Maximum trailer weight for all cutaway (E-350 and E-450) vehicles
must be calculated by subtracting the weight of the vehicle (including
incomplete vehicle weight and payload which includes second unit
body weight, cargo and passengers) from the GCW. Otherwise,
maximum trailer weight is 10,000 lb. (4536 kg).
For high altitude operation reduce GCWR by 2% per 1,000 ft. (300
meters) elevation.
To determine the maximum trailer weight designed for your particular
vehicle as equipped, follow the sectionCalculating the load your
vehicle can tow/carryearlier in this chapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Distribute the load so that only 10–15% of the total is on the tongue. Tie
down the load so that it does not shift and change the weight on the hitch.

Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.
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.
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 or install hitches that clamp onto the bumper or to the axle.
Underbody hitches are acceptable if installed properly.
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.
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.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.

Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.
Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a one inch (25.4 mm) shank diameter. The bumper has a 5,000
lb. (2,270 kg) trailer weight and 500 lb. (227 kg) tongue weight capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
When towing a trailer:
•Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
•Do not exceed 50 mph (80 km/h) for the first 500 miles (800 km) of
towing and do not perform fast accelerations from a stop during this
time.
•Consult your local motor vehicle speed regulations for towing a trailer.
•To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling.
•Anticipate stops and brake gradually.
When descending long, steep downhill grades, always use a lower gear to
provide engine braking to save wear on brakes. Use Drive (Overdrive
OFF) on moderately steep hills, Second (2) on steep hills, and First (1)
on very steep hills.Do not apply your brakes continuously, as they
may overheat and become less effective.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourscheduled maintenance
informationfor more information.
Trailer towing tips
•Practice turning, stopping and backing up 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.

•Allow more distance for stopping with a trailer attached.
•The trailer tongue weight should be 10–15% of the loaded trailer
weight.
•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCW, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube. Refer to the
Maintenance and specificationschapter for the lubricant
specification.
•Do not tow a trailer for the first 500 miles (800 km) after changing
the rear axle lube
•Do not exceed 50 mph (80 km/h) for the first 500 miles (800 km) of
towing and do not perform and fast accelerations from a stop during
this time.
•After you have traveled 50 miles (80 km), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
•When stopped in traffic for long periods of time in hot weather, place
the gearshift in P (Park) and increase idle speed. This aids engine
cooling and air conditioner efficiency.
•Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer’s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.
•do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.

RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
An example of recreational towing would be towing your vehicle on a
trip behind a motorhome. Follow these guidelines if you have the need
for recreational towing of your vehicle with all four wheels on the
ground. These guidelines are designed to ensure that your transmission
is not damaged.
2WD vehicles (with automatic transmissions):
•Place the transmission in N (Neutral)
•Maximum speed is 35 mph (56 km/h)
•Maximum distance is 50 miles (80 km)
If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must
be exceeded, the drive shaft will have to be removed.
Ford recommends the driveshaft be removed/installed only by a qualified
technician. See your local dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.

A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.
TRACTION-LOK AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle. The axle may
exhibit a slight noise or vibration in tight turns with low vehicle speed.
This is normal behavior and indicates the axle is working.
PREPARING TO DRIVE YOUR VEHICLE
Utility vehicles have a significantly higher rollover rate than
other types of vehicles.
In a rollover crash, an unbelted person is significantly more likely
to die than a person wearing a safety belt.
Your vehicle has larger tires and increased ground clearance, giving the
vehicle a higher center of gravity than a passenger car.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
Loaded vehicles, with a higher center of gravity, 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.
VEHICLE STABILITY AND HANDLING
The risk of a rollover crash increases as the number of people and load
in the vehicle increase. This increased risk occurs because the passenger
weight and load raises the vehicle’s center of gravity and causes it to

shift rearward. As a result, the van has less resistance to rollover and
handles differently from other commonly driven passenger vehicles,
making it more difficult to control in an emergency situation. Placing any
load on the roof also raises the center of gravity and increases the
potential for rollover.
The van should be operated by an experienced driver. An organization
that owns a 15–passenger van should select one or two experienced
drivers to drive the van on a regular basis. These drivers will gain
valuable experience handling the van. This experience will help make
each trip safer.
The van should be operated at a safe speed which, in some conditions,
may be less than the posted speed limit.
Further, all occupants should be properly restrained. Most people killed
in rollover crashes were unbelted. Occupants can dramatically reduce
their risk of being killed or seriously injured in a rollover crash by simply
using their seat belts. Organizations that own 15–passenger vans should
have a written seat belt use policy. Drivers should be responsible for
enforcing the policy.
EMERGENCY MANEUVERS
•In an unavoidable emergency situation where a sudden sharp turn
must be made, remember to avoid “over-driving” your vehicle, i.e.,
turn the steering wheel only as rapidly and as far as required to avoid
the emergency. Excessive steering will result in less vehicle control,
not more. Additionally, smooth variations of the accelerator and/or
brake pedal pressure should be utilized if changes in vehicle speed are
called for. Avoid abrupt steering, acceleration or braking which could
result in an increased risk of loss of vehicle control, vehicle rollover
and/or personal injury. Use all available road surface to return the
vehicle to a safe direction of travel.
•In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
Vehicles with a higher center of gravity such as utility and
four-wheel drive vehicles handle differently than vehicles with a
lower center of gravity. Utility and four-wheel drive vehicles arenot
designed for cornering at speeds as high as passenger cars any more
than low-slung sports cars are designed to perform satisfactorily under
off-road conditions. Avoid sharp turns, excessive speed and abrupt
maneuvers in these vehicles. Failure to drive cautiously could result in
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
