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, NIS SAN Voice Recognition will then become active and the
Bluetooth ON indicator will remain on. Bluetooth te lephone functions can be turned off using the NISSAN
Voice Recognition system. For Bluetooth control unit location, refer to AV-44, " 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

tooth microphone location, refer to AV-44, " 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 indi cator will remain on to indicate that the system is
