PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001612877
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 whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the “SUPPLEMENTAL RESTRAINT SYS-
TEM” and “SEAT BELTS” of this Service Manual.
WARNING:
• To avoid rendering the SRS inoper ative, 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 NISSAN/INFINITI dealer.
 Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintentional act ivation of the system. For removal of Spiral Cable and Air Bag
Module, see the “SUPPLEMEN TAL RESTRAINT SYSTEM”.
 Do not use electrical test equipm ent 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.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000001327741
 Do not use electrical test equipment to check SRS ci rcuits unless instructed to in this Service Manual.
 Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are remov ed, it is still possible for the air bag and seat belt pre-
tensioner to deploy. Therefore, do not work on any SR S connectors or wires until at least 3 minutes have
passed.
 Diagnosis sensor unit must always be installed with their arrow marks “ ⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before installa-
tion and replace as required.
 The spiral cable must be aligned with the neutral position since its rotations are limited. Do not turn steering
wheel and column after removal of steering gear.
 Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
 Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
 After air bag inflates, the front instrument panel assembly should be replaced if damaged.
 Always replace instrument panel pad following front passenger air bag deployment.
 Disposal, recycling, and transportation of air bag m odules and seat belt pre-tensioners should be performed
in compliance with applicable federal, state and local laws and regulations.
Occupant Classification System PrecautionINFOID:0000000001327742
Replace occupant classification system control uni t and passenger front seat cushion as an assembly.
Refer to Refer to Service Manual .

 Always place driver air bag module with pad side facing upward.
 Do not insert any foreign objects (screwdriver, etc.) into driv-
erair bag module.
 Do not disassemble driver air bag module.
 Do not use old bolts after removal; replace with new bolts.
 Do not expose the driver air bag module to temperatures exceeding90 °C (194 °F).
 Replace driver air bag module if it has been dropped or sus-
tainedan impact.
 Do not allow oil, grease or water to come in contact with the
driver air bag module.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
 Fix the air bag module harness (shown as A in the figure) to
the harness fixing hook (s hown as B in the figure).
 Be careful not to damage the harness while installing.
 Tighten the special bolts after exactly adjusting the centers of fi xing holes on the air bag module
side and the steering wheel side. If the holes are misaligned, the bolt threads are damaged and the
module is not installed securely.
 After the work is completed, make sure no system malfunction is detected by air bag warning lamp.
 In case that malfunction is detected by the air ba g warning lamp, reset by the self-diagnosis function
and delete the memory by CONSOULT–III.
 In case that malunction is still detected after th e above operation, peform self-diagnosis to repair
malfunctions. Refer to Refer to SRS-23, "

 The neutral position is set as follows. Turn quietly the spiral cable clockwise to the end position.
Then turn it counterclockwise (about 2 and half turns) and
stop turning at the point on which the stopper insertion holes
are in the same position.
The service part is installed in the neutral position by the
stopper and can be set without adjusting after the stopper is
removed.
 Do not turn the spiral cable r ashly and also beyond the limit
number of turns. (These will cause cable snap.)
 Adjust the spiral cable locating pin (showed as A inthe figure) to the steering wheel locating pin hole (showed as C in the
figuer).
 Secure the air bag harness wi th the harness fixing hook.
 After the work is completed, make sure no system malfunc- tion is detected by air bag warning lamp.
 In case that malfunction is detected by the air bag warning lamp, reset by the self-diagnosis function and delete the
