Note:Do not increase engine speed until the oil pressure gauge
indicates normal pressure. The oil pressure gauge should indicate this
within 15 seconds after starting.
Note:Idle the engine for three to five minutes before operating with a
full load.
Note:Try to limit engine idle to 10 minutes. Excessive idling reduces
fuel economy.
Vehicles with a Manual Transmission
Note:Do not touch the accelerator pedal.
1. Fully press the clutch pedal.
2. Start the engine.
Vehicles with an Automatic Transmission
Note:Do not touch the accelerator pedal.
1. Select positionN,orP(if equipped with a Park position).
2. Fully press the brake pedal.
3. Start the engine.
Starting the Engine with the Vehicle on a Steep Grade
When starting a diesel engine when the loaded vehicle is on a grade, the
engine RPM starts to fall slightly when you engage the clutch. Do not
disengage the clutch and try to increase engine RPM as this may damage
driveline components. The engine recovers as the vehicle begins moving.
DIESEL PARTICULATE FILTER (DPF)
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 particulate filter. The DPF heats up to a high
temperature after only a short period of engine operation, and can
remain hot even after the engine is turned off. Failure to follow these
instructions may result in serious personal injury.
Your vehicle is equipped with a diesel particulate filter (DPF), as part of
the after-treatment exhaust system, to trap soot and other large particles
produced by the engine combustion process. You must periodically
reduce the soot that accumulates in the filter to prevent excessive
exhaust restriction. The engine and after-treatment system generally
perform the soot reduction process, also known as “filter regeneration,”
automatically.

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.

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.

•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.
