NOTE:Ensure funnel is inserted fully to hold flapper door
open.
3. Pour fuel into funnel opening.
4. Remove funnel from filler pipe, clean off prior to putting back in the jack kit.
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 regulations
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.
CAUTION!
To avoid fuel spillage and overfilling, do not “top off”
the fuel tank after filling.
Avoid Using Contaminated Fuel
Fuel that is contaminated by water or dirt can cause severe
damage to the engine fuel system. Proper maintenance 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
The DEF gauge (located on the instrument cluster) will
display the level of DEF remaining in the tank. Refer to
“Instrument Cluster” and “Instrument Cluster Descrip-
tions” in “Understanding Your Instrument Panel” for fur-
ther information.
NOTE:
•Driving conditions (altitude, vehicle speed, load, etc.)
will effect the amount of DEF that is used in your
vehicle.
• Another factor is that outside temperature can affect
DEF consumption. In cold conditions, 12° F (-11° C) and
below, the DEF gauge needle can stay on a fixed position
and may not move for extended periods of time. This is
a normal function of the system.
• There is an electric heater inside the DEF tank that
automatically works when necessary. And if the DEF
supply does freeze, the truck will operate normally until
it thaws.
DEF Fill Procedure
NOTE: Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for the correct fluid type.
1. Remove cap from DEF tank (located on drivers side of the vehicle or in fuel door).

2. Insert DEF fill adapter/nozzle into DEF tank filler neck.
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 acci-
dentally 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.

CAUTION!(Continued)
•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 (295 liters) will contaminate the
entire DEF system and will require replacement. If
owners use a container, funnel or nozzle when refill-
ing the tank, it should either be new or one that is
has only been used for adding DEF. MOPAR pro-
vides 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, or a
DEF pump nozzle automatically shuts off.
4. Reinstall cap onto DEF tank. 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 tempera-
tures below 12°F (-11°C), the DEF in the tank may freeze. If
the tank is overfilled and freezes, it could be damaged.
Therefore, do not overfill the DEF tank.
Extra care should be taken when filling with portable
containers to avoid overfilling. Note the level of the DEF
gauge in your instrument cluster. You may safely add a
maximum of 2 gallons (7.5 Liters) of DEF from portable
containers when your DEF gauge is reading ½ full.
