Long periods of idle-time (3 hours or more)
may accelerate the build-up of soot in the
diesel particulate filter (DPF), especially in
cold weather. The system will illuminate the
DPF indicator and a message to indicate
that the DPF requires regeneration. Refer
to the operator manual for more details.
This is not a problem with the vehicle;
however, it indicates that the driver needs
to start a parked DPF regeneration to
prevent equipment damage caused by soot
build up. If the DPF lamp turns ON and the
driver is prompted to through driver
notifications, perform a parked DPF
Regeneration.
CAUTION
If you ignore the warning lamp and do
not initiate regeneration at the soon-
est, safest possible time, the DPF will
become increasingly clogged with soot
and can lead to severe engine derate.
Failure to comply may result in equip-
ment or property damage.
Extended engine idling may also increase
hydrocarbon deposits and moisture in the
DPF. The engine will increase rpm
automatically, regardless if the DPF lamp is
on or off, to remove these hydrocarbon
deposits and moisture. The engine speed
will remain elevated for 20-60 minutes. If
necessary, the rpm may be lowered by
briefly depressing the throttle, clutch, or
brake pedal. If the driver cancels the
automatic cycle using the pedals, the
system will restart the cycle 10 minutes
later with increased rpm until all of the
deposits are removed from the DPF. If the
vehicle cannot perform an automatic cycle,
the driver may be prompted with message
to regenerate the DPF with a "Do Not
Drive" message. The driver must complete
a regeneration before driving. If the "Do
Not Drive" message is ignored and a DPF
regeneration is not fully completed before
driving, there is a high possibility of
equipment damage.
If an engine must idle for an extended
period of time, idle the engine at the lowest
rpm that maintains the engine coolant at
150°F (70°C), or above. Following these
guidelines will help reduce engine wear
during idling and the frequency of DPF
regenerations.
Engine Shutdown
NOTE
DO NOT shut off the engine immedi-
ately. A hot engine stores a great
amount of heat and it does not cool
down immediately after it is shut off.
Always cool the engine down before
shutting it off. You will greatly increase
its service life.
Idle the engine at 1,000 rpm for four
minutes. Then low idle for 30 seconds
before shutdown. This will allow circulating
coolant and lubricating oil to carry heat
away from the cylinder head, valves,
pistons, cylinder liners, turbocharger, and
bearings. This way you can prevent engine
damage that may result from uneven
cooling.
Turn the ignition switch to the OFF
position. If the engine does
not shut down,
contact your dealer.
Electromagnetic Interference
If not installed correctly, some vehicle
accessories (CB radios, mobile
transmitters, etc.) can generate and use
radio frequency energy that may cause
electromagnetic interference (EMI)
