FUSE SPECIFICATION CHART
Power Distribution Box
WARNINGS
Always disconnect the battery before
servicing high current fuses.
To reduce risk of electrical shock,
always replace the cover to the
power distribution box before
reconnecting the battery or refilling fluid
reservoirs. The power distribution box is in the engine
compartment. It has high-current fuses
that protect your vehicle's main electrical
systems from overloads.
If the battery has been disconnected and
reconnected, some features will need to
be reset. See Changing the 12V Battery
(page 354).

State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle
’s paint finish, wiper blades or
washer system.
DRAINING THE FUEL FILTER
WATER TRAP - 6.7L DIESEL WARNING
Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized
waste disposal facility. Your vehicle has a diesel fuel conditioner
module. The module is mounted between
the outboard side of the fuel tank and the
frame rail.
Note:
The module is at the front of the fuel
tank or at the front of the aft-axle fuel tank
on some models. You should drain water from the
module assembly whenever the
warning light illuminates or a
message appears in the information
display advising you to drain the water
separator. This occurs when approximately
6.76 fl oz (200 ml) of water accumulates
in the module. If you allow the water level
to exceed this level, the water may pass
through to the engine and may cause fuel
injection equipment damage.

•
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. 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:
