Engine management and
emissions contr
ol system
Introduction
WARNING
●
Due t
o the high temperatures reached by
the exhaust gas scrubbing system, you
should not park your vehicle near a surface
that can catch fire easily. Fire hazard!
●
Do not apply wax underneath the vehicle
around the area of the exhaust system: Fire
hazard!
Control lamps

Fault in the emission control system.
R
educe speed and drive carefully to the nearest spe-
cialised workshop to have the engine checked.
Flashes
Combustion failures that can damage the catalytic
conv
erter.
Reduce speed and drive carefully to the nearest spe-
cialised workshop to have the engine checked.

It lights up
Fault in the petrol engine management.
Hav
e the engine checked as soon as possible by a
specialised workshop.
When the ignition is switched on, the (El
ectronic
Power Control) lights up and should go off once the
engine has started.
Note
While the indicator lamps , or ar
e
on, there might be faults in the engine, fuel
consumption may go up and the engine
might lose power.
Catalytic converter
To maintain the useful life of the catalytic
conv
erter
●
Always use unleaded petrol.
●
Never run the fuel tank dry.
●
When changing or adding engine oil, do not
exceed the necessary amount

Never tow the vehicle to start it, use jump
leads if necessary

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
atmosphere. The catalytic converter can also
be damaged by overheating.
CAUTION
Never run the fuel tank completely dry be-
cause an irr
egular 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.
For the sake of the environment
Even when the emission control system is
w
orking 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.
Particulate filter
The particulate filter eliminates most of the
soot fr
om 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
