Ford E-350 - 2003 Fuse Box Diagram

Ford E-350 - 2003 Fuse Box Diagram

The National Highway Traffic Safety Administration (NHTSA)
recommends a minimum distance of at least 25 cm (10 inches)
between an occupant
s chest and the driver air bag module.
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.
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 may affect 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.

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.
Do not drive your vehicle until you verify that the brakelamps
are working.
Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your dealer or a qualified service technician.
Understanding the gearshift positions of the 4
speed automatic
transmission
P (Park)
This position locks the transmission and prevents the rear wheels from
turning.
To put your vehicle in gear:
Start the engine
Depress the brake pedal
Move the gearshift lever into the desired gear
Driving

On commmercial stripped chassis
vehicles, this switch is located on a
bracket above the brake pedal.
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
The spare tire for your vehicle is stowed under the rear of your vehicle
(except cutaway and stripped chassis models).
To remove the spare tire:
1. Open the rear doors and remove
the thumb screw and anti-theft
bracket. If finger pressure will not
remove the thumb screw, use the
lug wrench to loosen the screw.
2. Remove the access cover from
the rubber strip behind the left
door.

Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within

Note:
Always replace a fuse with one that has the specified amperage
