The suggested rotation method is the “rearward cross”
shown in the following diagram. This rotation pattern does
not apply to some directional tires that must not be reversed.Tire Rotation Dual Rear Wheels — If Equipped
The tires used on dual wheel assemblies should be matched
for wear to prevent overloading one tire in a set. To check if
tires are even, lay a straight edge across all four tires. The
straight edge should touch all the tires.

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.
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.
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.

• 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.
Tri-Fold Soft Tonneau Cover Care
For cleaning and protecting the vinyl Tri-Fold Tonneau
cover, use Mopar Whitewall & Vinyl Top Cleaner and Mopar
Leather and Vinyl Conditioner/Protectant.
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash your vehicle inthe 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.

Bumper Care
The customer is responsible to clean and maintain the
chrome components of the vehicle. Washing away road
debris and salt using an automotive soap. Bumpers should
be cleaned regularly using mild (neutral Ph) soap and water
to maintain their luster and to prevent corrosion.
Your bumpers are susceptible to deterioration caused by salt,
sodium chloride, magnesium chloride, calcium chloride, etc.,
and other road chemicals used to melt ice or control dust on
dirt roads. Do not use harsh chemicals or a stiff brush. They
can stain or damage the protective coating that helps keep
them from corroding and tarnishing.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.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes, or oven cleaner. These products may
damage the bumper’s protective finish. Such damage is
not covered by the New Vehicle Limited Warranty. Only
car wash soap, Mopar Chrome Cleaner, or equivalent is
recommended.
Avoid products or automatic car washes that use acidic
solutions, strong alkaline additives, or harsh brushes.
Many aftermarket cleaners and automatic car washes
may damage the bumper’s protective finish. Such
damage is not covered by the New Vehicle Limited
Warranty. Only car wash soap, Mopar Chrome Cleaner,
or equivalent is recommended. CAUTION!
