Vehicle care 199Speed code letter:Q = up to 100 mphS = up to 112 mphT = up to 118 mphH = up to 130 mphV = up to 150 mphW = up to 168 mphTyre pressureCheck the pressure of cold tyres atleast every 14 days and before anylong journey. Do not forget the sparewheel. This also applies to vehicleswith tyre pressure monitoring system.Unscrew the valve cap.Tyre pressure 3 237 and on the labelon the front left door frame.The tyre pressure data refers to coldtyres. It applies to summer and wintertyres.Always inflate the spare tyre to thepressure specified for full load.The ECO tyre pressure serves toachieve the smallest amount of fuelconsumption possible.Incorrect tyre pressures will impairsafety, vehicle handling, comfort andfuel economy and will increase tyrewear.9 WarningIf the pressure is too low, this canresult in considerable tyre warm-up and internal damage, leading totread separation and even to tyreblow-out at high speeds.If the tyre pressure shall be reducedor increased on a vehicle with tyrepressure monitoring system, switchoff ignition.Tyre pressure monitoringsystemThe tyre pressure monitoring systemchecks the pressure of all four wheelsonce a minute when vehicle speedexceeds a certain limit.All wheels must be equipped withpressure sensors and the tyres musthave the prescribed pressure.The current tyre pressures can beshown in the Vehicle InformationMenu in the Driver InformationCentre.The menu can be selected by thebuttons on the turn signal lever.
