PRINCIPLE OF OPERATION
WARNINGS
To help avoid personal injury, pleaseread and understand the limitationsof the system as contained in thissection. Sensing is only an aid for some(generally large and fixed) objects whenmoving on a flat surface at parking speeds.Certain objects with surfaces that absorbultrasonic waves, surrounding vehicle'sparking aid systems, traffic controlsystems, fluorescent lamps, inclementweather, air brakes, and external motorsand fans may also affect the function ofthe sensing system; this may includereduced performance or a false activation.
To help avoid personal injury, alwaysuse caution when in reverse (R) andwhen using the sensing system.
This system is not designed toprevent contact with small or movingobjects. The system is designed toprovide a warning to assist the driver indetecting large stationary objects to avoiddamaging your vehicle. The system maynot detect smaller objects, particularlythose close to the ground.
Certain add-on devices such as largetrailer hitches, bike or surfboard racksand any device that may block thenormal detection zone of the system, maycreate false beeps.
Note:Keep the sensors, located on thebumper or fascia, free from snow, ice andlarge accumulations of dirt. If the sensorsare covered, the system’s accuracy can beaffected. Do not clean the sensors withsharp objects.
Note:If your vehicle sustains damage tothe bumper or fascia, leaving it misalignedor bent, the sensing zone may be alteredcausing inaccurate measurement ofobstacles or false alarms.
Note:The sensing system cannot be turnedoff when a MyKey is present. See Principleof Operation (page 46).
Note:If you attach certain add-on devicessuch as a trailer or bike rack, the rear sensingsystem may detect that add-on device andtherefore provide warnings. It is suggestedthat you disable the rear sensing systemwhen you attach an add-on device to yourvehicle to prevent these warnings.
The sensing system warns the driver ofobstacles within a certain range of yourvehicle. The system turns on automaticallywhenever you switch the ignition on.
The system can be switched off throughthe information display menu or from thepop-up message that appears once youshift the transmission into reverse (R). SeeGeneral Information (page 92).
Note:On vehicles with front parking aid youcan use the parking aid switch to switch thesystem off.
If a fault is present in the system, a warningmessage appears in the informationdisplay. See Information Messages(page 103).
REAR PARKING AID
The rear sensors are only active when thetransmission is in reverse (R). As yourvehicle moves closer to the obstacle, therate of the audible warning increases.When the obstacle is less than 10 in(25 cm) away, the warning soundscontinuously. If the system detects astationary or receding object farther than10 in (25 cm) from the corners of thebumper, the tone sounds for only threeseconds. Once the system detects anobject approaching, the warning soundsagain.

The Blind Spot Information Systemilluminates an amber alert indicator in theoutside mirror on the side of your vehiclethe approaching vehicle is coming from.When the Blind Spot Information Systemis alerting on a vehicle and thecorresponding turn signal is ON, the BlindSpot Information System alert indicatorflashes as an increased warning level.
The alert indicator dims when the systemdetects nighttime darkness.
Note:The alert indicator flashes in case ofan alert and the turn signal is set to that sideat the same time.
System Sensor Blockage
WARNING
To help avoid injuries, NEVER use theBlind Spot Information System as areplacement for using the interiorand exterior mirrors or looking over yourshoulder before changing lanes. The BlindSpot Information System is not areplacement for careful driving.
The system uses radar sensors that arelocated behind the bumper fascia on eachside of your vehicle. Any dirt, mud andsnow in front of the sensors and/or drivingin heavy rain can cause systemdegradation. Also, other types ofobstructions in front of the sensor cancause system degradation. This is referredto as a ‘blocked’ condition.
Note:Do not apply bumper stickers and/orrepair compound to these areas, this cancause degraded system performance.

If the system detects a degradedperformance condition, a message warningof a blocked sensor will appear in theinformation display. Also the BLIS alertindicators will remain ON and BLIS will nolonger provide any vehicle warnings. Youcan clear the information display warningbut the alert indicators will remainilluminated.
A "blocked" condition can be cleared intwo ways:
•After the blockage in front of thesensors is removed or therainfall/snowfall rate decreases orstops, drive for a few minutes in trafficto allow the sensors to detect passingvehicles.
•By cycling the ignition from ON to OFFand then back ON.
Note:If your vehicle has a tow bar with afactory equipped trailer tow module and itis towing a trailer, the sensors willautomatically turn the Blind SpotInformation System off. If your vehicle hasa tow bar but no factory equipped trailertow module, it is recommended to turn theBlind Spot Information System offmanually. Operating the Blind SpotInformation System with a trailer attachedwill cause poor system performance.
System Errors
If the system senses a problem with theleft or right sensor, the telltale willilluminate and a message will appear inthe information display. See InformationMessages (page 103).
Switching the System Off and On
You can temporarily switch the Blind SpotInformation System off in the informationdisplay. See General Information (page92). When the Blind Spot InformationSystem switches off, you will not receivealerts and the information display showsa system off message. The telltale in thecluster also illuminates. When you switchthe Blind Spot Information System on oroff, the alert indicators flash twice.
Note:The Blind Spot Information Systemremembers the last selected on or offsetting.
You can also have the Blind SpotInformation System switched offpermanently at an authorized dealer. Onceswitched off permanently, the system canonly be switched back on at an authorizeddealer.
CROSS TRAFFIC ALERT
WARNING
To help avoid personal injury, NEVERuse the Cross Traffic Alert system asa replacement for using the interiorand exterior mirrors and looking over yourshoulder before backing out of a parkingspace. Cross Traffic Alert is not areplacement for careful driving.
Cross Traffic Alert is designed to warn youof vehicles approaching from the sideswhen the transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you startthe engine and you shift into reverse (R).Once shifted out of reverse (R), CrossTraffic Alert turns off.
Note:Cross Traffic Alert only functionswhile your transmission is in reverse (R).

Zone coverage also decreases whenparking at shallow angles. Here, the leftsensor is mostly obstructed; zone coverageon that side is severely limited.
System Lights, Messages andAudible Alerts
The Cross Traffic Alert illuminates anamber alert indicator in the outside mirroron the side of your vehicle the approachingvehicle is coming from. Cross Traffic Alertalso sounds an audible alert and amessage appears in the informationdisplay indicating a vehicle is coming fromthe right or left. Cross Traffic Alert workswith the reverse sensing system thatsounds its own series of tones. See RearParking Aid (page 181).
The system uses radar sensors that arelocated behind the bumper fascia on eachside of your vehicle. Do not allow mud,snow or bumper stickers to obstruct theseareas, this can cause degraded systemperformance. See Blind SpotInformation System (page 188). If theBlind Spot Information System is blocked,Cross Traffic Alert is also blocked. Acorresponding message appears in theinformation display as soon as you shiftthe transmission into reverse (R).
System Limitations
Cross Traffic Alert has its limitations;situations such as severe weatherconditions or debris build-up on the sensorarea may limit vehicle detection.

ROOF RACKS AND LOAD
CARRIERS
WARNING
When loading the roof racks, werecommend you evenly distribute theload, as well as maintain a lowcenter of gravity. Loaded vehicles, withhigher centers of gravity, may handledifferently than unloaded vehicles. Takeextra precautions, such as slower speedsand increased stopping distance, whendriving a heavily loaded vehicle.
The maximum recommended load, evenlydistributed on the crossbars, is 200 lb(90 kg).
Note:Never place loads directly on the roofpanel. The roof panel is not designed todirectly carry a load.
For correct roof rack system function, youmust place loads directly on crossbarsaffixed to the roof rack side rails. Whenusing the roof rack system, we recommendyou use Ford Genuine Accessory crossbarsdesigned specifically for your vehicle.
Make sure that you securely fasten theload. Check the tightness of the loadbefore driving and at each fuel stop.
Adjusting the Crossbar
1.Loosen the thumbwheels at both endsof the crossbar by turning themcounterclockwise (both crossbars areadjustable).
2. Slide the crossbar to the desiredlocation.
3.Tighten the thumbwheels at both endsof the crossbar by turning themclockwise.
Make sure to check that the thumbwheelsare tight each time you add or remove loadfrom the roof rack, and periodically whiletraveling. Make sure that the load is securebefore traveling.

To calculate the maximum loaded trailerweight for your vehicle:
1. Start with the gross combined weightrating for your vehicle model and axleratio. See the following chart.
2.Subtract all of the following that applyto your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such as adraw bar, ball, locks or weightdistributing
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggage weight
•Aftermarket equipment weight.
3. This equals the maximum loadedtrailer weight for this combination.
Note:The trailer tongue load figures intothe payload for your vehicle. Reduce thetotal payload by the final trailer tongueweight.
Consult an authorized dealer to determinethe maximum trailer weight allowed foryour vehicle if you are not sure.

Weight-distributing Hitch - Vehicleswithout Automatic LevelingSuspension
WARNING
Do not adjust a weight-distributinghitch to any position where the rearbumper of the vehicle is higher thanit was before attaching the trailer. Doingso will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1. Park the loaded vehicle, without thetrailer, on a level surface.
2. Measure the height to the top of yourvehicle's front wheel opening on thefender. This is H1.
3.Attach the loaded trailer to your vehiclewithout the weight-distributing barsconnected.
4. Measure the height to the top of yourvehicle's front wheel opening on thefender a second time. This is H2.
5. Install and adjust the tension in theweight-distributing bars so that theheight of your vehicle's front wheelopening on the fender is approximatelyhalf the way down from H2, toward H1.
6.Check that the trailer is level or slightlynose down toward your vehicle. If not,adjust the ball height accordingly andrepeat Steps 2-6.
When the trailer is level or slightly nosedown toward the vehicle:
•Lock the bar tension adjuster in place.
•Check that the trailer tongue securelyattaches and locks onto the hitch.
•Install safety chains, lighting, and trailerbrake controls as required by law or thetrailer manufacturer.

Weight-distributing Hitch - Vehicleswith Automatic Leveling Suspension
WARNING
Do not adjust a weight-distributinghitch to any position where the rearbumper of the vehicle is higher thanit was before attaching the trailer. Doingso will defeat the function of theweight-distributing hitch, which may causeunpredictable handling, and could resultin serious personal injury.
Note:If you do not move the loaded vehiclefor approximately 12 hours, the levelingsystem may bleed down to a lower height.This can be especially apparent if you leavea trailer attached to the parked vehicle forlong periods. You must drive your vehicle inorder to re-level the suspension.
When hooking-up a trailer using aweight-distributing hitch, always use thefollowing procedure:
1. Load the interior of the vehicle to aweight similar to that which you intendto carry when towing. This includesthings such as passenger weight andcargo.
2. Drive the vehicle for approximately 2miles (3 kilometers) to re-level thesuspension.
3. Park the loaded vehicle, without thetrailer, on a level surface.
4. Measure the height to the top of yourvehicle's front wheel opening on thefender. This is H1.
5.Attach the loaded trailer to your vehiclewithout the weight-distributing barsconnected.
6.Make sure you securely attach and lockthe trailer tongue to the hitch.
7.Install safety chains, lighting, and trailerbrake controls as required by law or thetrailer manufacturer.
8. Drive the vehicle and trailer at 20–25mph (32–40 km/h) for approximately2 miles (3 kilometers) to re-level thesuspension.
9. Park your vehicle and trailer on a levelsurface.
10.Measure the height to the top of yourvehicle's front wheel opening on thefender a second time. This is H2.
11. Install and adjust the tension in theweight-distributing bars so that theheight of your vehicle's front wheelopening on the fender isapproximately half the way downfrom H2, toward H1.
12. Check that the trailer is level orslightly nose down toward yourvehicle. If not, remove the trailer,adjust the ball height accordingly andrepeat Steps 5-11.
When the trailer is level or slightly nosedown toward the vehicle:
•Lock the bar tension adjuster in place.
•Check that the trailer tongue securelyattaches and locks onto the hitch.
•Install safety chains, lighting, and trailerbrake controls as required by law or thetrailer manufacturer.
Safety Chains
Note:Do not attach safety chains to thebumper.

The controller shows gain setting, outputbar graph, and trailer connectivity statusin the information display. They appear inthe information display as follows:
•Trailer Brake Controller Gain (withouttrailer connected): Shows the currentgain setting during a given ignition cycleand when adjusting the gain. This alsodisplays if you use the manual controllever or make gain adjustments withno trailer connected.
•Trailer Brake Controller Gain Output:Displays when you push your vehicle'sbrake pedal, or upon use of the manualcontrol. Bar indicators illuminate in theinformation display to indicate theamount of power going to the trailerbrakes relative to the brake pedal ormanual control input. One bar indicatesthe least amount of output; six barsindicate maximum output.
•Trailer Connected: Displays when thesystem senses a correct trailer wiringconnection (a trailer with electric trailerbrakes) during a given ignition cycle.
•Trailer Disconnected: Displays,accompanied by a single audible time,when the system senses a trailerconnection and then a disconnection,either intentional or unintentional,during a given ignition cycle. It alsodisplays if a truck or trailer-wiring faultoccurs causing the trailer to appeardisconnected. This message can alsodisplay if you use the manual controllever without a trailer connected. Afterdisconnecting the trailer connector,press the brake pedal forapproximately five seconds to allowthe system to detect and update thetrailer status.
B: Manual control lever: Slide the controllever to the left to turn on the trailer'selectric brakes independent of the towvehicle's. See the following Procedure foradjusting gain section for instructions onproper use of this feature. If you use themanual control while the brake is alsoapplied, the greater of the two inputsdetermines the power sent to the trailerbrakes.
•Stop lamps: Using the manual controllever illuminates both the trailer brakelamps and your vehicle brake lampsexcept the center high-mount stoplamp, if you make the proper electricalconnection to the trailer. Pressing yourvehicle brake pedal also illuminatesboth trailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note:Only perform this procedure in atraffic-free environment at speeds ofapproximately 20-25 mph (30-40 km/h).
The gain setting sets the trailer brakecontroller for the specific towing condition.You should change the setting as towingconditions change. Changes to towingconditions include trailer load, vehicle load,road conditions and weather.
The gain should be set to provide themaximum trailer braking assistance whilemaking sure the trailer wheels do not lockwhen using the brakes. Locked trailerwheels may lead to trailer instability.
1.Make sure the trailer brakes are in goodworking condition, functioning normallyand properly adjusted. See your trailerdealer if necessary.
2. Hook up the trailer and make theelectrical connections according to thetrailer manufacturer's instructions.
3. When you plug in a trailer with electricor electric-over-hydraulic brakes, amessage confirming connectionappears in the information display.

4. Use the gain adjustment (+ and -)buttons to increase or decrease thegain setting to the desired startingpoint. A gain setting of 6.0 is a goodstarting point for heavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20-25 mph (30-40 km/h) andsqueeze the manual control levercompletely.
6. If the trailer wheels lock up, indicatedby squealing tires, reduce the gainsetting. If the trailer wheels turn freely,increase the gain setting. Repeat Steps5 and 6 until the gain setting is at apoint just below trailer wheel lock-up.If towing a heavier trailer, trailer wheellock-up may not be attainable evenwith the maximum gain setting of 10.
Explanation of Information DisplayWarning Messages
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred.However, your Ford warranty does not coverthis diagnosis if the fault is with the trailer.
A message indicating a trailer brakemodule fault may display in response tofaults sensed by the trailer brake controller,accompanied by a single tone. If thismessage appears, contact an authorizeddealer as soon as possible for diagnosisand repair. The controller may stillfunction, but performance may bedegraded.
A message indicating a trailer wiring faultmay display when there is a short circuiton the electric brake output wire. If thismessage displays, accompanied by asingle tone, with no trailer connected, theproblem is with your vehicle wiringbetween the trailer brake controller andthe 7-pin connector at the bumper. If themessage only displays with a trailerconnected, the problem is with the trailer
wiring. Consult your trailer dealer forassistance. This can be a short to ground(such as a chaffed wire), short to voltage(such as a pulled pin on trailer emergencybreakaway battery) or the trailer brakesmay be drawing too much current.
Points to Remember
Note:Do not attempt removal of the trailerbrake controller without consulting theWorkshop Manual. Damage to the unit mayresult.
•Adjust gain setting before using thetrailer brake controller for the first time.
•Adjust gain setting, using the procedureabove, whenever road, weather andtrailer or vehicle loading conditionschange from when the gain was initiallyset.
•Only use the manual control lever forproper adjustment of the gain duringtrailer setup. Misuse, such asapplication during trailer sway, couldcause instability of trailer or towvehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control ofthe trailer wheels. Trailer wheels canlock up on slippery surfaces, resultingin reduced stability of trailer and towvehicle.
•The trailer brake controller is equippedwith a feature that reduces output atvehicle speeds below 11 mph (18 km/h)so trailer and vehicle braking is not jerkyor harsh. This feature is only availablewhen applying the brakes using yourvehicle's brake pedal, not thecontroller.
•The controller interacts with the brakecontrol system and powertrain controlsystem of your vehicle to provide thebest performance on different roadconditions.
