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 automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions 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. Al-
though 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 MIL 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 emissions
tests can be performed.
•If the MIL is flashing while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
Loose Fuel Filler Cap Message
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
“CHECK GASCAP” message will be displayed in the
Electronic Vehicle Information Center (EVIC) or Driver
Information Display (DID). Refer to “Electronic Vehicle
Information (EVIC) or#Driver Information Display
(DID)” in “Understanding Your Instrument Panel” for

further information. Tighten the fuel filler cap until a
“clicking” sound is heard. This is an indication that the
fuel filler cap is properly tightened. Refer to “Onboard
Diagnostic System” in “Maintaining Your Vehicle” for
further information.
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 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 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. Cycle the ignition switch to the ON position, but do
not crank or start the engine.
NOTE:If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON
position, you will see the MIL symbol come on as part
of a normal bulb check.

6. Install the A/C air filter with the air filter position
indicators pointing in the same direction as removal.
CAUTION!
The A/C air filter is identified with an arrow to
indicate airflow direction through the filter. Failure
to properly install the filter will result in the need to
replace it more often.
7. Install the passenger side hush panel under the dash
panel and console closeout.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as MOPAR® Spray White Lube to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latching
components to ensure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR®
Lock Cylinder Lubricant directly into the lock cylinder.7

MAINTENANCE SCHEDULE
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that ser-
vice is required for your vehicle. Operating conditions
such as frequent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence when the “Oil
Change Required” message is displayed. Severe Operat-
ing Conditions can cause the change oil message to
illuminate as early as 3,500 miles (5,600 km) since last
reset. Have your vehicle serviced as soon as possible,
within the next 500 miles (805 km).
Your authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other
than your authorized dealer, the message can be reset by
referring to the steps described under “Electronic Vehicle
Information Center (EVIC)” or “Driver Information Dis-
play (DID)” in “Understanding Your Instrument Panel”
for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 10,000 miles (16,000 km) or twelve months,
whichever comes first.
Severe Duty All Models
Change Engine Oil at 4000 miles (6,500 km) if the vehicle
is operated in a dusty and off road environment. This
type of vehicle use is considered Severe Duty.
Once A Month Or Before A Long Trip:
•Check engine oil level.
•Check windshield washer fluid level.
