PERIODIC MAINTENANCE
(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace the drive belts if found
damaged or if the auto belt tensioner reading reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, go to the FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.
(5) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and intervals are
required.

(1) If towing a trailer, or using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every
30,000 miles
(48,000 km) or 24 months. Using automatic transmission fluid other than Ge nuine NISSAN Matic S ATF or Matic J ATF will cause
deterioration in drive ability and automatic transmission durability, and may damage the automatic transmission, which is not
covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” under the “General maintenance” heading earlier in this section.
