tow FORD EXPEDITION 1998 1.G Owner's Manual

is properly attached to your
vehicle. See your dealer or a
reliable trailer dealer if you require
assistance.
If your vehicle is not equipped
with the factory heavy duty trailer
tow option, auxiliary coolers are
recommended for the automatic
transmission system if you are
planning on:
²traveling farther than 80 km
(50 miles)
²towing in hilly terrain
²towing frequently
Hitches
Do not use hitches that clamp onto
the vehicle's bumper or attach to
the axle. You must distribute the
load in your trailer so that 10 to
15% of the total weight of the
trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a
load equalizing hitch, always use
the following procedure:
1. Park the unloaded vehicle on a
level surface. With the ignition on
and all doors closed, allow the
vehicle to stand for several
minutes so that it can level.
2. Turn the air suspension (if
equipped) control to OFF.
3. Measure the height of a
reference point on the front and
rear bumpers at the center of the
vehicle.
Driving
121

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.
Trailer lamps
Trailer lamps are required on most
towed vehicles. Make sure your
trailer lamps conform to local and
Federal regulations. See your
dealer or trailer rental agency for
proper instructions and equipment
for hooking up trailer lamps.
Using a step bumper
The rear bumper is equipped with
an integral hitch and requires only
a ball with a 25.4 mm (one inch)
shank diameter. The bumper has a
1 814 kg (4 000 lb.) trailer weight
and 181 kg (400 lb.) tongue weight
capability.
Use a frame-mounted weight
distributing hitch for trailers over
1814 kg (4 000 lb).
Driving while you tow
Do not drive faster than 88 km/h
(55 mph) when towing a trailer.
Speed control may shut off if you
are towing on long, steep grades.
When towing a trailer:
²Use D (Drive) or a lower gear
when towing up or down steep
hills. This will eliminate
excessive downshifting and
Driving
123

upshifting for optimum fuel
economy and transmission
cooling.
²Anticipate stops and brake
gradually.
Servicing after towing
If you tow a trailer for long
distances, your vehicle will require
more frequent service intervals.
Refer to the Severe Duty Schedule
in your ªService Guideº for more
information.
Towing behind another vehicle
Do not tow your vehicle behind
another vehicle, such as an RV.
Your vehicle cannot be flat towed
with all wheels on the ground.
Trailer towing tips
²Practice turning, stopping and
backing up in an area before
starting on a trip to get the feel
of the vehicle trailer
combination. When turning,
make wider turns so the trailer
wheels will clear curbs and
other obstacles.
²Allow more distance for
stopping with a trailer attached.
²The trailer tongue weight should
be 10±15% of the loaded trailer
weight.
²After you have traveled 80 km
(50 miles), thoroughly check
your hitch, electrical
connections and trailer wheel
lug nuts.
Driving

LUGGAGE RACK
Load luggage at the front crossbar
and adjust the rear crossbar as
necessary.
²Do not exceed 90.7 kg (200 lb)
of luggage if the weight is
placed directly on the crossbars.
²Do not exceed 68 kg (150 lb) if
the weight is resting directly on
the roof.
To adjust the luggage rack, loosen
the adjusting levers by pushing
them toward the front of the
vehicle, then slide the crossbar
forward and lock the adjusting
levers by pulling them toward the
back of the vehicle.
FUEL CONSUMPTION
Fuel economy can be improved by
avoiding:
²lack of regular, scheduled
maintenance
²excessive speed
²rapid acceleration
²extended idle
