Fuel grade
!Do not use diesel to refuel vehicles with agasoline engine. Do not switch on the igni-tion if you accidentally refuel with the wrongfuel. Otherwise, the fuel will enter the fuelsystem. Even small amounts of the wrongfuel could result in damage to the fuel sys-tem and the engine. Notify a qualified spe-cialist workshop and have the fuel tank andfuel lines drained completely.
!Only refuel using unleaded premium gradegasoline with at least 91 AKI/95 RON.
iE10 fuel contains up to 10% bioethanol.Your vehicle is E10-compatible. You canrefuel your vehicle using E10 fuel.
!Only use the fuel recommended. Operatingthe vehicle with other fuels can lead to dam-age to the fuel system, engine and exhaustsystem.
!Do not use the following:
RGasoline with more than 10% ethanol
RE100 (100% ethanol)
RGasoline with methanol
RM100(100% methanol)

Do not mix such fuels with the fuel recom-mended for your vehicle.
!To ensure the longevity and full perform-ance of the engine, only premium-gradeunleaded gasoline must be used.
If standard unleaded gasoline is unavailableand you have to refuel with unleaded gaso-line of a lower grade, observe the followingprecautions:
ROnly fill the fuel tank to half full with regu-lar unleaded gasoline and fill the rest withpremium-grade unleaded gasoline as soonas possible.
RDo not drive at the maximum speed.
RAvoid sudden acceleration and enginespeeds over 3,000 rpm.
You will usually find information about the fuelgrade on the fuel pump. If you cannot find thelabel on the fuel pump, ask the gas stationstaff.
iFor further information, consult a qualifiedspecialist workshop or visithttp://www.mbusa.com (USA only).
GLA 250, GLA 250 4MATIC:as a temporarymeasure, if the recommended fuel is not avail-able, you may also use regular unleaded gaso-line with an octane rating of 88 AKI/93 RON.
All other models:as a temporary measure, ifthe recommended fuel is not available, youmay also use regular unleaded gasoline withan octane rating of 87 AKI/91 RON. This mayreduce engine performance and increase fuelconsumption. Avoid driving at full throttle andsudden acceleration. Never refuel using gaso-line with a lower AKI.
iThe fuels you can use in your vehicle maydiffer from the information in the Operator'sManual depending on the country. The fuelsthat have been approved for your vehiclecan be found on the instruction label on theinside of the fuel filler flap.
