SERVICING AND MAINTENANCE 365
3. Start the engine using the Normal Starting
procedure Ú page 143.
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.

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.
Refer to Instrument Cluster Display for further
information Ú page 120.
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 reacts with engine
exhaust in the presence of a catalyst to convert
smog-forming Nitrogen Oxides (NOx) into harmless
nitrogen and water vapor.
For further information Ú page 424.
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 oper-
ate your vehicle in areas where your exhaust sys-
tem can contact anything that can burn.
