Refueling
Diesel fuel can foam when filling the
tank. This can cause the automatic
pump nozzle to shut off, even if the
tank is not full. If this happens, wait
for the foaming to stop, and then fill
the tank more slowly. See Filling the
Tank 0 62.
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. To help avoid this, fill
the tank slowly and only until the
nozzle shuts off. Do not top it off.
Clean up any spilled fuel.
Accidental Refueling with
Gasoline
Caution
If the vehicle is accidentally
refueled with gasoline, do not
continue driving the vehicle
except to get to a location where
it can be stopped safely. Driving
the vehicle will damage the fuel
system. Have the vehicle towed
to a qualified technician to have
the gasoline removed from the
tank, preferably until the fuel
gauge reads near E (Empty).

Diesel fuel.
What Fuel to Use in

maximum) will cause damage to
the exhaust after-treatment

be covered by the vehicle
warranty. Do not use marine,
locomotive, or boiler distillate fuel
since it may contain higher sulfur
levels.
Diesel Fuel Types
Fuels are blended for seasonal
changes. Diesel Type A fuel is
blended to ensure vehicles operate
in extreme cold temperatures. This
fuel, however, may cause some
