8-2Maintenance and do-it-yourself
GUID-AA55CBB0-36FE-4AE1-BB9F-D3DDA5B8D64FSome day-to-day and regular maintenance is
essential to maintain your vehicle's good me-
chanical 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. You are a vital link in the main-
tenance chain.
SCHEDULED MAINTENANCEGUID-65893F94-69E3-4F34-8FDD-B08F51DC5A57For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your ªNISSAN Service and
Maintenance Guideº. You must refer to that
guide to ensure that necessary maintenance is
performed on your vehicle at regular intervals.
GENERAL MAINTENANCEGUID-66FC02C8-9AF8-4D96-B4FC-1AEBE1F0B304General 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 SERVICEGUID-398932E5-71E3-483D-AF25-80EC94A6E2FAIf 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.
GUID-80D9D55F-69A7-48B4-8034-9DDC954A3984During 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 ªMaintenance precautionsº (P.8-5) .

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
operating properly and installed securely. Also
check headlight aim.
Road wheel nuts (lug nuts)*: When checking
the tires, make sure no wheel nuts are missing,
and check for any loose wheel nuts. Tighten if
necessary.
Tire rotation*: Tires should be rotated every
5,000 miles (8,000 km) .
Tires*: Check the pressure with a gauge often
and always prior to long distance trips. If
necessary, adjust the pressure in all tires,
including the spare, to the pressure specified.
Check carefully for damage, cuts or excessive
wear.
Tire Pressure Monitoring System (TPMS)
transmitter components: Replace the TPMS
transmitter grommet seal, valve core and cap
when the tires are replaced due to wear or age.
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 ªImportant Tire Safety Informationº (US) or
ªTire Safety Informationº (Canada) in the War-
ranty 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 windshield repaired by a qualified
repair facility.
Windshield wiper blades*: Check for cracks
or wear if they do not wipe properly.
Inside the vehicleGUID-3897C0E3-7461-4C2C-A02C-09726FC593F0The maintenance items listed here should be
checked on a regular basis, such as when
performing scheduled maintenance, cleaning
the vehicle, etc.
Accelerator pedal: Check the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort. Keep
the floor mat away from the pedal.
Brake pedal: Check the pedal for smooth
operation. If the brake pedal suddenly goes
down further than normal, the pedal feels
spongy or the vehicle seems to take longer to
stop, see a NISSAN dealer immediately. Keep
the floor mat away from the pedal.
Brakes: Check that the brakes do not pull the
vehicle to one side when applied. Continuously Variable Transmission (CVT)
P (Park) position mechanism:
On a fairly
steep hill, check that the vehicle is held securely
with the shift lever in the P (Park) position
without applying any brakes.
Parking brake: Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only the
parking brake applied. If the parking brake needs
adjustment, see a NISSAN dealer.
Seat belts: Check that all parts of the seat belt
system (for example, buckles, anchors, adjusters
and retractors) operate properly and smoothly,
and are installed securely. Check the belt
webbing for cuts, fraying, wear or damage.
Seats: Check seat position controls such as
seat adjusters, seatback recliner, etc. to ensure
they operate smoothly and that all latches lock
securely in every position. Check that the head
restraints/headrests move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
Steering wheel: Check for changes in the
steering conditions, such as excessive free play,
hard steering or strange noises.
Warning lights and chimes: Make sure that
all warning lights and chimes are operating
properly.

nance work on your vehicle, always take care
to prevent serious accidental injury to yourself or
damage to the vehicle. The following are general
precautions 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 vehicle from moving. Move the
shift lever to P (Park) .
. Be sure the ignition switch is in the

parts.
. It is advisable to secure or remove
any loose clothing and remove 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
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. 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
.Do not work under the hood while
the engine is hot. Turn the engine
off and wait until it cools down.
. Avoid direct contact with used en-
gine oil and coolant. Improperly
disposed engine oil, and 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 CVT
related component harnesses dis-
connected while the ignition switch
is in the ON position.
. Never connect or disconnect the
battery or any transistorized com-
ponent while the ignition switch is
