Just been looking at it in the manual, it says this about it..
PRECAUTIONS
Supplemental Restraint System (SRS) “AIR
BAG” and “SEAT BELT PRE-TENSIONER”
(Dual Air Bag System)
The Supplemental Restraint System “Air Bag” and “Seat Belt Pre-tensioner”, 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 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.
WARNING:
.
To 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 performed
by an authorized NISSAN dealer.
.
Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system.
.
Do 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.
