FORD SUPER DUTY 2023 Owners Manual

•Follow the recommended servicemaintenance intervals. See GeneralMaintenance Information (page 594).
•Do not store biodiesel fuel in the fueltank for more than 1 month.
•Consider changing brands or reducingbiodiesel content if you have coldtemperature fuel gelling issues or afrequently appearing LOW FUELPRESSURE message.
Use of biodiesel in concentrations greaterthan 20% can cause damage to yourvehicle, including engine and/or exhaustafter-treatment hardware (exhaustcatalyst and particulate filter) failures.Concentrations greater than 20% can alsocause fuel filter restrictions that couldresult in a lack of power or damage to fuelsystem components, including fuel pumpand fuel injector failures.
We recommend SAE 5W-40 oil for fuelswith greater than 5% biodiesel (B5). Formore information about oil changeintervals and other maintenance whenoperating on biodiesel. See SpecialOperating Conditions ScheduledMaintenance (page 603).
Look for a label on the fuel pump toconfirm the amount of biodiesel containedin diesel fuel. Ask the service stationattendant to confirm the biodiesel contentof diesel fuel, if you do not see a label onthe fuel pump.
If you plan to park or store your vehicle formore than 1 month, then you should emptyyour vehicle fuel tank of biodiesel fuel. Youshould fill the tank with a purepetroleum-based diesel fuel and run yourvehicle for a minimum of 30 minutes.
Note:Degraded or oxidized biodiesel candamage fuel system seals and plastics andcorrode steel parts.
During cold weather, if you have problemsoperating on biodiesel, you may need touse diesel fuel with lower biodieselcontent, try another brand or discontinuethe use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add anyaftermarket additives to your fuel if youuse a high-quality diesel fuel that conformsto ASTM industry specifications.Aftermarket additives can damage the fuelinjector system or engine.
Use Motorcraft® cetane booster or anequivalent cetane booster additive if yoususpect fuel has low cetane. UseMotorcraft® anti-gel and performanceimprover or an equivalent additive if thereis fuel gelling.
Do not use alcohol-based additives toimprove cetane quality, to prevent fuelgelling or any other use. The use of alcoholadditives could result in damage to the fuelinjectors and system.
Your Warranty may not cover repairsneeded to correct the effects of using anaftermarket product that does not meetour specifications in your fuel.

WHAT IS THE DIESEL
PARTICULATE FILTER
The diesel particulate filter is part of yourvehicle's emissions system and filtersharmful diesel particulates from theexhaust gas.
HOW DOES THE DIESEL
PARTICULATE FILTER WORK
The diesel particulate filter reducesemissions by trapping exhaust particlesbefore they reach the tailpipe. The systemmust periodically clean the exhaustparticles that gather inside the filter. Thisis carried out in three ways, passiveregeneration, active regeneration andmanual regeneration.
Passive Regeneration
In passive regeneration, the normalexhaust system temperature cleans thefilter by oxidizing the soot. Cleaning occursduring normal vehicle operating conditionsdue to driving patterns.
Active Regeneration
Once the diesel particulate filter is full,active regeneration raises the exhausttemperature to eliminate the particles.
When the engine control module detectsthat the diesel particulate filter is nearlyfull of particulates, and you are notoperating your vehicle in a manner to alloweffective regeneration, messages appearin the information display as a reminderfor you to drive your vehicle in order toclean the diesel particulate filter. If youdrive your vehicle in a manner to alloweffective regeneration, the informationdisplay shows a cleaning exhaust filtermessage.
DIESEL PARTICULATE FILTER
PRECAUTIONS
WARNING: Do not park or idle yourvehicle over dry leaves, dry grass or othercombustible materials. The regenerationprocess creates very high exhaust gastemperatures and the exhaust willradiate a considerable amount of heatduring and after regeneration and afteryou have switched the engine off. This isa potential fire hazard.
WARNING: When the ExhaustFilter Cleaning message appears in theinformation display, do not park nearflammable materials, vapors orstructures until filter cleaning iscomplete.
WARNING: The normal operatingtemperature of the exhaust system isvery high. Never work around or attemptto repair any part of the exhaust systemuntil it has cooled. Use special care whenworking around the diesel oxidationcatalytic converter or the dieselparticulate filter. The diesel oxidationcatalytic converter and the dieselparticulate filter heat up to very hightemperatures after only a short periodof engine operation and remain hot afteryou switch the engine off.
Note:Avoid running out of fuel.
Note: During regeneration at low speed orengine idle, you may smell a hot metallicodor and could notice a clicking metallicsound. This is due to high temperaturesreached during regeneration and is normal.
Note:Changes in the engine or exhaustsound may be heard during the regenerationprocess.
221
2023 Super Duty (TFH) Canada/United States of America, enUSA, Edition date: 202211, DOMDiesel Particulate Filter (If Equipped)

Failure to perform active or manualregeneration when instructed could resultin a clogged diesel particulate filter. If thediesel particulate filter fills beyond theregeneration threshold, your vehicledisables the ability for active and manualregeneration. This could result inirreversible damage your vehicle Warrantymay not cover.
DIESEL PARTICULATE FILTER
REQUIREMENTS
The diesel particulate filter on your vehiclerequires periodic regeneration to maintainits correct function.
If your journeys meet one of the followingconditions:
•You drive only short distances.
•You frequently switch the ignition onand off.
•Your journeys contain a high level ofacceleration and deceleration.
You must carry out occasional trips withthe following conditions to assist theregeneration process:
•Drive your vehicle in more favorableconditions, which you will find at highervehicle speeds in normal driving, on amain road or freeway for a minimumof 20 minutes. This drive may includeshort stops that will not affect theregeneration process.
•Avoid prolonged idling and observespeed limits and road conditions.
•Do not switch the ignition off.
•Select a suitable gear to ideallymaintain engine speed between 1500and 3000 RPM.

MANUAL REGENERATION
WHAT IS DIESEL PARTICULATEFILTER MANUAL REGENERATION
Diesel particulate filter manualregeneration allows you to manually startregeneration of the diesel particulate filterat idle to clean the filter.
Note:If you are not sure whether yourvehicle has this feature, contact yourauthorized dealer.
DIESEL PARTICULATE FILTERMANUAL REGENERATIONPRECAUTIONS
WARNING: Stay clear of theexhaust tailpipe during regeneration. Hotexhaust gases can burn you badly.
You may not be able to use manualregeneration if the service engine soonwarning lamp appears in the informationdisplay.
Note:During the use of manualregeneration, you may observe a lightamount of white smoke. This is normal.
DIESEL PARTICULATE FILTERMANUAL REGENERATIONREQUIREMENTS
You can use the manual regenerationfeature when a message appears in theinformation display and you are not ableto drive in a manner that allows effectiveautomatic active regeneration or if youchoose to manually start the regenerationof the diesel particulate filter while thevehicle is idle.
222
2023 Super Duty (TFH) Canada/United States of America, enUSA, Edition date: 202211, DOMDiesel Particulate Filter (If Equipped)

Before you start manual regeneration, dothe following:
•Make sure the parking brake is on.
•Shift into park (P) on stable, levelground.
•Park your vehicle outside of anystructure.
•Park your vehicle 10–15 ft (3–5 m)away from any obstructions and awayfrom materials that can easily combustor melt, for example paper, leaves,petroleum products, fuels, plastics andother dry organic material.
•Make sure there is a minimum of 1/8tank of fuel.
•Make sure all fluids are at proper levels.
DIESEL PARTICULATE FILTERMANUAL REGENERATIONLIMITATIONS
You cannot use manual regeneration untilthe diesel particulate filter load percentagehas reached 100% or Full. The dieselparticulate filter load percentagefluctuates up and down when driving yourvehicle due to active and passiveregenerations.
If your vehicle is operated with significantstationary operation, low speed drivecycles less than 25 mph (40 km/h), shortdrive cycles, drive time less than 15 minutesor the vehicle does not fully warm up,passive and active regeneration may notsufficiently clean the diesel particulatefilter system.
Aftermarket devices or modifications tothe exhaust system may reduce theeffectiveness of the exhaust system aswell as cause damage to the exhaustsystem or engine. This may also degradevehicle performance and could lead toengine damage that may not be coveredby the vehicle Warranty.
STARTING DIESEL PARTICULATEFILTER MANUAL REGENERATION
Start with your vehicle engine and when ithas reached the normal operatingtemperature, press the information displaycontrol button on the steering wheel. SeeInstrument Cluster Display (page 143).
If the diesel particulate filter is near or atsaturation, a message requestingpermission to initiate filter cleaningappears in the information display. SeeDiesel Particulate Filter – InformationMessages (page 224). Answer yes to thisprompt and then follow the next promptsregarding exhaust position required toinitiate manual regeneration. Be sure tounderstand each prompt. If you are notsure what is being asked by each prompt,contact an authorized dealer. The displayconfirms the operation has started andwhen it has finished. You can also drive toclean the filter.
When the system is at the pointof oversaturation, themalfunction indicator lampilluminates and a message appears in theinformation display. You cannot initiatefilter cleaning. You must have your vehiclechecked as soon as possible.
Once manual regeneration starts, enginespeed increases and the cooling fan speedincreases. You will hear a change in audiblesound due to engine speed and cooling fanspeed increases.
It is not necessary to open the hood on theengine compartment. Once manualregeneration completes, the engine speedreturns to normal idling. The exhaustsystem remains very hot for severalminutes even after regeneration iscomplete. Do not reposition the vehicleover materials that could burn until the

WHAT IS THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM
The selective catalytic reduction systemhelps reduce tailpipe emissions andrequires Diesel Exhaust Fluid (DEF) toconvert nitrogen oxides into nitrogen andwater.
HOW DOES THE SELECTIVE
CATALYTIC REDUCTION
SYSTEM WORK
The selective catalytic reduction systeminjects diesel exhaust fluid into the exhaustsystem to enable correct selective catalyticreduction system function.
The usage of diesel exhaust fluid hasincreased from prior model years in orderto meet more stringent emissionsrequirements. The diesel exhaust fluidusage ranges from approximately 2-6%of fuel burned (100.00 gal (378.54 L) offuel requires approximately 2.00 gal(7.57 L)to 6.00 gal (22.71 L) of dieselexhaust fluid) depending on vehicle usage.Factors that influence diesel exhaust fluidusage may include:
•Payload/Towing
•Driving Style
•Altitude
•Humidity
•Temperature
