Diesel Particulate Filter - Ford F-650 Owner's Manual

Starting and Stopping the Engine
We recommend using the engine block
heater for starting when the ambient
temperature is at or below-9°F (-23°C)
See Engine Block Heater (page 88).
When operating in cold weather, you can
use Motorcraft® cetane improvers or
non-alcohol-based cetane improvers from
a reputable manufacturer as needed.
Do not crank the engine for more than 10
seconds as starter damage may occur. If
the engine fails to start, turn the key to the
off position and wait 30 seconds before
trying again.
Your vehicle may be equipped with a cold
weather starting strategy that prevents
severe engine damage by assisting in
engine lubrication warm-up. In extremely
cold ambient temperatures, this strategy
activates and prevents the accelerator
pedal use for 30 seconds after starting
your vehicle. A message appears in the
information display as your vehicle warms
up. By not allowing the accelerator pedal
use, the engine oil can properly lubricate
the bearings preventing engine damage
due to lack of proper lubrication. After the
30-second warm-up period, the
accelerator pedal is operational again and
a message appears informing you that your
vehicle is ok to drive.
When starting the engine in extremely cold
temperatures, for example -15°F (-26°C),
we recommend you allow the engine to
idle for several minutes before driving your
vehicle.

ignition on as part of the
pre-starting system.
1. Turn the key to the on position without
turning the key to the start position. Do
not start the engine until the wait to
start indicator turns off.

2. When the wait to start indicator turns
off, turn the key to the start position
and release the key as soon as the
engine starts. After starting 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 turning the key to the off position.
3. After the engine starts, allow it to idle
for about 15 seconds. This is to protect
the engine. Do not increase engine
speed until the oil pressure gauge
indicates normal pressure.

DIESEL PARTICULATE FILTER

Your vehicle is equipped with a diesel
particulate filter. The diesel particulate
filter is an inline filter in the exhaust system
that reduces carbon emissions by trapping
exhaust particles before they reach the
tailpipe. The diesel particulate filter looks
similar to a traditional exhaust catalyst,
except larger, and is part of the exhaust
system under your vehicle. The filter
couples to a diesel oxidation catalyst that
reduces the amount of harmful exhaust
emitted from the tailpipe. As soot gathers
in the system, it begins to restrict the filter.
Periodically, you need to clean the soot
that gathers inside the filter. You can clean
the soot in two different ways, passive
regeneration and active regeneration. See
Emission Control System (page 105).
Both methods occur automatically and
require no actions from the driver. During
either one of these regeneration methods,
you may notice a change in exhaust tone.
At certain times, various messages related
to the diesel particulate filter appear in the
information displays.
