SEATS AND FABRIC PARTS
Use Mopar® Total Clean to clean fabric upholstery
and carpeting.
Seat Belt Maintenance
If the belts need cleaning, use a mild soap solution
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.
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!
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This will
weaken the fabric. Sun damage can also
weaken the fabric
WARNING!
A frayed or torn seat belt could rip apart in a
collision and leave you with no protection.
Inspect the seat belt system periodically,
checking for cuts, frays, or loose parts.
Damaged parts must be replaced immediately.
Do not disassemble or modify the seat belt
system. If your vehicle is involved in a collision,
or if you have questions regarding seat belt or
retractor conditions, take your vehicle to an
authorized FCA dealer or authorized FCA
Certified Collision Care Program facility for
inspection.

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.
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. 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.
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 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
plastic, painted, or decorated surfaces of the
interior may cause permanent damage. Wipe
away immediately.
Damage caused by these type of products
may not be covered by your New Vehicle
Limited Warranty.
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.

422TECHNICAL SPECIFICATIONS
BIODIESEL FUEL REQUIREMENTS
A maximum blend of 5% biodiesel meeting ASTM
specification D975 is recommended for use with
your diesel engine. If frequent operation with
biodiesel blends that are between 6% and 20%
(B6–B20) is desired, the maintenance schedule is
subject to shorter intervals.
The oil and filter change along with fuel filter
replacement is subject to shorter intervals when
operating your engine on biodiesel greater than
5%. Do not use biodiesel greater than 20%.
For regular use of biodiesel blends between 6%
and 20% (B6–B20) it is important that you
understand and comply with these requirements
Úpage 358.
Biodiesel is a fuel produced from renewable
resources typically derived from animal fat,
rapeseed oil (Rapeseed Methyl Ester (RME) base),
or soybean oil (Soy Methyl Ester (SME or SOME)
base). Biodiesel fuel has inherent limitations which
require that you understand and adhere to the
following requirements if you use blends of
biodiesel between 6% and 20% (B6–B20). There
are no unique restrictions for the use of B5.
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for both
storage and operation. Precautions can be
necessary at low ambient temperatures, such as
storing the fuel in a heated building or a heated
storage tank, or using cold temperature additives.
Fuel Quality — Must Comply With ASTM
Standards
The quality of Biodiesel fuel may vary widely. Only
fuel produced by a BQ9000 supplier to the
following specifications may be blended to meet
biodiesel blend B6 – B20 fuel meeting ASTM
specification D-7467:
Petrodiesel fuel meeting ASTM specification
D-975 and biodiesel fuel (B100) meeting ASTM
specification D-6751
Fuel Oxidation Stability — Must Use Fuel
Within Six Months Of Manufacture
Biodiesel fuel has poor oxidation stability which
can result in long term storage problems. Fuel
produced to approved ASTM standards, if stored
properly, provides for protection against fuel
oxidation for up to six months.
CAUTION!
Failure to comply with Oil Change requirements
for vehicles operating on biodiesel blends
between 6% and 20% (B6–B20) will result in
premature engine wear. Such wear is not
covered by the New Vehicle Limited Warranty.
CAUTION!
Use of blends greater than 20% is not approved.
Use of blends greater than 20% can result in
engine damage. Such damage is not covered by
the New Vehicle Limited Warranty.
CAUTION!
In the event that the vehicle is filled with
biodiesel and not used for more than a month,
the fuel should either be used up by driving (up
to quarter tank) and filled with standard diesel
blends with less than 5% that is normally
available. This will help prevent the fuel filter
clogging and potential damage to the fuel
injection system due to degraded biodiesel,
which is not covered by the New Vehicle Limited
Warranty.

23_JT_OM_EN_USC_t.book Page 422

426TECHNICAL SPECIFICATIONS
NOTE: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 climatized
Number 2 diesel fuel or dilute the Number 2 diesel fuel with 50% Number 1 diesel fuel. This will provide better protection from fuel gelling or wax-plugging of the
fuel filters.Fuel Selection — 3.0L 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 Sulfur
Highway Diesel fuel (500 ppm Sulfur maximum) to avoid damage to the
emissions control system. For most year-round service, Number 2 diesel fuel
meeting ASTM specification D-975 Grade S15 will provide good performance.
We recommend you use a blend of up to 5% biodiesel, meeting ASTM
specification D-975 with your diesel engine.
This vehicle is compatible with biodiesel blends greater than 5% but no
greater than 20% biodiesel meeting ASTM specification D-7467 provided the
shortened maintenance intervals are followed as directed.
Diesel Exhaust Fluid — 3.0L Diesel Engine Mopar® Diesel Exhaust Fluid (DEF)(API Certified) or equivalent that has been
API Certified to the ISO 22241 standard. Use of fluids not API Certified to ISO
22241 may result in system damage.
