Nissan Maxima Service and Repair Manual: Precaution

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"

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. 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 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 harness
    connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

  • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Ignition
    ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a
    hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing
    serious injury.
  • When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the
    battery, and wait at least 3 minutes before performing any service.
