TIRE ROTATION RECOMMENDATIONS —
SRT
Tires on the front and rear axles of vehicles
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 aggressive tread designs such
as those on all season type tires. Rotation will
increase tread life, help to maintain mud, snow
and wet traction levels, and contribute to a
smooth, quiet ride.
Refer to “Scheduled Servicing” in “Servicing
And Maintenance” for the proper maintenance
intervals. The reasons for any rapid or unusual
wear should be corrected prior to rotation being
performed.
Tire Rotation — Same Tire Size On Front And
Rear Axle
The suggested rotation method for vehicles
equipped with non directional three season and
all season tires is the “forward cross” as shown
in the following diagram.
Tire Rotation (Forward Cross)

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.
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
characteristics 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
performance.

304SERVICING AND MAINTENANCE
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.
VEHICLE STORAGE
If you are leaving your vehicle dormant for more
than 21 days, you may want to take these steps
to protect your battery.
Disconnect the negative cable from the
battery.
Anytime you store your vehicle, or keep it out
of service (e.g., 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 ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
BODYWORK
PROTECTION FROM ATMOSPHERIC
A
GENTS
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.
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.

(Continued)
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.
Special Care
If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercar -
riage 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 respon -
sibility 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.
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.
CAUTION! (Continued)

306SERVICING AND MAINTENANCE
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.
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, 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.
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!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable,
and if used in closed areas they may cause
respiratory harm.
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 sani -
tizers to the plastic, painted, or decorated
surfaces of the interior may cause perma -
nent 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 recom
-
mends 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!
Do not use Alcohol and Alcohol-based and/or
Ketone based cleaning products to clean
leather upholstery, as damage to the
upholstery may result.

IDENTIFICATION DATA
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (VIN) is on
the left front corner of the instrument panel. The
VIN is visible from outside of the vehicle through
the windshield.
Windshield VIN Location

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM

Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems
loses normal capability, the remaining system will
still function. There will be some loss of overall
braking effectiveness. This may be evident by
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.

In the event power assist is lost for any reason
(for example, repeated brake applications with
the engine OFF), the brakes will still function.
The effort required to brake the vehicle will be
much greater than that required with the power
system operating.
SRT — If Equipped
NOTE:
Your vehicle is equipped with a high perfor -
mance braking system. The brake pads are a
semi-metallic compound, which offer superior
fade resistance for consistent operation. A
compromise to using this type of brake pad is that the brakes may produce more brake dust
and may squeal slightly under certain weather
and operating conditions (i.e., during light brake
applications). These are considered normal
conditions.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly
calibrated torque wrench using a high quality six
sided (hex) deep wall socket.

**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil before
tightening.

Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.

Wheel Mounting Surface

Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway). NOTE:
If in doubt about the correct tightness, have
them checked with a torque wrench by an
authorized dealer or service station.
After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.

REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“Reformulated Gasoline”. Reformulated
gasoline contains oxygenates and are
specifically blended to reduce vehicle
emissions and improve air quality.
The use of reformulated gasoline is
recommended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
MATERIALS ADDED TO FUEL
Besides using unleaded gasoline with the
