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:
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.
