Trailer Lamps; Driving While You Tow - Ford Econoline/Club Wagon E-150 Owner's Manual

Trailer lamps

Make sure your trailer lamps conform to Federal
and local regulations.
Class I and Class II Trailer Tow electrical wiring
provides two circuits (right hand and left hand)
to operate trailer stop/turn tail lamps. Each
stop/turn circuit will operate one combination
stop/turn light bulb (#1157, 3157, 2357, or 3357)
on the trailer. Never add more than one trailer
light bulb to one circuit.
Always replace a fuse with one that has
the specified amperage rating. Using a
fuse with a higher amperage rating can
cause severe wire damage and could start
a fire.

Driving While You Tow

Be especially careful when driving while you
tow a trailer. Never drive faster than 45 mph
(70 km/h) when you tow in hilly country on
hot days. Also, anticipate stops so that you can
brake gradually.
If you use the speed control while you are
towing on very long, steep grades, the speed
control may shut off.
If your vehicle is equipped with an Electronic
4-Speed Automatic (E4OD or 4R70W)
transmission, operate in Overdrive. Refer to the
automatic transmission operation earlier in this
chapter.
When descending a steep grade with a trailer,
operate in Drive rather than Overdrive. If
additional braking is needed, shift the automatic
transmission gearshift into 2 (Second) gear or 1
(Low).
