System Description

INFOID:0000000005259513

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 equipped cellular telephone to make a wire-

less connection between their cellular telephone and the AV control unit. Hands-free cellular telephone calls

can be sent and received. Personal memos can be created using the Nissan Voice Recognition system. Some

Bluetooth cellular telephones may not be recognized by the AV control unit. When a cellular telephone or the

AV control unit is replaced, the telephone must be paired with the AV control unit. Different cellular telephones

may have different pairing procedures. Refer to the cellular telephone operating manual and the vehicle

Owner's Manual for more information.

AV CONTROL UNIT

When the ignition switch is turned to ACC or ON, the AV control unit will power up. During power up, the Blue-

tooth feature is initialized and performs various self checks.   Initialization may take up to 10 seconds.  If a

phone is present in the vehicle and paired with the AV control unit, Nissan Voice Recognition will then become

active. Bluetooth telephone functions can be turned off using the Nissan Voice Recognition system.

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 AV control unit 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

MICROPHONE

The microphone is located in the roof console assembly. The microphone sends a signal to the AV control unit.

The microphone can be actively tested during self-diagnosis.
