Fuel

Petrol

On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a

higher octane number than 95 does not result in a noticeable power increase or a

lower fuel consumption.

Grades of petrol

On vehicles with prescribed unleaded petrol min. 95 RON, the use of petrol with a

higher octane number than 95 does not result in a power increase or a lower fuel

consumption.

Your vehicle can only be operated with unleaded petrol, which complies with the

standard EN 228. The individual grades of petrol are distinguished by their octane

number (RON). On the inside of the fuel filler flap, you will find the information

regarding the RON required by your engine  page 145, fig. 141.

The handling, performance and life of your engine are determined to a significant

extent by the quality of the fuel. Do not use any petrol additives.

Diesel

In case of necessity, you can refuel with petrol 91 RON if petrol 95 RON is not avail-

and exhaust system.

 If by mistake you have refuelled with a different fuel other than the diesel fuel

which complies to the above mentioned standards (e.g. petrol), do not start the engine

or switch on the ignition! This can result in severe engine damage! Contact a specialist

garage and have the fuel system of the engine cleaned.

 Water which has collected in the fuel filter can result in engine problems.

 Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must not be

refuelled and driven. The use of biofuel (RME) can lead to damage to the engine or the

fuel system.

Winter-grade diesel fuel

A different grade of diesel fuel is available at filling stations in winter than during the

summer. Using “summer-grade diesel fuel” at temperatures below 0°C can result in

operational problems because the diesel becomes viscous as a result of paraffin sepa-

ration.

It is therefore the case that EN 590 prescribes diesel fuel class for certain periods of the

year which can also be purchased at the corresponding time during the year. “Winter-

grade diesel fuel” will still operate properly even at a temperature of -20°C.

It is often the case in countries with different climatic conditions that diesel fuels avail-

safety reasons. The canister can be damaged in the event of an accident and

fuel may leak out.
