tire/wheel on the front of the
vehicle. Doing so can damage
the vehicle or tire. Damage to
the tire may result in a sudden
loss of air pressure which may
cause loss of vehicle control in
some driving conditions and
cause a collision and personal
injury.
.Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.).

Tire wear and damage
WARNING
.Tires should be periodically in-
spected for wear, cracking, bul-
ging or objects caught in the
tread. If excessive wear, cracks,
bulging or deep cuts are found,
the tire(s) should be replaced.

.The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
.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. Replace the tires as
necessary to prevent tire failure
and possible personal injury.
.Improper service of the spare
tire may result in serious perso-
nal injury. If it is necessary to
repair the spare tire, it is re-
commended you visit an
INFINITI retailer for this ser-
vice.
.For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. (See “Speci-
fications” (P.10-11) for recommended types
and sizes of tires and wheels.)
After the ignition switch is placed in the ON
position, it may take a period of time for the
tire pressure to be displayed while the
vehicle is driven. Depending on the radio
wave circumstance, tire pressure may not
correctly be displayed.
WARNING
.The use of tires other than those
recommended or the mixed use of
tires of different brands, construc-
tion (bias, bias-belted, radial or run-
flat), or tread patterns can adversely
affect the ride, braking, handling,
ground clearance, body-to-tire clear-
ance, tire chain clearance, speed-
ometer calibration, headlight aim
and bumper height. Some of these
effects may lead to accidents and
could result in serious personal injury.
.For Two-Wheel Drive (2WD) models,
if your vehicle was originally
equipped with 4 tires that were thesame 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 condi-
tions and cause an accident and
personal injury.
.If the wheels are changed for any
reason, always replace with wheels
which have the same off-set dimen-
sion. Wheels of a different off-set
could cause premature tire wear,
degrade vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear. See “Wheels and tires” (P.10-
12) of this manual for wheel off-set
dimensions.
.Since the spare tire is not equipped
with the TPMS, when a spare tire is
mounted or a wheel is replaced, the
TPMS will not function and the low
tire pressure warning light will flash
for approximately 1 minute. The light
will remain on after 1 minute. Have
your tires replaced and/or TPMS
system reset as soon as possible. It
is recommended you visit an INFINITI
retailer for these services.
Do-it-yourself8-43

8-44Do-it-yourself
.Replacing tires with those not origin-
ally 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 handling the TPMS sensor.
.When replacing the TPMS sensor, the
ID registration may be required. It is
recommended you contact 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
correctly fitted. Otherwise the valve
may be clogged up with dirt and
cause a malfunction or loss of pres-
sure.
.Do not install a damaged or deformed
wheel or tire even if it has been
repaired. Such wheels or tires could
have structural damage and could fail
without warning.
.The use of retread tire is not recom-
mended.
.For additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety
Information” (Canada) in the War-ranty Information Booklet.
Intelligent All-Wheel Drive (AWD)
models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern
on all four wheels. Failure to do so
may result in a circumference differ-
ence between tires on the front and
rear axles which will cause excessive
tire wear and may damage the trans-
mission, transfer case and differential
gears.
.ONLY use spare tires specified for
the Intelligent AWD model.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with
tires of the same size, brand, construction
and tread pattern. The tire pressure and
wheel alignment should also be checked and
corrected as necessary. It is recommended
you visit an INFINITI retailer for this service.
Wheel balance
Unbalanced wheels may affect vehicle hand-
ling 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 mechanical damage.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in
the INFINITI Warranty Information Booklet.
Care of wheels
See “Cleaning exterior” (P.7-2) for details
about care of the wheels.
Spare tire (TEMPORARY USE
ONLY (T-type) spare tire) (if so
equipped)
Since the spare tire is not equipped with the
TPMS, when a spare tire is mounted (TEM-
PORARY USE ONLY), the Tire Pressure
Monitoring System (TPMS) will not function.
Observe the following precautions if the
TEMPORARY USE ONLY spare tire must be
used, otherwise your vehicle could be da-
maged or involved in an accident.

WARNING
.The TEMPORARY USE ONLY spare
tire should be used for emergency
use. It should be replaced with the
standard tire at the first opportunity
to avoid possible tire or differential
damage.
.Drive carefully while the TEMPOR-
ARY USE ONLY spare tire is installed.
Avoid sharp turns and abrupt braking
while driving.
.Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY
spare tire at 60 psi (420 kPa, 4.2
bar). Always keep the pressure of the
full size spare tire (if so equipped) at
the recommended pressure for stan-
dard tires, as indicated on the Tire
and Loading Information label. For
Tire and Loading Information label
location, see “Tire and loading infor-
mation label” (P.10-16).
.With the TEMPORARY USE ONLY
spare tire installed do not drive your
vehicle at speeds faster than 50 MPH
(80 km/h).
.When driving on roads covered with
snow or ice, the TEMPORARY USEONLY spare tire should be used on
the front wheels and original tire
used on the rear wheels (drive
wheels). Use tire chains only on the
two rear original tires.
.Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
.Do not use the spare tire on other
vehicles.
.Do not use more than one spare tire
at the same time.
CAUTION
.Do not use tire chains on a TEM-
PORARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
.Because the TEMPORARY USE
ONLY spare tire is smaller than the
original tire, ground clearance is re-
duced. To avoid damage to the
vehicle, do not drive over obstacles.
Also do not drive the vehicle through
an automatic car wash since it may
get caught.
Emergency tire puncture repair kit
(if so equipped)
The emergency tire puncture repair kit
(Emergency Tire Sealant) is supplied with
the vehicle instead of a spare tire. It can be
used to temporarily repair minor tire punc-
tures. If possible, have the vehicle towed to a
facility that can repair or replace the flat tire.
Using the emergency tire puncture repair kit
may cause a malfunction of the tire pressure
sensor and cause the low tire pressure
warning light to illuminate.
See “Flat tire” (P.6-3) for more details.

9-2Maintenance and schedules
Some day-to-day and regular maintenance
is essential to maintain your vehicle in good
mechanical condition, as well as its emission
and engine performance.
It is the owner’s responsibility to make sure
that the scheduled 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. 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. They are essential for
proper vehicle operation. It is your respon-
sibility 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 or inspections can be done by
yourself, a qualified technician or, if you
prefer, an INFINITI retailer.
SCHEDULED MAINTENANCE
The maintenance items listed in this section
are required to be serviced at regular inter-
vals. However, under severe driving condi-
tions, additional or more frequent
maintenance will be required.
WHERE TO GO FOR SERVICE
If maintenance service is required or your
vehicle appears to malfunction, have the
systems checked and serviced. It is recom-
mended you visit an INFINITI retailer for this
service.
INFINITI technicians are well-trained spe-
cialists 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 vehiclesbeforework 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 the normal day-to-day operation of
the vehicle, general maintenance should be
performed regularly as prescribed in this
section. If you detect any unusual sounds,
vibrations or smells, be sure to check for the
cause and have it checked promptly. In
addition, it is recommended you visit an
INFINITI retailer if you think that repairs are
required.

Tire rotation*:Tires should be rotated every
5,000 miles (8,000 km). If your vehicle is
equipped with different sized tires in the
front and rear, tires cannot be rotated.
Tires*:Check the pressure with a gauge
often and always prior to long distance trips.
If necessary, adjust the pressure in all tires,
including the spare, to the pressure speci-
fied. Check carefully for damage, cuts or
excessive wear.
Tire Pressure Monitoring System (TPMS)
transmitter components:Replace the TPMS
transmitter grommet seal, valve core and
cap when the tires are replaced due to wear
or age.
Wheel alignment and balance:If the vehicle
should pull to either side while driving on a
straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment.If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
For additional information regarding tires,
refer to “Important Tire Safety Information”
(US) or “Tire Safety Information” (Canada) in

It is recommended you visit an INFINITI
retailer for this service. Keep the floor mat
away from the pedal.
Brakes:Check that the brakes do not pull the
vehicle to one side when applied.
Parking brake:Check the parking brake
operation regularly. The vehicle should be
securely held on a fairly steep hill with only
the parking brake applied. If the parking
brake needs adjusted, it is recommended you
visit an INFINITI retailer for this service.
Seats:Check seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and that all
latches lock securely in every position. Check
that the head restraints move up and down
smoothly and that the locks (if so equipped)
hold securely in all latched positions.
Seat belts:Check that all parts of the seat
belt system (for example, buckles, anchors,
adjuster and retractors) operate properly
and smoothly, and are installed securely.
Check the belt webbing for cuts, fraying,
wear or damage.

play, hard steering or strange noises.
Maintenance and schedules9-3

9-4Maintenance and schedules
Warning lights and chimes:Make sure that
all warning lights and chimes are operating
properly.
Windshield defroster:Check that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating
the heater or air conditioner.
Windshield wiper and washer*:Check that
the wipers and washer operate properly and
that the wipers do not streak.
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*:Check the fluid level in each cell. It
should be between the MAX and MIN lines.
Vehicles operated in high temperatures or
under severe condition 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 electro-
nic accessories 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.
Brake fluid level*:Make sure that the brake
fluid level is between the MAX and MIN lines
on the reservoir.
Engine coolant level*:Check the coolant
level when the engine is cold.
Intercooler coolant level*:Check the coolant
level when the engine is cold.
Engine drive belts*:Make sure that no belt is
frayed, worn, cracked or oily.
Engine oil level*:Check the level after
parking the vehicle on a level spot and
turning off the engine. Wait more than 15
minutes for the oil to drain back into the oil
pan.
Exhaust system: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 inspected. It is recom-
mended you visit an INFINITI retailer for this
service. (See “Precautions when starting and
driving” (P.5-4).)
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 isnormal. If you should notice any leaks or if
gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:Check
the level when the fluid is cold, with the
engine off. Check the lines for proper
attachment, leaks, cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks, defor-
mation, rot or loose connections.
Underbody:The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust. It
is very important to remove these sub-
stances, otherwise rust will form 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 accu-
mulate. For additional information, see
“Cleaning exterior” (P.7-2).
Windshield washer fluid*:Check that there
is adequate fluid in the reservoir.

The following descriptions are provided to
give you a better understanding of the
scheduled maintenance items that should
be regularly checked or replaced. The main-
tenance schedule indicates at which mile-
age/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 maintenance” (P.9-2).
Items marked with “*” are recommended by
