AIR CONDITIONING – AIR CONDITIONING SYSTEM AC–1 AIR CONDITIONING SYSTEM PRECAUTION NOTICE: Because the compressor operates at high voltages, wear electric insulated gloves and pull out the service plug grip to cut the high-voltage circuit before inspection HINT: When the power switch on (IG) after the 12 volt battery is reconnected, the indicator light on the switch may flash and a motor sound may be heard This does not indicate a malfunction DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME ALWAYS WEAR EYE PROTECTION Charging Cylinder AC02810E02 AC02811 Wrong LO HI Okay LO HI N011084E03 BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN YOUR EYES OR ON YOUR SKIN If liquid refrigerant gets in your eyes or on your skin: (a) Wash the area with lots of cold water CAUTION: Do not rub your eyes or skin (b) Apply clean petroleum jelly to the skin (c) Go immediately to a hospital or see a physician for professional treatment NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN FLAME BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM If there is not enough refrigerant in the A/C system, oil lubrication will be insufficient and the compressor may be damaged Necessary care should be taken to avoid this DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING Open and close only the low pressure valve If the high pressure valve is opened, refrigerant flows in the reverse direction causing the charging cylinder to rupture BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT If refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy, engine overheating, etc AC AC–2 AIR CONDITIONING – AIR CONDITIONING SYSTEM NOTICE FOR HYBRID SYSTEM ACTIVATION When the warning light is illuminated or the HV battery has been disconnected and reconnected, turning the power switch on (READY) may not start the system on the first try If so, turn the power switch off and reattempt to turn the power switch on (READY) 10 PRECAUTIONS TO BE OBSERVED WHILE SERVICING NOTICE: • Only use ND-OIL11 for the electric inverter compressor of the air conditioning system Using other A/C oils may be dangerous, as they may conduct electricity • Electrical insulation performance may decrease significantly if even a small amount of oil other than ND-OIL11 is used (or enters) in the refrigeration cycle, causing a DTC to be output • If other oil is accidentally used and a DTC is output, collect the compressor oil in the compressor and replace it with ND-OIL11 to increase the ND-OIL11 ratio amount • Replace the main components (evaporator, condenser, and compressor) if a large amount of oil other than ND-OIL11 enters the system Failing to so may cause electrical insulation performance to remain low, causing a DTC to be output CAUTION: Always use electric insulating gloves and remove the service plug grip before beginning inspection, as inspection of the air conditioning system requires disconnecting high voltage connectors (See page AC-88) 11 SUPPLEMENTAL RESTRAINT SYSTEM (SRS) (a) This vehicle is equipped with an SRS (Supplemental Restraint System) such as the driver, front passenger, side, and curtain shield airbags Failure to carry out service operation in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notices (See page RS-1) 12 NOTICE FOR INITIALIZATION NOTICE: When disconnecting the negative (-) battery terminal, initialize the following systems after the terminal is reconnected AC System Name See procedure SFI System (See page IN-43) AIR CONDITIONING – AIR CONDITIONING SYSTEM AC–3 13 GENERAL PRECAUTION (a) While using the battery during inspection, not bring the positive and negative tester probes too close to each other as a short circuit may occur AC AC–4 AIR CONDITIONING – AIR CONDITIONING SYSTEM PARTS LOCATION ELECTRIC INVERTER COMPRESSOR (COMPRESSOR WITH MOTOR ASSEMBLY) ENGINE ROOM NO RELAY BLOCK INVERTER WITH CONVERTER ASSEMBLY -
