Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EIS00DZ8
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 SRS and SB section of
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/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo 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
harness connectors.
Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” ServiceEIS00DZ4
lDo not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
lBefore 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.
lThe air bag diagnosis sensor unit must always be installed with the arrow marks “Ü” pointing toward the
front of the vehicle for proper operation. Also check the air bag diagnosis sensor unit for cracks, deformi-
ties or rust before installation and replace as required.
lThe 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.
lHandle 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.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
lAfter air bag inflates, the front instrument panel assembly should be replaced if damaged.
