Nissan environmental program
The release of refrigerants into the atmosphere is prohibited in many countries and regions. Refrigerant HFC-134a (R-134a), used in your car, does not destroy the ozone layer of the Earth's atmosphere, but its release into the atmosphere can affect global climate warming processes on Earth. Nissan recommends that you refill and dispose of the refrigerant properly. For air conditioning service, contact an authorized Nissan dealer.
