Do not use alcohol-based additives to
improve cetane quality, to prevent fuel
gelling or any other use. The use of alcohol
additives may result in damage to the fuel
injectors and system. See
The Vehicle Warranty may not cover
repairs needed to correct the effects of
using an aftermarket product that does
not meet Ford specifications in your fuel.
RUNNING OUT OF FUEL - 6.8L
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you run out of fuel:
•
You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal. With keyless ignition, just start
the engine. Crank time will be longer
than usual.
•
Normally, adding 1 gal (3.8 L) of fuel is
enough to restart the engine. If the
vehicle is out of fuel and on a steep
grade, more than 1 gal (3.8 L) may be
required.
•
The service engine soon indicator may
come on. See
RUNNING OUT OF FUEL - 6.7L
DIESEL
Avoid running out of fuel as this allows air
to enter the fuel system, which makes
restarting your vehicle difficult.
If your vehicle runs out of fuel:
•
If your vehicle is equipped with dual
fuel tanks, adding 4 gal (15 L) to 5 gal
(19 L) of fuel is enough to restart the
engine. If your vehicle is out of fuel and
on a steep grade, more than 4 gal
(15 L) to 5 gal (19 L) may be required.
•
The fuel system must be primed before
attempting to restart the engine.
•
Use caution not to overheat and
damage the starter by cranking the
engine for an excessive period. You
may need to crank the engine for a
longer time than normal. If the engine
fails to start in 30 seconds, turn the
ignition to the off position and wait for
two minutes before cranking the engine
again.
•
Any remaining trapped air self-purges
from the fuel system once the engine
starts running.
•
The engine may run rough and produce
white smoke while air is in the fuel
system. This is normal and should stop
after a short period.
Purging Air from the Fuel System
Turn the ignition key to on for 30 seconds,
then turn it to off. Do this six times in a row
to purge any trapped air from the fuel
system.
SELECTIVE CATALYTIC
REDUCTION SYSTEM
Your vehicle has a selective catalytic
reduction system to help reduce emission
levels of oxides of nitrogen from the
exhaust system. The system automatically
injects diesel exhaust fluid into the exhaust
system to enable correct selective catalytic
reduction system function.
