AIR CONDITIONING SYSTEM REFRIGERANT AND LUBRICANT RECOMMENDATIONS The air conditioning 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 Use of any other refrigerant or lubricant will cause severe damage and you will need to replace your vehicle's entire air conditioning system. 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 conditioning system service. Your NISSAN dealer has the trained technicians and equipment needed to recover and recycle your air conditioning system refrigerant. Contact your NISSAN dealer when servicing your air conditioning system. 9-8 ATI0510 ● 80W-90 is preferable for ambient temperatures below 104°F (40°C).
