Follow these guidelines for safe towing:
  • Do not tow a trailer until you drive your vehicle at least 1,000 mi (1,600 km).
  • Consult your local motor vehicle laws for towing a trailer.
  • See the instructions included with towing accessories for the proper installation and adjustment specifications.
  • Service your vehicle more frequently if you tow a trailer. See your scheduled maintenance information.  See   Scheduled Maintenance. 
  • If you use a rental trailer, follow the instructions the rental agency gives you.
See Load limits in the Load Carrying chapter for load specification terms found on the tire label and Safety Compliance label and instructions on calculating your vehicle's load.
Remember to account for the trailer tongue weight as part of your vehicle load when calculating the total vehicle weight.
Trailer Towing Connector
Trailer Tow Connector
When attaching the trailer wiring connector to your vehicle, only use a proper fitting connector that works with the vehicle and trailer functions. Some seven-position connectors may have the SAE J2863 logo, which confirms that it is the proper wiring connector and works correctly with your vehicle.

Hitches
Do not use a hitch that either clamps onto the bumper or attaches to the axle. You must distribute the load in your trailer so that 10-15% of the total weight of the trailer is on the tongue.
Weight-distributing Hitches
WARNING   WARNING:  Do not adjust the spring bars so that your vehicle's rear bumper is higher than before attaching the trailer. Doing so will defeat the function of the weight-distributing hitch, which may cause unpredictable handling, and could result in serious personal injury.

When connecting a trailer using a weight-distributing hitch, always use the following procedure:
  1. Park the loaded vehicle, without the trailer, on a level surface.
  1. Measure the height to the top of your vehicle's front wheel opening on the fender. This is H1.
  1. Attach the loaded trailer to your vehicle without the weight-distributing bars connected.
  1. Measure the height to the top of your vehicle's front wheel opening on the fender a second time. This is H2.
  1. Install and adjust the tension in the weight-distributing bars so that the height of your vehicle's front wheel opening on the fender is approximately halfway down from H2, toward H1.
  1. Check that the trailer is level or slightly nose down toward your vehicle. If not, adjust the ball height accordingly and repeat Steps 2-6.
When the trailer is level or slightly nose down toward the vehicle:
  • Lock the bar tension adjuster in place.
  • Check that the trailer tongue securely attaches and locks onto the hitch.
  • Install safety chains, lighting and trailer brake controls as required by law or the trailer manufacturer.
Safety Chains
Note:   Do not attach safety chains to the bumper.
Always connect the safety chains to the frame or hook retainers of your vehicle hitch.
To connect the safety chains, cross the chains under the trailer tongue and allow enough slack for turning tight corners. Do not allow the chains to drag on the ground.
Trailer Brakes
WARNING   WARNING:  Do not connect a trailer's hydraulic brake system directly to your vehicle's brake system. Your vehicle may not have enough braking power and your chances of having a collision greatly increase.

Electric brakes and manual, automatic or surge-type trailer brakes are safe if you install them properly and adjust them to the manufacturer's specifications. The trailer brakes must meet local and federal regulations.
The rating for the tow vehicle's braking system operation is at the gross vehicle weight rating, not the gross combined weight rating.
Separate functioning brake systems are required for safe control of towed vehicles and trailers weighing more than 1500 lb (680 kg) when loaded.
Integrated Trailer Brake Controller (If Equipped)
WARNING   WARNING:  Use the integrated trailer brake controller to properly adjust the trailer brakes and check all connections before towing a trailer. Failure to follow this instruction could result in the loss of control of your vehicle, personal injury or death.

Note:   The Ford trailer brake controller has been verified to be compatible with trailers having electric-actuated drum brakes (one to four axles) and electric-over-hydraulic brakes. It will not activate hydraulic surge-style trailer brakes. It is the responsibility of the customer to ensure that the trailer brakes are adjusted appropriately, functioning normally and all electric connections are properly made.
Trailer Brake Controller
When used properly, the trailer brake controller assists in smooth and effective trailer braking by powering the trailer’s electric or electric-over-hydraulic brakes with a proportional output based on the towing vehicle’s brake pressure.
The controller user interface consists of the following:
A: + and - (Gain adjustment buttons): Pressing these buttons adjusts the controller's power output to the trailer brakes in 0.5 increments. You can increase the gain setting to 10.0 (maximum trailer braking) or decrease it to 0 (no trailer braking). The gain setting displays in the message center.
The controller shows gain setting, output bar graph, and trailer connectivity status in the information display. They appear in the information display as follows:
  • Trailer Brake Controller Gain (without trailer connected): Shows the current gain setting during a given ignition cycle and when adjusting the gain. This also displays if you use the manual control lever or make gain adjustments with no trailer connected.
  • Trailer Brake Controller Gain Output: Displays when you push your vehicle's brake pedal, or upon use of the manual control. Bar indicators illuminate in the information display to indicate the amount of power going to the trailer brakes relative to the brake pedal or manual control input. One bar indicates the least amount of output; six bars indicate maximum output.
  • Trailer Connected: Displays when the system senses a correct trailer wiring connection (a trailer with electric trailer brakes) during a given ignition cycle.
  • Trailer Disconnected: Displays, accompanied by a single audible tone, when the system senses a trailer connection and then a disconnection, either intentional or unintentional, during a given ignition cycle. It also displays if a truck or trailer-wiring fault occurs causing the trailer to appear disconnected. This message also displays if you use the manual control lever without a trailer connected.
B: Manual control lever: Slide the control lever to the left to switch on the trailer's electric brakes independent of the tow vehicle's. See Procedure for Adjusting Gain section for instructions on proper use of this feature. If you use the manual control while the brake is also applied, the greater of the two inputs determines the power sent to the trailer brakes.
  • Stoplamps: Using the manual control lever illuminates both the trailer brake lamps and your vehicle brake lamps except the center high mounted stoplamp, if you make the proper electrical connection to the trailer. Pressing your vehicle brake pedal also illuminates both trailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note:   Only perform this procedure in a traffic-free environment at speeds of approximately 20-25 mph (30-40 km/h).
The gain setting sets the trailer brake controller for the specific towing condition. You should change the setting as towing conditions change. Changes to towing conditions include trailer load, vehicle load, road conditions and weather.
Set the gain to provide the maximum trailer braking assistance while making sure the trailer wheels do not lock when using the brakes. Locked trailer wheels may lead to trailer instability.
  1. Make sure the trailer brakes are in good working condition, functioning normally and properly adjusted. See your trailer dealer if necessary.
  1. Connect the trailer and make the electrical connections according to the trailer manufacturer's instructions.
  1. When you plug in a trailer with electric or electric-over-hydraulic brakes, a message confirming connection appears in the information display.
  1. Use the gain adjustment (+ and -) buttons to increase or decrease the gain setting to the desired starting point. A gain setting of 6.0 is a good starting point for heavier loads.
  1. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20-25 mph (30-40 km/h) and squeeze the manual control lever completely.
  1. If the trailer wheels lock up, indicated by squealing tires, reduce the gain setting. If the trailer wheels turn freely, increase the gain setting. Repeat Steps 5 and 6 until the gain setting is at a point just below trailer wheel lock-up. If towing a heavier trailer, trailer wheel lock-up may not be attainable even with the maximum gain setting of 10.
Explanation of Information Display Warning Messages
Note:   An authorized dealer can diagnose the trailer brake controller to determine exactly which trailer fault has occurred. However, your Ford warranty does not cover this diagnosis if the fault is with the trailer.
A message indicating a trailer brake module fault may display in response to faults sensed by the trailer brake controller, accompanied by a single tone. If this message appears, contact an authorized dealer as soon as possible for diagnosis and repair. The controller may still function, but performance may be degraded.
A message indicating a trailer wiring fault may display when there is a short circuit on the electric brake output wire. If this message displays, accompanied by a single tone, with no trailer connected, the problem is with your vehicle wiring between the trailer brake controller and the 7-pin connector at the bumper. If the message only displays with a trailer connected, the problem is with the trailer wiring. Consult your trailer dealer for assistance. This can be a short to ground (such as a chaffed wire), short to voltage (such as a pulled pin on trailer emergency breakaway battery) or the trailer brakes may be drawing too much current.
Points to Remember
Note:   Do not attempt removal of the trailer brake controller without consulting the Workshop Manual. Damage to the unit may result.
  • Adjust gain setting before using the trailer brake controller for the first time.
  • Adjust gain setting, see Procedure for Adjusting Gain, whenever road, weather and trailer or vehicle loading conditions change from when the gain was initially set.
  • Only use the manual control lever for proper adjustment of the gain during trailer setup. Misuse, such as application during trailer sway, could cause instability of trailer or tow vehicle.
  • Avoid towing in adverse weather conditions. The trailer brake controller does not provide anti-lock control of the trailer wheels. Trailer wheels can lock up on slippery surfaces, resulting in reduced stability of trailer and tow vehicle.
  • The trailer brake controller is equipped with a feature that reduces output at vehicle speeds below 11 mph (18 km/h) so trailer and vehicle braking is not jerky or harsh. This feature is only available when applying the brakes using your vehicle's brake pedal, not the controller.
  • The controller interacts with the brake control system and powertrain control system of your vehicle to provide the best performance on different road conditions.
  • Your vehicle's brake system and the trailer brake system work independently of each other. Changing the gain setting on the controller does not affect the operation of your vehicle's brakes whether you attach a trailer or not.
  • When you switch the engine off, the controller output is disabled and the display and module shut down. The controller module and display turn on when you switch the ignition on.
  • The trailer brake controller is only a factory-installed or dealer-installed item. Ford is not responsible for warranty or performance of the controller due to misuse or customer installation.
Trailer Lamps
WARNING   WARNING:  Never connect any trailer lamp wiring to the vehicle's tail lamp wiring; this may damage the electrical system resulting in fire. Contact your authorized dealer as soon as possible for assistance in proper trailer tow wiring installation. Additional electrical equipment may be required.

Trailer lamps are required on most towed vehicles. Make sure all running lights, brake lights, direction indicators and hazard lights are working.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of your vehicle-trailer combination before starting on a trip. When turning, make wider turns so the trailer wheels 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 connections and trailer wheel lug nuts thoroughly after you have traveled 50 mi (80 km).
  • When stopped in congested or heavy traffic during hot weather, place the gearshift in park (P) to aid engine and transmission cooling and to help A/C performance.
  • Switch off the speed control with heavy loads or in hilly terrain. The speed control may turn off automatically when you are towing on long, steep grades.
  • Shift to a lower gear when driving down a long or steep hill. Do not apply the brakes continuously, as they may overheat and become less effective.
  • If your transmission is equipped with a Grade Assist or Tow/Haul feature, use this feature when towing. This provides engine braking and helps eliminate excessive transmission shifting for optimum fuel economy and transmission cooling.
  • If your vehicle is equipped with AdvanceTrac with roll stability control, this system may turn on during typical cornering maneuvers with a heavily loaded trailer. This is normal. Turning the corner at a slower speed while towing may reduce this tendency.
  • Allow more distance for stopping with a trailer attached. Anticipate stops and brake gradually.
  • Avoid parking on a grade. However, if you must park on a grade:
  1. Turn the steering wheel to point your vehicle tires away from traffic flow.
  1. Set your vehicle parking brake.
  1. Place the automatic transmission in park (P).
  1. Place wheel chocks in front and back of the trailer wheels. (Chocks not included with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare tire. A temporary spare tire is different in size (diameter or width), tread-type (All-Season or All Terrain) or is from a different manufacturer than the road tires on your vehicle. Consult information on the tire label or Safety Compliance label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note:   Disconnect the wiring to the trailer before backing the trailer into the water.
Note:   Reconnect the wiring to the trailer after removing the trailer from the water.
When backing down a ramp during boat launching or retrieval:
  • Do not allow the static water level to rise above the bottom edge of the rear bumper.
  • Do not allow waves to break higher than 6 in (15 cm) above the bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
  • Causing internal damage to the components.
  • Affecting driveability, emissions and reliability.
Replace the rear axle lubricant anytime the rear axle has been submerged in water. Water may have contaminated the rear axle lubricant, which is not normally checked or changed unless a leak is suspected or other axle repair is required.
