Empty tank and diesel engine
Once the engine has stopped due to fuel starva-
tion, the fuel system needs a few moments to
carry out a check.
Before starting the car after the fuel tank has
been filled with diesel - proceed as follows:
1. The remote control key must be inside the
car.
2. Put the car in the ignition position II - turn
the start knob clockwise without pressing the
brake pedal or clutch pedal for cars with
manual gearbox, and hold the start knob for
approx. 4 seconds. Then release the knob,
which automatically returns to its starting
position.
3. Wait approx. one minute.
4. Start the engine.
NOTE
Before filling with fuel in the event of fuel
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.
Points to remember when filling with a
fuel can
When filling diesel with a fuel can, use the funnel
located under the floor hatch in the cargo area.
Make sure you insert the funnel's pipe firmly into
the filler pipe. The filler pipe has two opening
caps. The funnel's pipe must be pushed past
both caps before filling can be started.

STARTING AND DRIVING
Diesel particulate filter
Diesel cars are fitted with particle filters for more
efficient emission control.
Particles in the exhaust gases are collected in
the diesel particle filter during normal driving.
When these conditions have been met, regenera-
tion starts to burn off the particles and empty the
filter. To start regeneration, the engine must have
reached normal operating temperature. Regener-
ation of the particulate filter is automatic and nor-
mally takes 10-20 minutes.
NOTE
The following may arise during regeneration:
a smaller reduction of engine power may
•
be noticed temporarily
fuel consumption may increase temporar-
•
ily
a smell of burning may arise.
•
Use the parking heater* in cold weather - the
engine then reaches normal operating tempera-
ture more quickly.
IMPORTANT
If the filter is completely filled with particles, it
may be difficult to start the engine and the fil-
ter is non-functional. Then there is a risk that
the filter will need to be replaced.
