Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT BELT PRE-TENSIONER” BJS000AI The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the SRS and SB section of this Service Manual. WARNING: l 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 per- formed by an authorized NISSAN/INFINITI dealer. l Improper maintenance, including incorrect removal and installation of the SRS, can lead to per- sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air Bag Module, see the SRS section. l 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 harness connectors. Precautions for Procedures without Cowl Top Cover BJS000AJ When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc. PIIB3706J Precautions for Working with HFC-134a (R-134a) BJS000AK WARNING: l Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) compo- nents. If lubricant other than that specified is used, compressor malfunction is likely to occur. The specified HFC-134a (R-134a) lubricant rapidly absorbs moisture from the atmosphere. The fol- lowing handling precautions must be observed: l 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 possi- ble to minimize the entry of moisture into system. – Only use the specified lubricant from a sealed container. Immediately reseal containers of lubri- cant. Without proper sealing, lubricant will become moisture saturated and should not be used. – Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refriger- ant. If accidental system discharge occurs, ventilate work area before resuming service. Addi- tional – health and safety information may be obtained from refrigerant and lubricant manufacturers. – Do not allow lubricant (Nissan A/C System Oil Type R) to come in contact with styrofoam parts. Damage may result. General Refrigerant Precautions BJS000AL WARNING: l Do not release refrigerant into the air. Use approved recovery/recycling equipment to capture the refrigerant every time an air conditioning system is discharged. ATC-4 PRECAUTIONS Always wear eye and hand protection (goggles and gloves) when working with any refrigerant or air conditioning system. l A C. l 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. l Do not intentionally drop, puncture, or incinerate refrigerant containers. l Keep refrigerant away from open flames: poisonous gas will be produced if refrigerant burns. l Refrigerant will displace oxygen, therefore be certain to work in well ventilated areas to prevent suffocation. l Do not pressure test or leak test HFC-134a (R-134a) service equipment and/or vehicle air condi- tioning 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 refriger- ant manufacturers. Lubricant Precautions BJS000AM l Use only specified lubricant for the HFC-134a (R-134a) A/C system and HFC-134a (R-134a) components. If lubricant other than that specified is used, compressor malfunction is likely to occur. l The specified HFC-134a (R-134a) lubricant 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 lubricant from a sealed container. Immediately reseal containers of lubricant. With- out proper sealing, lubricant will become moisture saturated and should not be used. l Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and throat. Use only approved recovery/recycling equipment to discharge HFC-134a (R-134a) refrigerant. If acciden- tal system discharge occurs, ventilate work area before resuming service. Additional health and safety information may be obtained from refrigerant and lubricant manufacturers. l Do not allow lubricant (Nissan A/C System Oil Type R) to come in contact with styrofoam parts. Damage may result. Precautions for Refrigerant Connection BJS000AN A new type refrigerant connection has been introduced to all refrigerant lines except the following location. l Expansion valve to evaporator l Refrigerant pressure sensor to condenser FEATURES OF NEW TYPE REFRIGERANT CONNECTION l Do not store or heat refrigerant containers above 52 ° l B C D E F G H I ATC K L M 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 characteristics. ATC-5 [ Pobierz całość w formacie PDF ] |
