Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air conditioning
system
in your vehicle needs refrigerant, be sure the proper refrigerant is
used. If you’re not sure, ask your GM dealer. For additional information, see
your “Warranty and Owner Assistance Information” booklet.
