PRE-DELIVERY INSPECTION ITEMS
MA-2

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.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be performed from time to time, unless otherwise
speci®ed.
TiresCheck the pressure with a gauge periodically when at a service station, including the
spare, and adjust to the speci®ed pressure if necessary. Check carefully for damage, cuts or
excessive wear.Ð
Windshield wiper bladesCheck for cracks or wear if they do not wipe properly. Ð
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 hinges, latches, rollers and
links 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 fre-
quently.MA-27
Tire rotationTires should be rotated every 5,000 km (3,000 miles) for 4WD models. MA-25
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle, etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating properly and installed securely. Also check headlight aim.Ð
Warning lights and chimesMake sure that all warning lights and chimes are operating prop-
erly.Ð
Steering wheelCheck for change in the steering conditions, such as excessive free play, hard
steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
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-27
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.
Windshield washer ¯uidCheck that there is adequate ¯uid in the tank. Ð
Engine coolant levelCheck the coolant level when the engine is cold. MA-14, 15
Engine oil levelCheck the level after parking the vehicle on a level spot and turning off the
engine.MA-13, 14
Brake and clutch ¯uid levelMake sure that the brake and clutch ¯uid levels are between the
``MAX'' and ``MIN'' lines on the reservoir.MA-20, 23
BatteryCheck the ¯uid level in each cell. It should be between the ``MAX'' and ``MIN'' lines. Ð

MA-3

The following tables show the normal maintenance schedule. Depending upon weather and atmospheric
conditions, varying road surfaces, individual driving habits and vehicle usage, additional or more frequent
maintenance may be required.
Periodic maintenance beyond the last period shown on the tables requires similar maintenance.

RECOMMENDED FLUIDS AND LUBRICANTS
MA-9

Anti-freeze Coolant Mixture Ratio
The engine cooling system is ®lled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only an eth-
ylene glycol anti-freeze with the proper mixture ratio. See the
following examples:

The use of other types of coolant solutions may damage your
cooling system.

Changing Engine Oil
WARNING:
+Be careful not to burn yourself, as engine oil is hot.
+Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Remove oil ®ller cap and drain plug.
3. Drain oil and ®ll with new engine oil.
