Explanation of General MaintenanceNLS00004
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.ItemReference page
TiresCheck 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 nutsWhen checking the tires, make sure no nuts are missing, and check for any
loose nuts. Tighten if necessary.—
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 cannot be rotated in this vehicle, as front tires are different size from rear
tires and the direction of wheel rotation is fixed in each tire.MA-25
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-23
, FSU-6
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 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-28
LampsMake 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. —
ItemReference page
Warning lamps and
chimesMake sure that all warning lamps and chimes are operating properly. —
Windshield wiper and
washerCheck that the wipers and washer operate properly and that the wipers do not
streak.—
Windshield defrosterCheck that the air comes out of the defroster outlets properly and in sufficient
quantity when operating the heater or air conditioner.—
Steering wheelCheck 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)—
SeatsCheck 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.—

2. Open radiator drain plug at the bottom of radiator, and then
remove radiator cap.
When drain all of engine coolant in the system, open water drain plugs on engine cylinder block.
Refer to EM-108, "
DISASSEMBLY" .
3. Remove reservoir tank as necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration.
If contaminated, flush the engine cooling system. Refer to MA-15, "
FLUSHING COOLING SYSTEM" .
REFILLING ENGINE COOLANT
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-111,
"ASSEMBLY" .
2. Make sure that each hose clamp has been firmly tightened.
3. Remove air relief plug (1) on heater hose (2).
4. Fill radiator and reservoir tank to specified level.

Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2-1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.

Use Genuine NISSAN Long Life Antifreeze/Coolant or
equivalent mixed with water (distilled or demineralized).
Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRI-
CANTS".

When engine coolant overflows air relief hole on heater hose,
install air relief plug with new O-ring.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000
rpm.

Make sure thermostat condition by touching radiator hose (lower) to see flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop engine and cool down to less than approximately 50°C (122°F).

Cool down using fan to reduce the time.

If necessary, refill radiator up to filler neck with engine coolant.
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer
drops.
10. Check cooling system for leaks with engine running.
11. Warm up engine, and check for sound of engine coolant flow while running engine from idle up to 3,000
rpm with heater temperature controller set at several position between “COOL” and “WARM”.

Sound may be noticeable at heater unit.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 4 through 7 until engine coolant level no
longer drops.

Clean excess engine coolant from engine.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-111,
"ASSEMBLY" .
2. Remove air relief plug (1) on heater hose (2).
3. Fill radiator with water until water spills from the air relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.Reservoir tank capacity (at “MAX” level)
