Tire Safety Information
Tire safety information will cover aspects of
the following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures and Tire Loading.
Tire Markings
NOTE:
• P (Passenger) — Metric tire sizing isbased on U.S. design standards. P-Metric
tires have the letter “P” molded into the
sidewall preceding the size designation.
Example: P215/65R15 95H. • European — Metric tire sizing is based on
European design standards. Tires de-
signed to this standard have the tire size
molded into the sidewall beginning with
the section width. The letter "P" is absent
from this tire size designation. Example:
215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S. design standards. The size
designation for LT-Metric tires is the same
as for P-Metric tires except for the letters
“LT” that are molded into the sidewall
preceding the size designation. Example:
LT235/85R16.
• Temporary spare tires are designed for temporary emergency use only. Temporary
high pressure compact spare tires have
the letter “T” or “S” molded into the
sidewall preceding the size designation.
Example: T145/80D18 103M.
• High flotation tire sizing is based on U.S. design standards and it begins with the
tire diameter molded into the sidewall.
Example: 31x10.5 R15 LT.

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 dissi-
pate heat, when tested under controlled con-
ditions 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 corre-
sponds 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 temperature grade for this tire is es-
tablished for a tire that is properly inflated
and not overloaded. Excessive speed,
under-inflation, or excessive loading, ei-
ther separately or in combination, can
cause heat buildup and possible tire fail-
ure.
STORING THE VEHICLE
If the vehicle should remain stationary for
more than a month, observe the following
precautions:
• Park your vehicle in a covered, dry andpossibly airy location the windows open
slightly.
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery post and be sure that the
battery is fully charged. During storage
check battery charge quarterly. • If you do not disconnect the battery from
the electrical system, check the battery
charge every thirty days.
• Clean and protect the painted parts by applying protective waxes.
• Clean and protect polished metal parts by applying protective waxes.
• Apply talcum powder to the front and rear wiper blades and leave raised from the
glass.
• Cover the vehicle with an appropriate cover taking care not to damage the
painted surface by dragging across dirty
surfaces. Do not use plastic sheeting
which will not allow the evaporation of
moisture present on the surface of the
vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar) higher than recommended on
the tire placard and check it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is station- ary for two weeks or more, run idle the
engine for approximately five minutes,
with the air conditioning system on and
high fan speed. This will ensure a proper
267

lubrication of the system, thus minimizing
the possibility of damage to the compres-
sor when the vehicle is put back into
operation.
NOTE:
When the vehicle has not been started or
driven for at least 30 days, an Extended Park
Start Procedure is required to start the ve-
hicle. Refer to “Starting Procedures” in
“Starting And Operating” for further
information.
CAUTION!
Before removal of the positive and nega-
tive terminals to the battery, wait at least a
minute with ignition switch in the OFF
position and close the drivers door. When
reconnecting the positive and negative ter-
minals to the battery be sure the ignition
switch is in the OFF position and the
drivers door is closed.
BODYWORK
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic head-
lights 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 wip-
ing 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.

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.
Leather Parts
MOPAR Total Clean is specifically recom-
mended 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, sol- vents, detergents, or ammonia-based clean-
ers to clean your leather upholstery. Applica-
tion 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 col-
ors. The leather is designed to for easy clean-
ing, and FCA recommends MOPAR total care
leather cleaner applied on a cloth to clean the
leather seats as needed.
CAUTION!
Do not use Alcohol and Alcohol-based
and/or Keton based cleaning products to

meet all emissions regula-
tions and provide excel-
lent fuel economy and
performance when using
high-quality unleaded
“Regular” gasoline having
an octane rating of 87 as specified by the
(R+M)/2 method. The use of higher octane
“Premium” gasoline will not provide any ben-
efit 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 imme-
diately. Use of gasoline with an octane num-
ber lower than 87 can cause engine failure
and may void or not be covered by the New
Vehicle Limited Warranty.

ket and diaphragm materials.
FUEL REQUIREMENTS –
DIESEL ENGINE
Use good quality diesel fuel from a reputable
supplier in your vehicle. Federal law requires
that you must fuel this vehicle with Ultra Low
Sulfur Highway Diesel fuel (15 ppm Sulfur
maximum) and prohibits the use of Low Sul-
fur Highway Diesel fuel (500 ppm Sulfur
maximum) to avoid damage to the emissions
control system.
For most year-round service, No. 2 diesel fuel
meeting ASTM (formerly known as the Ameri-
can Society for Testing and Materials) speci-
fication D-975 Grade S15 will provide good
performance. If the vehicle is exposed to
extreme cold (below 20°F or -7°C), or is
required to operate at colder-than-normal
conditions for prolonged periods, use clima-
tized No. 2 diesel fuel or dilute the No.
2 diesel fuel with 50% No. 1 diesel fuel. This
will provide better protection from fuel gell-
ing or wax-plugging of the fuel filters.
WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and hazardous or
explosive when mixed with diesel fuel.
Diesel fuel is seldom completely free of wa-
ter. To prevent fuel system trouble, drain the
accumulated water from the fuel/water sepa-
rator using the fuel/water separator drain pro-
vided on the fuel filter housing. If you buy
good quality fuel and follow the cold weather
advice above, fuel conditioners should not be
required in your vehicle. If available in your
area, a high cetane “premium” diesel fuel
may offer improved cold-starting and
warm-up performance.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filter(s) to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Servicing
And Maintenance” for further information.
Diesel Fuel Specifications
This diesel engine has been developed to
take advantage of the high energy content
and generally lower cost No. 2 Ultra Low
Sulfur diesel fuel or No. 2 Ultra Low Sulfur
climatized diesel fuels.
NOTE:
• If you accidentally fill the fuel tank with gasoline on your diesel vehicle, do not
start the engine. Damage to the engine
and fuel system could occur. Please call
your authorized dealer for service.
• A maximum blend of 5% biodiesel meet- ing ASTM specification D-975 may be
used with your diesel engine without any
adjustments to regular service schedules.
• Commercially available fuel additives are not necessary for the proper operation of
your diesel engine.
• No. 1 Ultra Low Sulfur diesel fuel should only be used where extended arctic condi-
tions (-10°F or -23°C) exist.
