trailer LINCOLN NAVIGATOR 2004 User Guide

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.

If the vehicle is towed by other means or incorrectly, vehicle
damage may occur.
With a disabled vehicle (without access to wheel dollies, car hauling
trailer or flatbed transport vehicle) your vehicle can be towed (all wheels
on the ground) under the following conditions:
Special Conditions:
• Release the parking brake.
• Turn the air suspension control to OFF.
• Turn the ignition to the OFF/UNLOCKED position.
• Place the transmission in N (Neutral).
If the vehicle ’ s battery is discharged, refer to Automatic transmission
operation in the Driving chapter for directions on how to move the
gearshift lever out of the P (Park) position, for proper towing.
• Do not exceed a distance of 80 km (50 miles).
• Do not exceed 56 km/h (35 mph) vehicle speed.
Ford Motor Company produces a towing manual for all authorized tow
truck operators. Have your tow truck operator refer to this manual for
proper hook-up and towing procedures for your vehicle.
