Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000005848468
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. This system includes seat belt switch inputs and dual stage front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and w hether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SR and SB section of this Service Man-
ual.
WARNING:
• To avoid rendering the SRS inopera tive, which could increase the risk of personal injury or death in
the event of a collision which would result in air bag inflation, all maintenance must be performed by
an authorized NISS AN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
 Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identi fied by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
 When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
 When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery, and wait at least 3 minu tes before performing any service.
Precaution Necessary for Steering W heel Rotation After Battery Disconnect
INFOID:0000000005851835
NOTE:
 This Procedure is applied only to models with Intelli gent Key system and NATS (NISSAN ANTI-THEFT SYS-
TEM).
 Remove and install all control units after disconnecting both battery cables with the ignition knob in the
″LOCK ″ position.
 Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.
If DTC is detected, perform trouble diagnosis according to self-diagnostic results.
For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
anism is adopted on the key cylinder.
For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
steering wheel rotation will become impossible.
If steering wheel rotation is required when battery pow er is interrupted, follow the procedure below before
starting the repair operation.
OPERATION PROCEDURE
1. Connect both battery cables. NOTE:
Supply power using jumper cables if battery is discharged.
2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC ″ position. At this time, the
steering lock will be released.
3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
rotated.
4. Perform the necessary repair operation.

5. When the repair work is completed, return the ignition switch to the ″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for WorkINFOID:0000000003775660
 When removing or disassembling each component, be ca reful not to damage or deform it. If a component
may be subject to interference, be sure to protect it with a shop cloth.
 When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component
with a shop cloth or vinyl tape to protect it.
 Protect the removed parts with a shop cloth and keep them.
 Replace a deformed or damaged clip.
 If a part is specified as a non-reusable part, always replace it with new one.
 Be sure to tighten bolts and nuts securely to the specified torque.
 After re-installation is completed, be sure to check that each part works normally.
 Follow the steps below to clean components.
- Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the fouled area.
Then rub with a soft and dry cloth.
- Oily foul: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe
the fouled area.
Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub with
a soft and dry cloth.
 Do not use organic solvent such as thinner, benzene, alcohol, or gasoline.
 For genuine leather seats, use a genuine leather seat cleaner.

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.

XM SAT SUBSCRIPTION STATUS
The XM NavTraffic subscription status can be checked.
Error History
The self-diagnosis results are judged depending on whether any
error occurs from when “Self-diagnosis” is selected until the self-
diagnosis results are displayed.
However, the diagnosis results are judged normal if an error has
occurred before the ignition SW is turned ON and then no error has
occurred until the self-diagnosis start. Check the “Error History” to
detect any error that may have occurred before the self-diagnosis
start because of this situation.
Count up method A
• The counter resets to 0 if an error occurs when IGN switch is
turned ON. The counter increases by 1 if thecondition is normal at
a next IGN ON cycle.
• The counter upper limit is 39. Any counts exceeding 39 are ignored. The counter can be reset (no error- record display) with the “Delete log” switch or CONSULT-III.
Count up method B
• The counter increases by 1 if an error occurs when IGN switch is ON. The counter will not decrease even
ifthe condition is normal at the next IGN ON cycle.
• The counter upper limit is 50. Any counts exceeding 50 are ignored. The counter can be reset (no error- record display) with the “Delete log” switch or CONSULT-III.
