FORD 2011 Edge v.2 - Manual (Page 365)

• Mobile communications systems may harm the operation of your
vehicle, particularly if they are not properly designed for automotive
use.
• To avoid interference with other vehicle functions, such as anti-lock
braking systems, amateur radio users who install radios and antennas
onto their vehicle should not locate the Amateur Radio Antennas in
the area of the driver’s side hood.
To ensure proper operation of the battery management system (BMS),
any electrical devices that are added to the vehicle should not have their
ground connection made directly at the negative battery post. A
connection at the negative battery post can cause inaccurate
measurements of the battery condition and potential incorrect system
operation.
• Any non-Ford electrical or electronic accessories or components that
are added to the vehicle by the authorized dealer or the owner may
adversely affect battery performance and durability and may also
adversely affect the performance of other electrical systems in the
vehicle.
