Refueling Important safety notes G Warning! Gasoline and diesel fuels are highly flammable and poisonous. They burn violently and can cause serious injury. Never allow sparks, flames or smoking materials near gasoline or diesel fuel! Turn off the engine before refueling. Whenever you are around gasoline or diesel fuel, avoid inhaling fumes and any skin or clothing contact. Extinguish all smoking materials. Direct skin contact with fuels and the inhalation of fuel vapors are damaging your health. G Warning Overfilling of the fuel tank may create pressure in the system which could cause a gas discharge. This could cause the gasoline to spray back out when removing the fuel pump nozzle, which could cause personal injury.

G Warning! Do not fill diesel tanks with gasoline. Do not mix diesel fuel with gasoline. Otherwise the fuel system and engine could be damaged. In addition, the vehicle could catch fire.
! Do not use gasoline to refuel vehicles with a diesel engine. Do not use diesel to refuel vehicles with a gasoline engine. 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. You can find further information under "Fuel" (Y page 388), by consulting an authorized Mercedes-Benz Center or visiting http://www.mbusa.com (USA only).
Diesel Fuel grade ! Only refuel with ULTRA-LOW SULFUR DIESEL FUEL (ULSD, 15 ppm SULFUR MAXIMUM). Using other diesel fuels could result in increased wear and damage to the engine and/or exhaust system. Never refuel with marine diesel or heating oil. Do not mix these fuels with diesel fuels and do not use any special additives, as this may result in damage.
! Use a filter when adding fuel from a fuel can. Otherwise, the fuel lines and/or the fuel injection system could be blocked by particles from the fuel can.
