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).
As a temporary measure, if the recommendedfuel is not available, you may also use regularunleaded gasoline with an octane rating of87 AKI/91 RON. This may reduce engine per-formance and increase fuel consumption.Avoid driving at full throttle and sudden accel-eration. Never refuel using gasoline with alower 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.
Information on refueling (Ypage 133).
