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 essential
if your vehicle is to continue to operate prop-
erly. 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 prefer,
an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed underMainte-
nance scheduleslater in this section are re-
quired to be serviced at regular intervals. How-
ever under severe driving conditions, additional
or more frequent maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your ve-
hicle appears to malfunction, have the systems
checked and serviced. It is recommended you
visit an INFINITI retailer for this service.
INFINITI technicians are well-trained specialists
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 vehiclesbefore
work begins.
You can be confident that an INFINITI retailer’s
service department can perform the service
needed to meet the maintenance requirements
on your vehicle.During normal day-to-day operation of the ve-
hicle, 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 observeExplanation of general
maintenance itemslater in this section.

fluid level in each cell. It should be between the
“UPPER” and “LOWER” lines. Vehicles operated
in high temperatures or under severe condi-
tions require frequent checks of the battery
fluid level.NOTE
Care should be taken to avoid situations that can
lead to potential battery discharge and potential
no-start conditions such as:
1. Installation or extended use of electronic ac-
cessories that consume battery power when
the engine is not running (Phone chargers,
GPS, DVD players, etc.)
2. Vehicle is not driven regularly and/or only
driven short distances.
In these cases, the battery may need to be

inspect more frequently
Tire rotation:
Tires should be rotated every 6,000 miles
(10,000 km) for 2WD, every 3000 miles (5000
km) for 4WD/AWD according to the instructions
underTire rotation*earlier in this section“Ge-
neral maintenance” in this section. When rotat-
ing tires, check for damage and uneven wear.
Replace if necessary.
Transmission fluid/oil, differential oil, transfer
case oil:
Visually inspect for signs of leakage at specified
intervals.To ensure smooth, trouble-free, safe and eco-
nomical driving, INFINITI provides two mainte-
nance schedules that may be used, depending
upon the conditions in which you usually drive.
These schedules contain both distance and
time intervals, up to 120,000 miles (192,000
km)/144 months. For most people, the odom-
eter reading will indicate when service is
needed. However, if you drive very little, your
vehicle should be serviced at the regular time
intervals shown in the schedule.
After 120,000 miles (192,000 km)/144 months,
continue maintenance at the same mileage/time
intervals.
ADDITIONAL MAINTENANCE ITEMS
FOR SEVERE OPERATING SYSTEMS
Additional maintenance items for severe oper-
ating conditions; should be performed on ve-
hicles that are driven under especially demand-
ing conditions. Additional maintenance items
should be performed if you primarily operate
your vehicle under the following conditions:
•Repeated short trips of less than 5 miles in
normal temperatures or less than 10 miles in
freezing temperatures.
•Stop-and-go traffic in hot weather or low
speed driving for long distances.
•Driving in dusty conditions or on rough,
muddy or salt-spread roads.
•Towing a trailer, or using a camper or car-top
carrier.
OIL CHANGE MONITOR
This vehicle is equipped with oil change moni-
tor. It calculates engine oil and filter change
interval base on driving conditions. Driving in
severe conditions will shorten the engine oil
and filter change interval. When the Engine Oil
– Service Due Now warning appears in the
vehicle information display, the engine oil and
filter need to be replaced.
NOTE
For vehicles operated in Canada, both standard
and severe maintenance items should be per-
formed at every interval.

Special service requirements
:
The prescribed service interval is based on
normal operation of the vehicle. Service work
will need to be performed more often if the
vehicle is operated under arduous conditions or
increased loads, for example:
•Regular city driving with frequent intermedi-
ate stops
•If the vehicle is primarily used to travel short
distance
9-8Maintenance and Schedules

•For frequent operation in mountainous ter-
rain or on poor road surfaces
•If the engine is often left idling for long
periods
In these or similar operating conditions, have,
for example, the air filter, engine oil and oil
filter changed more frequently. The tires must
be checked more frequently if the vehicle is
operated under increased loads. Further infor-
mation can be obtained at an INFINITI retailer.
