NHTSA's summary

Supersedes Technical Service Bulletin Group 91 number 11-29 dated December 20, 2011. The Bluetooth telephone bonding tone is too loud or quiet for the customer. When a telephone is connected to the vehicle via the Bluetooth wireless connection, a tone is played over the audio system. The volume of this tone correlates to the volume level of the phone preparation voice control. This volume level is independent of the volume during telephone calls.
