2022 FORD F-450 Owners Manual

Before you start manual 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.
DIESEL PARTICULATE FILTER
MANUAL REGENERATION
LIMITATIONS
You cannot use manual 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.
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than
25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system.
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. STARTING DIESEL PARTICULATE
FILTER MANUAL REGENERATION
Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See
Instrument Cluster Display
(page 141).
If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See
Diesel Particulate Filter – Information
Messages
(page 215). Answer yes to this
prompt and then follow the next prompts
regarding exhaust position required to
initiate manual regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished. You can also drive to
clean the filter. When the system is at the point
of oversaturation, the service
engine warning lamp illuminates
and a message appears in the information
display. You cannot initiate filter cleaning.
You must have your vehicle checked as
soon as possible.
Once manual regeneration starts, engine
speed increases to approximately 1600
rpm and the cooling fan speed increases.
You will hear a change in audible sound
due to engine speed and cooling fan speed
increases.
It is not necessary to open the hood on the
engine compartment. Once manual
regeneration completes, the engine speed
returns to normal idling. The exhaust
system remains very hot for several
minutes even after regeneration is
complete. Do not reposition the vehicle
over materials that could burn until the
214

exhaust system has had sufficient time to
cool. Depending on the amount of soot
collected by the diesel particulate filter,
ambient temperature and altitude, manual
regeneration lasts approximately 30
minutes.

WHAT IS THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM
The selective catalytic reduction system
helps reduce emission levels of oxides of
nitrogen from the exhaust system.
HOW DOES THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM WORK
The selective catalytic reduction system
injects diesel exhaust fluid into the exhaust
system to enable correct selective catalytic
reduction system function.
SELECTIVE CATALYTIC
REDUCTION SYSTEM
PRECAUTIONS
WARNING: Keep diesel exhaust
fluid out of reach of children. Avoid
contact with skin, eyes or clothing. In
case of contact with your eyes, flush
immediately with water and get prompt
medical attention. In case of contact
with your skin, clean immediately with
soap and water. If you swallow any
diesel exhaust fluid, drink plenty of
water, call a physician immediately. WARNING:
Only refill the diesel
exhaust fluid tank in a well ventilated
area. When you remove the diesel
exhaust fluid tank filler cap or a diesel
exhaust fluid container cap, ammonia
vapors may escape. Ammonia vapors
can be irritating to skin, eyes and mucous
membranes. Inhaling ammonia vapors
can cause burning to the eyes, throat and
nose and cause coughing and watery
eyes. WARNING:
Diesel exhaust fluid
must be refilled when low or replaced
when contaminated or your vehicle
speed becomes limited to
50 mph
(80 km/h). In these conditions, drive with
caution and refill diesel exhaust fluid
immediately. If the diesel exhaust fluid
becomes empty or contaminated and
fluid is not replaced, your vehicle
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).
Note: Do not put diesel exhaust fluid in the
fuel tank. This can cause damage that your
vehicle Warranty may not cover.
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.

2022 Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202103, First-Printing Selective Catalytic Reduction System

Driving without refilling, replacing
contaminated 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 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 or 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. 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 vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you refill the diesel exhaust fluid tank
or repair the contaminated system. If the
system is contaminated or inoperative, have
your vehicle checked as soon as possible. SELECTIVE CATALYTIC
REDUCTION SYSTEM
REQUIREMENTS Only use diesel exhaust fluid that is
certified by the American Petroleum
Institute (API).
You can purchase diesel exhaust fluid at
an authorized dealer, or contact roadside
assistance for help in finding a retailer that
sells diesel exhaust fluid.
Note:
Non-certified diesel exhaust fluid use
can cause damage that your Warranty may
not cover
SELECTIVE CATALYTIC
REDUCTION SYSTEM
GUIDELINES
• Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.
• In order for the system to operate
correctly you must maintain the diesel
exhaust fluid level.
• Do not overfill the diesel exhaust fluid
tank.
• Diesel exhaust fluid is corrosive.
218

•
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.
• 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.
• Do not re-use the diesel exhaust fluid
container once it is emptied.
• Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23–68°F (-5– 20°C).
• The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the selective catalytic reduction
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. FILLING THE SELECTIVE

TANK IN COLD WEATHER
Diesel exhaust fluid may freeze if the
ambient temperature is below 12°F (-11°C).
Your vehicle has a preheating system
which allows diesel exhaust fluid to
operate below
12°F (-11°C). If you do not
use your vehicle for an extended period
when the ambient temperature is below
12°F (-11°C)
, the fluid in the tank may
freeze. If the tank is overfilled and the fluid
freezes it may cause damage that your
Warranty will not cover.
