WARNING
Your attention may be distracted from the traffic if you use the radio and
navigation system while driving, resulting in accident.
● You should always drive with due care and attention.
● Select volume settings that allow you to easily hear signals from out-
side the vehicle at all times (e.g. emergency service sirens).
● If the volume is too high, you could damage your hearing. Even if the
volume is too loud for a short period only.
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 turned up high to play an audio source
(e.g. due to very quiet audio output from an external audio source), lower
the volume again before switching audio source.
Additional information and display options
The text displayed on the screen may vary depending on the settings and
may not match the illustrations shown here.
All displays appear only after the radio-navigation system has completed
start-up.
Depending on the vehicle, the changes to the air conditioning settings or
the texts relating to driver assistance systems fitted at the factory are dis-
played. These displays disappear automatically when they are no longer re-
quired.

Telephone control (Phone)
● The “Push to Talk” or “PTT” button on the steering wheel control pan-
el.
● The "Push to Talk" or "PTT" button on the radio and navigation sys-
tem.
When the voice recognition system is activated, an increasing acoustic sig-
nal is heard. The recommendations in the next section ⇒ page 95, Correct
use of the voice control system must be observed for the system to operate
correctly.
DIALOGUE is the time during which the voice control system issues messag-
es and is able to receive spoken orders (commands or oral instructions). If a
call is received, then the dialogue is immediately interrupted.
TIMEOUT is the time that the radio and navigation system waits to receive
an instruction.
Assistance for any of the options available can be requested from any part
of the menu by using the voice instruction HELP. If the TIMEOUT expires and
the user has not given any voice instructions, the system will offer the avail-
able options.
You can CANCEL in any part of the menu.
Basic functions when using voice control
Volume adjustment
The volume can be adjusted at any moment using the navigation system
control button or the buttons on the steering wheel multifunction control.
Connecting voice control (Dialogue)
Briefly press the PTT button on the steering wheel multifunction control
to start the dialogue at any moment.
Briefly press the PTT button on the radio and navigation system to start
the dialogue at any moment. An ascending acoustic signal indicates that the voice control system has
been activated.
Oral instructions (Commands)
Start speaking after the sound signal (beep) which is heard after a DIA-
LOGUE.
If the system does not recognise a spoken instruction, an initial assistance
cue is given, with the available options, and the system waits for a new spo-
ken instruction. After the second failed attempt, the system repeats the sec-
ond part of the assistance cue. If the system still does not recognise the in-
struction on the third attempt, it replies “Process interrupted
” and ends the
dialogue.
Interrupting an on-going message
Briefly press the PTT button on the multifunction control or the naviga-
tion system during a dialogue to end the current message, and to give an-
other command.
Disconnecting voice control (Dialogue)
Briefly press the PTT button on the multifunction control or on the navi-
gation system to end the dialogue at any moment. Now it is possible to
leave the voice recognition system by giving the spoken instruction “CAN-
CEL”.
Press and hold the PTT button to leave the voice recognition system di-
rectly. The voice control system closes with a decreasing acoustic signal.
Correct use of the voice control system
Note the following to ensure that you are properly understood:
● Avoid speaking when the system is saying a cue. Wait for the tone at the
end of the DIALOGUE.
● Try to speak clearly.
