tow FORD SUPER DUTY 2004 1.G Owner's Guide

Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
this chapter.
Loaded vehicles may handle differently than unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum GCWR chart (in theTrailer Towing
section in this chapter) for your type of engine and rear axle ratio.
2. Weigh your vehicle without cargo. To obtain correct weights, take your
vehicle to a shipping company or an inspection station for trucks.
3. Subtract your loaded weight from the maximum GCWR in the chart.
This is the maximum trailer weight your vehicle can tow. It must be
below the maximum trailer weight shown in the chart.
TRAILER TOWING
Your vehicle may tow a Conventional/Class IV trailer or fifth wheel trailer
provided the maximum trailer weight is less than or equal to the
maximum trailer weight listed for your engine and rear axle ratio on the
following charts.
2nd unit bodies are not included in maximum trailer weight ratings. The
weight of the additional“body”must be subtracted from the maximum
trailer weight.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.

Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully prior to and after any towing operation. The
following trailer towing charts apply to vehicles equipped with gasoline
engines; for Diesel engines, refer to the Diesel supplement.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of vehicle
control, vehicle rollover and personal injury.
Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer other
than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the spare tire label for limitations
when using.
Refer toTransmission temperature gaugein theInstrument cluster
chapter for transmission fluid temperature information.

Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
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%–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. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
3. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within 0–13 mm (0.5 in) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 2.
Note:Adjusting an equalizing hitch so the rear bumper of the vehicle is
higher than it was unloaded will defeat the function of the load
equalizing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer’s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer’s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
