Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951675
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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
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 harn esses can be identified 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 three minutes before performing any service.
Precaution for Draining CoolantINFOID:0000000009460453
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000009460454
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before any removal or disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000009460455
• When instructed to use special service tools, use the s pecified tools. Always be careful to work safely, avoid
forceful operations.
• Use maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or equivalent , if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organi zed way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specified, follow the specifications.
Precaution for Inspection, Repair and ReplacementINFOID:0000000009460456
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.

Assembly
Assembly is in the reverse order of disassembly.
CAUTION:
• Smooth out all wrin kles during assembly.
• Always route side air bag module harness in original location. Replace any deformed or damaged
clips with same type and color. Always install clips in the original location in the harness.
• After work is completed, check that no system ma lfunction is detected causing the air bag warning
lamp to illuminate.
• If a malfunction is detected by the air bag warnin g lamp after repair or replacement of the malfunc-
tion parts, perform the SRS final check. Refer to SRC-17, "SRS Final Check"
.
• When installing the seat cushion trim, firmly push down while slid-
ing your hand along the seams as shown ( ) to ensure the hook
fasteners below the seat cushion trim are fastened properly.
• Install new hog rings on the seat cushion trim in original positions. Use only one hog ring in each designated location.
Ensure hog rings are correctly fastened around both the seat cush-
ion trim and seat cushion pad wires.

DRIVER SIDE : Side air bag moduleINFOID:0000000009462950
WARNING:
Do not leave any objects (screwdrivers, tools, etc. ) on the seat during seatback repair. It can lead to
personal injury if the side ai r bag should accidentally deploy.
CAUTION:
• Before servicing, turn ignition sw itch OFF, disconnect both battery terminals and wait at least three
minutes.
• Handle the side air bag module carefully. During disassembly, alw ays hold the side air bag module,
do not let it hang by the wire harness.
• Always work from the side or back of the seat back assembly, do not work in front of seat.
• Do not use air tools or electric tools for servicing the seat assembly.
• Replace the side air bag module if it h as been dropped or sustained an impact.
• Do not insert any objects into the side air bag module.
• Do not attempt to disassemble the side air bag module.
• Do not expose the side air bag module to temperatures exceeding 93 °C (200 °F).
• Do not expose the side air bag module to any oil, grease, detergent or water.
• During disassembly, do not damage the seatback board, chutes, connectors, retainers, clips, module
harness or the side air bag module.
NOTE:

INFOID:0000000009461088
NISSAN VEHICLE IMMOBILIZER SYST EM-NATS : System DescriptionINFOID:0000000009461089
SYSTEM DESCRIPTION
• The NISSAN VEHICLE IMMOBILIZER SYSTEM-NATS [NVIS (NATS)] prevents the engine from being
started by Intelligent Key whose ID is not registered to the vehicle (BCM). It has higher protection against
auto theft involving the duplication of mechanical keys.
• The ignition key integrated in the Intelligent Key c annot start the engine. When the Intelligent Key battery is
discharged, the NVIS (NATS) ID verification is per formed between the transponder integrated with Intelligent
Key and BCM via NATS antenna amp. when the Intelligent Key backside is contacted to push-button ignition
switch. If the verification results are OK, the engine start operation can be performed by the push-button igni-
tion switch operation.
• Locate the security indicator lamp and apply the anti-t heft system equipment sticker that warns that the NVIS
(NATS) is on-board the model.
• Security indicator lamp always blinks when the pow er supply position is any position other than ON.
• Up to 4 Intelligent Keys can be registered (includi ng the standard ignition key) upon request from the owner.
• Specified registration is required when replacing ECM, BCM or Intelligent Key.
• Possible symptom of NVIS (NATS) malfunction is “Engine cannot start”. The engine can not be started
because of other than NVIS (NATS) malfunction, so start the trouble diagnosis according to SEC-63, "Work
Flow".
• If ECM other than genuine part is installed, the engi ne cannot be started. For ECM replacement procedure,
refer to EC-540, "Removal and Installation"
(with QR25DE) EC-997, "Removal and Installation" (with
VQ35DE).
