PRECAUTIONS PRECAUTIONS Description
PFP:00001
GI EAS001G7
Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER”
B
EAS001G8
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 SRS and SB section of this Service Manual. 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 SRS 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 harness connectors.
Precautions for NVIS/IVIS (NISSAN/INFINITI VEHICLE IMMOBILIZER SYSTEM NATS) (If Equipped)
EAS001YS
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. 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. ● 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. ● 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 registration, 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. ● 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 registered into NVIS/IVIS (NATS). ● 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 General Precautions ●
EAS001G9
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 inflammable 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 materials. Do not smoke while working on the vehicle. SGI285
●
●
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. When removing a heavy component such as the engine or transaxle/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
●
●
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.
SEF289H
●
● ●
● ● ● ● ● ● ●
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 SGI233 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. Use only the fluids and lubricants specified in this manual.

PRECAUTIONS ● ●
●
Use approved bonding agent, sealants or their equivalents when required. Use hand tools, power tools (disassembly only) 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.

Precautions for Three Way Catalyst
J
EAS001GA
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 necessary. ● 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
EAS001MP
QR25DE MODELS 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 specifically 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.
VQ40DE MODELS 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 specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicles - FFV models). Revision: November 2005

PRECAUTIONS 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. 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.
Precautions for Multiport Fuel Injection System or Engine Control System ●
● ●
EAS001GC
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 injectors, be sure to release fuel pressure. Be careful not to jar components such as ECM and mass air flow sensor. SGI787
Precautions for Hoses
EAS001GD
HOSE REMOVAL AND INSTALLATION ●
To prevent damage to rubber hose, do not pry off rubber hose with tapered tool or screwdriver.
