•Tires degrade with age and use. Have tires,
including the spare, over 6 years old
checked by a qualified technician because
some tire damage may not be obvious. Re-
place the tires as necessary to prevent tire
failure and possible personal injury.
•Improper service of the spare tire may re-
sult in serious personal injury. If it is neces-
sary to repair the spare tire, it is recom-
mended that you visit an INFINITI retailer for
this service.
•For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada)
in the Warranty Information Booklet.
Tires should be periodically inspected for wear,
cracking, bulging or objects caught in the tread. If
excessive wear, cracks, bulging or deep cuts are
found, the tire should be replaced immediately.
The original tires have a built-in tread wear
indicator. When the wear indicator is visible,
the tire should be replaced.
Improper servicing of a tire may result in seri-
ous personal injury. If it is necessary to repair a
tire, it is recommended you contact an INFINITI
retailer.
TIRE ROTATION
INFINITI recommends rotating the tires every
5,000 miles (8,000 km).
For additional information on tire replacing
procedures, refer toFlat tirein the6. In case
of emergencysection.As soon as possible,
tighten the wheel nuts to the specified torque
with a torque wrench.
Wheel nut tightening torque: 96 ft-lb (130 N·m)
The wheel nuts must be kept tightened to speci-
fications at all times. It is recommended that
wheel nuts be tightened to specification at each
tire rotation interval.
WARNING
•After rotating the tires, check and adjust
the tire pressure.
•Do not include the spare tire in the tire
rotation.
•For additional information regarding tires,
refer toImportant Tire Safety Information
(US) orTire Safety Informationin the War-
ranty Information Booklet.
REPLACING WHEELS AND TIRES
WARNING
Do not install a deformed wheel or tire even if it
has been repaired. Such wheels or tires could
have structural damage and could fail without
warning.
When replacing a tire, use the same size, speed
rating and load carrying capacity as originally
equipped. (SeeWheels and Tiresin the9.
Maintenance and SchedulesMaintenance and
Schedulessection for recommended types and
sizes of tires and wheels.)
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, possibly
degraded vehicle handling characteristics
and/or interference with the brake discs/
drums. Such interference can lead to decreased
braking efficiency and/or early brake pad/shoe
wear.
8-34Do-it-yourself

Confirm the following for the TPMS:
WARNING
•The use of tires other than those recom-
mended or the mixed use of tires of different
brands, construction (bias, bias-belted or
radial), or tread patterns can adversely af-
fect the ride, braking, handling, VDC sys-
tem, ground clearance, body-to-tire clear-
ance, tire chain clearance, speedometer
calibration, headlight aim and bumper
height. Some of these effects may lead to
accidents and could result in serious per-
sonal injury.
•For 2WD models, if your vehicle was origi-
nally equipped with 4 tires that were the
same size and you are only replacing 2 of
the 4 tires, install the new tires on the rear
axle. Placing new tires on the front axle may
cause loss of vehicle control in some driving
conditions and cause an accident and per-
sonal injury.
•If the wheels are changed for any reason,
always replace with wheels which have the
same off-set dimension. Wheels of a differ-
ent off-set could cause premature tire wear,
degrade vehicle handling characteristics,
affect the VDC system and/or interferencewith the brake discs. Such interference can
lead to decreased braking efficiency and/or
early brake pad wear. For additional infor-
mation on wheel off-set dimensions, refer to
Wheels and Tiresin the9. Maintenance
and Schedulessection.
•When a replacement tire is mounted or a
wheel is replaced, the TPMS will not func-
tion and the low tire pressure warning light
will flash for approximately 1 minute. The
light will remain on after 1 minute. Contact
an INFINITI retailer as soon as possible for
tire replacement and/or system resetting.
•Replacing tires with those not originally
specified by INFINITI could affect the proper
operation of the TPMS.
•The TPMS sensor may be damaged if it is
not handled correctly. Be careful when han-
dling the TPMS sensor.
•When replacing the TPMS sensor, the ID
registration may be required. It is recom-
mended that you visit an INFINITI retailer for
ID registration.
•Do not use a valve stem cap that is not
specified by INFINITI. The valve stem cap
may become stuck.
•Be sure that the valve stem caps are cor-
rectly fitted. Otherwise the valve may be
clogged up with dirt and cause a malfunc-
tion or loss of pressure.
•Do not install a damaged or deformed wheel
or tire even if it has been repaired. Such
wheels or tires could have structural dam-
age and could fail without warning.
•The use of retread tires is not recom-
mended.
•For additional information regarding tires,
refer toImportant Tire Safety Information
(US) orTire Safety Information(Canada) in
the Warranty Information Booklet.
Care of wheels
•Wash the wheels when washing the vehicle
to maintain their appearance.
•Clean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.
•Do not use abrasive cleaners when washing
the wheels.
•Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss of
pressure or poor seal at the tire bead.
Do-it-yourself8-35
Page 483 of 531
•INFINITI recommends waxing the road
wheels to protect against road salt in areas
where it is used during winter.
WHEEL BALANCE
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can
get out of balance. Therefore, they should be
balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the wheels on the vehicle could lead to me-
chanical damage.
For additional information regarding tires, refer
toImportant Tire Safety Information(US) or
Tire Safety Information(Canada) in the War-
ranty Information Booklet.

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.

Under the hood and vehicle
The maintenance items listed here should be
checked periodically (for example, each time
you check the engine oil or refuel).
Battery*
:
Except for maintenance free battery, check the
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
charged to maintain battery health.

Make sure there are no loose supports, cracks
or holes. If the sound of the exhaust seems
unusual or there is a smell of exhaust fumes,
immediately have the exhaust system in-
spected. It is recommended you visit an INFINITI
retailer for this service. SeePrecautions when
starting and drivingin the5. Starting and
drivingsection.
Fluid leaks
:
Check under the vehicle for fuel, oil, water or
other fluid leaks after the vehicle has been
parked for a while. Water dripping from the air
conditioner after use is normal. If you should
notice any leaks or if gasoline fumes are evi-
dent, check for the cause and have it corrected
immediately.
Radiator and hoses
:
Check the front of the radiator and clean off any
dirt, insects, leaves, etc., that may have accu-
mulated. Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody
:
The underbody is frequently exposed to corro-
sive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust willform on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to clean
those areas where mud and dirt may accumu-
late. For additional information, seeCleaning
exteriorin the7. Appearance and caresec-
tion.
Windshield washer fluid*
:
Check that there is adequate fluid in the reser-
voir.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 schedule
indicates at which mileage/time intervals each
item requires service.
In addition to scheduled maintenance, your
vehicle requires that some items be checked
during normal day-to-day operation. Refer to
General maintenancein this section.
Items marked with “*” are recommended by
INFINITI for reliable vehicle operation. You are
not required to perform maintenance on these

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.
