PRECAUTIONS

[POWER DISTRIBUTION SYSTEM]

PRECAUTION

PRECAUTIONS

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

INFOID:0000000009266452

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 Man-

ual.

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

Instruction. 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 Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-

tion 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.

Precaution for Work

INFOID:0000000009266453

• 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 shop 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.

• Follow the steps below to clean components:

- Water soluble dirt:

• Dip a soft cloth into lukewarm water, wring the water out of the cloth and wipe the dirty area.

• Then rub with a soft, dry cloth.

- Oily dirt:

• Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%) and wipe the dirty

area.

• Then dip a cloth into fresh water, wring the water out of the cloth and wipe the detergent off.

• Then rub with a soft, dry cloth.

- Do not use organic solvent such as thinner, benzene, alcohol or gasoline.

- For genuine leather seats, use a genuine leather seat cleaner.
