When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self 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 mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•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 any jewelry, such as
rings, watches, etc. before working 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 by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.

MAINTENANCE FREE BATTERY
For a maintenance free battery it is not re-
quired to check the fluid level. However,
INFINITI recommends to visually check the
status of the green indicator
A(if so
equipped) periodically. If it is not visible, re-
place the battery as soon as possible.
MODELS WITH IDLE
STOP/START SYSTEM
•Ensure that the battery fitted is the special
battery that is enhanced with regard to the
charge-discharge capacity and life perfor-
mance. Avoid using any other battery for
the Idle Stop/Start System, as this may
cause early deterioration of the battery or
a malfunction of the Idle Stop/Start Sys-
tem. It is recommended that a Genuine
INFINITI battery is fitted. For more infor-
mation, it is recommended that you con-
tact an INFINITI retailer.
•If the battery terminal is disconnected (for
battery replacement, etc.) and then recon-
nected, there may be some delay before
the Stop/Start System reactivates.
BATTERY REPLACEMENT
It is recommended that a Genuine INFINITI
battery is fitted. It is recommended that you
visit an INFINITI retailer for this service.

Some 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 specified 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.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-
to-day operation of the vehicle. They are es-
sential if your vehicle is to continue to operate
properly. It is your responsibility to perform
these procedures regularly as prescribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.
These checks and inspections can be done by
yourself, a qualified technician, or if you pre-
fer, an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed under "Mainte-
nance schedules" later in this section are re-
quired to be serviced at regular intervals.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the sys-
tems checked and serviced. It is recom-
mended you visit an INFINITI retailer for this
service.
INFINITI technicians are well-trained spe-
cialists and are kept up to date with the latest
service information through technical bulle-
tins, service tips and training programs. They
are completely qualified to work on INFINITI
vehiclesbeforework begins.
You can be confident that an INFINITI retail-
er’s service department can perform the ser-
vice needed to meet the maintenance re-
quirements on your vehicle.During 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 smells, be sure to check for the cause or
have an INFINITI retailer do it promptly. In
addition, it is recommended you notify an
INFINITI retailer if you think that repairs are
required.
When performing any checks or maintenance
work, closely observe "Explanation of general
maintenance items" later in this section.
EXPLANATION OF GENERAL
MAINTENANCE ITEMS
