194 Driving and operation
Diesel p artic le filter 3
The d iesel pa rticle filter system removes
polluting soot particles out of the engine
exhaust ga ses. The system includes a self-
cleaning function tha t operates
automatically whilst driving. The filter is
cleaned by burning the trapped soot
particles at a high temperature. There ma y
be an increase in fuel consumption,
exhaust smell, and engine cooling fan
opera tion 3 during the self-clea ning
opera tion.
The self-cleaning function cannot operate
autom atic ally during certa in driv ing
situations where the engine does not rea ch
its normal operating tem perature. An
exa mple of this would be driving only short
distances in cold weather. If the filter needs
cleaning and recent d riv ing situations did
not a llow the func tion to automatically
op erate, then the control indicator
!
will
flash. If this occurs, then you may continue
to drive the vehic le normally. The vehicle
will not be d amaged and does not require
service.
The self-c leaning function will
automatically operate whilst d riv ing after
the engine has reached its normal
operating temperature. The control
indicator ! will continue to flash until the
self-cleaning op eration is complete. This
ma y take up to 20 minutes of driving. The
time will be shorter at higher v ehicle
speeds. If the vehicle is not moving for
more than a few minutes, then the self-
cleaning function will not operate.
Operation will continue when driving
resumes.
