The first use of a mobile phone via the Mercedes S-Class Commands (W221) system requires that you perform an authorization. To do this:
- Including Bluetooth on the phone and in the Commands system.
- Open the Phone menu by pressing the TEL/NAVI button.
- Select "Data/View" from the menu and confirm the selection.
- Choosing "Bluetooth Phones" and then selecting "Actualize".
- After the system detects the phone, select it from the list, and then click Options.
- We click on the controller twice, confirming the authorization.
- Enter the telephone access code (entering the code in the Commands system first, then duplicating it on the phone). It can consist of 1-16 digits.
- Authorization complete.
