alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See Capacities and
Specifications (page 431).
Your vehicle has a fuel and water separator
that recirculates fuel from the engine to
help prevent fuel filter clogging. To avoid
engine fuel starvation during cold weather
operation of
32°F (0°C) or below, we
recommend that the fuel level in your tank
should not drop below ¼ full. This helps
prevent air from entering the fuel system
and stalling the engine.
Your vehicle has a selective catalytic
reduction system that uses Diesel Exhaust
Fluid (DEF) to operate properly. You need
to replenish your vehicle ’s DEF at certain
intervals. When filling your vehicle ’s DEF
tank in cold weather, take special care to
prevent damage to the tank. See
Selective Catalytic Reductant System
(page
196).
In cold weather below
32°F (0°C), the
engine may slowly increase to a higher idle
speed if you leave it idling in park (P). As
the engine warms-up, the engine sound
level decreases due to the activation of
PCM-controlled sound reduction features.
If you operate your vehicle in a heavy
snowstorm or blowing snow conditions,
snow and ice can clog the engine air
induction. If this occurs, the engine may
experience a significant reduction in power
output. At the earliest opportunity, clear
all the snow and ice away from inside the
air filter assembly. Remove the air cleaner
cover and the air filter and remove any
snow or ice. Remove any debris, snow or
ice, on the foam filter by brushing the
surface with a soft brush. Once you have
cleared all of the debris, reinstall the air
filter and cover.
Do not use water, solvents, or a hard brush
for cleaning the foam filter. WARNING:
To reduce the risk of
vehicle damage and personal burn
injuries, do not start your engine with the
air cleaner removed and do not remove
it while the engine is running.
In order to operate the engine in
temperatures of 32°F (0°C) or lower, read
the following instructions:
• Make sure that the batteries are of
sufficient size and are fully charged.
Check other electrical components to
make sure they are in optimum
condition.
• Use the proper coolant solution at the
concentration recommended
protecting the engine against damage
from freezing.
• Try to keep the fuel tank full as much
as possible at the end of operation to
prevent condensation in the fuel
system.
• Make sure you use proper cold weather
engine oil and that it is at its proper
level. Also, if necessary, make sure to
follow the engine oil and filter change
schedule found under the Special
operating conditions section listed in
the scheduled maintenance
information.
• At temperatures of
-9°F (-23°C) or
below, it is recommended that you use
an engine block heater to improve cold
engine starting.
• If operating in arctic temperatures of
-20°F (-29°C)
or lower, consult your
truck dealer for information about
special cold weather equipment and
precautions.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201804, Fourth-Printing Starting and Stopping the Engine

We recommend the following cold
weather idling guidelines:
•
You can use Motorcraft® cetane
improvers or non-alcohol-based
cetane improvers from a reputable
manufacturer as needed.
• Maintain the engine cooling system
properly.
• Avoid shutting the engine down after
an extensive idling period. Drive your
vehicle for several miles with the
engine at normal operating
temperatures under a moderate load.
• Consider using an engine block heater.
• For extended idle times use an
approved idle speed increase device.
Winter Operating Tips for Arctic
Operation -20°F (-29°C) and Below
The following information is a guideline
only and is not to be the only source of
possible solutions in resolving extreme
cold temperature issues.
Starting Aids WARNING: Do not use starting
fluid, for example ether, in the air intake
system. Such fluid could cause
immediate explosive damage to the
engine and possible personal injury.
The use of the factory engine block heater
assists in engine starting in extreme cold
ambient temperatures
See Engine Block
Heater (page 181). Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
the upfitter switches in the overhead
console. This allows the operator to
elevate the idle RPM for extended idle
periods, as well as aftermarket equipment
such as PTO operation. You must configure
this feature even if ordered from the
factory. See your authorized dealer for
required upfitting.
Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to
200 mi
(320 km) in snowfall or extreme rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note: Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
Refer to Air filter and restriction gauge in
the Maintenance chapter for more
information. See
Changing the Engine
Air Filter (page 362).

Operation in Standing Water
Ingestion of water into the diesel engine
can result in immediate and severe
damage to the engine. If driving through
water, slow down to avoid splashing water
into the intake. If the engine stalls, and you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
SWITCHING OFF THE ENGINE
- 6.7L DIESEL
Switch the ignition off.
To help prolong engine life, we
recommended you allow the engine to idle
for three to five minutes, especially after
any of the following:
•
Continuous engine speed.
• High ambient temperature.
• High GVW or GCW operation, for
example heavy loads or trailers.
This allows the turbo charged engine to
cool down.
ENGINE IDLE SHUTDOWN
Your vehicle may be equipped with an
engine idle shutdown system. This system
automatically shuts down your engine
when it has been idling in P (Park) or N
(Neutral) for five minutes (parking brake
set) or 15 minutes (parking brake not set).
When the engine idle shutdown process
has started: •
A chime sounds and the information
display will show ENGINE TURNS OFF
IN 30 (seconds) and start counting
down
• You can restart the five or 15-minute
timer by changing the position of the
accelerator pedal, brake pedal or the
park brake within the final 30 seconds
• When the timer reaches zero, the
engine shuts down and this message
will appear in your information display
ENGINE TURNED OFF
• One minute after the engine has shut
down, the electrical system simulates
key off, even though the ignition is still
in the on position, initiating normal
accessory delay period
• You must move the ignition to the off
position to reset the system before
restarting your vehicle.
The engine idle shutdown idle timer does
not start if:
• The engine is operating in power
take-off mode.
• The engine coolant temperature is
below 60°F (16°C).
• The exhaust emission control device is
regenerating.
ENGINE BLOCK HEATER
(IF
EQUIPPED) WARNING:
Failure to follow
engine block heater instructions could
result in property damage or serious
personal injury. WARNING:
Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201804, Fourth-Printing Starting and Stopping the Engine

Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
For cold climates that are below
0°F
(-18°C) needing a temporary battery
installation. Order the cold climate pack.
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source. We recommend that you do the following
for a safe and correct operation:
•
Make sure your vehicle is parked in a
clean area, clear of combustibles.
• locate the block heater cord in the front
tow hook pocket.
• Use a 16-gauge outdoor extension cord
that is product certified by
Underwriter ’s Laboratory (UL) or
Canadian Standards Association
(CSA). This extension cord must be
suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard. •
Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord
plug connections are free and clear of
water. This could cause an electric
shock or fire.
• Make sure the heater, heater cord and
extension cord are firmly connected.
• Check for heat anywhere in the
electrical hookup once the system has
been operating for approximately 30
minutes.
• Make sure the system is unplugged and
properly stowed before starting and
driving your vehicle. Make sure the
protective cover seals the prongs of the
block heater cord plug when not in use.
• Make sure the heater system is
checked for proper operation before
winter.
Using the Engine Block Heater
Make sure the receptacle terminals are
clean and dry prior to use. Clean them with
a dry cloth if necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It achieves
maximum temperature after
approximately three hours of operation.
Using the heater longer than three hours
does not improve system performance and
unnecessarily uses electricity.

• Keep the fuel pump nozzle in contact
with the fuel container while filling.
• Do not use a device that would hold
the fuel pump handle in the fill position.
Fuel Filler Cap WARNING:
The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler door, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury. WARNING:
If you do not use the
proper fuel filler cap, excessive pressure
or vacuum in the fuel tank may damage
the fuel system or cause the fuel cap to
disengage in a collision, which may result
in possible personal injury. Note:
If you must replace the fuel filler cap,
replace it with a fuel filler cap that is
designed for your vehicle. The customer
warranty may be void for any damage to the
fuel tank or fuel system if the correct

Fueling Tips
If air is allowed to enter the fuel system the
engine automatically purges any trapped
air. To purge the air sooner: prior to engine
start, prime the system by turning the key
to on for 30 seconds then to off. Repeat
this several times. The engine may run
rough and produce white smoke while air
is in the system. This is normal.
Use only clean, approved containers that
will prevent the entry of dirt or water
whenever you store diesel fuel.
Diesel fuel must not be stored in a
galvanized container. The fuel will dissolve
the zinc in the galvanized container. The
zinc will then remain in the fuel. If you run
the contaminated fuel through the engine,
the zinc will deposit in the fuel injectors
causing expensive-to-repair damage.
Diesel fuel dispensing nozzle fill rate
Your vehicle has a fuel fill pipe that is able
to accept fuel up to
20 gal (76 L) per
minute from an 1.2 in (30 mm)
fuel-dispensing nozzle. Pumping fuel at
greater flow rates may result in premature
nozzle shut-off or spit back.

Truck stops have pumps and nozzles
designed for larger, heavy-duty trucks.
When refueling at truck stops: if the nozzle
shuts off repeatedly when refueling, wait
5–
10 seconds; then use a slower rate of
flow, do not depress the nozzle trigger as
far.
Refueling
When fueling your vehicle do the following:
1. Fully open the fuel tank filler door until
it engages and remove the fuel tank
filler cap. The fuel tank filler cap has
an indexed design with a 1/4 turn
on/off feature. Carefully turn the filler
cap counterclockwise until it spins off. 2. Insert the fuel pump nozzle up to the
first notch on the nozzle A. Keep it
resting on the cover of the fuel tank
filler pipe opening. 3.
Hold the fuel pump nozzle in the lower
position B when refueling. Holding the
fuel pump nozzle in the higher position
A may affect the flow of fuel and shut
off the fuel pump nozzle before the fuel
tank is full. 4.
Slightly raise the fuel pump nozzle and
then slowly remove it.
5. Replace the fuel tank filler cap and close the fuel tank filler door.
Note: Do not attempt to start the engine
if you have filled the fuel tank with incorrect
fuel. Incorrect fuel use can cause damage
not covered by the vehicle Warranty. Have
your vehicle checked immediately.

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the ignition key to the on
position for 15 seconds without cranking
the engine. If the service engine soon
indicator blinks eight times, it means that
the vehicle is not ready for I/M testing; if
the service engine soon indicator stays on
solid, it means that your vehicle is ready
for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle. SELECTIVE CATALYTIC
REDUCTANT SYSTEM - DIESEL
Your vehicle may have a selective catalytic
reduction system. The system helps 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.
Note:
Selective catalytic reduction systems
are not fitted to vehicles in markets where
only high-sulfur diesel fuel is available.
Diesel Exhaust Fluid Level
In order for the system to operate correctly
you must maintain the diesel exhaust fluid
level.
A warning message appears in the
information display when the diesel
exhaust fluid level is low. If a warning
message appears, refill the diesel exhaust
fluid tank as soon as possible. See
Information Messages (page 128).
Filling the Diesel Exhaust Fluid
Tank WARNING:
Keep diesel exhaust
fluid out of reach of children. Avoid
contact with skin, eyes or clothing. In
case of contact with your eyes, flush
immediately with water and get prompt
medical attention. In case of contact
with your skin, clean immediately with
soap and water. If you swallow any
diesel exhaust fluid, drink plenty of
water, call a physician immediately.
