Nissan Versa Note. Manual - part 469

PRECAUTIONS

GI-25

< PRECAUTION >

• 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 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.

Three Way Catalyst

INFOID:0000000009472964

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) HR16DE

INFOID:0000000009472965

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 specif-

ically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - 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.

PRECAUTIONS

Multiport Fuel Injection System or Engine Control System

INFOID:0000000009472966

• 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.

Hoses

INFOID:0000000009472967

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.

PRECAUTIONS

< PRECAUTION >

• After installing plate clamps, apply force to them in the direction of

the arrow, tightening rubber hose equally all around.

Engine Oils

INFOID:0000000009472968

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.

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.

Air Conditioning

INFOID:0000000009472969

Use an approved refrigerant recovery unit any time the air conditioning system must be discharged. Refer to

LIFTING POINT

LIFTING POINT

Special Service Tool

INFOID:0000000009472970

The actual shapes of Kent-Moore tools may differ from those of special service tools illustrated here.

CAUTION:

• Every time the vehicle is lifted up, maintain the complete vehicle curb condition.

• Since the vehicle's center of gravity changes when removing main parts on the front side (engine,

transmission, suspension etc.), support a jack up point on the rear side garage jack with a transmis-

sion jack or equivalent.

• Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,

suspension, etc.), support a jack up point on the front side garage jack with a transmission jack or

equivalent.

• Be careful not to smash or do anything that would affect piping parts.

Garage Jack and Safety Stand

INFOID:0000000009472971

WARNING:

• Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes, tubes,

etc. under the vehicle.

• Never get under the vehicle while it is supported only by the jack. Always use safety stands when

you have to get under the vehicle.

• Place wheel chocks at both front and back of the wheels on the ground.
