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.

•Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
•Consult your local motor vehicle laws fortowing a trailer.
•See any instructions that come withtowing accessories for the properinstallation and adjustment specifications.
•Service your vehicle more frequently ifyou tow a trailer. See ScheduledMaintenance (page 552).
•If you use a rental trailer, follow theinstructions the rental agency gives you.
You can find information on loadspecification terms found on the tire labeland Safety Compliance label as well asinstructions on calculating your vehicle's loadin the Load Carrying chapter. See Load Limit(page 293).
Remember to account for the trailer tongueweight as part of your vehicle load whencalculating the total vehicle weight.
Trailer Towing Connector (Vehicleswith a Trailer Towing Package and7–Pin Connector)
When attaching the trailer wiring connectorto your vehicle, only use a proper fittingconnector that works with the vehicle andtrailer functions. Some seven-positionconnectors may have the SAE J2863 logo,which confirms that it is the proper wiringconnector and works correctly with yourvehicle.

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.

If the trailer safety chain hook has a latch,make sure the latch fully closes.
Trailer Brakes (If Equipped)
WARNING: Do not connect a trailer'shydraulic brake system directly to yourvehicle's brake system. Your vehicle maynot have enough braking power and yourchances of having a collision greatlyincrease.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if you installthem properly and adjust them to themanufacturer's specifications. The trailerbrakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.
Separate functioning brake systems arerequired for safe control of towed vehiclesand trailers weighing more than 1500 lb(680 kg) when loaded.
Integrated Trailer Brake Controller (If
Equipped)
WARNING: Use the integrated trailerbrake controller to properly adjust thetrailer brakes and check all connectionsbefore towing a trailer. Failure to followthis instruction could result in the loss ofcontrol of your vehicle, personal injury ordeath.
When used properly, the trailer brakecontroller assists in smooth and effectivetrailer braking by powering the trailer’selectric or electric-over-hydraulic brakes witha proportional output based on the towingvehicle’s brake pressure.
The controller user interface consists of thefollowing:
A: + and - (Gain adjustment buttons): Pressingthese buttons adjusts the controller's poweroutput to the trailer brakes in 0.5 increments.You can increase the gain setting to 10.0(maximum trailer braking) or decrease it to0 (no trailer braking). The gain settingdisplays in the message center.

TowingE265060 E183395

The controller shows gain setting, output bargraph, and trailer connectivity status in theinformation display. They appear in theinformation display as follows:
•Trailer Brake Controller Gain (withouttrailer connected): Shows the current gainsetting during a given ignition cycle andwhen adjusting the gain. This alsodisplays if you use the manual controllever or make gain adjustments with notrailer 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, duringa given ignition cycle. It also displays if atruck or trailer-wiring fault occurs causingthe trailer to appear disconnected. Thismessage can also display if you use themanual control lever without a trailerconnected. After disconnecting the trailerconnector, press the brake pedal forapproximately five seconds to allow thesystem to detect and update the trailerstatus.
B: Manual control lever: Slide the controllever to the left to turn on the trailer's electricbrakes independent of the tow vehicle's. Seethe following Procedure for adjusting gainsection for instructions on proper use of thisfeature. If you use the manual control whilethe brake is also applied, the greater of thetwo inputs determines the power sent to thetrailer brakes.
•Stop lamps: Using the manual controllever illuminates both the trailer brakelamps and your vehicle brake lampsexcept the center high-mount stop lamp,if you make the proper electricalconnection to the trailer. Pressing yourvehicle brake pedal also illuminates bothtrailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note:Only perform this procedure in atraffic-free environment at speeds ofapproximately 20–25 mph (32–40 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 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.

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 as applicationduring trailer sway, could cause instabilityof trailer or tow vehicle.
•Avoid towing in adverse weatherconditions. The trailer brake controllerdoes not provide anti-lock control of thetrailer wheels. Trailer wheels can lock upon slippery surfaces, resulting in reducedstability of trailer and tow vehicle.
•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 the controller.
•The controller interacts with the brakecontrol system and powertrain controlsystem of your vehicle to provide thebest performance on different roadconditions.
•Your vehicle's brake system and thetrailer brake system work independentlyof each other. Changing the gain settingon the controller does not affect theoperation of your vehicle's brakeswhether you attach a trailer or not.
•When you switch the engine off, thecontroller output is disabled and thedisplay and module shut down. Thecontroller module and display turn onwhen you switch the ignition on.
•The trailer brake controller is only afactory-installed or dealer-installed item.Lincoln is not responsible for warranty orperformance of the controller due tomisuse or customer installation.
Trailer Lamps
WARNING: Never connect any trailerlamp wiring to the vehicle's tail lamp wiring;this may damage the electrical systemresulting in fire. Contact your authorizeddealer as soon as possible for assistancein proper trailer tow wiring installation.Additional electrical equipment may berequired.
