Your new NISSAN has been designed to have
minimum maintenance requirements with longer
service intervals to save you both time and
money. However, some day-to-day and regular
maintenance is essential to maintain your NIS-
SAN’s good mechanical condition, as well as its
emission and engine performance.
It is the owner’s responsibility to make sure that
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 “Service and Mainte-
nance 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 of the vehicle. They are essential if
your vehicle is to continue to operate properly. It
is your responsibility to perform these proce-
dures regularly as prescribed.Performing general maintenance checks require
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,
your NISSAN dealer.
Where to go for service:
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and tuned by 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 training programs. They
are completely qualified to work on NISSAN
vehiclesbeforethey work on your vehicle,
rather than after they have worked on it.
You can be confident that your NISSAN dealer’s
service department performs the best job to
meet the maintenance requirements of your ve-
hicle — in a reliable and economic 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
your NISSAN dealer check it promptly. In addi-
tion, you should notify your NISSAN dealer if you
think that repairs are required.
When performing any checks or maintenance
work, closely observe the “Maintenance precau-
tions” later in this section.
EXPLANATION OF GENERAL
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.
Tires*:
Check the pressure with a gauge at least once a
month and always prior to long distance trips. If
necessary, adjust the pressure in all tires, includ-
ing the spare, to the pressure specified. Check
carefully for damage, cuts or excessive wear.

Wheel nuts*:
When checking the tires, make sure no nuts are
missing, and check for any loose nuts. Tighten if
necessary.
Tire rotation*:
Tires should be rotated every 7,500 miles
(12,000 km). However, the timing for tire rotation
may vary according to your driving habits and
road surface conditions.
Wheel alignment and balance:
If the vehicle should pull to either side while
driving on a straight and level road, or if you
detect uneven or abnormal tire wear, there may
be a need for wheel alignment.
If the steering wheel or seat vibrates at normal
highway speeds, wheel balancing may be
needed.
For additional information regarding tires, refer to
“Important Tire Safety Information” (US) or “Tire
Safety Information” (Canada) in the Warranty
Information booklet.
Windshield:
Clean the windshield on a regular basis. Check
the windshield at least every six months for
cracks or other damage. Have a damaged wind-
shield repaired by a qualified repair facility.Windshield wiper blades*:
Check for cracks or wear if they do not wipe
properly.
Doors and engine hood:
Check that all doors and the engine hood oper-
ate properly. Also ensure that all latches lock
securely. Lubricate hinges, latches, 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. Make
sure that the headlights, stop lights, tail lights,
turn signal lights, and other lights are all operat-
ing properly and installed securely. Also check
headlight aim.
Inside the vehicleThe maintenance items listed here should be
checked on a regular basis, such as when
performing periodic maintenance, cleaning the
vehicle, etc.Warning lights and chimes:
Make sure that all warning lights and chimes are
operating properly.
Windshield wiper and washer*:
Check that the wipers and washer operate
properly and that the wipers do not streak.
Windshield defroster:
Check that the air comes out of the defroster
outlets properly and in sufficient quantity when
operating the heater or air conditioner.
Steering wheel:
Check for changes in the steering conditions,
such as excessive freeplay, hard steering or
strange noises.
Seats:
Check seat position controls such as seat ad-
justers, seatback recliner, etc. to ensure they
operate smoothly and that all latches lock se-
curely in every position. Check that the head
restraints move up and down smoothly and that
the locks (if so equipped) hold securely in all
latched positions.
Seat belts:
Check that all parts of the seat belt system (e.g.
buckles, anchors, adjusters and retractors) op-

erate properly and smoothly, and are installed
securely. Check the belt webbing for cuts, fray-
ing, wear or damage.
Accelerator pedal:
Check the pedal for smooth operation and make
sure the pedal does not catch or require uneven
effort. Keep the floor mats away from the pedal.
Clutch pedal*:
Make sure the pedal operates smoothly and
check that it has the proper free travel.
Brakes:
Check that the brakes do not pull the vehicle to
one side when applied.
Brake pedal and booster*:
Check the pedal for smooth operation and make
sure it has the proper distance under it when
depressed fully. Check the brake booster func-
tion. Be certain to keep floormats away from the
pedal.
Parking brake*:
Check that the lever has the proper travel and
confirm that your vehicle is held securely on a
fairly steep hill with only the parking brake ap-
plied.Automatic transmission P (Park) position
mechanism:
On a fairly steep hill check that your vehicle is
held securely with the selector lever in the P
position without applying any brakes.
Under the hood and vehicleThe maintenance items listed here should be
checked periodically e.g. each time you check
the engine oil or refuel.
Windshield washer fluid*:
Check that there is adequate fluid in the tank.
Engine oil level*:
Check the level after parking the vehicle on a
level spot and turning off the engine. (Be sure to
wait a few minutes to allow the oil to drain back
into the sump.)
Brake and clutch fluid levels*:
Make sure that the brake and clutch fluid level is
between the MAX and MIN lines on the reservoir.
Power steering fluid level* and lines:
Check the level when the fluid is cold and the
engine is turned off. Check the lines for proper
attachment, leaks, cracks, etc.Automatic transmission fluid level*:
Check the level after putting the selector lever in
P (Park) with the engine idling.
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 accumu-
lated. Make sure the hoses have no cracks,
deformation, rot or loose connections.
Engine drive belts*:
Make sure that no belt is frayed, worn, cracked
or oily.
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.
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 “Precau-
tions when starting and driving” in the “5. Start-

ing and driving” section for exhaust gas (carbon
monoxide).
Underbody:
The underbody is frequently exposed to corro-
sive substances such as those used on icy roads
or to control dust. It is very important to remove
these substances, otherwise rust will form on the
floor pan, frame, fuel lines and around the ex-
haust system. At the end of winter, the under-
body should be thoroughly flushed with plain
water, being careful to clean those areas where
mud and dirt may accumulate. For additional
information, see “Cleaning exterior” in the “7.
Appearance and care” section.
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.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. For a manual
transmission, move the shift lever to
Neutral. For an automatic transmis-
sion, move the selector lever to the P
(Park) position.
Be sure the ignition key is in the OFF
or LOCK position when performing
any replacement or repair.
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 battery.
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.

multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.
CAUTION
Do not work under the engine hood
while it 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 auto-
matic transmission related compo-
nent harness connector discon-
nected 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.
This section gives instructions regarding only
those items which are relatively easy for an
owner to perform. More involved service should
be done by your NISSAN dealer.
A genuine NISSAN Service Manual is also avail-
able. See “Owner’s Manual/Service Manual or-
der information” in the “9. Technical and con-
sumer information” section.
You should be aware that incomplete or im-
proper servicing may result in operating difficul-
ties or excessive emissions, and could affect
your warranty coverage.If in doubt about any
servicing, have it done by your NISSAN
dealer.8-6

The engine cooling system is filled at the factory
with a high-quality, year-round, anti-freeze cool-
ant solution. The anti-freeze solution contains
rust and corrosion inhibitors, therefore additional
cooling system additives are not necessary.
CAUTION
When adding or replacing the coolant,
be sure to use only a genuine NISSAN
anti-freeze coolant or equivalent with
the proper mixture ratio of 50% anti-
freeze and 50% demineralized water/
distilled water. The use of other types of
coolant solutions may damage your en-
gine cooling system.Outside tempera-

WARNING
Never remove the radiator cap when
the engine is hot. Serious burns
could be caused by high pressure
fluid escaping from the radiator. Wait
until the engine and radiator cool
down. See “If your vehicle overheats”
in the “6. In case of emergency” sec-
tion.
The radiator is equipped with a pres-
sure cap. To prevent engine damage,
use only a genuine NISSAN radiator
cap.
CHECKING ENGINE COOLANT
LEVELCheck the coolant level in the reservoir tank
when the engine is cold. If the coolant level is
below the MIN level, add coolant to the MAX
level. If the reservoir tank is empty, check the
coolant level in the radiatorwhen the engine is
cold.If there is insufficient coolant in the radia-
tor, fill the radiator with coolant up to the filler
opening and also add it to the reservoir tank up
to the MAX level.
If the engine cooling system frequently
requires coolant, have it checked by your
NISSAN dealer.
