HYBRID ELECTRIC VEHICLEINFORMATION – FREQUENTLYASKED QUESTIONS
What should I do if the vehicle runs outof fuel and the high voltage battery isout of charge?
Refuel and start your vehicle normally.The engine will recharge the highvoltage battery.
Why does the engine sometimes startat key-on?
The vehicle's computer determines ifan engine start is required at key-on.It starts the engine when necessary forcabin heating, windshield defrost, or ifthe outside temperature is low.
Can I put E15 or E85 in my vehicle, andhow will it affect my fuel economy?
Your hybrid vehicle can use E15 (15%ethanol, 85% gasoline) fuel, but youmay notice slightly reduced fueleconomy because ethanol containsless energy per gallon than gasoline.Your hybrid vehicle is not designed touse E85 (85% ethanol).
Why does it take a long time before theengine shuts down?
There are several reasons the enginestays on for an extended amount oftime when you first start it. Onecommon reason is to make sure thatthe emissions components are warmenough to minimize tailpipe emission.As the climate gets cooler, theengine-on time is extended.
Why does my engine stay on when it isextremely cold outside?
In order to make sure that the climatecontrol system can begin heating thecabin or defrosting the windshield assoon as a driver requests it, the enginecoolant temperature has to be keptsufficiently hot. Keeping the engine onis required to maintain the correctcoolant temperature.
POWER FLOW
WHAT IS POWER FLOW
The power flow shows how power is beingused in the vehicle and also displaysreasons for engine operation.
HOW DOES POWER FLOW WORK
The power flow information foryour hybrid vehicle is availablethrough the home screen orunder Apps.
Vehicle Operational States
Power flows to or from the front and rearwheels depending on the operational stateand the drive conditions.
•Idling: The vehicle is running and in park(P). The engine and/or the high voltagebattery are on.
•Electric driving: The vehicle is runningand in drive (D) or neutral (N). The highvoltage battery provides power to thewheels.

ELECTRIC POWER STEERING
HOW DOES ELECTRIC POWERSTEERING WORK
Adaptive Learning
Adaptive learning helps correct roadirregularities and improves overall handlingand steering. It communicates with thebrake system to help operate advancedstability control and crash avoidancesystems.
Note:When the battery is disconnected ora new battery is installed, you must driveyour vehicle a short distance before thesystem relearns the strategy and reactivatesall systems.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds could also make the steeringwander or pull.
ELECTRIC POWER STEERINGPRECAUTIONS
WARNING: The electric powersteering system has diagnostic checksthat continuously monitor the system. Ifa fault is detected, a message displaysin the information display. Stop yourvehicle as soon as it is safe to do so.Switch the vehicle off. After at least 10
seconds, switch the vehicle on andwatch the information display for asteering system warning message. If asteering system warning messagereturns, have the system checked assoon as possible.
WARNING: If the system detectsan error, you may not feel a difference inthe steering, however a serious conditionmay exist. Have your vehicle checked assoon as possible. Failure to do so mayresult in loss of steering control.
Adapt your speed and driving behavioraccording to reduced steering assist.
Extreme continuous steering may increasethe effort to steer. This occurs to preventinternal overheating and damage to thesteering system. If this occurs, you will notlose the ability to steer your vehiclemanually nor will it cause damage to thesystem. Normal steering and driving allowsthe system to cool down and steeringassist returns to normal.
Note:There is no fluid reservoir to check orfill.
ELECTRIC POWER STEERINGADAPTIVE STEERING - VEHICLESWITH: ACTIVE STEERING
Electric Power-Assisted Steering (EPAS)
The adaptive steering system changes thesteering ratio with changes to vehiclespeed, optimizing the steering response inall conditions. The system also changeswhen you switch on the transmissiontow/haul feature. When you select thetow/haul button, the adaptive steeringsystem reduces vehicle sensitivity tosteering inputs at higher vehicle speeds,while maintaining the ease of parking andmaneuverability at low speeds.

2023 F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202206, DOMSteering
Note:The adaptive steering systemcontinuously monitors for faults. If thesystem detects a fault, a message appearsin the information display. If a red warningmessage displays, stop your vehicle as soonas it is safe to do so. The message couldclear if the fault is no longer present. If anadaptive steering system warning messageappears each time you start your vehicle,have the system checked as soon aspossible.
Note:The system has a locking device. Itremains mechanically locked at a fixedsteering ratio with the lock engaged. Youmay notice a click when you turn yourvehicle on or off.
Note:If your vehicle loses electrical poweror detects a fault when you are driving, thesystem shuts down and you retain a normalsteering function with a fixed steering ratio.During this time, it is possible that thesteering wheel could not be straight whenthe vehicle is driving straight ahead. Inaddition, you could notice that the steeringwheel angle required to steer your vehiclecould be different.
Note:During parking maneuvers, theadaptive steering system balances the driverworkload for various steering wheel inputsand vehicle loading conditions. Underextreme operating conditions the systemlocking device could engage. This strategyprevents overheating and permanentdamage to the adaptive steering system.Typical steering and driving maneuversallow the system to cool and return tonormal operation.
Adaptive Learning
Adaptive learning helps correct roadirregularities and improves overall handlingand steering. It communicates with thebrake system to help operate advancedstability control and crash avoidancesystems. Additionally, whenever youdisconnect the battery or install a newbattery, you must drive your vehicle a shortdistance before the system relearns thestrategy and reactivates all systems.

OFF-ROAD DRIVING
WHAT IS OFF-ROAD DRIVING
Off-road driving is driving your vehicle onunsurfaced roads or trails, made from dirt,rocks, sand and mud.
OFF-ROAD DRIVINGPRECAUTIONS - RAPTOR
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
Before going off-road driving, consult withall the appropriate government entities todetermine where you are legally allowedto operate your vehicle and what permitsor registrations are required to do so.
Inspect your vehicle before and after anyoff-road driving.
Familiarize yourself with the dimensionsof your vehicle including approach angles,breakover angles, and ground clearance.
Also familiarize yourself with the featuresof your vehicle. Some of these featuressuch as drive modes and cameras canimprove your off-road driving experience.
Secure loose objects inside your vehicleand in the cargo area.
BASIC OFF-ROAD DRIVINGTECHNIQUES - EXCLUDING:RAPTOR
Off-road Driving Hints
Before taking your vehicle off-roading, abasic vehicle inspection should be done tomake sure that the vehicle is in top workingcondition. It is always recommended thatat least two vehicles are used whileoff-roading. The buddy system helps makesure that help is close at hand should avehicle become stuck or damaged. It is alsowise to take supplies such as a first aid kit,supply of water, tow strap, cell or satellitephone with you any time an off-roadexcursion is planned.
1.Grip the steering wheel with thumbson the outside of the rim. This willreduce the risk of injury due to abruptsteering wheel motions that occurwhen negotiating rough terrain.
2.Throttle, brake and steering inputsshould be made in a smooth andcontrolled manner. Sudden inputs tothe controls can cause loss of tractionor upset the vehicle, especially whileon loose terrain or while crossingobstacles such as rocks or logs.
3.Look ahead on your route notingupcoming obstacles, or any otherfactors which may indicate a changein available traction, and adjust thevehicle speed and route accordingly.
4.When driving off-road, if the front orrear suspension is bottoming outand/or excessive contact with theskid-plates is encountered, reducevehicle speed to avoid potentialdamage to the vehicle.
5.When with other vehicles, it isrecommended that communication isused, and the lead vehicle notify othervehicles of obstacles that could causepotential vehicle damage.

WARNING: Do not remove thecoolant reservoir cap when the engine ison or the cooling system is hot. Wait 10minutes for the cooling system to cooldown. Cover the coolant reservoir capwith a thick cloth to prevent thepossibility of scalding and slowly removethe cap. Failure to follow this instructioncould result in personal injury.
WARNING: Do not add coolantwhen the vehicle is on or the coolingsystem is hot. Failure to follow thisinstruction could result in personal injury.
WARNING: Do not add coolantfurther than the MAX mark.
WARNING: Do not put coolant inthe windshield washer reservoir. Ifsprayed on the windshield, coolant couldmake it difficult to see through thewindshield.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.
Note: Do not use stop leak pellets, coolingsystem sealants, or non-specified additivesas they can cause damage to the enginecooling or heating systems. Resultingcomponent damage may not be covered bythe vehicle Warranty.
Note:Automotive fluids are notinterchangeable.
It is very important to use predilutedcoolant approved to the correctspecification in order to avoid plugging thesmall passageways in the engine coolingsystem. See Capacities andSpecifications (page 578). Do not mixdifferent colors or types of coolant in yourvehicle. Mixing of engine coolants or usingan incorrect coolant may harm the engineor cooling system components and couldvoid the vehicle Warranty.
Note:If prediluted coolant is not available,use the approved concentrated coolantdiluting it to 50/50 with deionized ordistilled water. See Capacities andSpecifications (page 578). Using water thathas not been deionized may contribute todeposit formation, corrosion and pluggingof the small cooling system passageways.
To top up the coolant level do thefollowing:
1.Unscrew the cap slowly. Any pressureescapes as you unscrew the cap.
2.Add enough prediluted coolant toreach the correct level.
Note:We do not recommend the use ofrecycled coolant.
3.Replace the coolant reservoir cap. Turnthe cap clockwise until it contacts thehard stop.
4.Check the coolant level in the coolantreservoir the next few times you driveyour vehicle. If necessary, repeat step2.
If you have to add more than 1.1 qt (1 L) ofengine coolant per month, have yourvehicle checked as soon as possible.Operating an engine with a low level ofcoolant can result in engine overheatingand possible engine damage.
In case of emergency, you can add a largeamount of water without engine coolantin order to reach a vehicle service location.Service your vehicle as soon as possible.

2023 F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202206, DOMMaintenance
Water alone, without engine coolant, cancause engine damage from corrosion,overheating or freezing.
Do not use the following as a coolantsubstitute, as they can cause enginedamage from overheating or freezing:
•Alcohol.
•Methanol.
•Brine.
•Any coolant mixed with alcohol ormethanol antifreeze.
Do not add extra inhibitors or additives tothe coolant. These can be harmful andcompromise the corrosion protection ofthe coolant.
Severe Climates
If you drive in extremely cold climates, youmay need to increase the coolantconcentration above 50%.
Note:A coolant concentration of 60%provides improved freeze point protection.Coolant concentrations above 60%decrease the overheat protectioncharacteristics of the coolant and couldcause engine damage.
If you drive in extremely hot climates, youmay need to decrease the coolantconcentration to 40%.
Note:A coolant concentration of 40%provides improved overheat protection.Coolant concentrations below 40%decrease the overheat and corrosionprotection characteristics of the coolant andcould cause engine damage.
Coolant Change
WARNING: Do not dispose ofcoolant in the household refuse or thepublic sewage system. Use an authorizedwaste disposal facility.
Change the coolant at specific mileageintervals. Refer to the scheduledmaintenance information. See NormalScheduled Maintenance (page 670).
Note:Dispose of used coolant in theappropriate manner.
Follow your community's regulations andstandards for recycling and disposing ofautomotive fluids.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarilydrive your vehicle before any incrementalcomponent damage occurs. The fail-safedistance depends on ambienttemperature, vehicle load and terrain.
How Fail-Safe Cooling Works
WARNING: If you continue to driveyour vehicle when the engine isoverheating, the engine could stopwithout warning. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle.
If the engine begins to overheat,the coolant temperature gaugemoves toward the red zone:
A warning lamp illuminates anda message may appear in theinformation display.
If the engine reaches a presetover-temperature condition, the engineautomatically switches to alternatingcylinder operation. Each disabled cylinderacts as an air pump and cools the engine.
When this occurs, your vehicle stilloperates, however:
•Engine power is limited.
•The air conditioning system turns off.
508
2023 F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202206, DOMMaintenanceE103308 E67028
You may notice a reduction in vehiclespeed caused by reduced engine power inorder to manage the engine coolanttemperature. Your vehicle may enter thismode if certain high-temperature andhigh-load conditions take place. Theamount of speed reduction depends onvehicle loading, grade and ambienttemperature. If this occurs, there is noneed to stop your vehicle. You cancontinue to drive.
The air conditioning may automaticallyturn on and off during severe operatingconditions to protect the engine fromoverheating. When the coolanttemperature decreases to the normaloperating temperature, the air conditioningturns on.
If the coolant temperature gauge movesfully into the red zone, or if the coolanttemperature warning or service enginesoon messages appear in your informationdisplay, do the following:
1.Stop your vehicle as soon as it is safeto do so. Fully apply the parking brake,shift into park (P) or neutral (N).
2.Leave the engine running until thecoolant temperature gauge needlereturns to the normal position. If thetemperature does not drop afterseveral minutes, follow the remainingsteps.
3.Switch the engine off and wait for it tocool. Check the coolant level.
4.If the coolant level is at or below theminimum mark, add prediluted coolantimmediately.
5.If the coolant level is normal, restartthe engine and continue.
ENGINE AIR FILTER
CHANGING THE ENGINE AIRFILTER
WARNING: To reduce the risk ofvehicle damage and personal burninjuries, do not start your engine with theair cleaner removed and do not removeit while the engine is running.
Change the air filter element at the properintervals. See Scheduled Maintenance(page 667).
When changing the air filter element, useonly the air filter element listed. SeeCapacities and Specifications (page578).
Note:Failure to use the correct air filterelement could result in severe enginedamage that the vehicle Warranty may notcover.
Note:When servicing the air cleaner, do notallow foreign material to enter the airinduction system. The engine is susceptibleto damage from even small particles.
