Air conditioners on Nissan vehicles are charged with a new type of refrigerant designed to protect the environment.
Such a refrigerant is harmless to the ozone layer of the Earth.
However, it should be remembered that the refrigerant can contribute to the process of global warming of the Earth's climate.
Maintenance of the Nissan air conditioner requires special filling equipment and lubricating oils. The use of unsuitable refrigerants or lubricating oils will result in failure of the entire air conditioning system. See section "Recommendations for refrigerant and air conditioner lubrication".
It is recommended to have your Nissan environmentally friendly air conditioner serviced by your Nissan dealer.
