General information on voice control
The voice control system VCS [SBS] can be used to call up and regulate the individual functions in the driver information system. The VCS [SBS] is integrated into the COMAND controller unit (A40/3). The system can be controlled by voice by spelling out or entering complete words.

Operating instructions
The voice control is activated or deactivated using the buttons on the multifunction steering wheel (MFL):
^ Voice control system ON button (S111s4)
^ "Back" and voice control system OFF button (S110s4)

Voice control function sequence
The control signal for the VCS [SBS] on button is forwarded over the following components to the COMAND controller unit:
^ Steering LIN
^ Steering column module control unit (N80)
^ Chassis CAN
^ Instrument cluster (A1)
^ Interior CAN

The voice input takes place via the attendant voice control system microphone, which is connected over a discrete line to the COMAND controller unit. The spoken word is converted by the voice control system microphone into an electrical signal and forwarded to the COMAND controller unit. Voice output takes place via the following speakers:
^ Left front door speaker (H4/1)
^ Right front door speaker (H4/2)
^ Center instrument panel speaker (H4/27)

These are discretely connected to the sound system amplifier control unit (N40/3) (with code (810) Sound system).

For vehicles except code (810) Sound system voice output is performed over discrete lines directly by the COMAND controller unit over the following speakers:
^ Left front door speaker
