PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EHS0026D
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo 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 inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Seat Belt ServiceEHS00265
CAUTION:
lBefore removing the seat belt pre-tensioner assembly, turn the ignition switch OFF, disconnect
both battery cables and wait at least 3 minutes.
lDo not use electrical test equipment for seat belt pre-tensioner connector.
lAfter replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-
tensioner assembly connector, ensure entire SRS operates properly. Refer toSRS-18, "
SRS Oper-
ation Check".
lDeploy seat belt pre-tensioner assembly before disposing. Refer toSRS-49, "DISPOSAL OF AIR
BAG MODULE AND SEAT BELT PRE-TENSIONER".
lDo not disassemble buckle or seat belt assembly.
lReplace anchor bolts if they are deformed or worn out.
lNever oil tongue and buckle.
lIf any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
lIf webbing is cut, frayed, or damaged, replace seat belt assembly.
lWhen replacing seat belt assembly, use a genuine NISSAN seat belt assembly.
AFTER A COLLISION
WARNING:
lInspect all seat belt assemblies including retractors and attaching hardware after any collision.
lNISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the
collision was minor and the belts show no damage and continue to operate properly. Failure to do
so could result in serious personal injury in an accident. Seat belt assemblies not in use during a
collision should also be replaced if either damage or improper operation is noted. Seat belt pre-
tensioner should be replaced even if the seat belts are not in use during a frontal collision in which
the air bags are deployed.
Replace any seat belt assembly (including anchor bolts) if:
lThe seat belt was in use at the time of a collision (except for minor collisions and the belts, retractors and
buckles show no damage and continue to operate properly).
lThe seat belt was damaged in an accident. (i.e., torn webbing, bent retractor or guide, etc.)
lThe seat belt attaching point was damaged in an accident. Inspect the seat belt attaching area for damage
or distortion and repair as necessary before installing a new seat belt assembly.
lAnchor bolts are deformed or worn out.
lThe seat belt pre-tensioner should be replaced even if the seat belts are not in use during the collision in
which the air bags are deployed.

CAUTION:
lFor installing/removing seat belt pre-tensioner connector,
insert a thin screwdriver wrapped in tape into the notch, lift
the lock and remove the connector.
lInstall the connector with the lock raised, and push the lock
into the connector.
INSTALLATION OF SEAT BELT RETRACTOR
Installation is in the reverse order of removal.
