Catalytic converter
Observe the following information to help ensure the long-term functionality of the exhaust system and the engine’s
catalytic converter:
—Refuel the vehicle only with fuels that are suitable for the vehicle (→ Identification of fuels).
—Do not run the fuel tank empty.
—Never overfill with engine oil (→ Engine oil).
—Do not tow-start the vehicle. Use jump leads.
If you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and have the vehicle
checked by a correspondingly qualified workshop. Otherwise uncombusted fuel could enter the exhaust system and
thus be discharged into the atmosphere. In addition, emission-relevant components can be damaged by overheating.
A sulphur-like exhaust gas smell can also occur even if the exhaust purification system is functioning
properly.
