HOW DOES FOUR-WHEEL
DRIVE WORK
Using the 1-Speed Automatic Four-Wheel Drive System
The 1-speed automatic four-wheel drivesystem utilizes an electronically controlledon-demand 1-speed transfer case. Thissystem monitors various vehicle sensoryinputs to provide an increased level ofperformance. This system offers the drivertwo-wheel drive high, four-wheel driveauto and four-wheel drive high as availablemodes of operation via the selectable drivemode switch. When you select four-wheeldrive auto the system continuously variespower to the front wheels for optimumperformance for all on-road conditions.When you select four-wheel drive high thesystem provides power to the front andrear wheels for use in off-road or slipperyconditions such as deep snow, sand ormud. There is further information on drivingin unique driving conditions. See DrivingHints (page 389).
Using the 2-Speed AutomaticFour-Wheel Drive System (If Equipped)
The 2-speed automatic four-wheel drivesystem utilizes an electronically controlledon-demand 2-speed transfer case. Thissystem monitors various vehicle sensoryinputs to provide an increased level ofperformance. This system offers the drivertwo-wheel drive high, four-wheel driveauto, four-wheel drive high, and four-wheeldrive low as available modes of operation.When you select four-wheel drive auto thesystem continuously varies power to thefront wheels for optimum performance forall on-road conditions. When you selecteither four-wheel drive high or four-wheeldrive low with the appropriate drive modes,the four-wheel drive system provideselectronically locked power to the frontand rear wheels for use in off-road or
slippery conditions such as deep snow,sand or mud. Selecting four-wheel drivelow also provides additional gearing forincreased torque multiplication forconditions like deep sand, snow, steepslopes, or pulling heavy objects. SeeSelecting a Four-Wheel Drive Mode(page 220).Additionally, the system iscapable of recreational flat towing byputting the transfer case into neutral (N).See Recreationally Towing YourVehicle (page 400).

FOUR-WHEEL DRIVE
PRECAUTIONS
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheeldrive vehicle may accelerate better thana two-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always driveat a safe speed.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle could behigher to allow it to travel over roughterrain without getting stuck or damagingunderbody components. The differencesthat make your vehicle so versatile also

FOUR-WHEEL DRIVE AUTO
Four-wheel drive auto provideselectronically controlled four-wheel drivepower to both the front and rear wheels,as required, for increased traction in varyingon-road conditions. The four-wheel driveauto tuning varies based on selected DriveMode. See Selecting a Drive Mode (page303).
Note:Four-wheel drive auto can turn on oroff automatically based on Drive Modeselection. See Selecting a Drive Mode(page 303).
FOUR-WHEEL DRIVE HIGH (If Equipped)
Four-wheel drive high provideselectronically locked four-wheel drivepower to both the front and rear wheelsfor use in off-road or winter conditionssuch as deep snow, sand or mud. Thismode is not for use on dry pavement.
Note:Four-wheel drive high can turn on oroff automatically based on Drive Modeselection. See Selecting a Drive Mode(page 303).
FOUR-WHEEL DRIVE LOW (If Equipped)
Four-wheel drive low provideselectronically locked four-wheel drivepower to both the front and rear wheelsfor use on low traction surfaces, but doesso with additional gearing for increasedtorque multiplication. This mode is only foroff-road conditions such as deep sand,steep slopes, or pulling heavy objects.
Note:Four-wheel drive low can turn on oroff automatically based on drive modeselection. See Selecting a Drive Mode(page 303).

FOUR-WHEEL DRIVE DRIVING
HINTS
DRIVING IN SAND
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowlyand avoid excessive wheel slip.
When driving at slow speeds in deep sandunder high outside temperatures, use a lowgear when possible. Low gear operationcan maximize the engine and transmissioncooling capability.

EVASIVE STEERING ASSIST (IF
EQUIPPED)
WHAT IS EVASIVE STEERINGASSIST
If your vehicle is rapidly approaching a roaduser, evasive steering assist helps you steeraround the road user.
After you turn the steering wheel in anattempt to avoid a crash with the roaduser, the system applies additional steeringtorque to help you steer around the roaduser. After you pass the road user, thesystem applies steering torque when youturn the steering wheel to steer back intothe lane. The system deactivates after youfully pass the road user.
Note:Road users are defined aspedestrians or bicyclists in your vehicle'spath or another stationary vehicle in thesame lane or a vehicle traveling in the samelane in the same direction as you. SeePre-Collision Assist Precautions (page328).
EVASIVE STEERING ASSISTLIMITATIONS
Evasive steering assist only activates whenall the following occur:
•Automatic emergency braking andevasive steering assist are on.
•The system detects a road user aheadand starts to apply the brakes.
•You significantly turn the steeringwheel to steer around a road user.
Note:Evasive steering assist does notautomatically steer around a road user. Ifyou do not turn the steering wheel, evasivesteering assist does not activate.
Note:Evasive steering assist does notactivate if the distance to the road userahead is too small and the system cannotavoid a crash.

HOW DOES TRAILER SWAY
CONTROL WORK
The system applies the brakes to theindividual wheels and reduces enginetorque to aid vehicle stability.
If the trailer begins to sway, the stabilitycontrol lamp flashes and the messageTrailer Sway Reduce Speed appears inthe information display.
Stop your vehicle as soon as it is safe todo so. Check the vertical weight on thetow ball and trailer load distribution.
TRAILER SWAY CONTROL
PRECAUTIONS
WARNING: Turning off trailer swaycontrol increases the risk of loss ofvehicle control, serious injury or death.Ford does not recommend disabling thisfeature except in situations where speedreduction may be detrimental (such ashill climbing), the driver has significanttrailer towing experience, and can controltrailer sway and maintain safe operation.
Note:This feature only activates whensignificant trailer sway occurs.
Note:This feature does not prevent trailersway, but reduces it once it begins.
Note:This feature cannot stop all trailersfrom swaying.
Note:In some cases, if vehicle speed is toohigh, the system may activate multipletimes, gradually reducing vehicle speed.
SWITCHING TRAILER SWAY
CONTROL ON AND OFF
1.Press Features on the touchscreen.
2.Press Towing.
3.Switch Trailer Sway Control on or off.
The system turns on each time you startyour vehicle.

WHEEL NUTS
WARNING: When you install awheel, always remove any corrosion, dirtor foreign materials present on themounting surfaces of the wheel or thesurface of the wheel hub, brake drum orbrake disc that contacts the wheel. Makesure to secure any fasteners that attachthe rotor to the hub so they do notinterfere with the mounting surfaces ofthe wheel. Installing wheels withoutcorrect metal-to-metal contact at thewheel mounting surfaces can cause thewheel nuts to loosen and the wheel tocome off while your vehicle is in motion,resulting in loss of vehicle control,personal injury or death.
