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.
Service Notice or Precautions
- In case of removing steering gear assembly, make the final tightening
with grounded and unloaded vehicle condition, and then check wheel
alignment.
- Observe the following precautions when disassembling.
- Before disassembly, thoroughly clean the outside of the unit.
- Disassembly should be done in a clean work area. It is important
to prevent the internal parts from becoming contaminated by dirt or other
foreign matter.
- For easier and proper assembly, place disassembled parts in order
on a parts rack.
- Use nylon cloth or paper towels to clean the parts; common shop
rags can leave lint that might interfere with their operation.
- Do not reuse non-reusable parts.
- Before assembling, apply the specified grease to the directed
parts.
