PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
AHS00019
A
The Supplemental Rest raint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used al ong
with a front seat belt, helps to redu ce th e risk or se verit y of i njury to the driv er and front passenge r for ce rtain
types of collision. This system includes seat belt switch inputs and dual st age front air bag modules. The SRS
system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front
air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted.
Information necessary to service the system safely is included in the SRS and SB section of this Service Manual.
WARNING:
● To avoid rendering the SRS inopera tive, whi ch could incr ease the risk of pe rsonal 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, inc luding incorrect removal and installation of the SRS, can lead to per-
sonal injury ca use d by unintentional ac tiv atio n o f the system. For re mo va l of Spiral Cable and Ai r
Bag Module, see the SRS sec tion.
● Do not use electrical test equ ipment o n any circu it related to the SRS unless in structed 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” Service
● Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
● Before serv ic ing th e S RS , t ur n igni t io n s wit c h OF F, disconnect b oth ba tt e ry ca bl e s an d wai t at l ea st 3 m in -
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.
● Diagnosis sensor unit must always be installed with their arrow marks “⇐” pointing towards the front of the
vehicle for proper operation. Also check diagnos is sensor unit for cr acks, 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 turn steer-
ing wheel and co lumn 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.
● Always replace instrument panel pad following front passenger air bag deployment.

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
Front Seat Belt Pre-Tensioner with Load Limiter AHS0000D
The seat belt pre-tensioner system with lo ad limiter is installed for
both the driver's seat and the front passenger's seat. It operates
simultaneously with the SRS air bag sy stem in the event of a fron tal
collision with an impact exceeding a specified level.
When the frontal collision with an impact exceeding a specified level
occurs, seat belt slack resulting from clothing or other factors is
immediately taken up by the pre-tensioner. Vehicle passengers are
securely restrained.
When passengers in a vehicle are t hrown forward in a collision a nd
the restraining fo rce of the seat belt exceeds a spec ified level, the
load limiter permits the specified extension of the seat belt by the
twisting of the ELR shaft, and a relaxation of the chest-area seat belt

Occupant Classification System AHS000RW
The occupant classification system identifies different size occupants, out of position occupants, and detects if
child seat is present in the fron t passen ger seat. T he occ upant cla ssificati on syste m recei ves inpu ts from the
occupant classification sensor (located inside the passenger seat cushion assembly) and belt tension sensor
(part of the p a sseng er fro nt seat bel t as sembl y an d lo ca te d at th e bel t anc ho r loca tio n). De pend in g on cla ssi fication of passenger, the occupant classificati on system sends a signal to the di ag no sis sensor unit. The diagnosis sensor unit uses this signal to determine full, partial, or non deployment of passenger front air bag in the
event of a collision. Depending on the signal received, the diagnosis sensor unit can disable the passenger
front air bag completely. If this occurs the diagnosis sensor unit will turn on the PASS AIR BAG OFF indicator.
