FORD 2013 F-550 v.1 - Manual (Page 260)

• 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.
• If your transmission is equipped with the tow/haul feature, use this
when towing. This provides engine braking and helps eliminate
excessive transmission shifting for optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with AdvanceTrac™ with RSC, you may
experience AdvanceTrac™ with RSC activations during typical
cornering maneuvers with a heavily loaded trailer; this is normal.
Cornering at a slower speed while towing reduces the tendency of the
AdvanceTrac™ stability enhancement system to activate.
• If you are towing a trailer frequently in hot weather, hilly conditions,
at GCWR (or any combination of these factors), consider refilling your
rear axle with synthetic gear lubricant, if not already so equipped. See
the Capacities and Specifications chapter for the lubricant
specification.
• Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
• Avoid parking on a grade. However, if you must park on a grade, place
wheel chocks under the trailer’s wheels.
Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer other
than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the Tire Label or Safety Compliance
Certification Label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer before backing the trailer into
the water.
Note: Reconnect the wiring to the trailer after the trailer is removed
from the water.
When backing down a ramp during boat launching or retrieval:
• Do not allow the static water level to rise above the bottom edge of
the rear bumper.
• Do not allow waves to break higher than 6 inches (15 centimeters)
above the bottom edge of the rear bumper.
