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 App
Requirements (page 649).
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, the
SYNC module serial number, odometer,
enabled apps, 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 Performing a Master
Reset (page 657).
System data cannot be accessed without
special equipment and access to your
vehicle's module.
For additional information about our
privacy policy, refer to the local Ford
website.
Note: To find out if your vehicle has
connectivity technology, visit
www .For dC onne c t e d . c om .
EMERGENCY CALL SYSTEM
DATA
(IF EQUIPPED)
When the emergency call system is active,
it may disclose to emergency services that
your vehicle has been in a crash involving
the deployment of an airbag or activation
of the fuel pump shut-off. Certain versions
or updates to the emergency call system
may also be capable of electronically or
verbally disclosing to emergency services
operators your vehicle location or other
details about your vehicle or crash to assist
emergency services operators to provide
the most appropriate emergency services.
If you do not want to disclose this
information, do not activate the emergency
call system.
Note: You cannot deactivate emergency
call systems that are required by law.

WHAT IS 911 ASSIST
911 Assist is a SYNC system feature that
can call for help.
For more information, visit
www
. o wner .f or d . c om .
HOW DOES 911 ASSIST WORK
If a crash deploys an airbag, excluding knee
airbags and rear inflatable seatbelts, or
activates the fuel pump shut-off, your
vehicle may be able to contact emergency
services by dialing 911 through a paired and
connected Bluetooth®-enabled phone.
Not all crashes will deploy an airbag or
activate the fuel pump shut-off. If a
connected cell phone sustains damage or
loses its connection to SYNC during a
crash, SYNC will search for and try to
connect to a previously paired cell phone.
SYNC will then attempt to call the
emergency services.
Before making the call:
• SYNC provides about 10 seconds to
cancel the call. If you fail to cancel the
call, SYNC attempts to dial 911.
• SYNC says the following, or a similar
message: "SYNC will attempt to call
911, to cancel the call, press Cancel on
your screen or press and hold the
phone button on your steering wheel."
If you do not cancel the call and SYNC
makes a successful call a pre-recorded
message plays for the 911 operator. The
occupants in your vehicle are able to talk
with the operator. Be prepared to provide
your name, phone number and location
immediately because not all 911 systems
are capable of receiving this information
electronically.
During an emergency call the system
transmits vehicle data to the emergency
service. EMERGENCY CALL
REQUIREMENTS WARNING:
Do not wait for 911
Assist to make an emergency call if you
can do it yourself. Dial emergency
services immediately to avoid delayed
response time which could increase the
risk of serious injury or death after a
crash. If you do not hear 911 Assist within
five seconds of the crash, the system or
phone may be damaged or
non-functional. WARNING:
Always place your
phone in a secure location in your vehicle
so it does not become a projectile or get
damaged in a crash. Failure to do so may
cause serious injury to someone or
damage the phone which could prevent
911 Assist from working properly. WARNING:
Unless the 911 Assist
setting is set on before a crash, the
system will not dial for help which could
delay response time, potentially
increasing the risk of serious injury or
death after a crash.
• SYNC is powered and working properly
at the time of the incident and
throughout feature activation and use.
• The 911 Assist feature must be set on
before the incident.
• You must pair and connect a
Bluetooth®
enabled and compatible
cell phone to SYNC.
• A connected
Bluetooth® enabled
phone must have the ability to make
and maintain an outgoing call at the
time of the incident.

WHAT IS A HYBRID ELECTRIC
VEHICLE
A hybrid vehicle has an electric motor and
a high voltage battery combined with a
gasoline engine.
HOW DOES A HYBRID
ELECTRIC VEHICLE WORK
The hybrid vehicle combines electric and
gasoline propulsion to provide optimal
performance and improved efficiency.
HYBRID ELECTRIC VEHICLE
DRIVING CHARACTERISTICS
The gasoline engine starts and stops to
provide power when required and to save
fuel when not needed. When coasting at
low speeds, coming to a stop or standing,
the gas engine normally shuts down and
your vehicle operates in electric-only
mode.
Conditions that may cause the gasoline
engine to start or remain running include:
•
Considerable vehicle acceleration.
• Driving uphill.
• The high voltage battery charge level
is low.
• Heating or cooling the vehicle interior
in high or low outside temperatures.
• The gasoline engine is below normal
operating temperature.
• Towing a trailer.
• Certain selectable drive modes could
cause the engine to run. See Selecting
a Drive Mode (page 373). Use of the
paddle shifters while in drive (D) could
cause the engine to run. Your hybrid vehicle also comes with
standard hydraulic braking and
regenerative braking. Regenerative braking
is performed by your transmission and
captures brake energy and stores it in the
high voltage battery.
You could also notice that your engine
continues to run instead of shutting off
during extended downhill driving. The
engine stays on during this engine braking
but is not using any fuel.
You could also hear a slight whine or
whistle when operating your vehicle. This
is the normal operation of the electric
motor in the hybrid system.
HYBRID ELECTRIC VEHICLE
INDICATORS
When you start your vehicle, a
green READY indicator light
appears in the instrument cluster
letting you know that your vehicle is ready
for driving.
The engine may not start because your
vehicle has a silent key start feature. This
fuel saving feature allows your vehicle to
be ready to drive without requiring the gas
engine to be running.
The indicator remains on when your vehicle
is on, whether the engine is running or not,
to indicate your vehicle is capable of
movement using the electric motor, gas
engine or both.
Typically, the engine does not start unless
the vehicle is cold, a climate control
change is requested or you press the
accelerator pedal.

FUEL QUALITY
SELECTING THE CORRECT FUEL -
FLEX FUEL – ETHANOL
Flex fuel vehicles have one of the following
identifiers:
•
Yellow fuel filler cap.
• Yellow bezel around the fuel filler inlet.
• Yellow fuel filler housing.
• Yellow E85 label on the fuel tank filler
door. Your vehicle operates on regular unleaded
gasoline with a minimum pump (R+M)/2
octane rating of 87 or regular unleaded
gasoline blended with a maximum of 85%
ethanol (E85).
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. The use of these fuels
could result in engine damage that will not
be covered by the vehicle Warranty.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing a Trailer
(page 428). Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance.
For additional information, visit
www
.t op tier g a s. c om .
Note: Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuels containing more than 85%
ethanol or E100 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl, which is a
manganese-based fuel additive, will impair
engine performance and affect the
emission control system.

WARNING: Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See
Locating
the Fuel Filler Funnel (page 260).
Note: Do not use aftermarket funnels as
they may not work with the capless fuel
system and can damage it.
When refueling the vehicle fuel tank from
a fuel container, do the following:
1. Fully open the fuel filler door. 2.
Fully insert the fuel filler funnel into the
fuel filler inlet.
3. Add fuel to your vehicle from the fuel container.
4. Remove the fuel filler funnel.
5. Fully close the fuel filler door.
6. Clean the fuel filler funnel and place it back in your vehicle or correctly dispose
of it. Note:
If your vehicle runs out of fuel add a
minimum of
1.3 gal (5 L) of fuel to restart
the engine.
Note: You may need to switch the ignition
from off to on several times after refueling
to allow the fuel system to pump the fuel
from the tank to the engine. When
restarting, cranking time takes a few
seconds longer than normal.
Note: Extra funnels can be purchased from
an authorized dealer if you choose to
dispose of the funnel.
