AIR CONDITIONING SYSTEM(for Automatic Air Conditioning System) PRECAUTION


  1. IGNITION SWITCH EXPRESSIONS


    1. The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this section.

      Expression Ignition Switch (Position) Engine Switch (Condition)
      Ignition switch off LOCK Off
      Ignition switch ON ON On (IG)
      Ignition switch ACC ACC On (ACC)
      Engine Start START Start

  2. IF ANY OF FOLLOWING CONDITIONS ARE MET, KEEP ENGINE IDLING WITH A/C ON (ENGINE SPEED AT LESS THAN 2000 RPM) FOR AT LEAST 1 MINUTE:


    • Refrigerant gas has been refilled or A/C parts have been replaced.

    • A long time has elapsed since engine was stopped.

    Note

    If the engine speed exceeds 2000 rpm, the A/C compressor may be damaged.

  3. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME

  4. ALWAYS WEAR EYE PROTECTION

  5. 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:


    1. Wash the area with lots of cold water.

      CAUTION:

      Do not rub your eyes or skin.

    2. Apply clean petroleum jelly to the skin.

    3. Go immediately to a hospital or see a physician for professional treatment.

  7. NEVER HEAT CONTAINER OR EXPOSE CONTAINER TO OPEN FLAME

  8. BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT

  9. 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.

  10. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING

    *b Okay

    1. 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.

  11. 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.

  12. DO NOT OPERATE COMPRESSOR WITHOUT REFRIGERANT

    CAUTION:

    Doing so may damage inside the compressor because the compressor parts always move regardless of whether the A/C system is turned on or off.
