Precaution for Procedur e without Cowl Top CoverINFOID:0000000001612933
When performing the procedure after removing cowl top cover, cover
the lower end of windshield with urethane, etc.
General PrecautionINFOID:0000000001325654
 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 ot her 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.
 Battery posts, terminals and related accessories contain lead and
lead compounds. Wash hands after handling.

PRECAUTIONS
 To prevent serious burns:Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
 Dispose of or recycle 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 com ponents which use microcomputers (such as ECM).
Static electricity may damage internal electronic components.
 After disconnecting vacuum or air hoses, atta ch a tag to indicate the proper connection.
 Use only the fluids and lubricants specified in this manual.
 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.
 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 tro uble codes, do not carelessly disconnect the harness
connectors which are related to the engine cont rol system and TCM (transmission control module)
system. The connectors should be disconnected on ly when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precaution for Three Way CatalystINFOID:0000000001325655
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.
Precaution for Fuel (Unlead ed Premium Gasoline Recommended)INFOID:0000000001325656
VQ35DE
INFINITI recommends the use of unleaded premium gasoli ne with an octane rating of at least 91 AKI (Anti-
Knock Index) number (Research octane number 96).
If unleaded premium gasoline is not available, you may use unleaded regular gasoline with an octane rating of
at least 87AKI number (Research octane number 91), but you may notice a decrease in performance.
CAUTION:
Do not use leaded gasoli ne. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unlead ed gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fu el other than that specified could adversely affect
the emission control devices and systems, and could also affect the warranty coverage validity.
Precaution for Fuel (Unleaded Premium Gasoline Required)INFOID:0000000001325657
VK45DE
Use unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research
octane number 96).
If unleaded premium gasoline is not available, unleaded r egular gasoline with an octane rating of at least 87
AKI number (Research octane number 91) can be us ed, but only under the following precautions:
 have the fuel tank filled only partially with unl eaded regular gasoline, and fill up with unleaded premium gas-
oline as soon as possible.
 avoid full throttle driving and abrupt acceleration.
However, for maximum vehicle performance, the u se of unleaded premium gasoline is recommended.
CAUTION:
Do not use leaded gasoli ne. Using leaded gasoline will damage the three way catalyst. Do not use E-85
fuel (85% fuel ethanol, 15% unlead ed gasoline) unless the vehicle is specifically designed for E-85 fuel
(i.e. Flexible Fuel Vehicle - FFV models). Using a fu el 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 Inject ion System or Engine Control SystemINFOID:0000000001325658
 Before connecting or disconnecti ng 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.
