AIR CONDITIONING SYSTEM (for Manual Air Conditioning System) - PRECAUTION
| 1.PRECAUTIONS WHEN USING THE INTELLIGENT TESTER |
When using the intelligent tester to troubleshoot the CAN communication line or LIN communication line:
Connect the intelligent tester to the vehicle, and turn a courtesy light switch on and off at 1.5 second intervals until communication between the intelligent tester and vehicle begins.
After all DTCs are cleared, check if the trouble occurs again 6 seconds after the ignition switch is turned to ON.
| 2.IF ANY OF FOLLOWING CONDITIONS ARE MET, KEEP ENGINE IDLING (ENGINE SPEED AT LESS THAN 2000 RPM) WITH AIR CONDITIONING SWITCH ON FOR AT LEAST 2 MINUTES |
Refrigerant gas has been refilled or parts of the air conditioning system have been replaced.
The engine has not been started for a long time.
- If the engine speed is more than 2000 rpm, the cooler compressor assembly may be damaged.
| 3.DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME |

| 4.ALWAYS WEAR EYE PROTECTION |
| 5.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.
- 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.
| 6.NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN FLAME |
| 7.BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT |
| 8.DO NOT OPERATE COMPRESSOR WITH INSUFFICIENT REFRIGERANT IN REFRIGERANT SYSTEM |
If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and compressor burnout may occur. Necessary care should be taken to avoid this.
| 9.DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING |
Open and close only the low pressure valve. Opening and closing the high pressure valve could cause the charging cylinder to rupture.

| 10.BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT |
If the refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy and engine overheating.
| 11.DO NOT OPERATE ENGINE AND COOLER COMPRESSOR ASSEMBLY WITHOUT REFRIGERANT |
- This may damage the inside of the cooler compressor assembly.
