fuel FORD F-450 2019 Workshop Manual

•
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.
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 128).

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201804, Fourth-Printing Engine Emission Control

particulate filter system. Operator
commanded regeneration allows you to
manually start regeneration of the diesel
particulate filter at idle to clean the filter.
If you are not sure whether your vehicle has
this feature, contact an authorized dealer.
When to Carry Out Operator Commanded
Regeneration
You can use the operator commanded
regeneration feature when a message
appears in the information display and you
are not able to drive in a manner that
allows effective automatic active
regeneration or if you choose to manually
start the regeneration of the diesel
particulate filter manually while the vehicle
is idle. See Information Messages (page
128).
Operator Commanded Regeneration
Precautions and Safe Exhaust Position 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. WARNING:
Stay clear of the
exhaust tailpipe during regeneration. Hot
exhaust gases can burn you badly.
Make sure that the louvers located at the
tip of the exhaust are clear of any
obstructions as they are used to introduce
fresh air into the tailpipe to cool the
exhaust gases as they leave the exhaust
system. Before you start operator commanded
regeneration, do the following:
•
Shift into park (P) and apply the
parking 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

Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.
Brake-Shift Interlock WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. Note:
Do not drive your vehicle until you
verify that the brake lamps are working.
Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from moving from park (P)
when the ignition is on and the brake pedal
is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition is on
and the brake pedal pressed, a malfunction
may have occurred. It is possible that a
fuse has blown or your vehicle ’s brake
lamps are not operating properly. See
Fuse Specification Chart
(page 318).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):
1. Apply the parking brake. Switch the ignition key to 1 - off, then remove the
key.
2. Move the steering column to the full down and full rearward position,
toward the driver seat.
3. Remove the gearshift lever boot.

Note:
In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE
SPEED appears in the information display.
The first thing to do is slow your vehicle
down, then pull safely to the side of the
road and check for proper tongue load and
trailer load distribution. See
Load
Carrying (page 266).
RECOMMENDED TOWING
WEIGHTS WARNING:
You must use
the heavy-duty drawbar pin
supplied with your vehicle when
using the heavy-duty hitch.
Failure to follow this instruction
could result in the loss of control
of your vehicle, personal injury or
death.
Note: Vehicles with a heavy-duty
hitch must use the drawbar pin
stamped 21,000 LBS. You can
obtain a replacement drawbar pin
at your authorized dealer. Note:
Make sure to take into
consideration trailer frontal area.
Do not exceed 60 ft 2
(5.6 m 2
) trailer
frontal area for conventional
trailers. Do not exceed 75 ft 2
(6.9
m 2
) trailer frontal area for fifth
wheel and gooseneck trailers.
Note: Exceeding this limitation
may significantly reduce the
performance of your towing
vehicle. Selecting a trailer with a
low aerodynamic drag and rounded
front design helps optimize
performance and fuel economy.
Note: For high altitude operation,
reduce the gross combined weight
by 2% per 1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point.
Note: Certain states require
electric trailer brakes for trailers
over a specified weight. Be sure to
check state regulations for this
specified weight. The maximum
trailer weights listed may be limited
to this specified weight, as your
vehicle's electrical system may not
include the wiring connector
needed to use electric trailer
brakes.
Your vehicle may tow a trailer
provided the maximum trailer
weight is less than or equal to the
maximum trailer weight
calculated using the formula
following the chart.
