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.” 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 dealer for service as soon as
possible.CAUTION!
•Prolonged driving with the “Malfunction Indica-
tor 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 emissions tests can be per-
formed.
•If the “Malfunction Indicator Light” is flashing
while the engine is running, severe catalytic con-
verter damage and power loss will soon occur.
Immediate service is required.
Loose Fuel Filler Cap Message
After fuel is added, the vehicle diagnostic system can
determine if the fuel filler cap is loose or improperly
installed. A GASCAP message will be displayed in the
instrument cluster. Tighten the gas cap until aclicking

Change Engine Oil
Road conditions and your kind of driving affects the
interval at which your oil should be changed. Check the
following list to decide if any apply to you.
•Day and night temperatures are below 32°F (0°C).
•Stop and Go driving.
•Extensive engine idling.
•Driving in dusty conditions.
•Short trips of less than 10 miles (16 km).
•More than 50% of your driving is at sustained high
speeds during hot weather, above 90°F (32°C).
•Trailer towing.
•Taxi, Police or delivery service (commercial service).
•Off-Road or desert operation.NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first, and follow schedule “B—All
Engines” of theMaintenance Schedulessection of this
manual.
If none of these apply to you, then change your engine oil
at every interval shown on schedule “A” in the mainte-
nance schedule section of this manual.
NOTE:Under no circumstances should oil change in-
tervals exceed 6000 miles (10 000 km) or 6 months
whichever comes first.
Engine Oil Selection (Gasoline Engines)
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of DaimlerChrysler
Material Standard MS-6395.

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 ex-
haust system. Do not park or operate your vehicle in
areas where your exhaust system can contact any-
thing that can burn.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune up to manufacturers specifica-
tions, should be obtained immediately.
To minimize the possibility of catalyst damage:
•Do not shut off the engine or interrupt the ignition
when the transaxle 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 for prolonged period.
Crankcase Emission Control System
Proper operation of this system depends on freedom
from sticking or plugging due to deposits. As vehicle
mileage builds up, the PCV valve and passages may
accumulate deposits. If a valve is not working properly,
replace it with a new valve. DO NOT ATTEMPT TO
CLEAN THE OLD PCV VALVE!
Check ventilation hose for indication of damage or
plugging deposits. Replace if necessary.

•Use Mopar touch up paint on scratches as soon as
possible. Your dealer has touch up paint to match the
color of your vehicle.
Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil, use Mopar Wheel Cleaner or select a nonabra-
sive, non-acidic cleaner. Do not use scouring pads, steel
wool, a bristle brush or metal polishes. Only Mopar
cleaners are recommended. Do not use oven cleaner.
Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels’ protective
finish.

Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with Mopar Glass Cleaner or any commercial household-
type glass cleaner. Never use an abrasive type cleaner.
Use caution when cleaning the inside rear window
equipped with electric defrosters or the right rear quarter
window equipped with the radio antenna. Do not use
scrapers or other sharp instruments which 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.
Instrument Panel Cover
The instrument panel cover has a low glare surface which
minimizes reflections in the windshield. Do not use
protectants or other products which may cause undesir-
able reflections. Use soap and warm water to restore the
low glare surface.
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. 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 a mild soap solution or
lukewarm water. Do not remove the belts from the car to
wash them.
