FORD 2015 F-550 v.1 - Manual (Page 206)

• 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
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, 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).
