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"                                                                                          AAS000EW
                                                                                                                          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:
q    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.
q    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.
q    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

                                                                                                                          I
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.
                                                                                                                          K
q    When NVIS/IVIS (NATS) detects trouble, the security indicator lamp lights up while ignition switch is in
     "ON" position.
     This lighting up indicates that the anti-theft is not functioning, so prompt service is required.
                                                                                                                          L
q    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.
q    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).
q    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.

Precautions Necessary for Steering Wheel Rotation After Battery Disconnect
                                                                                                             AAS000L1

NOTE:
q    This Procedure is applied only to models with Intelligent Key system and NVIS/IVIS (NISSAN/INFINITI
     VEHICLE IMMOBILIZER SYSTEM - NATS).
q    Remove and install all control units after disconnecting both battery cables with the ignition knob in the
     LOCK position.
q    Always use CONSULT-II 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 NVIS/IVIS, an electrically controlled steering lock
mechanism 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-II.
Precautions for Procedures without Cowl Top Cover                                                           AAS000W0


When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.

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)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for Three Way Catalyst                                                                          AAS000EZ


If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
q     Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
q     When checking for ignition spark or measuring engine compression, make tests quickly and only when
      necessary.
q     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
way catalyst.
Precautions for Fuel (Unleaded Premium Gasoline Recommended)                                                AAS000F0


Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research
octane number 91).

For improved vehicle performance, NISSAN/INFINITI recommend the use of unleaded premium gasoline with
an octane rating of at least 91 AKI number (Research octane number 96).

CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.

Precautions for Engine Oils                                                                                   AAS000F3


Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
q   Avoid prolonged and repeated contact with oils, particularly used engine oils.
q   Wear protective clothing, including impervious gloves where practicable.
q   Do not put oily rags in pockets.
q   Avoid contaminating clothes, particularly underpants, with oil.
q   Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-
    larly.
q   First aid treatment should be obtained immediately for open cuts and wounds.
q   Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
q   Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepa-
    rations containing lanolin replace the natural skin oils which have been removed.
q   Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
q   If skin disorders develop, obtain medical advice without delay.
q   Where practical, degrease components prior to handling.
q   Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
    shields; in addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning pollution vary between regions.
