Your vehicle has electronic control units
that have data recording functionality and
the ability to permanently or temporarily
store data. This data could include
information on the condition and status of
your vehicle, vehicle maintenance
requirements, events and malfunctions.
The types of data that can be recorded are
described in this section. Some of the data
recorded is stored in event logs or error
logs.
Note:
Error logs are reset following a service
or repair.
Note: We may provide information in
response to requests from law enforcement,
other government authorities and third
parties acting with lawful authority or
through a legal process. Such information
could be used by them in legal proceedings.
Data recorded includes, for example:
• Operating states of system
components, for example, fuel level,
tire pressure and battery charge level.
• Vehicle and component status, for
example, wheel speed, deceleration,
lateral acceleration and seatbelt
status.
• Events or errors in essential systems,
for example, headlamps and brakes.
• System responses to driving situations,
for example, airbag deployment and
stability control.
• Environmental conditions, for example,
temperature.
Some of this data, when used in
combination with other information, for
example, an accident report, damage to a
vehicle or eyewitness statements, could
be associated with a specific person. Service Data
Service data recorders in your vehicle are
capable of collecting and storing
diagnostic information about your vehicle.
This potentially includes information about
the performance or status of various
systems and modules in the vehicle, such
as engine, throttle, steering or brake
systems. In order to properly diagnose and
service your vehicle, Ford Motor Company
(Ford of Canada in Canada), and service
and repair facilities may access or share
among them vehicle diagnostic
information received through a direct
connection to your vehicle when
diagnosing or servicing your vehicle.
Additionally, Ford Motor Company (Ford
of Canada, in Canada) may, where
permitted by law, use vehicle diagnostic
information for vehicle improvement or
with other information we may have about
you, for example, your contact information,
to offer you products or services that may
interest you. Data may be provided to our
service providers such as part suppliers
that may help diagnose malfunctions, and
who are similarly obligated to protect data.
We retain this data only as long as
necessary to perform these functions or to
comply with law. We may provide
information where required in response to
official requests to law enforcement or
other government authorities or third
parties acting with lawful authority or court
order, and such information may be used
in legal proceedings. For U.S. only (if
equipped), if you choose to use connected
apps and services, you consent that certain
diagnostic information may also be
accessed electronically by Ford Motor
Company and Ford authorized service
facilities, and that the diagnostic
information may be used to provide
services to you, personalizing your
experience, troubleshoot, and to improve
products and services and offer you
products and services that may interest

you, where permitted by law. For Canada
only, for more information, please review
the Ford of Canada privacy policy at
www.ford.ca, including our U.S. data
storage and use of service providers in
other jurisdictions who may be subject to
legal requirements in Canada, the United
States and other countries applicable to
them, for example, lawful requirements to
disclose personal information to
governmental authorities in those
countries.
Event Data
This vehicle is equipped with an event data
recorder. The main purpose of an event
data recorder is to record, in certain crash
or near crash-like situations, such as an
airbag deployment or hitting a road
obstacle; this data assist in understanding
how a vehicle
’s systems performed. The
event data recorder is designed to record
data related to vehicle dynamics and
safety systems for a short period of time,
typically 30 seconds or less.
The event data recorder in this vehicle is
designed to record such data as:
• How various systems in your vehicle
were operating.
• Whether or not the driver and
passenger seatbelts were
buckled/fastened.
• How far (if at all) the driver was
depressing the accelerator and/or the
brake pedal.
• How fast the vehicle was traveling.
• Where the driver was positioning the
steering wheel.
This data can help provide a better
understanding of the circumstances in
which crashes and injuries occur. Note:
Event data recorder data is recorded
by your vehicle only if a non-trivial crash
situation occurs; no data is recorded by the
event data recorder under normal driving
conditions and no personal data or
information (e.g., name, gender, age, and
crash location) is recorded. However, other
parties, such as law enforcement, could
combine the event data recorder data with
the type of personally identifying data
routinely acquired during a crash
investigation.
To read data recorded by an event data
recorder, special equipment is required,
and access to the vehicle or the event data
recorder is needed. In addition to the
vehicle manufacturer, other parties, such
as law enforcement, that have such special
equipment, can read the information if they
have access to the vehicle or the event
data recorder.
Comfort, Convenience and
Entertainment Data
Your vehicle has electronic control units
that have the ability to store data based
on your personalized settings. The data is
stored locally in the vehicle or on devices
that you connect to it, for example, a USB
drive or digital music player. You can delete
some of this data and also choose whether
to share it through the services to which
you subscribe. See Settings (page 543).
Comfort and Convenience Data
Data recorded includes, for example:
• Seat and steering wheel position.
• Climate control settings.
• Radio presets.

REPLACEMENT PARTS
RECOMMENDATION
We have built your vehicle to the highest
standards using quality parts. We
recommend that you demand the use of
genuine Ford and Motorcraft parts

these parts deliver the intended level of
protection as a whole system. A great way
to know for sure you are getting this level
of protection is to use genuine Ford
replacement collision parts.

If the booster seat slides on the vehicle
seat upon which it is being used, placing a
rubberized mesh sold as shelf or carpet
liner under the booster seat may improve
this condition. Do not introduce any item
thicker than this under the booster seat.
Check with the booster seat
manufacturer's instructions.
CHILD RESTRAINT
POSITIONING
WARNING: Do not place a
rearward facing child restraint in front of
an active airbag. Failure to follow this
instruction could result in personal injury
or death. WARNING:
Properly secure
children 12 years old and under in a rear
seating position whenever possible. If
you are unable to properly secure all
children in a rear seating position,
properly secure the largest child on the
front seat. If you must use a forward
facing child restraint on the front seat,
move the seat as far back as possible.
Failure to follow these instructions could
result in personal injury or death. WARNING: Always carefully follow
the instructions and warnings provided
by the manufacturer of any child
restraint to determine if the restraint
device is appropriate for your child's size,
height, weight, or age. Follow the child
restraint manufacturer's instructions and
warnings provided for installation and
use in conjunction with the instructions
and warnings provided by your vehicle
manufacturer. A safety seat that is
improperly installed or utilized, is
inappropriate for your child's height, age,
or weight or does not properly fit the
child may increase the risk of serious
injury or death. WARNING:
Do not allow a
passenger to hold a child on their lap
when your vehicle is moving. Failure to
follow this instruction could result in
personal injury or death in the event of a
sudden stop or crash. WARNING:
Do not use pillows,
books or towels to boost your child's
height. Failure to follow this instruction
could result in personal injury or death.
