NOTE:
(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 (only for VK45DE engine) reaches the maximum limit.
(2) If operating mainly in dusty conditions, more frequent maintenance may be required.
(3) Maintenance-free item. For service procedures, refer to FL section.
(4) After 60,000 miles (96,000 km) or 48 months, replace every 30,000 miles (48,000 km) or 24 months.

NOTE:
(1) If towing a trailer, using a camper or a car-top carrier, or driving on rough or muddy roads, change (not just inspect) fluid (A/T, trans-
fer)/oil at every 30,000 miles (48,000 km) or 24 months. Using automatic transmission fluid other than Genuine NISSAN Matic J
ATF will cause deterioration in driveability and automatic transmission durability, and may damage the automatic transmis-
sion, 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.
