170 Vehicle careTyre pressure 3 212 and on the labelon the inside of the fuel filler flap or onthe front right 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.Tyre deflation detectionsystemThe tyre deflation detection systemcontinually checks the rotation speedof all four tyres.If a tyre loses pressure the controlindicator w illuminates red. Stopimmediately and check tyre pressure.Control indicator w 3 81.System initialisationAfter tyre pressure correction orwheel change, the system must beinitiated: Switch on the ignition, pressand hold the DDS button for approx.4 seconds, control indicator w flashesthree times.Tread depthCheck tread depth at regularintervals.Tyres should be replaced for safetyreasons at a tread depth of 2-3 mm(4 mm for winter tyres).
