Procedure and general information
Authorizing a mobile phone (connecting)
If you connect your mobile phone using NFC
(Near Field Communication) the NFC area of
your mobile phone has to touch the NFC logo on
the DVD changer/single DVD drive. The author-
ization then starts automatically. The NFC range
varies depending on the mobile phone and can
be identified by the logo. Further information
(see the manufacturer's operating instructions).
Before using your mobile phone without NFC
with the multimedia system, you will need to
search for the phone (
Ypage 115) and then
authorize it (Ypage 116). Depending on the
mobile phone, authorization either takes place
by means of Secure Simple Pairing or by enter-
ing a passkey. The multimedia system automat-
ically makes the procedure that is relevant for
your mobile phone available. You can recognize
Secure Simple Pairing by the fact that a code is displayed on the mobile phone and on the mul-
timedia system. You can recognize the passkey
system by the fact that you have to enter a code
on the mobile phone and on the multimedia sys-
tem. The mobile phone is always connected
automatically after authorization.
If the multimedia system does not detect your
mobile phone, this may be due to particular
security settings on your mobile phone. You can
also start the search procedure and authoriza-
tion on the mobile phone (
Ypage 116).
Device-specific information on authorizing and
connecting Bluetooth
®-capable mobile phones
can be obtained from an authorized Mercedes-
Benz Center or via the Internet at http://
www.mercedes-benz.com/connect.
You can authorize up to 15 mobile phones. After
authorization, the connection of the last two tel-
ephones used always functions automatically.
Only one mobile phone can be connected to the
multimedia system at any one time.
De-authorizing (disconnecting) a mobile
phone
The connection is terminated automatically if
you leave the receiver range of the multime dia
system or deactivate Bluetooth
®on your mobile
phone.
If you no longer want the Bluetooth
®connection
to be established automatically, the mobile
phone must be de-authorized (disconnected)
(
Ypage 117).

after de-authorizing it, you can choose
another passkey for it.
