• The Federal Communications
Commission (FCC) and Canadian
Radio Telecommunications
Commission (CRTC) regulate the use
of mobile communications systems —
such as two-way radios, telephones
and theft alarms — that are equipped
with radio transmitters. Any such
equipment installed in your vehicle
should comply with Federal
Communications Commission (FCC)
and Canadian Radio
Telecommunications Commission
(CRTC) regulations and installed only
by a qualified service technician.
• 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.
• Any non-Ford custom electrical or
electronic accessories or components
that are added to the vehicle by the
authorized dealer or the owner, may

affect the performance of other
electrical systems in the vehicle.
AUXILIARY SWITCHES
E163431
The auxiliary switch option package
provides four switches, mounted in the
center of the instrument panel. These
switches will operate only while the ignition
is in the on position, whether the engine is
running or not. It is recommended,
however, that the engine remain running
to maintain battery charge when using the
auxiliary switches for extended periods of
time or higher current draws.
Note: When your vehicle is equipped with
a diesel engine, use the auxiliary switches
only while the engine is running. The glow
plugs also drain battery power when the
ignition key is in the on position. Using the
auxiliary switches, even for limited amounts
of time, can cause your battery to drain
quickly and prevent your vehicle from
restarting.
When switched on, the auxiliary switches
provide 8 amps, 12 amps or 20 amps of
electrical battery power for a variety of
personal or commercial uses.
The relay box for the auxiliary switches is
located on the end of the left side of the
instrument panel. See your authorized
dealer for service.
The relays are coded as shown below:
