Ford F-150 2010 Owner's Manual page 267

• When the vehicle is turned off, the TBC Output is disabled and the
display is shut down. Turning the ignition from off to on will awaken
the TBC module.
• The TBC is only a factory or dealer installed item. Ford is not
responsible for warranty or performance of the TBC due to misuse or
customer installation.
• Do not attempt removal of the TBC without consulting the
Workshop Manual. Damage to the unit may result.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking-up trailer lamps.
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 mm) shank diameter. The bumper has a
5,000 lb (2,270 kg) trailer weight and 500 lb (227 kg) tongue weight
capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
When towing a trailer:
• To ensure proper break-in of powertrain components, do not trailer
tow during the first 1,000 miles (1,600 km) of a new vehicle.
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing and don't make full-throttle starts.
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consider turning overdrive off (4–speed transmissions) or using the
tow/haul feature (6–speed transmissions) to help eliminate excessive
shifting and aid in transmission cooling. Refer to Automatic
transmission operation in the Driving chapter.
• Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
