ignition or start the engine. This means that your
vehicle’s OBD II system is not readyand you should
not proceed to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you turn OFF the ignition or start the
engine. This means that your vehicle’s OBD II system
is ready and you can proceed to the I/M station.
If your OBD II system is not ready,you should see your
authorized dealer or repair facility. If your vehicle was
recently serviced or had a battery failure or replacement,

you may need to do nothing more than drive your
vehicle as you normally would in order for your OBD II
system to update. A recheck with the above test routine
may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is
ready or not, if the MIL is illuminated during normal
vehicle operation you should have your vehicle serviced
before going to the I/M station. The I/M station can fail
your vehicle because the MIL is on with the engine
running.
REPLACEMENT PARTS
Use of genuine MOPARparts for normal/scheduled
maintenance and repairs is highly recommended to en-
sure the designed performance. Damage or failures
caused by the use of non-MOPAR parts for maintenance
and repairs will not be covered by the manufacturer’s
warranty.
DEALER SERVICE
Your authorized dealer has the qualified service person-
nel, special tools, and equipment to perform all service
operations in an expert manner. Service Manuals are
available which include detailed service information for
your vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE: Intentional tampering with emissions control
systems may void your warranty and could result in civil
penalties being assessed against you.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If
you have any doubt about your ability to perform a
service job, take your vehicle to a competent me-
chanic.

CAUTION! (Continued)
•Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, power steering or air conditioning.
Such damage is not covered by the New Vehicle
Limited Warranty. If a flush is needed because of
component malfunction, use only the specified
fluid for the flushing procedure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to

The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your authorized dealer, servicestation or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
Engine Oil Filter Selection
This manufacturer’s engines have a full-flow type oil
filter. Use a filter of this type for replacement. The quality
of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient
service. MOPAR
engine oil filters are a high quality oil
filter and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
