The InfoCenter does not show an
icon indicating passive
regeneration.
During passive regeneration, the
DPF processes high-heat
exhaust gasses, oxidizing
harmful emissions, and burning
soot to ash.
The InfoCenter does not show an
icon indicating assist
regeneration.
During assist regeneration, the
engine computer adjusts the
engine settings to raise the
exhaust temperature.
Refer to Assist DPF
Regeneration.
When the high exhaust-
temperature icon
