hot or cold weather and other extreme conditions will
have an adverse effect on paint, metal trim, and under-
body protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion
resistance built into your vehicle.
What Causes Corrosion?
Corrosion is the result of deterioration or removal of
paint and protective coatings from your vehicle.
The most common causes are:
•Road salt, dirt and moisture accumulation.
•Stone and gravel impact.
•Insects, tree sap and tar.
•Salt in the air near sea-coast localities.
•Atmospheric fallout/industrial pollutants.
Washing
•
Wash your vehicle regularly. Always wash your ve-
hicle in the shade using MoparCar Wash or a mild
car wash soap, and rinse the panels completely with
clear water.
•If insects, tar, or other similar deposits have accumu-
lated on your vehicle, use MoparSuper Kleen Bug
and Tar Remover to remove.
•Use MoparCleaner Wax to remove road film, stains,
and to protect your paint finish. Take care never to
scratch the paint.
•Avoid using abrasive compounds and power buffing
that may diminish the gloss or thin out the paint
finish.
348 MAINTAINING YOUR VEHICLE

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 will 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.

SUGGESTIONS FOR OBTAINING SERVICE FOR
YOUR VEHICLE
Prepare For The Appointment
If you’re having warranty work done, be sure to have the
right papers with you. Take your warranty folder. All
work to be performed may not be covered by the
warranty, discuss additional charges with the service
manager. Keep a maintenance log of your vehicle’s
service history. This can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle’s problems or the
specific work you want done. If you’ve had an accident,
or work done that is not on your maintenance log, let the
service advisor know.
Be Reasonable With Requests
If you list a number of items, and you must have your
vehicle by the end of the day, discuss the situation with
the service advisor and list the items in order of priority.
At many dealers you may obtain a rental vehicle at a
minimal daily charge. If you need a rental, it is advisable
to make these arrangements when you call for an ap-
pointment.
IF YOU NEED ASSISTANCE
The manufacturer and its dealers are vitally interested in
your satisfaction. We want you to be happy with our
products and services.
Warranty service must be done by an authorized
Chrysler, Dodge, or Jeep dealer. We strongly recommend
that you take your vehicle to your selling dealer. They
know you and your vehicle best, and are most concerned
that you get prompt and high quality service. The
manufacturer’s dealers have the facilities, factory-trained
