    PRECAUTIONS

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

    INFOID:0000000009267342

    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.

    Service Notice and Precautions for EPS System

    INFOID:0000000009267343

    • Check the following item when performing the trouble diagnosis.

    - Check any possible causes by interviewing the symptom and it

    ′s condition from the customer if any malfunc-

    tion, such as EPS warning lamp is turned ON, occurs.

    - Check if air pressure and size of tires are proper, the specified part is used for the steering wheel, and con-

    trol unit is genuine part.

    - Check if the connection of steering column assembly and steering gear assembly is proper (there is not

    looseness of bolts, damage of rods, boots or sealants, and leakage of grease, etc.).

    - Check if the wheel alignment is adjusted properly.

    - Check if there is any damage or modification to suspension or body resulting in increased weight or altered

    ground clearance.

    - Check if installation conditions of each link and suspension are proper.

    - Check if the battery voltage is proper.

    - Check connection conditions of each connector are proper.

    - Before connecting or disconnecting the EPS control unit harness

    connector, turn ignition switch “OFF” and disconnect battery

    ground cable. Because battery voltage is applied to EPS control

    unit even if ignition switch is turned “OFF”.

    STC-4

    < PRECAUTION >

    PRECAUTIONS

    - When connecting or disconnecting pin connectors into or from

    EPS control unit, take care not to damage pin terminals (bend or

    break).

    - When connecting pin connectors, make sure that there are no

    bends or breaks on EPS control unit pin terminal.

    • During quick steering, rasping noise may be heard from around the

    steering wheel. This is not a malfunction. The noise is an operating

    noise of the EPS system under normal conditions. If the rasping

    noise occurs during slow steering, this may not be an operating

    noise of the system. In this case, it is necessary to find out the

    location of the noise and repair, if necessary.
