Introduction 33 standard. Only use tyres, wheels and acces- sory parts that are approved for your type of vehicle. Genuine Mercedes-Benz parts and conver- sion parts and accessories that have been approved for your vehicle are tested by Mercedes-Benz for: These data memories temporarily or perma- nently store technical information about: R the vehicle's operating status R malfunctions In general, this technical information docu- ments the state of a component, a module, a system or the surroundings. This includes, for example: R events R reliability R safety R suitability Despite ongoing market research, Mercedes- Benz is unable to assess other parts.
Mercedes-Benz accepts no responsibility for the use of such parts in Mercedes-Benz vehi- cles, even if they have been independently or officially approved. In Germany, certain parts are only officially approved for installation or modification if they comply with legal requirements. This also applies to some other countries. All gen- uine Mercedes-Benz parts meet the approval requirements. The use of non-approved parts may invalidate the vehicle's general operating permit. This is the case if: R operating conditions of system compo- nents, e.g. fluid levels. R the vehicle's status messages and those of its individual components, e.g.
number of wheel revolutions/speed, deceleration in movement, lateral acceleration, accelera- tor pedal position. R malfunctions and defects in important sys- tem components, e.g. the brakes. R the vehicle's reactions and operating sta- tuses in special driving situations. R ambient conditions, e.g. outside tempera- ture. This data is exclusively technical in nature and can be used to: R it results in a change to the vehicle type from that for which the vehicle's general operating permit was granted R assist in the detection and rectification of faults and defects R they pose a possible risk for road users R analyse vehicle functions, e.g.
after an acci- dent R they adversely affect the emission or noise levels Always specify the vehicle identification num- ber (VIN) when ordering genuine Mercedes- Benz parts ( Y page 356). R optimise vehicle functions The data cannot be used to trace the vehicle's movements. When you use one of the available services, technical information may be read from the event data memory and fault data memory. Services include, for example: Data stored in the vehicle R repair services A wide range of electronic components in your vehicle contain data memories.
R service processes R warranty claims R quality assurance It is read by service network employees (including the manufacturer) using special diagnostic testers. Further information is available there if required. Z
