Ford Town Car - 2003 Fuse Box Diagram

Ford Town Car - 2003 Fuse Box Diagram

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.
The front passenger air bag is not designed to offer protection to
an occupant in the center front seating position.
Modifications 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 sensors increasing the risk of injury. Do not
modify the front end of the vehicle.
Seating and Safety Restraints
125
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side air bags and
increase the risk of injury in an accident.
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
supplemental restraint system, 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 including the driver should always
wear their safety belts even when an air bag SRS is provided.
How does the side air bag system work?
The design and development of the
side airbag system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags.
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 airbag 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.

2. Insert the key and turn it to OFF.
Apply the brake pedal and shift
to N (Neutral)
.
In the OFF position, the automatic transmission shift lever can
be moved from the P (Park) position without the brake pedal
depressed. To avoid unwanted 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.
If your vehicle gets stuck in mud or snow it may be rocked out by
shifting from forward and reverse gears, stopping between shifts, in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a few minutes or damage
to the transmission and tires may occur or the engine may
overheat.
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.
Driving with a 4–speed automatic transmission
Understanding gearshift positions
To put your vehicle in gear, start the engine, depress the brake pedal,
then move gearshift lever out of P (Park).

The fuel pump shut-off switch is located on a bracket inside of the
luggage compartment.
Use the following procedure to reset the fuel pump shut-off switch.
1. Turn the ignition to the OFF position.
2. Check the fuel system for leaks.
3. If no fuel leak is apparent, reset the fuel pump shut-off switch by
pushing in on the reset button.
4. Turn the ignition to the ON position. Pause for a few seconds and
return the key to the OFF position.
5. Make a further check for leaks in the fuel system.
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 THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and 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).
Roadside Emergencies

CLOCK
Press the right control to move the
time display foward.
Press the left control to move the
time display backwards.
AUXILIARY POWER POINT
Power outlets are designed for
accessory plugs only. Do not
hang any type of accessory or
accessory bracket from the plug.
Improper use of the power
outlet can cause damage not
covered by your warranty.
Do not plug optional electrical
accessories into the cigarette lighter.
Use the power point.
Do not use the power point for operating the cigarette lighter element.
The Maximum power each power point can supply depends on the fuse
rating. For example: a 20A fuse should supply a maximum of 240 Watts,
a 15A fuse should supply a maximum of 180 Watts and a 10A fuse should
supply a maximum of 120 Watts. Exceeding these limits will result in a
blown fuse.
Always keep the power point caps closed when not being used.
The auxiliary power point is located under the instrument panel.

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.
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.
Seating and Safety Restraints

A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, have the SRS serviced
at your dealership or by a qualified technician immediately. Unless
serviced, the system may not function properly in the event of a
collision.
Side air bag system (if equipped)
Do not place objects or mount equipment on or near the air bag
cover on the side of the seatbacks of the front seats or in front
seat areas that may come into contact with a deploying air bag. Failure
to follow these instructions may increase the risk of personal injury in
the event of a collision.
Do not use accessory seat covers. The use of accessory seat
covers may prevent the deployment of the side air bags and
increase the risk of injury in an accident.
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.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
