FORD 2011 F-150 v.3 - Manual (Page 274)

• The TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lock-up;
therefore, if these systems are not functioning properly, the TBC may
not function at full performance.
• Your vehicle’s brake system and the trailer brake system work
independently of each other; changing the GAIN setting on the TBC
does not affect the operation of your vehicle’s brakes whether a trailer
is attached or not.
• When the vehicle is turned off, the TBC output is disabled and the
display is shut down; turning the ignition from off to on awakens 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:
• 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.
• Activate the tow/haul feature to eliminate excessive transmission
shifting and assist in transmission cooling. For additional information,
refer to Automatic transmission operation in the Driving chapter.
