WARNING:
 Be careful not to get burn yourself, as engine oil may be hot.
 Prolonged and repeated contact with used engine
oil may cause skin cancer. Try to avoid direct skin
contact with used engine oil. If skin contact is made, wash thorough ly with soap or hand cleaner as
soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-5, "
Inspec-
tion".
3. Stop the engine and wait for 10 minutes.
4. Loosen oil filler cap and then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. Refer to EM-30, "
Component (2WD Models)".
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Engine oil specificat ion and viscosity:
Refer to MA-9, "
Fluids and Lubricants".
Engine oil capacity (Approximate):
Unit: (US qt, lmp qt)
CAUTION:
 When filling engine oil, do not pull out oil level gauge.
 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.
8. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
9. Stop the engine and wait for 10 minutes.
10. Check the engine oil level. Refer to LU-5, "
Inspection".

WARNING:
Be careful not to get burn yourself, as en
gine oil and engine coolant may be hot.
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator and cylinder block. Refer to CO-10, "
Changing Engine Coolant" and

ENGINE OIL LEVEL
NOTE:
Before starting engine, put vehicle horizontally and check
the engine oil level. If engine is already started, stop
it and allow 15 minutes before checking.
1. Pull out oil level gauge and wipe it clean.
2. Insert oil level gauge and make sure the engine oil level is within the range shown in the figure.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE
 Check engine oil for white turbidity or heavy contamination.
 If engine oil becomes turbid and white, it is highl y probable that it is contaminated with engine coolant.
Repair or replace damaged parts.
ENGINE OIL LEAKAGE
Check for oil leakage around the following area.
Oil pan
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Oil cooler
 Intake valve timing control cover
 Intake valve timing control solenoid valve
 Front cover
 Chain tensioner cover
 Mating surface between cylinder block and cylinder head
 Mating surface between cylinder head and rocker cover

OIL PRESSURE CHECK
WARNING:
 Be careful not to burn yoursel f, as engine oil may be hot.
 Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to "ENGINE OIL LEVEL".
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure switch, and remove oil pressure switch using deep socket (commercial ser-

4. Install oil pressure gauge and hose (SST).
5. Start engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Eng ine oil temperature at 80°C (176 °F)]
Uni t: kPa (kg/cm2, psi)
If difference is extreme, check oil passage and oil pump for oil leaks.
7. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil presser switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-44, "
Recommended Chemical Prod-
uct and Sealant".
c. After warming up engine, make sure there is no leakage of engine oil with running engine.

GENERAL MAINTENANCE
Explanation of Gene ral MaintenanceINFOID:0000000001328893
General maintenance includes those items which shoul d be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owners can perform
checks and inspections themselves or have their INFINITI dealers do them.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
INSIDE THE VEHICLE The maintenance items listed here should be checked on a regular basis, such as when performing periodic maintenance, cleaning the vehicle,
etc.
Item Reference page
Tires Check the pressure with a gauge, including the spare, at least once a month
and always prior to a long distance trips. Adjust to the specified pressure if nec-
essary. Check carefully for damage, cuts or excessive wear. —
Wheel nuts When checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary. —
Windshield Clean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary. —
Tire rotation Tires should be rotated every 12,000 km (7,500 miles). MA-31
Transmitter compo-
nents in tire pressure
monitoring system
(TPMS)Replace grommet seal, valve core and cap of the transmitter in TPMS every tire
replacement by reaching wear limit of tire.
WT-10
Wheel alignment and
balanceIf the vehicle pulls to either side while driving on a straight and level road, or if
you detect uneven or abnormal tire wear, there may be a need for wheel align-
ment. If the steering wheel or seat vibrates at normal highway speeds, wheel
balancing may be needed. MA-30
,
FSU-5
Windshield wiper
blades Check for cracks or wear if they do not wipe properly. —
Doors and engine
hood Check that all doors and the engine hood operate smoothly as well as the trunk
lid and back hatch. Also make sure that all latches lock securely. Lubricate if
necessary. Make sure that the secondary latch keeps the hood from opening
when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check lubri-
cation frequently. MA-35
Lamps
Make sure that the headlamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head-
lamp aim. Clean the headlamps on a regular basis. —
Item
Reference page
Warning lamps and
chimes Make sure that all warning lamps and chimes are operating properly. —
Windshield wiper and
washer Check that the wipers and washer operate properly and that the wipers do not
streak.
—
Windshield defroster Check that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner. —
Steering wheel Check that it has the specified play. Be sure to check for changes in the steering
condition, such as excessive play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in) —
Seats Check seat position controls such as seat adjusters, seatback recliner, etc. to
make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restrains move up and down smoothly and that the
locks (if equipped) hold securely in all latched positions. Check that the latches
lock securely for folding-down rear seatbacks. —
Seat belts Check that all parts of the seat belt system (e.g. buckles, anchors, adjusters
and retractors) operate properly and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying, wear or damage. MA-35

ENGINE MAINTENANCE (VQ35DE ENGINE)
Checking Drive BeltsINFOID:0000000001328900
WARNING:
Be sure to perform when engine is stopped.
1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on belt midway
between pulleys.
 Inspection should be done only when engine is cold, or over 30 minutes after engine is stopped.
 Measure the belt tension with belt tension gauge (Commercial service tool: BT3373-F or equivalent) (A) at points marked
shown in the figure.
 When measuring the deflection, apply 98 N (10 kg, 22 lb) at
the marked point.
 Adjust if the belt deflection exceeds the limit or if the belt ten- sion is not within specifications.
CAUTION:
• When checking the belt deflect ion or the tension immedi-
ately after installation, first ad just it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust
to the specified value to avo id variation in deflection
between pulleys.
 Tighten idler pulley lock nut by hand and measure the deflection or the tension without loose-
ness.
Belt Deflection and Tension
*: If belt tension gauge cannot be installed at check points shown, check drive belt tension at different location on belt.
