battery FORD F-450 2021 Workshop Manual

Engine
•
Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast
idle with the climate controls set to
defrost until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Disconnecting Your 12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting.
Note: It is necessary to reset memory
features if you disconnect the battery
cables. Brakes
•
Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.

If a crash deploys an airbag, excluding knee
airbags and rear inflatable seatbelts, or
activates the fuel pump shut-off, your
vehicle may be able to contact emergency
services by dialing 911 through a paired and
connected Bluetooth®-enabled phone.
See
Supplementary Restraints System
(page 45). Important information about
airbag deployment is in this chapter.
See
Roadside Emergencies (page 325).
Important information about the fuel pump
shut-off is in this chapter.
Setting 911 Assist On or Off
Press the Settings button then select: Action and Description
Menu
Item
Select the desired option, on
or off.
911 Assist
To make sure that 911 Assist works
properly:
• SYNC must be powered and working
properly at the time of the incident and
throughout feature activation and use.
• The 911 Assist feature must be set on
before the incident.
• You must pair and connect a
Bluetooth®
enabled and compatible
cell phone to SYNC.
• A connected
Bluetooth® enabled
phone must have the ability to make
and maintain an outgoing call at the
time of the incident.
• A connected
Bluetooth® enabled
phone must have adequate network
coverage, battery power and signal
strength.
• The vehicle must have battery power
and be located in the U.S., Canada or
in a territory in which 911 is the
emergency number. In the Event of a Crash
Not all crashes deploy an airbag or activate
the fuel pump shut-off (the triggers for 911
Assist). If a connected cell phone sustains
damage or loses its connection to SYNC
during a crash, SYNC searches for and tries
to connect to a previously paired cell
phone; SYNC then attempts to call the
emergency services.
Before making the call:
•
SYNC provides a short window of time
(about 10 seconds) to cancel the call.
If you fail to cancel the call, SYNC
attempts to dial 911.
• SYNC says the following, or a similar
message: "SYNC will attempt to call
911, to cancel the call, press Cancel on
your screen or press and hold the
phone button on your steering wheel".
If you do not cancel the call, and SYNC
makes a successful call, a pre-recorded
message plays for the 911 operator, and
then the occupant(s) in your vehicle are
able to talk with the operator. Be prepared
to provide your name, phone number and
location immediately, because not all 911
systems are capable of receiving this
information electronically.
911 Assist May Not Work If
• Your cellular phone or 911 Assist
hardware sustains damage in a crash.
• The vehicle's battery or the SYNC
system has no power.
• The phone(s) thrown from your vehicle
are the ones paired and connected to
the system.

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.

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:
