2004 JEEP WRANGLER Owners Manual

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:
²Road salt, dirt and moisture accumulation.
²Stone and gravel impact.
²Insects, tree sap and tar.
²Salt in the air near sea-coast localities.
²Atmospheric fallout/industrial pollutants.
²Bird droppings.
Washing
²
Wash your vehicle regularly. Always wash your ve-
hicle in the shade using a mild car wash soap and rinse
the panels completely with clear water.
²If insects, tar, or other similar deposits have accumu-
lated on your vehicle, wash it as soon as possible.
²Use MopartAuto Polish to remove road film and
stains and to polish your vehicle. Take care never to
scratch the paint.
²Avoid 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, which will
scratch metal and painted surfaces.

Appearance Care For Fabric Top Models
CAUTION!
To maintain the appearance of your vehicle's interior
trim and top, follow these precautions:
²Avoid leaving your vehicle unattended with the top
down, as exposure to sun or rain may damage interior
trim.
²Do not use harsh cleaners or bleaching agents on top
material, as damage may result.
²Do not allow any vinyl cleaner to run down and dry
on the paint, leaving a streak.
²After cleaning your vehicle's fabric top, always make
sure it is completely dry before lowering.
²Be especially careful when washing the windows by
following the directions for ªCare of Fabric Top Win-
dows.ºWASHING ÐAlways use mild soap suds, lukewarm
water, and a brush with soft bristles. If extra cleaning is
required, use a mild foaming cleaner on the entire top,
but support top from underneath.
RINSING ÐBe sure to remove all trace of cleaner by
rinsing the top thoroughly with clean water. Remember
to allow the top to dry before lowering it.
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
soft cotton cloth moistened with cold or warm, clean
water, and wipe across the window, not up and down.
2. When washing,never use hot wateror anything
stronger than a mild soap. Never use solvents such as
alcohol or harsh cleaning agents.
250 MAINTAINING YOUR VEHICLE

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 regularly. Use Mopart
Soft Top Zipper Cleaner and Lubricant 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 MopartSoft Top Zipper Cleaner and Lubricant
into the zipper teeth. If a stuck zipper slide is experi-
enced, work the MopartSoft Top Zipper Cleaner and
Lubricant 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 dam-
age the windows.
Special Care
²
If you drive on salted or dusty roads or if you drive
near the ocean, hose off the undercarriage at least once
a month.
²It is important that the drain holes in the lower edges
of the doors, rocker panels and tailgate must be kept
clear and open.
²If 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.
²If you carry special cargo such as chemicals, fertilizers,
de-icer salt, etc., assure that such materials are well
packaged and sealed.
²If a lot of driving is done on gravel roads, consider
mud or stone shields behind each wheel.

²Use MopartTouch Up Paint on scratches or chips as
soon as possible. Your authorized dealer has touch up
paint to match the color of your vehicle.
²Aluminum wheels should be cleaned regularly with
mild soap and water to prevent corrosion. To remove
heavy soil, select a non-abrasive, non-acidic cleaner.
Do not use scouring pads or metal polishes. Avoid
automatic car washes that use acidic solutions or harsh
brushes that may damage the wheels' protective fin-
ish.
Interior Care
Use MopartFabric Cleaner to clean fabric upholstery
and carpeting.
Use MopartVinyl Cleaner to clean vinyl or leather
upholstery.
MopartVinyl Cleaner is specifically recommended for
interior vinyl trim.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas they may cause respiratory harm.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with any commercial household-type glass cleaner.
Never use an abrasive type cleaner. Use caution when
cleaning inside rear windows equipped with electric
defrosters. Do not use scrapers or other sharp instru-
ments 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.
Carpet
Vacuum your carpet regularly to prevent a soil build-up.
Shampoo soiled carpet with a reliable upholstery cleaner,
using a natural sponge or soft bristle brush. After carpet
dries, vacuum it thoroughly.
252 MAINTAINING YOUR VEHICLE

WARNING!
Only remove the carpet for cleaning purposes. It
provides insulation against high floor pan tempera-
tures. You or your passengers could be burned if the
carpet is not properly in place. Always put the carpet
back into the vehicle before driving.
Follow These Steps To Remove The Carpet:
1. Unsnap the front and rear floor carpets. A snap is
located on the outboard side of each front seat.
2. Remove the attachment cap from the front footwell
area on both the driver and passenger side. The cap is
removed by pulling it straight out.
3. Remove the front and rear floor carpets.
4. Remove the cargo floor and wheelhouse carpets.
NOTE:If your vehicle is equipped with an Add-A-
TrunkŸ it must be removed to be able to remove the cargo
floor and wheelhouse carpets. For Add-A-TrunkŸ removal
procedure, refer to ªStorageº in Section 3 of this manual.
Follow These Steps To Replace The Carpet:
1. Place the front floor carpets in the vehicle.
2. Attach the carpet to the studs in the footwell and press
on the attachment caps to secure the carpet.
3. Place rear floor carpet in vehicle and snap rear carpet
to front floor carpet.
4. Install wheelhouse carpet followed by the cargo floor
carpet.
5. Reinstall Add-A-TrunkŸ if so equipped.
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 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.

Maintenance After Off-Road Driving
After extended operation in mud, sand or water, or
similar dirty conditions, have your brake drums, brake
linings, and axle joints inspected and cleaned as soon as
possible. This will prevent any abrasive material from
causing excessive wear or unpredictable braking action.
Following off-road usage, completely inspect the under-
body of your vehicle. Check tires, body structure, steer-
ing, suspension and exhaust system for damage. Check
threaded fasteners for looseness, particularly on the
chassis, drivetrain components, steering and suspension.
Retighten, if required, to torque values specified in the
Service Manual. Also check for accumulations of vegeta-
tion or brush that could become a fire hazard, or conceal
damage to fuel lines, brake hoses, axle pinion seals, and
propeller shafts. Check air conditioning drain tube on the
lower dash wall in the engine compartment for mud or
debris, and clean as required. A plugged tube will
adversely affect air conditioning performance.CAUTION!
Under frequent heavy-duty driving conditions,
change all lubricants, and lubricate body compo-
nents and steering linkage more often than in nor-
mal service to prevent excessive wear.
FUSE PANEL
Interior Fuses
The fuse panel is located behind the glove box.
254 MAINTAINING YOUR VEHICLE

To access the fuse panel the glove box must be removed.
It is removed by slipping the glove box strap off the hook
and letting the door roll down off its hinges. To reinstall,
position the glove box door at an 8 o'clock orientation,
engage the hinge hook formations on the lower edge of
the glove box door with the hinge pins on the lower edge
of the instrument panel. Tilt the upper edge of the glove
box door upward toward the instrument panel enough to
reattach the glove box strap to the door. Rotate glove box
door to closed position. Open and close to insure proper
installation.

Underhood Fuses (Power Distribution Center)
Your vehicle is equipped with an electrical power distri-
bution center located in the engine compartment near the
battery. This power center houses plug-in ªCartridgeº
fuses, ISO relays, and Mini (Micro) fuses.
A label inside the latching cover of the center identifies
each component for ease of replacement, if necessary.
Cartridge and mini (micro) fuses can be obtained from
your authorized dealer.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
²Remove Cartridge fuse #15 in the Power Distribution
Center labeled Ignition-Off Draw (IOD).
²Store the removed IOD fuse in the Power Distribution
Center location #11 labeled ªIOD Storage.º
²Or, disconnect the negative cable from the battery.
²Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
