Audio/COMAND operating instructions, general 

This description attempts to present operation of the full functional scope for the head unit (A26/17) while taking all the vehicle's standard and special equipment, as known at the copy deadline, into account.

National-specific and equipment-specific deviations hereto are possible. The vehicle is equipped with digital operating instructions, which can be called up on the driver information system.

IMPORTANT Digital operator's manual: The language of the operator's manual can be selected from the language packages offered for different national versions. Content can be called up through the table of contents, a visual search on the vehicle or using a keyword.

IMPORTANT The digital operator's manual also provides animations.

The functions and menu navigation for the driver information system are shown on the Audio/COMAND display (A40/8). The driver information system can be operated with the following controls:

Audio/COMAND control panel (except code 446 (Touchpad only)) 

The Audio/COMAND control panel is located on the center console. As the main control, the Audio/COMAND control panel includes the Audio/COMAND controller (A40/9s11), which makes navigation in menus and lists, the selection of display-generated buttons (softkeys) and the entry of characters possible by tilting, pressing and turning. The "Back" button (A40/9s2) and the "Home" and "Favorite" button (A40/9s16) support menu navigation. Using the "Back" button, you can switch to the last display with a short press and switch to the main menu with a long press. The main menu and functions that have been saved as favorites can be called up using the "Home" and "Favorites" buttons.

Touchpad (with code 446 (Touchpad only) or with code 448 (Touchpad))

The touchpad also recognizes when the integrated buttons are pressed. The active audio source can be operated using the Background Audio button (A105s2) in a pop-up window at the bottom edge of the screen without having to close the menu that is currently open.

On vehicles with code 448 (Touchpad), the touchpad must be switched on via the vehicle menu in the head unit.

For the greater touch touchpad with code 446 (Touchpad only), the Audio/COMAND control panel must be omitted due to the limited installation space on the center console.

The voice control system is switched on and off with voice control ON switch and favorites (S163/2s17) of the head unit multifunction steering wheel button group. With the voice control system switched on, numerous equipment dependent functions of the driver information system (e.g. navigation, radio and media sources, telephony, vehicle menu) can be operated via voice command in dialog with the VCS. The voice control system recognizes coherent commands that can be spoken by any person (e.g.: "Navigate to MercedesstraBe 87 in Stuttgart"), without the need for teach-in. If the message of the voice command is not clearly identified, a query is made by the voice control system.
