Vehicle Damage Warnings

CAUTIONARY POINTS FOR MAINTENANCE

REFRIGERANT-134a (R-134a)

Outline
R-12 and other fluorocarbons now used in air conditioners can destroy the ozone layer in the stratosphere. The result is an increase in hazardous ultraviolet rays which over time can adversely affect both human health and the biosphere. Because of this concern, Mazda has chosen to use R-134a (HFC-1 34a), a hydrofluorocarbon-based refrigerant that does not deplete the ozone layer, in this vehicle.

R-12 and R-134a are not interchangeable; system parts and system service tools also differ. The table below compares the two systems.









SERVICE WARNINGS
Using/Handling Unapproved Refrigerant
Using a flammable refrigerant, such as OZ-12, in this vehicle is dangerous. In an accident, the refrigerant may catch fire, resulting in serious injury or death. When servicing this vehicle, use only R-134a.

Checking for system leaks on a vehicle that has been serviced with flammable refrigerant, such as OZ-12, is dangerous. Conventional leak detectors use an electronically generated arc which can ignite the refrigerant, causing serious injury or death. If a flammable refrigerant has been used to service the system, or if you suspect a flammable refrigerant may have been used, contact the local fire marshal or EPA office for information on handling the refrigerant.
