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, 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) Periodic maintenance is not required. However, if valve noise increases, inspect valve clearance.
* Maintenance items and inte rvals with “*” are recommended by NISSAN for reliable vehicle operation. The owner need not perform

PERIODIC MAINTENANCE
(1) If towing a trailer, or using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every 30,000 miles
(48,000 km) or 24 months. Using automatic transmission fluid other than Genui ne NISSAN Matic S ATF or Matic J 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.
(2) Refer to “Tire rotation” unde r the “General maintenance” heading earlier in this section.

• When removing, prepare a shop cloth to ab
sorb any engine oil leakage or spillage.
• Do not allow engine oil to adhere to the drive belts.
• Completely wipe off any engine oil that adheres to the engine and the vehicle.
INSTALLATION
1. Remove foreign materials adhering to the oil filter installation surface.
2. Apply engine oil to the oil seal circumference of the new oil filter.
3. Screw the oil filter manually until it touches the installation sur-
face, then tighten it by 2/3 turn. Or tighten to specification.
4. Refill the engine with new engine oil. Refer to LU-9, "
Changing
Engine Oil".
5. Inspect the engine for oil leakage. Follow the "INSPECTION AFTER INSTALLATION" procedure.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level. Refer to LU-8, "Inspection".
2. Start the engine and check for engine oil leakage.
3. Stop the engine and wait for 10 minutes.

8. Insert the tip of an air gun into the end of the cooler outlet hose.
9. Wrap a shop rag around the air gun tip and end of cooler outlet hose.
10. Blow compressed air regulated to 490 - 883 kPa (5 - 9 kg/cm
2,
71 - 128 psi) through the cooler outlet hose to force any remain-
ing A/T fluid into the coffee filter.
11. Remove the coffee filter from the end of the cooler inlet hose.
12. Perform A/T fluid cooler inspection. Refer to TM-183, "A/T Fluid
Cooler Cleaning".
A/T FLUID COOLER INSPECTION PROCEDURE
1. Inspect the coffee filter for debris.
a. If small metal debris less than 1mm (0.040 in) in size or metal
powder is found in the coffee filter, this is normal. If normal
debris is found, the A/T fluid cooler/radiator can be re-used and
the procedure is ended.
b. If one or more pieces of debris are found that are over 1mm (0.040 in) in size and/or peeled clutch facing material is found in
the coffee filter, the fluid cooler is not serviceable. The A/T fluid
cooler/radiator must be replac ed and the inspection procedure is
ended. Refer to CO-15, "Removal and Installation"
.
A/T FLUID COOLER FINAL INSPECTION
After performing all procedures, ensure that all remaining oil is cleaned from all components.

5. Start the engine, then measure the line pressure at both idle and the stall speed.
CAUTION:
 Keep the brake pedal pressed all the way down during
measurement.
 When measuring the line pressu re at the stall speed, refer
to TM-186, "Inspection and Judgment"
.
6. After the measurements are complete, install the oil pressure detection plug and tighten to the regulation torque below.

Judgement Possible cause
Idle speed Low for all positions
(P, R, N, D)
Possible causes include malfunctions in the pressure supply system and low oil pump output.
For example
 Oil pump wear
 Pressure regulator valve or plug sticking or spring fatigue
 Oil strainer
⇒ oil pump ⇒ pressure regulator valve passage oil leak
 Engine idle speed too low
Only low for a spe-
cific position Possible causes include an oil pressure leak in a passage or device related to the position after
the pressure is distributed by the manual valve.
High Possible causes include a sensor malfunction or malfunction in the line pressure adjustment func-
tion.
For example
 Accelerator pedal position signal malfunction
 ATF temperature sensor malfunction
 Line pressure solenoid malfunction (sticking in “OFF” state, filter clog, cut line)
 Pressure regulator valve or plug sticking
Stall speed Oil pressure does
not rise higher than
the oil pressure for
idle.
Possible causes include a sensor malfunction or malfunction in the pressure adjustment function.
For example
 Accelerator pedal position signal malfunction
 TCM breakdown
 Line pressure solenoid malfunction (shorting, sticking in“ ON” state)
 Pressure regulator valve or plug sticking
 Pilot valve sticking or pilot filter clogged
The pressure rises,
but does not enter
the standard posi-
tion. Possible causes include malfunctions in the pressure supply system and malfunction in the pres-
sure adjustment function.
For example
 Accelerator pedal position signal malfunction
 Line pressure solenoid malfunction (sticking, filter clog)
 Pressure regulator valve or plug sticking
 Pilot valve sticking or pilot filter clogged
Only low for a spe-
cific position Possible causes include an oil pressure leak in a passage or device related to the position after
