The Supplemental Restraint System consistsof driver air bag module (located in the center of the steeringwheel), front passenger air bag module (located on the instrumentpanel on the passenger side), seat belt pre-tensioners, a diagno-sis sensor unit, a crash zone sensor (4WD models), warning lamp,wiring harness and spiral cable.Information necessary to service the system safely is included inthe RS section of this Service Manual.WARNING:¼ To avoid rendering the SRS inoperative, which couldincrease the risk of personal injury or death in the eventof a collision which would result in air bag inflation, allmaintenance should be performed by an authorized NIS-SAN dealer.¼ Improper maintenance, including incorrect removal andinstallation of the SRS, can lead to personal injury causedby unintentional activation of the system. For removal ofSpiral Cable and Air Bag Module, refer to RS-16.¼ Do not use electrical test equipment on any circuit relatedto the SRS unless instructed to in this Service Manual.Spiral cable and wiring harnesses (except “SEAT BELTPRE-TENSIONER”) covered with yellow insulation eitherjust before the harness connectors or for the completeharness are related to the SRS.SGI285GENERAL PRECAUTIONSNGGI0001S02¼ Do not operate the engine for an extended period of timewithout proper exhaust ventilation.Keep the work area well ventilated and free of any inflammablematerials. Special care should be taken when handling anyinflammable or poisonous materials, such as gasoline, refrig-erant gas, etc. When working in a pit or other enclosed area,be sure to properly ventilate the area before working with haz-ardous materials.Do not smoke while working on the vehicle.MAEMLCECFECLMTATTFPDAXSUBRSTRSBTHASCELIDXPRECAUTIONSPrecautionsGI-3 SGI231¼ Before jacking up the vehicle, apply wheel chocks or other tireblocks to the wheels to prevent the vehicle from moving. Afterjacking up the vehicle, support the vehicle weight with safetystands at the points designated for proper lifting before work-ing on the vehicle.These operations should be done on a level surface.¼ When removing a heavy component such as the engine ortransaxle/transmission, be careful not to lose your balance anddrop it. Also, do not allow it to strike adjacent parts, especiallythe brake tubes and master cylinder.SEF289H¼ Before starting repairs which do not require battery power:Turn off ignition switch.Disconnect the negative battery terminal.SGI233¼ To prevent serious burns:Avoid contact with hot metal parts.Do not remove the radiator cap when the engine is hot.SGI234¼ Before servicing the vehicle:Protect fenders, upholstery and carpeting with appropriate cov-ers.Take caution that keys, buckles or buttons do not scratch paint.¼ Clean all disassembled parts in the designated liquid or solventprior to inspection or assembly.¼ Replace oil seals, gaskets, packings, O-rings, locking washers,cotter pins, self-locking nuts, etc. with new ones.¼ Replace inner and outer races of tapered roller bearings andneedle bearings as a set.¼ Arrange the disassembled parts in accordance with theirassembled locations and sequence.¼ Do not touch the terminals of electrical components which usemicrocomputers (such as ECMs).Static electricity may damage internal electronic components.PRECAUTIONSPrecautions (Cont’d)GI-4 ¼ After disconnecting vacuum or air hoses, attach a tag to indi-cate the proper connection.¼ Use only the fluids and lubricants specified in this manual.¼ Use approved bonding agents, sealants or their equivalentswhen required.¼ Use tools and recommended special tools where specified forsafe and efficient service repairs.¼ When repairing fuel, oil, water, vacuum or exhaust systems,check all affected lines for leaks.¼ Dispose of drained oil or the solvent used for cleaning parts inan appropriate manner.¼ Do not attempt to top off the fuel tank after the fuel pumpnozzle shuts off automatically. Continued refueling may causefuel overflow resulting in fuel spray and possibly a fire.WARNING:To prevent ECM from storing the diagnostic trouble codes, donot carelessly disconnect the harness connectors which arerelated to the engine control system and TCM (TransmissionControl Module) system. The connectors should be discon-nected only when working according to the WORK FLOW ofTROUBLE DIAGNOSES in EC and AT sections.SGI787PRECAUTIONS FOR MULTIPORT FUEL INJECTIONSYSTEM OR ENGINE CONTROL SYSTEMNGGI0001S03¼ Before connecting or disconnecting any harness connector forthe multiport fuel injection system or ECM:Turn ignition switch to OFF position.Disconnect negative battery terminal.Otherwise, there may be damage to ECM.¼ Before disconnecting pressurized fuel line from fuel pump toinjectors, be sure to release fuel pressure.¼ Be careful not to jar components such as ECM and mass airflow sensor.PRECAUTIONS FOR THREE WAY CATALYSTNGGI0001S04If a large amount of unburned fuel flows into the catalyst, the cata-lyst temperature will be excessively high. To prevent this, follow theinstructions below:¼ Use unleaded gasoline only. Leaded gasoline will seriouslydamage the three way catalyst.¼ When checking for ignition spark or measuring enginecompression, make tests quickly and only when necessary.¼ Do not run engine when the fuel tank level is low, otherwise theengine may misfire causing damage to the catalyst.Do not place the vehicle on flammable material. Keep flammablematerial off the exhaust pipe and the three way catalyst.MAEMLCECFECLMTATTFPDAXSUBRSTRSBTHASCELIDXPRECAUTIONSPrecautions (Cont’d)GI-5 SMA019DPRECAUTIONS FOR HOSESNGGI0001S08Hose removal and installationNGGI0001S0801¼ To prevent damage to rubber hose, do not pry off rubber hosewith tapered tool or screwdriver.SMA020D¼ To reinstall the rubber hose securely, make sure of hose inser-tion length and clamp orientation. (If tube is equipped withhose stopper, insert rubber hose into tube until it butts upagainst hose stopper.)SMA021DHose clampingNGGI0001S0802¼ If old rubber hose is re-used, install hose clamp in its originalposition (at the indentation where the old clamp was). If thereis a trace of tube bulging left on the old rubber hose, alignrubber hose at that position.¼ Discard old clamps; replace with new ones.SMA022D¼ After installing leaf spring clamps, apply force to them in thedirection of the arrow, tightening rubber hose equally allaround.PRECAUTIONS FOR ENGINE OILSNGGI0001S05Prolonged and repeated contact with used engine oil may causeskin cancer. Try to avoid direct skin contact with used oil.If skin contact is made, wash thoroughly with soap or hand cleaneras soon as possible.Health Protection PrecautionsNGGI0001S0501¼ Avoid prolonged and repeated contact with oils, particularlyused engine oils.¼ Wear protective clothing, including impervious gloves wherepracticable.¼ Do not put oily rags in pockets.¼ Avoid contaminating clothes, particularly underpants, with oil.¼ Heavily soiled clothing and oil-impregnated footwear shouldnot be worn. Overalls must be cleaned regularly.¼ First Aid treatment should be obtained immediately for opencuts and wounds.¼ Use barrier creams, applying them before each work period, tohelp the removal of oil from the skin.PRECAUTIONSPrecautions (Cont’d)GI-6 ¼ Wash with soap and water to ensure all oil is removed (skincleansers and nail brushes will help). Preparations containinglanolin replace the natural skin oils which have been removed.¼ Do not use gasoline, kerosine, diesel fuel, gas oil, thinners orsolvents for cleaning skin.¼ If skin disorders develop, obtain medical advice without delay.¼ Where practicable, degrease components prior to handling.¼ Where there is a risk of eye contact, eye protection should beworn, for example, chemical goggles or face shields, inaddition, an eye wash facility should be provided.Environmental Protection PrecautionsNGGI0001S0502Burning used engine oil in small space heaters or boilers can berecommended only for units of approved design. The heating sys-tem must meet the requirements of HM Inspectorate of Pollution forsmall burners of less than 0.4 MW. If in doubt check with theappropriate local authority and/or manufacturer of the approvedappliance.Dispose of used oil and used oil filters through authorized wastedisposal contractors to licensed waste disposal sites, or to thewaste oil reclamation trade. If in doubt, contact the local authorityfor advice on disposal facilities.It is illegal to pour used oil onto the ground, down sewers or drains,or into water courses.The regulations concerning the pollution vary from country tocountry.PRECAUTIONS FOR FUELNGGI0001S06Use unleaded gasoline with an octane rating of at least 87 AKI(Anti-Knock Index) number (research octane number 91).CAUTION:Use unleaded fuel only. Under no circumstances shouldleaded gasoline be used. It will damage your three way cata-lyst and increase dangerous emissions from your vehicleexhaust.Using a fuel other than that specified could adversely affectthe emission control devices and systems, and could alsoaffect the warranty coverage validity.PRECAUTIONS FOR AIR CONDITIONINGNGGI0001S07Use an approved refrigerant recovery unit any time the air condi-tioning system must be discharged.
