PRECAUTIONS

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT 
PRE-TENSIONER"

INFOID:0000000006237842

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 “SRS AIR BAG” and “SEAT BELT” 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 that 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 “SRS AIR BAG”.

• 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 har-
ness connectors.

PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS

WARNING:

• When working near the Air Bag Diagnosis Sensor Unit or other Air Bag 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

INFOID:0000000006217352

• When removing or installing various parts, place a cloth or padding onto the vehicle body to prevent

scratches.

• Handle trim, molding, instruments, grille, etc. carefully during removing or installing. Be careful not to oil or

damage them.

• Apply sealing compound where necessary when installing parts.
• When applying sealing compound, be careful that the sealing compound never protrudes from parts.
• When replacing any metal parts (for example body outer panel, members, etc.), always take rust prevention

measures.

Precaution for Work

INFOID:0000000006217353

• When removing or disassembling each component, be careful not to damage or deform it. If a component

may be subject to interference, always protect it with a shop cloth.

• When removing (disengaging) components with a screwdriver or similar tool, always wrap the component

with a shop cloth or vinyl tape to protect it.

• Protect the removed parts with a shop cloth and keep them.
• Replace a deformed or damaged clip.
• If a part is specified as a non-reusable part, always replace it with new one.
• Always tighten bolts and nuts securely to the specified torque.
• After reinstallation is complete, always check that each part works normally.
• Follow the steps below to clean components.
- Water soluble foul: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the

fouled area.
Then rub with a soft and dry cloth.

a soft and dry cloth.

• Never use organic solvent such as thinner, benzene, alcohol, and gasoline.
