TOWING A TRAILER
WARNING: Towing trailersbeyond the maximum recommendedgross trailer weight exceeds the limitof your vehicle and could result inengine damage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
Note: See Recommended TowingWeights (page 310).
Your vehicle may have electrical items,such as fuses or relays, related totowing. See Fuses (page 342).
Your vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Inspectthese components periodically during,and after, any towing operation.
Load Placement
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.
•Select a ball mount with the correctrise or drop and load capacity. Whenboth the loaded vehicle and trailerare connected, the trailer frameshould be level, or slightly angleddown toward your vehicle, whenviewed from the side.
When driving with a trailer or payload, aslight takeoff vibration or shudder maybe present due to the increased payloadweight. Additional information regardingproper trailer loading and setting yourvehicle up for towing is located inanother chapter of this manual. SeeLoad Limit (page 293).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.

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.

Towing

1.Grab the trailer hitch cover at the bottomand pull towards the rear of the vehicleuntil the bottom of the trailer hitch coverunsnaps from the bumper.
2. Grab the trailer hitch cover at the edgeand rotate until the top of the trailer hitchcover unsnaps from the bumper, thenremove the trailer hitch cover.
To install the trailer hitch cover:
1. Line up the snaps on the trailer hitchcover to the holes on the bumper andpush forward until it snaps into place.
Hitches
WARNING: Do not cut, drill, weld ormodify the trailer hitch. Modifying the trailerhitch could reduce the hitch rating.
Do not use a hitch that either clamps ontothe bumper or attaches to the axle.
Distribute the trailer load so 10-15% of thetotal trailer weight is on the tongue.
Integrated Hitch Rating
WARNING: Towing trailers beyondthe maximum recommended gross trailerweight exceeds the limit of your vehicleand could result in engine damage,transmission damage, structural damage,loss of vehicle control, vehicle rollover andpersonal injury.
The standard integrated hitch has two ratingsdepending on mode of operation:
•Weight-carrying mode requires a drawbar and hitch ball. The draw bar supportsall the vertical tongue load of the trailer.
•Weight-distributing mode requires anaftermarket weight-distributing system,which includes draw bar, hitch ball, springbars and snap-up brackets. This systemdistributes the vertical tongue load of thetrailer between the truck and the trailer.

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.

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.
Trailer lamps are required on most towedvehicles. Make sure all running lights, brakelights, turn signals and hazard lights areworking.

Towing

Before Towing a Trailer
Practice turning, stopping and backing up toget the feel of your vehicle-trailercombination before starting on a trip. Whenturning, make wider turns so the trailerwheels clear curbs and other obstacles.
When Towing a Trailer
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control when carryingheavy loads or in hilly terrain. The speedcontrol may turn off automatically whenyou are towing on long, steep grades.
•Shift to a lower gear when driving downa long or steep hill. Do not apply thebrakes continuously, as they mayoverheat and become less effective.
•If your transmission has a Grade Assistor Tow/Haul feature, use this featurewhen towing. This provides enginebraking and helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•If your vehicle has AdvanceTrac withRSC, this system may turn on duringtypical cornering maneuvers with aheavily loaded trailer. This is normal.Turning the corner at a slower speedwhile towing may reduce this tendency.
•If your vehicle has Adaptive suspension,you can select NORMAL or SPORT drivecontrol modes for better experiencewhen towing a trailer. See InformationDisplays (page 119).
•If you are towing a trailer frequently inhot weather, hilly conditions, at the grosscombined weight rating (or anycombination of these factors), considerrefilling your rear axle with synthetic gearlubricant (if the axle is not already filledwith it). See Capacities andSpecifications (page 422).
•Allow more distance for stopping with atrailer attached. Anticipate stops andbrake gradually.
•Avoid parking on a grade. However, ifyou must park on a grade:
1. Turn the steering wheel to point yourvehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the transmission in park (P).
4.Place wheel chocks in the front and backof the trailer wheels.
Note:Chocks are not included with yourvehicle.
