Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER 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:
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 catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. 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.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 156).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.

•
The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the SCR system leads to a diesel
exhaust fluid system fault, eventually
leading to the vehicle only operating in
idle-only mode.
• Do not dilute diesel exhaust fluid with
water or any other liquid.
• An ammonia odor may be smelled
when the cap is removed or during
refill. Refill diesel exhaust fluid in a well
ventilated area.
Typical Diesel Exhaust Fluid Usage

0–7,800 mi (0– 12,550 km)
Contaminated Diesel Exhaust
Fluid or Inoperative Selective
Catalytic Reduction System
Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality. A warning lamp illuminates and
a message appears in the
information display if the system
becomes contaminated or inoperative. Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired results
in the following actions as required by the
California Air Resources Board (CARB) and
U.S. Environmental Protection Agency
(EPA):
•
Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
replacing contaminated diesel exhaust
fluid causes the engine to enter an
idle-only condition. This only occurs
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and is indicated by
a message in the information display
indicating required actions to resume
normal operation.
Note: For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.
DIESEL PARTICULATE FILTER
Your vehicle has a diesel particulate filter.
The diesel particulate filter is an inline filter
in the exhaust system that reduces carbon
emissions by trapping exhaust particles
before they reach the tailpipe. The diesel
particulate filter looks similar to a
traditional exhaust catalyst, except larger,
and is part of the exhaust system under
your vehicle. The filter couples to a diesel
oxidation catalyst that reduces the amount
of harmful exhaust emitted from the
tailpipe. As soot gathers in the system, it
begins to restrict the filter. Periodically, you
need to clean the soot that gathers inside
the filter. You can clean the soot in two
different ways, passive regeneration and
active regeneration. Both methods occur
109
F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Engine Emission ControlE163176
Before you start operator commanded
regeneration, do the following:
•
Shift into park (P) or if you have an
RNDM selector shift into neutral (N)
and apply the parking and or air 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.
How to Start Operator Commanded
Regeneration WARNING:
Stay clear of the
exhaust tailpipe during regeneration. Hot
exhaust gases can burn you badly.
Note: You cannot use the operator
commanded 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.
Note: During the use of operator
commanded regeneration, you may observe
a light amount of white smoke. This is
normal. You may not be able to use
operator commanded
regeneration if the service engine
soon warning lamp appears in the
information display Information Display Procedure
Start your vehicle engine and when it has
reached the normal operating temperature,
press the information display control
button on the steering wheel until Exhaust

COLD WEATHER
PRECAUTIONS
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.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See Capacities and
Specifications (page 261).
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
Capacities and
Specifications (page 261).
Your vehicle is equipped with a fuel and
water separator that recirculates fuel from
the engine to help prevent fuel filter
clogging. To avoid engine fuel starvation
during cold weather operation of
32°F
(0°C) or below, we recommended that
the fuel level in your tank should not drop
below 1⁄4 full. This helps prevent air from
entering the fuel system and stalling the
engine. Your vehicle is equipped with a selective
catalyst reduction system that uses Diesel
Exhaust Fluid (DEF) to operate properly.
You need to replenish your vehicle
’s DEF
at certain intervals. When filling your
vehicle ’s DEF tank in cold weather, you
must take special care to prevent damage
to the tank. See
Selective Catalytic
Reductant System (page 105).
In cold weather below
32°F (0°C), the
engine may slowly increase to a higher idle
speed if left idling in park (P) or neutral
(N).
If you operate your vehicle in a heavy
snowstorm or blowing snow conditions,
snow and ice can clog the engine air
induction. If this occurs, the engine may
experience a significant reduction in power
output. At the earliest opportunity, clear
all the snow or ice away from inside the air
filter assembly. Remove the air cleaner
cover and the pleated paper filter, leaving
the foam filter in and remove any snow or
ice. Make sure you install the foam filter
correctly in place. Remove any debris,
snow or ice on the foam filter by brushing
the surface with soft brush. Once you have
cleared all of the debris, reinstall the air
filter and assembly.
Do not use water, solvents, or a hard brush
for cleaning the foam filter. WARNING:
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.
151
F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Driving Hints
In order to operate the engine in
temperatures of 32°F (0°C) or lower, read
the following instructions:
•
Make sure that the batteries are of
sufficient size and are fully charged.
Check other electrical components to
make sure they are in optimum
condition
• Use the proper coolant solution at the
concentration recommended
protecting the engine against damage
from freezing
• Try to keep the fuel tank full as much
as possible at the end of operation to
prevent condensation in the fuel
system
• Make sure you use proper cold weather
engine oil and that it is at its proper
level. Also, if necessary, make sure to
follow the engine oil and filter change
schedule found under the Special
operating conditions section listed in
the scheduled maintenance
information
• At temperatures of -9°F (-23°C) or
below, it is recommended that you use
an engine block heater to improve cold
engine starting
• If operating in arctic temperatures of
-20°F (-29°C)
or lower, consult your
truck dealer for information about
special cold weather equipment and
precautions
The following cold weather idling
guidelines are recommended:
• You can use Motorcraft® cetane
improvers or non-alcohol-based
cetane improvers from a reputable
manufacturer as needed.
• Maintain the engine cooling system
properly. •
Avoid shutting the engine down after
an extensive idling period. Drive your
vehicle for several miles with the
engine at normal operating
temperatures under a moderate load.
• Consider using an engine block heater.
• For extended idle times use an
approved idle speed increase device.
Winter Operating Tips for Arctic
Operation -20°F (-29°C) and
Below
The following information is a guideline
only and is not to be the only source of
possible solutions in resolving extreme
cold temperature issues.
Starting Aids WARNING:
Do not use starting
fluid, such as ether, in the air intake
system (see air filter decal). Such fluid
could cause immediate explosive
damage to the engine and possible
personal injury.
The use of the factory engine block heater
assists in engine starting in extreme cold
ambient temperatures. See
Engine Block
Heater (page 90).
Idle Control
Your vehicle may have a factory option for
a stationary elevated idle control through
dash-mounted upfitter switches that
allows the operator to elevate the idle rpm
for extended idle periods, as well as
aftermarket equipment such as PTO
operation. You must configure this feature
even if ordered from the factory. See your
authorized dealer for required upfitting.
152
F650750 (TBC) , enUSA, Edition date: 201804, Second-Printing Driving Hints
Operation in Snow and Rain
Vehicle operation in heavy snowfall or
extreme rain conditions may feed
excessive amounts of snow or water into
the air intake system. This could plug the
air filter with snow and may cause the
engine to lose power and possibly shut
down.
We recommend the following actions after
operating your vehicle up to 199 mi
(320 km) in snowfall or extreme rain:
• Snow: At the earliest opportunity, open
the hood and clear all the snow and ice
from the air filter housing inlet (do not
remove the foam filter) and reset the
air filter restriction gauge.
Note: Removal of the foam filter degrades
your vehicle performance during snow and
hot weather conditions.
• Extreme rain: The air filter dries after
about 15– 30 minutes at highway
speeds. At the earliest opportunity,
open the hood and reset the air filter
restriction gauge.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
Operation in Standing Water
Ingestion of water into the diesel engine
can result in immediate and severe
damage to the engine. If driving through
water, slow down to avoid splashing water
into the intake. If the engine stalls, and you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
