Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS composition which is available to NISSAN MODEL Y61 is as follows (The composition varies
according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
PRECAUTION
RS-1

CAUTION:
+Before removing the seat belt pre-tensioner assembly (if equipped), turn the ignition switch off,
disconnect both battery cables and wait at least 3 minutes.
+After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to ``SRS Operation Check'' (RS-30) for details.
+Do not disassemble buckle or seat belt assembly.
+Replace anchor bolts if they are deformed or worn out.
+Never oil tongue and buckle.
+If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
+If webbing is cut, frayed, or damaged, replace seat belt assembly.
+When replacing seat belt assembly, use a genuine seat belt assembly.
+After any collision, inspect all seat belt assemblies, including retractors and other attached hard-
wares (i.e., guide rail set).

Precautions for SRS ``AIR BAG'' and ``Seat Belt
Pre-tensioner'' Service
+Do not use a circuit tester to check SRS circuits unless instructed to in this Service Manual.
+Before servicing the SRS, turn ignition switch ``OFF'', disconnect both battery cables and wait for at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt
pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes
have passed.
+Diagnosis sensor unit must always be installed with their arrow marks ``
S'' pointing towards the front of
the vehicle for proper operation. Also check diagnosis sensor unit for cracks, deformities or rust before
installation and replace as required.
+The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
+Handle air bag module carefully. Always place it with the pad side facing upward.
+Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
+Instrument panel assembly should be replaced after air bag in¯ates if damaged.
