PRECAUTIONS
Service Notice
• When removing orinstalling variousparts,placeacloth orpadding ontothevehicle bodytoprevent
scratches.
• Handle trim,molding, instruments, grille,etc.carefully duringremoving orinstalling. Becareful not
to soil ordamage them.
• Apply sealing compound wherenecessary wheninstalling parts.

parts.
• When replacing anymetal parts(forexample bodyouter panel, members, etc.),besure totake rust
prevention measures.
SupplementalRestraintSystem(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.
