Pairing a Phone
1. Press and hold 
for two seconds.
2. Say “Bluetooth.” This command can be skipped.
3. Say “Pair.” The system responds with instructions and a four-digit Personal Identification Number (PIN). The PIN is used in Step 5.
4. Start the pairing process on the cell phone that you want to pair.
For help with this process, see the cell phone manufacturer's user guide.
5. Locate the device named “Your Vehicle” in the list on the cell phone. Follow the instructions on the cell phone to enter the PIN provided in Step 3. After the PIN is successfully entered, the system prompts you to provide a name for the paired cell phone.
This name will be used to indicate which phones are paired and connected to the vehicle. The system responds with “<phone name> has been successfully paired” after the pairing process is complete.
6. Repeat Steps 1 through 5 to pair additional phones.
