PRECAUTIONSANDPREPARATION
Supplemental RestraintSystem(SRS)"AIR
BAG" (DualAirBag System)

The Supplemental RestraintSystem"AirBag", usedalong withaseat belt,helps toreduce therisk or
severity ofinjury tothe driver andfront passenger inafrontal collision. TheSupplemental Restraint
System consists ofair bag modules (locatedinthe center ofthe steering wheelandonthe instrument
panel onthe passenger side),adiagnosis sensorunit,warning lamp,wiring harness andspiral cable.
Information necessarytoservice thesystem safelyisincluded inthe
RSsection
ofthis Service Manual.

WARNING:
• Toavoid rendering theSRS inoperative, whichcouldincrease therisk ofpersonal injuryordeath
in the event ofacollision whichwould resultinair bag inflation, allmaintenance mustbeperformed
by an authorized NISSANdealer. •
• Improper maintenance, includingincorrectremovalandinstallation ofthe SRS, canlead topersonal
injury caused byunintentional activationofthe system.
• Donot use electrical testequipment ~nany circuit related tothe SRS unless instructed tointhis
Service Manual. SRSwiring harnesses arecovered withyellow insulation eitherjustbefore the
harness connectors orfor the complete harness,foreasy identification.

PRECAUTIONS

Observe thefollowing precautions toensure safeandproper
servicing.

Supplemental RestraintSystem(SRS)"AIR
BAG" (DualAirBag System)

The Supplemental RestraintSystem"AirBag" usedalong with
a seat belt,helps toreduce therisk orseverity ofinjury tothe
driver andfront passenger inafrontal collision. TheSupple-
mental Restraint Systemconsists ofair bag modules (located
in the center ofthe steering wheelandonthe instrument panel
on the passenger side),adiagnosis sensorunit,warning lamp,
wiring harness andspiral cable. Information necessarytoser-
vice thesystem safelyisincluded inthe RSsection ofthis Ser-
vice Manual.
WARNING:
• To avoid rendering theSRS inoperative, whichcould
increase therisk ofpersonal injuryordeath inthe event of
a collision whichwould resultinair bag inflation, allmain-
tenance mustbeperformed byan authorized NISSAN
dealer.
• Improper maintenance, includingincorrectremovaland
installation ofthe SRS, canlead topersonal injurycaused
by unintentional activationofthe system.
• Donot use electrical testequipment onany circuit related
to the SRS unless instructed tointhis Service Manual. SRS
wiring harnesses arecovered withyellow insulation either
just before theharness connectors orfor the complete
harness, foreasy identification.

to the SRS unless instructed tointhis Service Manual.

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.
