2019 FORD F-450 maintenance

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
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 306).
• 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.

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system may allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are: 1. Your vehicle has run out of fuel
—the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 188).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration. If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.

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
shows a cleaning exhaust filter message,
which is the normal regeneration process.
You can also choose operator commanded
regeneration to clean the exhaust system
at this point. See Information Messages
(page
128).
If you are not able to drive in a manner that
allows effective automatic active
regeneration or you choose to perform
regeneration of the diesel particulate filter
while at idle, then operator commanded
regeneration would need to be performed.
Operator Commanded Regeneration
(If Equipped)
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than
25 mph (40 km/h), short
drive cycles, a drive time is less than 10 -
15 minutes or the vehicle does not fully
warm up, passive and active regeneration
may not sufficiently clean the diesel
202
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201804, Fourth-Printing Engine Emission Control

How to Interrupt or Cancel Operator
Commanded Regeneration
If you need to cancel the operator
commanded regeneration, pressing the
brake, accelerator or switching the engine
off stops the procedure. Depending on the
amount of time you allowed the operator
commanded regeneration to operate, soot
may not have had sufficient time to be fully
eliminated, but the exhaust system and
exhaust gas may still be hot. If you shut
your vehicle off during operator
commanded regeneration, you may notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal.
Filter Service and Maintenance
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be replaced
with a new or remanufactured part at
approximately 250,000 mi (400,000 km).
Actual mileage varies depending on engine
and vehicle operating conditions.
If filter service is required, the
engine control system warning
lamp illuminates in the
information display. If there are any issues with the
diesel particulate filter system,
the engine control system
warning lamp and a service
engine soon warning lamp
illuminate to inform you that
your vehicle requires service. Have your
vehicle checked as soon as possible. Resonator and Tailpipe Assembly
Maintenance
Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty.

If Shift Delayed Pull Forward appears in
the information display, transfer case gear
tooth blockage is present. To alleviate this
condition, place the transmission in a
forward gear, move the vehicle forward
approximately
5 ft (1.5 m), and shift the
transmission back to neutral to allow the
transfer case to complete the range shift.
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 be equipped 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.

Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty. For this reason,
we strongly recommend that you do not
make modifications such as adding or
removing parts (i.e. lift kits or stabilizer
bars) or by using replacement parts not
equivalent to the original factory
equipment.
We recommend that you use caution when
your vehicle has either a high load or device
(i.e. ladder or luggage racks). Any
modifications to your vehicle that raise the
center of gravity may cause your vehicle
to roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly
may void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely
affect you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off road usage.
