There are ve DPF levels. DPF warning messages will
appear according to the soot level present. (Figures

It is important to perform a parked
regeneration BEFORE the DPF level reaches Level
4. If the regeneration process is not performed and
the soot level reaches Level 4, non-warranty factory
assistance from the engine manufacturer is required.
Regen Level 1: The DPF is loaded with soot and needs
to be regenerated. (Figure 4-36) This message alerts

automatically regenerate. This only applies at
DPF Level 1 and 2.
