Nissan Maxima Service and Repair Manual: Precaution
PRECAUTIONS
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 three
minutes before performing any service.
Precaution for Work

or deform it. If a component may be subject to interference, be sure to
protect it with a shop cloth.

similar tool, be sure to wrap the component with a shop cloth or vinyl
tape to protect it.
- Protect the removed parts with a shop cloth and prevent them from
