Condition/Concern
In rare instances, if a Bluetooth call is transferred from the vehicle to the phone and, while on that call, a second
Bluetooth call comes in, the customer will hear ringing in the vehicle. Pressing the Push to Talk button on the
steering wheel controls will stop the ringing, but will not answer the second call. If the call is answered from the
phone, the ringing will not stop.
Recommendation/Instructions
The concern has been identified as normal operation. Do NOT replace any parts for this concern.
When a Bluetooth call has been transferred to the handset the VCIM will send incoming ringing from a subsequent
call to the radio. The call must be answered from the handset and the SWC pressed to stop the ringing. Ending the
first call or disconnecting the Bluetooth will also solve the concern.
Customer Information
Please communicate to the customer this condition is a normal operating characteristic of their vehicle. It will not
impact the designed performance or reliability of the vehicle. Please share this information with the customer,
including a copy of this message.
