Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
(Dual Air Bag System)
The Supplemental Restraint System ªAir Bagº and ªSeat Belt Pre-tensionerº, used along with a seat belt, help
to reduce the risk or severity of injury to the driver and front passenger in a frontal collision. The Supplemen-
tal 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, wir-
ing harness and spiral cable.
WARNING:
ITo 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.
IImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
IDo 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 for Steering System
IBefore disassembly, thoroughly clean the outside of the unit.
IDisassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
IWhen disassembling parts, be sure to place them in order on a part rack so they can be reinstalled
in their proper positions.
IUse nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
IBefore inspection or reassembly, carefully clean all parts with a general purpose, non-flammable
solvent.
IBefore assembly, apply a coat of recommended ATF* to hydraulic parts. Vaseline may be applied
to O-rings and seals. Do not use any grease.
IReplace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.
