Trailer Brakes
*
[DR38100( ALL)03/95]
Separate trailer brakes are required on most
towed vehicles weighing over 1,500 lb (680 kg).
*
[DR38200( ALL)05/95]
RWARNING
Do not connect a trailer's hydraulic brake
system directly to your vehicle's brake
system. Your vehicle may not have
enough braking power and your chances
of having a collision greatly increase.
*
[DR38300( ALL)01/93]
Trailer Lamps
*
[DR38400( ALL)11/89]
Make sure your trailer lamps conform to Federal
and local regulations.
[DR38417(B F )05/95]
Your vehicle has been equipped for use with a
4-wire trailer tow electrical system (running
lamps, right hand stop/turn, left hand
stop/turn, and ground).
*
[DR38425(BEF )03/91]
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.
[DR38429(B F )05/95]
A wire harness (Ford part number
F5TB-13A576-A) has been provided that connects
to the frame wire harness at the rear of the
vehicle and is compatible with most 4-wire
trailer tow electrical systems.
[DR38431(B F )05/95]
Always check trailer and vehicle functions (i.e.,
stop/turn signal, and running lights) before
operating your vehicle and trailer.
[DR38433(B F )05/95]
If your vehicle fails to function properly, do not
operate your vehicle and trailer until corrections
are made.

RWARNING
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.
*
[DR38500( ALL)01/95]
Driving while you tow
*
[DR38520( ALL)05/95]
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.
%*
[DR38540( ALL)01/95]
If you use the speed control while you are
towing on very long, steep grades, the speed
control may shut off.
*
[DR38700( ALL)03/94]
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.
*
[DR38800( ALL)10/94]
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).
[DR38810(B F )05/95]
If your vehicle is equipped with a manual
5-speed transmission, operate in 4th gear.
Overdrive (5th) gear should not be used when
towing.
[DR38811(B F )05/95]
If additional braking is needed when descending
a steep grade with a trailer, downshift the
transmission into 3rd gear.

[DR39000( ALL)01/93]
Trailer towing tips
*
[DR39100( ALL)11/89]
Before starting on a trip, practice turning,
stopping and backing in an area away from
heavy traffic. Get to know the ªfeelº of the
vehicle/trailer combination.
*
[DR39200( ALL)05/90]
Practice backing up. Back up very slowly, with
someone outside at the rear of your trailer to
guide you. Place your hand at the bottom of the
steering wheel and move it in the direction you
want the rear of the trailer to swing. Slight
movement of the steering wheel results in a
much larger movement of the rear of the trailer.
*
[DR39300( ALL)11/89]
Allow more room for stopping with a trailer
attached. Trailer brakes should be applied first,
whether manually or automatically controlled,
when approaching a stop.
*
[DR39400( ALL)11/89]
For a good handling truck-trailer combination,
the trailer tongue load should be approximately
10-15% of the loaded trailer weight.
*
[DR39500( ALL)05/95]
Make a thorough check of your equipment
before starting out on the road. After you have
traveled about 50 miles (80 km) stop in a
protected area and double-check your hitch and
electrical connections. Also check trailer wheel
lug nuts for tightness.

[DR39600( ALL)11/89]
When turning, drive slightly beyond the normal
turning point so the trailer wheels will clear
curbs or other obstructions.
*
[DR39725(B F )03/95]
When stopped in traffic for long periods of time
in hot weather, place the gearshift selector lever
in P (Park) to increase the engine idle speed.
This aids in engine cooling and air conditioner
efficiency. If the engine overheats, move the
function selector knob to VENT to stop the
compressor and increase the engine speed for a
short time.
*
[DR39900( ALL)05/90]
