  4. MAIN FEATURES


    1. The air conditioning system has the following features:

      High Performance

      • Neural network control is used so passengers can finely control the air conditioning for maximum comfort.

      • Pollen removal mode control is used to remove pollen in the area around the upper part of the bodies of the driver and front passenger.

      • The blower control has 7 levels in manual mode and 31 levels in auto mode for more precise control.
      Lightweight A bus connector with a built-in communication/driver IC is used in a lightweight wire harness design to allow a reduced number of wires. The use of this type of connector means that pulse pattern type servo motors are used.
      Compact A blower motor with a built-in blower motor controller is used to achieve a compact construction.
      Others

      The following parts are used to ensure high performance while realizing a compact and lightweight construction.


      • ES27 type electric inverter compressor

      • Semi-center location air conditioning unit

      • Revolutionary super-slim Structure (RS) evaporator

      • Straight Flow Aluminum (SFA)-II heater radiator sub-assembly

      • Multi-Flow (MF)-IV sub-cool condenser

  5. PRECAUTION


    1. Precaution for Refrigerant HFO-1234yf


      1. The parts used in the refrigerant cycle, the compressor oil, etc. of a HFO-1234yf system are not compatible with a conventional HFC-134a system.

      2. Always use HFO-1234yf as the refrigerant.

        Note


        • Do not charge the system with refrigerant near open flames, as HFO-1234yf is combustible.

        • When charging the system with refrigerant, make sure the area is well ventilated (especially be careful in areas where the gas can easily accumulate such as under lifts and in garage pits, as the gas is heavier than air).

        • Follow any local regulations regarding combustible gases.

        • Be sure to use a refrigerant recovery unit that is compatible with HFO-1234yf systems.

        Tech Tips

        The shape of the service port for refrigerant charging has an exclusive design conforming to international standards for HFO-1234yf to prevent improper refrigerant charging.

    2. Compressor Oil


      1. Always use ND-OIL 11 as the compressor oil.

      2. When parts of the air conditioning system are removed, quickly block off any areas that are exposed to the outside air with plugs, vinyl tape, etc., as the oil used for HFO-1234yf systems absorbs moisture easily.

      3. Do not allow the compressor oil to spray, as the oil used for HFO-1234yf systems has harmful effects on acrylic resins.
