Trailer Lamps; Using A Step Bumper; Before Towing A Trailer; When Towing A Trailer - Ford Super Duty Owner's Manual

Trailer Lamps

WARNING: Never connect any trailer lamp wiring to the
vehicle's tail lamp wiring; this may damage the electrical system
resulting in a fire. Contact an 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, turn signals and hazard lights are working.
Using a Step Bumper (If Equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a one-inch (25.4 millimeter) shank diameter. The bumper has a
5000-pound (2268 kilogram) trailer weight and a 500-pound (227 kilogram)
tongue weight capacity.
If it is necessary to relocate the hitch ball position, you must install a
frame-mounted trailer hitch.

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 miles
(800 kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections and trailer wheel lug nuts
thoroughly after you have traveled 50 miles (80 kilometers).
• When stopped in congested or heavy traffic during hot weather, place
the gearshift in position 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 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.
