OIL PRESSURE CHECK
WARNING:
●
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
2.
Remove splash guard (RH).
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.
4.
Install 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:
a.
Remove old liquid gasket adhering to oil pressure switch and mating surface.
b.
Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or equivalent. Refer to
.

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.
7.
Warm up engine and check area around drain plug and oil filter for engine oil leakage.
8.
Stop engine and wait for 10 minutes.

GENERAL MAINTENANCE
Revision: 2005 August
2005 Murano
GENERAL MAINTENANCE
PFP:00000
Explanation of General Maintenance
ALS000D7
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
checks and inspections themselves or have their NISSAN 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).
Wheel alignment and
balance
If 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.
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.
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
position. 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.
Accelerator pedal
Check the pedal for smooth operation and make sure the pedal does not catch
or require uneven effort. Keep the floor mats away from the pedal.
—
Brakes
Check that the brake does not pull the vehicle to one side when applied.

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).
Brake pedal and
booster
Check the pedal for smooth operation and make sure it has the proper distance
under it when depressed fully. Check the brake booster function. Be sure to
keep the floor mats away from the pedal.
Parking brake
Check 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.
CVT P (Park) position
mechanism
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.

Item

Item
Reference page
Windshield washer
fluid
Check that there is adequate fluid in the tank.
—
Engine coolant level
Check the coolant level when the engine is cold.
Radiator and hoses
Check 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 level
Make sure that the brake fluid level is between the “MAX” and “MIN” lines on the
reservoir.
Battery
Check 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.
—
Engine drive belts
Make sure that no belt is frayed, worn, cracked or oily.
Engine oil level
Check the level on the oil level gauge after parking the vehicle on a level spot
and turning off the engine.
Power steering fluid
level and lines
Check the level on the dipstick with the engine off. Check the lines for improper
attachment, leaks, cracks, etc.
Exhaust system
Make 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.
Underbody
The 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 leaks
Check 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.

PERIODIC MAINTENANCE
PFP:00026
Introduction of Periodic Maintenance
ALS000D8
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage/time intervals.
Schedule 1
Follow Periodic Maintenance Schedule 1 if the driving habits frequently include
one or more of the following driving conditions:
●
Repeated short trips of less than 5 miles (8 km).
●
Repeated short trips of less than 10 miles (16 km) with outside temperatures
remaining below freezing.
●
Operating in hot weather in stop-and-go “rush hour” traffic.
●
Extensive idling and/or low speed driving for long distances, such as police,
taxi or door-to-door delivery use.
●
Driving in dusty conditions.
●
Driving on rough, muddy, or salt spread roads.
●
Towing a trailer, using a camper or a car-top carrier.
