Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000001702325
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. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
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/INFINITI dealer.
 Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal
injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag
Module, see the SR section.
 Do 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 and/or orange harnesses or har-
ness connectors.
Precaution for SRS "AIR BAG" and "SEAT BELT PRE-TENSIONER" Service
INFOID:0000000001702326
 Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
 Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 min-
utes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-
tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have
passed.
 The air bag diagnosis sensor unit must always be installed with the arrow mark “⇐” pointing toward the front
of the vehicle for proper operation. Also check air bag diagnosis sensor unit for cracks, deformities or rust
before installation and replace as required.
 The spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt to
turn steering wheel or column after removal of steering gear.
 Handle air bag module carefully. Always place driver and front passenger air bag modules with the pad side
facing upward and seat mounted front side air bag module standing with the stud bolt side facing down.
 Conduct self-diagnosis to check entire SRS for proper function after replacing any components.
 After air bag inflates, the front instrument panel assembly should be replaced if damaged.
