General MaintenanceELS001HT
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.
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.
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
TiresCheck the pressure with a gauge periodically when at a service station, includ-
ing 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 prop-
erly. 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.MA-39
,BL-12
Tire rotationTires should be rotated every 10,000 km (6,000 miles) for 2WD models and
every 5,000 km (3,000 miles) for 4WD models.MA-34
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 properly. —
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.MA-40
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.MA-19

Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EGS001M0
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN/INFINITI dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harnesses or
harness connectors.
Precautions for Steering SystemEGS001L9
lIn case of removing steering gear assembly, make the final tightening with grounded and unloaded vehi-
cle condition, and then check wheel alignment.
lObserve the following precautions when disassembling.
–Before disassembly, thoroughly clean the outside of the unit.
–Disassembly should be done in a clean work area. It is important to prevent the internal parts from becom-
ing contaminated by dirt or other foreign matter.
–For easier and proper assembly, place disassembled parts in order on a parts rack.
–Use nylon cloth or paper towels to clean the parts; common shop rags can leave lint that might interfere
with their operation.
–Do not reuse non-reusable parts.
–Before assembling, apply the specified grease to the directed parts.

Checking Fluid LevelEGS001LD
lCheck fluid level with engine stopped.
lMake sure that fluid level is between MIN and MAX.
lFluid levels at HOT and COLD are different. Do not confuse
them.
CAUTION:
lThe fluid level should not exceed the MAX line. Excessive
fluid will cause fluid leakage from the cap.
lDo not reuse drained power steering fluid.
lRecommended fluid is Type DEXRONTMIII or equivalent.
Checking Fluid LeakageEGS001LE
Check hydraulic connections for fluid leakage, cracks, damage,
looseness, or wear.
1. Run engine until the fluid temperature reaches 50 to 80°C(122
to 176°F) in reservoir tank, and keep engine speed idle.
2. Turn steering wheel several times from full left stop to full right
stop.
3. Hold steering wheel at each lock position for five seconds and
carefully, check for fluid leakage.
CAUTION:
Do not hold the steering wheel in a locked position for more
than 10 seconds. (There is the possibility that oil pump may
be damaged.)
4. If fluid leakage at connections is noticed, then loosen flare nut and then retighten. Do not over-tighten con-
nector as this can damage O-ring, washer and connector.
5. If fluid leakage from oil pump is noticed, check oil pump. Refer toPS-25, "
POWER STEERING OIL
PUMP".
6. Check steering gear boots for accumulation of fluid, indicating from steering gear.
Air Bleeding Hydraulic SystemEGS001LF
If air bleeding is not complete, the following symptoms can be observed.
lBubbles are created in reservoir tank.
lClicking noise can be heard from oil pump.
lExcessive buzzing in the oil pump
NOTE:
Fluid noise may occur in the steering gear or oil pump. This does not affect performance or durability of
the system.
1. Turn steering wheel several times from full left to full right stop with engine off.
CAUTION:
Turn steering wheel while filling reservoir tank with fluid so as not to lower fluid level below the
MIN line.
2. Start engine and hold steering wheel at each lock position for 3 seconds at idle to check for fluid leakage.
3. Repeat step 2 above several times at approximately 3 second intervals.
CAUTION:
Do not hold the steering wheel in a locked position for more than 10 seconds. (There is the possi-
bility that oil pump may be damaged.)
4. Check fluid for bubbles and while contamination.HOT : Fluid temperature 50 - 80°C (122 - 176°F)
COLD : Fluid temperature 0 - 30°C(32-86°F)
