Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
1. Do not operate the engine for an extended period of time with-
out 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, refriger-
ant gas, etc. When working in a pit or other enclosed area, be
sure to properly ventilate the area before working with hazard-
ous materials.
Do not smoke while working on the vehicle.
2. 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 and towing
before working on the vehicle.
These operations should be done on a level surface.
3. When removing a heavy component such as the engine or
transaxle/transmission, take care not to lose your balance and
drop it. Also, do not allow it to strike adjacent parts, especially
the brake tubes and master cylinder.
4. Before starting repairs which do not require battery power,
always turn off the ignition switch, then disconnect the ground
cable from the battery to prevent accidental short circuit.
5. To prevent serious burns, avoid contact with hot metal parts
such as the radiator, exhaust manifold, tail pipe and muffler. Do
not remove the radiator cap when the engine is hot.

insulation (either just before the harness connectors or for
the complete harness), for easy identification.
Precautions for NATS
NATS (Nissan Anti-Theft System)
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 NATS security indicator is located on the instrument panel. The
indicator blinks when the ignition switch is in ªOFFº or ªACCº posi-
tion. Therefore, NATS warns outsiders that the vehicle is equipped
with the anti-theft system.
IWhen NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
IIf the malfunction indicator lamp comes on while the engine is
running, return the vehicle to the workshop before turning the
ignition switch ªOFFº.
Once the ignition switch is turned ªOFFº, the engine can not be
started.
IWhen servicing NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs) CON-
SULT-II hardware and CONSULT-II NATS software is neces-
sary.
Regarding the procedures of NATS initialization and NATS igni-
tion key ID registration, refer to CONSULT-II operation manual,
NATS.
Therefore, CONSULT-II NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
IWhen servicing NATS (trouble diagnoses, system initialization
and additional registration of other 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 five key IDs can be registered into NATS.
IWhen failing to start the engine first-time using the key of
NATS, starts as follows:
(1) Turn ignition key to ªOFFº.
(2) Wait approx. 5 seconds.
(3) Turn ignition key to ªSTARTº again while keeping the key
apart from any others on key-chain.

Precautions for Multiport Fuel Injection System
or Engine Control System
1. Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure to eliminate danger.
3. Be careful not to jar components such as control unit and air
flow meter.
Precautions for Catalyst
If a large amount of unburned fuel enters the converter, the con-
verter temperature will rise to excessively high values. To prevent
this, follow the procedure below:
1. Use unleaded gasoline only. Leaded gasoline will seriously
damage the catalytic converter.
2. When checking for ignition spark or measuring engine
compression, perform tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, as a result
the engine may misfire causing damage to the converter.
4. Do not place the vehicle on inflammable material. Keep inflam-
mable material off the exhaust pipe.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
For proper operation of the system, follow the procedure below:
1. Always use the recommended oil. Follow the instructions for
proper time to change the oil and proper oil level.
2. Avoid accelerating engine to a high rpm immediately after start-
ing.
3. If engine had been operating at high rpm for an extended period
of time, let it idle for a few minutes prior to shutting it off.

Precautions for Fuel
DIESEL ENGINE*:
Diesel fuel of at least 50 cetane for ZD30DDTi engine.
* If two types of diesel fuel are available, use summer or winter
fuel properly according to the following temperature conditions.
IAbove þ7ÉC (20ÉF) ... Summer type diesel fuel.
IBelow þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
IDo not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
IDo not use summer fuel at temperature below þ7ÉC (20ÉF).
The cold temperature will cause wax to form in the fuel. As
a result, it may prevent the engine from running smoothly.
IDo not add gasoline or other alternate fuels to diesel fuel.
Precautions for Engine Oils
Prolonged and repeated contact with mineral oil will result in the
removal of natural fats from the skin, leading to dryness, irritation
and dermatitis. In addition, used engine oil contains potentially
harmful contaminants which may cause skin cancer. Adequate
means of skin protection and washing facilities must be provided.
HEALTH PROTECTION PRECAUTIONS
1. Avoid prolonged and repeated contact with oils, particularly
used engine oils.
2. Wear protective clothing, including impervious gloves where
practicable.
3. Do not put oily rags in pockets.
4. Avoid contaminating clothes, particularly underwear, with oil.
5. Heavily soiled clothing and oil-impregnated footwear should not
be worn. Overalls must be cleaned regularly.
6. First Aid treatment should be obtained immediately for open
cuts and wounds.
7. Use barrier creams, applying them before each work period, to
help the removal of oil from the skin.
8. Wash with soap and water to ensure all oil is removed (skin
cleansers and nail brushes will help). Preparations containing
lanolin replace the natural skin oils which have been removed.
9. Do not use petrol, kerosine, diesel fuel, gas oil, thinners or sol-
vents for cleaning skin.
10. If skin disorders develop, obtain medical advice without delay.
11. Where practicable, degrease components prior to handling.
12. 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.
(For the United Kingdom, see also HSE Cautionary Notice SHW
397 ªEffects of Mineral Oil on the Skinº.)
ENVIRONMENTAL PROTECTION PRECAUTIONS
Burning used engine oil in small space heaters or boilers can be
recommended only for units of approved design. The heating sys-
tem must meet the requirements of HM Inspectorate of Pollution for
small burners of less than 0.4 MW. If in doubt check with the
appropriate local authority and/or manufacturer of the approved
appliance.
PRECAUTIONS
GI-6

Dispose of used oil and used oil filters through authorized waste
disposal contractors to licensed waste disposal 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 courses.
The regulations concerning the pollution of the environment
will vary from country to country.
