Your engine was filled with a high-quality engine oil when it was built. You do not have to change the oil before the first recommended change interval. Oil and filter change intervals depend upon how you use your vehicle. Operation under the following conditions may require more frequent oil and filter changes: ● repeated short distance driving at cold outside temperatures ● driving in dusty conditions ● extensive idling ● towing a trailer ● stop and go commuting Refer to the NISSAN Service and Maintenance Guide for the maintenance schedule. AIR CONDITIONER SYSTEM REFRIGERANT AND OIL RECOMMENDATIONS The air conditioner system in your NISSAN vehicle must be charged with the refrigerant HFC-134a (R-134a) and the oil, NISSAN A/C system oil Type R or the exact equivalents. CAUTION The use of any other refrigerant or oil 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. A NISSAN dealer has the trained technicians and equipment needed to recover and recycle your air conditioner system refrigerant. Contact a NISSAN dealer when servicing your air conditioner system.
