PRECAUTIONS
PRECAUTIONS
PFP:00001
Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TEN-
SIONER”
EHS000BD
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.
WAR NIN G:
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 should 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.
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 harness connector.
Precaution for Seat Belt ServiceEHS000BE
CAUTION:
lBefore removing the seat belt pre-tensioner assembly, turn the ignition switch off, disconnect the
battery ground cable 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-ten-
sioner connector, check the system function. Refer toSRS-15, "
SRS Operation Check".
lDo not use 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 seat belt assembly.
AFTER A COLLISION
WAR NIN G:
Inspect all seat belt assemblies including retractors and attaching hardware after any collision.
NISSAN recommends that all seat belt assemblies in use during a collision be replaced unless the col-
lision 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 colli-
sion 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.
