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.
