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 SRS 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 SRS 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. PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS WARNING: • When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni- tion ON or engine running, DO NOT use air or electric power tools or strike near the sensor(s) with a hammer. Heavy vibration could activate the sensor(s) and deploy the air bag(s), possibly causing serious injury. • When using air or electric power tools or hammers, always switch the Ignition OFF, disconnect the battery, and wait at least 3 minutes before performing any service. Precaution Necessary for Steering Wheel Rotation After Battery Disconnect INFOID:0000000007329054 NOTE: • This Procedure is applied only to models with Intelligent Key system and NATS (NISSAN ANTI-THEFT SYS- TEM). • Remove and install all control units after disconnecting both battery cables with the ignition knob in the ″LOCK″ position. • Always use CONSULT to perform self-diagnosis as a part of each function inspection after finishing work. If DTC is detected, perform trouble diagnosis according to self-diagnostic results. For models equipped with the Intelligent Key system and NATS, an electrically controlled steering lock mech- anism is adopted on the key cylinder. For this reason, if the battery is disconnected or if the battery is discharged, the steering wheel will lock and steering wheel rotation will become impossible. If steering wheel rotation is required when battery power is interrupted, follow the procedure below before starting the repair operation. OPERATION PROCEDURE 1. Connect both battery cables. NOTE: Supply power using jumper cables if battery is discharged. 2. Use the Intelligent Key or mechanical key to turn the ignition switch to the ″ACC″ position. At this time, the steering lock will be released. 3. Disconnect both battery cables. The steering lock will remain released and the steering wheel can be rotated. 4. Perform the necessary repair operation. Revision: July 2011 2012 Versa MTC-4 < SERVICE INFORMATION > PRECAUTIONS 5. When the repair work is completed, return the ignition switch to the ″LOCK″ position before connecting the battery cables. (At this time, the steering lock mechanism will engage.) 6. Perform a self-diagnosis check of all control units using CONSULT. Precaution for Work INFOID:0000000007795977 • When removing or disassembling each component, be careful not to damage or deform it. If a component may be subject to interference, be sure to protect it with a shop cloth. • When removing (disengaging) components with a screwdriver or similar tool, be sure to wrap the component with a shop cloth or vinyl tape to protect it. • Protect the removed parts with a shop cloth and prevent them from being dropped. • Replace a deformed or damaged clip. • If a part is specified as a non-reusable part, always replace it with new one. • Be sure to tighten bolts and nuts securely to the specified torque. • After installation is complete, be sure to check that each part works properly. • Follow the steps below to clean components. - Water soluble dirt: Dip a soft cloth into lukewarm water, and wring the water out of the cloth to wipe the dirty area. Then rub with a soft and dry cloth. - Oily dirt: Dip a soft cloth into lukewarm water with mild detergent (concentration: within 2 to 3%), and wipe the dirty area. Then dip a cloth into fresh water, and wring the water out of the cloth to wipe the detergent off. Then rub with a soft and dry cloth. • Do not use organic solvent such as thinner, benzene, alcohol, or gasoline. • For genuine leather seats, use a genuine leather seat cleaner.

These refrigerants must never be mixed, even in the smallest amounts. If the refrigerants are mixed a compressor mal- function is likely to occur. • 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 malfunction 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. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci- dental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and oil manufacturers. PIIB3706J Revision: July 2011 2012 Versa PRECAUTIONS MTC-5 < SERVICE INFORMATION > C D E F G H I K L M A B MTC N O P - Do not allow A/C oil to come in contact with styrofoam parts. Damage may result. General Refrigerant Precaution INFOID:0000000007329057 WARNING: • Avoid breathing A/C refrigerant and oil vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acci- dental system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and oil manufacturers. • Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the refrigerant every time an air conditioning system is discharged. • Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air conditioning system. • Do not store or heat refrigerant containers above 52°C (126° F). • Do not heat a refrigerant container with an open flame; if container warming is required, place the bottom of the container in a warm pail of water. • Do not intentionally drop, puncture, or incinerate refrigerant containers. • Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns. • Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suf- focation. • Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condition- ing systems with compressed air during repair. Some mixtures of air and HFC-134a (R-134a) have been shown to be combustible at elevated pressures. These mixtures, if ignited, may cause injury or property damage. Additional health and safety information may be obtained from refrigerant manu- facturers. Oil Precaution INFOID:0000000007329058 • 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 malfunction 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 con- necting 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 seal- ing, 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. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If accidental system discharge occurs, ventilate work area before resuming service. Additional health and safety informa- tion may be obtained from refrigerant and oil manufacturers. • Do not allow A/C oil to come in contact with styrofoam parts. Damage may result. Precaution for Refrigerant Connection INFOID:0000000007329059 A new type refrigerant connection has been introduced to all refrigerant lines except the following location. • Expansion valve to evaporator • Refrigerant pressure sensor to condenser Revision: July 2011 2012 Versa MTC-6 < SERVICE INFORMATION > PRECAUTIONS FEATURES OF NEW TYPE REFRIGERANT CONNECTION • The O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi- nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing charac- teristics. • The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby facili- tating piping connections. O-RING AND REFRIGERANT CONNECTION MR18DE - TYPE 1 SHA815E SJIA0697E Revision: July 2011 2012 Versa PRECAUTIONS MTC-7 < SERVICE INFORMATION > C D E F G H I K L M A B MTC N O P MR18DE - TYPE 2 WARNING: Make sure all refrigerant is discharged into the recycling equipment and the pressure in the system is less than atmospheric pressure. Then gradually loosen the discharge side hose fitting and remove it. CAUTION: The new and former refrigerant connections use different O-ring configurations. Do not confuse O- rings since they are not interchangeable. If a wrong O-ring is installed, refrigerant will leak at, or around, the connection. O-Ring Specifications* * : Always check with the parts department for the latest parts information. CAUTION: When replacing or cleaning refrigerant cycle components, observe the following. • When the compressor is removed, store it in the same position as it is when installed on the vehicle. Doing so will cause oil to enter the low-pressure chamber. • When connecting tubes, always use a torque wrench and a back-up wrench. • After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

Do not remove the seal caps of pipes and other components until just before required for con- nection. • Allow components stored in cool areas to warm to working area temperature before removing seal caps. This prevents condensation from forming inside A/C components. • Thoroughly remove moisture from the refrigeration system before charging the refrigerant. • Always replace used O-rings. • When connecting tube, apply the specified A/C oil to circle of the O-rings. Be careful not to apply oil to threaded portion. Refer to MTC-93, " Oil". • O-ring must be closely attached to dented portion of tube. • When replacing the O-ring, be careful not to damage O-ring and tube. • Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that the O-ring is installed to tube correctly. • After connecting line, perform leak test and make sure that there is no leakage from connections. When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then tighten connections of seal seat to the specified torque. Precaution for Service of Compressor INFOID:0000000007329060 • Plug all openings to prevent moisture and foreign matter from entering. • When the compressor is removed, store it in the same position as it is when mounted on the car. • When replacing or repairing compressor, follow “Maintenance of Oil Quantity in Compressor” exactly. Refer to MTC-17, " Maintenance of Oil Quantity in Compressor". • Keep friction surfaces between clutch and pulley clean. If the surface is contaminated, with oil, wipe it off by using a clean waste cloth moistened with thinner. • After compressor service operation, turn the compressor shaft by hand more than five turns in both directions. This will equally distribute oil inside the compressor. After the compressor is installed, let the engine idle and operate the compressor for one hour. • After replacing the compressor magnet clutch, apply voltage to the new one and check for usual operation. Precaution for Service Equipment INFOID:0000000007329061 RECOVERY/RECYCLING EQUIPMENT Be certain to follow the manufacturer’s instructions for machine operation and machine maintenance.

OK WJIA1994E Revision: July 2011 2012 Versa PRECAUTIONS MTC-9 < SERVICE INFORMATION > C D E F G H I K L M A B MTC N O P VACUUM PUMP The oil contained inside the vacuum pump is not compatible with the specified oil for HFC-134a (R-134a) A/C systems. The vent side of the vacuum pump is exposed to atmospheric pressure. So the vac- uum pump oil may migrate out of the pump into the service hose. This is possible when the pump is switched off after evacuation (vac- uuming) and hose is connected to it. To prevent this migration, use a manual valve placed near the hose- to-pump connection, as follows. • Usually vacuum pumps have a manual isolator valve as part of the pump. Close this valve to isolate the service hose from the pump. • For pumps without an isolator, use a hose equipped with a manual shut-off valve near the pump end. Close the valve to isolate the hose from the pump. • If the hose has an automatic shut-off valve, disconnect the hose from the pump. As long as the hose is connected, the valve is open and lubricating oil may migrate. Some one-way valves open when vacuum is applied and close under a no vacuum condition. Such valves may restrict the pump’s ability to pull a deep vacuum and are not recommended. MANIFOLD GAUGE SET Be certain that the gauge face indicates HFC-134a or R-134a. Be sure the gauge set has 1/2″-16 ACME threaded connections for ser- vice hoses. Confirm the set has been used only with refrigerant HFC-134a (R-134a) and specified oils. SERVICE HOSES Be certain that the service hoses display the markings described (colored hose with black stripe). All hoses must include positive shut- off devices (either manual or automatic) near the end of the hoses opposite the manifold gauge. SERVICE COUPLERS RHA270DA SHA533D RHA272D Revision: July 2011 2012 Versa MTC-10 < SERVICE INFORMATION > PRECAUTIONS Never attempt to connect HFC-134a (R-134a) service couplers to a CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will not properly connect to the CFC-12 (R-12) system. However, if an improper connection is attempted, discharging and contamination may occur. REFRIGERANT WEIGHT SCALE Verify that no refrigerant other than HFC-134a (R-134a) and speci- fied oils have been used with the scale. If the scale controls refriger- ant flow electronically, the hose fitting must be 1/2″-16 ACME. CHARGING CYLINDER Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder’s top valve when filling the cylinder with refrigerant. Also, the accuracy of the cylinder is generally less than that of an electronic scale or of quality recycle/recharge equipment. Precaution for Leak Detection Dye INFOID:0000000007329062 • The A/C system contains a fluorescent leak detection dye used for locating refrigerant leaks. An ultraviolet (UV) lamp is required to illuminate the dye when inspecting for leaks. • Always wear fluorescence enhancing UV safety goggles to protect your eyes and enhance the visibility of the fluorescent dye. • The fluorescent dye leak detector is not a replacement for an electronic refrigerant leak detector. The fluo- rescent dye leak detector should be used in conjunction with an electronic refrigerant leak detector to pin- point refrigerant leaks. • For your safety and your customer’s satisfaction, read and follow all manufacture’s operating instructions and precautions prior to performing the work. • A compressor shaft seal should not be repaired because of dye seepage. The compressor shaft seal should only be repaired after confirming the leak with an electronic refrigerant leak detector. • Always remove any remaining dye from the leak area after repairs are complete to avoid a misdiagnosis dur- ing a future service. • Do not allow dye to come into contact with painted body panels or interior components. If dye is spilled, clean immediately with the approved dye cleaner. Fluorescent dye left on a surface for an extended period of time cannot be removed. • Do not spray the fluorescent dye cleaning agent on hot surfaces (engine exhaust manifold, etc.). • Do not use more than one refrigerant dye bottle (1/4 ounce /7.4 cc) per A/C system. • Leak detection dyes for HFC-134a (R-134a) and CFC-12 (R-12) A/C systems are different. Do not use HFC- 134a (R-134a) leak detection dye in CFC-12 (R-12) A/C system or CFC-12 (R-12) leak detector dye in HFC- 134a (R-134a) A/C system or A/C system damage may result. • The fluorescent properties of the dye will remain for over three (3) years unless a compressor malfunction occurs. IDENTIFICATION LABEL FOR VEHICLE Vehicles with factory installed fluorescent dye have an identification label on the front underside of the hood. NOTE: • Vehicles with factory installed fluorescent dye have a green label. • Vehicles without factory installed fluorescent dye have a blue label.
