PRECAUTION
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.

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.

• Before disposing ofair bag module andseat beltpre-tensioner, orvehicles equipped withsuch
systems, deploythesystems. Ifsuch systems havealready beendeployed duetoan accident, dis-
pose ofas indicated in"DISPOSING OFAIR BAG MODULE ANDSEAT BELTPRE-TENSIONER" (RS-

24).

• When deploying theairbag module, alwaysusetheSpecial Service Tool;Deployment tool
KV99106400.
• When deploying theairbag module andseat beltpre-tensioner, standatleast 5m (16 ft)away from
the deployment component.
• Due toheat, leave airbag module unattended formore than30minutes afterdeployment. Alsoleave
seat beltpre-tensioner unattendedformore than10minutes afterdeployment.
• Besure towear gloves whenhandling adeployed airbag module andseat beltpre-tensioner.
• Never applywater toadeployed airbag module.
• Wash yourhands cleanafterfinishing- work.
• Donot dispose ofthe airbag module andseat beltpre-tensioner un-deployed.

• Before disassembly, thoroughlycleantheoutside ofthe unit.
• Disassembly shouldbedone inaclean workarea. Itis important toprevent theinternal partsfrom
becoming contaminated bydirt orother foreign matter.
• Place disassembled partsinorder, onaparts rack,fore"asier andproper assembly.
• Use nylon cloths orpaper towels toclean theparts; common shopragscanleave lintthat might
interfere withtheir operation.
• Before inspection orreassembly, carefullycleanallparts withageneral purpose, non-flammable
solvent.
• Before assembly, applyacoat ofrecommended ATF*tohydraulic parts.Vaseline maybeapplied to
