WARNING: If the Safety Canopy system has deployed, the
Safety Canopy will not function again unless replaced. The
Safety Canopy system (including the A, B, C, and D pillar trim and
headliner) must be inspected and serviced by an authorized dealer. If
the Safety Canopy is not replaced, it will not function again, which will
increase the risk of injury in a future 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 to Warning lights and
chimes in the Instrument Cluster chapter. Routine maintenance of the
side airbag is not required.
A difficulty with the system is indicated by one or more of the following:
• The readiness light (same light as for front airbag system) 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, have the SRS serviced
at your authorized dealer immediately. 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 [if equipped] or Safety
Canopy [if equipped]) or the safety belt pretensioners.
The system can be turned off when any one of the following actions are
taken by the driver or any other person:
• pressing the hazard control button,
• or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power. Seating and Safety Restraints

switch is in on, have the passenger airbag switch serviced at your
authorized dealer immediately.
The passenger side airbag should always be ON (the “pass airbag off”
light should not be illuminated) unless the passenger is a person who
meets the requirements stated either in Category 1, 2 or 3 of the
NHTSA/Transport Canada deactivation criteria which follows.
WARNING: The safety belts for the driver and right front
passenger seating positions have been specifically designed to
function together with the airbags in certain types of crashes. When
you turn OFF your airbag, you not only lose the protection of the
airbag, you also may reduce the effectiveness of your safety belt
system, which was designed to work with the airbag. If you are not a
person who meets the requirements stated in the NHTSA/Transport
Canada deactivation criteria turning OFF the airbag can increase the
risk of serious injury or death in a collision. Seating and Safety Restraints

TPMS reset procedure
The TPMS reset procedure needs to be performed after each tire
rotation on vehicles that require different recommended tire
pressures in the front tires as compared to the rear tires.
WARNING: To determine the required pressure(s) for your
vehicle, refer to the Safety Compliance Certification Label or
Tire Label located on the B-Pillar or the edge of the driver’s door. See
Vehicle loading - with and without a trailer in this chapter for more
information.
Overview
To provide the vehicle’s load carrying capability, some vehicles require
different recommended tire pressures in the front tires as compared to
the rear tires. The tire pressure monitoring system (TPMS) equipped on
these vehicles is designed to illuminate the low tire pressure warning
light at two different pressures; one for the front tires and one for the
rear tires.
Since tires need to be rotated to provide consistent performance and
maximum tire life, the tire pressure monitoring system needs to know
when the tires are rotated to determine which set of tires are on the
front and which are on the rear. With this information, the system can
detect and properly warn of low tire pressures.
TPMS reset tips:
• To reduce the chances of interference from another vehicle, the TPMS
reset procedure should be performed at least three feet (one meter)
away from another Ford Motor Company vehicle undergoing the TPMS
reset procedure at the same time.
• Do not wait more than two minutes between resetting each tire sensor
or the system will time-out and the entire procedure will have to be
repeated on all four wheels.
• A double horn chirp indicates the need to repeat the procedure.
Performing the TPMS reset procedure
It is recommended that you read the entire procedure before attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes
and then park in a safe location where you can easily get to all four tires
and have access to an air pump.
2. Place the ignition in the off position and keep the key in the ignition. Tires, Wheels and Loading

3. Cycle the ignition to the on
position with the engine off.
4. Turn the hazard flashers on then
off three times. This must be
accomplished within 10 seconds.
If the reset mode has been entered successfully, the horn will sound
once, the TPMS indicator will flash and the message center (if
equipped) will display TRAIN LEFT FRONT TIRE . If this does not
occur, please try again starting at Step 2.
If after repeated attempts to enter the reset mode, the horn does not
sound, the TPMS indicator does not flash and the message center (if
equipped) does not display TRAIN LEFT FRONT TIRE , seek service
from your authorized dealer.
5. Train the TPMS sensors in the tires using the following TPMS reset
sequence starting with the left front tire in the following clockwise
order:
• Left front (Driver’s side front tire)
• Right front (Passenger’s side front tire)
• Right rear (Passenger’s side rear tire)
• Left rear (Driver’s side rear tire)
6. Remove the valve cap from the valve stem on the left front tire;
decrease the air pressure until the horn sounds.
Note: The single horn chirp confirms that the sensor identification code
has been learned by the module for this position. If a double horn is
heard, the reset procedure was unsuccessful, and must be repeated.
7. Remove the valve cap from the valve stem on the right front tire;
decrease the air pressure until the horn sounds.Tires, Wheels and Loading

8. Remove the valve cap from the valve stem on the right rear tire;
decrease the air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire;
decrease the air pressure until the horn sounds.
Training is complete after the horn sounds for the last tire trained
(driver’s side rear tire), the TPMS indicator stops flashing, and the
message center (if equipped) displays:
TRAINING COMPLETE .
10. Turn the ignition 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, seek assistance from your authorized dealer.
11. Set all four tires to the recommended air pressure as indicated on
the Safety Compliance Certification Label or Tire Label located on the
B-Pillar or the edge of the driver’s door. See Vehicle loading - with and
without a trailer in this chapter for more information.
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.
Note: Do not use snow chains on vehicles with 20 inch wheels and tires.
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.
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. Tires, Wheels and Loading

The TBC user interface consists of
the following:
1. +/- (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 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 appear in
the message center as follows:
• TBC GAIN = XX.X NO TRAILER: The instrument cluster message
center displays 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
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. Tires, Wheels and Loading

• 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 TBC interacts with the brake system of the vehicle, including
ABS, in order to reduce the likelihood of trailer wheel lock-up;
therefore, if these systems are not functioning properly, the TBC may
not function at full performance.
• Your vehicle’s brake system and the trailer brake system work
independently of each other; changing the GAIN setting on the TBC
does not affect the operation of your vehicle’s brakes whether a trailer
is attached or not.
• When the vehicle is turned off, the TBC output is disabled and the
display is shut down; turning the ignition from off to on awakens 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. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking-up trailer lamps.
Driving while you tow
When towing a trailer:
• Consult your local motor vehicle laws for towing a trailer.
• Do not drive faster than 70 mph (113 km/h) during the first 500 miles
(800 km) of trailer towing 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.
• Activate the tow/haul feature to eliminate excessive transmission
shifting and assist in transmission cooling. For additional information,
refer to Automatic transmission operation in the Driving chapter.
• Allow more distance for stopping with a trailer attached; anticipate
stops and brake gradually.Tires, Wheels and Loading
