Natural gas 3 84, 3 147. Diesel particle filter
The
diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
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. Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If the filter requires cleaning and
previous driving conditions did not
enable automatic cleaning, control
indicator
! flashes.
