Diesel particle filter (DPF)
Diesel cars are equipped with a particle filter,
which results in more efficient emission con-
trol. The particles in the exhaust gases are col-
lected in the filter during normal driving. So-
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.
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, a warning triangle on the
instrument panel illuminates, and the message
Soot filter full. See manual
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 warning
text is cleared automatically.
Use the parking heater* in cold weather so that
the engine reaches normal operating tempera-
ture more quickly.
IMPORTANT
If the filter fills up with particles then it can
be difficult to start the engine and the filter
will be incapable of functioning. Then there
is a risk that the filter will have to be
replaced.
Fuel consumption
Fuel consumption figures may change if the car
is equipped with extra equipment that affects
the car's weight. See information about
weights, page 347.
is shown on the
The manner in which the car is driven, and
other non-technical factors can also affect fuel
consumption.
Consumption is higher and power output lower
for fuel with an octane rating of 91 RON.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combi-
nation with fuel grade are factors that could
affect the car's performance.
