In certain driving conditions, the particle filter can not be cleaned automatically, e.g., in continuous city driving. Then this function can be used to force a regeneration of the particle filter. The function cleans the filter from soot particles by increasing the exhaust temperature and thus burn off soot particles. Increase of the exhaust temperature takes place automatically during the regeneration procedure.
The exhaust temperature is very high during this procedure. Therefore, perform the regeneration outdoors, without connected exhaust hose. The regeneration procedure may take up to 40 minutes.
