G/T AIR FILTER MAINTENANCE
Clean Engine Air Filter
The scheduled air filter cleaning interval is 30,
000 miles (48,280 km), or if in a dusty
environment the engine air filter should be
checked periodically to ensure optimal air flow.

1. Spray the air filter with the recommended
Mopar® air filter cleaner or apply mild
dishwashing detergent and water and let sit
for at least 10 minutes to loosen dir before
rinsing.

NOTE:Never use strong detergents, high pressure, or
gasoline on the air filter.
2. Rinse the air filter with cool low-pressure water applied from the inside (clean side) out in
order to flush the dirt out of the filter. Continue
to rinse the filter until all traces of the cleaner
have been removed.
NOTE:It may be necessary to repeat steps 1 and 2 if the
air filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry
naturally.
NOTE:Do not use forced air pressure as it may damage
the filtering capabilities of the filter’s microfibers
and also void its warranty.
DRAINING FUEL/WATER SEPARATOR
F
ILTER — DIESEL ENGINE
The fuel/water separator filter housing is located
inside the frame rail, behind the left front wheel.
The best access to this water drain valve is from
under the vehicle.
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 Water In Fuel Indicator
Light will illuminate and an audible chime will be
heard. At this point, you should stop the engine
and drain the water from the filter housing.
Fuel Filter Assembly

If the Water In Fuel Indicator Light comes on and a
single chime is heard while you are driving, or with
the ignition in the ON position, there may be a
problem with your water separator wiring or
sensor. See an authorized dealer for service.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.
1 — Water In Fuel Drain Valve
CAUTION!
If the Water In Fuel Indicator Light remains on,
DO NOT START the engine before you drain water
from the fuel filter to avoid engine damage.

22_DT_OM_EN_USC_t.book Page 412

SERVICING AND MAINTENANCE413
Upon proper draining of the water from the fuel
filter, the Water In Fuel Indicator Light will remain
illuminated for approximately 10 seconds. If the
water was drained while the engine was running,
the Water In Fuel Indicator Light may remain on for
approximately three minutes.
NOTE:Care should be taken in disposing of used fluids
from your vehicle. Used fluids, indiscriminately
discarded, can present a problem to the envi -
ronment. Contact an authorized dealer, service
station, or government agency for advice on recy -
cling programs and for where used fluids and
filters can be properly disposed of in your area.
Drain the fuel/water separator filter when the
Water In Fuel Indicator Light is ON. Within
10 minutes of vehicle shutdown, turn the filter
drain valve (located on the bottom of the filter
housing) counterclockwise to drain fuel/water,
then turn the ignition switch to the ON position,
and allow any accumulated water to drain. Leave
the drain valve open until all water and
contaminants have been removed. When clean
fuel is visible, close the drain valve by turning it
clockwise, and turn the ignition switch to OFF.
If more than two ounces or 60 milliliters of fuel
have been drained Ú page 414.

EPLACEMENT — DIESEL ENGINE
NOTE:Using a fuel filter that does not meet the manufac -
turer’s filtration and water separating require -
ments can severely impact fuel system life and reli -
ability. Under normal conditions the diesel fuel
filter should be replaced every 20,000 miles (every
other oil change). If the vehicle is being used in
severe operating conditions, or In certain
geographical areas of the country (Pennsylvania,
New York, Ohio, Maryland, West Virginia, Arkansas,
Oklahoma, Kansas, Iowa, Missouri and Nebraska)
due to fuel cleanliness issues, it’s recommended
to replace the fuel filter every 10,000 miles.
Fuel Filter Assembly

1. Turn engine off.

2. Place a drain pan under the fuel filter assembly.
3. Open the water drain valve, and let any accumulated water drain.
4. Close the water drain valve.
5. Remove bottom cover using a strap wrench. Rotate counterclockwise for removal. Remove
the used o-ring and discard it.
CAUTION!
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appropriate
container.
Do not prefill the fuel filter when installing a
new fuel filter. There is a possibility debris
could be introduced into the fuel filter during
this action. It is best to install the filter dry and
allow the in-tank lift pump to prime the fuel
system.

1. Add a substantial amount of fuel to the tank,
approximately 2 to 5 gal (8 L to 19 L).

2. Press ignition switch twice without your foot on brake to put vehicle in ON/RUN position. This
will activate the in tank fuel pump for approxi -
mately 30 seconds. Repeat this process twice. 3. Start the engine using the “Normal Starting”
procedure Ú page 144.
NOTE:The engine may run rough until the air is forced
from all the fuel lines.
NOTE:
Use of biodiesel mixture in excess of 20% can
negatively impact the fuel filter's ability to sepa -
rate water from the fuel, resulting in high pres -
sure fuel system corrosion or damage.
In addition, commercially available fuel addi -
tives are not necessary for the proper operation
of your diesel engine.
For extreme cold conditions, "Mopar® Premium
Diesel Fuel Treatment" is recommended to

TRATEGY — MESSAGE PROCESS FLOW
(D
IESEL ENGINE)
This engine meets all required diesel engine
emissions standards. To achieve these emissions
standards, your vehicle is equipped with a
state-of-the-art engine and exhaust system. These
systems are seamlessly integrated into your
vehicle and managed by the Powertrain Control
Module (PCM). The PCM manages engine
combustion to allow the exhaust system’s catalyst
to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, your vehicle has the ability to alert you
to additional maintenance required on your vehicle
or engine Ú page 114.
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.
CAUTION!
The starter motor will engage for approximately
30 seconds at a time. Allow two minutes
between cranking intervals.
WARNING!
Do not use alcohol or gasoline as a fuel blending
agent. They can be unstable under certain
conditions and be hazardous or explosive when
mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gasoline,
the use of these fuels can cause damage to the
fuel system.

ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasoline to increase
octane. Gasoline blended with MMT provides no
performance advantage beyond gasoline of the
same octane number without MMT. Gasoline
blended with MMT reduces spark plug life and
reduces emissions system performance in some
vehicles. The manufacturer recommends that
gasoline without MMT be used in your vehicle. The
MMT content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask the
gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
FUEL SYSTEM CAUTIONSNOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
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
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.
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can impair
engine performance and damage the emis -
sions control system.
An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic
converter to overheat. If you notice a pungent
burning odor or some light smoke, your engine
may be out of tune or malfunctioning and may
require immediate service. Contact an autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
CAUTION!
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.9

470TECHNICAL SPECIFICATIONS
Diesel fuel is seldom completely free of water. To
prevent fuel system trouble, drain the
accumulated water from the fuel/water separator
filter 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 Number 2 Ultra Low Sulfur
diesel fuel or Number 2 Ultra Low Sulfur Climatized
diesel fuels.
NOTE:
If you accidentally fill the fuel tank with gasoline
or DEF 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 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.
Number 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.
For further direction Ú
page 402.
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!
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
Ú page 412.
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.

TECHNICAL SPECIFICATIONS471
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 with in the
suggested schedule. The regular use of biodiesel
between 6% and 20% requires intervals shorter
than the outlined 10,000 miles (16,100 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 (12,900 km) or six months,
which ever 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 six
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 require
-
ments 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.
