Before initiating a parked regeneration, make
certain the exhaust outlets are directed away
from structures, vegetation, flammable materials,
and anything else that may be harmed by
prolonged exposure to high heat.
To initiate a parked regen, perform the following
steps.
1.
Park the vehicle away from all flammable
materials, put the transmission in neutral, and set
the parking brake.
2.
Start and warm the engine until the coolant
temperature is at least 150°F (66°C).
3.
Select OK when the DPF screen is displayed on
the driver display screen. See
Fig. 13.2. Select
OK again to confirm regen. As the regen process
is initiated, engine rpm increases and the HEST
lamp illuminates to indicate extremely high
exhaust temperatures.
IMPORTANT: The driver is responsible for
ensuring, during the entire regen cycle, that
anything that could be harmed by exposure to
high heat does not come in contact with the
exhaust gases flowing from the outlets.
4.
The regen cycle finishes after 20 to 60 minutes,
at which time engine idle speed drops to normal
and the vehicle can be driven normally. The
HEST lamp is extinguished when vehicle speed
exceeds 5 mph (8 km/h) or the system has
cooled to normal operating temperature.
5.
To stop a parked regen at any time during the
process:
•
depress the clutch pedal, brake pedal, or
accelerator pedal;
•
select OK on the parked regen screen
while the regen is active, then select OK
again to confirm;
