vehicle is held securely with the selector lever in
the P (Park) position without applying any
brakes.Under the hood and the vehicleThe maintenance items listed here should be
checked periodically (for example, each time you
check the engine oil or refuel).
Windshield washer fluid*:Check that there is
adequate fluid in the tank.
Engine coolant level*:Check the coolant level
when the engine is cold.
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, deterioration
or loose connections.
Brake and clutch fluid levels*:Make sure that
the brake and clutch fluid levels are between the
MAX and MIN lines on the reservoir.
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 conditions require frequent checks of the
battery fluid level.
Engine drive belts*:Make sure that no belt isfrayed, worn, cracked or oily.
Engine oil level*:Check the level on the
dipstick after parking the vehicle on a level spot,
turning off the engine and waiting 10 minutes.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine off.
Check the lines for proper attachment, leaks,

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 locate the trouble
and correct it. (See ªPrecautions when starting
and drivingº in the ª5. Starting and drivingº
section for exhaust gas (carbon monoxide).)
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 ªCleaning
exteriorº in the ª7. Appearance and careº sec-
tion.
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

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
IPark the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. For a manual
transmission, move the shift lever to
N (Neutral) position. For an auto-
matic transmission, move the selec-
tor lever to P (Park) position.
IBe sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.
IIf you must work with the engine
running, keep your hands, clothing,
hair and tools away from moving
fans, belts and any other moving
parts.
IIt is advised to secure or remove any
loose clothing and any jewelry, suchas rings, watches, etc. before work-
ing on your vehicle.
IAlways wear eye protection when-
ever you work on your vehicle.
IIf you must run the engine in an
enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
INever get under the vehicle while it is
supported only by a jack. If it is nec-
essary to work under the vehicle,
support it with safety stands.
IKeep smoking materials, flame and
sparks away from fuel and the bat-
tery.
IOn gasoline engine models with the
Multiport Fuel Injection (MFI) Sys-
tem, 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
IDo not work under the hood while
the engine is hot. Turn off the engine
and wait until it cools down.
INever connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.
INever leave the engine or the auto-
matic transmission related compo-
nent harness connector discon-
nected while the ignition key is on.
IAvoid direct contact with used engine
oil and coolant. Improperly disposed
engine oil, engine coolant and/or
other vehicle fluids can hurt the envi-
ronment. Always conform to local
regulations for disposal of vehicle
fluid.
