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 309).
Your vehicle may have electrical items,such as fuses or relays, related totowing. See Fuses (page 341).
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 292).
You can also find information in the RV& Trailer Towing Guide available at yourauthorized dealer, or online.

Note:These are hitch ratings only. Actualvehicle ratings are dependent on engine,transmission and axle combinations.
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.
