CAUTION
Fault in the emission control system.
Reduce speed and drive carefully to the nearest spe-
cialised workshop to have the engine checked.
Never run the fuel tank completely dry be-
cause an irregular fuel supply can cause
ignition faults. This allows unburnt fuel to
enter the exhaust system, which could
cause overheating and damage the cata-
lytic converter.
Note
While the control lamps , , or are
on, there might be faults in the engine, fuel
consumption may go up and the engine
might lose power.
Flashes
Combustion failures that can damage the catalytic
converter.
Reduce speed and drive carefully to the nearest spe-
cialised workshop to have the engine checked.
For the sake of the environment
Even when the emission control system is
working perfectly, there may be a smell of
sulphur from the gases on occasions. This
depends on the sulphur content of the fuel
used. This can quite often be avoided by
changing to another brand of fuel.

The particulate filter eliminates most of the
soot from the exhaust gas system. Under nor-
mal driving conditions the filter cleans itself. If
the filter does not clean itself (e.g. if short
journeys are made continuously), it becomes
blocked with soot and the following indica-
tion is displayed to the driver: Particu-
late filter: cleaned while the vehi-
cle is moving. See Manual. The

If you should notice misfiring, uneven running
or loss of power when the car is moving, have
the vehicle inspected by a specialised work-
shop. In general, the emissions warning lamp
will light up when any of these symptoms
occur. If this happens, any unburnt fuel can
enter the exhaust system and escape into the
Diesel engine preheating system.
The engine can be started straight away when the
lamp switches off.
