If you are driving your vehicle in a manner to allow effective cleaning, 
the information display shows a message to indicate that automatic 
regeneration is in progress.

If you are not driving your vehicle in a manner to allow effective 
cleaning, the information display shows a message to suggest that you 
drive in a manner to allow automatic regeneration.

Manual Regeneration with Automatic Regeneration Control

Where vehicle use has significant engine idle operation, frequent 
vehicle speed less than 40  km/h, or driving short distances where the 
engine does not fully warm up, automatic regeneration may not 
sufficiently clean the diesel particulate filter. You can switch 
automatic regeneration off until you can drive your vehicle in a manner 
to allow effective cleaning, for example at a steady vehicle speed of 48 
  km/h or above for approximately 20 minutes. You can then switch 
automatic regeneration back on to clean the diesel particulate filter.
