Volume
The volume is normally adjusted using the volume control underneath the centre display or with the right-hand steering wheel keypad. This applies, for example, during playback of music, radio*, ongoing phone calls and active traffic messages.
When adjusting the volume, an expandable menu opens in the centre display. The volume for incoming calls, notifications and media player, for example, can be changed here.
For more sound settings, go to settings 
and tap on Sound.
Sound reproduction
The sound system is pre-calibrated by means of digital signal processing. This calibration takes into account speakers, amplifiers, passenger compartment acoustics, listener position, etc. There is also dynamic calibration that takes into account the position of the volume control and the speed of the car.
