AIR CONDITIONER SYSTEM REFRIGERANT AND LUBRICANT RECOMMENDATIONS The air conditioner system in this NISSAN vehicle must be charged with the refrigerant HFC-134a (R-134a) and the lubricant, NISSAN A/C system lubricant Type R or the exact equivalents. CAUTION The use of any other refrigerant or lubricant will cause severe damage to the air conditioning system and will 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. An authorized NISSAN dealer has the trained technicians and equipment needed to recover and recycle your air conditioner system refrigerant. Contact an authorized NISSAN dealer when servicing your air conditioner system.
