Supplemental Restraint System (SRS) ``AIR
BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of air bag
module (located in the center of the steering wheel), diagnosis sensor unit, warning lamp, wiring harness
and spiral cable. Information necessary to service the system safely is included in theRS sectionof 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 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 are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.
