Observe the following precautions to ensure safe and
proper servicing. These precautions are not described in
each individual section.
Precautions for Supplemental Restraint
System (SRS) ``AIR BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with
a seat belt, helps to reduce the risk or severity of injury to the
driver in a frontal collision. The Supplemental Restraint System
consists of an air bag module (located in the center of the steer-
ing wheel), a diagnosis sensor unit, warning lamp, wiring harness
and spiral cable. Information necessary to service the system
safely is included in theRS sectionof this Service Manual.
WARNING:
lTo 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 must be performed by an authorized
NISSAN dealer.
lImproper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury
caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit
related to the SRS unless instructed to in this Service
Manual. SRS wiring harnesses are covered with yellow
insulation either just before the harness connectors or
for the complete harness, for easy identification.
Precautions for Supplemental Restraint
System (SRS) ``AIR BAG'' (2WD models)
The Supplemental Restraint System ``AIR BAG'', used along with
a seat belt, helps to reduce the risk or severity of injury to the
driver in a frontal collision. The Supplemental Restraint System
consists of an air bag module (located in the center of the steer-
ing wheel), a diagnosis sensor unit, warning lamp and spiral
cable. Information necessary to service the system safely is
included in theRS sectionof this Service Manual.
WARNING:

increase the risk of personal injury or death in the event
of a collision which would result in air bag inflation, all
maintenance must be performed by an authorized
NISSAN dealer.
lImproper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury
caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit
related to the SRS.

PRECAUTIONS

Precautions for NATS
NATS (Nissan Anti-Theft System)
NATS will immobilize the engine if someone tries to start it with-
out the registered key of NATS.
All 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 ``OFF'' or
``ACC'' position. Therefore, NATS warns outsiders that the
vehicle is equipped with the anti-theft system.
lGasoline engine:
When NATS detects trouble, the malfunction indicator lamp
(MIL) blinks.
This blinking indicates that the anti-theft is not functioning, so
prompt service is required.
lDiesel engine:
When NATS detects trouble while engine is running or igni-
tion switch in ``ON'' position, the NATS security indicator
comes on.
This indicates that the anti-theft is not functioning, so prompt
service is required.
lWhen servicing NATS (trouble diagnoses, system initialisa-
tion and additional registration of other NATS ignition key
IDs), CONSULT hardware and CONSULT NATS software is
necessary.
Regarding the procedures of NATS initialisation and NATS
ignition key ID registration, refer to CONSULT operation
manual, NATS.
Therefore, CONSULT NATS software (program card and
operation manual) must be kept strictly confidential to main-
tain the integrity of the anti-theft function.
lWhen servicing NATS (trouble diagnoses, system initialisa-
tion and additional registration of other NATS ignition key
IDs), it may be necessary to re-register original key identifi-
cation. Therefore, be sure to receive all keys from vehicle
owner.
A maximum of four key IDs can be registered into NATS.
General Precautions
lDo not operate the engine for an extended period of time
without proper exhaust ventilation.
Keep the work area well ventilated and free of any inflam-
mable materials. Special care should be taken when han-
dling any inflammable or poisonous materials, such as
gasoline, refrigerant gas, etc. When working in a pit or other
enclosed area, be sure to properly ventilate the area before
working with hazardous materials.
Do not smoke while working on the vehicle.

PRECAUTIONS
GI-2

lBefore 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
working on the vehicle.
These operations should be done on a level surface.
lWhen removing a heavy component such as the engine or
transaxle/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.
lBefore starting repairs which do not require battery power:
Turn off ignition switch.
Disconnect the negative battery terminal.
lTo prevent serious burns:
Avoid contact with hot metal parts.
Do not remove the radiator cap when the engine is hot.
lBefore servicing the vehicle:
Protect fenders, upholstery and carpeting with appropriate
covers.
Take caution that keys, buckles or buttons do not scratch
paint.
lClean all disassembled parts in the designated liquid or sol-
vent prior to inspection or assembly.
lReplace oil seals, gaskets, packings, O-rings, locking
washers, cotter pins, self-locking nuts, etc. with new ones.
lReplace inner and outer races of tapered roller bearings and
needle bearings as a set.
lArrange the disassembled parts in accordance with their
assembled locations and sequence.
lDo not touch the terminals of electrical components which
use microcomputers (such as ECMs).
Static electricity may damage internal electronic compo-
nents.

lAfter disconnecting vacuum or air hoses, attach a tag to
indicate the proper connection.
lUse only the fluids and lubricants specified in this manual.
lUse approved bonding agent, sealants or their equivalents
when required.
lUse tools and recommended special tools where specified
for safe and efficient service repairs.
lWhen repairing the fuel, oil, water, vacuum or exhaust
systems, check all affected lines for leaks.
lDispose of drained oil or the solvent used for cleaning parts
in an appropriate manner.
WARNING:
To prevent ECM from storing the diagnostic trouble codes,
do not carelessly disconnect the harness connectors which
are related to the ECCS 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 section.
Precautions for Multiport Fuel Injection
System or ECCS Engine
lBefore connecting or disconnecting any harness connector
for the multiport fuel injection system or ECM (Engine Con-
trol Module):
Turn ignition switch to ``OFF'' position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
lBefore disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
lBe careful not to jar components such as ECM and mass air
flow sensor.
Precautions for Three Way Catalyst
(If so equipped)
If a large amount of unburned fuel flows into the catalyst, the
catalyst temperature will be excessively high. To prevent this,
follow the instructions below:
lUse unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
lWhen checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
lDo 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 Engine Oils
Prolonged and repeated contact with used engine oil may cause
skin cancer. Try to avoid direct skin contact with used oil.
