LINCOLN NAVIGATOR 2004 Owners Manual

Each day before you drive, check
your tires. If one looks lower than
the others, use a tire gauge to check
pressure of all tires, and adjust if
required. Check tire pressure with a
tire gauge every few weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor a vehicle which is
overloaded.
Periodically inspect the tire treads and remove stones, nails, glass or
other objects that may be wedged in the tread grooves. Check for holes
or cuts that may permit air leakage from the tire and make necessary
repairs.
Inspect the tire side walls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire demounted and inspected
to determine whether it needs to be repaired or replaced.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.
DRIVING THROUGH WATER
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine ’ s air intake and severely damage your engine.

If driving through deep or standing water is unavoidable, proceed very
slowly. Never drive through water that is higher than the bottom of the
hubs (for trucks) or the bottom of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving through deep water where the transmission vent tube is
submerged may allow water into the transmission and cause
internal transmission damage. Have the fluid checked and, if
water is found, replace the fluid.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
• Base Curb Weight: Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include occupants or
aftermarket equipment.
• Payload: Combined maximum allowable weight of cargo, occupants
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
• GVW (Gross Vehicle Weight): Base curb weight plus payload
weight. The GVW is not a limit or a specification.
• GVWR (Gross Vehicle Weight Rating): Maximum permissible total
weight of the base vehicle, occupants, optional equipment and cargo.
The GVWR is specific to each vehicle and is listed on the Safety
Certification Label on the driver ’ s door pillar.
• GAWR (Gross Axle Weight Rating): Carrying capacity for each axle
system. The GAWR is specific to each vehicle and is listed on the
Safety Certification Label on the driver ’ s door pillar.
• GCW (Gross Combined Weight): The combined weight of the
towing vehicle (including occupants and cargo) and the loaded trailer.
• GCWR (Gross Combined Weight Rating): Maximum permissible
combined weight of towing vehicle (including occupants and cargo)
and the loaded trailer
• Maximum Trailer Weight Rating: Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.

• Maximum Trailer Weight: Maximum weight of a trailer the loaded
vehicle (including occupants and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
• Trailer Weight Range: Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle ’ s GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Safety Certification Label, found on the driver ’ s door pillar, lists
several important vehicle weight rating limitations. Before adding any
additional equipment, refer to these limitations. If you are adding weight
to the front of your vehicle, (potentially including weight added to the
cab), the weight added should not exceed the front axle reserve capacity
(FARC). Additional frontal weight may be added to the front axle reserve
capacity provided you limit your payload in other ways (i.e. restrict the
number of occupants or amount of cargo carried).
Always ensure that the weight of occupants, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both gross vehicle weight and front and rear gross
axle weight rating limits. Under no circumstance should these limitations
be exceeded.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle, loss of vehicle control, vehicle
rollover, and/or personal injury.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see the Preparing to drive your vehicle section in
this chapter.

Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling cargo and people may raise the center of gravity of the vehicle.
Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum gross combined weight rating (GCWR)
chart (in the Trailer Towing section) to find the maximum GCWR for
your type engine and rear axle ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.
TRAILER TOWING
Trailer towing puts additional loads
on your vehicle ’ s engine,
transmission, axle, brakes, tires, and
suspension. For your safety and to
maximize vehicle performance, be
sure to use the proper equipment
while towing.

Follow these guidelines to ensure safe towing:
• Stay within your vehicle ’ s load limits.
• Thoroughly prepare your vehicle for towing. Refer to Preparing to
tow in this chapter.
• Use extra caution when driving while trailer towing. Refer to Driving
while you tow in this chapter.
• Service your vehicle more frequently if you tow a trailer. Refer to the
severe duty schedule in the scheduled maintenance guide.
• Do not tow a trailer until your vehicle has been driven at least 800 km
(500 miles).
• Refer to the instructions included with towing accessories for the
proper installation and adjustment specifications.
Trailer towing (standard equipment):
Your vehicle is equipped with a integrated trailer hitch and a Class I
(4-pin) trailer electrical connector. The 4-pin connector supplies power
to tail lamps, stop lamps, and turn lamps. See the trailer towing chart for
the trailer towing weight recommendation.
Trailer towing (optionally equipped trailer tow package):
The optional trailer tow package includes heavy duty trailer tow wiring.
Both a Class I (4-pin) and IV (7-pin) trailer electrical connector are
provided. Under the instrument panel a electrical connector is provided
for a customer supplied aftermarket electronic brake controller. For
installing a customer supplied electronic brake controller, a electrical
jumper harness and trailer tow electrical instructions are included with
the optional trailer tow package.
The kit containing a electrical jumper and trailer tow electrical
instructions may be purchased from any Ford, Lincoln, or Mercury
dealership (Part number 4L1Z-14A348-AA)
Note: Before towing a trailer, make sure the trailer brakes (if equipped)
and lamps are properly connected and functional. Electronic trailer
brakes (if equipped) refer to the instructions provided by the
aftermarket electronic brake controller manufacture for determining
trailer brake functionality.

Towing trailers beyond the maximum recommended gross trailer
weight exceeds the limit of the vehicle and could result in
engine damage, transmission damage, structural damage, loss of
control, vehicle rollover and personal injury.
INTEGRATED HITCH RATING
The standard integrated hitch has two ratings depending on mode of
operation:
• Weight carrying - requires a draw bar and hitch ball. The draw bar
supports all the vertical tongue load of the trailer.
• Weight distributing - requires an aftermarket weight distributing
system which includes draw bar, hitch ball, spring bars and snap-up
brackets. The vertical tongue load of the trailer is distributed between
the truck and the trailer by this system.
Mode Maximum Gross Trailer
Weight - kg (lbs.) Maximum Tongue
Weight - kg (lbs.)
Weight
carrying 2721 (6000) 272 (600)
Weight
distributing 4014 (8850) 401 (885)
These are hitch ratings only; actual vehicle ratings are dependent on
engine, transmission and axle combinations.
Towing trailers beyond the maximum tongue weight exceeds the
limit of the towing system and could result in vehicle structural
damage, loss of vehicle control and personal injury.
Note: If your vehicle is equipped with AdvanceTrac
, you may
experience AdvanceTrac
activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at
slower speeds while towing will reduce the tendency of the
AdvanceTrac
stability enhancement system to activate.

Trailer hitch cover
Your vehicle is equipped with a removable trailer hitch trim cover. To
remove the trim cover:
1. Loosen the two push pins in the
bottom of the cover by turning them
counterclockwise with a flathead
screwdriver or similar object.
2. To reinstall the cover, insert the
three plastic tabs into their slots (as
shown in the illustration) and push
the cover up into the bumper trim.
3. Hold the cover against the bumper trim and reinstall the two screws.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your dealer or a reliable trailer
dealer if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle ’ s bumper or attach to the
axle. You must distribute the load in your trailer so that 10% – 15% of the
total weight of the trailer is on the tongue.
Load equalizing hitch
When hooking up a trailer using a load equalizing hitch, always use the
following procedure:
1. Park the unloaded vehicle on a level surface. With the ignition in the
ON position, apply the brake and place the gearshift lever in
2004 Navigator (nav)
Owners Guide (post-2002-fmt)
USA English (fus)Driving
258

(Overdrive) for 10 seconds, then return the gearshift lever to P (Park)
and release the brake. With the ignition still in the ON position, and all
doors closed, allow the vehicle to stand (without passengers) for several
minutes so that it can level.
2. Turn the air suspension (if equipped) control to OFF.
3. Measure the height of a reference point on the front and rear bumpers
at the center of the vehicle.
4. Attach the trailer to the vehicle and adjust the hitch equalizers so that
the front bumper height is within 0 – 13 mm (0.5 in) of the reference
point. After proper adjustment, the rear bumper should be no higher
than in Step 3.
5. Turn the air suspension (if equipped) control to ON.
Note: Adjusting an equalizing hitch so the rear bumper of the vehicle is
higher than it was unloaded will defeat the function of the load
equalizing hitch and may cause unpredictable handling.
Safety chains
Always connect the trailer ’ s safety chains to the frame or hook retainers
of the vehicle hitch. To connect the trailer ’ s safety chains, cross the
chains under the trailer tongue and allow slack for turning corners.
If you use a rental trailer, follow the instructions that the rental agency
gives to you.
Do not attach safety chains to the bumper.
Trailer brakes
Electric brakes and manual, automatic or surge-type trailer brakes are
safe if installed properly and adjusted to the manufacturer ’ s
specifications. The trailer brakes must meet local and Federal
regulations.
Do not connect a trailer ’ s hydraulic brake system directly to your
vehicle ’ s brake system. Your vehicle may not have enough
braking power and your chances of having a collision greatly increase.
The braking system of the tow vehicle is rated for operation at the
GVWR not GCWR.
Trailer lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. See your
dealer or trailer rental agency for proper instructions and equipment for
hooking up trailer lamps.

Driving while you tow
When towing a trailer:
• Turn off the speed control. The speed control may shut off
automatically when you are towing on long, steep grades.
• Consult your local motor vehicle speed regulations for towing a trailer.
• To eliminate excessive shifting, use a lower gear. This will also assist
in transmission cooling. (For additional information, refer to the
Understanding the positions of the 4 – speed automatic
transmission section in this chapter.
• Anticipate stops and brake gradually.
• Do not exceed the GCWR rating or transmission damage may occur.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to your scheduled maintenance guide for
more information.
Trailer towing tips
• Practice turning, stopping and backing up before starting on a trip to
get the feel of the vehicle trailer combination. When turning, make
wider turns so the trailer wheels will clear curbs and other obstacles.
• Allow more distance for stopping with a trailer attached.
• If you are driving down a long or steep hill, shift to a lower gear. Do
not apply the brakes continuously, as they may overheat and become
less effective.
• The trailer tongue weight should be 10 – 15% of the loaded trailer
weight.
• After you have traveled 80 km (50 miles), thoroughly check your
hitch, electrical connections and trailer wheel lug nuts.
• To aid in engine/transmission cooling and A/C efficiency during hot
weather while stopped in traffic, place the gearshift lever in P (Park).
• Vehicles with trailers should not be parked on a grade. If you must
park on a grade, place wheel chocks under the trailer ’ s wheels.
Launching or retrieving a boat
Disconnect the wiring to the trailer before backing the trailer
into the water. Reconnect the wiring to the trailer after the
trailer is removed from the water.
