9-2Maintenance and schedules
Some day-to-day and regular maintenance
is essential to maintain your vehicle’s good
mechanical 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 maintenance chain.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-
to-day operation. They are essential for
proper vehicle operation. It is your respon-
sibility 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 or inspections can be done by
yourself, a qualified technician or, if you
prefer, an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed in this section
are required to be serviced at regular inter-
vals. However, under severe driving condi-
tions, additional or more frequent
maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems 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
bulletins, service tips, and training programs.
They are completely qualified to work on
INFINITI vehiclesbeforework begins.
You can be confident that an INFINITI
retailer’s service department performs the
best job to meet the maintenance require-
ments on your vehicle. During the normal day-to-day operation of
the vehicle, general maintenance should be
performed regularly as prescribed in this
section. If you detect any unusual sounds,
vibrations or smells, be sure to check for the
cause and have it checked promptly. It is
recommended to have an INFINITI retailer
do it promptly. In addition, it is recom-
mended you visit an INFINITI retailer if you
think that repairs are required.
When performing any checks or mainte-
nance work, closely observe “Maintenance
precautions” (P.8-2).

NANCE ITEMS
