Mercedes Bluetooth Instructions

Updated April 17, 2017

In Bluetooth-compatible Mercedes Benz vehicles, you can answer your phone by pressing a button on the steering wheel to talk on your phone through the audio system speakers. This allows you to talk on the phone hands-free while you are driving, a safer option than holding the phone to your ear. Bluetooth may come standard or as an extra option depending on the type of Mercedes model.

Turn on Bluetooth on your cell phone. The instructions for activating Bluetooth are different for each cell phone model.

Press the "Tel" key on your radio to bring up the telephone display on the screen located above your radio.

Choose the "Phone" tab in the lower left corner of the screen. Select the tab by moving the controller located in your centre console.

Choose "Phone List," then "Options," then "External Authorization."

Once the screen says, "Ready for External Authorization," your cell phone will search for Bluetooth devices. On your phone's Bluetooth page, you should see "MB Bluetooth" once the phone has discovered the vehicle's Bluetooth.

Once the vehicle detects your cell phone, the screen will read, "Do you want (name of your phone) to be Authorized?" Select "Yes" to authorise your phone.

Enter a passcode on the Mercedes screen when prompted. The passcode can be 1 to 16 digits, but Mercedes recommends at least 4 digits. Select "OK" when you are finished. Enter this same passcode on your cell phone when prompted to do so.

Select your phone from the "Update" list on the Mercedes screen. Once the connection is complete, you will see your phone in the bottom left corner of the main "Telephone" screen.
