  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.


4.NEVER HEAT CONTAINER OR EXPOSE THE CONTAINER 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

  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.


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

  1. When disconnecting the negative (-) battery terminal, initialize the following systems after the terminal is reconnected.

    System Name
    		See procedure
    Parking Assist Monitor System
    		(Click here)
    Power Window Control System

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 A/C system is turned on or off.

11.SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

  1. This vehicle is equipped with an SRS (Supplemental Restraint System) such as the driver, front passenger, side, and curtain shield airbags. Failure to carry out service operation 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 (Click here).


12.GENERAL PRECAUTION

  1. 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.
