The following descriptions are pro-
vided to give you a better understand-
ing of the scheduled maintenance
items that should be regularly
checked or replaced. The mainte-
nance log indicates at which
mileage/time intervals each item re-
quires service.
In addition to scheduled mainte-
nance, your Infiniti requires that
some items be checked during nor-
mal day-to-day operation. You can
find these items listed under “Gen-
eral Maintenance” in Chapter 8 of
your Owner’s manual.
Items marked with“*”are recom-
mended by Infiniti for reliable vehicle
operation. You are not required to per-
form such maintenance in order to
maintain the emission warranty or
manufacturer recall liability. Other
maintenance items and intervals are
required. When applicable, additional informa-
tion can be found in the “Do-it-
yourself” section in Chapter 8 of your
Owner’s Manual.
NOTE:
Nissan North America
does not advocate the use
of non-OEM approved
aftermarket flushing
systems and strongly
advises against performing
these services on a Infinti
product. Many of the
aftermarket flushing
systems use non- OEM
approved chemicals or
solvents, the use of which
has not been validated by
Nissan North America.
For recommended fuel, lubricants,
fluids, grease, and refrigerant refer to
Chapter 9 in your Owner’s Manual.
