EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The
maintenance log indicates at which
mileage/time intervals each item requires
service.
In addition to scheduled maintenance,
your Infiniti requires that some items be
checked during normal day-to-day
operation. You can find these items listed
under “General Maintenance” in Chapter 8
of your Owner’s manual.
Items marked with “*” are recommended
by Infiniti for reliable vehicle operation. You
are not required to perform such mainte-
nance in order to maintain the emission
warranty or manufacturer recall liability.
Other maintenance items and intervals are
required.
When applicable, additional information
can be found in the “Do-it-yourself” sec-
tion 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.
