Maintain Your InvestmentPreventative scheduled maintenance is an important investment to
optimize the performance, durability, r eliability, safety and resale value
of your Infiniti. Scheduling your v ehicle’s maintenance at the
recommended intervals will ensure your vehicle is running at its best.
We want you to enjoy your Infiniti vehicle. This Service and Maintenance
Guide is designed to help you make sure your vehicle receives proper
and timely maintenance that is necessary. Key services are explained in
detail, along with an outline of scheduled maintenance to help you
maintain y our vehicle. Your local Infiniti retailer canassist you in
determining the best schedule based on your driving habits and local
conditions.
Failure to perform scheduled maintenance may result in excluding
portions of your vehicle from warranty coverage and may reduce the
performance, durability, reliabi lity, safety and/or resale value of your
vehicle. See your Warranty Information Booklet and Owner’s Manual for
details.
INFINITI MAINTENANCE
3

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.
