PRECAUTION

Note. Because the compressor operates at high voltages, wear electric insulated gloves and pull out the service plug to cut the high-voltage circuit before inspection.

1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME.
2. ALWAYS WEAR EYE PROTECTION
3. 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: Wash the area with lots of cold water. CAUTION: Do not rub your eyes or skin. Apply clean petroleum jelly to the skin. Go immediately to a hospital or see a physician for professional treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN FLAME
5. BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT
6. 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.
7. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING Open and close only the low pressure valve. If the high pressure values are opened, refrigerant flows in the reverse direction causing the charging cylinder to rupture. If the high pressure valve is opened, refrigerant flows in the reverse direction causing the charging cylinder to rupture.
8. 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.
9. NOTICE FOR INITIALIZATION: When disconnecting the negative (-) battery terminal, initialize the following systems after the terminal is reconnected. SYSTEM INITIALIZATION TABLE System Name See procedure Lighting System (Adaptive Front-Lighting System) «INITIALIZATION»(ref-236032-S32462476002006062900000) Power Window Control System «INITIALIZATION»(ref-236041-S15540293112006062900000) Power Back Door System «INITIALIZATION»(ref-236020-S16519146372006062900000) Sliding roof system «INITIALIZATION»(ref-236021-S29807869632006062900000) (for standard) and «INITIALIZATION»(ref-236021-S01691602862006062900000) (for multi panel roof)
10. GENERAL PRECAUTION While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.

1. General The air conditioning system has the following features: A compact, lightweight, and highly efficient electrical water pump is used in order to ensure the proper heater performance while the engine is stopped. A left / right independent temperature control and neural network control have been adopted to make air conditioner control available to suit the perception of the persons in the driver seat and in the passenger seat. Automatic air conditioner is standard in all models. A left/right independent temperature control and neural network control have been adopted to make air conditioner control available to suit the perception of the persons in the driver seat and in the passenger seat. Automatic air conditioner is standard in all models. A semi-center location air conditioner unit, in which the evaporator and heater core are placed in the vehicle's longitudinal direction, is used. A compact, lightweight, and highly efficient straight flow (full-path flow) aluminum heater core is used. A revolutionary slim structure evaporator is used. A humidity sensor function has been added to the room temperature sensor in order to optimize the amount of dehumidification effort during the operation of the air conditioning system. A deodorizing function that eliminates the exhaust gas smell that enters the cabin from the outside has been added to the conventional clean air filter. The air conditioning ECU is equipped with a self-diagnosis function. If there is a malfunction in the system, it stores the DTCs (Diagnostic Trouble Codes) in its memory.
2. Mode Position and Damper Operation Function of Main Damper MAIN DAMPER FUNCTION Control Damper Control Position Damper Position Operation Air Inlet Control Damper FRESH A Brings in fresh air. RECIRCULATION B Recirculates internal air. Air Mix Control Damper (Left / Right Independent Control) MAX COLD - MAX HOT TEMP. SETTING (18°C (65°F) - 32°C (85°F)) C - D - E Varies the mixture ratio of the cool air and the warm air in order to regulate the temperature continuously from HOT to COLD.
3. Air Outlets and Air Volume Rations The size of the circle "O" indicates the proportion of airflow volume.

CUSTOMIZE PARAMETERS

HINT

The followings are the possible items to be customized.

Note. After confirming whether the items of the customer's request is applicable or not for the customized items, perform the customize operation. Be sure to record the current value before customizing. In case of performing the troubleshooting, pay attention as there is a possibility that the function is OFF by customizing. (Example: In case of the symptom in which "The wireless operation does not function", check that the wireless operation is not OFF by customizing, then perform the troubleshooting.)
