The air conditioner system in your NISSAN vehicle must be charged with the refrigerant HFC-134a (R-134a) and Genuine NISSAN A/C System Oil Type ND-OIL8 or the exact equivalents.
CAUTION
The use of any other refrigerant or oil may cause severe damage to the air conditioning system and may require the replacement of all air conditioner system components.
The refrigerant HFC-134a (R-134a) in your NISSAN vehicle does not harm the earth's ozone layer. Although this refrigerant does not affect the earth's atmosphere, certain government regulations require the recovery and recycling of any refrigerant during automotive air conditioner system service. A NISSAN dealer has the trained technicians and equipment needed to recover and recycle your air conditioner system refrigerant.
It is recommended that you visit a NISSAN dealer when servicing your air conditioner system.
