EMISSION CONTROL SYSTEM
MAINTENANCE
Drive belts*:
Check engine drive belts for wear, fraying or
cracking and for proper tension. Replace any
damaged drive belts
Engine air filter*:
Replace at specified intervals. When driving for
prolonged periods in dusty conditions, check/
replace the filter more frequently.
Engine coolant*:
Replace coolant at the specified interval. When
adding or replacing coolant, be sure to use only
Genuine INFINITI Engine Coolant or equivalent
in its quality (BASF Glysantin® G40®). (For
additional information, refer toEngine cooling
systemin the9. Maintenance and Schedules
section.)NOTE
Mixing any other type of coolant or the use of
non-distilled water may reduce the recom-
mended service interval of the coolant.
Engine oil and oil filter:
Replace engine oil and oil filter at the specified
intervals. For recommended oil grade and vis-
cosity refer toRecommended fluids/lubricants
and capacitiesin the10. Technical informa-
tionsection.
Fuel filter:
Replace the fuel filter and drain the water at the
specified intervals.
Fuel lines*:
Check the fuel hoses, piping and connections
for leaks, looseness, or deterioration. Tighten
connections or replace parts as necessary.
Spark plugs:
Replace at specified intervals. Install new plugs
of the type as originally equipped.
CHASSIS AND BODY MAINTENANCE
Brake lines and cables:
Visually inspect for proper installation. Check
for chafing, cracks, deterioration, and signs of
leaking. Replace any deteriorated or damaged
parts immediately.
Brake pads, rotors, drums, & linings:
Check for wear, deterioration and fluid leaks.
Replace any deteriorated or damaged parts
immediately.
Exhaust system:
Visually inspect the exhaust pipes, muffler and
hangers for leaks, cracks, deterioration, and
damage. Tighten connections or replace parts
as necessary.
In-cabin microfilter:
Replace at specified intervals. When driving for
prolonged periods in dusty conditions, replace
the filter more frequently.
Propeller shaft(s):
Check for damage, looseness, and grease leak-
age. (4WD/AWD).
9-6Maintenance and Schedules

Steering gear and linkage, axle and suspension
parts, drive shaft boots:
Check for damage, looseness, and leakage of
oil or grease. Under severe driving conditions,
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.
MAINTENANCE SCHEDULES
Maintenance and Schedules9-7

MAINTENANCE SERVICE MESSAGES
The maintenance service interval display in-
forms you of the next service due date.
NOTE
The maintenance service interval display does
not show any information on the engine oil level.
The vehicle information display shows a service
message for a few seconds, e g:
•[Service A In .. days]
•[Service A Due]
•[Service A Exceeded by .. days]
Depending on the operating conditions of the
vehicle, the remaining time or distance until the
next service due date is displayed.
The letter indicates which service is due. A
stands for a minor service and B for a major
service. A number or another letter may be
displayed after the letter.
Only for certain countries: the position after the
letter A or B indicates any necessary additional
maintenance work. If you notify an INFINITI
retailer of this display, you will receive a state-
ment on the associated costs.The maintenance service interval display does
not take into account any periods of time during
which the battery is disconnected.
Maintaining the time-dependent service sched-
ule:
Note down the service due date displayed in the
vehicle information display before disconnect-
ing the battery.
or
After reconnecting the battery, subtract the
battery disconnection periods from the service
date shown on the display.Hiding service messages
Press the orbutton on the steering
wheel.
Displaying service messages
1. Switch the ignition on.
2. Press the
orbutton on the
steering wheel to select the [Serv.] menu.
3. Press the
orbutton to select
[Maintenance] submenu and confirm by
pressing the OK button.
The service due date appears in the vehicle
information display.
Information about service
Resetting the maintenance service interval dis-
play:
CAUTION
If the maintenance service interval display has
been inadvertently reset, this setting can be
corrected at an INFINITI retailer.
Have service work carried out as described in
the Maintenance Schedule. This may other-
wise lead to increased wear and damage to the
major assemblies or the vehicle.
An INFINITI retailer will reset the maintenance
service interval display after the service work
has been carried out. You can also obtain
further information on maintenance work, for
example.
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.
Maintenance and Schedules9-9

The following tables show the standard maintenance schedule. Depending upon weather and atmospheric conditions, varying road surfaces, individual
driving habits and vehicle usage, additional or more frequent maintenance may be required. After 120,000 miles (192,000 km)/144 months, continue
maintenance at the same mileage/time intervals.
