Notes regarding front passenger seat occupied recognition with Automatic Child Seat Recognition (ACSR) (B48):
If no DTCs are present, the automatic child seat recognition warning lamp (E16, N72e1) illuminates only when the front passenger seat occupied recognition with automatic child seat recognition (ACSR) (B48) has recognized the MB child seat: "Babysafe".
With a non-occupied front passenger seat (either with MB child seat: "Babysafe"or person), the AB, sidebag and ETR are deactivated, therefore the automatic child seat recognition warning lamp (E16, N72e1) will not illuminate.
