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 requirements
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.
88 STARTING AND OPERATING

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 sys-
tem is designed to provide adequate fuel water separa-
tion 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 with in the suggested schedule. The
regular use of biodiesel between 6% and 20% requires
intervals shorter than the outlined 10,000 miles and must
not exceed the suggested schedule. When routinely op-
erating on biodiesel between 6% and 20%, oil and filter
replacement intervals must not exceed 8,000 Miles or 6
months, which ever comes first.
Biodiesel Fuel Filter Change Intervals
The use of biodiese requires intervals shorter than the
outlined 30,000 miles (48 280 km) and must not exceed
the suggested schedule. When operating on biodiesel
between 6% and 20%, fuel filter replacement intervals
must not exceed 20,000 Miles (40 233 km).
NOTE:Under no circumstances should oil change inter-
vals 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 intervals ex-
ceed 20,000 miles (40 233 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 bio-
diesel higher than 20%.

DIESEL EXHAUST FLUID
Your vehicle is equipped with a Selective Catalytic Re-
duction system to meet the very stringent diesel emis-
sions standards required by the Environmental Protec-
tion Agency.
The purpose of the SCR system is to reduce levels of NOx
(oxides of nitrogen emitted from engines) that are harm-
ful to our health and the environment to a near-zero level.
Small quantities of Diesel Exhaust Fluid (DEF) is injected
into the exhaust upstream of a catalyst where, when
vaporized, it converts smog-forming nitrogen oxides
(NOx) into harmless nitrogen (N2) and water vapor
(H2O), two natural components of the air we breathe.
You can operate with the comfort that your vehicle is
contributing to a cleaner, healthier world environment
for this and generations to come.
System Overview
This vehicle is equipped with a Diesel Exhaust Fluid
(DEF) injection system and a Selective Catalytic Reduc-
tion (SCR) catalyst to meet the emission requirements.
The DEF injection system consists of the following com-
ponents:
•DEF tank
• DEF pump
• DEF injector
• Electronically-heated DEF lines
• NOx sensors
• Temperature sensors
• SCR catalyst
90 STARTING AND OPERATING

The DEF injection system and SCR catalyst enable the
achievement of diesel emissions requirements; while
maintaining outstanding fuel economy, drivability,
torque and power ratings.
Refer to “Electronic Vehicle Information Center (EVIC)”
or “Driver Information Display (DID)” in “Understand-
ing Your Instrument Panel” for system messages and
warnings.
NOTE:
•Your vehicle is equipped with a DEF injection system.
You may occasionally hear an audible clicking noise
from under the vehicle at a stop. This is normal
operation.
• The DEF pump will run for a period of time after
engine shutdown to purge the DEF system. This is
normal operation and may be audible from the rear of
the vehicle.ADDING FUEL — 1500 DIESEL MODELS

CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
•Never have any smoking materials lit in or near the
vehicle when the fuel door is open or the tank is
being filled.
• Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and may cause the “Malfunction Indicator
Light” to turn on.
• A fire may result if fuel is pumped into a portable
container that is inside of a vehicle. 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.
94 STARTING AND OPERATING

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.

STARTING AND OPERATING 95

NOTE:
•The DEF gauge may take up to five seconds to update
after adding a gallon or more of Diesel Exhaust Fluid
(DEF) to the DEF tank. If you have a fault related to the
DEF system, the gauge may not update to the new
level. See your authorized dealer for service.
• The DEF gauge may also not immediately update after
a refill if the temperature of the DEF fluid is below 12F
(-11C). The DEF line heater will possibly warm up the
DEF fluid and allow the gauge to update after a period
of run time. Under very cold conditions, it is possible
that the gauge may not reflect the new fill level for
several drives.CAUTION!
• To avoid DEF spillage, and possible damage to the
DEF tank from overfilling, do not “top off” the DEF
tank after filling.
• DO NOT OVERFILL. DEF will freeze below 12ºF
(-11ºC). The DEF system is designed to work in
temperatures below the DEF freezing point, how-
ever, if the tank is overfilled and freezes, the
system could be damaged.
• When DEF is spilled, clean the area immediately
with water and use an absorbent material to soak
up the spills on the ground.
• 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.
