Service Information: Recognition of tire size by navigation system - SI82.61-P-0004A

MODEL 211 with CODE (525) MB Audio 50 APS radio with CODE (527) COMAND APS with single DVD drive (with navigation) 

After changing tires, for example, converting to winter tires with different tire size, the navigation system automatically recognizes the new deviating tire size.

For this reason, it is not necessary  to change the tire size with STAR DIAGNOSIS.

Calibration drives no longer  need to be made with the Audio 50 APS and COMAND APS.
