called "regeneration" is started in order to burn
away the particles and empty the filter. This
requires the engine to have reached normal
operating temperature.
Regeneration of the filter takes place automat-
ically at an interval of approximately
300 – 900 km depending on driving conditions.
Regeneration normally takes 10 - 20 minutes.
It may take a little longer at a low average
speed. Fuel consumption may increase slightly
during regeneration.
The rear window heating may be activated
automatically to increase the load on the
engine during regeneration without warning.
Regeneration in cold weather
If the car is frequently driven short distances in
cold weather then the engine does not reach
normal operating temperature. This means that
regeneration of the diesel particle filter does
not take place and the filter is not emptied.
When the filter has become
approximately 80% full of particles, the yellow
information symbol on the instrument panel
illuminates, and the message
SOOT FILTER
FULL SEE OWNER MANUAL
is shown on the
instrument panel display.
Start regeneration of the filter by driving the car
until the engine reaches normal operating tem-
perature, preferably on a main road or motor-
way. The car should then be driven for approx-
imately 20 minutes more.
NOTE
A smaller reduction of engine power may be
noticed temporarily during regeneration.
When regeneration is complete the message is
cleared automatically.
IMPORTANT
If the filter fills up it may be incapable of
functioning. Then it can be difficult to start
the engine and there is a risk that the filter
will have to be replaced.
Use the parking heater* in cold weather so that
the engine reaches normal operating tempera-
ture more quickly.
