Preparing to Tow
*
[DR36550( ALL)01/95]
For your safety and for the good of your
vehicle, use the right equipment for the type of
trailer you tow. Also, make sure that all towing
equipment is properly attached to your vehicle.
If you are not certain that you are using the
right equipment in the proper manner, see your
Ford or Lincoln-Mercury dealer.
*
[DR36600( ALL)01/93]
Hitches
*
[DR36800(B F )12/91]
Do not install a single or multi-clamp type
bumper hitch, or a hitch which attaches to the
axle. Underbody mounted hitches are acceptable
if installed properly. Follow towing instructions
of a reputable rental agency.
*
[DR37000( ALL)12/92]
Whenever a trailer hitch and hardware are
removed, make sure all mounting holes in the
underbody are properly sealed to prevent
noxious gases or water from entering.
*
[DR37300( F )03/91]

The optional step bumpers have a built-in hitch
and only requires a ball with a one inch shank
diameter. This step bumper has a Class III
capability (5000 lb/2,270 kg trailer weight and
500 lb/680 kg tongue weight).
*
[DR37520( F )06/92]

[DR37550(B F )03/91]
NOTE: The rated capacities (as shown in this
guide) for trailer towing with the
factory bumper are only valid when
the trailer hitch ball is installed
directly into the ball hole in the
bumper. Addition of bracketry to either
lower the hitch ball position or extend
the hitch ball rearward will
significantly increase the loads on the
bumper and its attachments. This can
result in the failure of the bumper or
the bumper attachments. Use of any
type of hitch extensions should be
considered abuse.
*
[DR37575(B F )03/91]
If it is necessary to relocate the trailer hitch ball
position a frame mounted trailer hitch must be
installed.
*
[DR37800(ALL )11/89]
Safety Chains
*
[DR37900( ALL)12/92]
Always use safety chains between your vehicle
and trailer. Cross chains under the trailer tongue
and allow slack for turning corners. Connect
safety chains to the vehicle frame or hook
retainers. Never attach chains to the bumper.
*
[DR38000(ALL )01/93]
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.

244 [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.
*
[DR38450( ALL)05/95]
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.

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.
*
[DR38925( ALL)01/95]
Servicing your vehicle if you tow
*
[DR38950( ALL)08/93]
If you tow a trailer for a long distance, your
vehicle will need to be serviced more frequently
than usual. Refer to theMaintenance Schedule and
Recordbooklet for additional information.

[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]
Vehicles with trailers should not be parked on a
grade. However, if you must park on a grade,
place wheel chocks under the trailer's wheels as
follows:
*
[DR40000( ALL)11/89]
q
Apply the foot service brakes and hold.
*
[DR40100( ALL)11/89]
q
Have another person place the wheel chocks
under the trailer wheels.
*
[DR40200( ALL)11/89]
q
With the chocks in place, release the foot
service brakes, making sure the chocks are
holding.
