When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The fol-
lowing are general precautions which
should be closely observed.
WARNING
∙ Park the vehicle on a level surface, ap-ply the parking brake securely and
block the wheels to prevent the ve-
hicle from moving. Move the shif t le-
ver to P (Park).
∙ Be sure the ignition key is in the OFF or LOCK position when performing any
parts replacement or repairs.
∙ If you must work with the engine run- ning, 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 jew-
elry, such as rings, watches, etc. be-
fore working on your vehicle.
∙ Always wear eye protection whenever you work on your vehicle. ∙ Your vehicle is equipped with an auto-
matic 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 running. To
avoid injury, always disconnect the
negative battery cable before work-
ing near the fan.
∙ If you must run the engine in an en- closed 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 neces-
sary to work under the vehicle, sup-
port it with safety stands.
∙ Keep smoking materials, flame and sparks away from the fuel tank and
battery.
∙ On gasoline engine models, the fuel filter or fuel lines should be serviced. It
is recommended that you visit a
NISSAN dealer for this service because
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 contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
∙ Never leave the engine or the trans- mission related component harness
connector disconnected while the ig-
nition switch is in the ON position.
∙ Never connect or disconnect the bat- tery or any transistorized component
while the ignition switch is in the ON
position.
This “Do-it-yourself ” section gives instruc-
tions regarding only those items which are
relatively easy for an owner to perform.
A Genuine NISSAN service manual is also
available. For additional information, refer
to “Owner’s Manual/Service Manual order
information” in the “Technical and con-
sumer information” section of this manual.
You should be aware that incomplete or
improper servicing may result in operating
difficulties or excessive emissions, and
could affect warranty coverage. If in doubt
about any servicing, it is recommended
that you have it done by a NISSAN dealer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

WARNING
Be sure the engine and ignition switch
are off and that the parking brake is
engaged securely.
CAUTION
Be sure to use the correct socket to re-
move the spark plugs. An incorrect
socket can damage the spark plugs.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.
The air cleaner filter should not be cleaned
and reused. Replace it according to the
maintenance log shown in the “Mainte-
nance and schedules” section of this
manual. When replacing the filter, wipe the
inside of the air cleaner filter housing and
the cover with a damp cloth.
To remove the air cleaner filter:∙ Unlatch the clips
Aand move the air
cleaner cover upward.
∙ Remove the air cleaner filter.
∙ Wipe the inside of the air cleaner filter housing and cover with a damp cloth.
WARNING
∙ Operating the engine with the aircleaner removed can cause you or
others to be burned. The air cleaner
not only cleans the air, it stops the
flame if the engine backfires. If it isn’t
there, and the engine backfires, you
could be burned. Do not drive with the
air cleaner removed, and be careful
when working on the engine with the
air cleaner removed.
∙ Never pour fuel into the throttle body or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
IN-CABIN MICROFILTER
The in-cabin microfilter restricts the entry
of airborne dust and pollen particles and
reduces some objectionable outside
odors. The filter is located behind the glove
box. For additional information, refer to the
“Maintenance and schedules” section of
this manual for change intervals.
If replacement is required, it is recom-
mended that you visit a NISSAN dealer for
this service.

AIR CLEANER
8-16Do-it-yourself

Power steering fluid level* and lines:
Check the level when the fluid is cold, 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, defor-
mation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust may 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 accu-
mulate. For additional information, refer to
the “Appearance and care” section of this
manual.
Windshield-washer fluid*: Check that
there is adequate fluid in the reservoir. The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance schedule indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your vehicle requires that some items be
checked during normal day-to-day opera-
tion. For additional information, refer to
“General maintenance” in this section.
Items marked with
“*”are recommended
by NISSAN for reliable vehicle operation.
You are not required to perform mainte-
nance on these items in order to maintain
the warranties which come with your
NISSAN. Other maintenance items and in-
tervals are required.
When applicable, additional information
can be found in the “Do-it-yourself ” section
of this manual. NOTE:
NISSAN does not advocate the use of
non-OEM approved af termarket flush-
ing systems and strongly advises
against performing these services on a
NISSAN product. Many of the af termar-
ket flushing systems use non-OEM ap-
proved chemicals or solvents, the use of
which has not been validated by NISSAN.
For recommended fuel, lubricants, fluids,
grease, and refrigerant, refer to “Recom-
mended fluids/lubricants and capaci-
ties” in the “Technical and consumer in-
formation” section of this manual.
EMISSION CONTROL SYSTEM
MAINTENANCE:
Drive belts*:
Check engine drive belts for
wear, fraying or cracking and for proper
tension. Replace any damaged drive belts.
Engine air filter: Replace at specified inter-
vals. When driving for prolonged periods in
dusty conditions, check/replace the filter
more frequently.
