2004 LINCOLN NAVIGATOR ignition

The following items may prevent the vehicle from starting:
• Large metallic objects
• Electronic devices on the key chain that can be used to purchase
gasoline or similar items
• A second key on the same key ring as the coded key
If any of these items are present, you need to keep these objects from
touching the coded key while starting the engine. These objects and
devices cannot damage the coded key, but can cause a momentary “ no
start ” condition if they are too close to the key during engine start. If a
problem occurs, turn ignition OFF and restart the engine with all other
objects on the key ring held away from the ignition key. Check to make
sure the coded key is an approved Lincoln coded key.
If your keys are lost or stolen you will need to do the following:
• Use your spare key to start the vehicle, or
• Have your vehicle towed to a dealership or a locksmith. The key codes
will need to be erased from your vehicle and new key codes will need
to be re-coded.
Replacing coded keys can be very costly and you may want to store an
extra programmed key away from the vehicle in a safe place to prevent
an unforeseen inconvenience.
The correct coded key must be used for your vehicle. The use of the
wrong type of coded key may lead to a “ no start ” condition.
If an unprogrammed key is used in the ignition it will cause a “ no
start ” condition.
Programming spare keys
A maximum of eight keys can be coded to your vehicle. Only
SecuriLock
keys can be used. To program a coded key yourself, you
will need two previously programmed coded keys (keys that already
operate your vehicle ’ s engine) and the new unprogrammed key(s) readily
accessible for timely implementation of each step in the procedure.
If two previously programmed coded keys are not available, you must
bring your vehicle to your dealership to have the spare coded key(s)
programmed.
Please read and understand the entire procedure before you begin.

1. Insert the first previously
programmed coded key into the
ignition and turn the ignition from 1
(OFF) to 3 (ON) (maintain ignition
in 3 (ON) for at least three seconds,
but no more than ten seconds).
2. Turn ignition from 3 (ON) back to
1 (OFF) in order to remove the first
coded key from the ignition.
3. Within ten seconds of removing
the first coded key, insert the second previously programmed coded
key into the ignition and turn the ignition from 1 (OFF) to 3 (ON)
(maintain ignition in 3 (ON) for at least three seconds but no more than
ten seconds).
4. Turn the ignition from 3 (ON) back to 1 (OFF) in order to remove the
second coded key from the ignition.
5. Within 10 seconds of removing the second coded key, insert the new
unprogrammed key (new key/valet key) into the ignition and turn the
ignition from 1 (OFF) to 3 (ON) (maintain ignition in 3 (ON) for at least
three seconds, but no more than ten seconds). This step will program
your new key to a coded key.
6. To program additional new unprogrammed key(s), repeat this
procedure from step 1.
If successful, the new coded key(s) will start the vehicle ’ s engine and the
theft indicator will illuminate for three seconds and then go out.
If not successful, the new coded key(s) will not start the vehicle ’ s engine
and the theft indicator will flash on and off and you may repeat steps 1
through 5. If failure repeats, bring your vehicle to your dealership to
have the new spare key(s) programmed. 43

The power folding seats are designed to stall within 1 – 10 seconds
of encountering an obstruction when opening or closing. Should
this occur, remove the obstruction and wait approximately 1 – 4
minutes for the seat motor to reset.
The power fold down seats will operate for 30 minutes after the
ignition switch is in Off. The transmission must be in P (park),
and the liftgate, or liftgate glass must be open. Similar to the
Battery Saver feature, the power 3rd row seat will be disabled 30
minutes after turning the vehicle off. If the power 3rd row seat is
disabled after 30 minutes, the seat can be enabled by opening any
door, pressing the unlock key on the key fob, pressing any keyless

SAFETY RESTRAINTS
Personal Safety System
The Personal Safety System provides an improved overall level of frontal
crash protection to front seat occupants and is designed to help further
reduce the risk of air bag-related injuries. The system is able to analyze
different occupant conditions and crash severity before activating the
appropriate safety devices to help better protect a range of occupants in
a variety of frontal crash situations.
Your vehicle ’ s Personal Safety System consists of:
• Driver and passenger dual-stage air bag supplemental restraints.
• Front safety belts with pretensioners, energy management retractors,
and safety belt usage sensors.
• Driver ’ s seat position sensor.
• Front crash severity sensor.
• Restraints Control Module (RCM).

Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System to tailor the air bag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer to Safety Belt section in this chapter.
Front safety belt pretensioners
The front outboard safety belt pretensioners are designed to tighten the
safety belts of the driver and front ouboard passenger firmly against the
occupant ’ s body during a collision. This maximizes the effectiveness of
the safety belts and helps properly position the occupant relative to the
air bag to improve protection. The safety belt pretensioners can be either
activated alone or, if the collision is of sufficient severity, together with
the air bags.
Front safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant ’ s forward momentum. This helps
reduce the risk of force-related injuries to the occupant ’ s chest by
limiting the load on the occupant. Refer to Safety Belt section in this
chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to the Warning Light section in the Instrument Cluster chapter.
Routine maintenance of the Personal Safety System is not required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the air bag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. In addition, the RCM also monitors the restraints
warning light in the instrument cluster. A difficulty with the system is
indicated by one or more of the following:
• The warning light will either flash or stay lit.
• The warning light will not illuminate immediately after the ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.
