Additional display information
Depending on the vehicle specification, changes to air conditioning settings
or information on factory-fitted driver assistance systems may be temporarily
displayed on the screen. These displays disappear automatically when they
are no longer required.
All displays appear only after completely restarting the radio system.Caution
Only a small amount of pressure is needed to operate the unit.
Note
•Never press a button down for longer than 10 minutes. Otherwise the
system will interpret this as a malfunction ( button jammed).•Due to country-specific legislation, certain functions cannot be selected
on the screen when the vehicle is travelling above a certain speed.•Using a mobile phone in the vehicle may cause noise from the vehicle
speakers.•In some vehicles equipped with a parking distance warning system, the
volume of the current audio source is automatically lowered when reverse
gear is engaged. This volume can be changed while reverse is engaged. If the volume is not modified, when reverse is disengaged the previous volume
setting is restored. If the volume is modified, when reverse gear is disen-
gaged the audio source will stay at the set volume and, as long as the
maximum volume is not exceeded, it will be memorised for the next time
reverse gear is engaged.
Switching on and offWhen the unit is switched on the system starts up. The last audio source used
is played at the last selected volume setting, provided this does not exceed
the preselected “switch-on volume” (
ON-VOL ⇒ page 34).
Energy management
If, when the ignition is switched off and the unit switched on, the battery
voltage falls below the minimum onboard power supply voltage, a signal
sounds and LOW BATTERY appears. You should switch the radio off.
If the battery voltage level continues to fall, LOW BATTERY and RADIO OFF are
briefly shown on the display. The unit will switch off automatically.Function

Adjusting the base volumeAt “0” the unit is muted (display:
) and any media source currently being
played will be stopped.
Changes to the volume are indicated by a “bar” on the screen.
It is possible to preset certain volume settings and adjustments ⇒ page 34.
Caution
If the volume is too high or the sound is distorted, the vehicle speakers may
be damaged.
Note
If the base volume has been considerably increased on the radio system to
play a certain audio source (e.g. due to very quiet audio output from an
external audio source), lower the volume again before switching audio
source.
Names of controlsOverview•Rotary/push knobs•Labelled unit buttons (hard keys).•Function buttons (soft keys).
