Environmental Information
Since roughly 1992, the air conditioning systems of newly manufactured cars have been successively converted to refrigerant R134a. This refrigerant does not contain chlorine and does not deplete the ozone layer.
Until roughly 1992, refrigerant R12 was used for air conditioning systems. Due to its chlorine atoms, this CFC has a high potential for depleting the ozone layer as well as a tendency to increase the greenhouse effect.
Conversion programs are available for old existing systems filled with the ozone-depleting substance R12. Refer to Repair Information for A/C Systems with Refrigerant R12 (this repair information is only available in hard copy).
For environmental protection reasons, refrigerants must not be released into the atmosphere. For laws and regulations. Refer to LAWS AND REGULATIONS .
