Service Notice
lWhen removing or installing various parts, place a cloth or padding onto the vehicle body to prevent
scratches.
lHandle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to soil
or damage them.
lApply sealing compound where necessary when installing parts.
lWhen applying sealing compound, be careful that the sealing compound does not protrude from parts.
lWhen replacing any metal parts (for example body outer panel, members, etc.), be sure to take rust
prevention measures.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System ªAir Bagº and ªSeat Belt Pre-tensionerº, 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
Supplemental Restraint System consists of air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-tensioners, a diagnosis sensor unit, warning
lamp, wiring harness and spiral cable. Information necessary to service the system safely is included in the
RS sectionof the Service Manual.
If the vehicle is equipped with side air bag as the Supplemental Restraint System, the side air bag used along
with the seat belt helps to reduce the risk or severity of injury to the driver and front passenger in a side
collision. The side air bag consists of air bag modules (located in the outer side of front seats), satellite
sensor, diagnosis sensor unit (which is one of components of air bags for a frontal collision), wiring harness,
warning lamp (which is one of components of air bags for a frontal collision).
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 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 do so
in this Service Manual. SRS wiring harnesses are covered with yellow insulation (either just
before the harness connectors or for the complete harness) for easy identification.
PRECAUTIONS

lWhen removing or installing seats with side air bag module, be sure to disconnect or connect side air
