NOTE:
• Use of biodiesel mixture in excess of 20%
can negatively impact the fuel filter's abil-
ity to separate water from the fuel, resulting
in high pressure fuel system corrosion or
damage.
• In addition, commercially available fuel ad-
ditives are not necessary for the proper
operation of your diesel engine.
• For extreme cold conditions, "Mopar Pre-
mium Diesel Fuel Treatment" is recom-
mended to assist with cold starting.

Diesel Exhaust Fluid

Diesel Exhaust Fluid (DEF) sometimes known
simply by the name of its active component,
UREA—is a key component of selective cata-
lytic reduction (SCR) systems, which help
diesel vehicles meet stringent emission regu-
lations. 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 wa-
ter vapor.
Refer to "Fluids And Lubricants" in "Techni-
cal Specifications" for further information.

HOISTING

A conventional floor jack may be used at the
jacking locations. Refer to the graphics that
show jacking locations. However, a floor jack
or frame hoist must never be used on any
other parts of the underbody.
CAUTION!
Never use a floor jack directly under the
differential housing of a loaded truck or
damage to your vehicle may result.
