The hands free command is only required on vehicles with the navigation system. If you don't have nav then just hold the button for two seconds, wait for ready and the tone, then say bluetooth and then pair.
From the manual:
1. Press and hold (the phone button) for two seconds:
• For vehicles without a navigation system, the system responds with “Ready” followed by a tone.
• For vehicles with a navigation system, the system responds with a tone. After the tone say “Hands Free”. The system responds with “Ready” followed by a tone.
2. Say “Bluetooth”. The system responds with “Bluetooth ready” followed by a tone.
3. Say “Pair”. The system responds with instructions and a four digit PIN number. The PIN number will be used in Step 4.
4. Start the Pairing process on the cell phone that will be paired to the vehicle. Reference the cell phone manufacturers user guide for information on this process.
Locate the device named “General Motors” in the list on the cellular phone and follow the instructions on the cell phone to enter the four digit PIN number that was provided in Step 3.
5. The system prompts for a name for the phone. Use a name that best describes the phone. This name will be used to indicate which phone is connected. The system then confirms the name provided.
6. The system responds with “<Phone name> has been successfully paired” after the pairing process is complete.
7. Repeat Steps 1 through 7 for additional phones to be paired.
