Filling with fuel - with a fuel can
When filling with fuel (p. 294) from a fuel can,
use the funnel located under the floor hatch in
the cargo area.
IMPORTANT
Statutory provisions relating to storage of
reserve fuel cans in cars vary from country
to country. Check what does apply.
Take care to insert the funnel properly into
the filler pipe. The filler pipe consists of two
opening covers. The funnel must be pushed
past both covers before filling is started.

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.
Filter regeneration takes place automatically
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 approximately
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 the 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 so
that the engine reaches normal operating
temperature 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.
