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 filter.
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.Diesel fuel is seldom completely free of water. If water is
detected in the water separator while the engine is
running or while the ignition switch is in the ON/RUN
position, the “Generic Warning Light” will illuminate
and the specific message, “Service Fuel Filter” will ap-
pear in the Electronic Vehicle Information Center (EVIC).
If this occurs you should stop the engine and drain the
water from the filter housing.
NOTE:
Please see your authorized dealer for draining the
fuel/water separator and fuel filter replacement.
Purchasing good quality fuel and by following the cold
weather advice above, fuel conditioners should not be
required in your vehicle.
NOTE: If available in your area, a high cetane “pre-
mium” diesel fuel may offer improved cold-starting and
warm-up performance.

CAUTION!
If the “Generic Warning Light” remains on and a
“Service Fuel Filter” message displays, DO NOT
START engine before you drain the water from the
fuel filter housing to avoid engine damage. Please
see your authorized dealer for draining the fuel
filter/water separator and fuel filter replacement.
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 meeting ASTM
specification 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 speci-
fication 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 main-
tenance schedule is subject to shorter intervals.
The oil and filter change along with fuel filter replace-
ment 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. Refer to the “Maintenance
Chart” in the “Maintenance Schedules” section for fur-
ther direction.
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.
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 require-
ments if you use blends of Biodiesel between 6% and 20%
(B6–B20). There are no unique restrictions for the use of
B5.

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.
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient tem-
peratures, 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 build-
ing 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 specifi-
cations 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.
64 STARTING AND OPERATING
Page 68 of 130
CAUTION!
Failure to comply with these Oil Change and fuel
filter requirements for vehicles operating on bio-
diesel 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%.
ADDING FUEL
The fuel cap is located behind the fuel filler door on the
left side of the vehicle. If the fuel cap is lost or damaged,
be sure the replacement cap is for use with this vehicle.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.

Page 69 of 130

NOTE:
•When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the fuel filler cap until you hear a “clicking”
sound. This is an indication that the fuel filler cap is
properly tightened.
• Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.
WARNING!
A fire may result if fuel is pumped into a portable
container that is on a truck bed. You could be burned.
Always place fuel containers on the ground while
filling.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause
severe damage to the engine fuel system. Proper main-
tenance of the engine fuel filter and fuel tank is essential.
Refer to “Maintenance Procedures” in “Maintaining Your
Vehicle” for further information.
Bulk Fuel Storage — Diesel Fuel
If you store quantities of fuel, good maintenance of the
stored fuel is also essential. Fuel contaminated with
water will promote the growth of “microbes.” These
microbes form “slime” that will clog the fuel filtration
system and lines. Drain condensation from the supply
tank and change the line filter on a regular basis.
NOTE: When a diesel engine is allowed to run out of
fuel, air is pulled into the fuel system.

If the vehicle will not start, refer to “Maintenance
Procedures/Priming If The Engine Has Run Out Of Fuel”
in “Maintaining Your Vehicle” for further information.
WARNING!
Do not open the high pressure fuel system with the
engine running. Engine operation causes high fuel
pressure. High pressure fuel spray can cause serious
injury or death.
Diesel Exhaust Fluid Storage
Diesel Exhaust Fluid (DEF) is considered a very stable
product with a long shelf life. If DEF is kept in tempera-
tures between 10° and 90°F (-12° and 32°C), it will last a
minimum of one year.DEF is subject to freezing at the lowest temperatures. For
example, DEF may freeze at temperatures at or below
12° F (-11° C). The system has been designed to operate in
this environment.
NOTE:
When working with DEF, it is important to know
that:
• Any containers or parts that come into contact with
DEF must be DEF compatible (plastic or stainless
steel). Copper, brass, aluminum, iron or non-stainless
steel should be avoided as they are subject to corrosion
by DEF.
• If DEF is spilled, it should be wiped up completely.
Adding Diesel Exhaust Fluid
NOTE: Driving conditions (altitude, vehicle speed, load,
etc.) will effect the amount of DEF that is used by your
vehicle.
68 STARTING AND OPERATING
Page 72 of 130

CAUTION!(Continued)
•Do not attempt to start your engine if DEF is
accidentally added to the diesel fuel tank as it can
result in severe damage to your engine, including
but not limited to failure of the fuel pump and
injectors.
• Never add anything other than DEF to the tank –
especially any form of hydrocarbon such as diesel
fuel, fuel system additives, gasoline, or any other
petroleum-based product. Even a very small
amount of these (less than 100 parts per million or
less than 1 oz. per 78 gallons) will contaminate the
entire DEF system and will require replacement. If
owners use a container, funnel or nozzle when
refilling the tank, it should either be new or one
that is has only been used for adding DEF. MOPAR
provides an attachable nozzle with its DEF for this
purpose. 3. Stop filling the DEF tank immediately when any of the
following happen:
•DEF stops flowing from the fill bottle into the DEF tank.
• DEF splashes out the filler neck.
• DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF filler neck.
Filling The Def Tank In Cold Climates
Since DEF will begin to freeze at 12°F (-11°C), your vehicle is
equipped with an automatic DEF heating system. This
allows the DEF injection system to operate properly at
temperatures below 12°F (-11°C). If your vehicle is not in
operation for an extended period of time with temperatures
below 12°F (-11°C), the DEF in the tank may freeze. If the
tank is overfilled and freezes, it could be damaged. There-
fore, do not overfill the DEF tank.
Extra care should be taken when filling with portable
containers to avoid overfilling.
