TRAILER SWAY CONTROL
WARNING: Turning off trailer swaycontrol increases the risk of loss of vehiclecontrol, serious injury or death. Ford doesnot recommend disabling this featureexcept in situations where speed reductionmay be detrimental (such as hill climbing),the driver has significant trailer towingexperience, and can control trailer swayand maintain safe operation.
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 multiple times,gradually reducing vehicle speed.

This feature applies your vehicle brakes atindividual wheels and, if necessary, reducesengine power. If the trailer begins to sway,the stability control light flashes and themessage TRAILER SWAY REDUCE SPEEDappears in the information display. The firstthing to do is slow your vehicle down, thenpull safely to the side of the road and checkfor proper tongue load and trailer loaddistribution. See Load Carrying (page 288).
RECOMMENDED TOWING
WEIGHTS
Note:Do not exceed the trailer weightfor your vehicle configuration listed inthe chart below.
Note:Make sure to take intoconsideration trailer frontal area. Do notexceed 36.5 feet² (3.39 meters²) if yourvehicle is equipped with the standardtowing package, or 60 feet² (5.57meters²) if your vehicle is equipped withthe optional heavy duty package.
Note:Exceeding this limitation maysignificantly reduce the performance ofyour towing vehicle. Selecting a trailerwith a low aerodynamic drag androunded front design helps optimizeperformance and fuel economy.
Note:For high altitude operation,reduce the gross combined weight by2% per 1,000 ft (300 m) starting at the1,000 ft (300 m) elevation point.
Note:Certain states require electrictrailer brakes for trailers over a specifiedweight. Be sure to check stateregulations for this specified weight. Themaximum trailer weights listed may belimited to this specified weight, as thevehicle’s electrical system may notinclude the wiring connector needed to
activate electric trailer brakes.
Your vehicle may tow a trailer providedthe maximum trailer weight is less thanor equal to the maximum trailer weightlisted for your vehicle configuration onthe following chart.
To calculate the maximum loaded trailerweight for your vehicle:
1.Start with the gross combined weightrating for your vehicle model andaxle ratio. See the following chart.
2.Subtract all of the following that
apply to your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such as adraw bar, ball, locks or weightdistributing
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggageweight
•Aftermarket equipment weight.
3. This equals the maximum loadedtrailer weight for this combination.
Note:The trailer tongue load figuresinto the payload for your vehicle.Reduce the total payload by the finaltrailer tongue weight.

Weight-distributing Hitch
WARNING: Do not adjust the springbars so that your vehicle's rear bumper ishigher than before attaching the trailer.Doing so 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 the heightof your vehicle's front wheel opening onthe fender is approximately half the waydown 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 nose downtoward 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. Always connect the safety chainsto the frame or hook retainers of your trailerhitch.
Install trailer safety chains to the trailer hitchas recommended by the manufacturer. Crossthe chains under the trailer tongue and allowenough slack for turning tight corners. Donot allow the chains to drag on the ground.

Towing

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 trailer wheelsmay 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 electric orelectric-over-hydraulic brakes, a messageconfirming connection appears in theinformation display.
4.Use the gain adjustment (+ and -) buttonsto increase or decrease the gain settingto the desired starting point. A gainsetting of 6.0 is a good starting point forheavier loads.
5. In a traffic-free environment, tow thetrailer on a dry, level surface at a speedof 20–25 mph (32–40 km/h) andsqueeze the manual control levercompletely.
6.If the trailer wheels lock up, indicated bysquealing tires, reduce the gain setting.If the trailer wheels turn freely, increasethe gain setting. Repeat Steps 5 and 6until the gain setting is at a point justbelow trailer wheel lock-up. If towing aheavier trailer, trailer wheel lock-up maynot be attainable even with the maximumgain setting of 10.
Explanation of Information Display WarningMessages
Note:An authorized dealer can diagnosethe trailer brake controller to determineexactly which trailer fault has occurred.However, your warranty does not cover thisdiagnosis if the fault is with the trailer.
A message indicating a trailer brake modulefault may display in response to faults sensedby the trailer brake controller, accompaniedby a single tone. If this message appears,contact an authorized dealer as soon aspossible for diagnosis and repair. Thecontroller may still function, but performancemay be degraded.
A message indicating a trailer wiring faultmay display when there is a short circuit onthe electric brake output wire. If this messagedisplays, accompanied by a single tone, withno trailer connected, the problem is with yourvehicle wiring between the trailer brakecontroller and the 7-pin connector at thebumper. If the message only displays with atrailer connected, the problem is with thetrailer 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 brakes maybe drawing too much current.
