Observe the following information to help ensure the long-term functionality of the exhaust system and the catalytic converter in the
petrol engine:
—Only use fuel that has been approved for the vehicle.
—Do not run the fuel tank empty (→ Fuel types and refuelling).
—Do not overfill engine oil (→ Engine oil).
—Do not tow-start the vehicle. Use jump leads (→ Jump starting).
If you notice misfiring, loss of power or uneven running when driving, reduce speed immediately and have the vehicle checked by a
suitably qualified workshop . Volkswagen recommends using an authorised Volkswagen repairer. Otherwise unburned fuel can enter
the exhaust system and escape into the environment. The catalytic converter can also be damaged by overheating.
The emissions may have a sulphur-like smell even if the emission purification system is working properly.
