Mercedes-Benz USA, LLC recommends deauthorization in both COMAND and the Bluetooth® device, e.g. the mobile phone.

Subsequent authorization may otherwise fail.

In the Bluetooth® device list, select the authorized device by turning the COMAND controller.

Select Options by sliding the COMAND controller and press to confirm.

Select De-authorize and press to confirm.

A prompt appears asking whether you really wish to de-authorize this device.

Select Yes or No and press to confirm.

If you select Yes, the authorization for the device will be revoked.

If you select No, the process will be aborted.

If a Bluetooth® device has been deauthorized and is out of range, when a new search is carried out it will not appear in the Bluetooth® device list.
