Turn on the headlights. If the lights are dim,
do not go on at all or when the ignition is
turned to START the lights become dim or
go out, the battery connections may be
loose or corroded, or the battery may be
discharged. If there is a clicking or
stuttering sound coming from the engine
compartment when you turn the key to
START, this may also indicate a loose or
corroded battery connection.
Check the battery connections at the
battery posts, cable connection to the
engine grounding point and at the starter
connection.
If you suspect a discharged battery, have
it checked and corrected.
•
The gearshift lever must be in P (Park)
or N (Neutral) in order for the starter
to operate.
• Try operating the starter switch several
times. This operation may clean
potentially corroded contacts or make
the switch temporarily operable until
you can reach the dealer.
• If all electrical connections are tight
and you need assistance to start, refer
to Jump Starting in the Roadside
Emergencies chapter of your Owner ’s
Manual.
If engine cranks but won ’t start
Prolonged starter cranking (in excess of 10
seconds) could cause damage to the
starter motor or the high-pressure fuel
pump. •
Check the fuel gauge. You may be out
of fuel. If the gauge shows that there
is fuel in the tank, the trouble may be
in the electrical system or the fuel
system. If equipped with an auxiliary
tank, be sure that the tank control
switch is set for the tank with fuel and
not on an empty tank.
• Leaving your ignition key turned to on
for over two minutes without starting
may make starting difficult because
the glow plugs will cease activation.
Reset the system by turning the ignition
key to off and then back to on again.
Note: If the system is out of fuel and the
engine will not start, do not continue
cranking the engine. Continued cranking can
damage the high-pressure fuel pump.
If the engine runs hot
The following could cause the engine to
overheat:
• Lack of coolant
• Dirty cooling system.
• Plugged radiator fins, A/C condenser
and/or oil cooler
• Malfunctioning fan drive
• Driving with frozen coolant
• Sticking thermostat
• Overloading or pulling heavy trailers
during hot weather
• Grill or radiator air blockage
• Slipping or missing drive belt
• Plugged or very dirty air filter

Super Duty (TFA) , enUSA Introduction

Diesel Exhaust Fluid (DEF) (If
Equipped) With the key in the on position,
lights when the DEF is
contaminated or low. See
Selective Catalytic Reduction System
(page
21).
Glow Plug Pre-Heat With the key in the on position,
lights when the glow plug heat
is necessary as a starting aid.
Wait until the light goes off before starting.
See
Starting a Diesel Engine (page 10).
After you start the engine, the light should
turn off. When the engine is cold, the light
should always light for a short period.
Water In Fuel During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel lights when the engine
is running, stop your vehicle as soon as
safely possible, shut off the engine, then
drain the fuel and water separator. See
Fuel Quality
(page 15). Allowing water
to stay in the fuel system, after the water
in fuel indicator lights, could result in
extensive damage or failure of the fuel
injection system. WARNING
Do not drain the fuel and water
separator while the engine is running.
Fuel may ignite if the separator is
drained while the engine is running or the
vehicle is moving. Note:
Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.

STARTING A DIESEL ENGINE
Read all starting instructions carefully
before you start your vehicle.
For temperatures below 32°F (0°C), the
use of the correct grade engine oil is
essential for proper operation. Refer to
Engine oil specifications for more
information. See Technical
Specifications (page 57).
Your vehicle may be equipped with a cold
weather starting strategy that prevents
severe engine damage by assisting in
engine lubrication warm-up. In extremely
cold ambient temperatures, this strategy
activates and prevents the accelerator
pedal from being used for 30 seconds after
starting your vehicle. A message will
appear in the information display as your
vehicle warms up. By not allowing the
accelerator pedal to be used, the engine
oil is allowed to properly lubricate the
bearings preventing engine damage due
to lack of proper lubrication. After the 30
second warm-up period, the accelerator
pedal will be operational again and a
message will appear informing you the
vehicle is ok to drive.
When starting the engine in extremely cold
temperatures (-15°F [– 26°C]), it is
recommended to allow the engine to idle
for several minutes before driving the
vehicle.
Before starting the engine check the
following:
• Make sure all occupants have fastened
their safety belts.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the gearshift lever is in
P
(Park)
• Turn the ignition key to the on position. Note:
Do not press the accelerator during
starting.
Cold Weather Starting WARNINGS
Do not use starting fluid, such as
ether, in the air intake system (see
air filter decal). Such fluid could
cause immediate explosive damage to the
engine and possible personal injury Do not add gasoline, gasohol, alcohol
or Kerosene to diesel fuel. This
practice creates a serious fire hazard
and causes engine performance problems. It is recommended that the engine block
heater be used for starting when the
temperature is -10°F (-23°C) or colder.
Refer to Engine block heater later in this
chapter for more information.
When operating in cold weather,
Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer may be used as
needed.
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine fails to start, turn the key to
position 3 (off) and wait 30 seconds
before trying again.
1. Turn the key to on without turning the
key to start. Do not start the engine
until the glow-plug indicator turns off.
10
Super Duty (TFA) , enUSA Starting and Stopping the Engine

2.
When the glow plug pre-heat indicator
turns off, turn the key to start and
release the key as soon as the engine
starts. After starting the engine, the
glow plugs may remain on for a period.
If you do not start the engine before
the glow plug activation time ends, you
will need to reset the glow plugs by
turning the key to off.
3. After the engine starts, allow it to idle for about 15 seconds. This is to protect
the engine. Do not increase engine
speed until the oil pressure gauge
indicates normal pressure.
Cold Weather Operation
Note: Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See Technical
Specifications (page 57).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
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
Technical Specifications
(page 57). Your vehicle is equipped with 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 recommended that
the fuel level in your tank should not drop
below 1⁄4 full. This helps prevent air from
entering the fuel system and stalling the
engine.
Your vehicle is equipped with a selective
catalyst 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, you
must take special care to prevent damage
to the tank. See
Selective Catalytic
Reduction System (page 21).
In cold weather below 32°F (0°C), the
engine may slowly increase to a higher idle
speed if left idling in P (Park). 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/or ice away from inside
the air filter assembly. Remove the air
cleaner cover and the pleated paper filter,
leaving the foam filter in and remove any
snow or ice. Make sure you install the foam
filter correctly in place. Remove any debris,
snow or ice on the foam filter by brushing
the surface with soft brush. Once you have
cleared all of the debris, reinstall the air
filter and assembly.
Do not use water, solvents, or a hard brush
for cleaning the foam filter.

Note: Additional aftermarket electrical
loads operated during engine warm up may
affect the performance of the rapid heat
supplemental heater. The optional rapid heat feature is an
electrically powered device that provides
supplemental heat during engine warm up.
During initial warm up, you should use a
mid to low blower speed for maximum
effectiveness. When operating in
automatic mode (when equipped) the
climate control unit determines the
appropriate blower speed for existing

Installation – Engine-mounted fuel
filter
1. Install the new filter into the filter
bracket. Turn the filter clockwise to
lock it in place.
2. Reconnect both fuel lines.
Note: Using a fuel that has more than
average impurities may require you to
replace the fuel filter more frequently than
the service interval specifies.
Note: You will need to purge the system of
air after removal or changing of the filter.
See purging air from the fuel system later
in this chapter.
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.
After filter service, a no start or rough
running engine may indicate that air is
entering the system through the filter bowl
seal or drain. Make sure the drain is tight
and you tightened the filter bowl to the
mechanical stop.
SELECTIVE CATALYTIC
REDUCTION SYSTEM
Your vehicle is equipped with a selective
catalytic reduction system to help reduce
emission levels of oxides of nitrogen from
the exhaust of the diesel engine. The
system automatically injects Diesel
Exhaust Fluid (DEF) into the exhaust
system to enable proper selective catalytic
reduction function. Importance of maintaining the
Diesel Exhaust Fluid (DEF) level
In order for the selective catalytic reduction
system to operate properly, the DEF level
must be maintained. Generally, the DEF
tank should be filled during the oil change
service interval. See General
Maintenance Information (page 59).
However, certain conditions or driving
styles, such as trailer towing or fast rates
of acceleration, will require the refilling of
the DEF tank more often.
The engine control unit will monitor the
amount of fluid available in the DEF tank.
Running a system check in the information
display will indicate whether the DEF level
is ok or if it is less than 1/2 full. A message
will display in the information display when
the DEF level is low and needs to be
refilled. When you see this message, you
should refill your tank. See the Information
displays chapter of your Owner ’s Manual
for information display functions. For
instructions on refilling your DEF tank, see
filling the Diesel Exhaust Fluid (DEF) tank
in this supplement.
Diesel Exhaust Fluid (DEF)
warning messages and vehicle
operations WARNINGS
Diesel Exhaust Fluid (DEF) must be
refilled when low or replaced when
contaminated or your vehicle speed
will be speed limited to 50 mph (80 km/h).
In these conditions, drive with caution and
refill DEF immediately. If the DEF becomes
empty or contaminated and fluid is not
replaced, your vehicle will become limited
to idle speed only once stopped. In these
conditions, be cautious where you stop
your vehicle because you may not be able
to drive long distances and will not be able
to maintain highway speeds until you refill
or replace the DEF.

REFUELING
Fueling Tips WARNING
Do not use starting fluid such as
ether or gasoline in the diesel air
intake system. Such fluids can cause
immediate explosive damage to the engine
and possible personal injury. 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 (don ’t depress the nozzle trigger as
far). If air is allowed to enter the fuel system
(during fuel filter change or if you run out
of fuel) the engine will purge the trapped
air as it runs. 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.
An engine that suddenly becomes noisy or
operates poorly after a fuel fill could be
using substandard fuel (for example, high
water content, low cetane rating or
gasoline in the fuel). You should purchase
diesel fuel from a reputable station that
sells a large amount of diesel fuel.
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.

FUEL SHUTOFF
In the event of a moderate to severe
collision, this vehicle is equipped with a
fuel pump shut-off feature that stops the
flow of fuel to the engine. Not every impact
will cause a shut-off.
After an accident, if the engine cranks but
does not start, this switch may have been
activated.
This switch is located on the passenger
’s
side of the instrument panel. Open the
front passenger door and remove the small
access panel The switch has a red button on top of it.
To reset the switch:
1. Turn the ignition off.
2. Check the fuel system for leaks. 3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition on.
5. Wait a few seconds and return the key
to off.
6. Make another check for leaks.
Running Out Of DEF (Diesel
Exhaust Fluid)
If your vehicle runs out of DEF, it will enter
into a speed limited mode and can also
enter into an idle-only mode. Normal
vehicle operation will not resume until DEF
is refilled. See Selective Catalytic
Reduction System (page 21).
Contact roadside assistance for help in
finding a retailer that sells DEF. See the
Customer Assistance chapter in the
Owner ’s Manual for more information.
JUMP STARTING THE VEHICLE WARNINGS
The gases around the battery can
explode if exposed to flames, sparks,
or lit cigarettes. An explosion could
result in personal injury or vehicle damage. Batteries contain sulfuric acid which
can burn skin, eyes and clothing, if
contacted.
Use only an adequate-sized cable
with insulated clamps.
Preparing Your Vehicle
Note:
Do not attempt to push-start your
automatic transmission vehicle. Automatic
transmissions do not have push-start
capability. Attempting to push-start a
vehicle with an automatic transmission may
cause transmission damage.
