OUTLINE OF MODIFICATIONS
GENERAL
lVarious running changes on engine control system, electrical systems, body etc. Note that the introduc-
tion timing of some of the running changes may not be entirely in line with the above mentioned VIN.
lFor some running changes, the VIN (Vehicle Identification Number) is mentioned to specify the timing
of the change implemention.
The VIN No. may not be an exact number, there is an error range of approx. 50 cars.

Observe the following precautions to ensure safe and
proper servicing.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System ªAir Bagº and ªSeat Belt
Pre-tensionerº, used along with a seat belt, help to reduce the
risk or severity of injury to the driver and front passenger in a
frontal collision. The Supplemental Restraint System consists of
air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-
tensioners, a diagnosis sensor unit, warning lamp, wiring har-
ness and spiral cable.
If the vehicle is equipped with side air bag as the Supplemental
Restraint System, the side air bag used along with the seat belt
helps to reduce the risk or severity of injury to the driver and front
passenger in a side collision. The side air bag consists of air bag
modules (located in the outer side of front seats), satellite sensor,
diagnosis sensor unit (which is one of components of air bags for
a frontal collision), wiring harness, warning lamp (which is one of
components of air bags for a frontal collision).
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 do so in this
Service Manual. SRS wiring harnesses are covered with
yellow insulation (either just before the harness connec-
tors 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 with-
out 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 flashes when the ignition switch is in ªLOCKº or
ªAccº position. Therefore, NATS warns outsiders that the vehicle
is equipped with the anti-theft system.
lWhen NATS detects trouble, the malfunction indicator (MI)
flashes.
This flashing 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-II hardware and CONSULT-II NATS soft-
ware is necessary.

PRECAUTIONS
GI-3
Page 1799 of 2267

Regarding the procedures of NATS initialisation and NATS igni-
tion key ID registration, refer to CONSULT-II operation manual
for 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.
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 obtain all keys from vehicle
owner.
A maximum of four key IDs can be registered into NATS.
Precautions for Super Lock System
Locking the driver's door or front passenger's door with the key
or remote control will lock all doors and activate the Super Lock
System.
The Super Lock System is designed to prevent theft as it can
only be released when a front door is unlocked using a key or
remote control.
This means, none of the door locks can be operated from the
inside using the door lock knob when the Super Lock System is
activated.
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 flammable
materials. Special care should be taken when handling any
flammable 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
hazardous materials.
Do not smoke while working on the vehicle.
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 care 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 solvent used for cleaning parts in
an appropriate manner.
