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 emissions 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
If the vehicle diagnostic system determines that the fuel
filler cap is loose, improperly installed, or damaged, 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

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may indicate severe
and abnormal catalyst overheating. If this should occur,
safely bring the vehicle to a complete stop, shut the
engine OFF, and allow the vehicle to cool. Thereafter,
obtain service, including a tune-up to manufacturer’s
specifications immediately.To minimize the possibility of catalyst damage:•Do not shut off the engine or interrupt the ignition
when the transmission is in gear and the vehicle is in
motion.
•Do not try to start the engine by pushing or towing the
vehicle.
•Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idling or malfunctioning operating conditions.

Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealers 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 — If Equipped
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. To
replace the filter, remove the access door in the cowl
screen by pressing the retaining clips. Slide the lid on the
filter adapter forward and down and remove the usedfilter. Install the new filter with arrows pointing in the
direction of airflow, which is toward the rear of the
vehicle (text and arrows on the filter indicate this).
Refer to the Maintenance Schedule in Section 8 for the
recommended air conditioning filter replacement inter-
vals.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through an autho-
rized dealer. No chemical flushes should be used in any
power steering system; only the approved lubricant may
be used.
400 MAINTAINING YOUR VEHICLE

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 MoparLock
Cylinder Lubricant or equivalent directly into the lock
cylinder.
Windshield Wiper Blades
The rubber edges of the wiper blades and the windshield
should be cleaned periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accu-
mulations 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.
Windshield Washers/Headlight Washers
The windshield washer and the headlight washer share
the same fluid reservoir. The fluid reservoir is located in
the front of the engine compartment. Be sure to check the
fluid level in the reservoir at regular intervals. Fill the
reservoir with windshield washer solvent (not radiator
antifreeze) and operate the system for a few seconds to
flush out the residual water.
When refilling the washer fluid reservoir, apply some
washer fluid to a cloth or towel and wipe the wiper
blades clean. This will help blade performance.
To prevent freeze-up of your windshield washer system
in cold weather, select a solution or mixture that meets or
exceeds the temperature range of your climate. This
rating information can be found on most washer fluid
containers.
402 MAINTAINING YOUR VEHICLE

Cleaning Headlights
Your vehicle has plastic headlights that are lighter and
less susceptible to stone breakage than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MoparGlass Cleaner or any commercial
household-type glass cleaner. Never use an abrasive type
cleaner. Use caution when cleaning the inside rear win-
dow equipped with electric defrosters or the right rearquarter window equipped with the radio antenna. Do
not use scrapers or other sharp instrument that may
scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or rag that you are using. Do not spray cleaner
directly on the mirror.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this vehicle are
molded in clear plastic. When cleaning the lenses, care
must be taken to avoid scratching the plastic.
1. Clean with a wet soft rag or micro-fiber towel. A mild
soap solution may be used, but do not use high alcohol
content or abrasive cleaners. If soap is used, wipe clean
with a clean damp rag.
2. Dry with a soft tissue.

Seat Belt Maintenance
Do not bleach, dye, or clean the belts with chemical
solvents or abrasive cleaners. This will weaken the fabric.
Sun damage can also weaken the fabric.
If the belts need cleaning, use MoparTotal Clean, a mild
soap solution, or lukewarm water. Do not remove the
belts from the vehicle to wash them.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
Cleaning the Center Console Cupholders
Clean with a damp cloth or towel using a mild detergent
with the cupholder in the center console.
NOTE:The cupholder cannot be removed.
FUSES (POWER DISTRIBUTION CENTERS)
Fuses (Front Power Distribution Center)
A power distribution center is located in the engine
compartment. This center contains fuses and relays.
