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 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) First replacement interval is 105,000 miles (168,000 km) or 84 months. After first replacement, replace every 75,000 miles (120,000
km) or 60 months. Use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent with proper mixture ratio of 50% anti-
freeze and 50% demineralized or distilled water. Mixing any other type of coolant or the use of non-distilled water will reduce the life
expectancy of the factory-fill coolant.

(5) Periodic maintenance is not required. However, 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.

*1: For further details, see “Engine Oil Recommendation”.

*2: Using automatic transmission fluid other than Genuine NISSAN Matic S ATF will cause deterioration in driveability and automatic
transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited warranty.

*3: DEXRON™ VI type ATF may also be used.

*4: Available in mainland U.S.A. through an INFINITI dealer.

*5: Using transfer fluid other than Genuine NISSAN Transfer Fluid will damage the transfer, which is not covered by the INFINITI new
vehicle limited warranty. See an INFINITI retailer for recommended transfer fluid.

*6: For hot climates, Viscosity SAE 90 is suitable for ambient temperatures above 0

F)

*7: See an INFINITI dealer for service for synthetic oil.

*8: Using Hydraulic Suspension fluid other than Genuine NISSAN Hydraulic Suspension fluid will damage the Hydraulic Suspension,
which is not covered by the INFINITI new vehicle limited warranty. See an INFINITI retailer for recommended hydraulic suspension fluid.

*9: The fluid capacity is the reference value. 

Engine Oil Recommendation

INFOID:0000000006287732

NISSAN recommends the use of an energy conserving oil in order to improve fuel economy.
Select only engine oils that meet the American Petroleum Institute (API) certification and International Lubri-
cant Standardization and Approval Committee (ILSAC) certification and SAE viscosity standard. These oils
have the API certification mark on the front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.
