* 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 4 536 kg (10 000 lbs).
For high altitude operation reduce GCWR by 2% per 300 meters (1 000
ft) 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 to 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.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Towing trailers beyond the maximum recommended gross trailer
weight could result in engine damage, transmission/axle damage,
structural damage, loss of control, and personal injury.

²When 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.
²Vehicles 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
When backing down a ramp during boat launching or retrieval,
²Do not allow the static water level to rise above the bottom edge of
the rear bumper and
²Do not allow waves to break higher than 15 cm (6 inches) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter critical vehicle
components, adversely affecting driveability, emissions, reliability and
causing internal transmission damage.
Replace the rear axle lubricant anytime 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.
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.
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 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)
²Place the transmission in N (Neutral)
²Maximum speed is 56 km (35 mph)
²Maximum distance is 80 km (50 miles)
If a distance of 80 km (50 miles) or a speed of 56 km (35 mph) 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.

Tire change procedure
Preparing to change the tire
To prevent the vehicle from moving when you change a tire, be
sure the parking brake is set, then block (in both directions) the
wheel that is diagonally opposite (other side and end of the vehicle) to
the tire being changed.
1. Park on a level surface.
2. Activate the warning flashers.
3. Place the gearshift in P (Park)(automatic transmission).
4. Apply the parking brake and turn
engine OFF.
5. Block the wheel that is diagonally
opposite the tire you are changing.
On E-450 vehicles, the parking
brake is on the transmission.
Therefore, the vehicle will not be
prevented from moving when a rear
wheel is lifted, even if the parking
brake is applied. Be sure to block both directions of the wheel that is
diagonally opposite to the wheel that is being lifted.
If the vehicle slips off the jack, you or someone else could be
seriously injured.

²8-lug wheel
Never use wheels or lug
nuts different than the
original equipment as this could
damage the wheel or mounting
system. This damage could allow
the wheels to come off while the
vehicle is being driven.
9. Replace any wheel covers,
ornaments or hub caps. Make sure they are screwed or snapped in place.
10. Stow the jack, handle and lug wrench.
11. Unblock the wheels.
On vehicles equipped with dual rear wheels, retighten the wheel lug nuts
to the specified torque at 160 km (100 miles), and again at 800 km (500
miles) of new vehicle operation.
On vehicles equipped with single rear wheels, retighten the lug nuts to
the specified torque at 800 km (500 miles) of operation after any wheel
change or any time the lug nuts are loosened.

rust. Do not use oil or grease on threads. Use only Ford recommended
replacement fasteners.

Check the fluid level when it is at ambient temperature, 20É ± 80É F (-7É
± 25É C):
1. Check the fluid level on the dipstick. It should be between the arrows
in the FULL COLD range. Do not add fluid if the level is within this
range.
2. If the fluid level is low, start the engine.
3. While the engine idles, turn the steering wheel left and right several
times.
4. Turn the engine off.
For E-SuperDuty vehicles with the Hydro-Boost Brake System,
do not press the brake pedal after the engine has been turned
off.
5. Recheck the fluid level on the dipstick. Do not add fluid if the level is
between the arrows in the FULL COLD range.
6. If the fluid is low, add fluid in small amounts, continuously checking
the level until it reaches the FULL COLD range. Be sure to put the
dipstick back in the reservoir.
TRANSMISSION FLUID
Checking automatic transmission fluid (if equipped)
Refer to your scheduled maintenance guide for scheduled intervals for
fluid checks and changes. Your transmission does not consume fluid.
However, the fluid level should be checked if the transmission is not
working properly, i.e., if the transmission slips or shifts slowly or if you
notice some sign of fluid leakage.
Automatic transmission fluid expands when warmed. To obtain an
accurate fluid check, drive the vehicle until it is at normal operating
temperature (approximately 30 km [20 miles]). If your vehicle has been
operated for an extended period at high speeds, in city traffic during hot
weather or pulling a trailer, the vehicle should be turned off for about 30
minutes to allow fluid to cool before checking.
1. Drive the vehicle 30 km (20 miles) or until it reaches normal operating
temperature.
2. Park the vehicle on a level surface and engage the parking brake.
