(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.
(5) If valve noise increases, inspect valve clearance.
* Maintenance items and intervals with “*” are recommended by INFINITI 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.
CHASSIS AND BODY MAINTENANCE
Abbreviations: R = Replace. I = Inspect. Correct or replace if necessary.
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.MAINTENANCE OPERATIONMAINTENANCE INTERVAL
