Ford Focus - 2003 Fuse Box Diagram

Do not attempt to service, repair, or modify the air bag
supplemental restraint systems or its fuses. See your Ford or
Lincoln Mercury dealer.
Children and air bags
Children must always be properly
restrained. Accident statistics
suggest that children are safer when
properly restrained in the rear
seating positions than in the front
seating position. Failure to follow
these instructions may increase the
risk of injury in a collision.
Air bags can kill or injure a
child in a child seat.
NEVER
place a rear-facing child
seat in front of an active air bag. If
you must use a forward-facing
child seat in the front seat, move
the seat all the way back.
How does the air bag supplemental restraint system work?
The air bag SRS is designed to
activate when the vehicle sustains
longitudinal deceleration sufficient
to cause the sensors to close an
electrical circuit that initiates air
bag inflation. The fact that the air
bags did not inflate in a collision
does not mean that something is
wrong with the system. Rather, it
means the forces were not of the
type sufficient to cause activation.
Front air bags are designed to
inflate in frontal and near-frontal collisions, not rollover, side-impact, or
rear-impacts unless the collision causes sufficient longitudinal
deceleration.
Seating and Safety Restraints
91
Do not lean your head on the door. The side air bag could injure
you as it deploys from the side of the seatback.
Do not attempt to service, repair, or modify the air bag SRS, its
fuses or the seat cover on a seat containing an air bag. See your
Ford or Lincoln Mercury dealer.
All occupants of the vehicle should always wear their safety belts
even when an air bag SRS is provided.
How does the side air bag system work?
The side air bag system consists of
the following:
An inflatable nylon bag (air bag)
with a gas generator concealed
behind the outboard bolster of
the driver and front passenger
seatbacks.
A special seat cover designed to
allow air bag deployment.
The same warning light,
electronic control and diagnostic
unit as used for the front air
bags.
Two crash sensors located under
the outboard side of the front
seats, attached to the floor.
Side air bags, in combination with seat belts, can help reduce the risk of
severe injuries in the event of a significant side impact collision.
The side air bags are fitted on the outboard side of the seatbacks of the
front seats. In certain lateral collisions, the air bag on the side affected
by the collision will be inflated, even if the respective seat is not
occupied. The air bag was designed to inflate between the door panel
and occupant to further enhance the protection provided occupants in
side impact collisions.
The air bag SRS is designed to activate when the vehicle sustains lateral
deceleration sufficient to cause the sensors to close an electrical circuit
that initiates air bag inflation.
Seating and Safety Restraints

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.
When the key is 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.
2. Remove the protective cover to
the interlock access hole on the
console. Insert a screwdriver or
similar tool to release the interlock.
3. Apply the parking brake, then shift to N (Neutral).
4. 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.

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.

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.
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
Battery
section of the
Maintenance and specifications
chapter.
