Note:
Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel significantly
increases your vehicle ’s exhaust emissions
and reduce engine life due to increased
internal wear.
We recommend Top Tier diesel fuel where
available to help minimize engine deposits
and maintain optimal vehicle and engine
performance.
For additional information, visit
www .t op tier g a s. c om .
You should use ultra-low sulfur diesel fuel
designated as number 1-D or 2-D with a
maximum of 15-ppm sulfur in your diesel
vehicle. You can operate your vehicle on
diesel fuels containing up to 20%
biodiesel, also known as B20. These fuels
should meet the ASTM D975 diesel or the
ASTM D7467 B6-B20 biodiesel industry
specifications. Outside of North America,
use fuels meeting EN590 or equivalent
local market standard. Using low-sulfur diesel fuel
(16-500 ppm) or high-sulfur
diesel fuel (greater than 500
ppm) in your diesel engine will cause
certain emission components to
malfunction which could also cause the
service engine soon light to illuminate
indicating an emissions-related concern.
Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 19°F (-7°C), we
recommend using a diesel fuel which has
been seasonally adjusted for the ambient
conditions. Choosing the Right Fuel: Vehicles
Operated Where Ultra Low Sulfur
Diesel Fuel Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory-built high-sulfur
engine (available as a dealer order option
for select markets) or an ultra-low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
authorized dealer service parts. Failure to
use retrofit components other than those
available through your authorized dealer
results in coolant system damage, engine
overheating, selective catalyst reduction
system or diesel particulate filter damage
and possible base engine damage.
Use only a diesel engine 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 could result in damage to engine
emission control devices and the after
treatment system, potentially rendering
the vehicle inoperable.
Vehicles with engines configured for use
with high-sulfur diesel fuel are only
available for sale in countries where
ultra-low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in an ultra-low
sulfur diesel fuel market that are
subsequently exported to non-ultra low
sulfur diesel 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-ultra
low sulfur diesel fuel.

Biodiesel
WARNING: Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel greater than 20%
or any diesel not intended for highway use.
Damage to the fuel injection system, engine
and exhaust catalyst, and diesel particulate
filter can occur if you use an improper fuel.
Red dye is used to identify fuels intended
for agricultural and non-highway use.
You can operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
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. See
General
Maintenance Information (page 664).
• 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
frequently appearing LOW FUEL
PRESSURE message. Use of biodiesel in concentrations greater
than 20% can cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that could
result in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
We recommend SAE 5W-40 oil for fuels
with greater than 5% biodiesel (B5). For
more information about oil change
intervals and other maintenance when
operating on biodiesel.
See Special
Operating Conditions Scheduled
Maintenance
(page 675).
Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in diesel fuel. Ask the service station
attendant to confirm the biodiesel content
of diesel fuel, if you do not see a label on
the fuel pump.
If you plan to park or store your vehicle for
more than 1 month, then you should empty
your vehicle fuel tank of biodiesel fuel. You
should fill the tank with a pure
petroleum-based diesel fuel and run your
vehicle for a minimum of 30 minutes.
Note: Degraded or oxidized biodiesel can
damage fuel system seals and plastics and
corrode steel parts.
During cold weather, if you have problems
operating on biodiesel, you may need to
use diesel fuel with lower biodiesel
content, try another brand or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high-quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.

WHAT IS THE DIESEL
PARTICULATE FILTER
The diesel particulate filter is part of your
vehicle's emissions system and filters
harmful diesel particulates from the
exhaust gas.
HOW DOES THE DIESEL
PARTICULATE FILTER WORK
The diesel particulate filter reduces
emissions by trapping exhaust particles
before they reach the tailpipe. The system
must periodically clean the exhaust
particles that gather inside the filter. This
is carried out in three ways, passive
regeneration, active regeneration and
manual regeneration.
Passive Regeneration
In passive regeneration, the normal
exhaust system temperature cleans the
filter by oxidizing the soot. Cleaning occurs
during normal vehicle operating conditions
due to driving patterns.
Active Regeneration
Once the diesel particulate filter is full,
active regeneration raises the exhaust
temperature to eliminate the particles.
When the engine control module detects
that the diesel particulate filter is nearly
full of particulates, and you are not
operating your vehicle in a manner to allow
effective regeneration, messages appear
in the information display as a reminder
for you to drive your vehicle in order to
clean the diesel particulate filter. If you
drive your vehicle in a manner to allow
effective regeneration, the information
display shows a cleaning exhaust filter
message.
DIESEL PARTICULATE FILTER
PRECAUTIONS WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard. WARNING:
When the Exhaust
Filter Cleaning message appears in the
information display, do not park near
flammable materials, vapors or
structures until filter cleaning is
complete. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.

(If Equipped)

Before you start manual regeneration, do
the following:
•
Shift into park (P) and apply the
parking brake, on stable, level ground.
• Park your vehicle outside of any
structure.
• Park your vehicle 10– 15 ft (3–5 m)
away from any obstructions and away
from materials that can easily combust
or melt, for example paper, leaves,
petroleum products, fuels, plastics and
other dry organic material.
• Make sure there is a minimum of 1/8
tank of fuel.
• Make sure all fluids are at proper levels.
DIESEL PARTICULATE FILTER
MANUAL REGENERATION
LIMITATIONS
You cannot use manual regeneration until
the diesel particulate filter load percentage
has reached 100%. The diesel particulate
filter load percentage fluctuates up and
down when driving your vehicle due to
active and passive regenerations.
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than
25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system.
Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty. STARTING DIESEL PARTICULATE
FILTER MANUAL REGENERATION
Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See
Instrument Cluster Display
(page 178).
If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See
What Is the Diesel Particulate Filter
(page 268). Answer yes to this prompt and
then follow the next prompts regarding
exhaust position required to initiate
manual regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished. You can also drive to
clean the filter. When the system is at the point
of oversaturation, the service
engine warning lamp illuminates
and a message appears in the information
display. You cannot initiate filter cleaning.
You must have your vehicle checked as
soon as possible.
Once manual regeneration starts, engine
speed increases to approximately 1600
rpm and the cooling fan speed increases.
You will hear a change in audible sound
due to engine speed and cooling fan speed
increases.
It is not necessary to open the hood on the
engine compartment. Once manual
regeneration completes, the engine speed
returns to normal idling. The exhaust
system remains very hot for several
minutes even after regeneration is
complete. Do not reposition the vehicle
over materials that could burn until the
