•a readiness light and tone
•a diagnostic module
•and the electrical wiring which connects the components
The diagnostic module monitors its own internal circuits and the
supplemental airbag electrical system wiring (including the impact
sensors), the system wiring, the airbag system readiness light, the airbag
back up power and the airbag ignitors.
WARNING:Several air bag system components get hot after
inflation. Do not touch them after inflation.
WARNING:If the air bag has deployed,the air bag will not
function again and must be replaced immediately.If the air
bag is not replaced, the unrepaired area will increase the risk of injury
in a collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument cluster or a tone to
indicate the condition of the system. Refer toAirbag readinesssection
in theInstrument Clusterchapter. Routine maintenance of the airbag is
not required.
A difficulty with the system is indicated by one or more of the following:
•The readiness light will either
flash or stay lit.
•The readiness light will not
illuminate immediately after ignition is turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and/or light are repaired.
If any of these things happen, even intermittently, contact your
authorized dealer as soon as possible. Unless serviced, the system may
not function properly in the event of a collision.
SOS Post-Crash Alert System™
The system automatically flashes the turn signal lamps and sounds the
horn three times at four second intervals in the event of a serious impact
that deploys an airbag (front, side, side curtain or Safety Canopy
)or
the safety belt pretensioners.

Note:
•If a double horn chirp is heard, repeat the procedure. If a single horn
chirp is not heard, move the vehicle to rotate the wheels at least a
14-turn and repeat the procedure starting with Step 1.
•If a double horn chirp is heard even after the wheels were
repositioned, contact your authorized dealer as soon as possible.
10. Perform Steps 8 and 9 on the right front tire, right rear tire and
finally the left rear tire. Training is complete after the horn sounds for
the last tire trained (left rear tire) and the message center displays:
TRAINING COMPLETE.
Turn the ignition to off. If two short horn beeps are heard, the reset
procedure was unsuccessful and must be repeated.
If after repeating the procedure and two short beeps are heard when the
ignition is turned to off, contact your authorized dealer as soon as
possible.
SNOW TIRES AND 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.
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:
•Use only SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.

smooth and effective trailer braking by powering the trailer’s electric
brakes with a proportional output based on the towing vehicle’s brake
pressure.
WARNING:The Ford TBC has only been verified to be
compatible with trailers having electric-actuated drum brakes
(one to four axles) and not hydraulic surge or electric-over-hydraulic
types. It is the responsibility of the customer to ensure that the trailer
brakes are adjusted appropriately, functioning normally and all electric
connections are properly made.
The TBC user interface consists of
the following:
1.+/- (GAIN adjustment
buttons):Pressing these buttons
will adjust 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 will raise or lower the setting continuously. The gain
setting will display in the message center as follows: TBC GAIN = XX.X.
The trailer brake controller (TBC) is designed to display three items of
information in the instrument cluster message center. These are: gain
setting, output bar graph, and trailer connectivity status. They will
appear as follows in the message center.
•TBC GAIN = XX.X NO TRAILER: The instrument cluster message
center will display the current gain setting during a given ignition
cycle and when adjusting the gain. This message is also displayed
during manual activation without a trailer connected or when gain
adjustments are made with no trailer connected.
•TBC GAIN = XX.X OUTPUT = //////: When the vehicle’s brake pedal
is pushed, or when the manual control is activated, bar indicators will
illuminate in the instrument cluster message center 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
with six bars indicating maximum output.
•TRAILER CONNECTED:This message is displayed when a correct
trailer wiring connection (a trailer with electric trailer brakes) has
been sensed during a given ignition cycle.

•TRAILER DISCONNECTED:This message is displayed and
accompanied by a single chime, 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 truck or trailer wiring fault occurs causing the trailer to
appear disconnected. This message is also displayed during manual
activation without a trailer connected.
2.Manual control lever:Slide the control lever to the left to activate
power to 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 the manual control is
activated while the brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
•Stop Lamps:Activating the TBC manual control lever will illuminate
both the trailer brake lamps and the tow vehicle brake lamps except
the Center High-Mount Stop Lamp (presuming proper trailer electrical
connection). Pressing the vehicle brake pedal will also illuminate both
trailer and vehicle brake lamps.
Procedure for adjusting GAIN:
The GAIN setting is used to set the TBC for the specific towing
condition and should be changed 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 ensuring the trailer wheels do not lock when braking.
Locked trailer wheels may lead to trailer instability.
Note:This should only be performed in a traffic free environment at
speeds of approximately 20–25 mph (30–40 km/h).
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 a trailer with electric brakes is plugged in, theTRAILER
CONNECTEDmessage will display in the instrument cluster message
center.
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 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 lockup may
not be attainable even with the maximum GAIN setting of 10.
Explanation of instrument cluster warning messages:
The TBC interacts with the instrument cluster message center to display
the following messages:
TRAILER BRAKE MODULE FAULT: This message is displayed and
accompanied by a single chime, in response to faults sensed by the TBC.
In the event this message is seen, 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: This message is displayed when a
Short circuit on the electric brake output wirehas occurred. If the
WIRING FAULT ON TRAILERmessage is displayed and accompanied
by a single chime, 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., 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.

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.
All 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.
