FORD 2015 F-550 v.1 - Manual (Page 207)

• When stopped in congested or
heavy traffic during hot
weather, place the gearshift in
position P to aid engine and
transmission cooling and to
help A/C performance.
• Turn off the speed control with
heavy loads or in hilly terrain.
The speed control may turn off
automatically when you are
towing on long, steep grades.
• 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 a Grade Assist or
Tow/Haul feature, use this
feature 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, this
system may turn on during
typical cornering maneuvers
with a heavily loaded trailer.
This is normal. Turning the
corner at a slower speed while
towing may reduce this
tendency.
• If you are towing a trailer
frequently in hot weather, hilly
conditions, at the gross
combined weight rating (or any
combination of these factors),
consider refilling your rear axle
with synthetic gear lubricant (if
the axle is not already filled
with it). See Capacities and
Specifications (page 301).
• 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:
1. Turn the steering wheel to
point your vehicle tires away
from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic
transmission in position P.
4. Place wheel chocks in front
and back of the trailer wheels.
(Chocks not included with
vehicle.)
Your vehicle may be equipped
with a temporary or conventional
spare tire. A "temporary" spare tire
is different in size (diameter or
width), tread-type (All-Season or
All Terrain) or is from a different
manufacturer than the road tires
on your vehicle. Consult
information on the tire label or
Safety Compliance label for
limitations when using.
