2019 FORD F-250 auxiliary battery

12 V DC Power Point
WARNING: Do not plug optional
electrical accessories into the cigar
lighter socket. Incorrect use of the cigar
lighter can cause damage not covered
by the vehicle warranty, and can result
in fire or serious injury.
Note: When you switch the ignition on, you
can use the socket to power
12 V appliances
with a maximum current rating of 20 A20
amps.
Note: Do not plug in any device that
supplies power to the vehicle through the
power points, this may result in damage to
vehicle systems.
Note: Do not hang any accessory from the
accessory plug.
Note: Do not use the power point over the
vehicle capacity of 12 V DC 240 W or a fuse
may blow.
Note: Always keep the power point caps
closed when not in use.
Do not insert objects other than an
accessory plug into the power point. This
damages the power point and may blow
the fuse.
Run the vehicle for full capacity use of the
power point.
To prevent the battery from running out of
charge:
• Do not use the power point longer than
necessary when the engine is off.
• Do not leave devices plugged in
overnight or when you park your vehicle
for extended periods. 110 V 400 Watt AC Power Point
(If
Equipped) WARNING: Do not keep electrical
devices plugged in the power point
whenever the device is not in use. Do not
use any extension cord with the 110 volt
AC power point, since it will defeat the
safety protection design. Doing so may
cause the power point to overload due
to powering multiple devices that can
reach beyond the 400 watt load limit
and could result in fire or serious injury.
Note: This feature works only when you
have the ignition switched on.
Note: This feature has a maximum output
of 400 watts when the vehicle is in park (P).
Note: While in drive (D), the maximum
outlet output is 300 watts.
Note: When powering electric devices that
require more than 10 watts in vehicles
equipped with keyless start, the engine must
remain running. If the engine is turned off or
you switch the ignition to accessory mode,
plugged in devices will not be charged.
You can use the power point for electric
devices that require up to 400 watts. It is
on the instrument panel, and the rear of
the center console. 168

AUXILIARY SWITCHES (IF
EQUIPPED)
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
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 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. 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:
