additives, which contain
alcohols, organo-metallic
additives, or water
emulsifiers.
Caution
If the vehicle is accidentally
refueled with gasoline, do not
continue driving the vehicle.
Driving the vehicle will damage
the fuel system. Have the vehicle
towed to a qualified technician to
have the gasoline removed from
the tank and fuel system. Refuel
with Ultra Low Sulfur Diesel fuel.
It is also recommended to have
the fuel system flushed with Ultra
Low Sulfur Diesel, to ensure all
gasoline is removed.
Some conditions, such as dirty fuel,
may decrease fuel filter life and a
CHANGE FUEL FILTER message
may come on in the Driver
Information Center (DIC).
Climate Grade Diesel Fuels
At temperatures below 0 °C (32 °F),
avoid using biodiesel blends above
5% by volume. Using such a fuel
may cause fuel filter plugging,
system gelling, and freezing, which
may adversely impact vehicle
starting.
Severe winter grade diesel fuel,
such as 1-D diesel fuel or Arctic
grade diesel fuel, can be used in
extreme cold temperatures (below
−18 °C or 0 °F); however, doing so
will reduce power and fuel economy.
Avoid using severe winter grade fuel
in warm or hot climates. It can result
in stalling, poor starting, and
damage to the fuel injection system.
Fuels improperly blended for cold
temperature operation may result in
restricted fuel filters. The vehicle is
equipped with a fuel heating system
to prevent gelling or waxing of
conventional diesel fuel and
biodiesel blends, but may not
prevent all cases.
In case of severe winter conditions,
the fuel filter may 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. The fuel filter may
need to be replaced. See Fuel Filter
Replacement (Diesel) 0 222.
Biodiesel
Biodiesel is a renewable fuel
produced from vegetable oils or
animal fats that have been
chemically modified to make it
compatible with diesel fuel.
Caution
Do not use home-made biodiesel
or home test kits because the
quality cannot be verified by
approved scientific methods. Do
not use raw vegetable oil or other
unmodified bio-oils, fats,
