2013 JEEP WRANGLER UNLIMITED ESP

Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications if they are available.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “Reformulated Gasoline.”
Reformulated gasolines contain oxygenates and are specifi-
cally blended to reduce vehicle emissions and improve air
quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components. Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as Ethanol. Fuels blended with oxygenates
may be used in your vehicle.
CAUTION!DO NOT use gasoline containing Methanol or gaso-
line containing more than 10% Ethanol. Use of these
blends may result in starting and driveability prob-
lems, damage critical fuel system components, cause
emissions to exceed the applicable standard, and/or
cause the “Malfunction Indicator Light” to illumi-
nate. Pump labels should clearly communicate if a
fuel contains greater than 10% Ethanol.
Problems that result from using gasoline containing
Methanol or gasoline containing more than 10% Ethanol
are not the responsibility of the manufacturer and may
not be covered under warranty. 5 STARTING AND OPERATING 507

can be used at levels higher than those allowed in the
United States. MMT is prohibited in Federal and Califor-
nia reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to contain
effective detergent additives. Use of additional detergents
or other additives is not needed under normal conditions
and they would result in additional cost. Therefore, you
should not have to add anything to the fuel.
Fuel System Cautions
CAUTION!Follow these guidelines to maintain your vehicle’s
performance:
• The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system. (Continued) CAUTION! (Continued)• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact your authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer.
NOTE: Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
5 STARTING AND OPERATING 509

Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE: Mixing engine coolant (antifreeze) types is not
recommended and can result in cooling system damage.
Drain, flush, and refill as soon as possible to avoid
damage if coolant types are mixed in an emergency.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery tank. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!• The warning words “DO NOT OPEN HOT” on the
cooling system pressure cap are a safety precaution.
Never add engine coolant (antifreeze) when the
engine is overheated. Do not loosen or remove the
cap to cool an overheated engine. Heat causes
pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the
pressure cap while the system is hot or under
pressure.
• Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or en-
gine damage may result.580 MAINTAINING YOUR VEHICLE

• 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 or equivalent on
scratches as soon as possible. Your authorized dealer
has touch up paint to match the color of your vehicle. Wheel And Wheel Trim Care
• All wheels and wheel trim, especially aluminum and
chrome plated wheels, should be cleaned regularly
with a mild soap and water to prevent corrosion.
• To remove heavy soil and/or excessive brake dust, use
MOPAR  Wheel Cleaner or equivalent or select a
non-abrasive, non-acidic cleaner.
CAUTION!Do not use scouring pads, steel wool, a bristle brush,
or metal polishes. Do not use oven cleaner. These
products may damage the wheel’s protective finish.
Avoid automatic car washes that use acidic solutions
or harsh brushes that may damage the wheel’s pro-
tective finish. Only MOPAR  Wheel Cleaner or
equivalent is recommended.

Interior Care
Use MOPAR  Total Clean or equivalent to clean fabric
upholstery and carpeting.
Interior Trim should be cleaned starting with a damp
cloth, a damp cloth with MOPAR  Total Clean or equiva-
lent , then MOPAR  Spot & Stain Remover or equivalent
if absolutely necessary. Do not use harsh cleaners or
Armor All  . Use MOPAR  Total Clean or equivalent to
clean vinyl upholstery.
WARNING!Do not use volatile solvents for cleaning purposes.
Many are potentially flammable and, if used in
closed areas, they may cause respiratory harm. CAUTION!When installing hanging air fresheners in your ve-
hicle, read the installation instructions carefully.
Some air fresheners will damage the finish of
painted or decorated parts if allowed to directly
contact any surface.
Glass Surfaces
All glass surfaces should be cleaned on a regular basis
with MOPAR  Glass Cleaner or equivalent, or any com-
mercial household-type glass cleaner. Never use an abra-
sive type cleaner. Use caution when cleaning the inside
rear window equipped with electric defrosters or the
right rear quarter window equipped with the radio
antenna. Do not use scrapers or other sharp instrument
that may scratch the elements.594 MAINTAINING YOUR VEHICLE

• 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 Win-
dows.”
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  Con-
vertible 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!Failure to follow these cautions may cause interior
water damage, stains or mildew on the top material:
• Avoid high-pressure car washes, as they can dam-
age the top material. Also, increased water pressure
may force past the weather strips.
• 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. (Continued)596 MAINTAINING YOUR VEHICLE

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.
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.
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 car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades B and A repre-
sent higher levels of performance on the laboratory test
wheel, than the minimum required by law.
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 load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.632 IF YOU NEED CONSUMER ASSISTANCE
