steep hill check that the 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 fluid level*:Make sure that the brake
fluid level is 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
and turning off the engine.
Power steering fluid level* and lines:Check
the level in the reservoir tank with the engine off.
Check the lines for proper attachment, leaks,
cracks, etc.
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 “Precautions when starting
and driving” in the “5. Starting and driving”
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 “Cleaning
exterior” in the “7. Appearance and care” 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
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 imme-
diately.8-4
Maintenance and do-it-yourself

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

Park the vehicle on a level surface,
apply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the selector
lever to the P (Park) position.

Be sure the ignition key is OFF or
LOCK when performing any parts re-
placement or repairs.

Your vehicle is equipped with an au-
tomatic engine cooling fan. It may
come on at any time without warning,
even if the ignition key is in the OFF
position and the engine is not run-
ning. To avoid injury, always discon-
nect the negative battery cable be-
fore working near the fan.

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 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 nec-
essary to work under the vehicle,
support it with safety stands.

Keep smoking materials, flame and
sparks away from fuel and the bat-
tery.

On gasoline engine models with the
Multiport Fuel Injection (MFI) Sys-
tem, the fuel filter or fuel lines shouldbe 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 off the engine
and wait until it cools down.

Never connect or disconnect either
the battery or any transistorized
component connector while the igni-
tion key is on.

Never leave the engine or the CVT
related component harness connec-
tor disconnected while the ignition
key is on.

Avoid 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.

Keep the battery surface clean and dry. Any
corrosion should be washed off with a solu-
tion of baking soda and water.

Make certain the terminal connections are
clean and securely tightened.

If the vehicle is not to be used for 30 days or
longer, disconnect the (—) negative battery
terminal cable to prevent discharging it.
WARNING

Do not expose the battery to flames
or electrical sparks. Hydrogen gas
generated by battery action is explo-
sive. Do not allow battery fluid to
contact your skin, eyes, fabrics, or
painted surfaces. After touching a
battery or battery cap, do not touch
or rub your eyes. Thoroughly wash
your hands. If the acid contacts your
eyes, skin or clothing, immediately
flush with water for at least 15 min-
utes and seek medical attention.

Do not operate the vehicle if the fluid
in the battery is low. Low battery fluid
can cause a higher load on the bat-tery which can generate heat, reduce
battery life, and in some cases lead
to an explosion.

When working on or near a battery,
always wear suitable eye protection
and remove all jewelry.

Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after han-
dling.

Keep the battery out of the reach of
children.
Check the fluid level in each cell. It should be
between the MAX and MIN lines.
If the side of the battery is not visible, the
electrolyte level can be checked through each
filler opening as illustrated.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening.Do not overfill.
Vehicles operated in high temperatures or under
severe conditions require frequent checks of the
battery fluid level.
