Driving and operating 919 WarningDo not let this special safetyfeature tempt you into taking riskswhen driving.Adapt speed to the roadconditions.Control indicator b 3 60.FuelFuel for petrol enginesOnly use unleaded fuel that complieswith DIN EN 228.Fuels with ethanol content greaterthan 5% may only be used if thevehicle has been specificallydeveloped and approved for thesefuels.Use fuel with the recommendedoctane rating 3 132. Use of fuel withtoo low an octane rating can reduceengine power and torque and slightlyincreases fuel consumption.If the RON 95 label is attached to thetank flap, unleaded fuel with anoctane rating of 95 or higher must beused.CautionUse of fuel with too low an octanerating could lead to uncontrolledcombustion and engine damage.Fuel for diesel enginesOnly use diesel fuel that complieswith DIN EN 590. The fuel must havelow sulphur content (max. 50 ppm).Equivalent standardised fuels witha biodiesel (= FAME according toEN14214) content of max. 7% byvolume (like DIN 51628 or equivalentstandards) may be used.Do not use marine diesel oils, heatingoils or entirely or partially plant-baseddiesel fuels, such as rape seed oil orbio diesel, Aquazole and similardiesel-water emulsions. Diesel fuelsmust not be diluted with fuels forpetrol engines.The flow and filterability of diesel fuelare temperature-dependent. Whentemperatures are low, refuel withdiesel fuel with guaranteed winterproperties.
