GENERAL MAINTENANCEPFP:00000
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
(YD25DDTi)
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off the
engine.MA-25
(YD25DDTi)
Brake and clutch fluid
levelsMake sure that the brake and clutch fluid levels are between the “MAX” and
“MIN” lines on the reservoir.MA-28

INSTALLATION
1. Clean piping connection points, and insert male-side piping into female-side piping.
2. Push inserted male-side piping harder so that female-side piping flare stretches garter spring.
3. If inside diameter of garter spring becomes larger than outside diameter of female-side piping flare, garter
spring seats on flare. Then, it fits in between male-side piping cage and female-side piping flare to anchor
piping connection point.
NOTICE:
When garter spring seats on flare, and fits in between male-side piping cage and female-side piping flare,
it clicks.
CAUTION:
lFemale-side piping connection point is thin. So, when inserting male-side piping, take care not
to deform female-side piping. Slowly insert it in axial direction.
lInsert piping securely until a click is heard.
lAfter piping connection is completed, pull male-side piping by hand to make sure connection
does not come loose.
NOTE:
One-touch joint connection is used in points below.
lLow-pressure flexible hose to evaporator (O-ring size: 16)
lHigh-pressure flexible hose to condenser (O-ring size: 12)
lHigh-pressure pipe 1 to high-pressure pipe 2 (O-ring size: 8)
lHigh-pressure pipe 1 to condenser (O-ring size: 8)
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
lThe O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of
the O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing
characteristics.
