BRAKE PRECAUTIONS
Wet brakes result in reduced brakingefficiency. Gently press the brake pedal afew times when leaving a car wash ordriving from standing water to dry thebrakes.
Note:Depending on applicable laws andregulations in the country where your vehiclewas originally built, the stoplamps couldflash during heavy braking. The hazardwarning flashers could also turn on whenyour vehicle comes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEMLIMITATIONS
The anti-lock braking system does noteliminate the risk of crash when:
•You drive too closely to the vehicle infront of you.
•Your vehicle is hydroplaning.
•You take corners too fast.
•The road surface is poor.
Note: If the system activates, the brakepedal could pulse and travel further.Maintain pressure on the brake pedal.
BRAKE OVER ACCELERATOR
In the event the accelerator pedalbecomes stuck or entrapped, apply steadyand firm pressure to the brake pedal toslow the vehicle and reduce engine power.If you experience this condition, apply thebrakes and bring your vehicle to a safestop. Move the transmission to park (P),switch the engine off and apply the parkingbrake. Inspect the accelerator pedal forany interference. If none are found and thecondition persists, have your vehicle towedto the nearest authorized dealer.

CHECKING THE BRAKE FLUID
WARNING: Do not use any fluidother than the recommended brake fluidas this will reduce brake efficiency. Useof incorrect fluid could result in the lossof vehicle control, serious personal injuryor death.
WARNING: Only use brake fluidfrom a sealed container. Contaminationwith dirt, water, petroleum products orother materials may result in brakesystem damage or failure. Failure toadhere to this warning could result in theloss of vehicle control, serious personalinjury or death.
WARNING: Do not allow the fluidto touch your skin or eyes. If thishappens, rinse the affected areasimmediately with plenty of water andcontact your physician.

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 system turns on each time you switchthe ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Switching the System Off
The switch for the stability andtraction control system is on theinstrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Note:When you switch traction control off,stability control remains fully active.
Note:When you place your vehicle intofour-wheel drive low (4L), the tractioncontrol disables. Traction control resumeswhen you put your vehicle back intotwo-wheel drive or four-wheel drive high(4H).
Note:For additional information on thetraction and stability control systems. SeeStability Control (page 219).

•The stability and traction control lightilluminates steadily.
•The stability control and tractioncontrol systems do not enhance yourvehicle's ability to maintain traction ofthe wheels.
If a driving condition activates either thestability control or the traction controlsystem you may experience the followingconditions
•The stability and traction control lightflashes.
•Your vehicle slows down.
•Reduced engine power.
•A vibration in the brake pedal.
•The brake pedal is stiffer than usual.
•If the driving condition is severe andyour foot is not on the brake, the brakepedal may move as the system applieshigher brake force.

•The engine is switched off.
•You switch out of four-wheel drive low(4L) or four-wheel drive high (4H).
•You select a drive mode that does notallow the stabilizer bar to disconnect.
Note:The stabilizer bar can be reconnectedat any time. It is not necessary for thevehicle to be on a level surface as thestabilizer bar self-aligns.

WHAT IS G.O.A.T. MODE
CONTROL
Your vehicle has several goes overany-type of terrain (G.O.A.T.) modes thatyou can select for different drivingconditions. Depending on the mode thatyou select, the system adjusts variousvehicle settings.
HOW DOES G.O.A.T. MODE
CONTROL WORK
Each selectable mode changes variouselectronic and mechanical settings withinyour vehicle to tailor its performance anddriving characteristics to on-road oroff-road driving conditions. The systemmay alter steering feel and effort, tractioncontrol, stability control, chassis controls,powertrain response, transmission shiftpoints, four-wheel driveline setting,exhaust noise level and suspensiondampening to predetermined settings,depending upon the mode that you select.
The system reverts to the normal modeeach time you start your vehicle. At startupthe system also displays a prompt on theinstrument cluster display that gives youthe option to return to the previouslyselected drive mode during the last ignitioncycle. If you select yes, the system returnsto the last selected drive mode and thedefault driveline settings associated withthat mode. If you select no or do not makea selection within a short time, the systemremains in normal mode and the drivelinesettings remain the same as selected inthe prior ignition cycle.
Note:Your vehicle has diagnostic checksthat continuously monitor all systems forproper operation. If a mode is unavailabledue to a system fault, your vehicle defaultsto normal mode and the driveline remainsin the four-wheel drive setting that you lastselected prior to the system fault.

Certain states require functioning trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight.
Ford Motor Company recommendsseparate functioning brake systems fortrailers weighing more than 1,500 lb(680 kg) when loaded.
TOWING A TRAILER
LIMITATIONS
The vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Note:Your vehicle could havereduced performance whenoperating at high altitudes andwhen heavily loaded or towing a
trailer. When driving at elevation,to match driving performance asperceived at sea level, reduce grossvehicle weight and grosscombination weight by 2% per1,000 ft (300 m) elevation.
LOADING YOUR TRAILER
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight. Thetrailer tongue weight shouldnever exceed 10% of themaximum towing capacity.
•Select a ball mount with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
TRAILER TOWING HINTS -
MANUAL TRANSMISSION
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Periodicallyinspect these components during and afterany towing operation.
When driving with a trailer or payload, aslight takeoff vibration or shudder may befelt due to the increased payload weight.
Your vehicle may have a temporary orconventional spare tire. A temporary sparetire is different in diameter or width, treadtype, or from a different manufacturer thanthe road tires on your vehicle. Consultinformation on the tire label or SafetyCompliance label for limitations whenusing.
