FUEL LINES : InspectionINFOID:0000000006394850
 Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leakage, cracks, damage, loose connections, chafing or

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.

POWER STEERING FLUID
PERIODIC MAINTENANCE
POWER STEERING FLUID
InspectionINFOID:0000000006225597
FLUID LEVEL
1. Check fluid level with engine stopped.
2. Ensure that fluid level is between MIN and MAX.
3. Fluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
 The fluid level should not exceed the MAX line. Excessive flui d causes fluid leakage from the
cap.
 Never reuse drained power steering fluid.
 Always use the specified fluid. Refer to MA-10, "
Fluids and Lubricants".
FLUID LEAKAGE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80 °C (122
to 176 °F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right stop.
3. Hold steering wheel at each lock position for five seconds and carefully, check for fluid leakage.
CAUTION:
Never hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that power steer-
ing oil pump assembly may be damaged.)
4. If fluid leakage at connections is noticed, then loos en flare nut and then retighten. Do not overtighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer to ST-52, "
Inspection".
6. Check steering gear boots for accumulation of fluid indicating from steering gear.
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, the following symptoms can be observed.
 Bubbles are created in reservoir tank.
 Clicking noise can be heard from oil pump.
 Excessive buzzing in the oil pump. NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of the
system.
1. Turn steering wheel several times from full left stop to full right stop with engine off. CAUTION:
Fill reservoir tank with a sufficien t amount of fluid so that fluid level is not below the MIN line while
turning steering wheel.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
HOT : Fluid temperature 50 – 80
°C (122 – 176 °F)
COLD : Fluid temperature 0 – 30 °C (32 – 86 °F)
Recommended fluid : Refer to MA-10, "
Fluids
and Lubricants".
Fluid capacity : Refer to ST-57, "
General
Specifications".

CAUTION:
 Use only Genuine NISSAN Matic S ATF. Never mix with other ATF.
 Using ATF other than Genuine NI
SSAN Matic S ATF will cause deteri oration in driveability and A/T
durability, and may damage the A/T, which is not covered by the INFINITI new vehicle limited war-
ranty.
 When filling ATF, be careful not to scatte r heat generating parts such as exhaust.
1. Step 1
a. Install the O-ring (315268E000) (A) to the charging pipe (310811EA5A) (B).
2. Step 2
a. Use CONSULT-III to check that the ATF temperature is 40 °C (104 °F) or less.
b. Lift up the vehicle.
c. Remove the drain plug from the oil pan, and then drain the ATF.
d. When the ATF starts to drip, temporarily tighten the drain plug to the oil pan. NOTE:
Never replace drain plug and drain plug gasket with new ones yet.
e. Remove overflow plug from oil pan.
f. Install the charging pipe (A) to the overflow plug hole. CAUTION:
Tighten the charging pipe by hand.
g. Install the bucket pump hose (B) to the charging pipe. CAUTION:
Insert the bucket pump hose all the way to the end of the
charging pipe.
h. Fill approximately 3 liters (3-1/8 US qt, 2-5/8 lmp qt) of the ATF.
i. Remove the bucket pump hose to remove the charging pipe, and then temporarily tighten the overflow plug to the oil pan.
CAUTION:
Quickly perform the procedur e to avoid ATF leakage from
the oil pan.
j. Lift down the vehicle.
k. Start the engine and wait for approximately 3 minutes.
l. Stop the engine.
3. Step 3
a. Repeat “Step 2”.
4. Final Step
a. Use CONSULT-III to check that the ATF temperature is 40 °C (104 °F) or less.
b. Lift up the vehicle.
c. Remove the drain plug from the oil pan, and then drain the ATF.

m. Park vehicle on level surface and set parking brake.
n. Shift the selector lever through each gear pos ition. Leave selector lever in “P” position.
o. Lift up the vehicle when the ATF temperature reaches 40 °C (104 °F), and remove the overflow plug from
the oil pan.
