2021 FORD F-450 key battery

Follow these guidelines if you have a need
for recreational towing, such as towing
your vehicle behind a motorhome. We have
designed these guidelines to prevent
damage to your transmission.
Two-wheel Drive Vehicles
Do not tow your vehicle with any wheels
on the ground, as vehicle or transmission
damage may occur. You must tow your
vehicle with all four (4) wheels off the
ground, such as when using a car-hauling
trailer.
Four-wheel Drive Vehicles
If towing your vehicle with wheels off the
ground it must be all four wheels, such as
when using a car-hauling trailer.
To tow a four-wheel drive vehicle with all
wheels on the ground, place the transfer
case in its neutral position and engage the
four-wheel-down towing feature.
Perform the steps in the following section
after positioning your vehicle behind the
tow vehicle and properly securing them
together.
Note:
Make sure you properly secure your
vehicle to the tow vehicle.
Towing With All Four Wheels On The
Ground
1. Put the ignition in the on position, but do not start the engine.
2. Press and hold the brake pedal.
3. Rotate the four-wheel drive control to 2H.
4. Shift into neutral (N).
5. Using the instrument cluster display controls on the steering wheel, select
Settings
.
6. Select
Advanced Settings.
7. Select
Vehicle.
8. Select
Neutral Tow. 9. Press and hold the
OK button until a
confirmation message appears in the
information display.
Note: You may hear an audible noise as the
transfer case shifts into its neutral position.
10. If you do not see a message in the display, you must perform the
procedure again from the beginning.
11. Leave the transmission in neutral (N)
and turn the ignition off.
12. If your vehicle has an ignition key, you
must leave the key in the ignition
while towing.
Note: To lock and unlock your vehicle, use
the keyless entry keypad or extra set of keys.
13. If your vehicle has intelligent access, switch the vehicle into accessory
mode. See
Starting and Stopping
the Engine (page 174).
Note: You do not need to leave your keys
in the vehicle. You can lock and unlock your
vehicle as you normally do.
14. Release the brake pedal. WARNING:
Do not disconnect the
battery during recreational towing. It
prevents the transfer case from shifting
properly and may cause the vehicle to
roll, even if the transmission is in park
(P). WARNING:
Shifting the transfer
case to its neutral position for
recreational towing may cause the
vehicle to roll, even if the transmission is
in park (P). It may injure the driver and
others. Make sure you press the foot
brake and the vehicle is in a secure, safe
position when you shift to neutral (N).
Note: Failing to put the transfer case in its
neutral position while towing with all four
wheels on the ground will damage vehicle
components.

HAZARD FLASHERS
Note:
The hazard flashers operate when
the ignition is in any position, or if the key is
not in the ignition. If used when the vehicle
is not running, the battery loses charge. As
a result, there may be insufficient power to
restart your vehicle. The flasher control is on the
instrument panel. Use your
hazard flashers when your
vehicle is creating a safety hazard for other
motorists.
• Press the flasher control and all front
and rear direction indicators flash.
• Press the button again to switch them
off. FUEL SHUTOFF WARNING: If your vehicle has been
involved in a crash, have the fuel system
checked. Failure to follow this instruction
could result in fire, personal injury or
death.
Note: When you try to restart your vehicle
after a fuel shutoff, the vehicle makes sure
that various systems are safe to restart.
Once the vehicle determines the systems
are safe, then the vehicle allows you to
restart.
Note: In the event that your vehicle does
not restart after your third attempt, contact
a qualified technician.
The fuel pump shutoff stops the flow of
fuel to the engine in the event of a
moderate to severe crash. Not every
impact causes a shutoff.
Should your vehicle shut off after a crash,
you may restart your vehicle.
If your vehicle has a key system:
1. Switch off the ignition.
2. Switch to start position.
3. Switch off the ignition.
4. Switch on the ignition to re-enable the
fuel pump.
5. If the vehicle does not start, repeat steps 1 through 4.
If your vehicle has a push button start
system:
1. Press START/STOP to switch off your
vehicle.
2. Press the brake pedal and START/STOP
to switch on your
vehicle.
3. Remove your foot from the brake pedal
and press
START/STOP to switch off
your vehicle.

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:
