Regeneration of particle filter

This function cleans the particle filter from soot particles by burning them off using an increase in the exhaust temperature. In certain driving conditions, the particle filter can not be cleaned automatically, e.g., in continuous city driving. Then this function is used to force a regeneration. Regeneration takes approx. 25 minutes and the engine rpm will be increased.
Note:
Run the regeneration process outdoor with no combustible material under or behind the vehicle.Regeneration creates very high exhaust temperatures.
If the engine warning lamp is lit, the DPF system might be abnormal. Check and repair any fault codes before performing the forcible DPF regeneration.
The engine speed increases during regeneration to between 1500 - 2000 r/min and the temperature increases within the diesel particle filter (DPF) and is maintained at approximately 600°C.
The regeneration is performed for about 25 minutes, then the forcible DPF regeneration automatically stops. Depressing the accelerator pedal during the regeneration, however, can cancel the forcible DPF regeneration.
The DPF regeneration is performed when the DPF lamp is illuminated or blinking due to the accumulated amount of particles (PM). The DPF lamp is turned off as soon as the forced regeneration is correctly completed.

Procedure:
  1. Choose the function and follow the instructions.
If the function fails, check the test conditions and repair possible fault codes.
