WARNINGS
Throughout this guide, you will find warnings identified by the
symbol
. Warnings remind you to be especially careful to reduce the
risk of personal injury.
BREAKING-IN YOUR VEHICLE
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed to allow parts to adjust
themselves to other parts.
Drive your new vehicle at least 500 miles (800 km) before towing a
trailer. Make sure you use the specified engine oil by checking the engine
oil specification chart underEngine oilin theMaintenance and
Specificationschapter.
Do not add friction modifier compounds or special break-in oils during
the first few thousand miles (kilometers) of operation, since these
additives may prevent piston ring seating. SeeEngine oilin the
Maintenance and Specificationschapter of this supplement for more
information on oil usage.
DIESEL ENGINE INFORMATION
The diesel engine fuel system is a pressurized two-stage filtration system
and consists of:
•a frame-mounted diesel fuel conditioner module (DFCM) / primary
filter with an electric fuel pump and water drain,
•an engine-mounted secondary fuel filter,
•a fuel injector for each cylinder (8 total),
•a high-pressure fuel pump,
•a high-pressure fuel rail for each cylinder bank (2 total) and
•numerous high-pressure pipes from the high-pressure pump to the
rails, and rails to the injectors.
The DFCM acts as a primary fuel filter/water separator which removes
both water and impurities from the fuel. The engine mounted filter filters
finer impurities from the diesel fuel. The engine-mounted fuel filter and

the DFCM filter should be changed at the recommended service interval
or when indicated by the message centerLOW FUEL PRESSURE
message. Refer to thescheduled maintenance informationin this
supplement for more information.
The DFCM should be drained at regular intervals or when indicated by
the message center message and water in fuel indicator light. SeeFuel
filter/water separatorin theMaintenance and Specificationschapter.
The fuel injection system is controlled through the powertrain control
module (PCM).
Fuel is drawn from the fuel tank by a frame-mounted electric fuel pump
located inside the DFCM and provides pressurized fuel to the engine.
The fuel pump contains a pressure relief valve for overpressure
protection in the event of restricted flow.
Engine protection mode
Ford diesel engines are equipped with engine protection and emission
control systems. These systems monitor critical temperatures and
pressures, and modify engine operation accordingly. These features are
intended to modify engine performance characteristics. If these modified
engine performance characteristics persist for an extended period or the
service engine soon
or powertrain malfunction/reduced
power/electronic throttle control light
is illuminated, seek service
from your authorized dealer.
Lubrication system
It is important to change the engine oil at the recommended service
intervals to maintain oil viscosity. Extending the oil and filter change
interval beyond the recommended interval can negatively affect engine
performance, fuel economy and engine life. Refer toEngine oilin the
Maintenance and Specificationschapter.
Fast start glow plug system
The diesel engine glow system consists of:
•eight glow plugs (one per cylinder)
•the glow plug control module (GPCM)
•engine coolant temperature (ECT) sensor
•barometric pressure (BARO) sensor
•environmental temperature sensor

If the vehicle’s speed is limited or the vehicle has entered an
idle-only mode
If the vehicle’s speed is limited or in an idle-only mode, the SCR system
may be limiting the vehicle’s functions due to low or contaminated diesel
exhaust fluid (DEF). Check the DEF. SeeSelective catalytic reduction
(SCR) systemin theMaintenance and Specificationschapter for more
information.
Cold weather starting
It is recommended that the engine block heater be used for starting
when the temperature is -10°F (-23°C) or colder. Refer toEngine block
heater (if equipped)in theDrivingchapter of theOwner’s Guide.
When operating in cold weather, use Motorcraftcetane improvers or
non alcohol-based cetane improvers from a reputable manufacturer.
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 3 (off) and wait
30 seconds before trying again.
WARNING: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.
WARNING:Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard and causes
engine performance problems.
1. Turn the key to on without turning the key to start.Do not start the
engineuntil the glow-plug pre-heat indicator
turns off.
2. When the glow plug pre-heat
indicator turns off, turn the key to
start, then release the key as soon
as the engine starts. The glow plugs
may remain on for a period of time after engine start. If the engine is not
started before the glow plug activation time ends, the glow plugs will
need to be reset 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.

Use only a diesel engine that has been configured for use with
high sulfur diesel fuel in markets with diesel fuel that has sulfur
content greater than 15 ppm. Using low sulfur diesel fuel (16–500
ppm) or high sulfur diesel fuel (greater than 500 ppm) in a diesel
engine designed to use only Ultra Low Sulfur Diesel fuel may
result in damage to engine emission control devices and the
aftertreatment system, potentially rendering the vehicle
inoperable. Engine damage from using the improper type of fuel
is not covered under your warranty.
Vehicles with engines configured for use with high sulfur diesel fuel will
only be made available for sale in countries where ULSD fuel is generally
not available or mandated by the government. Vehicles originally sold in
a ULSD fuel market that are subsequently exported to non-ULSD fuel
markets will need to be retrofitted (at the customer’s expense using Ford
authorized dealer service parts) in order to be reliably operated on
non-ULSD fuel.
Diesel fuel is adjusted seasonally for cold temperature. For best results
at temperatures below 20°F (-7°C), it is recommended to use a diesel
fuel which has been seasonally adjusted for the ambient temperature.
SeeCold weather operationin theDrivingchapter of this supplement.
BIODIESEL
This vehicle may be operated on diesel fuels containing up to 20%
biodiesel, also known as B20.
To help achieve acceptable engine performance and durability when
using biodiesel in your vehicle:
•Confirm the biodiesel content of the fuel to be B20 (20% biodiesel) or
less.
•Only use biodiesel fuel of good quality that complies with industry
standards.
•Follow the recommended service maintenance intervals section in the
Schedule Maintenancechapter.
•Do not store biodiesel fuel in the fuel tank for more than 1 month.
•Consider changing brands or reducing biodiesel content if you have
cold temperature fuel gelling issues or a frequentLOW FUEL
PRESSUREmessage appearing.
•Do not use raw oils, fats or waste cooking greases.
Use of biodiesel in concentrations greater than 20% may cause damage
to your vehicle, including engine and/or exhaust after-treatment

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.
Selective Catalytic Reduction (SCR) System
Your vehicle is equipped with a selective catalytic reduction (SCR)
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 SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled during the oil
change service interval. See thescheduled maintenance informationin
this supplement for more information. 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 message center will indicate
whether the DEF level is ok or if it is less than 1/2 full. A message will
automatically be displayed in the message center when the DEF level is
low and needs to be refilled. When you see this message you should refill
your tank. SeeMessage centerin theInstrument Clusterchapter of
yourOwner’s Guidefor message center functions. For instructions on
refilling your DEF tank, seeFilling the DEF tanklater in this section.
DEF warning messages and vehicle operations
WARNING:Diesel Exhaust Fluid (DEF) must be refilled when
low or replaced when contaminated or the 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 fluid is not replaced, the vehicle will become limited to
idle speed only once stopped. In these conditions, be cautious where
you stop the vehicle because you may not be able to drive long
distances and will not be able to maintain highway speeds until DEF is
refilled or replaced.
