WARNING
Heat coming from the engine can
cause the fuel to expand and
force the fuel out of the tank.
If something ignites the fuel, a fire
could start and people could be
burned. To help avoid this, try
filling the tank more slowly and fill
the fuel tank only until the
automatic nozzle shuts off. Do not
try to top it off.
Accidental Refueling with
Gasoline
Notice: If any amount of gasoline
is added to the fuel tank, do not
start the engine until the fuel tank
can be drained and refilled with
Ultra Low Sulfur Diesel fuel. Your
dealer can perform this
procedure. If this procedure is
not performed, the vehicle will
run very rough and have reduced
power. Severe engine damage will
occur and would not be covered
by the vehicle warranty.
Cold Weather Operation
Follow the instructions listed
previously under the heading
“ What
Fuel to Use. ”
Notice: Never use home heating
oil or gasoline in the vehicle.
They can cause engine damage
not covered by the vehicle
warranty.
In cold weather, the fuel filter could
become clogged by wax naturally
present in the fuel. To unclog it,
move the vehicle to a warm garage
area and allow the filter to warm up
to between 0°C (32°F) and 10°C
(50°F). You will not need to replace
the filter. Additional information on
the fuel filter follows.
Use of biodiesel blends greater than
B5 (5% blend) should be avoided in
cold temperatures.
Water in Fuel
{
WARNING
Diesel fuel containing water is still
flammable. You could be burned.
If you ever try to drain water from
the fuel, keep sparks, flames, and
smoking materials away from the
mixture.
Notice: If there is water in the
diesel fuel and the weather is
warm or humid, fungus and
bacteria can grow in the fuel.
They can damage the fuel system
and fuel operated heater (FOH) (if
equipped). A diesel fuel biocide
can be used to sterilize the fuel
system. However, the fuel system
may still need to be cleaned. Your
dealer can advise you of the
appropriate solution.
