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 drivability. 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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, a
”gASCAP” message will display in the odometer or a
“Check Gascap” message will display in the Electronic
Vehicle Information Center (EVIC) (if equipped). If this
occurs, tighten the fuel filler cap properly and press the
414 MAINTAINING YOUR VEHICLE

Trip Odometer 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 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
notbe 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. Cycle 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 cycle the ignition switch to the ON position, you will see the MIL symbol come on as part
of a normal bulb check.

MAINTAINING YOUR VEHICLE 415

4. Approximately 15 seconds later, one of two things willhappen:
• 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 MOPAR® parts 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 mainte-
nance and repairs will not be covered by the New Vehicle
Limited 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
416 MAINTAINING YOUR VEHICLE

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.
MAINTENANCE PROCEDURES
The pages that follow contain the requiredmaintenance
services determined by the engineers who designed your

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, service
station 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.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary

WARNING!(Continued)
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR® engine air
cleaner filters are a high quality filter and are recom-
mended.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required. NOTE:

Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a performance
test. Drive belt tension should also be checked at this
time.
CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.
WARNING!
•Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause the
system to fail, requiring costly repairs. Refer to
Warranty Information Book, located on the DVD,
for further warranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.

Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealer or other
service facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system
sealers, stop leak products, seal conditioners, compressor
oil, and refrigerants.
A/C Air Filter
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation. 1. Remove the access door in the cowl screen by pressing
the retaining clips.
2. Unsnap both ends and lift the filter access cover.

Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium based grease, such as
MOPAR® Spray White Lube to assure quiet, easy opera-
tion 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 compo-
nents to ensure proper function. When performing other
underhood services, the hood latch, release mechanism
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.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield periodically with a sponge or soft cloth and a
mild nonabrasive cleaner. This will remove accumula-
tions of salt or road film.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always use
washer fluid when using the wipers to remove salt or dirt
from a dry windshield.
Avoid using the wiper blades to remove frost or ice from
the windshield. Keep the blade rubber out of contact with
petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines or wet spots. If any of these conditions
are present, clean the wiper blades or replace as neces-
sary.
