  3. MAIN FEATURES


    1. The air conditioning system has the following features:

      Item Outline
      High Performance

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

      • A pollen removal type clean air filter is used.

      • The blower control has 7 levels in manual mode and 31 levels in auto mode for more precise control.

      • The Positive Temperature Coefficient (PTC) heater control is used. This system contains a PTC heater (quick hater assembly) that heats the air that has passed through the heater radiator unit sub-assembly to ensure proper heater performance.*
      Lightweight A bus connector (air conditioning harness assembly) with a built-in IC is used in a lightweight wire harness design with a reduced number of wires. The use of this connector means that pulse pattern type servo motors are used.
      Compact

      • A semi-center location air conditioning unit in which the No. 1 cooler evaporator sub-assembly, heater radiator unit sub-assembly and PTC heater (quick hater assembly)* are placed in the vehicle's longitudinal direction is used.

      • A blower motor with a built-in blower motor controller is used in a compact construction.
      Others

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


        • Revolutionary super-Slim structure (RS) type No. 1 cooler evaporator sub-assembly

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

        • Global Inner-fin type cooler condenser assembly

        • ES14 type electric inverter compressor (compressor with motor assembly)

      • *: Cold area specification models

  4. PRECAUTION


    1. Precaution for Refrigerant HFO-1234yf


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

        CAUTION:


        • 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.
