Notes for Service department
General notes
NOTE:
Different vehicle settings!
Diverse vehicle settings are available on the radio. For example, the opening angle of the automatic tailgate activation (SA316).
NOTE:
Installation of DC/DC converter!
The more frequent starting operations of the vehicles with automatic Start/Stop function (MSA) may result in voltage dip in the vehicle system. To protect certain components that are sensitive to voltage, 1 or 2 DC/DC converters are installed (depending on the vehicle equipment).
