Trouble Diagnoses
EKS003CF
Aiming Adjustment EKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.
●Keep all tires inflated to correct pressures.
●Place vehicle and tester on one and same flat surface.
●See that there is no-load in vehicle (coolant, engine oil filled up to correct level and full fuel tank) other
than the driver (or equivalent weight placed in driver's position).

WARNING LAMPS
Electrical Components Inspection
EKS002HK
FUEL WARNING LAMP OPERATION CHECK
1. Turn ignition switch “OFF”.
2. Disconnect sub fuel level sensor unit harness connector B125
(LHD models) or B21 (RHD models).
3. Connect a resistor (80Ω) between sub fuel level sensor unit har-
ness connector terminal 1(G) and ground.
4. Turn ignition switch “ON”.
The fuel warning lamp should come on.
OIL PRESSURE SWITCH CHECK
Check the continuity between the terminals of oil pressure switch
and body ground.
DIODE CHECK
●Check continuity using an ohmmeter.
●Diode is functioning properly if test results are as shown in the
figure at left.
●Check diodes at the combination meter harness connector
instead of on the combination meter assembly. Refer toDI-44,
"Wiring Diagram — WARN —/ LHD Models" orDI-50, "Wiring
Diagram — WARN — / RHD Models" .
NOTE:
Specification may vary depending on the type of tester. Before
performing this inspection, be sure to refer to the instruction
manual for the tester to be used.

GENERAL MAINTENANCE
GENERAL MAINTENANCE
PFP:00000
General MaintenanceELS000AL
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.BL-4
,BL-8
Tire rotationTires should be rotated every 5,000 km (3,000 miles).MA-38
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 head-
lamp 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, a dju sters and
retractors) operate properly and smoothly, and are installed securely. Check the
belt webbing for cuts, fraying, wear or damage.SB-3
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.CO-29

Checking Differential Gear Oil
ELS000BF
1. Check for oil leakage and oil level.
CAUTION:
Gaskets are not reusable. Never reuse them.
Changing Differential Gear OilELS000BG
1. Drain oil from drain plug and refill with new gear oil.
2. Check oil level.
CAUTION:
Gaskets are not reusable. Never reuse them.
Balancing WheelsELS000BH
Adjust wheel balance using the road wheel center.
RotationELS000BI
●After rotating the tires, adjust the tire pressure.
●Retighten the wheel nuts when the vehicle has been driven for
1,000 km (600 miles) (also in cases of a flat tire, etc.).
CAUTION:
When installing wheels, tighten them diagonally by dividing
the work two to three times in order to prevent the wheels
from developing any distortion.Filler plug:
