For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
•
When adding accessories, equipment,
passengers and luggage to your
vehicle, do not exceed the total weight
capacity of the vehicle or of the front
or rear axle (GVWR or GAWR as
indicated on the Safety Compliance
Certification label). Ask an authorized
dealer for specific weight information.
• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems
that are equipped with radio
transmitters, for example, two-way
radios, telephones and theft alarms.
Any such equipment installed in your
vehicle should comply with Federal
Communications Commission (FCC)
and Canadian Radio
Telecommunications Commission
(CRTC) regulations and should be
installed only by an authorized dealer.
• An authorized dealer needs to install
mobile communications systems.
Improper installation may harm the
operation of your vehicle, particularly
if the manufacturer did not design the
mobile communication system
specifically for automotive use.
• If you or an authorized Ford dealer add
any non-Ford custom electrical or
electronic accessories or components
to your vehicle, you may adversely
affect battery performance and
durability. In addition, you may also
adversely affect the performance of
other electrical systems in the vehicle. AUXILIARY SWITCHES
The auxiliary switchboard on the center
console makes aftermarket customization
easier, with four prewired switches
attached to the power distribution box for
electrical accessories.
These switches are labeled AUX 1,
AUX
2, AUX 3 and AUX 4. They will only
operate while the ignition is in the on
position, whether the engine is running or
not. It is, however, recommended that the
engine remain running to maintain a
battery charge when using the switches
for an extended duration or higher current
draws. When switched on by the operator
they provide 10 amps, 15 amps or 30 amps
of electrical battery power for a variety of
uses. The switches control relays and fuses that
are located under the hood in the auxiliary
switch pass through circuits.

There will also be one power lead for each
switch found as a blunt-cut and sealed
wire located to the right of the glove box
door and just above the passenger side
kick panel. You may need to pull down the auxiliary
cords to access them.
Refer to the Fuses chapter of your
Owner ’s Manual for information on fuse
and relay locations. See your authorized
dealer for service.
Additional pass through circuits that run
through the dash panel and under the
hood, are located in the same location.
