Vehicle care 187The use of commercially availableliquid tyre repair kits can impair thefunction of the system. Factoryapproved systems can be used.External high-power radio equipmentcould disrupt the tyre pressuremonitoring system.System initialisationAfter a wheel change, the systemmust be initialised: inflate the tyres tothe prescribed pressure, switch onthe ignition, press and hold the DDSbutton for approx. 4 seconds, controlindicator w flashes three times.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 96.System initialisationAfter tyre pressure correction orwheel change, the system must beinitialised: Switch on the ignition,press and hold the DDS button forapprox. 4 seconds, control indicatorw flashes three 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).The legally permissible minimumtread depth (1.6 mm) has beenreached when the tread has worndown as far as one of the tread wear
