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”
133.
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
assist with cold starting.

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.
