Vehicles With SYNC
Mobile Device Data
If you connect a mobile device to your
vehicle, you can display data from your
device on the touchscreen for example,
music and album art. You can share your
vehicle data with mobile apps on your
device through the system. See
Apps
(page 420).
The mobile apps function operates by your
connected device sending data to us in the
United States. The data is encrypted and
includes, for example, the vehicle
identification number of your vehicle,
odometer, SYNC module number,
anonymous usage statistics and debugging
information. We retain it only as long as
necessary to provide the service, to
troubleshoot, for continuous improvement
and to offer you products and services that
may be of interest to you according to your
preferences and where allowed by law. If you connect a cell phone to the system,
the system creates a profile that links to
that cell phone. The cell phone profile
enables more mobile features and efficient
operation. The profile contains, for
example, data from your phonebook, read
and unread text messages and call history,
including history of calls when your cell
phone was not connected to the system.
If you connect a media device, the system
creates and retains a media device index
of supported media content. The system
also records a short diagnostic log of
approximately 10 minutes of all recent
system activity.
The cell phone profile, media device index
and diagnostic log remain in your vehicle
unless you delete them and are generally
accessible only in your vehicle when you
connect your cell phone or media device.
If you no longer plan to use the system or
your vehicle, we recommend you use the
master reset function to erase the stored
information. See
Settings (page 423).
System data cannot be accessed without
special equipment and access to your
vehicle's module.

PRINCIPLE OF OPERATION
WARNING: Airbags do not inflate
slowly or gently, and the risk of injury
from a deploying airbag is the greatest
close to the trim covering the airbag
module. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
Even with advanced
restraints systems, properly restrain
children 12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or
death. WARNING:
Do not place your arms
on the airbag cover or through the
steering wheel. Failure to follow this
instruction could result in personal injury. WARNING:
Keep the areas in front
of the airbags free from obstruction. Do
not affix anything to or over the airbag
covers. Objects could become projectiles
during airbag deployment or in a sudden
stop. Failure to follow this instruction
could result in personal injury or death. WARNING: Airbags can kill or injure
a child in a child restraint. Never place a
rear-facing child restraint in front of an
active airbag. If you must use a
forward-facing child restraint in the front
seat, move the seat upon which the child
restraint is installed all the way back. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
Several airbag system
components get hot after inflation. To
reduce the risk of injury, do not touch
them after inflation. WARNING:
If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The airbags are a supplemental restraint
system and are designed to work with the
seatbelts to help protect the driver and
right front passenger from certain upper
body injuries. Airbags do not inflate slowly;
there is a risk of injury from a deploying
airbag.
Note: You will hear a loud bang and see a
cloud of harmless powdery residue if an
airbag deploys. This is normal.
The airbags inflate and deflate rapidly
upon activation. After airbag deployment,
it is normal to notice a smoke-like, powdery
residue or smell the burnt propellant. This
may consist of cornstarch, talcum powder
(to lubricate the bag) or sodium
compounds (for example, baking soda)
that result from the combustion process
that inflates the airbag. Small amounts of
sodium hydroxide may be present which
may irritate the skin and eyes, but none of
the residue is toxic.

•
Wait at least two minutes and verify
that the airbag readiness light is no
longer illuminated.
• If the airbag readiness light remains
illuminated, this may or may not be a
problem due to the front passenger
sensing system.
Do not attempt to repair or service the
system. Take your vehicle immediately to
an authorized dealer.
If it is necessary to modify an advanced
front airbag system to accommodate a
person with disabilities, contact the Ford
Customer Relationship Center. See
Getting the Services You Need (page
238).
SIDE AIRBAGS WARNING:
Do not place objects
or mount equipment on or near the
airbag cover, on the side of the front or
rear seatbacks, or in areas that may
come into contact with a deploying
airbag. Failure to follow these
instructions may increase the risk of
personal injury in the event of a crash. WARNING:
Do not use accessory
seat covers. The use of accessory seat
covers may prevent the deployment of
the side airbags and increase the risk of
injury in an accident. WARNING:
Do not lean your head
on the door. The side airbag could injure
you as it deploys from the side of the
seatback. WARNING:
Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The side airbags are on the outermost side
of the seat backrests of the front seats. In
certain sideways crashes, the side airbags
will be inflated. The airbag was designed
to inflate between the door panel and
occupant to further enhance the protection
provided occupants in side impact crashes.

WARNING: Do not attempt to
service, repair, or modify the
supplementary restraint system or
associated components. Failure to
follow this instruction could result in
personal injury or death. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
To reduce risk of injury,
do not obstruct or place objects in the
deployment path of the airbag. WARNING:
If a supplementary
restraint system component has
deployed, it will not function again. Have
the system and associated components
inspected as soon as possible. Failure to
follow this instruction could result in
personal injury or death.
The Safety Canopy deploys during
significant side crashes or when a certain
likelihood of a rollover event is detected
by the rollover sensor. The Safety Canopy
is mounted to the roof side rail sheet metal,
behind the headliner, above each row of
seats. In certain sideways crashes or
rollover events, the Safety Canopy will be
activated, regardless of which seats are
occupied. The Safety Canopy is designed
to inflate between the side window area
and occupants to further enhance
protection provided in side impact crashes
and rollover events. The system consists of the following:
•
Safety Canopy curtain airbags above
the trim panels over the front and rear
side windows identified by a label or
wording on the headliner or roof-pillar
trim.
• A flexible headliner which opens above
the side doors to allow air curtain
deployment · Crash sensors and monitoring
system with a readiness
indicator. See
Crash Sensors
and Airbag Indicator (page 56).
Properly restrain children 12 years old and
under in the rear seats. The Safety Canopy
will not interfere with children restrained
using a properly installed child or booster
seat because it is designed to inflate
downward from the headliner above the
doors along the side window opening.
The design and development of the Safety
Canopy included recommended testing
procedures that were developed by a
group of automotive safety experts known
as the Side Airbag Technical Working
Group. These recommended testing
procedures help reduce the risk of injuries
related to the deployment of side airbags
(including the Safety Canopy).

CRASH SENSORS AND
AIRBAG INDICATOR
WARNING: Modifying or adding
equipment to the front end of your
vehicle (including hood, bumper system,
frame, front end body structure, tow
hooks and hood pins) may affect the
performance of the airbag system,
increasing the risk of injury. Do not
modify or add equipment to the front
end of your vehicle.
Your vehicle has a collection of crash and
occupant sensors which provide
information to the restraints control
module. The restraints control module
deploys (activates) the front seatbelt
pretensioners, driver airbag, passenger
airbag, knee airbag(s), seat mounted side
airbags and Safety Canopy airbags. Based
on the type of crash, the restraints control
module will deploy the appropriate safety
devices.
The restraints control module also
monitors the readiness of the above safety
devices plus the crash and occupant
sensors. The readiness of the safety
system is indicated by a warning indicator
light in the instrument cluster or by a
backup tone if the warning light is not
working. 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 not
illuminate immediately after you
switch the ignition on. •
The readiness light either flashes or
stays lit.
• You will hear a series of five beeps. The
tone pattern repeats periodically until
the problem, the light or both are
repaired.
If any of these things happen, even
intermittently, have the supplemental
restraint system serviced at an authorized
dealer immediately. Unless serviced, the
system may not function properly in the
event of a crash.
The seatbelt pretensioners and the front
airbag supplemental restraint system are
designed to activate when the vehicle
sustains frontal deceleration sufficient to
cause the restraints control module to
deploy a safety device.
The fact that the seatbelt pretensioners
or front airbags did not activate for both
front seat occupants in a crash does not
mean that something is wrong with the
system. Rather, it means the restraints
control module determined the accident
conditions (crash severity, belt usage)
were not appropriate to activate these
safety devices.
• The design of the front airbags is to
activate only in frontal and near-frontal
crashes (not rollovers, side impacts or
rear impacts unless the crash causes
sufficient frontal deceleration).
• The design of the seatbelt
pretensioners is to activate in frontal,
near-frontal, side crashes and rollovers.
