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 authorized dealer (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.

Note:For vehicles not equipped with the optional trailer tow package,
the maximum frontal area of trailer should not exceed the frontal area
of the vehicle (3.4 square meters [36.5 square feet]).
Note:For vehicles equipped with the optional trailer tow package, the
maximum frontal area of trailer should not exceed 5.6 square meters
(60 square feet).
Do not exceed the maximum loads listed on the Safety Compliance
Certification label. For load specification terms found on the label, refer
toVehicle loadingin this chapter. Remember to figure in the tongue
load of your loaded trailer when figuring the total weight.
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.

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.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. See your authorized 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
(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 a
1 2” (13 mm) 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
authorized 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

Understanding the gearshift positions of the 4–speed automatic
transmissionin theDriving chapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
If your vehicle is equipped with AdvanceTracwith RSC, you may
experience AdvanceTracwith RSC activations during typical cornering
maneuvers with a heavily loaded trailer; this is normal. Cornering at a
slower speed while towing will reduce the tendency of the AdvanceTrac
stability enhancement system to activate.
Servicing after towing
If you tow a trailer for long distances, your vehicle will require more
frequent service intervals. Refer to yourScheduled Maintenance
Informationfor 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 50 miles (80 km), 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.
When backing down a ramp during boat launching or retrieval:
•do not allow the static water level to rise above the bottom edge of
the rear bumper.

•do not allow waves to break higher than 6 inches (15 cm) above the
bottom edge of the rear bumper.
Exceeding these limits may allow water to enter vehicle components:
•causing internal damage to the components.
•affecting driveability, emissions and reliability.
Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
An example of recreational towing would be towing your vehicle behind
a motorhome. Follow these guidelines if you have the need for
recreational towing your vehicle with all four wheels on the ground.
These guidelines are designed to ensure that your transmission is not
damaged.
2WD vehicles (with automatic transmissions):
•Place the transmission in N (Neutral)
•Maximum speed is 35 mph (56 km/h)
•Maximum distance is 50 miles (80 km)
If a distance of 50 miles (80 km) or a speed of 35 mph (56 km/h) must
be exceeded, the drive shaft will have to be removed before the vehicle
is towed.
Ford recommends the driveshaft be removed/installed only by a qualified
technician at an authorized dealer. See your authorized dealer for
driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
Vehicles equipped with Control Trac four-wheel drive system:
Vehicles equipped with the Control Trac four-wheel drive system cannot
be towed with any wheels on the ground. See your authorized dealer if
you must flat-tow a vehicle equipped with the Control Trac four-wheel
drive system.

Towingin this chapter)
The RSC feature works to further enhance the vehicle’s overall stability
during aggressive maneuvers. The RSC feature helps maintain roll
stability of the vehicle during aggressive maneuvers by applying brake
force to one or more wheels.
The AdvanceTracwith RSC system automatically turns on when the
engine is started. However, the system does not function when the
vehicle is traveling in R (Reverse) or, if equipped with four-wheel drive,
in 4L (4X4 LOW). In R (Reverse) or in 4L (4X4 LOW), ABS and the
traction enhancement feature will continue to function.
The AdvanceTracwith RSC button,
located on the center console,
allows the driver to control the
availability of the AdvanceTrac
with RSC system. The RSC 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
“ADVANCETRAC OFF” will be displayed.
If a failure is detected in the AdvanceTracwith RSC 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 by an authorized dealer
immediately.
Pressing the button once will disable the AdvanceTracwith RSC
stability enhancement system 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 AdvanceTracwith
RSC stability enhancementandtraction enhancement feature. If the
vehicle is stuck in snow or mud or when driving in deep sand, switching
off the AdvanceTracwith RSC 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 AdvanceTrac
with RSC stability enhancement system will restore full engine power
and will enhance momentum through the obstacle.

air suspension system will stay active for 40 minutes after the ignition is
turned off to accommodate any load changes. (The air compressor may
run when the vehicle is off; this is normal.)
The air suspension shut-off switch is
located behind an access panel on
the left rear quarter trim panel, near
the liftgate. To remove the panel,
turn the control counterclockwise.
On vehicles equipped with
air suspension, turn the air
suspension and the ignition switch
off prior to jacking, hoisting or
towing your vehicle.
Press the bottom portion of the
switch to turn off the air
suspension.
LIMITED-SLIP AXLE (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
limited slip axle functions like a standard rear axle.
