HOW DOES STABILITY CONTROL
WORK
WARNING: Vehicle modificationsinvolving braking system, aftermarket roofracks, suspension, steering system, tireconstruction and wheel and tire size maychange the handling characteristics of yourvehicle and may adversely affect theperformance of the electronic stabilitycontrol system. In addition, installing anystereo speakers may interfere with andadversely affect the electronic stabilitycontrol system. Reducing the effectivenessof the electronic stability control systemcould lead to an increased risk of loss ofvehicle control, vehicle rollover, personalinjury and death.
WARNING: Remember that evenadvanced technology cannot defy the lawsof physics. It's always possible to losecontrol of a vehicle due to inappropriatedriver input for the conditions. Aggressivedriving on any road condition can causeyou to lose control of your vehicle
increasing the risk of personal injury orproperty damage. Activation of theelectronic stability control system is anindication that at least some of the tireshave exceeded their ability to grip theroad; this could reduce the operator'sability to control the vehicle potentiallyresulting in a loss of vehicle control, vehiclerollover, 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 in theloss of control of your vehicle, personalinjury 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 more ofthe wheels individually and, if necessary,reducing engine power.
Roll Stability Control
Roll stability control enhances your vehicle’sability to prevent rollovers by detecting yourvehicle’s roll motion and the rate at which itchanges by applying the brakes to one ormore wheels individually.
Curve Control
Curve control enhances your vehicle’s abilityto follow the road when cornering severelyor avoiding objects in the roadway. Curvecontrol operates by reducing engine powerand, if necessary, applying brakes to one ormore of the wheels individually.

The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combined weightrating.
Certain states require functioning trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight.
Ford Motor Company recommends separatefunctioning brake systems for trailersweighing more than 1,500 lb (680 kg) whenloaded.
TOWING A TRAILER LIMITATIONS
The vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Note:Your vehicle could have reducedperformance when operating at highaltitudes and when heavily loaded ortowing a trailer. When driving atelevation, to match driving performanceas perceived at sea level, reduce grossvehicle weight and gross combinationweight by 2% per 1,000 ft (300 m)elevation.
LOADING YOUR TRAILER
To help minimize how trailer movementaffects your vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items centeredbetween the left and right side trailertires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight. The trailertongue weight should never exceed10% of the maximum towing capacity.
•Select a ball mount with the correctrise or drop. When both the loadedvehicle and trailer are connected, thetrailer frame should be level, orslightly angled down toward yourvehicle, when viewed from the side.
TRAILER TOWING HINTS
Towing a trailer places an extra load on yourvehicle's engine, transmission, axle, brakes,tires and suspension. Periodically inspectthese components during and after anytowing operation.
When driving with a trailer or payload, a slighttakeoff vibration or shudder may be presentdue to the increased payload weight.

TRAILER BACKUP ASSISTANCE –FREQUENTLY ASKED QUESTIONS
Why does the trailer not reverse straight?
Verify the sticker is correctly applied.Other factors such as the hitchconnection, road camber, road slopeand trailer suspension could influencehow straight the system can reverse thetrailer when the control knob is notturned. You can compensate for thetrailer drifting to the right or left byslowly turning the knob until the traileris following your desired path andholding the knob in that position. Checkthat the correct trailer is selected in thetouchscreen. Verify the sticker iscorrectly applied and check that thedrawbar and the trailer dimensions arewithin the allowed range. If the trailerconsistently does not reverse straight,delete the trailer from the system andrepeat the setup process to calibratethe trailer.
What does it mean if the system remainson one message for an extended timeduring calibration?
The camera could need to be cleaned,the sticker could be blocked, thedrawbar could be outside the allowedrange of 9–18 in (23–46 cm) or youcould need to move to a different areato change the lighting and background.Verify the sticker is in the properlocation. See Applying the TrailerReversing Aid Sticker (page 364). Youcan move to a different area or changethe direction you are driving or set upthe system at a different time of day.Some trailers are not compatible withthe sticker and camera system.
What does it mean if the system pausesduring calibration?
There could be steering input or trailermovement during the straight driveportion of the calibration process.
What does it mean if the system displayshold steering steady during turn?
Part of the calibration process for thesticker setup requires a steady turn. Ifyou are continually moving the steeringwheel during the turn, this delays thecalibration process. To enable thecalibration process, hold the steeringwheel at the same position whenturning.
What does it mean if the system displaysthat it is not available?
There could be a sub-system that thesystem uses that is not correctlyoperating or there could be a batteryvoltage issue. If the system continuesto display it is not available, visit yourauthorized dealer to have your vehiclechecked.
