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 MAINTENANCE
For 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 MAINTENANCE
General 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 SERVICE
If 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” (P.8-6) .
EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The 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.
Lights*: Clean the headlights on a regular basis.
Maintenance and do-it-yourself8-3
MAINTENANCE REQUIREMENT GENERAL MAINTENANCE

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 vehicle
The 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” (P.5-2)
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” (P.7-2).
Windshield washer fluid*:
Check that there is
adequate fluid in the reservoir.

CHECKING ENGINE COOLANT LEVEL
Check the coolant levelin the reservoir when
the engine is running and after it reaches
normal operating temperature. If the coolant
level is below the MIN level
*2, add coolant up
to the MAX level
*1. If the reservoir is empty,
check the coolant level in the radiator when
the engine is cold. If there is insufficient
coolant in the radiator, fill the radiator with
coolant up to the radiator filler cap above the
radiator upper hose opening and also add it to
the reservoir up to the MAX level
*1. Put on the
filler cap above the radiator upper hose and with
the reservoir cap open, start the engine. Run the
engine until it reaches normal operating tem- perature. Add coolant up to the MAX level
*1.
Tighten the cap securely after adding engine
coolant.
If the cooling system requires coolant
frequently, have it checked by a NISSAN
dealer.
CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by a NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
. To avoid the danger of being
scalded, never change the coolant
when the engine is hot.
. Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator.
. Avoid direct skin contact with used
coolant. If skin contact is made,
wash thoroughly with soap or hand
cleaner as soon as possible. .
Keep coolant out of reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.
