Diesel Particulate Filter (DPF) Regeneration
Diesel Particulate Filter (DPF)
Collects particulate matter (PM) from the exhaust gas. The DPF is installed in the
catalytic converter.
■
How the DPF Works
The DPF periodically burns off the collected PM while driving at a high temperature
of catalytic converter.
When PM is burned off, you may notice white smoke in the exhaust gas, and the
increase in the average fuel consumption. This is temporary, and normal.

The DPF must operate at a high temperature for the
chemical reactions to take place. It can set on fire any
combustible materials that come near it. Park your
vehicle away from high grass, dry leaves, or other
flammables.
