SCHEDULED MAINTENANCE
The scheduled maintenance services in thescheduled maintenance
informationof this supplement are required because they are
considered essential to the life and performance of your vehicle.
Use only recommended fuel, lubricants, fluids and service parts
conforming to Ford specifications. Motorcraft parts are designed and
built for best performance in your vehicle.
FUEL REQUIREMENTS - CHOOSING THE RIGHT FUEL: VEHICLES
OPERATED WHERE ULTRA LOW SULFUR DIESEL FUEL IS
REQUIRED (UNITED STATES/CANADA/PUERTO RICO/U.S. VIRGIN
ISLANDS AND OTHER LOCALES)
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) number 1-D
or 2-D diesel fuel in your 6.0L or 6.4L diesel engine.The engine
and exhaust system were designed to only use this fuel. Look for the
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm Sulfur
Maximum)label on fuel pumps when purchasing your fuel.
Using low sulfur diesel fuel (16-500 ppm) or high sulfur diesel
fuel (greater than 500 ppm) in a 6.4L diesel engine designed to
use only Ultra Low Sulfur Diesel fuel will cause certain emission
components to malfunction which may also cause the Check
Engine(
)light to illuminate indicating an emissions-related
concern.
Number 1-D or winter blend number 2-D fuel is recommended at
temperatures below 20°F (-7°C) (seeCold weather operationin the
Drivingchapter of this supplement). Diesel fuel containing no more

If the “Check Fuel Cap” message comes on and stays on after you start
the engine, the fuel filler cap may not be properly installed. Turn off the
engine, remove the fuel filler cap, align the cap properly and reinstall it.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The vehicle warranty may
be void for any damage to the fuel tank or fuel system if the
correct genuine Ford or Motorcraft fuel filler cap is not used.
The fuel system may be under pressure. If the fuel filler cap is
venting vapor or if you hear a hissing sound, wait until it stops
before completely removing the fuel filler cap. Otherwise, fuel may
spray out and injure you or others.
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.

AIR FILTER RESTRICTION GAUGE AND AIR FILTER
REPLACEMENT
Air filter restriction gauge:
The restriction gauge, located on
the upper housing of the air filter
assembly, measures the vacuum
inside the air filter. The more the air
filter is restricted (dirty, clogged),
the higher the vacuum reading
Check the air filter restriction gauge
whenever the hood is raised to
perform general engine maintenance
at least every 7,500 miles (12,000 km). If the vehicle is operated in
extremely dusty conditions, check the gauge at least every 500 miles
(800 km), or two weeks, whichever comes first.
Change the air filter when the gauge reads 25 inches (635 mm). Engine
performance and fuel economy are adversely affected when the
maximum restriction is reached.
Blowing-out the air filter element with compressed air is not
recommended as the compressed air may damage the filter paper.
Note:It is not possible to determine the level of filter clogging by visual
appearance alone. A filter which appears to be dirty may actually have
several thousand miles (kilometers) of life remaining.
Always use the underhood air filter restriction gauge to
determine when the air filter element needs to be changed. The
warning light on the instrument cluster should not be used
exclusively for determining when the air filter element needs
changing.

After installation of the new filter
element, reset the gauge by pressing
the reset button on top of the
gauge.
Note:If the vehicle is operated in a
heavy snow storm, in blowing snow
or the vehicle is equipped with a
snowplow, the engine air filter
element may become partially
clogged with snow and/or ice. If this
occurs, the engine may experience a
significant reduction in power output. The vehicle may be driven under
these conditions for up to 200 miles (320 km) without damage to the
engine or related components.
At the earliest opportunity, clear all snow and ice from the air induction
system and reset the restriction gauge by pressing the button on the end
of the gauge. If the air filter restriction gauge vacuum reads above the
second line after clearing snow and/or ice, then replace the filter. Reset
filter restriction gauge after changing the air filter element.
The air filter warning message on the instrument cluster may be used, in
addition to the underhood restriction gauge, to monitor the condition of
the air filter element. Refer to theEngine air filterwarning light in this
chapter of the supplement.
Air filter replacement:
When replacing the air filter element, use the Motorcraft air filter
element listed inMotorcraft Part Numberslater in this chapter.
To reduce the risk of vehicle damage and/or personal burn
injuries do not start your engine with the air filter removed and
do not remove it while the engine is running.
Failure to use the correct air filter element may result in severe
engine damage.
•E-series air filter element:
1. Disconnect the hoses from the air filter outlet tube.

it begins to restrict the filter. The soot gathered inside the filter needs to
be periodically cleaned. The soot can be cleaned in two different ways;
passive regeneration and active regeneration. Both methods occur
automatically and require no actions from the driver/operator. During
either one of these regeneration methods you may notice an
increase/change in exhaust noise/tone.
Passive regeneration
In passive regeneration, the exhaust constituents / temperature are at an
appropriate level where some soot can be reduced or oxidized (burned)
thus cleaning the filter. This method occurs naturally as a result of
normal engine operating conditions (at varying levels due to drive
patterns).
Active regeneration
If there is not enough passive regeneration naturally occurring due to
vehicle drive patterns, the engine control system will initiate an active
regeneration. In an active regeneration, the filter is cleaned by raising
the exhaust temperature to a point where the soot is burned away. This
is accomplished through various engine actions which raise the exhaust
temperature in the oxidation catalyst/DPF system to an appropriate high
level where the soot is burned off. After the soot is burned off, the
exhaust temperature and back-pressure (restriction) fall back to normal
levels.
Filter service/maintenance
Over time a slight amount of ash will build up in the DPF which is not
removed during the regeneration process. The DPF may need to be
removed for ash cleaning at approximately 120,000 miles (193,000 km)
or greater (actual mileage can vary greatly depending upon
engine/vehicle operating conditions) and replaced with a new or
remanufactured (ash cleaned) part. The filter may need to be replaced
at approximately 250,000 miles (400,000 km) depending upon
engine/vehicle operating conditions. In both cases the engine control
system will set a service light (
) to inform you to bring the vehicle
to the dealer for service.
If there are any issues with the oxidation catalyst/DPF system a service
light (
or) will be set by the engine control system to inform
you to bring the vehicle into a dealership for service.

MINOR TROUBLESHOOTING GUIDE
Air purge procedure
Turn the key on for 30 seconds, then turn off. Repeat procedure four or
five times.
If the engine won’t crank
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 a discharged battery is suspected, have it checked and corrected.
Battery posts, terminals and related accessories contain lead and
lead compounds.Wash hands after handling.
•For vehicles with manual transmissions,the clutch pedalmustbe
fully depressed in order for the starter to operate.
•For vehicles with automatic transmissions,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. Should the switch be
corroded, this operation may clean the 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 toJump startingin theRoadside Emergencieschapter of your
Owner’s Guide(F-Super Duty) or refer to theJump startingsection
in theRoadside Emergencieschapter of this supplement (E-Series).
If engine cranks but won’t start
Prolonged starter cranking (in excess of 30 seconds) could cause
damage to the starter motor.
•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.
