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 owners can perform the
checks and inspections themselves or they can have their NISSAN dealers dothem for a nominal charge.
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise specified.
Item Reference page
TiresCheck the pressure with a gauge periodically when at a service station,
including the spare, and adjust to the specified pressure if necessary. Check
carefully for damage, cuts or excessive wear.—
Windshield wiper
bladesCheck for cracks or wear if not functioning correctly. —
Doors and engine
hoodCheck that all doors, the engine hood, the trunk lid and back door operate
properly. Also ensure 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 for
lubrication frequently.BT-7
BT-16
Tire rotationTires should be rotated every 10,000 km (6,000 miles). SU-7
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
LampsMake sure that the headlamps, stop lamps, tail lamps, turn signal lamps,
and other lamps are all operating properly and installed securely. Also check
headlamp aim.—
Warning lamps and
chimesMake sure that all warning lamps and buzzers/chimes are operating prop-
erly.—
Steering wheelCheck that it has the specified play.
Check for changes in the steering conditions, such as excessive free play,
hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)—
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 belt webbing for cuts, fraying, wear or damage.RS-4
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.
Item Reference page
Windshield washer
fluidCheck that there is adequate fluid in the tank. —
Engine coolant levelCheck the coolant level when the engine is cold. LC-18, LC-43
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off
the engine.LC-8, LC-30
Brake and clutch
fluid levelsMake sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.BR-7
BatteryCheck the fluid level in each cell. It should be between the “MAX” and “MIN”
lines.—

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-34, "
FUEL PRESSURE RELEASE" (WITH EURO-OBD), EC-427,
"FUEL PRESSURE RELEASE" (WITHOUT EURO-OBD).
3. Remove ignition coil and spark plug from each cylinder.
Refer to IGNITION COIL EM-24, "
Removal and Installation" and SPARK PLUG EM-25, "Removal and
Installation" .
4. Connect engine tachometer (not required in use of CONSULT-II).
5. Disconnect fuel injector harness connector so that no fuel is injected.
6. Install compression tester with adapter onto spark plug hole.
●Use compression gauge whose picking up end inserted to spark
plug hole is smaller than 20 mm (0.79 in) in diameter. Otherwise,
it may be caught by cylinder head during removal.
7. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.
Compression pressure
[kPa (bar, kg/cm2 , psi)/rpm]
CAUTION:
Always use a fully changed battery to obtain specified engine speed.
●If the engine speed is out of specified range, check battery liquid for proper gravity. Check engine speed
again with normal battery gravity.
●If compression pressure is below minimum value, check valve clearances and parts associated with com-
bustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head gas-
ket). After the checking, measure compression pressure again.
●If some cylinders have low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, the piston rings may be worn out or damaged. Check
the piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, the valves may be mal-
functioning. Check the valves for damage. Replace the valve or valve seat accordingly.
●If two adjacent cylinders have respectively low compression pressure and their compression remains low
even after the addition of engine oil, the gaskets are leaking. In such a case, replace the cylinder head
gaskets.

Changing Engine OilNJLC0035WARNING:
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 oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.

PFP:23796
Component DescriptionEBS00K9G
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.
