Controls

You can think of the order of the menus and of the functions within a menu as a circle:

Press the mbsymb5_inv_0056.png or mbsymb5_inv_0055.png button repeatedly.

The menus are displayed successively.

Press the mbsymb5_inv_003a.png or mbsymb5_inv_0039.png button repeatedly.

The functions in the menu/submenu are displayed successively.

Several functions are combined thematically in the menus.

The display changes when you press one of the buttons on the steering wheel. You can use a function to call up information or to change the settings for the vehicle.

For example, the AUDIO menu has functions for operating the radio or CD player.

Unlike in other menus, you will find submenus in the Settings menu. For information on how to use these submenus, see the "Settings menu" section more.

The number of menus depends on your vehicle's equipment.

../../../../global/pictures_mb/symb_info.png

Controlling the audio equipment using the steering wheel buttons and making settings via the AUDIO menu only functions with Mercedes-Benz audio equipment. If you are using audio equipment from another manufacturer, the described functions may be restricted or not available at all.
