Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.                                                                                     B
Precautions for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT
BELT PRE-TENSIONER"                                                                                           EAS001KM
                                                                                                                          C
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               D
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 and SB section of this Service Man-
ual.                                                                                                                      E
WARNING:
G    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 per-                    F
     formed by an authorized NISSAN/INFINITI dealer.
G    Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
     sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
                                                                                                                         G
     Bag Module, see the SRS section.
G    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
     harness connectors.                                                                                                  H

Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM -

NVIS/IVIS (NATS) will immobilize the engine if someone tries to start it without the registered key of NVIS/IVIS
(NATS).
Both of the originally supplied ignition key IDs have been NVIS/IVIS (NATS) registered.                                   J
The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is
functioning.
Therefore, NVIS/IVIS (NATS) warns outsiders that the vehicle is equipped with the anti-theft system.

     "ON" position.
     This lighting up indicates that the anti-theft is not functioning, so prompt service is required.
                                                                                                                          L
G    When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
     other NVIS/IVIS (NATS) ignition key IDs), CONSULT-II hardware and CONSULT-II NVIS/IVIS (NATS)
     software is necessary.
     Regarding the procedures of NVIS/IVIS (NATS) initialization and NVIS/IVIS (NATS) ignition key ID regis-             M
     tration, refer to CONSULT-II operation manual, NVIS/IVIS (NATS).
Therefore, CONSULT-II NVIS/IVIS (NATS) software (program card and operation manual) must be kept
strictly confidential to maintain the integrity of the anti-theft function.
G    When servicing NVIS/IVIS (NATS) (trouble diagnoses, system initialization and additional registration of
     other NVIS/IVIS (NATS) ignition key IDs), it may be necessary to re-register original key identification.
     Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be regis-
     tered into NVIS/IVIS (NATS).
G    When failing to start the engine first time using the key of NVIS/IVIS (NATS), start as follows.
1. Leave the ignition key in "ON" position for approximately 5 seconds.
2. Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while keeping the key separate from any others on key-chain.

G   Do not operate the engine for an extended period of time without
    proper exhaust ventilation.
    Keep the work area well ventilated and free of any flammable
    materials. Special care should be taken when handling any flam-
    mable or poisonous materials, such as gasoline, refrigerant gas,
    etc. When working in a pit or other enclosed area, be sure to
    properly ventilate the area before working with hazardous mate-
    rials.
    Do not smoke while working on the vehicle.

                                                                                                         SGI285




G   Before jacking up the vehicle, apply wheel chocks or other tire
    blocks to the wheels to prevent the vehicle from moving. After
    jacking up the vehicle, support the vehicle weight with safety
    stands at the points designated for proper lifting before working
    on the vehicle.
    These operations should be done on a level surface.
G   When removing a heavy component such as the engine or tran-
    saxle/transmission, be careful not to lose your balance and drop
    them. Also, do not allow them to strike adjacent parts, especially
    the brake tubes and master cylinder.
                                                                                                         SGI231




G   Before starting repairs which do not require battery power:
    Turn off ignition switch.
    Disconnect the negative battery terminal.
G   If the battery terminals are disconnected, recorded memory of
    radio and each control unit is erased.

    Avoid contact with hot metal parts.
    Do not remove the radiator cap when the engine is hot.
G   Dispose of or recycle drained oil or the solvent used for cleaning
    parts in an appropriate manner.
G   Do not attempt to top off the fuel tank after the fuel pump nozzle
    shuts off automatically.
    Continued refueling may cause fuel overflow, resulting in fuel
    spray and possibly a fire.
G   Clean all disassembled parts in the designated liquid or solvent
    prior to inspection or assembly.                                                                      SGI233


G   Replace oil seals, gaskets, packings, O-rings, locking washers, cotter pins, self-locking nuts, etc. with new
    ones.
G   Replace inner and outer races of tapered roller bearings and needle bearings as a set.
G   Arrange the disassembled parts in accordance with their assembled locations and sequence.
G   Do not touch the terminals of electrical components which use microcomputers (such as ECM).
    Static electricity may damage internal electronic components.
G   After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.
G   Use only the fluids and lubricants specified in this manual.

WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)                         I
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
                                                                                                                        J
Precautions for Three Way Catalyst                                                                          EAS001KO


If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
                                                                                                                        K
G     Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
G     When checking for ignition spark or measuring engine compression, make tests quickly and only when
      necessary.                                                                                                        L
G     Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
      the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three             M
way catalyst.
Precautions for Fuel (Unleaded Gasoline Recommended)                                                        EAS001Z5


Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91). E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) may only be used in vehicles specif-
ically designed for E-85 fuel (i.e. Flexible Fuel Vehicles - FFV models).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.

    the multiport fuel injection system or ECM:
    Turn ignition switch to "OFF" position.
    Disconnect negative battery terminal.
    Otherwise, there may be damage to ECM.
G   Before disconnecting pressurized fuel line from fuel pump to
    injectors, be sure to release fuel pressure.
G   Be careful not to jar components such as ECM and mass air
    flow sensor.

                                                                            SGI787


Precautions for Hoses                                                          EAS001KR

HOSE REMOVAL AND INSTALLATION
G   To prevent damage to rubber hose, do not pry off rubber hose
    with tapered tool or screwdriver.




                                                                            SMA019D



G   To reinstall the rubber hose securely, make sure of hose inser-
    tion length and clamp orientation. (If tube is equipped with hose
    stopper, insert rubber hose into tube until it butts up against
    hose stopper.)




                                                                            SMA020D


HOSE CLAMPING
G   If old rubber hose is re-used, install hose clamp in its original
    position (at the indentation where the old clamp was). If there is
    a trace of tube bulging left on the old rubber hose, align rubber
    hose at that position.




                                                                            SMA021D

G   A line with regular weight (wider line) represents a "detectable
    line for DTC (Diagnostic Trouble Code)". A "detectable line for                        GI
    DTC" is a circuit in which ECM can detect its malfunctions with
    the on board diagnostic system.
G   A line with less weight (thinner line) represents a "non-detect-                        B
    able line for DTC". A "non-detectable line for DTC" is a circuit in
    which ECM cannot detect its malfunctions with the on board
    diagnostic system.

HOW TO PROBE CONNECTORS
Connector damage and an intermittent connection can result from improperly probing of the connector during            I
circuit checks.
The probe of a digital multimeter (DMM) may not correctly fit the connector cavity. To correctly probe the con-
nector, follow the procedures below using a "T" pin. For the best contact grasp the "T" pin using an alligator
clip.                                                                                                                 J

Probing from Harness Side
Standard type (not waterproof type) connector should be probed                                                        K
from harness side with "T" pin.
G   If the connector has a rear cover such as a ECM connector,
    remove the rear cover before probing the terminal.
                                                                                                                      L
G   Do not probe waterproof connector from harness side. Damage
    to the seal between wire and connector may result.
