WARNING!
Do not use alcohol or gasoline as a fuel
blending agent. They can be unstable un-
der certain conditions and hazardous or
explosive when mixed with diesel fuel.
Diesel fuel is seldom completely free of wa-
ter. To prevent fuel system trouble, drain the
accumulated water from the fuel/water sepa-
rator using the fuel/water separator drain pro-
vided on the fuel filter housing. If you buy
good quality fuel and follow the cold weather
advice above, fuel conditioners should not be
required in your vehicle. If available in your
area, a high cetane “premium” diesel fuel
may
offer improved cold-starting and
warm-up performance.
CAUTION!
If the “Water in Fuel Indicator Light” re-
mains on, DO NOT START engine before
you drain the water from the fuel filter(s) to
avoid engine damage. Refer to “Draining
Fuel/Water Separator Filter” in “Servicing
And Maintenance” in your Diesel Supple-
ment
at www.mopar.com/en-us/care/
owners-manual.html (U.S. Residents) or
www.owners.mopar.ca (Canadian Residents)
for further information.
