PERIODIC MAINTENANCE
Introduction of Periodic MaintenanceINFOID:0000000006287729
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage/time intervals.
Schedule 1INFOID:0000000006287730

Abbreviations: R = Replace. I = Inspec t. Correct or replace if necessary. [ ]: At the mileage intervals only
Schedule 1Follow Periodic Maintenance Schedule 1 if the driving habits frequently include
one or more of the following driving conditions:
 Repeated short trips of less than 5 miles (8 km).
 Repeated short trips of less than 10 miles (16 km) with outside temperatures
remaining below freezing.
 Operating in hot weather in stop-and-go “rush hour” traffic.
 Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
 Driving in dusty conditions.
 Driving on rough, muddy, or salt spread roads.
 Towing a trailer, using a camper or a car-top carrier. Emission Control Sys-

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 i
f 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 Genu ine NISSAN Long Life Antifreeze/Coo lant (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 perfo rm
such maintenance in order to maintain the emission warranty or manufacturer recall liability. Other maintenance items and inter vals are
required.

Fluids and LubricantsINFOID:0000000006220904
*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 autom atic
transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle limited wa rranty.
*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 t han 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 °C (32 °F)
*7: See an INFINITI dealer for service for synthetic oil.
*8: Using Hydraulic Suspen sion fluid other than Genuine NISSAN Hydraulic Susp ension fluid will damage the Hydraulic Suspension,
which is not covered by the INFINITI new vehicle limited warranty. See an INFINITI retailer for recommended hydraulic suspensio n fluid.
*9: The fluid capacity is the reference value.
Engine Oil RecommendationINFOID:0000000006287732
NISSAN recommends the use of an energy conservi ng 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) ce rtification and SAE viscosity standard. These oils
have the API certification mark on t he front of the container. Oils which do not have the specified quality label
should not be used as they could cause engine damage.

FUEL LINES : InspectionINFOID:0000000006394850
 Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leakage, cracks, damage, loose connections, chafing or
deterioration.
 If necessary, repair or replace damaged parts.
AIR CLEANER FILTER
AIR CLEANER FILTER : Removal and InstallationINFOID:0000000006394838
REMOVAL
NOTE:
 The viscous paper type filter does not need cleaning between replacement intervals.
 Replace the air filter as necessary for periodic maintenance. Refer to MA-6, "
Introduction of Periodic Mainte-
nance".
1. Unhook clips, and lift air cleaner case (upper).
2. Remove air cleaner filter from air cleaner case.
INSTALLATION
Install is the reverse order of removal.
ENGINE OIL
ENGINE OIL : DrainingINFOID:0000000006394841
WARNING:
 Be careful not to burn yourself, as th e engine and engine oil may be hot.
 Prolonged and repeated contact with used engine oil may cau se skin cancer; try to avoid direct skin
contact with used oil. If skin contact is made, w ash thoroughly with soap or hand cleaner as soon as
possible.
1. Warm up the engine, and check for any oil leaks.
2. Stop the engine and wait for at least 10 minutes.
3. Remove drain plug and oil filler cap to drain the old oil.
ENGINE OIL : RefillingINFOID:0000000006394842
1. Install drain plug with new washer. CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil. Engine oil specificat ion and viscosity:
Refer to MA-10, "
Fluids and Lubricants".
CAUTION:
 The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
 Always use oil level gauge to determine the proper amount of engine oil in engine.
