•The electrical wiring for the airbags, crash sensor(s), safety belt
pretensioners, front safety belt usage sensors, driver seat position
sensor, and indicator lights.
How does the Restraint Safety System work?
The Restraint Safety System can adapt the deployment strategy of your
vehicle’s safety devices according to crash severity and occupant
conditions. A collection of crash and occupant sensors provides
information to the restraints control module. During a crash, the
restraints control module may activate the safety belt pretensioners
and/or either one or both stages of the dual-stage airbag supplemental
restraints based on crash severity and occupant conditions.
SOS POST-CRASH ALERT SYSTEM™
The system flashes the turn signal lamps and sounds the horn
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle, such as front, side, side curtain or Safety
Canopy.
The horn and lamps will turn off when:
•the hazard control button is pressed
•the panic button (if equipped) is pressed on the remote entry
transmitter, or
•your vehicle runs out of power.
DRIVER AND PASSENGER AIRBAGS
WARNING:Never place your arm or any objects over an airbag
module. Placing your arm over a deploying airbag can result in
serious arm fractures or other injuries. Objects placed on or over the
airbag inflation area may cause those objects to be propelled by the
airbag into your face and torso causing serious injury.
WARNING:Airbags can kill or injure a child in a child seat.
Never place a rear-facing child seat in front of an active airbag. If
you must use a forward-facing child seat in the front seat, move the
seat all the way back.

This feature applies the vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes and the messageTRAILER SWAY
REDUCE SPEEDappears in the information display. The first thing to
do is slow the vehicle down, then pull safely to the side of the road and
check for proper tongue load and trailer load distribution. See theLoad
Carryingchapter for specific loading information.
RECOMMENDED TOWING WEIGHTS
Note:Do not exceed the trailer weight for your vehicle configuration
listed in the chart below.

The TBC user interface consists of the following:
A.+/- (GAIN adjustment buttons):Pressing these buttons adjusts the
TBC’s power output to the trailer brakes (in 0.5 increments). The GAIN
setting can be increased to a maximum of 10.0 or decreased to a
minimum of 0 (no trailer braking). Pressing and holding a button raises
or lowers the setting continuously. The GAIN setting displays in the
message center as follows: TBC GAIN = XX.X.
The controller is designed to display three items of information in the
information display. These are: GAIN setting, output bar graph, and
trailer connectivity status. They appear in the information display as
follows:
•TBC GAIN = XX.X NO TRAILER:Shows the current GAIN setting
during a given ignition cycle and when adjusting the GAIN. This also
displays during manual activation without a trailer connected or when
GAIN adjustments are made with no trailer connected.
•TBC GAIN = XX.X OUTPUT=//////:Displays when the vehicle’s
brake pedal is pushed, or when the manual control is activated. Bar
indicators illuminate in the information display to indicate the amount
of power going to the trailer brakes relative to the brake pedal or
manual control input. One bar indicates the least amount of output;
six bars indicates maximum output.
•TRAILER CONNECTED:Displays when a correct trailer wiring
connection (a trailer with electric trailer brakes) has been sensed
during a given ignition cycle.
•TRAILER DISCONNECTED:Displays, accompanied by a single
audible chime, when a trailer connection was determined and then a
disconnection (either intentionally or unintentionally), has been
sensed during a given ignition cycle. It also displays if a truck or
trailer wiring fault occurs causing the trailer to appear disconnected.
This message can also display during manual activation without a
trailer connected.

Explanation of Information Display Warning Messages
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.
TRAILER BRAKE MODULE FAULT:Displays in response to faults
sensed by the TBC (accompanied by a single chime). If this message is
displayed, please contact your authorized dealer as soon as possible for
diagnosis and repair. The TBC may still function, but performance may
be degraded.
WIRING FAULT ON TRAILER:Displays when a short circuit on the
electric brake output wire has occurred. If theWIRING FAULT ON
TRAILERmessage is displayed and accompanied by a single chime,
with no trailer connected, the problem is with the vehicle wiring between
the TBC to the 7–pin connector at 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), short to voltage (i.e., pulled pin on trailer
emergency break-away battery) or the trailer brakes may be drawing too
much current.
Points to Remember
Note:Do not attempt removal of the TBC without consulting the
Workshop Manual.Damage to the unit may result.
•Adjust GAIN setting before using the TBC for the first time.
•Adjust GAIN setting (according to procedure above) whenever road,
weather and trailer or vehicle loading conditions change from when
the GAIN was initially set.
•The manual control lever should only be used for proper adjustment
of the GAIN during trailer setup. Misuse, such as application during
trailer sway, could cause instability of trailer or tow vehicle.
•Avoid towing in adverse weather conditions. The TBC does not
provide anti-lock control of the trailer wheels. Trailer wheels can lock
up on slippery surfaces, resulting in reduced stability of trailer and
tow vehicle.
•The TBC is equipped with a feature which reduces output at vehicle
speeds below 11 mph (18 km/h) so trailer and vehicle braking is not
jerky or harsh. This feature is only available when applying the brakes
using the vehicle’s brake pedal, not the TBC.
•The controller interacts with the brake control system and powertrain
control system of the vehicle to provide the best performance on
different road conditions.

•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 reduces the tendency of the
AdvanceTrac™ stability enhancement system to activate.
•If you are 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 lubricant, if not already so
equipped. See theCapacities and Specificationschapter for the
lubricant specification.
•Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.
•Avoid parking on a grade. However, if you must park on a grade:
1. Turn the steering wheel to point the vehicle tires away from
traffic flow.
2. Set the vehicle parking brake.
3. Place the automatic transmission in positionPor manual
transmission in a high gear.
4. Place wheel chocks in front and back of the trailer wheels.
(Chocks not equipped with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer other
than the road tires on your vehicle, your spare tire is considered
“temporary”. Consult information on the tire label or Safety Compliance
label for limitations when using.
Launching or Retrieving a Boat or Personal Watercraft (PWC)
Note:Disconnect the wiring to the trailerbeforebacking the trailer into
the water.
Note: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 centimeters)
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.

USING SNOW CHAINS
WARNING:Snow tires must be the same size, load index, speed
rating as those originally provided by Ford. Use of any tire or
wheel not recommended by Ford can affect the safety and performance
of your vehicle, which could result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and death. Additionally, the use
of non-recommended tires and wheels could cause steering, suspension,
axle or transfer case/power transfer unit failure.
Note:The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when using
snow tires and chains.
The tires on your vehicle have all-weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•If possible, avoid fully loading your vehicle.
•Use only cable type chains or chains offered by Ford as an accessory
or equivalent. Other conventional link type chains may contact and
cause damage to the vehicle’s wheel house and/or body.
•Do not install chains on the front wheels as this may interfere with
suspension components.
•Chains are not recommended for use on the P275/55R20 tire.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Do not exceed 30 mph (48 km/h) with tire chains on your vehicle.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and retighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
•Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
