PRECAUTIONS
Precautions
Precautions NJGI0001
Observe the following precautions to ensure safe and proper
servicing. These precautions are not described in each indi-
vidual section.
PRECAUTIONS FOR SUPPLEMENTAL RESTRAINT
SYSTEM (SRS) "AIR BAG" AND "SEAT BELT
PRE-TENSIONER" NJGI0001S01
The Supplemental Restraint System such as "AIR BAG" and "SEAT
BELT PRE-TENSIONER" used along with a seat belt, helps to
reduce the risk or severity of injury to the driver and front passen-
ger for certain types of collision. The SRS system composition
which is available to NISSAN MODEL N16 is as follows (The com-
position varies according to the destination and optional equip-
ment.):
SGI646 + For a frontal collision
The Supplemental Restraint System consists of driver air bag
module (located in the center of the steering wheel), front pas-
senger air bag module (located on the instrument panel on
passenger side), front seat belt pre-tensioners, a diagnoses
sensor unit, warning lamp, wiring harness and spiral cable.
+ For a side collision
The Supplemental Restraint System consists of front side air
bag module (located in the outer side of front seat), side air bag
(satellite) sensor, diagnoses sensor unit (one of components of
air bags for a frontal collision), wiring harness, warning lamp
(one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in
the RS 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 should be performed by an authorized
NISSAN 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 RS 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 harness
connector.
PRECAUTIONS FOR NATS (NISSAN ANTI-THEFT
SYSTEM) NJGI0001S02
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.
GI-3
PRECAUTIONS
Precautions (Cont'd)
The security indicator is located on the combi meter. The indicator
blinks when the ignition switch is in "OFF" or "ACC" position.
Therefore, NATS warns outsiders that the vehicle is equipped with
the anti-theft system.
+ When 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 NATS (trouble diagnoses, system initialization
and additional registration of other NATS ignition key IDs),
CONSULT-II hardware and CONSULT-II NATS software is
necessary.
Regarding the procedures of NATS initialization and NATS
ignition 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.
+ When 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.
+ When failing to start the engine first time using the key of
NATS, start as follows.
a) Leave the ignition key in "ON" position for approximately 5
seconds.
b) Turn ignition key to "OFF" or "LOCK" position and wait approxi-
mately 5 seconds.
c) Repeat step 1 and 2 again.
d) Restart the engine while keeping the key separate from any
others on key-chain.
GENERAL PRECAUTIONS NJGI0001S03
+ 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, refrig-
erant gas, etc. When working in a pit or other enclosed area,
be sure to properly ventilate the area before working with haz-
ardous 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 work-
ing on the vehicle.
These operations should be done on a level surface.
+ When removing a heavy component such as the engine or
transaxle, 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
GI-4
PRECAUTIONS
Precautions (Cont'd)
+ Before starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
SEF289H
+ To prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
SGI233
+ Before servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate cov-
ers.
Take caution that keys, buckles or buttons do not scratch paint.
SGI234
+ 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 components which use
microcomputers (such as ECMs).
Static electricity may damage internal electronic components.
+ After disconnecting vacuum or air hoses, attach a tag to indi-
cate 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.
+ Dispose of drained oil or the solvent used for cleaning parts in
an appropriate manner.
GI-5
PRECAUTIONS
Precautions (Cont'd)
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.
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 discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
PRECAUTIONS FOR MULTIPORT FUEL INJECTION
SYSTEM OR ENGINE CONTROL SYSTEM NJGI0001S04
+ 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
SGI787 flow sensor.
PRECAUTIONS FOR THREE WAY CATALYST NJGI0001S05
If a large amount of unburned fuel flows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+ 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 HOSES NJGI0001S06
Hose Removal and Installation NJGI0001S0601
+ To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.
SMA019D
GI-6
PRECAUTIONS
Precautions (Cont'd)
+ To reinstall the rubber hose securely, make sure of hose inser-
tion length and clamp orientation. (If tube is equipped with
hose stopper, insert rubber hose into tube until it butts up
against hose stopper.)
SMA020D
Hose Clamping NJGI0001S0602
+ If old rubber hose is re-used, install hose clamp in its original
position (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.
SMA021D
+ After installing leaf spring clamps, apply force to them in the
direction of the arrow, tightening rubber hose equally all
around.
SMA022D
PRECAUTIONS FOR ENGINE OILS NJGI0001S07
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 NJGI0001S0701
+ 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 underclothing, with
oil.
+ Heavily soiled clothing and oil-impregnated footwear should
not be worn. Overalls must be cleaned regularly.
+ 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). Preparations containing
lanolin replace the natural skin oils which have been removed.
GI-7
PRECAUTIONS
Precautions (Cont'd)
+ Do not use gasoline, kerosine, diesel fuel, gas oil, thinners or
solvents for cleaning skin.
+ If skin disorders develop, obtain medical advice without delay.
+ Where practicable, 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 addi-
tion an eye wash facility should be provided.
Environmental Protection Precautions NJGI0001S0702
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.
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 vary between
regions.
