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

    INFOID:0000000003939383

    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

    Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har-
    ness connectors.

    Precaution Necessary for Steering Wheel Rotation After Battery Disconnect

    INFOID:0000000004448905

    NOTE:
    • This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS-

    TEM).

    • Remove and install all control units after disconnecting both battery cables with the ignition knob in the

    ″

    LOCK

    ″

    position.

    • Always use CONSULT-III to perform self-diagnosis as a part of each function inspection after finishing work.

    If DTC is detected, perform trouble diagnosis according to self-diagnostic results.

    For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech-
    anism is adopted on the key cylinder.
    For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and
    steering wheel rotation will become impossible.
    If steering wheel rotation is required when battery power is interrupted, follow the procedure below before
    starting the repair operation.

    OPERATION PROCEDURE

    1.

    Connect both battery cables.
    NOTE:
    Supply power using jumper cables if battery is discharged.

    2.

    Use the Intelligent Key or mechanical key to turn the ignition switch to the

    ″

    ACC

    ″

    position. At this time, the

    steering lock will be released.

    3.

    Disconnect both battery cables. The steering lock will remain released and the steering wheel can be
    rotated.

    4.

    Perform the necessary repair operation.

    5.

    When the repair work is completed, return the ignition switch to the

    ″

    LOCK

    ″

    position before connecting

    the battery cables. (At this time, the steering lock mechanism will engage.)

    6.

    Perform a self-diagnosis check of all control units using CONSULT-III.
