Precautions forNATS V2.0(ForGasoline Engine
Model)
NATS (Nissan Anti-Theft System)

NATS V2.0willimmobilize theengine ifsomeone triestostart
it without theregistered keyofNATS V2.0.
Both ofthe originally suppliedignitionkeyIDshave been NATS
registered.
The NATS security indicator islocated onthe instrument panel.
The indicator blinkswhentheignition switchisin "OFF" or
"ACC" position. Therefore, NATSwarns outsiders thatthevehi-
cle isequipped withtheanti-theft system.
• When NATSdetects trouble, themalfunction indicatorlamp
(MIL) blinks.
This blinking indicates thattheanti-theft isnot functioning,
so prompt service isrequired.
• When servicing NATS(trouble diagnoses, systeminitialisa-
tion andadditional registration ofother NATS ignition key
IDs), CONSULT hardwareandCONSULT NATSsoftware is
necessary.
Regarding theprocedures ofNATS initialisation andNATS
ignition key
10
registration, refertoCONSULT operation
manual, NATSV2.0.

Therefore, CONSULTNATSsoftware (program cardandoper-
ation manual) mustbekept strictly confidential tomaintain the
integrity ofthe anti-theft function.

• When servicing NATSV2.0(trouble diagnoses, systemini-
tial isation andadditional registration ofother NATS ignition
key IDs),
it
may benecessary tore-register originalkey
identification. Therefore,besure toreceive allkeys from
vehicle owner.
A maximum offour keyIDscan beregistered intoNATS.
• When failing tostart theengine first-time usingthekey of
NATS V2.0,startasfollows.
(1) Turn ignition keyto"OFF".
(2) Wait approx. 5seconds.
(3) Turn ignition keyto"START" againwhilekeeping the
key apart fromanyothers onkey-chain.

SGI285 General
Precautions

• Donot operate theengine foranextended periodoftime
without properexhaust ventilation.
Keep thework areawellventilated andfree ofany flamma-
ble materials. Specialcareshould betaken whenhandling
any flammable orpoisonous materials,suchasgasoline,
refrigerant gas,etc.When working inapit orother enclosed
area, besure toproperly ventilate thearea before working
with hazardous materials.
Do not smoke whileworking onthe vehicle.

GI-3

SEF289HSGI233
SGI234 PRECAUTIONS
General Precautions (Cont'd)

• Before jacking upthe vehicle, applywheel chocks orother
tire blocks tothe wheels toprevent thevehicle frommov-
ing. After jacking upthe vehicle, supportthevehicle weight
with safety stands atthe points designated forproper lifting
before working onthe vehicle.
These operations shouldbedone onalevel surface.
• When removing aheavy component suchasthe engine or
transaxle/transmission, becareful nottolose your balance
and drop them. Also,donot allow themtostrike adjacent
parts, especially thebrake tubesandmaster cylinder.
• Before starting repairswhichdonot require batterypower:
Turn offignition switch.
Disconnect thenegative batteryterminal.
• Toprevent seriousburns:
Avoid contact withhotmetal parts.
Do not remove theradiator capwhen theengine ishot.
• Before servicing thevehicle:
Protect fenders, upholstery andcarpeting withappropriate
covers.
Take caution thatkeys, buckles orbuttons donot scratch
paint.
• Clean alldisassembled partsinthe designated liquidor
solvent priortoinspection orassembly.
• Replace oilseals, gaskets, packings, O-rings,locking
washers, cotterpins,self-locking nuts,etc.with newones.
• Replace innerandouter races oftapered rollerbearings
and needle bearings asaset.
• Arrange thedisassembled partsinaccordance withtheir
assembled locationsandsequence.
• Donot touch theterminals ofelectrical components which
use microcomputers (suchasECMs).
Static electricity maydamage internalelectronic compo-
nents.

GROUND INSPECTION

Ground connections arevery important tothe proper operation ofelectrical andelectronic circuits.
Ground connections areoften exposed tomoisture, dirtand other corrosive elements. Thecorrosion
(rust) canbecome anunwanted resistance. Thisunwanted resistance canchange theway acircuit
works. Electronically controlledcircuitsarevery sensitive toproper grounding. Aloose orcorroded groundcan
drastically affectanelectronically controlledcircuit.Apoor orcorroded groundcaneasily affectthecir-
cuit. Even when theground connection looksclean, therecanbeathin film ofrust onthe surface.
When inspecting aground connection followtheserules:
1. Remove theground boltscrew orclip.
2. Inspect allmating surfaces fortarnish, dirt,rust, etc.
3. Clean asrequired toassure goodcontact.
4. Reinstall boltorscrew securely.
5. Inspect for"add-on" accessories whichmaybeinterfering withtheground circuit.
6. Ifseveral wiresarecrimped intoone ground eyeletterminal, checkforproper crimps. Makesure
all ofthe wires areclean, securely fastened andproviding agood ground path.Ifmultiple wiresare
cased inone eyelet makesurenoground wireshaveexcess wireinsulation.
