NLMA0004
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 do them 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-13
Tire rotationTires should be rotated every 10,000 km (6,000 miles). SU-8
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-3
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-19, LC-59
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off
the engine.LC-8, LC-28
Brake and clutch

Bleeding Hydraulic SystemNLST00141. Raise front end of vehicle until wheels are clear of the ground.
2. Add fluid into oil tank to specified level. Then quickly turn steer-
ing wheel fully to right and left and lightly touch steering stop-
pers.
Repeat steering wheel operation until fluid level no longer
decreases.
3. Start engine.
Repeat step 2. above.
+Incomplete air bleeding will cause the following to occur. When
this happens, bleed air again.
a) Air bubbles in reservoir tank
b) Clicking noise in oil pump
c) Excessive buzzing in oil pump
Fluid noise may occur in the valve or oil pump. This is common
when the vehicle is stationary or while turning the steering wheel
slowly. This does not affect the performance or durability of the
system.

Checking Steering Wheel Turning ForceNLST00151. Park vehicle on a level, dry surface and set parking brake.
2. Start engine.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80°C (140 to 176°F).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360°from the neutral position.
Steering wheel turning force:
26 - 32 N (2.7 - 3.3 kg, 5.8 - 7.2 lb)
5. If steering wheel turning force is out of specification, check
rack sliding force.
a. Disconnect steering column lower joint and knuckle arms from
the gear.
b. Start and run engine at idle to make sure steering fluid has
reached normal operating temperature.
c. Pull tie-rod slowly to move it from neutral position to±11.5 mm
(±0.453 in) at speed of 3.5 mm (0.138 in)/s. Check that rack
sliding force is within specification.
Average rack sliding force:
197 - 255 N (20.1 - 26.0 kg, 44.3 - 57.3 lb)
6. If rack sliding force is not within specification, replace steering
gear assembly.
7. If rack sliding force is OK, inspect steering column. Refer to
ST-13.

Checking Hydraulic SystemNLST0016Before starting, check belt tension, driving pulley and tire pressure.
1. Set Tool. Open shut-off valve. Then bleed air. Refer to“Bleed-
ing Hydraulic System”, ST-8.
2. Run engine at idle speed or 1,000 rpm.
Make sure temperature of fluid in tank rises to 60 to 80°C (140
to 176°F).
WARNING:
Warm up engine with shut-off valve fully opened. If engine is
started with shut-off valve closed, fluid pressure in oil pump
increases to maximum. This will raise oil temperature abnor-
mally.
3. Check pressure with steering wheel fully turned to left and right
positions with engine idling at 1,000 rpm.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 15 seconds.
Oil pump maximum standard pressure:
SR engine
8,600 - 9,200 kPa (86.0 - 92.0 bar, 87.7 - 93.8
kg/cm
2, 1,247 - 1,334 psi)
QG engine
8,600 - 9,200 kPa (86.0 - 92.0 bar, 87.7 - 93.8

2, 1,247 - 1,334 psi)
YD engine
8,800 - 9,400 kPa (88.0 - 94.0 bar, 88.7 - 95.8
kg/cm
2, 1,261 - 1,362 psi)
+If pressure reaches maximum operating pressure, system is
OK.
+If pressure increases above maximum operating pressure,
check power steering pump flow control valve. Refer to ST-21.
4. If power steering pressure is below the maximum operating
pressure, slowly close shut-off valve and check pressure
again.
CAUTION:
Do not close shut-off valve for more than 15 seconds.
+If pressure increases to maximum operating pressure, gear is
damaged. Refer to“Removal and Installation”, ST-16.
+If pressure remains below maximum operating pressure, pump
is damaged. Refer to“Disassembly”, ST-24.
5. After checking hydraulic system, remove Tool and add fluid as
necessary. Then completely bleed air out of system. Refer to
ST-8.
