This system includes seat belt switch inputs and dual stage front air bag modules. The SRS system uses the seat belt switches to determine the front air bag deployment, and may only deploy one front air bag, depending on the severity of a collision and whether the front occupants are belted or unbelted. Information necessary to service the system safely is included in the SR and SB section of this Service Man- ual. WARNING: ? To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death in the event of a collision which would result in air bag inflation, all maintenance must be performed by an authorized NISSAN/INFINITI dealer.  Improper maintenance, including incorrect removal and installation of the SRS, can lead to personal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SR section.  Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or har- ness connectors. Precaution for Working with HFC-134a (R-134a) INFOID:0000000001672945 WARNING:  CFC-12 (R-12) refrigerant and HFC-134a (R-134a) refrigerant are not compatible. If the refrigerants are mixed compressor failure is likely to occur. Refer to HA-3, “Contaminated Refrigerant“. To deter- mine the purity of HFC-134a (R-134a) in the vehicle and recovery tank, use refrigerant recovery/recy- cling equipment and refrigerant identifier.  Use only specified oil for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If oil other than that specified is used, compressor failure is likely to occur.  The specified HFC-134a (R-134a) oil rapidly absorbs moisture from the atmosphere. The following handling precautions must be observed: - When removing refrigerant components from a vehicle, immediately cap (seal) the component to minimize the entry of moisture from the atmosphere. - When installing refrigerant components to a vehicle, do not remove the caps (unseal) until just before connecting the components. Connect all refrigerant loop components as quickly as possible to minimize the entry of moisture into system. - Only use the specified oil from a sealed container. Immediately reseal containers of oil. Without proper sealing, oil will become moisture saturated and should not be used. - Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat. Remove HFC-134a (R-134a) from the A/C system using certified service equipment meeting require- ments of SAE J2210 [HFC-134a (R-134a) recycling equipment], or SAE J2209 [HFC-134a (R-134a) recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and oil manufac- turers. - Do not allow the refrigerant oil to come in contact with styrofoam parts. Damage may result.PRECAUTIONS VTL-3C D E F G H J K L M A B VTL N O P Precaution for Procedure without Cowl Top Cover INFOID:0000000001672947 When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc. PIIB3706JVTL-4PREPARATION PREPARATION PREPARATION Commercial Service Tool INFOID:0000000001672948 Tool name Description Power tool Loosening bolts and nuts PBIC0190EIN-CABIN MICROFILTER VTL-5C D E F G H J K L M A B VTL N O P FUNCTION DIAGNOSIS IN-CABIN MICROFILTER Description INFOID:0000000001672949 FUNCTION The air inside the passenger compartment is filtered by the in-cabin microfilters when the heater or A/C controls are set on either the recirculation or fresh mode. The two in-cabin microfilters are located in the front heater and cooling unit assembly. The rear heater and cooling unit assembly only draws in air from the passenger compart- ment to recirculate into the passenger compartment, so the rear heater and cooling unit assembly is not equipped with in-cabin microfilters. REPLACEMENT TIMING Replacement of the two in-cabin microfilters is recommended on a regular interval depending on the driving conditions. Refer to MA-6, “Introduction of Periodic Maintenance“. It may also be necessary to replace the two in-cabin microfilters as part of a component replacement if the in-cabin microfilters are damaged. LJIA0012EVTL-6IN-CABIN MICROFILTER ON-VEHICLE MAINTENANCE IN-CABIN MICROFILTER Removal and Installation INFOID:0000000001672951 REPLACEMENT TIMING Replacement of the two in-cabin microfilters is recommended on a regular interval depending on the driving conditions. Refer to MA-6, “Introduction of Periodic Maintenance“. It may also be necessary to replace the two in-cabin microfilters as part of a component replacement if the in-cabin microfilters are damaged. REPLACEMENT PROCEDURE 1. Open the lower glove box and press in on the sides so that it will open completely allowing it to hang by the cord. 2. Remove the screw and remove the in-cabin microfilter cover. 3. Remove the in-cabin microfilters from the front heater and cool- ing unit housing. 4. Insert the first new in-cabin microfilter into the front heater and cooling unit housing and slide it over to the right. Insert the sec- ond new in-cabin microfilter into the front heater and cooling unit housing. NOTE: The in-cabin microfilters are marked with air flow arrows. The end of the microfilter with the arrow should face the rear of the vehicle. The arrows should point downward. 5. Install the in-cabin microfilter cover.
