Pairing
A Bluetooth enabled cell phone must be paired to the Bluetooth system and then connected to the vehicle before it can be used.
See the cell phone manufacturer's user guide for Bluetooth functions before pairing the cell phone. If a Bluetooth phone is not connected, calls will be made using OnStar Hands-Free Calling, if equipped.
See OnStar Overview on page 14‑1 for more information.
