ALWAYS WEAR SAFETY GLASSES FOR EYE PROTECTION
AVOID YOUR EYES AND SKIN TO CONTACT WITH LIQUID REFRIGERANT
If you get the liquid refrigerant in your eyes or on your skin:
1. Wash out 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 physician or hospital for professional treatment.

NEVER HEAT CONTAINER OR EXPOSE IT TO NAKED FLAME
DO NOT DROP CONTAINER NOR APPLY PHYSICAL SHOCKS TO IT.
DO NOT OPERATE COMPRESSOR WITHOUT ENOUGH REFRIGERANT IN REFRIGERANT SYSTEM
If there is not enough refrigerant in the refrigerant system, oil lubrication will be insufficient and compressor burnout may occur. To avoid this, always keep enough refrigerant in the refrigerant system.
DO NOT OPEN HIGH PRESSURE MANIFOLD VALVE WHILE COMPRESSOR IS OPERATING
If the high pressure valves opened, refrigerant flows in the reverse direction and could cause the charging cylinder to rupture, so open and close the only low pressure valve.

DO NOT OVERCHARGE REFRIGERANT SYSTEM WITH REFRIGERANT
If refrigerant is overcharged, it causes problems such as insufficient cooling, poor fuel economy, engine overheating etc.
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
The LAND CRUISER is equipped with SRS (Supplemental Restraint System) such as the driver airbag and the front passenger airbag. 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 in SUPPLEMENTAL RESTRAINT SYSTEM .
