WHAT IS HILL DESCENT
CONTROL
Hill descent control allows the driver to setand maintain vehicle speed whiledescending steep slopes in various surfaceconditions.
HOW DOES HILL DESCENT
CONTROL WORK
Hill descent control can maintain vehiclespeeds on downhill slopes between2–20 mph (3–32 km/h). Above 20 mph(32 km/h), the system remains on but thedescent speed cannot be set ormaintained.
Note:The system does not function below2 mph (3 km/h).
The system requires a cool down intervalafter a period of sustained use. Hill descentcontrol provides a warning in the messagecenter and a tone sounds when the systemis about to disengage for cooling. At thistime, manually apply the brakes as neededto maintain descent speed.
Note:The amount of time that the systemcan remain active before cooling varies withconditions.
HILL DESCENT CONTROL
PRECAUTIONS
WARNING: The system does notcontrol speed in low traction conditionsor extremely steep slopes. The systemis designed to be an aid and does notrelieve you of your responsibility to drivewith due care and attention. Failure tofollow this instruction could result inpersonal injury.
WARNING: Hill descent controlcannot control descent in all surfaceconditions and circumstances, such asice or extremely steep grades. Hilldescent control is a driver assist systemand cannot substitute for good judgmentby the driver. Failure to do so may resultin loss of vehicle control, crash or seriousinjury.
WARNING: The system does notreplace the parking brake. When youleave your vehicle, always apply theparking brake and shift the transmissioninto park (P) for automatic transmissionor first gear for manual transmission.

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.
