GENERAL INFORMATION
WARNING: Extended idling at high
engine speeds can produce very high
temperatures in the engine and exhaust
system, creating the risk of fire or other
damage. WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING: Do not start the engine
in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic.
Always open the garage door before you
start the engine. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
If you disconnect the battery, your vehicle
may exhibit some unusual driving
characteristics for approximately
5.0 mi
(8 km) after you reconnect it. This is
because the engine management system
must realign itself with the engine. You can
disregard any unusual driving
characteristics during this period.
The powertrain control system meets all
Canadian interference-causing equipment
standard requirements regulating the
impulse electrical field or radio noise.
When you start the engine, avoid pressing
the accelerator pedal before and during
operation. Only use the accelerator pedal
when you have difficulty starting the
engine. If your vehicle is operated in a heavy snow
storm or blowing snow conditions, the
engine air induction may become partially
clogged with snow and ice. If this occurs,
the engine may experience a significant
reduction in power output. At the earliest
opportunity, clear all the snow and ice
away from the air induction inlet.

Cold Weather Starting (Flexible
Fuel Vehicles Only)
The starting characteristics of all grades
of E85 ethanol make it unsuitable for use
when ambient temperatures fall below
0°F (-18°C). Consult your fuel distributor
for the availability of winter grade ethanol.
As the outside temperature approaches
freezing, ethanol fuel distributors should
supply winter grade ethanol, the same as
with unleaded gasoline.
If summer grade ethanol is used in cold
weather conditions, 0°F (-18°C), you may
experience increased cranking times, rough
idle or hesitation until the engine has
warmed up.
You may experience a decrease in
performance when the engine is cold when
operating on E85 ethanol.
Do not use starting fluid such as ether in
the air intake system. Such fluid could
cause immediate explosive damage to the
engine and possible personal injury.
If you should experience cold weather
starting problems on E85 ethanol, and
neither an alternative brand of E85 ethanol
nor an engine block heater is available, the
addition of unleaded gasoline to your tank
improves cold starting performance. Your
vehicle is designed to operate on E85
ethanol alone, unleaded gasoline alone, or
any mixture of the two.
If the Engine Fails to Start Using the
Preceding Instructions (Flexible Fuel
Vehicles Only)
1. Press the accelerator pedal down one-third to one-half of its travel, and
then crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speed
increases. If the engine still does not
start, repeat Step 1. Guarding Against Exhaust Fumes WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the
following:
• Open the windows at least
1 in
(2.5 cm).
• Set your climate control to outside air.
STARTING A DIESEL ENGINE -
6.7L DIESEL
Read all starting instructions carefully
before you start your vehicle.
For temperatures below
32°F (0°C), the
use of the correct grade engine oil is
essential for proper operation. Refer to
engine oil specifications for more
information. See
Engine Oil Capacity
and Specification (page 449).
Your vehicle may have a cold weather
starting strategy that prevents severe
engine damage by assisting in engine
lubrication warm-up. In extremely cold
ambient temperatures, this strategy
activates and prevents the accelerator
pedal from being used for 30 seconds after
you start your vehicle. A message appears
in the information display as your vehicle
warms up. By not allowing the accelerator
pedal to be used, the engine oil is allowed
to properly lubricate the bearings
177
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Starting and Stopping the Engine

preventing engine damage due to lack of
proper lubrication. After the 30 second
warm-up period, the accelerator pedal
becomes operational again and a message
appears informing you the vehicle is ok to
drive.
When you start the engine in extremely
cold temperatures -15°F (-26°C), we
recommend that you allow the engine to
idle for several minutes before you drive
the vehicle.
Before starting the engine check the
following:
• Make sure all occupants fasten their
seatbelt.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P).
Note: Do not press the accelerator during
starting.

Diesel Engine Fast Start Glow Plug
System
The diesel engine glow system consists of:
• Eight glow plugs, one per cylinder.
• Glow Plug Control Module.
• Engine Coolant Temperature sensor.
• Barometric pressure sensor.
• Environmental temperature sensor.
The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on, the glow plug control module
immediately energizes the glow plugs. The
glow plug control module uses the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor to determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase.

Automatic Engine Shutdown
If your vehicle is equipped with a keyless
ignition, it has a feature that automatically
shuts down the engine if it has been idling
for an extended period. The ignition also
turns off in order to save battery power.
Before the engine shuts down, a message
appears in the information display showing
a timer counting down from 30 seconds.
If you do not intervene within 30 seconds,
the engine shuts down. Another message
appears in the information display to
inform you that the engine has shut down
in order to save fuel. Start your vehicle as
you normally do.
Cold Weather Starting
WARNING: Do not use starting
fluid, for example ether, in the air intake
system. Such fluid could cause
immediate explosive damage to the
engine and possible personal injury. WARNING:
Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
We recommend that the engine block
heater be used for starting when the
temperature is -9°F (-23°C) or colder. See
Engine Block Heater
(page 182).
When operating in cold weather, you may
use Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer as needed. Switch the ignition on. Do not
start the engine until the
glow-plug indicator turns off. When the glow plug pre-heat indicator
turns off, turn the key to start. After you
start the engine, the glow plugs may
remain on for a period. If you do not start
the engine before the glow plug activation
time ends, you need to reset the glow plugs
by switching the ignition off. After the
engine starts, allow it to idle for about 15
seconds. This protects the engine. Do not
increase engine speed until the oil pressure
gauge indicates normal pressure.
Cold Weather Operation
Note:
Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Change to a lighter grade engine oil to
make starting easier under these
conditions. Refer to engine oil
specifications. See
Engine Oil Capacity
and Specification (page 449).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See
Engine Oil Capacity and
Specification (page 449).
