If you use oil and fluids that do not meet
the defined specification and viscosity
grade, this may lead to:
•
Component damage which is not
covered by the vehicle warranty.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Degraded brake performance.
We recommend Motorcraft® motor oil for
your vehicle. If Motorcraft® oil is not
available, use motor oils of the
recommended viscosity grade that meet
API SN requirements and display the API
Certification Mark for gasoline engines. Do
not use oil labeled with API SN service
category unless the label also displays the
API certification mark. An oil that displays this symbol conforms
to current engine, emission system and
fuel economy performance standards of
ILSAC.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by your vehicle warranty.
Note:
Ford recommends using DOT 4 Low
Viscosity (LV) High Performance Brake Fluid
or equivalent meeting WSS-M6C65-A2. Use
of any fluid other than the recommended
fluid may cause degraded brake
performance and not meet the Ford
performance standards. Keep brake fluid
clean and dry. Contamination with dirt,
water, petroleum products or other
materials may result in brake system
damage and possible failure.
Note: Automatic transmissions that require
MERCON® LV transmission fluid should
only use MERCON® LV transmission fluid.
The use of any other fluid may cause
transmission damage.
Alternative Engine Oil for
Extremely Cold Climates
To improve engine cold start performance,
we recommend that you use the following
alternative engine oil in extremely cold
climates, where the ambient temperature
reaches -22.0°F (-30°C) or below.

If you do not cancel the call, and SYNC
makes a successful call, a pre-recorded
message plays for the 911 operator, and
then the occupant(s) in your vehicle is 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.
911 Assist May Not Work If
•
Your cellular phone or 911 Assist
hardware sustains damage in a crash.
• The vehicle's battery or the SYNC
system has no power.
• The phone(s) thrown from your vehicle
are the ones paired and connected to
the system.
911 Assist Privacy Notice
When you turn on 911 Assist, 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 911 Assist may also be capable
of electronically or verbally disclosing to
911 operators your vehicle location or other
details about your vehicle or crash to assist
911 operators to provide the most
appropriate emergency services. If you do
not want to disclose this information, do
not turn the feature on.
SYNC™ APPLINK ™
SYNC Mobile Apps
Note: You must pair and connect your
smartphone to SYNC to access AppLink.
Note: iPhone users need to connect the
phone to the USB port in order to start the
application. Note:
The AppLink feature is not available
if your vehicle is equipped with the MyFord
Touch system.
Note: Depending on your display type, you
can access AppLink from the media menu,
the phone menu, or by using voice
commands. Once an app is running through
AppLink, you can control main features of
the app through voice commands and
steering wheel controls.

For important information about airbag
deployment and the fuel pump shut-off
please see the Supplementary Restrains
and Roadside Emergencies sections of
your owner manual.
To switch 911 Assist on and off please view
the settings information. See Settings
(page 415).
To make sure that 911 Assist works
correctly:
• SYNC must be 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.
• A connected Bluetooth-enabled phone
must have adequate network coverage,
battery power and signal strength.
• The vehicle must have battery power
and be located in the U.S., Canada or
in a territory in which 911 is the
emergency number.
In the Event of a Crash
Not all crashes will deploy an airbag or
activate the fuel pump shut-off (the
triggers for 911 Assist). 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 a short window of time
(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, and
then the occupant(s) in your vehicle is 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.
911 Assist May Not Work If
• Your cellular phone or 911 Assist
hardware sustains damage in a crash.
• The vehicle's battery or the SYNC
system has no power.
• The phone(s) thrown from your vehicle
are the ones paired and connected to
the system.
