•
A steadily illuminated HEST lamp alerts the
operator of high exhaust temperatures when
vehicle speed is below 5 mph (8 km/h) while it
is performing an automatic regen, and during a
parked regen.
•
An illuminated DEF warning lamp in the gauge,
indicates that the DEF tank should be refilled
at the next opportunity.
Parked Regen
DANGER
During parked regeneration, exhaust tempera-
tures are very high, and could cause a fire, heat
damage to objects or materials, or personal in-
jury to persons 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.
A reference label is included with the driver's docu-
mentation package initially in the glove box, that ex-
plains the ATS warnings, and actions required to
avoid further engine protection sequences. See
Fig. 4.3.
The regen switch, located on the dash, is used to
initiate a parked regen of the aftertreatment device.
See Fig. 4.4.
NOTE: The DPF lamp must be illuminated be-
fore the regen switch will initiate a parked
regen.
To initiate a parked regeneration, perform the follow-
ing steps.
1. Park the vehicle away from all combustible and
flammable materials. Chock the tires. Start and
warm the engine until the coolant temperature is
at least 150°F (66°C).
2. Set the parking brake. If the parking brake was
already set, it must be released, then set again.
For manual transmissions, fully depress the
clutch pedal, put the transmission in neutral, then
release the pedal.
If the vehicle has a two-pedal automated trans-
mission, shift it into gear, then back to neutral.
IMPORTANT: The driver must remain with the
vehicle during the entire regen cycle.
3. Press and hold the regen switch for 4 seconds.
The engine will increase rpm and initiate the
regen process.
4. The regen cycle will finish after 20 to 60 minutes,
at which time engine idle speed will drop to nor-
mal and the vehicle can be driven normally. The
HEST lamp may be illuminated, but will go out
when the 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, engage the clutch, brake, or accelerator
pedal, or turn off the engine.
