relay FORD SUPER DUTY 2014 3.G Owners Manual

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See the Fuses
chapter.
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a tow bar with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See Load Limit (page
174). You can also find the
information in the RV & Trailer
Towing Guide, available at an
authorized dealer.

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 located in
the engine compartment. It has
high-current fuses that protect your
vehicle's main electrical systems from
overloads.
If you disconnect and reconnect the
battery, you will need to reset some
features. See Changing the 12V Battery
(page 234).

•
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). Consult your
authorized dealer for specific weight
information.
• 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
adversely affect battery performance
and durability, and may adversely
affect the performance of other
electrical systems in the vehicle. AUXILIARY SWITCHES
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:
