Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice and those that are sprayed on
trees and road surfaces during other seasons are highly
corrosive to the metal in your vehicle. Outside parking,
which exposes your vehicle to airborne contaminants,
road surfaces on which the vehicle is operated, extreme
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 seacoast localities.
• Atmospheric fallout/industrial pollutants.
7 MAINTAINING YOUR VEHICLE 591

Washing
• Wash your vehicle regularly. Always wash your ve-
hicle in the shade using MOPAR  Car Wash or equiva-
lent, 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 MOPAR  Super Kleen Bug
and Tar Remover or equivalent to remove.
• Use a high quality cleaner wax, such as MOPAR 
Cleaner Wax or equivalent, 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. CAUTION!• Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder that will
scratch metal and painted surfaces.
• Use of power washers exceeding 1,200 psi (8 274 kPa)
can result in damage or removal of paint and decals.
Special Care
• If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
• It is important that the drain holes in the lower edges
of the doors, rocker panels, and trunk be kept clear and
open.592 MAINTAINING YOUR VEHICLE

• If you detect any stone chips or scratches in the paint,
touch them up immediately. The cost of such repairs is
considered the responsibility of the owner.
• If your vehicle is damaged due to a collision or similar
cause that destroys the paint and protective coating,
have your vehicle repaired as soon as possible. The
cost of such repairs is considered the responsibility of
the owner.
• If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., be sure that such materials are well
packaged and sealed.
• If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.
• Use MOPAR  Touch Up Paint or equivalent on
scratches as soon as possible. Your authorized 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 and/or excessive brake dust, use
MOPAR  Wheel Cleaner or equivalent or select a
non-abrasive, non-acidic cleaner.
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.
7 MAINTAINING YOUR VEHICLE 593

Interior Care
Use MOPAR  Total Clean or equivalent to clean fabric
upholstery and carpeting.
Interior Trim should be cleaned starting with a damp
cloth, a damp cloth with MOPAR  Total Clean or equiva-
lent , then MOPAR  Spot & Stain Remover or equivalent
if absolutely necessary. Do not use harsh cleaners or
Armor All  . Use MOPAR  Total Clean or equivalent to
clean vinyl upholstery.
WARNING!Do not use volatile solvents for cleaning purposes.
Many are potentially flammable and, if used in
closed areas, they may cause respiratory harm. CAUTION!When installing hanging air fresheners in your ve-
hicle, read the installation instructions carefully.
Some air fresheners will damage the finish of
painted or decorated parts if allowed to directly
contact any surface.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR  Glass Cleaner or equivalent, or any com-
mercial household-type glass cleaner. Never use an abra-
sive 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 instrument
that may scratch the elements.594 MAINTAINING YOUR VEHICLE

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 MOPAR  Total Clean or
equivalent, a mild soap solution, or lukewarm water. Do
not remove the belts from the vehicle 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.
Appearance Care For Fabric Top Models
CAUTION!To maintain the appearance of your vehicle’s interior
trim and top, follow these precautions:
• Avoid leaving your vehicle unattended with the top
down, as exposure to sun or rain may damage interior
trim.
• Do not use harsh cleaners or bleaching agents on top
material, as damage may result.
7 MAINTAINING YOUR VEHICLE 595

• Do not allow any vinyl cleaner to run down and dry
on the paint, leaving a streak.
• After cleaning your vehicle’s fabric top, always make
sure it is completely dry before lowering.
• Be especially careful when washing the windows by
following the directions for “Care of Fabric Top Win-
dows.”
WASHING — Use MOPAR  Car Wash or equivalent, or
mild soap suds, lukewarm water, and a brush with soft
bristles. If extra cleaning is required, use MOPAR  Con-
vertible Cloth Top Cleaner or equivalent, or a mild
foaming cleaner on the entire top, but support the top
from underneath.
RINSING — Be sure to remove all traces of cleaner by
rinsing the top thoroughly with clean water. Remember
to allow the top to dry before lowering it. CAUTION!Failure to follow these cautions may cause interior
water damage, stains or mildew on the top material:
• Avoid high-pressure car washes, as they can dam-
age the top material. Also, increased water pressure
may force past the weather strips.
• It is recommended that the top be free of water
prior to opening it. Operating the top, opening a
door or lowering a window while the top is wet
may allow water to drip into the vehicle’s interior.
• Use care when washing the vehicle, water pressure
directed at the weather strip seals may cause water
to leak into the vehicle’s interior.
• Careless handling and storage of the removable
roof panels may damage the seals, causing water to
leak into the vehicle’s interior. (Continued)596 MAINTAINING YOUR VEHICLE

CAUTION! (Continued)• The front panel(s) must be positioned properly to
ensure sealing. Improper installation can cause
water to leak into the vehicle’s interior.
Care Of Fabric Top Windows
CAUTION!Your vehicle’s fabric top has pliable plastic windows
which can be scratched unless special care is taken by
following these directions:
1. Never use a dry cloth to remove dust. Instead, use a
microfiber towel or soft cotton cloth moistened with
cold or warm, clean water, and wipe across the
window, not up and down. MOPAR  Jeep Soft Glass
Window Cleaner or equivalent will safely clean all plastic windows without scratching. It removes fine
scratches to improve visibility and provides UV pro-
tection to help prevent yellowing.
2. When washing, never use hot water or anything
stronger than a mild soap. Never use solvents such as
alcohol or harsh cleaning agents.
3. Always rinse thoroughly with cold water, then wipe
with a soft and slightly moist, clean cloth.
4. When removing frost, snow or ice, never use a scraper
or de-icing chemicals. Use warm water only if you
must clean the window quickly.
5. Debris (sand, mud/dirt, dust, or salt) from off-road
driving will have a major impact on zipper operation.
Even normal on-road driving and vehicle washing
will eventually impact window zipper operation. To
maintain ease of use of the window zippers, each
window zipper should be cleaned and lubricated
7 MAINTAINING YOUR VEHICLE 597

regularly. Use MOPAR  Soft Top Zipper Cleaner and
Lubricant or equivalent to ease zipper operation.
Before applying, make sure the zipper teeth are clear
of sand, mud, and other materials. Clean both sides of
the zipper, not just one side. Rinse both zipper halves
with fresh water and allow to dry. Aggressively work
the MOPAR  Soft Top Zipper Cleaner and Lubricant
or equivalent into the zipper teeth. If a stuck zipper
slide is experienced, work the MOPAR  Soft Top
Zipper Cleaner and Lubricant or equivalent into the
zipper slide. Several applications may be required
before the zipper comes free.
6. Never paste stickers, gummed labels or any tape to the
windows. Adhesives are hard to remove and may
damage the windows. FUSES
