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 collec-
ted 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 nor-
mal operating temperature.
Regeneration of the particle filter is automatic
and normally takes 10-20 minutes. It may
take a little longer at a low average speed.
Fuel consumption may increase slightly dur-
ing 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 approx. 80% full
of particles, a yellow warning triangle is
shown in the combined instrument panel, and
the message
Soot filter full See manual is
shown in its information display.
Start regeneration of the filter by driving the
car until the engine reaches normal operating
temperature, preferably on a main road or
motorway. The car should then be driven for
approximately 20 minutes more.
NOTE
The following may arise during regenera-
tion:
•
a smaller reduction of engine power
may be noticed temporarily
•
fuel consumption may increase tem-
porarily
•
a smell of burning may arise.
When regeneration is complete the warning
text is cleared automatically.
Use the parking heater* in cold weather - the
engine then reaches normal operating tem-
perature more quickly.
IMPORTANT
If the filter is completely filled with parti-
cles, it may be difficult to start the engine
and the filter is non-functional. Then there
is a risk that the filter will need to be
replaced.

Filling vehicle gas*
Points to remember when filling vehicle gas
(CNG - Compressed Natural Gas) for cars
with the Bi-Fuel engine alternative.
Filling
Vehicle gas is filled via the gas nipple that is
located next to the fuel cap inside the fuel
filler flap.
1. Open the fuel filler flap and remove the
nipple's protective cover.
2. Push the nozzle towards the nipple and
make sure that the hose nozzle is
attached by turning the handle on the
nozzle to the left.
3. Then hold the start button on the gas
pump depressed for approx. 5 seconds.
> The tank is filled in a couple of
minutes.
4. Remove the nozzle by turning its handle
to the right.
