2009 FORD F150 trailer

4. Use the GAIN adjustment (+/–) buttons to increase or decrease the
GAIN setting to the desired starting point. A GAIN setting of 6.0 is a
good starting point for heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at
a speed of 20–25 mph (30–40 km/h) and squeeze the manual control
lever completely.
6. If the trailer wheels lockup (indicated by squealing tires), reduce the
GAIN setting; if the trailer wheels turn freely, increase the GAIN setting.
Repeat Steps 5 and 6 until the GAIN setting is at a point just below
trailer-wheel lockup. If towing a heavier trailer, trailer wheel lockup
may not be attainable even with the maximum GAIN setting of 10.
Explanation of instrument cluster messages:
The TBC interacts with the instrument cluster message center. These
messages, accompanied by a single chime, will be displayed when the
TBC determines a malfunction in the trailer connection, TBC system, or
in the trailer. These messages are listed below:
TRAILER DISCONNECTED (if equipped with message center):
This message is displayed when a trailer connection was determined and
then a disconnection, either intentionally or unintentionally, has been
sensed during a given ignition cycle. It is also displayed if a trailer fault
occurs causing the trailer to appear disconnected. This message is also
displayed during manual activation without a trailer connected.
TRAILER BRAKE MODULE FAULT: This message is displayed in
response to faults sensed by the TBC. In the event this message is seen,
please take your vehicle to an authorized dealer for diagnosis and repair.
The TBC may still function, but performance may be degraded.
WIRING FAULT ON TRAILER: The TBC is capable of determining
certain faults in the vehicle wiring and trailer wiring/brake system. These
faults do not mean there is anything wrong with the TBC. This message
is displayed when one of the following faults has occurred:
•Short circuit on the electric brake output wire:If theWIRING
FAULT ON TRAILERmessage is displayed with no trailer connected,
the problem is with the vehicle wiring from the TBC to the 7–pin
connector in the bumper. If the message is only displayed with a
trailer connected, the problem is related to the trailer wiring; consult
your trailer dealer for assistance. This can be a short to ground (i.e.,
chaffed wire) or a short to voltage (i.e., a pulled pin on trailer
emergency break-away battery) or trailer brakes drawing too much
current.

Note:Your TBC can be diagnosed by your authorized dealer to
determine exactly which trailer fault has occurred; however, if the fault
is with the trailer this diagnosis isnotcovered under your Ford
warranty.
Points to Remember:
•Remember to adjust gain setting before using the TBC for the first
time.
•Readjust GAIN setting on the TBC (according to procedure above)
whenever road, weather and trailer or vehicle loading conditions
change from those that existed when the gain was initially set.
•The sliding lever on the TBC should be used only for manual
activation of trailer brakes to assist with proper adjustment of the
GAIN. Misuse, such as application during trailer sway, could cause
instability of trailer and/or tow vehicle.
•Avoid towing in adverse weather conditions. The TBC does not
provide anti-lock control of the trailer wheels. Trailer wheels can
lockup on slippery surfaces, resulting in reduced stability of trailer and
tow vehicle.
•The TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lockup.
Therefore, if these systems are not functioning properly the TBC may
not function at full performance.
•When the vehicle is turned off, the TBC Output is disabled and the
display is shut down. Reactivation of the ignition from off to on will
awaken the TBC module.
•The TBC is only a factory or dealer installed item. Ford is not
responsible for warranty or performance of the TBC due to misuse or
customer installation.
•Do not attempt removal of the TBC without consulting the
Workshop Manual.Damage to the unit may result.
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.

Using a step bumper (if equipped)
The rear bumper is equipped with an integral hitch and only requires a
ball with a one inch (25.4 mm) shank diameter. The bumper has a
5,000 lb (2,270 kg) trailer weight and 500 lb (227 kg) tongue weight
capacity.
If it is necessary to relocate the trailer hitch ball position, a
frame-mounted trailer hitch must be installed.
Driving while you tow
When towing a trailer:
•To ensure proper “break-in” of powertrain components, do not trailer
tow during the first 1,000 miles (1,600 km) of a new vehicle.
•To ensure proper “break-in” of powertrain components during the first
500 miles (800 km) of trailer towing, drive no faster than 70 mph
(113 km/h) with no 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.
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. Also, see the information on tow/haul mode operation
underAutomatic transmission operationin theDrivingchapter.

•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 (RV) 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.
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.
4WD vehicles equipped with manual-shift transfer case:
•Release the parking brake.
•Turn the key in the ignition to the off position.
•Place the transmission in N (Neutral).
•Place the transfer case lever in N (Neutral).
•The maximum recommended distance is unlimited.
•The vehicle must be towed in the forward position to ensure no
damage is done to the internal transfer case components.
The transfer case N (Neutral) position overrides the transmission and
puts the vehicle in neutral regardless of transmission gearshift lever
position. The vehicle can move forward or backward. This position
should only be used when towing the vehicle.
WARNING:Do not leave the vehicle unattended with the
transfer case in the N (Neutral) position. Always set the parking
brake fully and turn off the ignition when leaving the vehicle.
After reaching the destination, you must place your vehicle’s 4x4
gearshift lever in gear (2H, 4H or 4L).
In case of a roadside emergency with a disabled vehicle, seeWrecker
towingin theRoadside Emergencieschapter.
4WD vehicles equipped with an electronic-shift transfer case: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

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).
The Electronic Stability Control system may be deactivated in certain
situations. See theSwitching Off AdvanceTracwith RSCsection
following.
Roll Stability Control™ (RSC)
Roll Stability Control (RSC) may help to maintain roll stability of the
vehicle during adverse maneuvers. RSCoperates 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
The Roll Stability Control system may be deactivated in certain situations.
See theSwitching Off AdvanceTracwith RSCsection following.
Switching Off AdvanceTracwith RSC
If the vehicle is stuck in snow, mud or sand, and seems to lose engine
power, switching off certain features of the AdvanceTracwith 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 AdvanceTracwith RSCsystem press the
AdvanceTracwith RSCOffbutton. Full features of the AdvanceTrac
with RSCsystem can be restored by pressing the AdvanceTracwith
RSCOffbutton again or by turning off and restarting the engine.

equipped, trailer sway control will use the vehicle’s AdvanceTracwith
RSCsystem 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 theskidding 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. See Trailer
Sway Control under theMessage centerin theDriver Controlschapter.
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
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering fluid level
(below the MIN mark on the reservoir).
