ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power

EXTERIOR LAMP BATTERY SAVER CONTROL
When the combination switch (lighting switch) is in the 1ST or 2ND position (or if auto light system is acti-
vated), and the ignition switch is turned from ON or ACC to OFF, the battery saver control function is activated.
Under this condition, the illumination lamps remain illuminated for 5 minutes, then the illumination lamps are
turned off.
When the lighting switch is turned from OFF to 1ST or 2ND position (or if auto light system is activated) after
illumination lamps are turned off by the battery saver control, the illumination lamps illuminate again.
Exterior lamp battery saver control mode can be changed by the function setting of CONSULT-II.

InspectionINFOID:0000000003531555
OIL LEVEL
• Before starting the engine make sure the vehicle is parked on a flat
and level surface, then check the oil level. If the engine is already
running, turn it off and allow 10 minutes before checking.
• Check that the oil level is within the low (L) and high (H) range as
indicated on the dipstick.
• If the engine oil level is out of range, add oil as necessary. Refer to
GI-45, "
Recommended Chemical Product and Sealant".
OIL APPEARANCE
• Check the engine oil for a white milky appearance or excessive contamination.
• If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair the broken
parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•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
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
CAUTION:
• Be careful not to burn yourself, as engine oil may be hot.
• Put the selector lever in the Park “P” position.
1. Check the engine oil level. Refer to LU-8, "
Inspection".
2. Remove engine front undercover using power tool.
3. Disconnect the oil pressure switch harness connector.
4. Remove the oil pressure switch (A).

, psi)
CAUTION:
If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
8. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-45, "
Recommended Chemical Prod-
uct and Sealant".
c. After warming up engine, make sure there is no leakage of engine oil with engine running.

CAUTION:
• Be careful not to burn yourself, as the engine oil is 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.
1. Remove engine front undercover using power tool.
2. Warm up engine, and check for oil leakage from engine compo-
nents. Refer to LU-8, "
Inspection".
3. Stop engine and wait for 10 minutes.
4. Loosen oil filler cap, then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer.
CAUTION:
• Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Refer to MA-10, "
Fluids and Lubricants".

GENERAL MAINTENANCE
GENERAL MAINTENANCE
General MaintenanceINFOID:0000000003533859
General maintenance includes those items which should be checked during the normal day-to-day operation
of the vehicle. They are essential if the vehicle is to continue operating properly. The owner can perform these
checks and inspections or have their INFINITI dealers perform 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.
ItemReference page
TiresCheck the pressure with a gauge at least once a month and always prior to a
long distance trip. Adjust to the specified pressure if necessary. Check carefully
for damage, cuts or excessive wear.—
Wheel lug nutsWhen checking the tires, make sure no nuts are missing, and check for any loose
nuts. Tighten if necessary.WT-7, "
Rotation"
WindshieldClean the windshield on a regular basis. Check the windshield at least every six
months for cracks or other damage. Repair as necessary.—
Tire rotationTires should be rotated every 12,000 km (7,500 miles).WT-7, "
Rotation"
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 bal-
ancing may be needed.WT-6, "Balancing
Wheels", FSU-6, "Front
Wheel Alignment"
Windshield wiper
bladesCheck for cracks or wear if they do not wipe properly.
—
Doors and engine
hoodCheck that all doors and the engine hood operate smoothly as well as the 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-30, "
Lubricating
Locks, Hinges and Hood
Latches"
Lamps
Make sure that the head lamps, stop lamps, tail lamps, turn signal lamps, and
other lamps are all operating properly and installed securely. Also check head
lamp aim. Clean the head lamps on a regular basis.LT- 2 0 , "Aiming Adjust-
ment" for US, LT- 3 3 ,

make sure they operate smoothly and that all latches lock securely in every po-
sition. Check that the head restraints 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 seat backs.—
Seat beltsCheck 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

3. Open the radiator drain plug at the bottom of the radiator, and
remove the radiator filler cap. This is the only step required
when partially draining the cooling system (radiator only).
CAUTION:
Do not to allow the coolant to contact the drive belts.
4. When draining all of the coolant in the system for engine
removal or repair, it is necessary to drain the cylinder block.
Remove the RH cylinder block drain plug to drain the right bank
and the oil cooler hose to drain the left bank as shown.
5. Remove the reservoir tank to drain the engine coolant, then clean the reservoir tank before installing it.
6. Check the drained coolant for contaminants such as rust, corrosion or discoloration.
If the coolant is contaminated, flush the engine cooling system. Refer to CO-9, "
Changing Engine Cool-
ant" .
REFILLING ENGINE COOLANT
1. Close the radiator drain plug. Install the reservoir tank, cylinder block drain plug, and the oil cooler hose, if
removed for a total system drain or for engine removal or repair.
• The radiator must be completely empty of coolant and water.
• Apply sealant to the threads of the cylinder block drain plug. Use Genuine High Performance Thread
Sealant or equivalent. Refer to GI-45
.
2. Set the vehicle heater controls to the full HOT and heater ON position. Turn the vehicle ignition ON with
the engine OFF as necessary to activate the heater mode.
3. Remove the vented reservoir cap and replace it with a non-vented reservoir cap before filling the cooling
system.
