Parked Regen
General Guidelines
Danger: During parked regeneration, exhaust temperatures are very high, and could cause a fire, heat damage to objects or materials, or personal injury to persons near the exhaust outlet.
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.
A reference label is included with the driver's documentation package initially in the glove box, that explains the ATS warnings, and actions required to avoid further engine protection sequences. See figure .

The regen switch, located on the dash, is used to initiate a parked regen of the aftertreatment device. See figure .
Fig. 2, Regen Switch
Note: The DPF lamp must be illuminated before the regen switch will initiate a parked regen.
An optional regen-inhibit switch provides additional control over the aftertreatment regeneration process. Pressing the bottom of the regen-inhibit switch prevents a regen from occurring while driving. After the vehicle has been shut down and restarted, regens will occur normally unless the inhibit switch is pressed again. See figure .
