FORD 2013 F-550 v.2 - Manual (Page 255)

TRAILER SWAY CONTROL (IF EQUIPPED)
Note: This feature does not prevent trailer sway, but reduces it once it
begins.
Note: This feature cannot stop all trailers from swaying.
Note: In some cases, if vehicle speed is too high, the system may turn
on multiple times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the stability
control light flashes and the message TRAILER SWAY REDUCE SPEED
appears in the information display. The first thing to do is slow your vehicle
down, then pull safely to the side of the road and check for proper tongue
load and trailer load distribution. See the Load Carrying chapter for
specific loading information.
RECOMMENDED TOWING WEIGHTS
Note: Do not exceed a trailer weight of 5000 pounds (2268 kilograms)
when towing with, or by, bumper only.
Note: The total area in square feet (meters) exposed to air resistance of
a moving vehicle and its trailer is the trailer frontal area. Do not exceed
60 feet
2 (5.57 meters 2 ) trailer frontal area.
Note: Exceeding this limitation may significantly reduce the
performance of your towing vehicle. Selecting a trailer with a low
aerodynamic drag and rounded front design helps optimize performance
and fuel economy.
Note: For high altitude operation, reduce the gross combined weight by
2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.
Note: Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to use electric trailer brakes.
