2. Install the air cleaner cover onto the housing assemblylocating tabs.
3. Latch the spring clips and lock the air cleaner cover to the housing assembly.
Draining Fuel/Water Separator Filter
The fuel filter/water separator filter housing is located
above the rear axle next to the fuel tank. The best access to
this water drain valve is from under the vehicle.
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.
If water is detected in the water separator while the engine
is running, or while the ignition switch is in the ON
position, the “Water In Fuel Indicator Light” will illumi-
nate and an audible chime will be heard. At this point, you
should stop the engine and drain the water from the filter
housing.

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.
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 your authorized
dealer for service.
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 environment. Contact an
authorized dealer, service station, or government agency
for advice on recycling 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 posi-
tion, 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, follow the directions for “Priming If The Engine
Has Run Out Of Fuel.”
Underbody Mounted Fuel Filter Replacement
NOTE:
Using a fuel filter that does not meet the manufac-
turer’s filtration and water separating requirements can
severely impact fuel system life and reliability.
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. 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.
6. Remove the used filter cartridge from the housing and dispose of it according to your local regulations.
7. Wipe the sealing surfaces of the lid and housing clean.
8. Install a new o-ring into the ring groove on the filter housing and lubricate with clean engine oil.
NOTE: WIF (Water In Fuel) sensor is re-usable. Service kit
comes with new o-ring for filter canister and WIF sensor.
Priming If The Engine Has Run Out Of Fuel
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.
1. Add a substantial amount of fuel to the tank, approxi- mately 2 to 5 gal (8L to 19L).

2. Press ignition switch twice without your foot on braketo put vehicle in Run position. This will activate the in
tank fuel pump for approximately 30 seconds. Repeat
this process twice.
3. Start the engine using the “Normal Starting” procedure. Refer to “Starting Procedures” in “Starting and Operat-
ing” for further information.
CAUTION!
The starter motor will engage for approximately 30
seconds at a time. Allow two minutes between crank-
ing intervals.
NOTE: The engine may run rough until the air is forced
from all the fuel lines.
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.
NOTE:
• Use of biodiesel mixture in excess of 20% can negatively
impact the fuel filter’s ability to separate water from the
fuel, resulting in high pressure fuel system corrosion or
damage.
• In addition, commercially available fuel additives are
not necessary for the proper operation of your diesel
engine.
• For extreme cold conditions, Mopar Premium Diesel
Fuel Treatment is recommended to assist with cold
starting.

Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned in front of the radiator
and the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air rap-
idly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through another
hose to the intake manifold of the engine. This cooling
process enables more efficient burning of fuel resulting in
fewer emissions.
To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and radiator
clean and free of debris. Periodically check the hoses
leading to and from the charge air cooler for cracks or loose
clamps resulting in loss of pressure and reduced engine
performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immediately
if the “Brake System Warning Light” indicates system
failure.The brake master cylinder has a translucent plastic reser-
voir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.

Fuel Selection 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, No. 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 MOPAR Diesel Exhaust Fluid (API Certified) (DEF) 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.
NOTE: If climatized or diesel Number 1 ULSD fuel is not
available, and you are operating below (20°F/-6°C), in
sustained arctic conditions, Mopar Premium Diesel Fuel
Treatment (or equivalent) is recommended to avoid gell-
