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 3
minutes before performing any service.
Precautions for Drive Shaft
Observe the following precautions when disassembling and assembling drive
shaft.
- Joint sub-assembly does not disassemble because it is non-overhaul
parts.
- Perform work in a location which is as dust-free as possible.
- Before disassembling and assembling, clean the outside of parts.
- Prevention of the entry of foreign objects must be taken into
account during disassembly of the service location.
- Disassembled parts must be carefully reassembled in the correct
order. If work is interrupted, a clean cover must be placed over parts.
- Paper shop cloths must be used. Fabric shop cloths must not be
used because of the danger of lint adhering to parts.
- Disassembled parts (except for rubber parts) should be cleaned
with kerosene which shall be removed by blowing with air or wiping with
paper shop cloths.
