objects or materials, or personal injury to per-
sons near the exhaust outlet.
Before initiating a parked regeneration, make cer-
tain the exhaust outlets are directed away from
structures, trees, vegetation, flammable materi-
als, and anything else that may be damaged or
injured by prolonged exposure to high heat.
To initiate a parked regen, perform the following
steps.
1.
Park the vehicle away from all flammable materi-
als, put the transmission in neutral, and set the
parking brake.
2.
Start and warm the engine until the coolant tem-
perature is at least 150°F (66°C).
3.
Press and hold the regen request switch for five
seconds. As the regen process is initiated, en-
gine rpm increases and the HEST lamp illumi-
nates to indicate extremely high exhaust tem-
peratures.
IMPORTANT: The driver must remain with the
vehicle during the entire regen cycle.
4.
The regen cycle will finish 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 or accelerator
pedal;
•
take the parking brake off;
•
press and hold the regen inhibit switch until
idle returns to normal;
•
shut down the engine.
ATS Warning Lamps
There are three warning lamps that alert the driver of
high exhaust temperature, the need to perform a
parked regen or service the DPF, or of an engine
fault that affects emissions.
See
for an explanation of the ATS warn-
ings, and actions required to avoid engine protection
sequences.
Malfunction Indicator Lamp (MIL)
A steadily illuminated yellow malfunction indicator
lamp (MIL) indicates an engine fault that affects
emissions. See
DPF Status Lamp
When soot accumulates in the DPF and the DPF sta-
tus lamp illuminates, see
, perform a parked
regen or bring the vehicle up to highway speed to
increase the load (thus starting an active regen).
If the DPF status lamp blinks while the CHECK en-
gine lamp is illuminated, initiate a parked regen im-
mediately in order to prevent an engine derate.
If the red STOP engine lamp illuminates with the
blinking DPF lamp and the CHECK engine lamp,
begin a parked regen in order to prevent an engine
shutdown. Park the vehicle and perform a parked
regen.
High Exhaust System Temperature
(HEST) Lamp
Slow (10-second) flashing of the high exhaust sys-
tem temperature (HEST) lamp indicates that a
parked regen is in progress, and the engine’s high
idle speed is being controlled by the engine software,
not the vehicle driver.
Steady illumination of the HEST lamp alerts the
driver of high exhaust temperature during the regen
process if the vehicle speed is below 5 mph (8 km/
h), or during a parked regen. See
