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.

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.
