286 SERVICING AND MAINTENANCE
Your wheels 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. Use a soft cloth or sponge and mild soap to wipe
away promptly. Do not use harsh chemicals or a stiff brush.
They can damage the wheel’s protective coating that helps
keep them from corroding and tarnishing.
When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent damage
to the wheels. Mopar Wheel Treatment or Mopar Chrome
Cleaner or their equivalent is recommended or select a
non-abrasive, non-acidic cleaner for aluminum or chrome
wheels.NOTE:
If you intend parking or storing your vehicle for an extended
period after cleaning the wheels with wheel cleaner, drive
your vehicle and apply the brakes to remove the water drop
-
lets from the brake components. This activity will remove the
red rust on the brake rotors and prevent vehicle vibration
when braking.
CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
Many aftermarket wheel cleaners and automatic car
washes may damage the wheel's protective finish. Such
damage is not covered by the New Vehicle Limited
Warranty. Only car wash soap, Mopar Wheel Cleaner or
equivalent is recommended.CAUTION!
Do not use scouring pads, steel wool, a bristle brush,
metal polishes or oven cleaner. These products may
damage the wheel's protective finish. Such damage is not
covered by the New Vehicle Limited Warranty. Only car
wash soap, Mopar Wheel Cleaner or equivalent is
recommended.

Tire Chains (Traction Devices)
Due to limited clearance, tire chains or traction devices are
not recommended.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle operate at
different loads and perform different steering, driving, and
braking functions. For these reasons, they wear at unequal
rates.
These effects can be reduced by timely rotation of tires. The
benefits of rotation are especially worthwhile with aggres-
sive tread designs such as those on all season type tires. Rota -
tion will increase tread life, help to maintain mud, snow and
wet traction levels, and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the proper maintenance
intervals. The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
CAUTION!
If your vehicle is equipped with these specialty wheels,
DO NOT USE wheel cleaners, abrasives, or polishing
compounds. They will permanently damage this finish
and such damage is not covered by the New Vehicle
Limited Warranty. HAND WASH ONLY USING MILD
SOAP AND WATER WITH A SOFT CLOTH. Used on a
regular basis; this is all that is required to maintain this
finish.
CAUTION!
Damage to the vehicle may result if tire chains are used.

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.
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.

SERVICING AND MAINTENANCE 289
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.
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.
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.
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.

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• 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 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. 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.
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.
