2004 LINCOLN AVIATOR Electrical

4. Disconnect the electrical
connector by pulling downward.
5. Rotate the high beam bulb
counterclockwise until the tabs on
the bulb line up with the ring, and
the bulb can be removed by pulling
rearward.
To install the new bulb:
Handle a halogen headlamp bulb carefully and keep out of
children's reach. Grasp the bulb only by its plastic base and do
not touch the glass. The oil from your hand could cause the bulb to
break the next time the headlamps are operated.
1. Push the bulb straight in,
carefully aligning the plastic tabs in
the base of the bulb with the
openings in the plastic ring.
2. Rotate the bulb clockwise until it
stops.
3. Reconnect the electrical
connector to the bulb.
4. Install the headlamp on the
vehicle by aligning the four plastic projections into the four holes,
pushing rearward to seat the lamp assembly.
5. Insert the two retainers, making sure that the retainers go over both
plastic projections on each side of the lamp, pushing the retainers down
until they seat.
6. Replace the plastic radiator cover by inserting the edge of the cover
into the tongue and groove of the mating cover, and then rotating the
cover downward. Press firmly on the cover over each headlamp and in
the center of the cover to re-engage the snap in fasteners.
7. Turn the headlamps on and make sure they work properly. If the
headlamp was correctly aligned before you changed the bulb, you should
not need to align it again.
If a low beam headlamp bulb fails, take your vehicle to your
dealer or a qualified service technician to have it replaced.

AUXILIARY POWER POINT (IF EQUIPPED)
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.
The auxiliary power point is located
inside the center console.
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 can supply a maximum of 240 Watts, a
15A fuse can supply a maximum of 180 Watts and a 10A fuse can 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.

high voltage lines.
For optimum calibration, turn off all electrical accessories (heater/air
conditioning, wipers, etc.) and make sure all vehicle doors are shut.
1. Turn ignition to the ON position.
2. Start the engine.
3. Determine your magnetic zone by
referring to the zone map.
4. From Info menu, select the
Compass/Odometer function. (Do
not select Trip, DTE, or AFE. The
top of the message center must be
blank).
5. Press and hold the RESET and
SETUP control until the message
center display changes to show the
current zone setting.
6. Release the RESET AND SETUP
control, then slowly press RESET
down again.
7. Press the SETUP control
repeatedly until the correct zone
setting for your geographic location is displayed on the message center.
To exit the zone setting mode press and release the RESET control.

CHECK CHARGING SYSTEM.Displayed when the electrical system is
not maintaining proper voltage. If you are operating electrical accessories
when the engine is idling at a low speed, turn off as many of the
electrical loads as soon as possible. If the warning stays on or comes on
when the engine is operating at normal speeds, have the electrical
system checked as soon as possible.
LOW BRAKE FLUID LEVEL.Indicates the brake fluid level is low and
the brake system should be inspected immediately. Refer toChecking
and adding brake fluidin theMaintenance and specifications
chapter.
LOW OIL PRESSURE.Displayed when the engine oil pressure is low. If
this warning message is displayed, check the level of the engine oil.
Refer toEngine oilin theMaintenance and specificationschapter for
information about adding engine oil.
TRANSMISSION OVERHEATED.Indicates the transmission is
overheating. This warning may appear when towing heavy loads, city
driving, when driving in a low gear at a high speed for an extended
period of time or due to a loss of transmission fluid. Stop the vehicle as
soon as safely possible, place the shift lever into P (Park) or N (Neutral)
and raise the engine RPM. If this does not cool the transmission, turn off
the engine and let it cool. If the warning stays on or continues to come
on, contact your dealer for transmission service as soon as possible.
Continued operation in this condition may cause internal transmission
damage.
CHECK TRANSMISSION.Indicates the transmission is not operating
properly. If this warning stays on, contact your dealer as soon as possible
to prevent additional transmission damage. Refer to the instrument
cluster warning lamps in theInstrument clusterchapter.
LOW WASHER FLUID LEVEL.Indicates the washer fluid reservoir is
less than one quarter full. Check the washer fluid level. Refer to
Windshield washer fluidin theMaintenance and specifications
chapter.
CHECK ADVTRAC (if equipped).Displayed when the AdvanceTracy
system is not operating properly. If this message is displayed on the
message center the AdvanceTracysystem will be partially operable. If
this warning stays on while the engine is running, contact your dealer as
soon as possible. For further information, refer toAdvanceTracy
stability enhancement systemin theDrivingchapter.

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.
NEVERplace 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. The driver and passenger airbags 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

The air bags inflate and deflate
rapidly upon activation. After air bag
deployment, it is normal to notice a
smoke-like, powdery residue or
smell the burnt propellant. This may
consist of cornstarch, talcum
powder (to lubricate the bag) or
sodium compounds (e.g., baking
soda) that result from the
combustion process that inflates the
air bag. Small amounts of sodium
hydroxide may be present which
may irritate the skin and eyes, but
none of the residue is toxic.
While the system is designed to help
reduce serious injuries, contact with a deploying air bag may also cause
abrasions, swelling or temporary hearing loss. Because air bags must
inflate rapidly and with considerable force, there is the risk of death or
serious injuries such as fractures, facial and eye injuries or internal
injuries, particularly to occupants who are not properly restrained or are
otherwise out of position at the time of air bag deployment. Thus, it is
extremely important that occupants be properly restrained as far away
from the air bag module as possible while maintaining vehicle control.
Several air bag system components get hot after inflation. Do not
touch them after inflation.
If the air bag has deployed,the air bag will not function again
and must be replaced immediately.If the air bag is not
replaced, the unrepaired area will increase the risk of injury in a collision.
The SRS consists of:
²driver and passenger air bag modules (which include the inflators and
air bags),
²one or more impact and safing sensors and diagnostic monitor (RCM),
²a readiness light and tone
²the electrical wiring which connects the components.
The RCM (restraints control module) monitors its own internal circuits
and the supplemental air bag electrical system wiring (including the
impact sensors, the system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors).
