One of these messages stays on until the exhaust filter cleaning has begun, at which time the CLEANING EXHAUST FILTER message displays.
What does cleaning the exhaust filter do?
Cleaning the exhaust filter, sometimes referred to as regeneration, eliminates soot that accumulates during normal operation. Exhaust filter cleaning can occur in several ways. During moderate- to high-load operation, high exhaust temperatures enable “passive” cleaning.
Does a 2007 LBZ have DPF?

How do you clear a blocked DPF filter?
If you get a warning light showing that the filter’s blocked, it should be possible to complete an active regeneration cycle and clear the warning light by driving for 10 minutes or so at speeds over 40mph.
