If your vehicle goes off the edge of the pavement
•If your vehicle goes off the edge of the pavement, slow down, but
avoid severe brake application, ease the vehicle back onto the
pavement only after reducing your speed. Do not turn the steering
wheel too sharply while returning to the road surface.
•It may be safer to stay on the apron or shoulder of the road and slow
down gradually before returning to the pavement. You may lose
control if you do not slow down or if you turn the steering wheel too
sharply or abruptly.
•It often may be less risky to strike small objects, such as highway
reflectors, with minor damage to your vehicle rather than attempt a
sudden return to the pavement which could cause the vehicle to slide
sideways out of control or roll over. Remember, your safety and the
safety of others should be your primary concern.
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.
Vehicle used as a stationary power source
Auxiliary equipment called power take-off, or PTO, is often added to the
engine or transmission to operate utility equipment. Examples include
wheel-lift for tow trucks, tools for construction, and cranes. PTO
applications draw auxiliary horsepower from the powertrain, often while
the vehicle is stationary. In this condition there is limited cooling air flow
through the radiator and around the vehicle that normally occurs when a
vehicle is moving. Depending on the level and duration of auxiliary
horsepower draw, vehicle and surrounding environmental conditions, and
other factors, this can contribute to elevated transmission fluid
temperatures and resultant accelerated fluid deterioration, fuel vapor
over-pressurization, and other concerns. Ford trucks are fully qualified
for stationary PTO operation for 10 minutes or less of continuous
operation. For stationary PTO operation of extended duration (beyond
10 minutes), diesel engine is recommended. Further consult your

aftermarket PTO installer since the duration of operation limit for the
aftermarket PTO may be less than 10 minutes.
A more complete description of PTO operation is discussed in the Ford
Truck Body Builders Layout Book, found at

DRIVING THROUGH WATER
If driving through deep or standing water is unavoidable, proceed very
slowly especially when the depth is not known. Never drive through
water that is higher than the bottom of the hubs (for trucks) or the
bottom of the wheel rims (for cars). When driving through water,
traction or brake capability may be limited. Also, water may enter your
engine’s air intake and severely damage your engine or your vehicle may
stall.Driving through deep water where the transmission vent
tube is submerged may allow water into the transmission and
cause internal transmission damage.
Once through the water, always dry the brakes by moving your
vehicle slowly while applying light pressure on the brake pedal.
Wet brakes do not stop the vehicle as quickly as dry brakes.

Note:With extended use, the flasher may run down your battery.
FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine
when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch
may have been activated.
Except for commercial stripped
chassis vehicles, this switch is
located in the front passenger’s
footwell, by the kick panel.

Power distribution box
The power distribution box is located in the engine compartment. The
power distribution box contains high-current fuses that protect your
vehicle’s main electrical systems from overloads.
Always disconnect the battery before servicing high current
fuses.
To reduce risk of electrical shock, always replace the cover to
the Power Distribution Box before reconnecting the battery or
refilling fluid reservoirs.
If the battery has been disconnected and reconnected, refer to the
Batterysection of theMaintenance and Specificationschapter.

Engine compartment relay module
The engine compartment relay module is located in one of two places
depending on which type of engine your vehicle is equipped with:
•Gasoline engine: driver side of the engine compartment above the
brake master cylinder.
•Diesel engine: passenger side of the engine compartment behind the
power distribution box.
Have a certified technician or your dealer service this module, if
required.
The relays are coded as follows:

CHANGING A FLAT TIRE
If you get a flat tire while driving:
•do not brake heavily.
•gradually decrease the vehicle’s speed.
•hold the steering wheel firmly.
•slowly move to a safe place on the side of the road.
The use of tire sealants may damage your tires.

Tire change procedure
Preparing to change the tire
To help 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).
4. Apply the parking brake and turn
the 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.

6. Remove the spare tire and jack from the storage location.
•the jack is located in the rear
right-hand side of the cargo area.
7. Use the tapered end of the lug nut wrench to unscrew wheel
ornaments attached by retaining screws. Remove any wheel trim. Insert
the tapered end of the lug nut wrench behind wheel covers or hubcaps
and twist off.
8. Loosen the wheel nut by pulling up on the handle of the lug nut
wrench about one-half turn (counterclockwise). Do not remove the
wheel lug nuts until you raise the tire off the ground.
Replacing the tire
1. Assemble the jack handle sections together and lock into the jack. Use
the jack handle to slide the jack under the vehicle.
To lessen the risk of personal injury, do not put any part of your
body under the vehicle while changing a tire. Do not start the
engine when your vehicle is on the jack. The jack is only meant for
changing the tire.
