Ford F-550 - 2003 Fuse Box Diagram

Never place your arm over the air bag module as a deploying air
bag can result in serious arm fractures or other injuries.
To properly position yourself away from the air bag:
Move your seat to the rear as far as you can while still reaching the
pedals comfortably.
Recline the seat slightly one or two degrees from the upright position.
Do not put anything on or over the air bag module. Placing
objects on or over the air bag inflation area may cause those
objects to be propelled by the air bag into your face and torso causing
serious injury.
Do not attempt to service, repair, or modify the air bag
supplemental restraint systems or its fuses. See your Ford or
Lincoln Mercury dealer.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.
Modifying or adding equipment to the front end of the vehicle
(including frame, bumper, front end body structure and tow
hooks) may affect the performance of the air bag system, increasing
the risk of injury. Do not modify the front end of the vehicle.
Additional equipment such as snowplow equipment may effect
the performance of the air bag sensors increasing the risk of
injury. Please refer to the Body Builders Layout Book for instructions
about the appropriate installation of additional equipment.
Removing the blocker beam without installing snow plow
attachment hardware may effect air bag deployment in a crash.
Do not operate the truck unless either the blocker beam or snow plow
attachment hardware is installed on the vehicle.

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 are
not
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.
AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock feature that prevents
the gearshift lever from being moved from P (Park) when the ignition is
in the ON position unless brake pedal is depressed.
If you cannot move the gearshift lever out of P (Park) with ignition in
the ON position and the brake pedal depressed:
1. Apply the parking brake, turn ignition key to LOCK, then remove the
key.
2. Insert the key and turn it to OFF.
Apply the brake pedal and shift
to N (Neutral)
.
In the ignition OFF position, the automatic transmission shift
lever can be moved from the P (Park) position without the brake
pedal depressed. To avoid unwanted vehicle movement, always set the
parking brake.
3. Start the vehicle.
If it is necessary to use the above procedure to move the gearshift lever,
it is possible that a fuse has blown or the vehicle’s brakelamps are not
operating properly. Refer to
Fuses and relays
in the
Roadside
emergencies
chapter.

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.
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. (For additional information, refer to the
Understanding the positions of the 4–speed automatic
transmission
section in this chapter.
Anticipate stops and brake gradually.
Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
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.
After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park)
(automatic transmission) or N (Neutral) (manual transmissions).
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
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 15 cm (6 inches) above the
bottom edge of the rear bumper.
Disconnect the trailer tow electrical connector to prevent blown fuses
caused by water entering into your trailer’s electrical wiring.

Tires have their maximum inflation pressure and associated load rating
imprinted on the tire sidewall. This pressure may or may not be the
same as that shown as recommended on the vehicle. The vehicle
operator may have to adjust the tire inflation pressure to
accommodate the snowplow and payload. Consult your dealer or
equipment installer for help with proper inflation pressures.
Federal and some local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
After installing a snowplow to the vehicle, ensure the vehicle’s front
toe alignment and front ride height are within specification (reset if
required). These specifications are located in the vehicle’s Workshop
Manual.
Note:
Do not exceed the GVWR or the GAWR specified on the
certification label.
Removing snowplow
After removing a snowplow from the vehicle, ensure the vehicle’s front toe
alignment and front ride height are within specification (reset if required).
Snowplowing with your air bag-equipped vehicle
Your vehicle is equipped with a driver and passenger air bag
Supplemental Restraint System (SRS) The SRS is designed to activate in
certain frontal and offset frontal collisions when the vehicle sustains
sufficient longitudinal deceleration.
Careless or high speed driving while plowing snow which results in
sufficient vehicle decelerations can deploy the air bag. Such driving also
increases the risk of accidents.
All occupants of the vehicle, including the driver, should always
properly wear their safety belts, even when an air bag (SRS) is
provided.
Never remove or defeat the “tripping mechanisms” designed into the
snow removal equipment by its manufacturer. Doing so may cause
damage to the vehicle and the snow removal equipment as well as
possible air bag deployment.
Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln Mercury dealer.

This switch is located in the front
passenger’s footwell, by the kick
panel access cover.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the
switch by pushing in on the reset
button.
4. Turn the ignition ON.
5. Wait a few seconds and return
the key to OFF.
6. Make another check of leaks.
FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:
Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

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 is not recommended and may
compromise the integrity of your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
Spare tire information
Your vehicle may be equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire may be used on the
spare.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Use of such a tire
could result in damage to driveline components and an increased risk
of loss of vehicle control, vehicle rollover, personal injury or death.
If your vehicle is equipped with a tire pressure monitoring
system, refer to Tire Pressure Monitoring System (if equipped)
in the Maintenance and specifications section for important information
before changing your tires. If the tire pressure monitoring system
becomes damaged, it will no longer function.
