PRIMING IF THE ENGINE HAS RUN OUT
O
F FUEL — DIESEL ENGINE
1. Add a substantial amount of fuel to the
tank, approximately 2 to 5 gal (8L to 19L).
2. Push ignition switch twice without your foot
o
n brake to 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
p
rocedure Ú page 144.
NOTE:
The engine may run rough until the air is forced
f
r
om all the fuel lines.
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 addi-
tives are not necessary for the proper opera-
tion of your diesel engine.
For extreme cold conditions, "Mopar®
Premium Diesel Fuel Treatment" is recom-
mended to assist with cold starting.

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.
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 approxi-
mately 30 seconds at a time. Allow two min-
utes 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 explo
-
sive when mixed with diesel fuel.
CAUTION!
Due to lack of lubricants in alcohol or gaso-
line, the use of these fuels can cause dam-
age to the fuel system.
