WARNING: You risk death or
serious injury to yourself and others if you
do not follow the instruction highlighted
by the warning symbol. Failure to follow
the specific warnings and instructions
could result in personal injury. WARNING: Never
place front seat
mounted rear-facing child or infant seats
in front of an active passenger airbag.
On Board Diagnostics Data Link
Connector WARNING:
Do not connect
wireless plug-in devices to the data link
connector. Unauthorized third parties
could gain access to vehicle data and
impair the performance of safety related
systems. Only allow repair facilities that
follow our service and repair instructions
to connect their equipment to the data
link connector.
Your vehicle has an OBD Data Link
Connector (DLC) that is used in
conjunction with a diagnostic scan tool for
vehicle diagnostics, repairs and
reprogramming services. Installing an
aftermarket device that uses the DLC
during normal driving for purposes such as
remote insurance company monitoring,
transmission of vehicle data to other
devices or entities, or altering the
performance of the vehicle, may cause
interference with or even damage to
vehicle systems. We do not recommend
or endorse the use of aftermarket plug-in
devices unless approved by Ford. The
vehicle Warranty will not cover damage
caused by an aftermarket plug-in device. Notice to Owners of Pickup Trucks and
Utility Type Vehicles WARNING:
Utility vehicles have a
significantly higher rollover rate than
other types of vehicles.
Before you drive your vehicle, please read
this Owner ’s Manual carefully. Your vehicle
is not a passenger car. As with other
vehicles of this type, failure to operate this
vehicle correctly may result in loss of
vehicle control, vehicle rollover, personal
injury or death.
Using Your Vehicle With a Snowplow
Do not use this vehicle for
snowplowing.
Your vehicle is not equipped with a
snowplowing package.
Using Your Vehicle as an Ambulance
If your light truck is equipped with the Ford
Ambulance Preparation Package, it may
be utilized as an ambulance. Ford urges
ambulance manufacturers to follow the
recommendations of the Ford Incomplete
Vehicle Manual, Ford Truck Body Builder ’s
Layout Book and the Qualified Vehicle
Modifiers (QVM) Guidelines as well as
pertinent supplements.
For additional information, please

could gain access to vehicle data and
impair the performance of safety related
systems. Only allow repair facilities that
follow our service and repair instructions
to connect their equipment to the data

We respect your privacy and are
committed to protecting it. The
information contained in this manual was
correct at the time of publication, but as
technology rapidly changes, we
recommend that you visit the local Ford
website for the latest information.
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.
Services That We Provide
If you use our services, we collect and use
data, for example account information,
vehicle location and driving characteristics,

data through a dedicated, protected
connection. We only collect and use data
to enable your use of our services to which
you have subscribed, with your consent or
where permitted by law. For additional
information, see the terms and conditions
of the services to which you have

For additional information about our
privacy policy, refer to the local Ford

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 will 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.
