Description

INFOID:0000000005272990

Observe the following precautions to ensure safe and proper servicing. These precautions are not
described in each individual section.

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

INFOID:0000000005522974

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.

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 NATS (NISSAN ANTI-THEFT SYSTEM)

INFOID:0000000005272992

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

• When servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS igni-

tion key IDs), CONSULT-III hardware and CONSULT-III NATS software is necessary.
Regarding the procedures of NATS initialization and NATS ignition key ID registration, refer to CONSULT-III
operation manual, NATS.

Therefore, CONSULT-III NATS software (program card and operation manual) must be kept strictly
confidential to maintain the integrity of the anti-theft function.
• When servicing NATS (trouble diagnoses, system initialization and additional registration of other NATS igni-

tion 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 registered into NATS.

• When failing to start the engine first time using the key of NATS, start as follows.
1.

Leave the ignition key in "ON" position for approximately 5 seconds.

Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.

< PRECAUTION >

PRECAUTIONS

Repeat step 1 and 2 again.

Restart the engine while keeping the key separate from any others on key-chain.

General Precaution

INFOID:0000000005272993

• 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 inflammable
materials. Special care should be taken when handling any inflam-
mable or poisonous materials, such as gasoline, refrigerant gas,
etc. When working in a pit or other enclosed area, be sure to prop-
erly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.

• Before jacking up the vehicle, apply wheel chocks or other tire

blocks to the wheels to prevent the vehicle from moving. After jack-
ing up the vehicle, support the vehicle weight with safety stands at
the points designated for proper lifting before working on the vehi-
cle.
These operations should be done on a level surface.

• 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.

• Before starting repairs which do not require battery power:

Turn off ignition switch.
Disconnect the negative battery terminal.

• If the battery terminals are disconnected, recorded memory of

radio and each control unit is erased.

• To prevent serious burns:

Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.

• Dispose of drained oil or the solvent used for cleaning parts in an

appropriate manner.

• 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.

• Clean all disassembled parts in the designated liquid or solvent

prior to inspection or assembly.

• Replace oil seals, gaskets, packings, O-rings, locking washers,

cotter pins, self-locking nuts, etc. with new ones.

• Replace inner and outer races of tapered roller bearings and needle bearings as a set.
• Arrange the disassembled parts in accordance with their assembled locations and sequence.
• Do not touch the terminals of electrical components which use microcomputers (such as ECM).

Static electricity may damage internal electronic components.

• After disconnecting vacuum or air hoses, attach a tag to indicate the proper connection.

PRECAUTIONS

GI-35

< PRECAUTION >

• Use only the fluids and lubricants specified in this manual.
• Use approved bonding agent, sealants or their equivalents when required.
• Use tools and recommended special tools where specified for safe and efficient service repairs.
• When repairing the fuel, oil, water, vacuum or exhaust systems, check all affected lines for leaks.
• Before servicing the vehicle:

Protect fenders, upholstery and carpeting with appropriate covers.
Take caution that keys, buckles or buttons do not scratch paint.

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 TM sections.

Precaution for Three Way Catalyst

INFOID:0000000005272994

If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.
• Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.
• When checking for ignition spark or measuring engine compression, make tests quickly and only when nec-

essary.

• 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.

Fuel (Regular Unleaded Gasoline Recommended) QR25DE and VQ40DE

INFOID:0000000005272995

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

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.

Precaution for Multiport Fuel Injection System or Engine Control System

INFOID:0000000005272997

• Before connecting or disconnecting any harness connector for the

multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

• Before disconnecting pressurized fuel line from fuel pump to injec-

tors, be sure to release fuel pressure.

• Be careful not to jar components such as ECM and mass air flow

sensor.
