PRECAUTIONS
PRECAUTIONS PFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
ALS000QG
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 stage 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 ino perative, 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 s ys tem . F or re moval of Spiral C ab le and Air
Bag Module, see the SRS section.
● 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 id entified by yellow and/or orange harnesses or
harness connectors.
