Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000012432103
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 severity 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 NISSAN/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 PrecautionINFOID:0000000012432104
WARNING:
When replacing fuel line parts, be sure to observe the following.
• Put a “CAUTION: FLAMMABLE” sign in the work area.
• Be sure to work in a well ventilated area and have a CO
2 fire extinguisher.
• Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
CAUTION:
• Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosi on-proof container and put the lid on securely. Keep the container in
safe area.
- Release fuel pressure from the fuel lines. Refer to EC-1
37, "Work Procedure" .
- Disconnect the battery ground
cable.
• Always replace O-rings and clamps with new ones.
• Do not kink or twist tubes when they are being installed.
• Do not tighten hose clamps excessi vely to avoid damaging hoses.
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specificati ons are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.

necessary.
• Do not use any tools to disconnected quick connector.
• Keep resin tube (C) away from heat. Be especially careful when welding near the resin tube.
• Prevent acid liquid such as battery electrolyte, etc. from
getting on resin tube.
• Do not bend or twist resin tube during installation and dis- connection.
• Do not remove the remaining retainer (2) on hard tube (or
the equivalent) (A) except when resin tube or retainer is
replaced.
• When resin tube or hard tube (or the equivalent) is
replaced, also replace retainer with new one.
• To keep the connecting portio n clean and to avoid dam-
age and foreign materials, cover them completely with
