Your new NISSAN has been designed to have
minimum maintenance requirements with long
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your
NISSAN’s fine mechanical condition, as well
as its emission and engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.SCHEDULED MAINTENANCEFor your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “NISSAN Service and
Maintenance Guide”. You must refer to that
guide to ensure that necessary maintenance is
performed on your NISSAN at regular intervals.GENERAL MAINTENANCEGeneral maintenance includes those items
which should be checked during normal day-
to-day operation. They are essential for proper
vehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks or inspections can be done by
yourself, a qualified technician or, if you prefer, a
NISSAN dealer.
WHERE TO GO FOR SERVICEIf maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and serviced by a NISSAN dealer.
NISSAN technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-dealership information systems.
They are completely qualified to work on
NISSAN vehicles
beforework begins.
You can be confident that a NISSAN dealer’s
service department performs the best job to
meet the maintenance requirements on your
vehicle — in a reliable and economical way. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, see “MAINTENANCE PRECAUTIONS”
later in this section.
EXPLANATION OF MAINTENANCE
ITEMSAdditional information on the following
items with “*” is found later in this section.Outside the vehicleThe maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, 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 lubrication frequently.

Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster: Check that the air
comes out of the defroster outlets properly and
in sufficient quantity when operating the heater
or air conditioner.
Windshield wiper and washer*: Check that
the wipers and washer operate properly and that
the wipers do not streak.Under the hood and vehicleThe maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel) .
Battery*: Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or under
severe condition require frequent checks of the
battery fluid level.
Brake and clutch fluid levels*: Make sure
that the brake and clutch fluid levels are
between the MAX and MIN lines on the
reservoirs.
Engine coolant level*: Check the coolant level
when the engine is cold.
Engine drive belts*: Make sure that no belt is
frayed, worn, cracked or oily. Engine oil level*:
Check the level after parking
the vehicle on a level spot and turning off the
engine. Wait more than 15 minutes for the oil to
drain back into the oil pan.
Exhaust system: Make sure there are no loose
supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of
exhaust fumes, immediately have the exhaust
system inspected by a NISSAN dealer. (See
“PRECAUTIONS WHEN STARTING AND
DRIVING” in the “5. St arting and driving”
section for exhaust gas (carbon monoxide) .)
Fluid leaks: Check under the vehicle for fuel,
oil, water or other fluid leaks after the vehicle has
been parked for a while. Water dripping from the
air conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evident,
check for the cause and have it corrected
immediately.
Power steering fluid level* and lines: Check
the level with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses: Check the front of the
radiator and clean off any dirt, insects, leaves,
etc., that may have accumulated. Make sure the
hoses have no cracks, deformation, rot or loose
connections. Underbody:
The underbody is frequently ex-
posed to corrosive substances such as those
used on icy roads or to control dust. It is very
important to remove these substances, other-
wise rust will form on the floor pan, frame, fuel
lines and around the exhaust system. At the end
of winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, see “CLEANING
EXTERIOR” in the “7. Appearance and care”
section.
Windshield washer fluid*: Check that there is
adequate fluid in the reservoir.8-4

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to yourself or
damage to the vehicle. The following are general
precautions which should be closely observed.
WARNING
.Park the vehicle on a level surface,
apply the parking brake securely
and block the wheels to prevent
the vehicle from moving. For man-
ual transmission models, move the
shift lever to N (Neutral) . For auto-
matic transmission models, move
the selector lever to P (Park) .
. Be sure the ignition switch is in the
OFF or LOCK position when per-
forming any parts replacement or
repairs.
. Never connect or disconnect the
battery or any transistorized com-
ponent while the ignition switch is
in the ON position.
. Never leave the engine or automatic
transmission related component
harnesses disconnected while the
ignition switch is in the ON position.
. If you must work with the engine running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
. It is advisable to secure or remove
any loose clothing and remove any
jewelry, such as rings, watches, etc.
before working on your vehicle.
. Always wear eye protection when-
ever you work on your vehicle.
. If you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it
is supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an
automatic engine cooling fan. It may
come on at any time without warn-
ing, even if the ignition key is in the
OFF position and the engine is not
running. To avoid injury, always
disconnect the negative battery cable before working near the fan.
. The fuel filter or fuel lines should be
serviced by a NISSAN dealer be-
cause the fuel lines are under high
pressure even when the engine is
off.
CAUTION
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly
disposed engine oil, coolant, and/
or other vehicle fluids can damage
the environment. Always conform to
local regulations for disposal of
vehicle fluid.
This “8. Maintenance and do-it-yourself” section
gives instructions regarding only those items
which are relatively easy for an owner to perform.
A genuine NISSAN Service Manual is also
available. (See “OWNER’S MANUAL/SERVICE
MANUAL ORDER INFORMATION” in the “9.

The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round anti-freeze
and coolant protection. The antifreeze solution
contains rust and corrosion inhibitors. Additional
engine cooling system additives are not neces-
sary.
WARNING
.Never remove the radiator or cool-
ant reservoir cap when the engine is
hot. Wait until the engine and
radiator cool down. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
See precautions in “IF YOUR VEHI-
CLE OVERHEATS” in the “6. In case
of emergency” section of this man-
ual.
. The radiator is equipped with a
pressure type radiator cap. To pre-
vent engine damage, use only a
genuine NISSAN radiator cap.
CAUTION
.When adding or replacing coolant,
be sure to use only Genuine NISSAN Long Life Antifreeze/Cool-
ant (blue) or equivalent. Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) is pre-diluted to provide
antifreeze protection to
34 8F
( 37 8C) . If additional freeze protec-
tion is needed due to weather where
you operate your vehicle, add Gen-
uine NISSAN Long Life Antifreeze/
Coolant (blue) concentrate follow-
ing the directions on the container.
If an equivalent coolant other than
Genuine NISSAN Long Life Anti-
freeze/Coolant (blue) is used, fol-
low the coolant manufacturer’s
instructions to maintain minimum
antifreeze protection to 34 8F
( 37 8C) . The use of other types of
coolant solutions other than Genu-
ine NISSAN Long Life Antifreeze/
Coolant (blue) or equivalent may
damage the engine cooling system.
. The life expectancy of the factory-fill
coolant is 105,000 miles (168,000
km) or 7 years. Mixing any other
type of coolant other than Genuine
NISSAN Long Life Antifreeze/Cool-
ant (blue) , including Genuine
NISSAN Long Life Antifreeze/Cool- ant (green) , or the use of non-
distilled water will reduce the life
expectancy of the factory-fill cool-
ant. Refer to the Nissan Service and
Maintenance Guide for more de-
tails.ENGINE COOLING SYSTEM8-8
