2020 FORD F-450 glow plug

preventing engine damage due to lack of
proper lubrication. After the 30 second
warm-up period, the accelerator pedal
becomes operational again and a message
appears informing you the vehicle is ok to
drive.
When you start the engine in extremely
cold temperatures -15°F (-26°C), we
recommend that you allow the engine to
idle for several minutes before you drive
the vehicle.
Before starting the engine check the
following:
• Make sure all occupants fasten their
seatbelt.
• Make sure the headlamps and
electrical accessories are off.
• Make sure the parking brake is on.
• Make sure the transmission is in park
(P).
Note: Do not press the accelerator during
starting.
Vehicles with an Ignition Key
Note: Do not touch the accelerator pedal.
1. Fully press the brake pedal.
2. Turn the key to position
II
Note: A message appears: Engine Start
Pending, Please Wait.
3. Wait until the engine glow-plug indicator turns off.
4. Turn the key to position
III to start the
engine.
5. When the engine starts, release the brake pedal.
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine does not start, switch the
ignition off and wait 30 seconds before
trying again. Vehicles with Keyless Start
Note:
Do not touch the accelerator pedal.
Note: If the push button ignition switch is
pressed again prior to the engine starting,
the ignition switches to accessory mode and
does not start.
Note: If you release the brake pedal before
the engine starts, follow the engine start
sequence again.
1. Fully press the brake pedal.
2. Press the center of the push button ignition switch.
Note: A message appears: Engine Start
Pending, Please Wait.
3. When the engine starts, release the brake pedal.
Diesel Engine Fast Start Glow Plug
System
The diesel engine glow system consists of:
• Eight glow plugs, one per cylinder.
• Glow Plug Control Module.
• Engine Coolant Temperature sensor.
• Barometric pressure sensor.
• Environmental temperature sensor.
The powertrain and glow plug control
modules electronically control the glow
plug system. After you switch the ignition
on, the glow plug control module
immediately energizes the glow plugs. The
glow plug control module uses the engine
coolant temperature, barometric pressure
sensor and environmental temperature
sensor to determine how long the glow
plugs stay energized. The required time for
the glow plugs to be energized decreases
as the coolant temperature, barometric
pressure and environmental temperature
increase.

Automatic Engine Shutdown
If your vehicle is equipped with a keyless
ignition, it has a feature that automatically
shuts down the engine if it has been idling
for an extended period. The ignition also
turns off in order to save battery power.
Before the engine shuts down, a message
appears in the information display showing
a timer counting down from 30 seconds.
If you do not intervene within 30 seconds,
the engine shuts down. Another message
appears in the information display to
inform you that the engine has shut down
in order to save fuel. Start your vehicle as
you normally do.
Cold Weather Starting
WARNING: Do not use starting
fluid, for example ether, in the air intake
system. Such fluid could cause
immediate explosive damage to the
engine and possible personal injury. WARNING:
Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
We recommend that the engine block
heater be used for starting when the
temperature is -9°F (-23°C) or colder. See
Engine Block Heater
(page 176).
When operating in cold weather, you may
use Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer as needed. Switch the ignition on. Do not
start the engine until the
glow-plug indicator turns off. When the glow plug pre-heat indicator
turns off, turn the key to start. After you
start the engine, the glow plugs may
remain on for a period. If you do not start
the engine before the glow plug activation
time ends, you need to reset the glow plugs
by switching the ignition off. After the
engine starts, allow it to idle for about 15
seconds. This protects the engine. Do not
increase engine speed until the oil pressure
gauge indicates normal pressure.
Cold Weather Operation
Note:
Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Change to a lighter grade engine oil to
make starting easier under these
conditions. Refer to engine oil
specifications. See
Engine Block Heater
(page 176).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See
Engine Block Heater (page
176).

AUXILIARY SWITCHES
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 engine compartment. See your
authorized dealer for service.
The relays are coded as shown:
