Even small amounts of the wrong fuel result in damage to the fuel system and engine. ! Do not switch on the ignition if you accidentally refuel with the wrong fuel. Otherwise, the fuel will enter the fuel lines. Notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely. Gasoline Fuel grade ! You should only refuel with unleaded premium-grade gasoline as this avoids damaging the catalytic converter. If engine running problems are apparent, have the cause checked immediately and repaired. Excess unburned fuel can otherwise enter the catalytic converter, leading to overheating and possibly causing a fire. i Only refuel with unleaded premium-grade gasoline with a specified minimum octane number of 91 (average value of 96 RON/ 86 MON). Usually you will find information about the fuel grade on the pump. If you cannot find the label on the gasoline pump, ask the gas station staff.
