2. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED AREA OR NEAR AN OPEN FLAME

Charging Cylinder |
3. ALWAYS WEAR EYE PROTECTION
4. 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:
(a) Wash the area with lots of cold water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a hospital or see a physician for professional treatment.
5. PRECAUTIONS FOR REFRIGERANT HFO-1234yf [R1234yf] (for HFO-1234yf (R1234yf))
(a) Refer to the precaution for refrigerant HFO-1234yf [R1234yf] (See page
).
6. NEVER HEAT CONTAINER OR EXPOSE THE CONTAINER TO AN OPEN FLAME
7. BE CAREFUL NOT TO DROP CONTAINER OR APPLY PHYSICAL SHOCKS TO IT
8. 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.
9. DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
(a) Open and close only the low pressure valve.
If the high pressure valve is opened, refrigerant will flow in the reverse direction causing the charging cylinder to rupture.

*b |
Okay |
10. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH REFRIGERANT
If the system is overcharged with refrigerant, it causes problems such as insufficient cooling, poor fuel economy, engine overheating, etc.
11. 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.
12. SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(a) This vehicle is equipped with a Supplemental Restraint System (SRS) such
as the driver, front passenger, side, and curtain shield airbags. Failure to carry
out service operations 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 (See page ).
13. GENERAL PRECAUTION
(a) 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.
