2008 FORD SUPER DUTY battery

The auxiliary power point is located
on the instrument panel.
On SuperCab and Crew Cab models,another power point is located
on the rear of the center console (if equipped).
Do not use the power point for operating the cigarette lighter element (if
equipped).
To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W.
To prevent the battery from being discharged, do not use the power
point longer than necessary when the engine is not running.
Always keep the power point caps closed when not being used.
Cigar lighter (if equipped)
Do not plug optional electrical accessories into the cigarette lighter
socket.
Do not hold the lighter in with your hand while it is heating, this will
damage the lighter element and socket. The lighter will be released from
its heating position when it is ready to be used.
Note:If the power point or cigar lighter socket is not working, a fuse
may have blown. Refer to theFuses and relaysin theRoadside
Emergencieschapter information on checking and replacing fuses.
Improper use of the lighter can cause damage not covered by your
warranty.

UPFITTER CONTROLS (IF EQUIPPED)
Your vehicle may be equipped with
the Upfitter option package which
will provide four switches, mounted
in the center of the instrument
panel, labeled AUX 1, AUX 2, AUX 3
and AUX 4. These switches will only
operate while the ignition is in the
3 (ON) position, whether the engine
is running or not. It is, however, recommended that the engine remain
running to maintain battery charge when using the Upfitter switches for
extended duration or higher current draws. (This is even more important
for vehicles with diesel engines since the glow plugs are also draining
battery power when the ignition key is in the 3 [ON] position.)
When switched on by the operator they provide 10 amps, 15 amps or
30 amps of electrical battery power for a variety of personal or
commercial uses.
If your vehicle is equipped with this option, there will also be a relay box
located on the driver side end of the instrument panel. See your
authorized dealer for service.

HOMELINKWIRELESS CONTROL SYSTEM
The HomeLink
Wireless Control
System, located on the driver’s visor,
provides a convenient way to
replace up to three hand-held
transmitters with a single built-in
device. This feature will learn the
radio frequency codes of most
transmitters to operate garage
doors, entry gate operators, security systems, entry door locks, and
home or office lighting.
When programming your HomeLink
Wireless Control System to
a garage door or gate, be sure that people and objects are out of
the way to prevent potential harm or damage.
Do not use the HomeLink
Wireless Control System with any garage
door opener that lacks safety stop and reverse features as required by
U.S. federal safety standards (this includes any garage door opener
model manufactured before April 1, 1982). A garage door which cannot
detect an object, signaling the door to stop and reverse, does not meet
current U.S. federal safety standards. For more information, contact
HomeLink
at:www.homelink.comor1–800–355–3515.
Retain the original transmitter for use in other vehicles as well as for
future programming procedures (i.e. new HomeLink
equipped vehicle
purchase). It is also suggested that upon the sale of the vehicle, the
programmed Homelink
buttons be erased for security purposes, refer to
Programmingin this section.
Programming
Do not program HomeLink
with the vehicle parked in the garage.
Note:Your vehicle may require the ignition switch to be turned to the
ACC position for programming and/or operation of the HomeLink
.Itis
also recommended that a new battery be placed in the hand-held
transmitter of the device being programmed to HomeLink
for quicker
training and accurate transmission of the radio-frequency signal.

Distance to empty (DTE)
Selecting this function from the
INFO MENU estimates
approximately how far you can drive
with the fuel remaining in your tank
under normal driving conditions.
Remember to turn the ignition OFF
when refueling to allow this feature to correctly detect the added fuel.
The DTE function will display LOW FUEL LEVEL and sound a chime for
one second when you have approximately 50 miles (80 km) to empty. If
you RESET this warning message, this display and chime will return
within 10 minutes.
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 500 miles (800 km). This value is not
the same as the average fuel economy display. The running average fuel
economy is reinitialized to a factory default value if the battery is
disconnected.
Average fuel economy (AFE)
Select this function to display your
average fuel economy in miles/gallon
or liters/km.
If you calculate your average fuel
economy by dividing miles traveled
by gallons of fuel used (liters of fuel
used by 100 kilometers traveled), your figure may be different than
displayed for the following reasons:
•Your vehicle was not perfectly level during fill-up
•Differences in the automatic shut-off points on the fuel pumps at
service stations
•Variations in top-off procedure from one fill-up to another
