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 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 the “Maintenance Plan” for the proper
maintenance intervals. The reasons for any
rapid or unusual wear should be corrected prior
to rotation being performed.
The suggested rotation method is the “forward
cross” shown in the following diagram. This
rotation pattern does not apply to some direc -
tional tires that must not be reversed. 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.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km). Autosock traction devices do not
require retightening.
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns and
large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device manufacturer’s
instructions on the method of installation,
operating speed, and conditions for use.
Always use the suggested operating speed
of the device manufacturer’s if it is less
than 30 mph (48 km/h).
Do not use traction devices on a compact
spare tire.
CAUTION!

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 char -
acteristics 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 spec -
ified government test surfaces of asphalt and
concrete. A tire marked C may have poor trac -
tion performance.
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 the
battery.
Any time 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 prior to storing. This will
ensure adequate system lubrication to mini -
mize 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 corro -
sive 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 suscep-
tible 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 mate
-
rial 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.

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.
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 uphol-
stery 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 protectants on Stain Repel products.
Use of power washers exceeding 1,200 psi
(8,274 kPa) can result in damage or
removal of paint and decals.
CAUTION!

Seat Belt Maintenance
Do not bleach, dye or clean the belts with chem -
ical 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 solu -
tion 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.

tion 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 sani -
tizers to the plastic, painted, or decorated
surfaces of the interior may cause perma -
nent damage. Wipe away immediately.

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. Stub -
born 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 condi -
tion.
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.
Cleaning The Instrument Panel Cupholders
Removal
Pull the flexible liner from the cupholder drawer
starting at one edge to ease removal.
Cleaning
The liner is top shelf dishwasher safe, or you
may follow the cleaning procedure below.
Soak the liner in a mixture of medium hot tap
water and one teaspoon of mild liquid dish
soap. Let soak for approximately 30 minutes.
After 30 minutes, pull the liner from the water
and dip it back into the water about six times.
This will loosen any remaining debris. Rinse the
liner thoroughly under warm running water.
Shake the excess water from the liner and dry
the outer surfaces with a clean soft cloth.
Installation
Place the liner into the cupholder drawer and
push the liner into place so that the retention
tabs seat into the corresponding openings in
the drawer.
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.

TECHNICAL SPECIFICATIONS
IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found
on the left front corner of the instrument panel,
visible through the windshield. This number
also appears on the vehicle frame and under-
body as well as the Automobile Information
Disclosure Label affixed to a window on your
vehicle, the vehicle registration and title.
Vehicle Identification Number 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. However, there will be
some loss of overall braking effectiveness. You
may notice increased pedal travel during appli
-
cation, greater pedal force required to slow or
stop, and potential activation of the “Brake
System Warning Light”.
In the event power assist is lost for any reason
(i.e., repeated brake applications with the
engine off), the brakes will still function.
However, the effort required to brake the
vehicle will be much greater than that required
with the power system operating.
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 cali -
brated torque wrench using a high quality six
sided (hex) deep wall socket.

torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and perfor-
mance when using high quality
unleaded “Regular” gasoline having a posted
octane number of 87 as specified by the (R+M)/
2 method. The use of higher octane “Premium”
gasoline is not required, as it will not provide
any benefit over “Regular” gasoline in these
engines. While operating on gasoline with an octane
number of 87, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see your dealer immediately.
Use of gasoline with an octane number lower
than 87 can cause engine failure and may void
or not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Refor
-
mulated Gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom -
mended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.
