Extended Idling
CAUTION
Prolonged periods of idling can result
in lower than optimal engine/transmis-
sion operating temperatures, which
can cause increased rates of wear.
Do
not allow the engine to operate at
idle for extended periods at temper-
atures at or below 160°F (71°C).
To
help prevent this from occurring on
PACCAR engines, an idle shutdown
feature can be programmed to shut
the engine down after a period of low
idle operation with no driver activity. A
flashing warning light will inform the
driver of an impending shutdown. Fail-
ure to comply may result in equipment
or property damage.
CAUTION
If the truck is equipped with Power
Take-off (PTO) equipment, the engine
shutdown system can be deactivated
when the PTO is operational; however,
engine idle periods should not exceed
five minutes whenever possible. Fail-
ure to comply may result in equipment
or property damage.
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 present 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
Do not ignore the diesel particulate fil-
ter (DPF) warning light. The warning
light alerts the operator that the DPF
should be regenerated. If soot is al-
lowed to fill the DPF and a regenera-
tion is not performed, the DPF will be-
come clogged, requiring it to be re-
moved and cleaned. Failure to comply
may result in equipment or property
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.
