SERVICING AND MAINTENANCE 323
10. Lubricate o-ring on the cap with clean engine oil.
11. Install the new fuel filter cartridge onto the cap.
12. Insert the cap and filter into the housing with
clockwise rotation, use a socket to tighten.
13. Push the ignition switch twice without your foot on the
brake to place vehicle in RUN position. This will
activate the in tank fuel pump for approximately 30
seconds. Repeat this process twice to prime the fuel
system. Start the engine using the Normal Starting
procedure. After engine start, verify the fuel filter cap
does not leak.
PRIMING IF THE ENGINE HAS RUN OUT
O
F FUEL — DIESEL ENGINE
1. Add a substantial amount of fuel to the tank, approx-
imately 2 to 5 gal (8L to 19L).
2. Push ignition switch twice without your foot on brake
to put vehicle in RUN position. This will activate the in
tank fuel pump for approximately 30 seconds.
Repeat this process twice to prime the fuel system.
3. Start the engine using the Normal Starting procedure
Ú page 130.
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 nega-
tively 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.
INTERVENTION REGENERATION
S
TRATEGY — MESSAGE PROCESS FLOW
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.

DIESEL EXHAUST FLUID
Diesel Exhaust Fluid (DEF) sometimes known simply by
the name of its active component, UREA—is a key
component of Selective Catalytic Reduction (SCR)
systems, which help diesel vehicles meet stringent
emission regulations. DEF is a liquid reducing agent that
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.
WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be grass
or leaves coming into contact with your exhaust system.
Do not park or operate your vehicle in areas where your
exhaust system can contact anything that can burn.
