System Description

INFOID:0000000004219431

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 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.

If a phone is present in the vehicle and paired with the Bluetooth control unit, Nissan Voice Recognition will

then become active. Bluetooth telephone functions can be turned off using the Nissan Voice Recognition sys-

tem.

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 unit uses this sig-

nal 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 Bluetooth con-

trol unit. The microphone can be actively tested during self-diagnosis.

AUDIO UNIT

The audio unit receives signals from the Bluetooth control unit and sends audio signals to the speakers.
