Front FogLamp BulbReplacement

The front foglamp isasemi-sealed beamtypewhich usesa
replaceable halogenbulb.

• Grasp onlytheplastic basewhen handling thebulb. Never
touch theglass envelope.

1. Disconnect thebattery cable.
2. Disconnect theharness connector fromtheback sideofthe
bulb.
3. Turn thebulb retaining ringcounterclockwise untilitis free
from thefront foglamp reflector, andthen remove it.
4. Pull offthe rubber cap.
5. Remove thefront foglamp bulbcarefully. Donot shake or
rotate thebulb when removing it.
6. Install inthe reverse orderofremoval.

CAUTION:
.' Donot leave frontfoglamp reflector withoutbulbforalong
period oftime. Dust, moisture, smoke,etc.entering frontfog
lamp bodymayaffect theperformance ofthe front foglamp.
Remove frontfoglamp bulbfrom thefront foglamp reflec-
tor just before areplacement bulbisinstalled.
Front FogLamp Aiming Adjustment

Before performing aimingadjustment, makesureofthe follow-
ing.
a. Keep alltires inflated tocorrect pressure.
b. Place vehicle onlevel ground.
c. See thatvehicle isunloaded (exceptforfull levels of
coolant, engineoiland fuel, andspare tire,jack, andtools).
Have thedriver orequivalent weightplaced indriver's seat.

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 ~nany circuit related tothe SRS unless instructed tointhis
Service Manual. SRSwiring harnesses arecovered withyellow insulation eitherjustbefore the
harness connectors orfor the complete harness,foreasy identification.
