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.
STORING THE 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, underinflation, or excessive loading,
either separately or in combination, can cause heat
buildup and possible tire failure.
WARNING!

Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be injured by moving fan
blades.
 Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
 Vehicles with the Stop/Start system will be equipped
with two batteries. Both the main and the supple -
mental batteries must be disconnected to
completely de-energize the 12 Volt electrical system.
 Serious injury or death could result if you do not
disconnect both batteries. To learn how to properly
disconnect, see an authorized dealer.

360SERVICING AND MAINTENANCE
If you are storing your vehicle for more than three weeks,
we recommend that you take the following steps to
minimize the drain on your vehicle's battery:
Disconnect the negative cable from 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 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.
 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 assistance is needed to discon -
nect the battery system, see an authorized dealer.
 Do not disconnect the Intelligent Battery Sensor (IBS),
or your Stop/Start system may not function for up to 24
hours, due to the IBS being set into learn mode.
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.
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.
CAUTION!
If the negative battery cables are not isolated properly it
can cause a potential power spike or surge in the
system, resulting in damage to essential electrical
components.

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 accumu -
lated 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. 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. 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
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.
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.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.

Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic windows which
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 moistened 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
plastic windows without scratching. It removes fine
scratches to improve visibility and provides UV protec -
tion to help prevent yellowing.
 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 opera -
tion. Even normal on-road driving and vehicle washing
will eventually impact window plastic retainer opera -
tion. 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.
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 removable roof
panels may damage the seals, causing water to leak
into the vehicle’s interior.
 The front panel(s) must be positioned properly to
ensure sealing. Improper installation can cause
water to leak into the vehicle’s interior.
CAUTION!
Avoid washing with rollers and/or brushes in washing
stations. Wash the vehicle only by hand using neutral
pH detergents; dry it with a wet chamois leather.
Abrasive products and/or polishes should not be
used for cleaning the car.
Bird droppings must be washed off immediately and
thoroughly as the acid they contain is particularly
aggressive.
 Avoid (if at all possible) parking the vehicle under
trees; remove vegetable resins immediately 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 opaque -
ness 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!
