(1) After 60,000 miles (96,000 km) or 48 months, inspect every 15,000 miles (24,000 km) or 12 months. Replace drive belts if da maged.
(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) 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 inter vals are

*1: For further details, refer to MA-12, "SAE Viscosity Number" .
*2: 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 transmission, which is not covered by the NISSAN new vehicle limited warr anty.
*3: For Canada, NISSAN Automatic Transmission Fluid (ATF), DEXRON
TM III or MERCONTM or equivalent ATF may also be used.
*4: Available in mainland U.S.A. through your NISSAN dealer.
*5: For further details, see “Air conditioner specification label ”.
*6: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0 ° C (32° F).
*7: DEXRON
TM III, MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact a NISSAN
dealership for more information regarding suitable fluids, including recommended brand(s) of DEXRONTM III or MERCONTM Automatic
Transmission Fluid.
*8: For improved vehicle performance, NISSAN recommends the use of unleaded premium gasoline with an octane rating of at least 91
AKI (RON 96). For further details, refer to GI-5, "

CAUTION:
Clean the drain plug and install with a new washer.
5. Refill the engine with new specified engine oil.
CAUTION:
The refill capacity depends on the oil temperature and drain time. Use the “Refill oil capacity” val-
ues as a reference and check the oil level using the dipstick when filling the engine with oil.
6. Warm up the engine and check the area around the drain plug and oil filter for any oil leaks.
7. Stop the engine and wait for more than 10 minutes.
8. Check the oil level using the dipstick as shown. Add oil as nec- essary and install the oil filler cap.
