    Simple Advanced Parking Guidance System
    Power Door Lock Control System
    Pre-crash Safety System
    Adaptive High Beam System

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

  3. ALWAYS WEAR EYE PROTECTION

  4. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN YOUR EYES OR ON YOUR SKIN

    A003P74

    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.

  5. NEVER HEAT CONTAINER OR EXPOSE CONTAINER TO AN OPEN FLAME

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

  7. DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM

    If there is not enough refrigerant in the air conditioning system, oil lubrication will be insufficient and the compressor may be damaged.

    Necessary care should be taken to avoid this.

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

    A003OWXC06
    *a Wrong
    *b Okay

    Open and close only the low pressure valve.

    If the high pressure valve is opened, refrigerant will flow in the reverse direction causing the charging cylinder to rupture.

  9. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT

    If the system is overcharged with refrigerant, it causes problems such as insufficient cooling, poor fuel economy, engine overheating, etc.

  10. DO NOT OPERATE ENGINE AND COMPRESSOR WITH NO REFRIGERANT

    CAUTION:

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

  11. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

    This vehicle is equipped with a Supplemental Restraint System (SRS). Failure to carry out service operations 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.

  12. GENERAL PRECAUTION

    While using the auxiliary battery during inspection, do not bring the positive (+) and negative (-) tester probes too close to each other as a short circuit may occur.

  13. PRECAUTIONS WHEN WORKING


    1. When working on a vehicle with a remote air conditioning system, there are certain risks associated with the operation of the system.

      Risks
      The electrical fan and other items in the engine compartment may operate resulting in various hazards.

      Tech Tips

      Make sure to keep any smartphones or electrical key transmitter sub-assemblies, which are registered to the vehicle, in a safe place where they will not be operated accidentally.

    2. As the air conditioning system may operate unexpectedly, do not perform repairs while a charging connector is connected to the vehicle.
