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.
