Towing

When Towing a Trailer • Do not tow during the first 1,000 mi (1,600 km). • Do not make full-throttle starts. • Check your hitch, electrical connections and trailer wheel lug nuts thoroughly after you have traveled 50mi (80 km). • When stopped in congested or heavy traffic during hot weather, place the transmission in park (P) to aid engine and transmission cooling and to help A/C performance. • Turn 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 slopes. • 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 featurewhen 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 RSC, this system may turn on during typical cornering maneuverswith a heavily loaded trailer. This is normal. Turning the corner at a slower speedwhen towingmay reduce this tendency. • If you are towing a trailer frequently in hot weather, hilly conditions, at the gross combined weight rating (or any combinationof these factors), consider refilling your rear axle with synthetic gear lubricant if the axle is not already filled with it. See Capacities and Specifications (page 370).

• 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 Never connect any trailer lampwiring 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 andhazard 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.
