WHAT IS TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed,reduces engine power at the same time toincrease traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The traction control system turns on eachtime you switch the ignition on.
The button for the stability and tractioncontrol system is on the instrument panel.
Press and release the button to switchtraction control off. The stability controlsystem remains fully active, to switch it off,press and hold the button for a fewseconds, then release.
When you switch traction control off, amessage and an illuminated icon appearon the instrument cluster.
Press the switch again to turn the tractioncontrol system back on to normaloperation.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarketroof racks, suspension, steering system,tire construction and wheel and tire sizemay change the handling characteristicsof your vehicle and may adversely affectthe performance of the electronicstability control system. In addition,installing any stereo speakers mayinterfere with and adversely affect theelectronic stability control system.Reducing the effectiveness of theelectronic stability control system couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
WARNING: Remember that evenadvanced technology cannot defy thelaws of physics. It's always possible tolose control of a vehicle due toinappropriate driver input for theconditions. Aggressive driving on anyroad condition can cause you to losecontrol of your vehicle increasing the riskof personal injury or property damage.Activation of the electronic stabilitycontrol system is an indication that atleast some of the tires have exceededtheir ability to grip the road; this couldreduce the operator's ability to controlthe vehicle potentially resulting in a lossof vehicle control, vehicle rollover,personal injury and death.
WARNING: You are responsible forcontrolling your vehicle at all times. Thesystem is designed to be an aid and doesnot relieve you of your responsibility todrive with due care and attention. Failureto follow this instruction could result inthe loss of control of your vehicle,personal injury or death.
If a driving condition activates either thestability control or traction control you mayexperience the following conditions:
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
The stability control system has severalfeatures built into it to help you maintaincontrol of your vehicle:
Electronic Stability Control
Electronic stability control enhances yourvehicle’s ability to prevent skids or lateralslides by applying brakes to one or moreof the wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances yourvehicle’s ability to prevent rollovers bydetecting your vehicle’s roll motion andthe rate at which it changes by applyingthe brakes to one or more wheelsindividually.
Curve Control
Curve control enhances your vehicle’sability to follow the road when corneringseverely or avoiding objects in the roadway.Curve control operates by reducing enginepower and, if necessary, applying brakesto one or more of the wheels individually.

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.
