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

2. To disengage the wiper blade from the wiper arm, flip
up the release tab on the wiper blade and while
holding the wiper arm with one hand, slide the wiper
blade down towards the base of the wiper arm.

3. With the wiper blade disengaged, remove the wiper
blade from the wiper arm by holding the wiper arm
with one hand and separating the wiper blade from
the wiper arm with the other hand (move the wiper
blade toward the right side of the vehicle to separate
the wiper blade from the wiper arm).
4. Gently lower the wiper arm onto the glass.

5. Gently lower the tip of the wiper arm onto the glass.
Installing The Rear Wiper
1. Lift the rear wiper arm pivot cap away from the glass
to allow the rear wiper blade to be raised off of the
glass.
NOTE:The rear wiper arm cannot be fully raised off the
glass unless the wiper arm pivot cap is unsnapped first.
Attempting to fully raise the rear wiper arm without
unsnapping the wiper arm pivot cap may damage the
vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the opening on
the end of the wiper arm. Grab the bottom end of the
wiper arm with one hand, and press the wiper blade
flush with the wiper arm until it snaps into place.
4. Lower the wiper blade onto the glass and snap the
wiper arm pivot cap back into place.
Adding Washer Fluid
The windshield and rear window washers 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, take some
washer fluid and apply it to a cloth or towel and wipe
clean the wiper blades, 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

NOTE:Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
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 manufacturer’s specifica-
tions, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•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
idle or malfunctioning operating conditions.
Cooling System
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.

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 and/or excessive brake dust, use
MOPAR® Wheel Cleaner.
NOTE:If your vehicle is equipped with Dark Vapor or
Black Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not cov-
ered by the New Vehicle Limited Warranty. USE ONLY
MILD SOAP AND WATER WITH A SOFT CLOTH. Used
on a regular basis this is all that is required to maintain
this finish.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
or metal polishes. Do not use oven cleaner. These
products may damage the wheel’s protective finish.
Avoid automatic car washes that use acidic solutions
or harsh brushes that may damage the wheel’s pro-
tective finish. Only MOPAR® Wheel Cleaner or
equivalent is recommended.
Stain Repel Fabric Cleaning Procedure — If
Equipped
Stain Repel seats may be cleaned in the following man-
ner:
•Remove as much of the stain as possible by blotting
with a clean, dry towel.
•Blot any remaining stain with a clean, damp towel.

MAINTAINING YOUR VEHICLE 701

•For tough stains, apply MOPAR® Total Clean, or a
mild soap solution to a clean, damp cloth and remove
stain. Use a fresh, damp towel to remove soap residue.
•For grease stains, apply MOPAR® Multi-Purpose
Cleaner to a clean, damp cloth and remove stain. Use
a fresh, damp towel to remove soap residue.
•Do not use any harsh solvents or any other form of
protectants on Stain Repel products.
Interior Care
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
undesirable reflections. Use soap and warm water to
restore the low glare surface.
Cleaning Interior Trim
Clean interior trim with a damp cloth and MOPAR®
Total Clean or equivalent, and if necessary, follow with
MOPAR® Spot & Stain Remover or equivalent. Do not
use harsh cleaners or Armor All®. Use MOPAR® Total
Clean or equivalent to clean vinyl upholstery.
Cleaning Leather Upholstery
MOPAR® Total Clean or equivalent is specifically recom-
mended for leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPAR® Total Clean or equivalent. Care should be
taken to avoid soaking leather upholstery with any
liquid. Please do not use polishes, oils, cleaning fluids,

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. 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 cloth.
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. Dry with a soft cloth.
Replace the belts if they appear frayed or worn or if the
buckles do not work properly.
