If you mix diesel fuel with petrol, the flash point of the fuel mixture is lower than that of pure diesel fuel.
While the engine is running, component parts in the exhaust system may overheat without warning.
Even small amounts of the wrong fuel could result in damage to the fuel system, the engine and the emission control system.
In countries without sulphur-free diesel fuel, refuel using only low-sulphur diesel fuel with a sulphur content less than 50 ppm.

Refuel your vehicle with as much winter diesel fuel as possible at the beginning of winter.
Before changing over to winter diesel fuel, the fuel tank should be empty, if possible. When first refuelling with winter diesel fuel, only refuel using a small amount, e.g. to reserve level. The fuel tank can be filled as usual when next refuelling.
Further information on fuel can be obtained at a filling station or a qualified specialist workshop.
