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 dis-
play in the instrument cluster telltale display
area. Refer to “Instrument Cluster Display” in “Under-
standing Your Instrument Panel” for further information.
Tighten the fuel filler cap properly and push 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). 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
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 may not be ready if your vehicle was recently
serviced, or recently had a dead battery or a battery
replacement. 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 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 follow-
ing:
1. Cycle the ignition to the ON mode, but do not crank or
start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over. 7MAINTAINING YOUR VEHICLE 449

2. As soon as you cycle the ignition to the ON mode, you
will see the “Malfunction Indicator Light (MIL)” symbol
come on as part of a normal bulb check.
3. 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 cycle the ignition
OFF or start the engine. This means that your vehicle’s
OBD II system is not ready and you should not proceed
to the I/M station.
• The MIL will not flash at all and will remain fully
illuminated until you place the ignition in the off posi-
tion 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 MOPAR parts for normal/scheduled main-
tenance and repairs is highly recommended to ensure the
designed performance. Damage or failures caused by the
use of non-MOPAR parts for maintenance and repairs will
not be covered by the New Vehicle Limited Warranty.
DEALER SERVICE
Your authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
which include detailed service information for your ve-
hicle. Refer to these Service Manuals before attempting any
procedure yourself.
NOTE: Intentional tampering with emissions control sys-
tems may void your warranty and could result in civil
penalties being assessed against you.450 MAINTAINING YOUR VEHICLE

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 mechanic.
MAINTENANCE PROCEDURES
The pages that follow contain the required maintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
“Maintenance Schedule”, there are other components
which may require servicing or replacement in the future.
CAUTION!• Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately (Continued) CAUTION! (Continued)have potential malfunctions examined by an autho-
rized dealer or qualified repair center.
• 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, 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 proce-
dure.
Engine Oil
Checking Oil Level
To assure proper lubrication of your vehicle’s engine, 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 check the engine oil level is about five
minutes after a fully warmed up engine is shut off. 7MAINTAINING YOUR VEHICLE 451

Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom
of the SAFE zone will result in a reading at the top of the
safe zone on these engines.
CAUTION!Overfilling or underfilling the crankcase will cause oil
aeration or loss of oil pressure. This could damage your
engine.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to the “Maintenance Schedule” for further informa-
tion.
NOTE: Under no circumstances should oil change inter-
vals exceed 8,000 miles (13,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers. Engine Oil Selection — 6.4L Engine
