OIL PRESSURE CHECK
WAR NING :
Be careful not to get burn yourself, as engine oil may be hot.
Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
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-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
Remove the oil pressure switch using a 26 mm (1.02 in) box
wrench. (AWD models)
4. Install the oil pressure gauge (SST) and hose (SST).
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load.
NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80
C (176 F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure switch as follows:

WAR NING :
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 thoroughly with soap or hand
cleaner as soon as possible.

ENGINE
OIL LEAKAGE" .
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove mounting bolts, and then pull down the rear of front
engine undercover (1) and secure it using clip.
5. Remove drain plug (2) and then drain engine oil.
6. Install drain plug with new washer. Refer to EM-29, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil.
Engine oil specification and viscosity:
Refer to MA-12, "
RECOMMENDED 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 oil 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-7, "

GENERAL MAINTENANCE
Revision: 2006 January2006 M35/M45
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically (e.g. each time you check the engine oil or refuel). Parking brakeCheck that the pedal has the proper travel and make sure that the vehicle is
held securely on a fairly steep hill when only the parking brake is applied.PB-2
Automatic transmis-
sion "Park" mecha-
nismCheck that the lock release button on the selector lever operates properly and
smoothly. On a fairly steep hill check that the vehicle is held securely with the
selector lever in the P (Park) position without applying any brakes.— ItemReference page
ItemReference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold.MA-15
, MA-22
Radiator and hosesCheck the front of the radiator and clean off any dirt, insects, leaves, etc., that
may have accumulated. Make sure the hoses have no cracks, deformation,
deterioration or loose connections.—
Brake fluid levelMake sure that the brake fluid level is between the “MAX” and “MIN” lines on
the reservoir.MA-35

BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines. Vehicles operated in high temperatures or under severe conditions
require frequent checks of the battery fluid level.SC-5, "

ELECTROLYTE LEVEL"
Engine drive beltsMake sure that no belt is frayed, worn, cracked or oily.MA-14, MA-22
Engine oil levelCheck the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine.MA-18, MA-25
Power steering fluid
level and linesCheck the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.MA-37
Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately
locate the trouble and correct it.MA-29
UnderbodyThe underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these sub-
stances, otherwise rust will form on the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean those areas where mud and dirt
can easily accumulate.—
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the vehicle
has been parked for a while. Water dripping from the air conditioner after use is
normal. If you should notice any leaks or gasoline fumes are evident, check for
the cause and correct it immediately.—

RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and Lubricants NLS0007E
*1: For further details, see “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 INFINITI new
vehicle limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0
C (32F).
*4: DEXRONTM III/ MERCONTM or equivalent may also be used. Outside the continental United States and Alaska contact an INFINITI

SAE 5W-30 viscosity oil is preferred for all temperatures. SAE
10W-30 and 10W-40 viscosity oil may be used if the ambient
temperature is above -18
C (0F)
Anti-Freeze Coolant Mixture RatioNLS0007G
The engine cooling system is filled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only Genuine
NISSAN Long Life Antifreeze/ Coolant or equivalent with the
proper mixture ratio of 50% anti-freeze and 50% demineralized
water/distilled water.
Other types of coolant solutions may damage your cooling sys-
tem.
