PRECAUTIONS
Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951707
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. 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 inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness 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 Igni-
tion ON or engine running, DO NOT use air or electri c 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.
General PrecautionsINFOID:0000000009464451
• When installing rubber bushings, the final tightening mu st be carried out under unladen conditions with tires
on ground. Oil might shorten the life of rubber bushings. Be sure to wipe off any spilled oil.
- Unladen conditions mean that fuel, engine coolant and lubricant are full. Spare tire, jack, hand tools and mats are in designated positions.
• After servicing suspension parts, be sure to check wheel alignment.
• Self-lock nuts are not reusable. Always use new ones when installing. Since new self-lock nuts are pre-oiled,
tighten as they are.

• 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 Seat Belt ServiceINFOID:0000000009462957
CAUTION:
• Before removing the seat belt pre-tensioner assembl y, turn the ignition switch OFF, disconnect both
battery terminals and wait at least three minutes. For approximately three minutes after the battery
terminals have been removed, it is still possible for the air bag and seat belt pre-tensioner to deploy.
Therefore, do not attempt work on any SRS conn ectors or wires until at least three minutes have
passed.
• After replacing or reinstalling seat belt pre -tensioner assembly or reconnecting seat belt pre-ten-
sioner assembly connector, make sure entire SRS operates properly. Refer to SRC-15, "SRS Opera-
tion Check".
• Do not disassemble buckle or seat belt assembly.
• Replace anchor bolts if th ey are deformed or worn out.
• Do not oil tongue or buckle.
• If any component of seat belt assembly is questionable, do not re pair. Replace the whole seat belt
assembly.
• If webbing is cut, frayed or damaged, replace seat belt assembly.
• When replacing seat belt assembly, use a genuine NISSAN seat belt assembly.
Precaution for WorkINFOID:0000000009462958
• When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth.
• When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it.
• Protect the removed parts with a s hop cloth and prevent them from being dropped.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with a new one.
• Be sure to tighten bolts and nuts securely to the specified torque.
• After installation is complete, be sure to check that each part works properly.
