Diesel particle filter
3
The diesel particle filter system filters
harmful soot particles out of the exhaust
gases. The system includes a self-cleaning
function that run automatically during
driving. The filter is cleaned by burning off
the soot particles at high temperature.
This process takes place automatically
under set driving conditions and may take
up to 25 minutes. Fuel consumption may
be higher during this period. The emission
of smells and smoke during this process is
normal.
Picture no: 18600S.tif
Under certain driving conditions, e.g. short
journeys, the system may not clean itself
automatically.
If the filter requires cleaning and previous
driving conditions did not enable
automatic cleaning, control indicator !
flashes.
