General Precaution

INFOID:0000000006243360

• 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.

< PRECAUTION >

PRECAUTIONS

• 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.

• 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 All Mode 4WD System

INFOID:0000000006243361

Even if the 2WD mode is selected, the All mode 4WD system occasionally changes from 2WD to 4WD auto-

matically depending on the driving conditions.

When spinning the front wheels by running the engine with the front wheels jacked up or mounted on the free

rollers / or a chassis dynamometer, be careful because the vehicle may suddenly move due to the driving

force from the rear wheels.

To avoid personal injury and vehicle damage, use one of the following methods when working with the front

wheels drive force and spinning freely.

• Remove the propeller shaft.

• Use free rollers / chassis dynamometer designed for 4WD vehicles.

Precaution for Three Way Catalyst

INFOID:0000000006243362

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 (Unleaded Premium Gasoline Recommended)

INFOID:0000000006243363

NISSAN recommends the use of 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, you may

use unleaded regular gasoline with an octane rating of at least 87 AKI number (Research octane number 91),

but you may notice a decrease in performance.

CAUTION:

SGI234

2011 Pathfinder

PRECAUTIONS

GI-27

< PRECAUTION >

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:0000000006243364

• 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.

Precaution for Hoses

INFOID:0000000006243365

HOSE REMOVAL AND INSTALLATION

• To prevent damage to rubber hose, do not pry off rubber hose with

tapered tool or screwdriver.

• To reinstall the rubber hose securely, make sure that hose insertion

length and orientation is correct. (If tube is equipped with hose

stopper, insert rubber hose into tube until it butts up against hose

stopper.)

HOSE CLAMPING

• If old rubber hose is re-used, install hose clamp in its original posi-

tion (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.

• Discard old clamps; replace with new ones.

Precaution for Engine Oils

INFOID:0000000006243366

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

• Avoid prolonged and repeated contact with oils, particularly used engine oils.

• Wear protective clothing, including impervious gloves where practicable.

• Do not put oily rags in pockets.

• Avoid contaminating clothes, particularly underpants, with oil.

• Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu-

larly.

• First aid treatment should be obtained immediately for open cuts and wounds.

• Use barrier creams, applying them before each work period, to help the removal of oil from the skin.

• Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-

tions containing lanolin replace the natural skin oils which have been removed.

• Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.

• If skin disorders develop, obtain medical advice without delay.

• Where practical, degrease components prior to handling.

• 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.

Precaution for Air Conditioning
