468 SERVICING AND MAINTENANCE
(Continued)NOTE:
If your vehicle is equipped with a Tire Pressure Information
System (TPIS):
• The Tire Pressure Information System (TPIS) uses unique
sensors in the inner rear wheels to help identify them from
the outer rear wheels, because of this, the inner and outer
wheel locations can’t be switched.
• After a tire rotation is completed, as shown below, the
system can auto learn the locations of each sensor ID. Auto
learning/localization occurs when the vehicle ignition
status is changed from Off to On and speeds of greater
than 5 mph (8km/h) are obtained and remain over 5mph
(8km/h) for at about a 15 minute period. You may need to
drive for 20 minutes to account slower speeds and stops.
• If the tires are rotated incorrectly, the Auto localization of
the TPIS sensors will fail to locate correctly resulting in
incorrect locations for the pressure values displayed in the
Instrument Cluster. DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by
the National Highway Traffic Safety Administration. The
specific grade rating assigned by the tire's manufacturer
in each category is shown on the sidewall of the tires on
your vehicle.
All passenger vehicle tires must conform to Federal safety
requirements in addition to these grades.CAUTION!
• 4500/5500 Dual Rear Tires may only have one approved
direction of rotation. This is to accommodate the asym -
metrical design (tread pattern) of the On/Off road tire. • When replacing a flat, the spare tire may have to be
remounted on the rim or installed at a different location
to maintain the correct placement of the tire on the
wheel relative to the tire/wheel position on the vehicle.
For example, if the spare is used to replace an outer rear
tire it will have to be remounted on the rim so that the
wheel is dished inward. That way the tread design of
asymmetrical tires will maintain proper position. CAUTION! (Continued)

SERVICING AND MAINTENANCE 469
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac -
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A, B,
and C. These grades represent the tire's ability to stop on
wet pavement, as measured under controlled conditions
on specified government test surfaces of asphalt and
concrete. A tire marked C may have poor traction perfor -
mance. Temperature Grades
The Temperature grades are A (the highest), B, and C,
representing the tire's resistance to the generation of heat
and its ability to dissipate heat, when tested under
controlled conditions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the material of the
tire to degenerate and reduce tire life, and excessive
temperature can lead to sudden tire failure. The grade C
corresponds to a level of performance, which all
passenger vehicle tires must meet under the Federal
Motor Vehicle Safety Standard No. 109. Grades B and A
represent higher levels of performance on the laboratory
test wheel, than the minimum required by law. WARNING!
The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not
include acceleration, cornering, hydroplaning, or peak
traction characteristics.

STORING THE VEHICLE
If you are storing your vehicle for more than 21 days, we
recommend that you take the following steps to minimize
the drain on your vehicle's battery:
• Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it out of service
(i.e., vacation) for two weeks or more, run the air condi -
tioning system at idle for about five minutes in the fresh air
and high blower setting. This will ensure adequate system
lubrication to minimize the possibility of compressor
damage when the system is started again. BODYWORK
Protection From Atmospheric Agents
Vehicle body care requirements vary according to
geographic 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 underbody protection.
The following maintenance recommendations will enable
you to obtain maximum benefit from the corrosion resistance
built into your vehicle.WARNING!
The temperature grade for this tire is established for a
tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.

SERVICING AND MAINTENANCE 471
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.
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic headlights and fog
lights that are lighter and less susceptible to stone breakage
than glass headlights.
Plastic is not as scratch resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution followed
by rinsing. Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash your vehicle in
the shade using Mopar Car Wash, or a mild car wash soap,
and rinse the panels completely with clear water.
• If insects, tar, or other similar deposits have accumulated
on your vehicle, use Mopar Super Kleen Bug and Tar
Remover to remove.
• Use a high quality cleaner wax, such as Mopar Cleaner
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.
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. 7

472 SERVICING AND MAINTENANCE
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.
• 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 pack -
aged 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 on scratches as soon as
possible. An authorized dealer has touch up paint to
match the color of your vehicle. INTERIORS
Seats And Fabric Parts
Use Mopar Total Clean to clean fabric upholstery and carpeting.
Stain Repel Fabric Cleaning Procedure — If Equipped
Stain Repel seats may be cleaned in the following manner:
• Remove as much of the stain as possible by blotting with a
clean, dry towel.
• Blot any remaining stain with a clean, damp towel.
• 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

are potentially flammable, and if used in closed areas
they may cause respiratory harm.

SERVICING AND MAINTENANCE 473
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 luke -
warm 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.
NOTE:
If the belts retract slowly, inspect the upper turning loop for
soiling. If soiling is present, clean with a wet soft cloth until
all residue is removed. Plastic And Coated Parts
Use Mopar Total Clean to clean vinyl upholstery.
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 cloth. 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
cloth.
2. Dry with a soft cloth.WARNING!
A frayed or torn belt could rip apart in a collision and
leave you with no protection. Inspect the belt system
periodically, checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately. Do not
disassemble or modify the system. Seat belt assemblies
must be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing, etc.). CAUTION!
• Direct contact of air fresheners, insect repellents,
suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may cause
permanent damage. Wipe away immediately.
• Damage caused by these type of products may not be
covered by your New Vehicle Limited Warranty.

Leather Parts
Mopar Total Clean is specifically recommended 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. Care should be taken to avoid soaking your leather
upholstery with any liquid. Please do not use polishes, oils,
cleaning fluids, solvents, detergents, or ammonia-based
cleaners to clean your leather upholstery. Application of a
leather conditioner is not required to maintain the original
condition.
NOTE:
If equipped with light colored leather, it tends to show any
foreign material, dirt, and fabric dye transfer more so than
darker colors. The leather is designed for easy cleaning, and
FCA recommends Mopar total care leather cleaner applied
on a cloth to clean the leather seats as needed. 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 windows equipped with radio
antennas. Do not use scrapers or other sharp instruments
that may scratch the elements.
When cleaning the rear view mirror, spray cleaner on the
towel or cloth that you are using. Do not spray cleaner
directly on the mirror. CAUTION!
