Satellite radio reception factors:To receive the satellite signal, your
vehicle has been equipped with a satellite radio antenna located on the
roof of your vehicle. The vehicle roof provides the best location for an
unobstructed, open view of the sky, a requirement of a satellite radio
system. Like AM/FM, there are several factors that can affect satellite
radio reception performance:
•Antenna Obstructions: For optimal reception performance, keep the
antenna clear of snow and ice build-up and keep luggage and other
material as far away from the antenna as possible.
•Terrain: Hills, mountains, tall buildings, bridges, tunnels, freeway
overpasses, parking garages, dense tree foliage and thunderstorms can
interfere with your reception.
•Station overload: When you pass a ground based broadcast repeating
tower, a stronger signal may overtake a weaker one and result in an
audio mute.
Unlike AM/FM audible static, you will hear an audio mute when there is
a satellite radio signal interference. Your radio display may display NO
SIGNAL to indicate the interference.
SIRIUS satellite radio service:SIRIUS Satellite Radio is a continental
U.S. based satellite radio service that broadcasts over 120 channels of
music, sports, news and entertainment coast-to-coast. A service fee is
required in order to receive SIRIUS service. Vehicles that are equipped

or delete programming including canceling, moving or adding particular

Motor Company shall not be responsible for any such programming

Satellite Radio Electronic Serial Number (ESN):This12digit
Satellite Serial Number is needed to activate, modify or track your
satellite radio account. You will need this number when communicating

THE BETTER BUSINESS BUREAU (BBB) AUTO LINE PROGRAM
(U.S. ONLY)
Your satisfaction is important to Ford Motor Company and to your dealer.
Experience has shown that our customers have been very successful in
achieving satisfaction by following the three-step procedure outlined on
the front page of the Warranty Guide. However, if your warranty concern
has not been resolved using the three-step procedure, you may be
eligible to participate in the BBB AUTO LINE program.
The BBB AUTO LINE program consists of two parts – mediation and
arbitration. Initially, the BBB will try to resolve your question or concern
through mediation. Mediation is a process through which a
representative of the BBB will contact the parties and explore options
for settlement of your claim. If mediation is not successful, customers
with eligible claims may participate in the BBB AUTO LINE arbitration
process. An arbitration hearing will be scheduled so that you can present
your case in an informal setting before an impartial person. The
arbitrator will consider the testimony provided and make a decision after
the hearing. You are not bound by the decision but may choose to accept
it. If you choose to accept the BBB AUTO LINE decision then Ford must
abide by the accepted decision as well. If the arbitrator has decided in
your favor and you accept the decision, the BBB AUTO LINE program
will contact you to ensure that Ford has complied with the decision in a
timely manner. Disputes submitted to the BBB AUTO LINE program are
usually decided within forty days after you file your claim with the BBB.
To initiate a claim with the BBB AUTO LINE, you will be asked for your
name and address, general information about your new vehicle,
information about your warranty concerns and any steps you have
already taken to try to resolve them. You will then be mailed a Customer
Claim Form that you will need to complete, provide proof of vehicle
ownership, sign and return the Customer Claim Form to the BBB. Upon
receipt, the BBB will review the claim for eligibility under the Program
Summary Guidelines.
You can get more information by calling BBB AUTO LINE at
1–800–955–5100, or writing to:
BBB AUTO LINE
4200 Wilson Boulevard, Suite 800
Arlington, Virginia 22203–1833
Note:Ford Motor Company reserves the right to change eligibility
limitations, modify procedures, or to discontinue this process at any time
without notice and without obligation.
