HANDS-FREE PHONE SYSTEM
System DiagramINFOID:0000000001696034
System DescriptionINFOID:0000000001696035
Refer to the Owner's Manual for Bluetoot
h 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 t he AV control unit. When a cellular telephone or the
AV control unit is replaced, the telephone must be pair ed 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 navigati ng 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.

• When there is no vehicle ahead, drive at the set speed steadily.
• When there is a vehicle ahead, control to maintain distance from the vehicle ahead, watching its speed.
• The set vehicle speed is displayed on the ICC system indicator in the combination meter.
CHECK FOR INCREASE OF THE CRUISING SPEED
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed increases by 1.6 km /h (1 MPH) as ACCEL/RES switch is pushed.
NOTE:
The maximum set speed of the vehicle-to-vehicl e distance control mode is 144 km/h (89 MPH).
CHECK FOR DECREASE OF THE CRUISING SPEED
1. Set vehicle-to-vehicle distance control mode at desired speed.
2. Check if the set speed decreases by 1.6 km /h (1 MPH) as COAST/SET switch is pushed.
NOTE:
• Vehicle-to-vehicle distance control mode is automatica lly turned off when the driving speed lowers to 32 km/
h (20 MPH) due to the deceleration of the vehicle ahead.
• The minimum set speed of the vehicle-to-vehicle distance control mode is 40 km/h (25 MPH).
CHECK FOR THE CANCELLATION OF VEHICLE-TO-VEHICLE DISTANCE CONTROL MODE (NORMAL DRIV-
ING CONDITION) IN THE FOLLOWING CASES:
1. When the brake pedal is depressed after the system is turned on.
2. When the selector lever is shifted to the "N" (Neutral) position.
3. When the system is turned off.
4. When CANCEL switch is operated.
CHECK FOR RESTORING THE SPEED THAT IS SET BY VEHICLE-TO-VEHICLE DI STANCE CONTROL MODE
BEFORE CANCELLATION
1. Cancel the system by depressing the brake. Then, check that the speed before cancellation is restored
when pressing ACCEL/RES switch with vehi cle speed at 40 km/h (25 MPH) or above.
2. Cancel the system by shifting the selector lever to “N”. Then, check if the speed set before the cancella-
tion is restored when ACCEL/RES switch is pressed.
3. Check if the speed previously set is restored w hen ACCEL/RES switch is operated when driving 40 km/h
(25 MPH) or above, after canceling vehicle-to-v ehicle distance control mode by operating the CANCEL
switch.
CHECK ON/OFF SWITCH OPERATION
1. Start the engine. Then, check that the following operations are performed correctly.
2. Vehicle-to-vehicle distance control mode is displayed when ON/ OFF switch is pressed ON. Vehicle-to-vehicle distance control
mode goes off when ON/OFF switch is turned to OFF.
3. Turn off the ignition switch while ON/OFF switch is ON. Turn the ignition switch back to ON and confirm that CRUISE lamp and
ICC system display are OFF.
CHECK FOR ACCEL/RES, COAST/SET, CANCEL SWITCHES
1. Check if ACCEL/RES, COAST/SET, CANCEL sw itches operate smoothly.
2. Check if switch buttons r ebound as the buttons are released.
CHECK FOR DISTANCE SWITCH
1. Start the engine.
2. Press the ON/OFF switch for less than 1.5 seconds.
3. Press the DISTANCE switch.
4. Check if the set distance indicator changes display in order of:
(long) →(middle)→ (short).

INTELLIGENT KEY UNIT POWER BACK DOOR INPUT SIGNAL
DescriptionINFOID:0000000001539045
Carrying the Intelligent Key, enables the driver to
open the liftgate using the back door switch even when the
vehicle is locked. When pressing the back door switch, the back door switch sends this signal to the Intelligent
Key unit which treats it as a request switch signal. When the Intelligent Key unit, using the rear bumper
antenna, validates the presence of the Intelligent Key, it sends an open signal to the back door control unit
regardless whether the vehicle is locked.
Rear bumper antenna is mounted on the rear bumper and is used to allow the back door handle opening of
the locked back door when the Intelligent Key is present.
