The customer center transmits the data to the
service partner that you have entered on the Mercedes me website at: http://
www.mercedes.me. You will then receive individ-
ual recommendations regarding the maintenance of your vehicle.\bThe calculation of the optimal transmission
time of the maintenance request to the service partner is subject to technical limita-
tions that may cause the maintenance recom-
mendation to be perceived as too early or too
late or not to be made at all. In this case, you
can conveniently arrange a maintenance
appointment with the customer center via the
maintenance reminder in the multimedia sys-
tem.\bMaintenance Management and the mainte-
nance reminder in the multimedia system are not available in every country. Contact an
authorized Mercedes-Benz Center to Nnd out
whether this function is available in your coun-
try.

function has been detected may appear in the multimedia system with a request to contact the
Mercedes-Benz customer center. From this mes- sage, a call can be made directly to the customercenter for assistance.\bThe transmission of a notiNcation to the multi-
media system depends on the country, vehi- cle model and equipment and requires a fast
data connection, over which the service pro-
vider has no inOuence.\bReliable fault detection is subject to technical
limitations. Therefore, only a limited selection
of faults can be detected and recommenda- tions for action transmitted to the customer
center and the service partners. Mercedes- Benz AG is continuously working on theexpansion of this service. The fault detection
