130 Driving and operatingCautionPerformance of the sensors canbe reduced when sensors arecovered, e.g. by ice or snow.Performance of the parking assistsystems can be reduced due toheavy loading.Special conditions apply if thereare taller vehicles involved (e.g.off-road vehicles, mini vans,vans). Object identification in theupper part of these vehiclescannot be guaranteed.Objects with a very small reflectioncross-section, e.g. objects ofnarrow size or soft materials, maynot be detected by the system.Parking assist will not avoid acollision with objects which are outof the detection range of thesensors.NoteThe parking assist systemautomatically detects factory-fittedtowing equipment. It is deactivatedwhen the connector is plugged in.The sensor may detect a non-existent object (echo disturbance)caused by external acoustic ormechanical disturbances.NoteThe parking assist is deactivatedwhen the rear carrier system isextended.FuelFuel for petrol enginesOnly use unleaded fuel that complieswith European standard EN 228 orE DIN 51626-1 or equivalent.Your engine is capable of runningwith E10 fuel that fulfills thesestandards. E10 fuel contains up to10 % bioethanol.Use fuel with the recommendedoctane rating 3 195. Use of fuel withtoo low an octane rating can reduceengine power and torque and slightlyincreases fuel consumption.CautionDo not use fuel or fuel additivesthat contain metallic compoundssuch as manganese-basedadditives. This may cause enginedamage.
