Initiating a Stationary (Parked) Regeneration
NOTE
At starting of the engine, if a stationary
regeneration is required, the engine coolant
temperature must reach 140°F (60°C) before
any stationary regeneration may be initiated
and completed. Permit the engine to idle for a
short while or drive the vehicle until engine
temperature increases sufficiently.
WARNING
Do not initiate a stationary regeneration in a
closed area like a garage. Stationary
regenerations must be undertaken outdoors
only.
WARNING
During stationary regeneration, exhaust
temperature may reach up to 1200°F (650°C)
at the particulate filter. Before initiating
stationary regeneration, make sure that the
DPF outlet diffuser is clear of objects and that
no one is working near the DPF outlet diffuser.
WARNING
Hot surfaces. Keep yourself clear of all hot
Aftertreatment Device components, particularly
during and after active or stationary
regeneration. Hot surfaces can cause serious
burns.
NOTE
STATIONARY REGENERATION
This process requires the vehicle to be parked
while the driver or a maintenance technician
initiates the regeneration process.
The DPF REGENERATION telltale light
illuminates to notify the driver of the need and
urgency of a manual stationary regeneration.
DPF REGENERATION telltale light
If stationary regeneration is not performed, this
telltale light will blink, indicating that a stationary
regeneration is required immediately. If
stationary regeneration is still not performed,
“engine power derate and shutdown” sequence
may occur as per level 1 to level 4 sequence.
To initiate a stationary regeneration:

Park the vehicle in a clear area, vehicle
speed must be 0 mph (0 km/h);

Engine must be on normal idle and fully
warmed up (coolant temperature above
140°F/60°C);

Apply parking brakes and set the
transmission to neutral (N).

Press the DID ENTER button and then get to
the DID Aftertreatment menu. Select sub-
menu Request Parked REGEN and press
ENTER button to confirm and initiate
regeneration.
The regeneration will begin. Turn off the air
conditioning to reduce engine load. The engine
idling speed will increase to 1600 rpm. Once the
regeneration is completed, the engine speed will
return to normal idle.
Voluntary Interruption of a Stationary
Regeneration
It is possible to interrupt a stationary
regeneration at all time. To do so, set the
ignition key to the OFF position or get to the
DID’s Aftertreatment menu, select Cancel
REGEN and press ENTER button to confirm.
You can stop regeneration simply by releasing
the parking brake. Use this procedure in order to
move the vehicle in a safe area only.
If regeneration is interrupted, it is very important
to reinitiate the regeneration as soon as possible.
CAUTION
If an active regeneration is stopped
repeatedly, the vehicle may need to be taken
to a service facility. The service facility will use
a service tool to manually initiate the
regeneration. Moreover, the interruption of
active regeneration should not be considered
as a normal practice. Some components of
the aftertreatment system might be damaged
in the long term.
