FORD F750 2015 13.G Owners Manual

The inlet holes in the side of the assembly are functional. These holes
allow outside air to enter into the outlet assembly. Keep the holes clear
of mud and other foreign material to maintain proper functionality of the
system. One way to keep the holes clear is to spray the outlet assembly
with a hose when washing your vehicle. Failure to keep the functional
holes clear of foreign material may result in blocking or plugging of the
holes.
SWITCHING OFF A DIESEL ENGINE
Allow the engine to idle for three to five minutes before shutting it
down. The larger the engine, the greater the need is for this idling
period.
Note:Try to limit engine idle to 10 minutes. Excessive idling reduces
fuel economy.
ENGINE AUTOMATIC SHUTDOWN (IF EQUIPPED)
WARNING:In the event of engine shutdown, make sure the
vehicle is safely off the road and the problem is remedied prior to
returning to the road. Failure to remove the vehicle from the road
could result in an accident, causing serious injury or death.
This feature either illuminates a light in the instrument cluster or sounds
a tone (or both) indicating that the engine is being shut down due to
high coolant temperature, low engine oil pressure, high diesel particulate
filter soot loading or low engine coolant level. If any of these conditions
exist, the engine automatically shuts down.
If the engine shuts down, you can restart and operate it for 30 seconds
at a time or until you correct the problem. Do not attempt to use this
restarting feature to drive your vehicle very far as serious engine damage
could result.
ENGINE BLOCK HEATER (IF EQUIPPED)
WARNING:Failure to follow engine block heater instructions
could result in property damage or personal injury.
WARNING:Do not use your heater with ungrounded electrical
systems or two-pronged (cheater) adapters. There is a risk of
electrical shock.

Note:The heater is most effective when outdoor temperatures are below
0°F (-18°C).
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 A/C
electrical source.
We recommend that you do the following for safe and correct operation:
•Use a 16-gauge outdoor extension cord that is product certified by
Underwriter’s Laboratory or Canadian Standards Association. This
extension cord must be suitable for use outdoors, in cold
temperatures, and be clearly markedSuitable for Use with Outdoor
Appliances.Never use an indoor extension cord outdoors; it 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 the
heater cord plug connections are free and clear of water. This could
cause an electric shock or fire.
•Make sure your vehicle is parked in a clean area, clear of
combustibles.
•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 driving
your vehicle. Make sure the protective cover seals the prongs of the
block heater cord plug when not in use.
•Keep plug terminals clean and free of dirt and corrosion.
•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 before use. To
clean them, use a dry cloth.
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.

SAFETY PRECAUTIONS
WARNING:Do not overfill the fuel tank. The pressure in an
overfilled tank may cause leakage and lead to fuel spray and fire.
WARNING:The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler inlet, do not refuel until the
sound stops. Otherwise, fuel may spray out, which could cause serious
personal injury.
WARNING:Automotive fuels can cause serious injury or death if
misused or mishandled.
WARNING:The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is pumped
into an ungrounded fuel container.
WARNING:Fuel ethanol and gasoline may contain benzene,
which is a cancer-causing agent.
WARNING:When refueling always shut the engine off and never
allow sparks or open flames near the filler neck. Never smoke
while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.
Observe the following guidelines when handling automotive fuel:
•Extinguish all smoking materials and any open flames before refueling
your vehicle.
•Always turn off the vehicle before refueling.
•Automotive fuels can be harmful or fatal if swallowed. Fuel, such as
gasoline, is highly toxic and if swallowed can cause death or
permanent injury. If fuel is swallowed, call a physician immediately,
even if no symptoms are immediately apparent. The toxic effects of
fuel may not be visible for hours.
•Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
Fuel and Refueling103

•Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
•Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
•Be particularly careful if you are taking Antabuse or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
CHOOSING THE RIGHT FUEL
Note:Do not add after-market fuel additive products to your fuel tank.
We recommend that you use only high quality fuel without after-market
additives or other engine treatments.
Note:Use of any fuel other than those recommended may cause vehicle
damage, a loss of vehicle performance and repairs may not be covered
under warranty.
Gasoline Engine – 6.8L V10
Use only UNLEADED gasoline or UNLEADED gasoline blended with a
maximum of 15% ethanol in your gasoline vehicle.
Do not use:
•fuels containing more than 15% ethanol or E-85 fuel
•fuel containing methanol
•fuels containing metallic based additives, including manganese-based
compounds
•fuels containing the octane booster additive, methylcyclopentadienyl
manganese tricarbonyl (MMT)
•leaded-fuel(The use of leaded fuel is prohibited by law.)
Your vehicle was not designed to use fuels that contain manganese-based
additives. Using fuels not recommended could damage or impair the
emission control system.

Diesel Engine
WARNING:Using low sulfur (16-500 ppm) or high sulfur
(greater than 500 ppm) diesel fuel in a diesel engine designed to
use only Ultra Low Sulfur Diesel fuel causes certain emission
components to malfunction which may also cause the Service Engine
Soon light to illuminate indicating an emissions-related concern. It may
also increase the likelihood of engine oil dilution with fuel which may
lead to major engine damage
WARNING:Do not mix diesel fuel with gasoline, gasohol or
alcohol. This could cause an explosion resulting in personal
injury.
WARNING:Do not add gasoline, gasohol or alcohol to diesel
fuel. This practice creates a serious fire hazard resulting in
personal injury and engine performance problems.
WARNING:Do not use starting fluid such as ether or gasoline.
Such fluids can cause immediate explosive damage to the engine
and possible personal injury.
WARNING:Do not use home heating oil or any diesel fuel not
intended for highway use. Red dye is used to identify fuels
intended for agricultural and non-highway use. Damage to the fuel
injection system, engine and exhaust catalyst can occur if an improper
fuel is used.
Note:Use of any fuel other than those recommended may cause
powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.
Use only Ultra Low Sulfur (15 ppm Sulfur Maximum) No. 1-D or 2-D
diesel fuel in your diesel engine. Diesel fuel No. 1-D or winter diesel fuel
blend of No. 2-D is recommended at ambient temperatures below 20°F
(-7°C). Diesel fuel that is blended with 20% biodiesel maximum may be
used.

Biodiesel fuel is a product converted from renewable fuel sources,
including vegetable oil, animal fat and cooking oil. You should not use
raw, refined, and recycled vegetable/plant oils, greases, and animal fats.
Biodiesel fuel blends must meet requirements of ASTM D7467 standard
specification. See your engine operator’s manual for more information
and restrictions about the use of biodiesel fuel.
Octane Recommendations - Gasoline Engines
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as Regular with
an octane rating below 87,
particularly in high altitude areas. Do not use fuels with a posted octane
rating below 87.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see an authorized dealer to
prevent any engine damage.
RUNNING OUT OF FUEL
Gasoline Engine
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
•You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time takes a few seconds longer
than normal.
•If your vehicle is equipped with dual fuel tanks, adding four–five
gallons (15–19 liters) of fuel is enough to restart the engine. If your
vehicle is out of fuel and on a steep grade, more than four–five
gallons (15–19 liters) may be required.
•The service engine soon indicator may come on. For more
information on the service engine soon indicator, see theInstrument
Clusterchapter.
SeeGeneral informationin theInformation Displayschapter for
information on Miles to Empty.
Diesel Engine
Avoid running out of fuel as this allows air to enter the fuel system,
which makes restarting your vehicle difficult.

the engine.
•Use caution not to overheat and damage the starter by cranking the
engine for an excessive period. You may need to crank the engine for
a longer time than normal. If the engine fails to start in 30 seconds,
turn the ignition to the off position and wait for two minutes before
cranking the engine again.
•Any remaining trapped air self-purges from the fuel system once the
engine starts running.
•The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period.
SeeGeneral informationin theInformation Displayschapter for
information on Miles to Empty.
REFUELING
WARNING:Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
•Read and follow all the instructions on the pump island.
•Turn off your engine when you are refueling.
•Do not smoke if you are near fuel or refueling your vehicle.
•Keep sparks, flames and smoking materials away from fuel.
•Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
•Keep children away from the fuel pump; never let children pump
fuel.
•Do not use personal electronic devices while refueling.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
•Place approved fuel container on the ground.
•DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
Fuel and Refueling107

•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 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.
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 crash, which may result in
possible personal injury.
Note:If you must replace the fuel filler cap, replace it with a fuel filler
cap designed for your vehicle. The customer warranty may be void for
any damage to the fuel tank or fuel system if the correct genuine Ford,
Motorcraft or other certified fuel filler cap is not used.
Your fuel tank filler cap has an indexed design with a quarter–turn on
and off feature. When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise until it spins off.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise a
14–turn until it clicks at least once.
If the check fuel cap light appears in the instrument cluster and stays on
after you start the engine, you not have installed the fuel filler cap
properly.
If the fuel cap light remains on, at the next opportunity, safely pull off
the road, remove the fuel filler cap, align the cap properly and reinstall
it. The check fuel cap light may not reset immediately; it may take
several driving cycles for the indicators to turn off. A driving cycle
consists of an engine start-up (after four or more hours with the engine
off) followed by normal city and highway driving.

FUEL CONSUMPTION
Filling the Tank
The advertised capacity is the indicated capacity and the empty reserve
combined. Indicated capacity is the difference in the amount of fuel in a
full tank and a tank when the fuel gauge indicates empty. Empty reserve
is the amount of fuel in the tank after the fuel gauge indicates empty.
Note:The amount of usable fuel in the empty reserve varies. Do not rely
on it to increase your driving range. When refueling your vehicle after
the fuel gauge indicates empty, you might not be able to refuel the full
amount of the advertised capacity of the fuel tank due to the empty
reserve still present in the tank.
For consistent results when filling the fuel tank:
•Turn the ignition off before fueling. An inaccurate reading results if
you leave the engine running.
•Use the same fill rate (low–medium–high) each time you fill the tank.
•Allow no more than two automatic click–offs when filling.
•Have the vehicle loading and distribution the same every time.
•If your vehicle is equipped with dual fuel tanks, fill the tanks evenly
or the fuel gauge reading may fluctuate slightly until the fuel level
between the two tanks balances out and becomes equal.
Note:If your vehicle is equipped with dual fuel tanks add fuel to both
fuel tanks when refueling or engine performance may degrade.
Results are most accurate when the filling method is consistent.
Calculating Fuel Economy
Do not measure fuel economy during the first 1000 miles
(1600 kilometers) of driving; this is your engine’s break-in period. Start
measuring after driving 2000–3000 miles (3200–4800 kilometers). Also,
fuel expense, frequency of fill-ups or fuel gauge readings are not
accurate ways to measure fuel economy.
1. Fill the fuel tank completely and record the initial odometer reading.
2. Each time you fill the tank, record the amount of fuel added.
3. After at least three to five tank fill-ups, fill the fuel tank and record
the current odometer reading.
4. Subtract your initial odometer reading from the current odometer
reading.
5. Calculate fuel economy as follows:
•Standard: Divide miles traveled by gallons used.
•Metric: Multiply liters used by 100, then divide by kilometers
traveled.
