Precaution for Supplemental Restraint Syst
em (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951692
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.

Removal and Installation
INFOID:0000000009460685
WARNING:
• Perform the procedure with the exhaust system fu lly cooled down because the system will be hot
just after the engine is turned off.
• Be careful not to cut your hand on the insulator edges.
CAUTION:
• Use Genuine NISSAN exhaust system parts or equival ent, which are specifically designed for heat
resistance, corrosion resistance, and shape.
REMOVAL
Remove exhaust system components using power tool.
• Remove heated oxygen sensor using Tool as needed.
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
• Always replace exhaust gaskets with new ones when reassembling.
• Before installing a new heated oxygen sensor, cl ean and lube the exhaust tube threads using suit-
able tool.
• Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7
in) onto a hard surface such as a co ncrete floor; install a new one.
• Do not over-tighten the heated oxygen sensor. Doing so may damage the heated oxygen sensor,
resulting in the MIL coming on.
• If any mounting insulator is badly deformed, repair or replace it. If deposits such as mud pile up on
the mounting insulator, clean and inspect them.
• When installing the insulator avoid large gaps or interference between the insulator and each
exhaust pipe.
• Remove deposits from the sealing surface of each connection. Connect them securely to avoid
exhaust gas leaks.
• Temporarily tighten the exhaust manifold side nuts and the vehicle side bolts. Check each part for
any interference, and then tighten th e nuts and bolts to specification.
• When installing each mounting rubber, avoid twisting or excessive extension in up/down and right/
left directions.
• Tighten the bolts without causi ng interference with the flange.
Inspection After InstallationINFOID:0000000009460686
• With the engine running, check the exhaust tube joints for exhaust gas leaks and abnormal noise.
• Check that the mounting brackets and mounting insulators are installed properly and free from excessive stress. Improper installation could result in excessive noise, leaks, and vibration.
