TIRE ROTATION RECOMMENDATIONS
The tires on the front and rear of your vehicle
operate at different loads and perform different
steering, handling, 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 On/Off Road type tires. Rotation will
increase tread life, help to maintain mud, snow,
and wet traction levels, and contribute to a
smooth, quiet ride. For the proper maintenance intervals
Úpage 354.
The reasons for any rapid or unusual wear should
be corrected prior to rotation being performed.
The suggested rotation method is the “rearward
cross” shown in the following diagram.

Tire Rotation (Rearward Cross)

WARNING!
Using tires of different size and type (M+S,
Snow) between front and rear axles can cause
unpredictable handling. You could lose control
and have a collision.
CAUTION!
To avoid damage to your vehicle or tires, observe
the following precautions:
Because of restricted traction device clear -
ance between tires and other suspension
components, it is important that only traction
devices in good condition are used. Broken
devices can cause serious damage. Stop the
vehicle immediately if noise occurs that could
indicate device breakage. Remove the
damaged parts of the device before further
use.
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!
CAUTION!
Proper operation of four-wheel drive vehicles
depends on tires of equal size, type, and
circumference on each wheel. Any difference in
tire size can cause damage to the transfer case.
Tire rotation schedule should be followed to
balance tire wear.8

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.
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.WARNING!
The temperature grade for this tire is estab
-
lished for a tire that is properly inflated and not
overloaded. Excessive speed, under-inflation, or
excessive loading, either separately or in combi -
nation, can cause heat build-up and possible tire
failure.

STORING THE VEHICLE If you are storing your vehicle for more than 3
weeks, we recommend that you take the following
steps to minimize the drain on your vehicle's
battery:
Disconnect the negative cable from the battery.
If your vehicle is equipped with Stop/Start
system then disconnect both the main and
supplemental negative battery cables.
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. This will ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
If assistance is needed to disconnect the
battery system, see an authorized dealer.

Battery Cable Disconnect

NOTE:
You must isolate the supplemental battery
connection point, as well as the main battery
terminal from the post, as shown in the image,
to fully de-energize both batteries for storage. If

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 in the shade using Mopar® Car Wash, or
a mild car wash soap, and rinse the panels
completely with 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 and stains,
and to protect your paint finish. Use precautions
to not 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.
If your vehicle is damaged due to a collision or
similar cause that destroys the paint and protec
-
tive coating, have your vehicle repaired as soon
as possible.
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.
CAUTION!
Do not use abrasive or strong cleaning mate -
rials, 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!

Appearance Care For Fabric Top Models
To maintain the appearance of your vehicle's
interior trim and top, follow these precautions:
Do not run a fabric top through an automatic car
wash. Window scratches and wax build-up may
result.
Avoid leaving your vehicle unattended with the
top down, as exposure to sun or rain may
damage interior trim.
Do not use harsh cleaners or bleaching agents
on top material, as damage may result.
Do not allow any vinyl cleaner to run down and
dry on the paint, leaving a streak.
After cleaning your vehicle's fabric top, always
make sure it is completely dry before lowering.
Be especially careful when washing the
windows by following the directions for “Care of
Fabric Top Windows.”
Washing – Use Mopar® Car Wash or equivalent, or
mild soap suds, lukewarm water, and a brush with
soft bristles. If extra cleaning is required, use
Mopar® Convertible Cloth Top Cleaner or
equivalent, or a mild foaming cleaner on the entire
top, but support the top from underneath.
Rinsing – Be sure to remove all traces of cleaner by
rinsing the top thoroughly with clean water.
Remember to allow the top to dry before
lowering it.Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic
windows that can be scratched unless special care
is taken by following these directions:
Never use a dry cloth to remove dust. Instead,
use a microfiber towel or soft cotton cloth moist -
ened with cold or warm, clean water, and wipe
across the window, not up and down. Mopar®
Jeep® Soft Glass Window Cleaner or equivalent
will safely clean all the plastic windows without
scratching. It removes fine scratches to improve
visibility and provides UV protection to help
prevent yellowing.
CAUTION!
Failure to follow these cautions may cause
interior water damage, stains, or mildew of the
top material:
Do not run a fabric top through an automatic
car wash. Window scratches and wax build-up
may result.
It is recommended that the top be free of
water prior to opening it. Operating the top,
opening a door or lowering a window while the
top is wet may allow water to drip into the
vehicle’s interior.
Use care when washing the vehicle, water
pressure directed at the weather strip seals
may cause water to leak into the vehicle’s
interior.
Careless handling and storage of the remov -
able roof panels may damage the seals,
causing water to leak into the vehicle’s inte -
rior.
The front panel(s) must be positioned properly
to ensure sealing. Improper installation can
cause water to leak into the vehicle’s interior.
Avoid (if at all possible) parking the vehicle
under trees; remove vegetable resins immedi -
ately as, when dried, it may only be possible to
remove them with abrasive products and/or
polishes, which is highly inadvisable as they
could alter the typical opaqueness of the
paint.
Do not use pure windshield washer fluid for
cleaning the front windshield and rear
window; dilute it to a minimum of 50% water.
Only use pure windshield washer fluid when
strictly necessary due to outside temperature
conditions.
CAUTION!

(Continued)
When washing, never use hot water or anything
stronger than a mild soap. Never use solvents
such as alcohol or harsh cleaning agents.
Always rinse thoroughly with cold water, then
wipe with a soft and slightly moist, clean cloth.
When removing frost, snow, or ice, never use a
scraper or de-icing chemicals. Use warm water
only if you must clean the window quickly.
Debris (sand, mud/dirt, dust, or salt) from
off-road driving will have an impact on plastic
retainer operation. Even normal on-road driving
and vehicle washing will eventually impact
window plastic retainer operation. To maintain
ease of use of the window plastic retainers,
each window plastic retainer should be cleaned
and lubricated regularly. Clean them with a mild
soap solution and a small brush. Cleaning prod -
ucts are available through an authorized dealer.
Never paste stickers, gummed labels or any
tape to the windows. Adhesives are hard to
remove and may damage the windows.
INTERIORS
CARPET SAFETY INFORMATION
Always use carpet designed to fit your vehicle. Only
use carpet that does not interfere with the
operation of the pedal assemblies. Only operate
the vehicle when the carpet is securely attached by
the grommets so it cannot slip out of position and
interfere with the pedal assemblies or impair safe
operation of your vehicle in other ways.
WARNING!
If operating the vehicle without carpet in place
the floor may become hot, and there is a risk
of burns.
An improperly attached, damaged, folded, or
damaged grommets may cause your carpet to
interfere with the accelerator, brake, or clutch
pedals and cause a loss of vehicle control. To
prevent SERIOUS INJURY or DEATH: ALWAYS
securely attach your carpet using the grom -
mets.
ALWAYS make sure objects cannot fall or slide
into the driver’s side floor area when the
vehicle is moving. Objects can become
trapped under accelerator, brake, or clutch
pedals and could cause a loss of vehicle
control.
NEVER place any objects under the carpet
(e.g., towels, keys, etc.). These objects could
change the position of the carpet and may
cause interference with the accelerator,
brake, or clutch pedals.
ONLY install carpet designed to fit your
vehicle. NEVER install carpet that cannot be
properly attached and secured to your vehicle.
If the carpet needs to be replaced, only use
manufacturer approved carpet for the specific
make, model, and year of your vehicle.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check that the floor mat
fasteners are secure to the vehicle carpet.

may be used, but do not use high alcohol content
or abrasive cleaners. If soap is used, wipe clean
with a clean damp cloth. Dry with a soft cloth.
LEATHER SURFACES
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.

show any foreign material, dirt, and fabric dye
transfer more so than darker colors. The leather is
designed for easy cleaning, and the manufacturer
recommends Mopar® Total Clean 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 rearview mirror, spray cleaner
on the towel or cloth that you are using. Do not
spray cleaner directly on the mirror.
CAUTION!
Direct contact of air fresheners, insect repel -
lents, suntan lotions, or hand sanitizers to the

the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN plate.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
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 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 (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 calibrated
torque wrench using a six-sided (hex) deep wall
socket.
