This document provides an overview of the driver information that CAN-Be called up using the Active Service System (ASSYST) via the multifunction display (A1p13) of the instrument cluster (A1). Unless otherwise specified, the display is in white font.
The following information can be displayed:
- Service interval
- Fault and warning message on engine oil
- Oil level measurement messages initiated by driver

For most remaining time or remaining distance displays, the service scope (A or B; 1 or 2 or service symbols) are displayed.
The display language can be selected using the "Settings" function of the instrument cluster (A1).
