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 onany 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 forSRS "AirBag" and"Seat Belt
Pre-tensioner" Service
• Donot use acircuit testertocheck SRScircuits.
• Before servicing theSRS. turnignition switch"OFF", disconnect bothbattery cablesandwait forat
least 10minutes.
For approximately 10minutes afterthecables areremoved, itis still possible forthe airbag to
deploy. Therefore, donot work onany SRS connectors orwires untilatleast 10minutes havepassed.
• For single airbag system, donot separate diagnosis sensorunitfrom steering wheel.
• For dual airbag system. diagnosis sensorunitmust always beinstalled withtheir arrow marks
"Q"
pointing towards thefront ofthe vehicle forproper operation. Alsocheck diagnosis sensorunitfor
cracks. deformities orrust before installation andreplace asrequired.
• The spiral cablemustbealigned withtheneutral position sinceitsrotations arelimited. Donot
attempt toturn steering wheelorcolumn afterremoval ofsteering gear.
• Handle airbag module carefully. Alwaysplaceitwith thepad side facing upward.
• Donot use oldbolts afterremoving anySRS parts; replace withnewones. Conduct self-diagnosis
to check entire SRSforproper function.
• For dual airbag system, instrument panelassembly shouldbereplaced afterairbag inflates.

1. Check "AIRBAG" warning lampoperation
After turning ignition keyto"ON" position, "AIRBAG"
warning lampilluminates. The"AIR BAG" warning lamp
will turn offafter about 7seconds ifno malfunction is
detected. If any ofthe following airbag warning lampconditions
occur, immediately checktheairbag system. RefertoRS-32
and 43for details.
