Self-diagnosis of Radio/Navigation system (RNS) with multi-function display (MFD)
Table for tyre circumference
Notes:
The correct tyre circumference can be determined for the given tyre sizes from the following table. This can then be used to adapt the tyre circumference on the radio/navigation system.
This is only necessary when the Radio/Navigation system unit is exchanged.
Adaption of the Radio/Navigation system when fitting tyres of another sizes is not necessary as the system will recalibrate itself.
