This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems.
The concept▷Most functions displayed on the Control
Display can be operated by voice com‐
mands via the voice activation system. The
system supports you with announcements
during input.▷Functions that can only be used when the
vehicle is stationary cannot be used via the
voice activation system.▷The system uses a special microphone on

Using voice activation
Activating the voice activation system1. Press button on the steering
wheel.2.Wait for the signal.3.Say the command.
A command that is recognized by the voice
activation system is announced and dis‐
played in the instrument cluster.
This symbol in the instrument cluster indi‐
cates that the voice activation system is active.
If no other commands are available, use func‐
tion via iDrive.
Terminating the voice activation
system
Briefly press the button on the steer‐
ing wheel or ›Cancel‹.
Possible commands Most menu items on the Control Display can
be voiced as commands.
The available commands depend on the menu
that is currently displayed on the Control Dis‐

You may select lists such as phone lists via
voice activation. Read these lists out loud ex‐
actly as they show in the respective list.
Having possible commands read aloud You can have available commands read out
loud for you: ›Voice commands‹
E. g. if the "Settings" menu is displayed, the
commands for the settings are read out loud.
