2. To reinstall the cover, insert the
four plastic tabs on top of the cover
into the corresponding 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
14-turn
fasteners by turning them clockwise.
Preparing to tow
Use the proper equipment for towing a trailer and make sure it is
properly attached to your vehicle. Contact your authorized dealer or a
reliable trailer dealer as soon as possible if you require assistance.
Hitches
Do not use hitches that clamp onto the vehicle bumper. Use a load
carrying hitch. You must distribute the load in your trailer so that
10%–15% of the total weight of the trailer is on the tongue.
WARNING:The trailer hitch on this vehicle is part of the
vehicle rear crash safety structure. Do not remove the trailer
hitch. Failure to follow this warning could compromise vehicle crash
structure and increase the risk of injury in a rear end collision.
Weight distributing 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 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.

Driving while you tow
When towing a trailer:
•Keep your speed no faster than 70 mph (113 km/h) during the first
500 miles (800 km) of towing a trailer, and don’t make full throttle
starts.
•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 toAutomatic
transmission operationin theDrivingchapter.
•Anticipate stops and brake gradually.
•Do not exceed the GCWR rating or transmission damage may occur.
If your vehicle is equipped with AdvanceTrac
with RSC, you may
experience AdvanceTrac
with 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.

•If you will be towing a trailer frequently in hot weather, hilly
conditions, at GCWR, or any combination of these factors, consider
refilling your rear axle with synthetic gear lube if not already so
equipped. Refer to theMaintenance and Specificationschapter for
the lubricant specification. Remember that regardless of the rear axle
lube used, do not tow a trailer for the first 1,000 miles (1,600 km) of a
new vehicle, and that the first 500 miles (800 km) of towing be done
at no faster than 70 mph (113 km/h) with no full throttle starts.
•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
Follow these guidelines if you have a need for recreational towing. An
example of recreational towing would be towing your vehicle behind a
motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
Note:Put your climate control system in recirculated air mode to
prevent exhaust fumes from entering the vehicle. Refer to theClimate
controlschapter for more information.
2WD vehicles:Do not tow your vehicle with any wheels on the ground,
as vehicle or transmission damage may occur. It is recommended to tow
your vehicle with all four (4) wheels off the ground such as when using a
car-hauling trailer. Otherwise, no recreational towing is permitted.
In case of a roadside emergency with a disabled vehicle, seeWrecker
towingin theRoadside Emergencieschapter.
4WD vehicles (Control Trac four-wheel drive system):Do not tow
your vehicle with any wheels on the ground, as vehicle or transmission
damage may occur. It is recommended to tow your vehicle with all four
(4) wheels off the ground such as when using a car-hauling trailer.
Otherwise, no recreational towing is permitted. See your authorized
dealer if you must flat-tow a vehicle equipped with the Control Trac
four-wheel drive system.

Electronic Stability Control (ESC)
Electronic Stability Control (ESC) may enhance your vehicle’s directional
stability during adverse maneuvers, for example when cornering severely
or avoiding objects in the roadway. ESC operates by applying brakes to
one or more of the wheels individually and, if necessary, reducing engine
power if the system detects that the vehicle is about to skid or slide
laterally.
During Electronic Stability Control events the “sliding car” icon
in the
instrument cluster will flash.
Certain adverse driving maneuvers may activate the Electronic Stability
Control system, which include but are not limited to:
•Taking a turn too fast
•Maneuvering quickly to avoid an accident, pedestrian or obstacle
•Driving over a patch of ice or other slippery surfaces
•Changing lanes on a snow-rutted road
•Entering a snow-free road from a snow-covered side street, or vice
versa
•Entering a paved road from a gravel road, or vice versa
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter).
Roll Stability Control™ (RSC
)
Roll Stability Control™ (RSC
) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSC
operates by detecting the
vehicle’s roll motion and the rate at which it changes and by applying the
brakes to one or more wheels individually.
During an event that activates the Roll Stability Control™ (RSC
)the
“sliding car” icon
in the instrument cluster will flash.
Certain adverse driving maneuvers may activate the Roll Stability Control
system, which include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle

Switching Off Traction Control
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off the Traction Control feature of the AdvanceTrac

with RSC
system may be beneficial because the wheels are allowed to
spin. This will restore full engine power and will enhance momentum
through the obstacle. To switch off the Traction Control feature press the
AdvanceTrac
with RSC
Offbutton. Full features of the AdvanceTrac

with RSC
system can be restored by pressing the AdvanceTrac
with
RSC
“Off” button again or by turning off and restarting the engine.
If you switch off the Traction Control, the sliding caricon
will
illuminate steadily. Pressing the AdvanceTrac
with RSC
“Off” button
again will turn off the “sliding car” icon
.
In R (Reverse), ABS and the Engine and Brake Traction Control features
will continue to function; however, ESC and RSC
are disabled.

Trailer Sway Control
Your vehicle may be equipped with trailer sway control. When properly
equipped, trailer sway control will use the vehicle’s AdvanceTrac
with
RSC
system to detect and help reduce trailer sway by applying brake
force at individual wheels and, if necessary, by reducing engine power.
WARNING:Trailer sway control does not prevent a trailer from
swaying, it mitigates the sway from increasing once it has
occurred. If you are experiencing trailer sway it is likely that the trailer
is improperly loaded for the correct tongue weight or the speed of the
vehicle and trailer is too high. Pull the vehicle-trailer over to a safe
location to check the trailer weight distribution and tongue load and
reduce speed to a safe level while towing. If trailer sway is
experienced, SLOW DOWN.

During trailer sway control events the “sliding car”icon in the
instrument cluster will flash momentarily. The cluster message center
will also displayTRAILER SWAY REDUCE SPEED. In some cases
when trailer sway is detected, the vehicle speed is too high and may be
above a speed at which trailer sway will not grow continuously. This may
cause the system to activate multiple times, causing a gradual reduction
in speed.
Note:The trailer sway control will only activate at speeds greater than
40 mph (64 km/h).
Disabling Trailer Sway Control
Trailer sway control can be disabled during any key cycle. SeeMessage
centerin theInstrument Clusterchapter. Note that regardless of
chosen enable state, trailer sway control will be re-enabled at each new
key cycle.
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury, or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (e.g., hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering the vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
•Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the MAX mark on
the reservoir, as this may result in leaks from the reservoir.

the system determines that the vehicle is low or high and needs to make
a height adjustment while driving at speeds above 15 mph (24 km/h), the
system will pump or vent as required. Normal vehicle operation does not
require any action by the driver.
WARNING:On vehicles equipped with air suspension, turn the
air suspension and the ignition switch off prior to jacking,
hoisting or towing your vehicle.
PREPARING TO DRIVE
WARNING:Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING:In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a seat belt.
Utility vehicles and trucks have larger tires and increased ground
clearance, giving the vehicle a higher center of gravity than a passenger
car.
WARNING:Vehicles with a higher center of gravity such as
utility vehicles and trucks handle differently than vehicles with a
lower center of gravity. Utility vehicles and trucks arenotdesigned for
cornering at speeds as high as passenger cars any more than low-slung
sports cars are designed to perform satisfactorily under off-road
conditions. Avoid sharp turns, excessive speed or abrupt maneuvers in
these vehicles. Failure to drive cautiously could result in an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death.
WARNING:Loaded vehicles, with a higher center of gravity,
may handle differently than unloaded vehicles. Do not overload
your vehicle and use extra precautions, such as driving at slower
speeds, avoiding abrupt steering changes and allowing for increased
stopping distance, when driving a heavily loaded vehicle. Over-loading
or loading the vehicle improperly can deteriorate handling capability
and contribute to loss of vehicle control and vehicle rollover.

D (Overdrive) with Tow/Haul On
The Tow/Haul feature improves
transmission operation when towing
a trailer or a heavy load. All
transmission gear ranges are
available when using Tow/Haul.
To activate Tow/Haul, press the
button on the side of the gearshift
lever.
The TOW HAUL indicator light will
illuminate in the instrument cluster.
Tow/Haul delays upshifts to reduce frequency of transmission shifting.
Tow/Haul also provides engine braking in all forward gears when the
transmission is in the D (Overdrive) position; this engine braking will
slow the vehicle and assist the driver in controlling the vehicle when
descending a grade. Depending on driving conditions and load
conditions, the transmission may downshift, slow the vehicle and control
the vehicle speed when descending a hill, without the accelerator pedal
being pressed. The amount of downshift braking provided will vary based
upon the amount the brake pedal is depressed.
To deactivate the Tow/Haul feature and return to normal driving mode,
press the button on the end of the gearshift lever. The TOW HAUL light
will no longer be illuminated.
When you shut-off and restart the engine, the transmission will
automatically return to normal D (Overdrive) mode (Tow/Haul OFF).
WARNING:Do not use the Tow/Haul feature when driving in icy
or slippery conditions as the increased engine braking can cause
the rear wheels to slide and the vehicle to swing around with the
possible loss of vehicle control.

Use the side mirrors and rearview mirror to get better coverage on both
sides and rear of the vehicle.
Image delay if displayed through the rearview mirror:
When shifting out of R (Reverse) and into any other gear, the image in
the rearview mirror will remain on for a few seconds before it shuts off
to assist in parking or trailer hookup.
Image delay if displayed through the Navigation screen:
After shifting out of R (Reverse) and into any gear other than P (Park),
the image in the navigation screen will remain until the vehicle speed
reaches five mph (8 km/h), only if the rear camera delay feature is on, or
until any navigation radio button is pressed.
Note:The default setting for the camera delay is off. Press the
“Settings” button found on the navigation screen (if equipped) to set the
camera delay feature to on or off.
When towing, the camera system will only see what is being towed
behind the vehicle; this might not provide adequate coverage as it
usually provides in normal operation and some objects might not be
seen.
The camera lens for the camera is located on the liftgate, above the
license plate. Keep the lens clean so the video image remains clear and
undistorted. Clean the lens with a soft, lint-free cloth and non-abrasive
cleaner.
Note:If the camera system image is not clear or seems distorted, it may
be covered with water droplets, snow, mud or any other substance. If
this occurs, clean the camera lens before using the reverse camera
system.
WARNING:The camera system is a reverse aid supplement
device that still requires the driver to use it in conjunction with
the rearview mirror and the side mirrors for maximum coverage.
WARNING:Objects that are close to either corner of the
bumper or under the bumper, might not be seen on the screen
due to the limited coverage of the camera system.
WARNING:Backup as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.
