06 During your journey
Fuel
tank may need to be vented in the workshop in
order to restart the engine after fuelling.
Once the engine has stopped due to fuel star-
vation, the fuel system needs a few moments
to carry out a check. Do this before starting the
engine, once the fuel tank has been filled with
diesel:
1. Insert the remote control key in the ignition
switch and push it in to the end position
(see page 80).
2. Press the START button without depress-
ing the brake and/or clutch pedal.
3. Wait approx. 1 minute.
4. To start the engine: Depress the brake and/
or clutch pedal and then press the
START button again.
NOTE
Before filling with fuel in the event of fuel
06
shortage:
•
Stop the car on as flat/level ground as
possible - if the car is tilting there is a
risk of air pockets in the fuel supply.
Draining condensation from the fuel filter
The fuel filter separates condensation from the
fuel. Condensation can disrupt engine opera-
tion.

Option/accessory, for more information, see Introduction.
The fuel filter must be drained at the intervals
specified in the Service and Warranty Booklet
or if you suspect that the car has been filled
with contaminated fuel.
IMPORTANT
Certain special additives remove the water
separation in the fuel filter.
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
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 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.
