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. WARNING: Do not allow people or
animals in truck beds that have
modifications, such as bed covers or
slide-in campers, when the engine is
running. Exhaust fumes are toxic. Failure
to follow this instruction could result in
personal injury or death.
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 322).
• 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: Your vehicle warranty does not cover
resulting component damage.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.

becomes limited to engine idle only once
stopped. In these conditions, be cautious
where you stop your vehicle because you
may not be able to drive long distances
or maintain highway speeds until you
refill or replace the diesel exhaust fluid.
WARNING: Tampering with or
disabling the selective catalytic
reduction system results in severe
vehicle performance limitation including
eventual speed limiting to
5 mph
(8 km/h).
The information display shows a series of
messages about the amount of diesel
exhaust fluid available. A systems check
displays messages indicating the amount
of diesel exhaust fluid available or displays
a warning message indicating the
approximate distance remaining as the
fluid in the diesel exhaust fluid tank nears
empty. See
Information Messages
(page 123). As the diesel exhaust fluid level
nears empty, the warning
symbol displays and a series of
tones and messages starting at
500 mi
(800 km) remaining before diesel exhaust
fluid is depleted. The warning symbol and
messages continue until you refill the
diesel exhaust fluid tank. Continued driving without refilling results
in the following actions as required by the
California Air Resources Board (CARB) and
the 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
refilling the diesel exhaust fluid tank
causes the engine to enter an idle-only
condition. This only occurs upon vehicle
refueling or at an extended idle. A
message indicates the required actions
to resume normal operation. It is
required to add a minimum of
1.0 gal
(3.8 L) of diesel exhaust fluid to the
tank to exit the idle-only condition, but
your vehicle is still in the speed-limiting
mode until you refill the tank
completely.
Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you refill the diesel exhaust
fluid tank.
Note: When filling the diesel exhaust fluid
tank from empty, there may be a short delay
before detecting the increased level of fluid.
The increased level detection must occur
before your vehicle returns to full power.
Diesel Exhaust Fluid Guidelines
and Information
• Use only diesel exhaust fluid that
carries the American Petroleum
Institute (API) certified diesel exhaust
fluid trademark or ISO 22241.
• Do not put diesel exhaust fluid in the
diesel fuel tank.
• Do not overfill the diesel exhaust fluid
tank.
• Diesel exhaust fluid is corrosive.
• Do not re-use the diesel exhaust fluid
container once it is emptied.

•
Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23°F (-5°C) and 68°F (20°C).
• Diesel exhaust fluid freezes below 12°F
(-11°C)
.
• Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.
• Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.
• 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
When Using the Power Take Off (PTO) Continuous PTO use—Minimal PTO use
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
The filter forms part of the emissions
reduction system on your vehicle. It filters
harmful diesel particulates (soot) from the
exhaust gas.
Regeneration WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function. Your vehicle will carry
out this process automatically. If your journeys meet one of the following
conditions:
•
You drive only short distances.
• You frequently switch the ignition on
and off.
• Your journeys contain a high level of
acceleration and deceleration.
You must carry out occasional trips with
the following conditions to assist the
regeneration process:
• Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.
• Avoid prolonged idling and always
observe speed limits and road
conditions.
• Do not switch the ignition off.
• Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.
Oxidation Catalytic Converter and
Diesel Particulate Filter System
(If
Equipped) 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 oxidation
catalytic converter or the diesel
particulate filter. The diesel oxidation
catalytic converter and the diesel
particulate filter heat up to very high
temperatures after only a short period
of engine operation and remain hot after
you switch the engine off.
202
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201909, Second-Printing Engine Emission Control

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 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. The system must periodically
clean the soot that gathers inside the filter.
This is carried out in two ways, passive
regeneration and active regeneration. Both
methods occur automatically and require
no actions from the driver. During either
one of these regeneration methods, you
may notice a change in exhaust tone. At
certain times, the information display
shows various messages related to the
diesel particulate filter. See Information
Messages (page 123).
Diesel Particulate Filter Maintenance
You must properly maintain your vehicle's
diesel particulate filter in order for it to
function properly.
Do not disregard maintenance messages
that appear in the information display.
Failure to follow the instructions of an
information message may degrade vehicle
performance and could lead to engine
damage that may not be covered by the
vehicle Warranty.
Failure to perform active or operator
commanded regeneration when instructed
could result in a clogged diesel particulate
filter. If the diesel particulate filter fills
beyond the regeneration threshold, your
vehicle disables the ability for active and
operator commanded regeneration. This
could result in irreversible damage to the
diesel particulate filter requiring
replacement that may not be covered by
the vehicle Warranty. Passive Regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter by oxidizing
the soot. Cleaning automatically occurs
during normal vehicle operating conditions
due to driving patterns.
Active Regeneration
Once the diesel particulate filter is full of
exhaust particles, the engine control
module commands the exhaust system to
clean the filter through active regeneration.
Active regeneration requires the engine
computer to raise the exhaust temperature
to eliminate the particles. During cleaning,
the particles convert to harmless gasses.
Once cleaned the diesel particulate filter
continues trapping exhaust particles.
The regeneration process operates more
efficiently when you drive your vehicle at
a constant speed above 30 mph
(48 km/h) and at a steady engine speed
for approximately 20 minutes. The
frequency and duration of regeneration
fluctuates by how you drive your vehicle,
outside air temperature and altitude. For
most driving, regeneration frequency varies
from 100–500 mi (160–805 km) between
occurrences and each occurrence lasts
9– 35 minutes. You can usually reduce the
duration of regeneration if you maintain a
constant speed above 30 mph (48 km/h).
When the engine control module detects
that the diesel particulate filter is nearly
full of particulates and you are not
operating your vehicle in a manner to allow
effective automatic regeneration,
messages appear in the information
display as a reminder for you to drive your
vehicle in order to clean the diesel
particulate filter. If you drive your vehicle
in a manner to allow effective automatic
regeneration, the information display

If Your Vehicle Gets Stuck in Mud
or Snow
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission could occur.
Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires could occur, or the
engine could overheat.
If your vehicle is stuck in mud or snow, you
can rock it out by shifting between forward
and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the
accelerator in each gear.
POWER TAKE-OFF (IF EQUIPPED)
Note: Use of auxiliary equipment that
exceeds the maximum Power Take-Off
(PTO) load specified in our Truck Body
Builders Layout Book can adversely affect
the performance of the powertrain system.
Refer to the Body Builders Layout Book for
instructions about the appropriate
installation of additional equipment.
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation. Split Shaft Capability
(If Equipped)
Our Super Duty vehicles are approved for
use as a stationary, including split shaft
capability with 6.7L diesel only, or mobile
power source, within limits and operating
guidelines detailed in our Truck Body
Builders Layout Book. For additional

Operating 4WD Vehicles with
Spare or Mismatched Tires
On four-wheel drive vehicles, the size of
the spare tire can affect the 4X4 system.
If there is a significant difference between
the size of the spare tire and the remaining
tires, you may have limited four-wheel
drive functionality.
When driving with the full-size, dissimilar
spare wheel and tire assembly,
recommend that you do not:
• Exceed
50 mph (80 km/h) with a 4WD
mode turned on.
• Turn on a 4WD mode unless the
vehicle is stationary.
• Use a 4WD mode on dry pavement.
When driving with the full-size, dissimilar
spare wheel and tire assembly, you may
have limited 4WD functionality, especially
when driving in a mechanically locked 4WD
mode. You may experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode.
Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.

How Your Vehicle Differs from
Other Vehicles
WARNING: Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps.
You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning. Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may come with a front
air dam that can become damaged (due to
reduced ground clearance) when taking your
vehicle off-road. This air dam can be taken
off by removing 15 bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.
Power is supplied to all four wheels
through a transfer case. On four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.
Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power the
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.
