BLUETOOTH® HANDS-FREE PHONE SYSTEM
Refer to the Owner's Manual for Bluetooth telephone system operating instructions.
NOTE:
Cellular telephones must have their wireless connection set up (paired) before using the Bluetooth telephone
system.
Bluetooth telephone system allows users who have a Bluetooth cellular telephone to make a wireless connec-
tion between their cellular telephone and the Bluetooth control unit. Hands-free cellular telephone calls can be
sent and received. Personal memos can be created using the NISSAN Voice Recognition system. Some Blue-

tooth cellular telephones may not be recognized by the Bluetooth control unit. When a cellular telephone or
the Bluetooth control unit is replaced, the telephone must be paired with the Bluetooth control unit. Different
cellular telephones may have different pairing procedures. Refer to the cellular telephone operating manual.
Bluetooth Telephone System Diagram
Bluetooth Control Unit
When the ignition switch is turned to ACC or ON, the Bluetooth control unit will power up. During power up, the
Bluetooth control unit is initialized and performs various self checks. Initialization may take up to 10 seconds.
During this time the Bluetooth ON indicator will flash until initialization is complete. If a phone is present in the
vehicle and paired with the Bluetooth control unit, NISSAN Voice Recognition will then become active and the
Bluetooth ON indicator will remain on. Bluetooth telephone functions can be turned off using the NISSAN
Voice Recognition system. For Bluetooth control unit location, refer to AV-43, "
Component Parts and Harness
Connector Location".
Steering Wheel Audio Control Switches
When buttons on the steering wheel audio control switch are pushed, the resistance in steering wheel audio
control switch circuit changes depending on which button is pushed. The Bluetooth control module uses this
signal to perform various functions while navigating through the voice recognition system.
The following functions can be performed using the steering wheel audio control switch:
• Initiate Self Diagnosis of the Bluetooth telephone system
• Start a voice recognition session
• Answer and end telephone calls
• Adjust the volume of calls
• Record memos
Volume Switch
Call volume can be adjusted using the audio unit volume switch.
Bluetooth Microphone
The Bluetooth microphone is located in the roof console assembly. The Bluetooth microphone sends a signal
to the Bluetooth control unit. The Bluetooth microphone can be actively tested during self-diagnosis. For Blue-
tooth microphone location, refer to AV-43, "
Component Parts and Harness Connector Location".
Bluetooth ON Indicator
The Bluetooth ON indicator is located in the overhead console. The indicator will flash during power up while
the Bluetooth control unit is initializing. This process may take up to 10 seconds. If a phone is present in the
vehicle and paired with the Bluetooth control unit, the indicator will remain on to indicate that the system is
ready for voice commands. The indicator flashes during self-diagnosis. For Bluetooth ON indicator location,
refer to AV-43, "
Component Parts and Harness Connector Location".
Audio Unit
The audio unit receives signals from the Bluetooth control unit and sends audio signals to the speakers.

Bluetooth Control Unit Self-Diagnosis Function
INFOID:0000000001704682
The Bluetooth control unit has two diagnostic checks. The first diagnostic check is performed automatically
every ignition cycle during control unit initialization. The second diagnostic check is performed by the techni-
cian using the steering wheel audio control switches prior to trouble diagnosis.
BLUETOOTH CONTROL UNIT INITIALIZATION CHECKS
• Internal control unit failure
• Bluetooth antenna connection open or shorted
• Steering wheel audio control switches (SEND/END) stuck closed
• Vehicle speed pulse count
• Bluetooth Microphone connection test (with playback to operator)
• Bluetooth inquiry check

1. Turn ignition switch to ACC or ON.
2. Wait for the Bluetooth system to complete initialization and the Bluetooth ON indicator to stop flashing.
This may take up to 10 seconds.
3. Press and hold the steering wheel audio control switch SEND
button for at least 5 seconds. The Bluetooth system will begin to
play a verbal prompt.
4. While the prompt is playing, momentarily press both the steering
wheel audio control switches SEND and END buttons simulta-
neously. The Bluetooth system will sound a 5 second beep.
5. While the beep is sounding, momentarily press both the steering
wheel audio control switches SEND and END buttons simulta-
neously again.
6. The Bluetooth system has now entered into the diagnostic
mode. Results of the diagnostic checks will be verbalized to the
technician and the Bluetooth ON indicator will flash. Refer to AV-
49, "Workflow".
7. If there are no failure records to report, the speed pulse count
will be reported next.
8. After the speed pulse count is reported, an interactive Bluetooth microphone test will be performed. Follow
the voice prompt. If the Bluetooth microphone test fails refer to AV-49, "
Workflow".
9. Self-diagnosis mode is complete when the voice prompt says "All diagnostic functions completed". A short
beep is heard.
