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.
• Any non-Ford custom 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
