•Front crash severity sensors.
•Restraints control module with impact and safing sensors.
•Restraint system warning light and backup tone.
•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 direction indicator lamps and the horn sounds
(intermittently) in the event of a serious impact that deploys an airbag
equipped on your vehicle.
The horn and lamps turn off when:
•You press the hazard button.
•You press the panic button (if equipped) on the remote entry
transmitter.
•Your vehicle runs out of power.

Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to use electric trailer brakes.
Your vehicle may tow a trailer provided the maximum trailer weight is
less than or equal to the maximum trailer weight listed for your vehicle
configuration on the following chart.
To calculate the maximum loaded trailer weight for your vehicle:
1. Start with the gross combined weight rating for your vehicle model
and axle ratio. See the following chart.
2. Subtract all of the following that apply to your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such as a draw bar, ball, locks or weight
distributing
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggage weight
•Aftermarket equipment weight.
3. This equals the maximum loaded trailer weight for this combination.
Note:The trailer tongue load figures into the payload for your vehicle.
Reduce the total payload by the final trailer tongue weight.
Consult an authorized dealer to determine the maximum trailer weight
allowed for your vehicle if you are not sure.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive your vehicle at least 1000 miles
(1600 kilometers).
•Consult your local motor vehicle laws for towing a trailer.
•See the instructions included with towing accessories for the proper
installation and adjustment specifications.
•Service your vehicle more frequently if you tow a trailer. See your
scheduled maintenance information.
•If you use a rental trailer, follow the instructions the rental agency
gives you.
For load specification terms found on the tire label and Safety
Compliance label and for instructions on calculating your vehicle’s load,
refer toLoad limitin theLoad Carryingchapter.
Remember to account for the trailer tongue weight as part of your
vehicle load when calculating the total vehicle weight.
Trailer Towing Connector (Vehicles with a Trailer Towing Package
and 7–Pin Connector)
When attaching the trailer wiring
connector to your vehicle, only use
a proper fitting connector that
works with the vehicle and trailer
functions. If your vehicle has a
trailer towing package, it may have
a 7–pin connector. Some connectors
may have the SAE J2863 logo,
which confirms that it is the proper
wiring connector and works correctly with your vehicle.

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 if you use the manual control lever or make gain adjustments
with no trailer connected.
•TBC GAIN = XX.X OUTPUT=//////:Displays when you push
your vehicle’s brake pedal, or when you use the manual control. 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 indicate maximum output.
•TRAILER CONNECTED:Displays when the system senses a
correct trailer wiring connection (a trailer with electric trailer brakes)
during a given ignition cycle.
•TRAILER DISCONNECTED:Displays, accompanied by a single
audible chime, when the system senses a trailer connection and then
a disconnection, either intentional or unintentional, 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 if you use the manual control lever without a trailer
connected.
B.Manual control lever:Slide the control lever to the left to turn on
the trailer’s electric brakes independent of the tow vehicle’s brakes. See
the followingProcedure for adjusting gainsection for instructions on
proper use of this feature. If you use the manual control while the brake
is also applied, the greater of the two inputs determines the power sent
to the trailer brakes.
•Stop lamps:Using the manual control lever illuminates both the
trailer brake lamps and your vehicle brake lamps except the center
high-mount stop lamp, if you make the proper electrical connection
to the trailer. Pressing your vehicle brake pedal also illuminates both
trailer and vehicle brake lamps.

Procedure for Adjusting Gain
Note:Only perform this procedure in a traffic-free environment at
speeds of approximately 20–25 mph (30–40 km/h).
The gain setting sets the trailer brake controller for the specific towing
condition. You should change the setting as towing conditions change.
Changes to towing conditions include trailer load, vehicle load, road
conditions and weather.
The gain should be set to provide the maximum trailer braking assistance
while making sure the trailer wheels do not lock when using the brakes.
Locked trailer wheels may lead to trailer instability.
1. Make sure the trailer brakes are in good working condition,
functioning normally and properly adjusted. See your trailer dealer if
necessary.
2. Hook up the trailer and make the electrical connections according to
the trailer manufacturer’s instructions.
3. When you plug in a trailer with electric or electric-over-hydraulic
brakes,TRAILER CONNECTEDappears in the information display.
4. Use the gain adjustment (+ and -) 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 lock up, 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 lock-up. If towing a heavier trailer, trailer wheel lock-up
may not be attainable even with the maximum gain setting of 10.
Explanation of Information Display Warning Messages
Note:An authorized dealer can diagnose the trailer brake controller to
determine exactly which trailer fault has occurred. However, your Ford
warranty doesnotcover this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT:Displays in response to faults
sensed by the trailer brake controller, accompanied by a single chime. If
this message appears, contact an authorized dealer as soon as possible
for diagnosis and repair. The controller may still function, but
performance may be degraded.
WIRING FAULT ON TRAILER:Displays when there is a short circuit
on the electric brake output wire. If theWIRING FAULT ON TRAILER
message displays, accompanied by a single chime, with no trailer
