Lincoln Navigator - 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.
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 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.
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.

3. Pull the bezel assembly up far
enough to expose the inside of the
gearshift lever compartment.
4. Press and hold the white button
located along side the shifter
housing assembly (as shown in the
illustration). Press the gearshift
lever release on the shifter knob and
move the gearshift lever back to N
(Neutral) (two places rearward from
P [Park]).
5. Start the vehicle and release the
parking brake.
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.

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).
Spare tire information
Your vehicle is equipped with a spare tire that may be used as a spare or
a regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:
Item
Location
Spare tire
Under the vehicle, just forward of
the rear bumper
Jack tools and jacking instructions
Under the access panel located in
the floor compartment behind the

AUTOMATIC TRANSMISSION OPERATION
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, 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.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to LOCK, then remove the
key.
2. Using a smooth, non-metallic tool
(such as a plastic screwdriver, or
equivalent) between the shift lever
boot and the plastic bezel, pry the
bezel assembly away from its locking
tabs.
Use caution not to damage
the plastic bezel assembly or
shift lever boot when prying the
bezel assembly from the locking
tabs.
3. Pull the bezel assembly up far
enough to expose the inside of the
gearshift lever compartment.

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 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.
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

Safety Canopy
²
system
Do not place objects or
mount equipment on or
near the headliner at the siderail
that may come into contact with a
deploying Safety Canopy
±
. Failure
to follow these instructions may
increase the risk of personal injury
in the event of a collision.
Do not lean your head on the door. The Safety Canopy
±
could
injure you as it deploys from the headliner.
Do not attempt to service, repair, or modify the Safety Canopy
±
system, its fuses, the A, B, or C pillar trim, or the headliner on a
vehicle containing a Safety Canopy
±
. 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 and Safety
Canopy
±
system is provided.
To reduce risk of injury, do not obstruct or place objects in the
deployment path of the inflatable Safety Canopy
±
.

AUTOMATIC TRANSMISSION OPERATION
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, 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.
If the fuse is not blown, perform the following procedure:
1. Apply the parking brake, turn the ignition to LOCK, then remove the
key.
2. Using a smooth, non-metallic tool
(such as a plastic screwdriver, or
equivalent) between the shift lever
boot and the plastic bezel, pry the
bezel assembly away from its locking
tabs.
Use caution not to damage
the plastic bezel assembly or
shift lever boot when prying the
bezel assembly from the locking
tabs.
3. Pull the bezel assembly up far
enough to expose the inside of the
gearshift lever compartment.
Driving
228
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.
