Mobile phone pairing
Initial operation
Before it is used for the first time, the hands-
free system is set so that it is "invisible" to
other Bluetooth
®
devices.
Pairing a mobile phone
You must pair a mobile phone once with the
hands-free system. This pairing procedure is
required so that the hands-free system can
identify the Bluetooth
®
mobile phone.
Depending on the mobile phone used, differ-
ing steps are required to carry out this proc-
ess (
N
mobile phone operating instructions).
X Activate Bluetooth
®
on the mobile phone.
X
Switch on the ignition.
The hands-free system is activated auto-
matically.
X
Press the
6
"Accept" button and the
~
"End call" button simultaneously for
at least three seconds.
The blue status LED now flashes slowly and
the hands-free system is visible for the
mobile phone.
Once the mobile phone has found the
hands-free system, it shows the hands-free
system in its list of Bluetooth
®
devices.
X
Select the hands-free system to be con-
nected to on the mobile phone:
The mobile phone prompts you to enter a
four-digit access code.
i The default value of the access code is
3732. A Mercedes-Benz Service Centre
can alter the access code via the vehicle
diagnostics system. This pairing informa-
tion is stored permanently in the hands-
free system.
X
Enter the access code using the mobile
phone keypad.
i
If the mobile phone is connected to the
hands-free system, the blue status LED
lights up for 10 seconds and then goes out
(standard setting).
If there is a problem during the pairing
process, the blue status LED flashes rap-
idly.
On some mobile phones the connection is
not established automatically but must be
specifically activated on the mobile phone
(
N
mobile phone operating instructions).
X
To call up the Bluetooth
®
connection
status: press the
~
"End call" button
on the hands-free system briefly (if there is
no currently active call).
i Any Mercedes-Benz Service Centre can
set the display duration of the Bluetooth
®
connection status via the vehicle diagnos-
tics.
Allocating/reconnecting a mobile
phone
The mobile phone will connect automatically
to the hands-free system in the future, if you
are in the Bluetooth
®
signal area of the hands-
free system. Additionally, Bluetooth
®
must be
activated on the mobile phone and there must
not be any other device connected to the
hands-free system.
i On some mobile phones, the connection
is not established automatically but must
be confirmed each time on the mobile
phone. This can be avoided, by activating
the "always allow" option on the mobile
phone.
Up to four mobile phones can be paired to
the hands-free system, but only one can be
actively connected to the hands-free sys-
tem at a time.
If a fifth mobile phone is paired to the
hands-free system, one of the mobile
phones is removed from the memory of the
hands-free system. This is always the
device that has not been connected to the
hands-free system for the longest time.
