light LINCOLN NAVIGATOR 2004 Repair Manual

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
.
How does the Safety Canopy  system work?
The design and development of the
Safety Canopy
system included
recommended testing procedures
that were developed by a group of
automotive safety experts known as
the Side Air Bag Technical Working
Group. These recommended testing
procedures help reduce the risk of
injuries related to the deployment of
side airbags (including the Safety
Canopy
).
The Safety Canopy
system
consists of the following:
• An inflatable nylon curtain with a
gas generator concealed behind
the headliner and above the doors
(one on each side of vehicle).
• A headliner designed to flex open
above the side doors to allow Safety Canopy
deployment.
• The same warning light, electronic control and diagnostic unit as used
for the front airbags.

Several Safety Canopy

system components get hot
after inflation. Do not touch them
after inflation.
If the Safety Canopy
system has deployed, the Safety
Canopy
will not function again unless replaced. The
Safety Canopy
system (including the A, B and C pillar trim)
must be inspected and serviced by a qualified technician in
accordance with the vehicle service manual. If the Safety
Canopy
is not replaced, the unrepaired area will increase the risk of
injury in a collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer to the Air bag readiness
section in the Instrument Cluster chapter. Routine maintenance of the
air bag is not required.
Any difficulty with the system is indicated by one or more of the
following:
• The readiness light (same light as for front air bag system) will either
flash or stay lit.
• The readiness light will not illuminate immediately after ignition is
turned on.
• A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and 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
or rollover event.
Disposal of air bags and air bag equipped vehicles (including
pretensioners)
See your local dealership or qualified technician. Air bags MUST BE
disposed of by qualified personnel.

STARTING
Positions of the ignition
1. OFF/LOCK, locks the steering
wheel, automatic transmission
gearshift lever and allows key
removal.
2. ACCESSORY, allows the electrical
accessories such as the radio to
operate while the engine is not
running.
3. ON, all electrical circuits
operational. Warning lights
illuminated. Key position when driving.
4. START, cranks the engine. Release the key as soon as the engine
starts.
Preparing to start your vehicle
Engine starting is controlled by the powertrain control system. This
system meets all Canadian Interference-Causing Equipment standard
requirements regulating the impulse electrical field strength of radio
noise.
When starting a fuel-injected engine, avoid pressing the accelerator
before or during starting. Only use the accelerator when you have
difficulty starting the engine. For more information on starting the
vehicle, refer to Starting the engine in this chapter.
Extended idling at high engine speeds can produce very high
temperatures in the engine and exhaust system, creating the risk
of fire or other damage.
Do not park, idle, or drive your vehicle in dry grass or other dry
ground cover. The emission system heats up the engine
compartment and exhaust system, which can start a fire.
Do not start your vehicle in a closed garage or in other enclosed
areas. Exhaust fumes can be toxic. Always open the garage door
before you start the engine. See Guarding against exhaust fumes in
this chapter for more instructions. 43

Make sure the corresponding lights illuminate or illuminate briefly. If a
light fails to illuminate, have the vehicle serviced.
• If the driver ’ s safety belt is fastened, the light may not illuminate.
Starting the engine
Note: Whenever you start your vehicle, release the key as soon as the
engine starts. Excessive cranking could damage the starter.
1. Turn the key to 4 (START)
without pressing the accelerator
pedal and release as soon as the
engine starts. The key will return to
3 (ON).
2. When the engine starts, release
the key.
3. After idling for a few seconds,
apply the brake, shift into gear and
drive.
Note: If the engine does not start within five seconds on the first try,
turn the key to OFF, wait 10 seconds and try again. If the engine still 43

If you smell exhaust fumes inside your vehicle, have your dealer
inspect your vehicle immediately. Do not drive if you smell
exhaust fumes.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 2.5 cm (one inch) or adjust the heating
or air conditioning to bring in fresh air.
BRAKES
Your service brakes are self-adjusting. Refer to the scheduled
maintenance guide for scheduled maintenance.
Occasional brake noise is normal and often does not indicate a
performance concern with the vehicle ’ s brake system. In normal
operation, automotive brake systems may emit occasional or intermittent
squeal or groan noises when the brakes are applied. Such noises are
usually heard during the first few brake applications in the morning;
however, they may be heard at any time while braking and can be
aggravated by environmental conditions such as cold, heat, moisture,
road dust, salt or mud. If a “ metal-to-metal, ”“ continuous grinding ” or
“ continuous squeal ” sound is present while braking, the brake linings
may be worn-out and should be inspected by a qualified service
technician.
If you are driving down a long or steep hill, shift to a lower gear.
Do not apply your brakes continuously, as they may overheat
and become less effective.
Anti-lock brake system (ABS)
On ABS-equipped vehicles, a noise from the hydraulic pump motor and
pulsation in the pedal may be observed during ABS braking events. Pedal
pulsation coupled with noise while braking under panic conditions or on
loose gravel, bumps, wet or snowy roads is normal and indicates proper
functioning of the vehicle ’ s anti-lock brake system. The ABS performs a
self-check after you start the engine and begin to drive away. A brief
mechanical noise may be heard during this test. This is normal. If a
malfunction is found, the ABS warning light will come on. If the vehicle
has continuous vibration or shudder in the steering wheel while braking,
the vehicle should be inspected by a qualified service technician.

The ABS operates by detecting the onset of wheel lockup during brake
applications and compensates for this tendency. The wheels are
prevented from locking even when the brakes are firmly applied.
Using ABS
• In an emergency or when maximum efficiency from the four-wheel
ABS is required, apply continuous force on the brake. The four wheel
ABS will be activated immediately, thus allowing you to retain steering
control of your vehicle and, providing there is sufficient space, will
enable you to avoid obstacles and bring the vehicle to a controlled
stop.
• The anti-lock system does not always reduce stopping distance.
Always leave enough room between your vehicle and the vehicle in
front of you to stop.
• We recommend that you familiarize yourself with this braking
technique. However, avoid taking any unnecessary risks.
ABS warning lamp ABS
The ABS
warning lamp in the instrument cluster momentarily illuminates
when the ignition is turned to the ON position. If the light does not
illuminate momentarily at start up, remains on or continues to flash, the
ABS needs to be serviced.
With the ABS light on, the anti-lock
brake system is disabled and normal
braking is still effective unless the
brake warning light also remains
illuminated with parking brake
released. (If your brake warning lamp illuminates, have your vehicle
serviced immediately.)
Brake Assist (if equipped)
The Brake Assist system provides full braking force during panic braking
situations. It detects a rapid application of the brake pedal and
maximizes the amount of brake booster assist, helping the driver to
achieve maximum braking pressure. Once a panic brake application is
detected, the system will remain activated as long as the brake pedal is
depressed. The system is deactivated by releasing the brake pedal.
When the system activates, the brake pedal will travel with very little
effort; this is normal. P!BRAKE

The Roll Stability Control button
allows the driver to control the
availability of the Roll Stability
Control system. The Roll Stability
Control system status is indicated
by a warning indicator light with a
“ sliding car ” icon in the instrument cluster that will flash when the
system is activated and an indicator light in the control button that will
illuminate when the system is turned off. In vehicles with a message
center, the message “ Roll Stability Control OFF ” will be displayed.
If a failure is detected in the Roll Stability Control system, the warning
indicator light in the instrument cluster will stay on. If the warning
indicator light in the instrument cluster remains on while the engine is
running, have the system serviced immediately.
Pressing the button once will disable the Roll Stability Control stability
enhancement and the engine power reduction portion of the traction
enhancement feature; the brake portion of the traction enhancement
feature will still function normally. Pressing and holding the button for
more than five seconds will disable the Roll Stability Control stability
enhancement and traction enhancement feature. If the vehicle is stuck
in snow or mud or when driving in deep sand, switching off the Roll
Stability Control system may be beneficial so the wheels are allowed to
spin. If your vehicle seems to lose engine power while driving in deep
sand or very deep snow, switching off the Roll Stability Control stability
enhancement feature will restore full engine power and will enhance
momentum through the obstacle.
Some drivers may notice a slight movement of the brake pedal when the
Roll Stability Control performs a system self-check. During Roll Stability
Control operation you may experience the following:
• A rumble or grinding noise
• A slight deceleration of the vehicle
• The Roll Stability Control indicator light will flash
• If your foot is on the brake pedal, you will feel a vibration in the
pedal.
• If the driving condition is severe and your foot is not on the brake, the
brake pedal will move to apply higher brake forces. You may also hear
a whoosh of air from under the instrument panel during this severe
condition.
All these conditions are normal during Roll Stability Control operation. O

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.
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.
Driving with a 4 – speed automatic transmission
Your vehicle ’ s automatic transmission is equipped with a special shift
strategy that insures maximum heater performance during cold weather
operation.
When ambient temperature is – 5 ° C (23 ° F) or below and the engine
coolant temperature is below 38 ° C (100 ° F), light throttle upshifts may
2004 Navigator (nav)
Owners Guide (post-2002-fmt)
USA English (fus) Driving
233

be slightly delayed. Once the engine coolant temperature reaches 71 ° C
(160 ° F) the normal shift strategy will resume. This is normal operation
and will not affect the function or the durability of the transmission.
If the normal shift strategy does not resume once the engine
coolant temperature reaches the normal operating temperature,
or if the downshifts and other throttle conditions do not function
normally, see your dealer or a qualified service technician as soon
as possible.
Understanding gearshift positions
To put your vehicle in gear, start the engine, depress the brake pedal,
then move gearshift lever out of P (Park).
Hold the brake pedal down while you move the gearshift lever
from P (Park) to another position. If you do not hold the brake
pedal down, your vehicle may move unexpectedly and injure someone.
P (Park)
Always come to a complete stop
before shifting into P (Park). Make
sure the gearshift lever is securely
latched in P (Park). This position
locks the transmission and prevents
the rear wheels from turning.
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. P

control switch (TCS) on the end of the gearshift lever with the gearshift
in the position. The TCIL will illuminate in the instrument cluster.
Transmission operates in gears one through three. (Drive) provides
more engine braking than (Overdrive) and is useful when:
• driving with a heavy load.
• towing a trailer up or down steep hills.
• additional engine downhill braking is desired. If towing a trailer, refer
to Driving while you tow in the Trailer towing section.
To return to
(Overdrive) mode, press the transmission control switch
(TCS). The TCIL will no longer be illuminated.
Each time the vehicle is started, the transmission will automatically
return to normal overdrive mode.
