To access this information, special equipment must be directly
connected to the recording modules. Ford Motor Company and
Ford of Canada do not access event data recorder information
without obtaining consent, unless pursuant to court order or
where required by law enforcement, other government authorities
or other third parties acting with lawful authority. Other parties
may seek to access the information independently of Ford Motor
Company and Ford of Canada. Please note that once 911 Assist
(if equipped) is enabled (set ON), 911 Assist may, through any
paired and connected cell phone, disclose to emergency services
that the vehicle has been in a crash involving the deployment of
an airbag or, in certain vehicles, the 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
the vehicle location, and/or other details about the 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 activate the feature. See your SYNC

Cell phone use
The use of Mobile Communications Equipment has become increasingly
important in the conduct of business and personal affairs. However,
drivers must not compromise their own or others’ safety when using
such equipment. Mobile Communications can enhance personal safety
and security when appropriately used, particularly in emergency
situations. Safety must be paramount when using mobile communications
equipment to avoid negating these benefits.
Mobile Communication Equipment includes, but is not limited to cellular
phones, pagers, portable email devices, in-vehicle communications
systems, telematics devices and portable two-way radios.

Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/gallon or
liters/100 km.
If you calculate your average fuel
economy by dividing gallons of fuel
used by 100 miles traveled
(kilometers traveled by liters used),
your figure may be different than displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
•Rounding of the displayed values to the nearest 0.1 gallon (liter)
1. Drive the vehicle at least 5 miles (8 km) with the speed control
system engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET control (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
Instantaneous fuel economy
Select this function from the INFO
menu to display your instantaneous
fuel economy. This will display your
fuel economy as a bar graph ranging
from
poor economy to
excellent economy.
Your vehicle must be moving to
calculate instantaneous fuel
economy. When your vehicle is not moving, this function shows
one
or no bars illuminated. Instantaneous fuel economy cannot be reset.
