Tread Wear Indicators
Tread wear indicators are in the original equipment tires to
help you in determining when your tires should be
replaced.

Tire Tread

These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth
becomes 1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire should be
replaced.
For further information
Úpage 354.
Life Of Tire
The service life of a tire is dependent upon varying factors
including, but not limited to:
Driving style.

 Tire pressure - Improper cold tire inflation pressures can
cause uneven wear patterns to develop across the tire tread. These abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire replacement.

 Distance driven.
 Performance tires, tires with a speed rating of V or
higher, and Summer tires typically have a reduced
tread life. Rotation of these tires per the vehicle sched-
uled maintenance is highly recommended.
NOTE:Wheel valve stem must be replaced as well when installing
new tires due to wear and tear in existing tires.
Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressures. The
manufacturer strongly recommends using tires equivalent
to the originals in size, quality and performance when
replacement is needed. Refer to the paragraph on “Tread
Wear Indicators” in this section. Refer to the Tire And
Loading Information Placard or the Vehicle Certification
Label for the size designation of your tire. The Load Index
and Speed Symbol for your tire will be found on the original
equipment tire sidewall. For more information relating to the Load Index and Speed
Symbol of a tire
Úpage 346.
It is recommended to replace the two front tires or two rear
tires as a pair. Replacing just one tire can seriously affect
your vehicle’s handling. If you ever replace a wheel, make
sure that the wheel’s specifications match those of the
original wheels.
It is recommended you contact an authorized tire dealer or
original equipment dealer with any questions you may
have on tire specifications or capability. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle.
1 — Tread Wear Indicators
WARNING!

Tires and the spare tire should be replaced after six
years, regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You could
lose control and have a collision resulting in serious
injury or death.

WARNING!
 Do not use a tire, wheel size, load rating, or speed
rating other than that specified for your vehicle.
Some combinations of unapproved tires and wheels
may change suspension dimensions and perfor -
mance characteristics, resulting in changes to
steering, handling, and braking of your vehicle. This
can cause unpredictable handling and stress to
steering and suspension components. You could
lose control and have a collision resulting in serious
injury or death. Use only the tire and wheel sizes with
load ratings approved for your vehicle.
 Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.

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 FCA recommends Mopar® total care 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.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in closed
areas they may cause respiratory harm.
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.
CAUTION!

Direct contact of air fresheners, insect repellents,
suntan lotions, or hand sanitizers to the plastic,
painted, or decorated surfaces of the interior may
cause permanent damage. Wipe away immediately.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the A-pillar,
visible from outside of the vehicle through 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.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug nuts/bolts
and clean or remove any dirt or oil before tightening.
Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.Spare Tire Torque Specifications

FUEL REQUIREMENTS – DIESEL ENGINE
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.
Use good quality diesel fuel from a reputable supplier in
your vehicle. For most year-round service, No. 2 diesel fuel
meeting ASTM (formerly known as the American Society
for Testing and Materials) specification 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 climatized No. 2 diesel fuel or dilute the No.
2 diesel fuel with 50% No. 1 diesel fuel. This will provide
better protection from fuel gelling or wax-plugging of the
fuel filters.
Diesel fuel is seldom completely free of water. To prevent
fuel system trouble, drain the accumulated water from the
fuel/water separator using the fuel/water separator drain
provided 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.
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 an
authorized dealer for service.
 A maximum blend of 5% biodiesel meeting ASTM spec -
ification D-975 may be used with your diesel engine
without any adjustments to regular service schedules.
 Commercially available fuel additives are not neces -
sary for the proper operation of your diesel engine.
 No. 1 Ultra Low Sulfur diesel fuel should only be used
where extended arctic conditions (-10°F or -23°C)
exist.
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 311.
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.
WARNING!
Do not use alcohol or gasoline as a fuel blending agent.
They can be unstable under certain conditions and
hazardous or explosive when mixed with diesel fuel.
CAUTION!
If the Water in Fuel Indicator Light remains on, DO NOT
START engine before you drain the water from the fuel
filter(s) to avoid engine damage
Úpage 321.
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.

372TECHNICAL SPECIFICATIONS
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.
Fuel Water Separation — Must Use
Mopar® Approved Fuel Filter Elements
Biodiesel fuel has a natural affinity to water and water
accelerates microbial growth. Your Mopar® filtration
system is designed to provide adequate fuel water
separation capabilities.
Fuel In Oil Dilution — Must Adhere To
Required Oil Change Interval
Fuel dilution of lubricating oil has been observed with the
use of Biodiesel fuel. Fuel in oil must not exceed 5%. To
ensure this limit is met your oil change interval must be
maintained within the suggested schedule. The regular
use of biodiesel between 6% and 20% requires intervals
shorter than the outlined 10,000 miles (16,000 km) and
must not exceed the suggested schedule. When routinely
operating on biodiesel between 6% and 20%, oil and filter
replacement intervals must not exceed 8,000 miles
(12,875 km) or six months, whichever comes first.
Biodiesel Fuel Filter Change Intervals
The use of biodiesel requires more frequent fuel filter
change intervals. When operating on biodiesel between
6% and 20%, fuel filter replacement intervals should be
every second oil change, and must not exceed
16,000 miles (25,750 km).
NOTE:Under no circumstances should oil change intervals
exceed 8,000 miles (12,875 km) or 6 months, if regular
operation occurs with 6% - 20% biodiesel blends. Under no
circumstances should fuel filter replacement intervals
exceed every second oil change and must not exceed
16,000 miles (25,750 km), if regular operation occurs
with 6% - 20% biodiesel blends. Failure to comply with
these Oil Change and fuel filter requirements for vehicles
operating on biodiesel blends up to B20 may result in
premature engine wear. Such wear is not covered by the
New Vehicle Limited Warranty. The engine may suffer
severe damage if operated with concentrations of
biodiesel higher than 20%.
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.
