- Next the telephone asks you to en-ter an identifi cation code : 1234.
- Validate.
Notes:
This entry may be demanded ear-lier in the twinning sequence.
The telephone is now twinned to your Bluetooth system. For imme-diate access to the Bluetooth func-tions, it may be necessary to make a connection (see following page, Confi guration : Connecting a twinned mobile telephone).Once the twinning is fi nished, you will be able to connect your tele-phone via the “Main menu”.
Connecting a twinned telephone
Each time you enter the vehicle, after switching on the audio sys-tem, your telephone is detected
automatically. If more than one telephone is present, the last telephone to have been connect-ed is the fi rst to be recognised.
Note :
Disconnections may occur. You may have to make a new connec-tion (see following page, Confi gu-ration : Connecting a twinned mobile telephone).
Observations :
- In the event of a problem, it is recommended to switch your telephone off and then on again.
- If you switch off your telephone within the fi eld of reception of the Bluetooth system on your vehi-cle, the next connection will not be automatic. To restore auto-matic connection, you will have to connect your telephone manually (see following page, Confi gura-tion : Connecting a twinned mobile telephone).
- If you are already in telephone communication when the audio system is turned on, the latter detects the telephone.
- To avoid interference, you are advised not to place your mobile telephone close to your radio.

For this rea-son it is advisable to make enqui-ries with your telephone provider.Prior to any operation :Your display should be lit up (key in position M).Your telephone’s Bluetooth sys-tem must be activated.
Twinning a telephoneTwinning a telephone consists of having it recognised by the Bluetooth system on your vehicle. This then permits an instantaneous connec-tion.Twinning can only be performed with ignition switched on, dis-play illuminated, engine stopped. No other telephone should be connected.The twinning must be performed with the telephone and its Blue-tooth system activated.
Notes : Refer to the user instructions to fa-miliarise yourself with the features of twinning.
