Engine management system fault
(Electronic Power Control).
The engine should be checked by a qualified
workshop as soon as possible.
Fault in catalytic converter.
Decrease speed. Drive carefully to the next
qualified workshop. The engine should be
checked.
FlashesPossible causeSolution
Misfiring, which damages the catalytic
converter.
Decrease speed. Drive carefully to the next
qualified workshop. The engine should be
checked.
Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will go out soon afterwards.
If the indicator lamps  or are lit up, fuel consumption may be higher, and engine
performance reduced.
Catalytic converter
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The catalytic converter is used for exhaust gas post-treatment and helps to reduce exhaust
emissions. To help ensure long-term functionality in the exhaust system and the catalytic converter:
•Use unleaded petrol only.
•Do not allow the fuel tank to run empty.
•Do not overfill engine oil ⇒ Engine oil.
•Do not tow-start the vehicle. Use jump leads ⇒ Starting the engine with jump leads.
If you notice misfiring, uneven running or loss of power when the vehicle is moving, reduce speed
immediately. The vehicle should be inspected at the nearest qualified workshop. If this happens,
unburnt fuel can enter the exhaust system and escape into the atmosphere. The catalytic converter
can also be damaged by overheating.
Even when the exhaust purification system is working perfectly, there may be a smell of
sulphur from the exhaust in some conditions. This depends on the sulphur content of the fuel being
used.
The components of the exhaust system become very hot. This can cause fires.
•Park the vehicle so that no part of the exhaust system can come into contact with any
inflammable material underneath the vehicle, e.g. dry grass.
•Never apply additional underseal or anti-corrosion coatings to the exhaust pipes, catalytic
converters or heat shields.
WARNING
To avoid damage to your vehicle, always observe the indicator lamps and associated warning
texts.
