E60 Chassis Dynamic: Operation

The DTC and DSC functions can be activated and deactivated by means of the DSC button in the center console switch center (SZM). Briefly pressing the button activates the DTC function. Press the button for a longer period (approx. 3 s) deactivates the DSC function. The ABS function remains active however. The activated DTC function and the deactivated DSC function are indicated by means of warning and telltale lamps in the instrument cluster.

If the DSC button is pressed for longer than 10 s, the DSC function is activated and cannot be deactivated until the next ignition ON. This is a safety function for such a scenario where an object placed on the center console (e.g. a handbag) presses down on the DSC button.
