We will repair or replace any properly
authorized dealer-installed Ford Original
Accessory found to be defective in
factory-supplied materials or workmanship
during the warranty period, as well as any
component damaged by the defective
accessories.
We will warrant your Ford Original
Accessory through the warranty that
provides the greatest benefit:
• 24 months, unlimited mileage.
• The remainder of your new vehicle
limited warranty.
Contact an authorized dealer for details
and a copy of the warranty.
Ford Licensed Accessories are the
accessory manufacturer's designs. The
manufacturer develops and therefore
warrants Ford Licensed Accessories, and
does not design or test these accessories
to Ford Motor Company engineering
requirements. Contact an authorized Ford
dealer for the manufacturer ’s limited
warranty details, and request a copy of the
Ford Licensed Accessories product limited
warranty from the accessory manufacturer. 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 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.

For maximum vehicle performance, keep
the following information in mind when
adding accessories or equipment to your
vehicle:
• When adding accessories, equipment,

• If you or an authorized Ford dealer add
any non-Ford 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. The auxiliary switch option package
provides six switches mounted in the
overhead console. These switches operate
when the vehicle is running or from battery
power, depending on the switchable fuse
AUXF4's location in the upfitter relay box.
We recommend, 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 has a diesel
engine, use the auxiliary switches only when
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 electrical battery power for a
variety of personal or commercial uses.
Switches 1 through 4 provide 25 amps.
Switches 5 and 6 provide 40 amps.
The relay box for the auxiliary switches is
in the rear of the engine compartment,
near the back wall. See your authorized
dealer for service.
The relays are coded as shown:
